Brehon B. Somervell.Brehon B. Somervell. [Source: Public domain]Construction begins on the Pentagon. The structure was conceived at the request of Brigadier General Brehon B. Somervell in 1941, in order to provide a temporary solution to the growing US War Department’s critical shortage of space. The groundbreaking ceremony takes place on September 11, 1941. [Fine, 1972, pp. 265-266, 348-351, 431-432, 434; PR Web, 1/16/2018] Exactly 60 years later, Flight 77 will crash into the Pentagon as part of the 9/11 attacks (see 9:37 a.m. September 11, 2001).

[Source: Airman]Fighter jets are regularly scrambled by the North American Aerospace Defense Command (NORAD) in response to suspicious or unidentified aircraft flying in US airspace in the years preceding 9/11. [General Accounting Office, 5/3/1994, pp. 4; Associated Press, 8/14/2002] For this task, NORAD keeps a pair of fighters on “alert” at a number of sites around the US. These fighters are armed, fueled, and ready to take off within minutes of receiving a scramble order (see Before September 11, 2001). [American Defender, 4/1998; Air Force Magazine, 2/2002; Bergen Record, 12/5/2003; Grant, 2004, pp. 14] Various accounts offer statistics about the number of times fighters are scrambled:
bullet A General Accounting Office report published in May 1994 states that “during the past four years, NORAD’s alert fighters took off to intercept aircraft (referred to as scrambled) 1,518 times, or an average of 15 times per site per year.” Of these incidents, the number of scrambles that are in response to suspected drug smuggling aircraft averages “one per site, or less than 7 percent of all of the alert sites’ total activity.” The remaining activity, about 93 percent of the total scrambles, “generally involved visually inspecting unidentified aircraft and assisting aircraft in distress.” [General Accounting Office, 5/3/1994, pp. 4]
bullet In the two years from May 15, 1996 to May 14, 1998, NORAD’s Western Air Defense Sector (WADS), which is responsible for the “air sovereignty” of the western 63 percent of the continental US, scrambles fighters 129 times to identify unknown aircraft that might be a threat. Over the same period, WADS scrambles fighters an additional 42 times against potential and actual drug smugglers. [Washington National Guard, 1998]
bullet In 1997, the Southeast Air Defense Sector (SEADS)—another of NORAD’s three air defense sectors in the continental US—tracks 427 unidentified aircraft, and fighters intercept these “unknowns” 36 times. The same year, NORAD’s Northeast Air Defense Sector (NEADS) handles 65 unidentified tracks and WADS handles 104 unidentified tracks, according to Major General Larry Arnold, the commander of the Continental United States NORAD Region on 9/11. [American Defender, 4/1998]
bullet In 1998, SEADS logs more than 400 fighter scrambles. [Grant, 2004, pp. 14]
bullet In 1999, Airman magazine reports that NORAD’s fighters on alert at Homestead Air Reserve Base in Florida are scrambled 75 times per year, on average. According to Captain Tom Herring, a full-time alert pilot at the base, this is more scrambles than any other unit in the Air National Guard. [Airman, 12/1999]
bullet General Ralph Eberhart, the commander of NORAD on 9/11, will later state that in the year 2000, NORAD’s fighters fly 147 sorties. [9/11 Commission, 6/17/2004 pdf file]
bullet According to the Calgary Herald, in 2000 there are 425 “unknowns,” where an aircraft’s pilot has not filed or has deviated from a flight plan, or has used the wrong radio frequency, and fighters are scrambled 129 times in response. [Calgary Herald, 10/13/2001]
bullet Between September 2000 and June 2001, fighters are scrambled 67 times to intercept suspicious aircraft, according to the Associated Press. [Associated Press, 8/14/2002]
Lieutenant General Norton Schwartz, the commander of the Alaskan NORAD Region at the time of the 9/11 attacks, will say that before 9/11, it is “not unusual, and certainly was a well-refined procedure” for NORAD fighters to intercept an aircraft. He will add, though, that intercepting a commercial airliner is “not normal.” [Air Force Magazine, 9/2011 pdf file] On September 11, 2001, NEADS scrambles fighters that are kept on alert in response to the hijackings (see 8:46 a.m. September 11, 2001 and 9:24 a.m. September 11, 2001).

A 20-year-old Ethiopian man hijacks a Lufthansa Airbus bound from Frankfurt to Addis Ababa, via Cairo. Wielding a gun (which is subsequently found to be just a starter pistol), he forces the pilot to divert the plane to New York. The 11-hour ordeal ends after the plane lands at JFK International Airport and the hijacker surrenders to the FBI. [CNN, 3/14/1996; Guardian, 2/8/2000; 9/11 Commission, 7/24/2004, pp. 457]
Fears of Plane Being Crashed - Journalist Eric Margolis, who is on the plane, will later say that he and the other passengers are “convinced the hijacker… intended to crash the plane into Manhattan.” [Eric Margolis (.com), 2/13/2000] While giving television commentary on the morning of 9/11, Larry Johnson—currently the deputy director of the State Department’s Office of Counter Terrorism—will say it was feared when the plane was flown to New York “that it might be crashed into something.” [NBC, 9/11/2001]
Air Force Responds - In response to the hijacking, F-15 fighter jets are scrambled from Otis Air National Guard Base in Cape Cod, Massachusetts, from where fighters will also be launched in response to the first hijacking on 9/11 (see 8:46 a.m. September 11, 2001). Later, F-16s are scrambled from Atlantic City, New Jersey. The fighters intercept the Lufthansa aircraft off the coast of eastern Canada, and initially trail it from a distance of about ten miles. As the plane approaches JFK Airport, the fighters move in to a distance of five miles. They do a low fly-by as the plane lands at JFK. They circle overhead for a while, until the hijacking situation is resolved, and then return to their bases. [Spencer, 2008, pp. 29]
Participants in Response Also Involved on 9/11 - This is the last hijacking to occur prior to 9/11 involving US air traffic controllers, FAA management, and military coordination. [9/11 Commission, 7/24/2004, pp. 14; Utica Observer-Dispatch, 8/5/2004] At least two of the military personnel who participate in the response to it will play key roles in responding to the 9/11 attacks. Robert Marr, who on 9/11 will be the battle commander at NORAD’s Northeast Air Defense Sector (NEADS), is currently the assistant deputy commander of operations at Griffiss Air Force Base in Rome, NY. [Post-Standard (Syracuse), 3/27/2005] On this occasion, he talks with his counterpart at the FAA and explains that the FAA needs to start a request up its chain of command, so the military can respond quickly if the hijacking—which takes place in Europe—comes to the United States. He then informs his own chain of command to be prepared for a request for military assistance from the FAA. Several hours later, Marr is notified that military assistance has been authorized, and the fighter jets are scrambled from Otis and Atlantic City. [Spencer, 2008, pp. 26-27] Timothy Duffy, who will be one of the F-15 pilots that launches from Otis Air Base in response to the first hijacking on 9/11, is also involved. His role on this occasion is unreported, though presumably he pilots one of the jets scrambled from Otis after the Lufthansa plane. [Spencer, 2008, pp. 29]

Robert Marr, who on 9/11 will be the battle commander at NORAD’s Northeast Air Defense Sector (NEADS), gains experience in military training exercises. After flying on active duty for nearly 18 years, in 1994 Marr leaves the service. For 20 months, he works as the captain of a Lear 36 business jet that is contracted as part of a simulated “target force,” hired to stage attacks on the United States. In 1996 he returns to NEADS as the director of exercise and analysis. In this post, Marr no doubt gains further experience around military exercises. In 1998, he is named vice commander of NEADS, and in 1999 he will be promoted to become the commander of NEADS. [Post-Standard (Syracuse), 3/27/2005; Spencer, 2008, pp. 5-6] Marr’s particular experience around military exercises is notable, since NEADS will be in the middle of a major training exercise on the morning of 9/11 (see (6:30 a.m.) September 11, 2001).

The Alfred P. Murrah Building after being bombed.The Alfred P. Murrah Building after being bombed. [Source: CBS News]A truck bomb destroys the Alfred P. Murrah Federal Building in Oklahoma City, killing 168 people in America’s worst domestic terrorist attack. Timothy McVeigh, later convicted in the bombing, has ideological roots both in the Patriot world and among neo-Nazis like William Pierce, whose novel, The Turner Diaries (see 1978), served as a blueprint for the attack. [Washington Post, 4/20/1995; Southern Poverty Law Center, 6/2001; Clarke, 2004, pp. 127] Initially, many believe that no American set off the bomb, and suspect Islamist terrorists of actually carrying out the bombing (see 10:00 a.m. April 19, 1995 and After). Their suspicions prove groundless. Investigators will find that the bomb is constructed of some 5,000 pounds of ammonium nitrate and fuel oil, carried in 20 or so blue plastic 55-gallon barrels arranged inside a rented Ryder truck (see April 15, 1995). The bomb is detonated by a slow-burning safety fuse, most likely lit by hand. The fuse is attached to a much faster-burning detonation cord (“det cord”) which ignites the fertilizer and fuel-oil mixture. [New York Times, 4/27/1995] The Murrah Federal Building houses a number of federal agencies, including offices for the Bureau of Alcohol, Tobacco and Firearms (BATF); the Social Security Administration; the Housing and Urban Development (HUD), Veterans Affairs, and Agriculture departments; and the Secret Service. [Washington Post, 4/20/1995] It encompasses an entire city block, between 5th and 4th Streets and Harvey and Robinson Streets, and features a U-shaped, indented drive on 5th that allows for quick pickup and delivery parking. The entire building’s facade on this side is made of glass, allowing passersby to see into the offices in the building, as well as into the America’s Kids day care center on the second floor, which by this time is filling with children. It is in this driveway that McVeigh parks his truck. [Serrano, 1998, pp. 99-102]
Entering the City - McVeigh drives into Oklahoma City, entering around 8:30 a.m. from his overnight stop in Ponca City, Oklahoma; the details reported of his entrance into the city vary (see 7:00 a.m. - 8:35 a.m., April 19, 1995). At 8:55 a.m., a security camera captures the Ryder truck as it heads towards downtown Oklahoma City [Douglas O. Linder, 2006] , a sighting bolstered by three people leaving the building who later say they saw the truck parked in front of the Murrah Building around this time. At 8:57, a security camera captures an image of McVeigh’s Ryder truck being parked outside the Murrah Building in a handicapped zone. One survivor of the blast, Marine recruiter Michael Norfleet, later recalls seeing the Ryder truck parked just outside the building next to the little circle drive on 5th Street leading up to the main entrance of the building. Norfleet had parked his black Ford Ranger in front of the Ryder.
McVeigh Lights Fuses - McVeigh drives the Ryder truck west past the Murrah Building on NW Fourth Street, turns north on a one-way street, and turns right on Fifth Street. He pulls the truck over and parks near the Firestone store, next to a chain-link fence. He then lights the five-minute fuses from inside the cab (see 8:15 a.m. and After, April 18, 1995), sets the parking brake, drops the key behind the seat, opens the door, locks the truck, exits, and shuts the door behind him. A man later claims to have hit his brakes to avoid someone matching McVeigh’s description as he crossed Fifth Street around 9:00 a.m. McVeigh walks quickly toward a nearby YMCA building where he has hidden his getaway car, a battered yellow Mercury Marquis (see April 13, 1995), in the adjoining alleyway, crossing Robinson Street and crossing another street to get to the alleyway. He begins to jog as he approaches his car. He later says he remembers a woman looking at him as she is walking down the steps to enter the building; he will describe her as white, in her mid-30s, with dirty blonde hair. According to McVeigh’s own recollection, he is about 20 feet into the alley when the bomb goes off. [Stickney, 1996, pp. 184-185; PBS Frontline, 1/22/1996; Serrano, 1998, pp. 158; Douglas O. Linder, 2006; The Oklahoman, 4/2009]
Truck Explodes - At 9:02 a.m., the truck explodes, destroying most of the Murrah Building and seriously damaging many nearby buildings. Eventually, it will be determined that 168 people die in the blast, including 19 children. Over 500 are injured. The children are in the second-story day care center just above the parking space where McVeigh leaves the Ryder truck. McVeigh will later tell his biographers that he is lifted off his feet by the power of the blast.
Devastation and Death - When the bomb detonates, the day care center and the children plummet into the basement. The building, constructed with large glass windows, collapses, sending a wave of flying glass shards and debris into the building and the surrounding area. The oldest victim is 73-year-old Charles Hurlbert, who has come to the Social Security office on the first floor. Hurlbert’s wife Jean, 67, also dies in the blast. The youngest victim is four-month-old Gabeon Bruce, whose mother is also in the Social Security office. One victim, Rebecca Anderson, is a nurse who runs towards the building to render assistance. She never makes it to the building; she is struck in the head by a piece of falling debris and will die in a hospital four days after the blast. Her heart and kidneys will be transplanted into survivors of the bombing. [Denver Post, 6/3/1997; New York Times, 6/3/1997; Serrano, 1998, pp. 153-154; Oklahoma City Journal Record, 3/29/2001] Sherri Sparks, who has friends still unaccounted for in the building, tells a reporter in the hours after the blast, “Oh, I can’t stand the thought of… those innocent children, sitting there playing, thinking they’re safe, and then this happens.” The explosion leaves a 30-foot-wide, 8-foot-deep crater in the street that is covered by the wreckage of the building’s upper floors. The north face of the nine-story building collapses entirely. [Washington Post, 4/20/1995; Washington Post, 4/22/1995] Mary Heath, a psychologist who works about 20 blocks from the Murrah Building, says the blast “shook the daylights out of things—it scared us to death. We felt the windows shake before we heard the noise.” In a neighboring building, a Water Resources Board meeting is just commencing; the audiotape of the meeting captures the sound of the blast (see 9:02 a.m. and After, April 19, 1995). [Washington Post, 4/20/1995; The Oklahoman, 4/2009] Norfleet, trapped in the Marine Corps office, is thrown into a wall by the explosion. His skull is fractured, and a shard of glass punctures his right eye. Three separate arteries are pierced, and Norfleet begins bleeding heavily. Two supply sergeants in the office are far less injured; Norfleet asks one, “How bad am I hurt?” and one replies, “Sir, you look really bad.” One of the two begins giving Norfleet first aid; Norfleet later recalls: “He immediately went into combat mode and started taking care of me. He laid me on a table and he started looking for bandages to administer first aid. And while I was laying on that table, I just knew that I was losing strength and that if I stayed in the building, I would die.” Norfleet wraps a shirt around his head and face to slow the bleeding, and the two sergeants help him to the stairs, through the fallen rubble, and eventually out. Norfleet will later say that he follows “a blood trail of somebody that had gone down the steps before me” to get outside, where he is quickly put into an ambulance. He loses almost half his body’s blood supply and his right eye. He will never fly again, and will soon be discharged for medical incapacity. [Serrano, 1998, pp. 161-162] Eighteen-month-old Phillip Allen, called “P.J.” by his parents, miraculously survives the blast. The floor gives way beneath him and he plunges 18 feet to land on the stomach of an adult worker on the floor below, Calvin Johnson. Landing on Johnson’s stomach saves P.J.‘s life. Johnson is knocked unconscious by the blast and by the impact of the little boy falling on him, but when he awakes, he carries the toddler to safety. P.J.‘s grandfather calls the child “Oklahoma’s miracle kid,” and media reports use the label when retelling the story of the miraculous rescue. P.J. is one of six children in the day care center to survive the blast. [Stickney, 1996, pp. 275-277] Some people later report their belief that the Murrah Building was rocked by a second explosion just moments after the first one, the second coming from a secure area managed by the Bureau of Alcohol, Tobacco and Firearms (BATF) that illegally stored explosives. Law professor Douglas O. Linder will later write, “Both seismic evidence and witness testimony supports the ‘two blast theory.’” [Douglas O. Linder, 2006] That theory is later disputed (see After 9:02 a.m. April 19, 1995).
Explosion's Effects Felt Miles Away - Buildings near the Murrah are also damaged, seven severely, including the Journal Record newspaper building, the offices of Southwestern Bell, the Water Resources Board, an Athenian restaurant, the YMCA, a post office building, and the Regency Tower Hotel. Two Water Resources Board employees and a restaurant worker are killed in the blast. The Journal Record building loses its roof. Assistant Fire Chief Jon Hansen later recalls, “The entire block looked like something out of war-torn Bosnia.” Every building within four blocks of the Murrah suffers some effects. A United Parcel Service truck 10 miles away has its windows shattered by the blast. Cars in parking lots around the area catch fire and burn. Millions of sheets of paper, and an innumerable number of glass shards, shower down for hundreds of feet around the building. [Stickney, 1996, pp. 28-30]
Truck Axle Crushes Nearby Car - Richard Nichols (no relation to bomber Timothy McVeigh’s co-conspirator Terry Nichols), a maintenance worker standing with his wife a block and a half away from the Murrah Building, is spun around by the force of the blast. They throw open the back door of their car and begin taking their young nephew Chad Nichols out of the back seat, when Richard sees a large shaft of metal hurtling towards them. The “humongous object… spinning like a boomerang,” as Richard later describes it, hits the front of their Ford Festiva, smashing the windshield, crushing the front end, driving the rear end high into the air, and sending the entire car spinning backwards about 10 feet. Chad is not seriously injured. The metal shaft is the rear axle of the Ryder truck. Later, investigators determine that it weighs 250 pounds and was blown 575 feet from where the truck was parked. Governor Frank Keating (R-OK) points out the axle to reporters when he walks the scene a day or so later, causing some media outlets to incorrectly report that Keating “discovered” the axle. The scene will take investigators days to process for evidence. [Stickney, 1996, pp. 32; New York Times, 6/3/1997; Serrano, 1998, pp. 187-189]
First Responders Begin Arriving - Within minutes, survivors begin evacuating the building, and first responders appear on the scene (see 9:02 a.m. - 10:35 a.m. April 19, 1995).
McVeigh's Getaway - McVeigh flees the bomb site in his Mercury getaway car (see 9:02 a.m. and After, April 19, 1995), but is captured less than 90 minutes later (see 9:03 a.m. -- 10:17 a.m. April 19, 1995).

At its operations center in Cheyenne Mountain, Colorado, the North American Aerospace Defense Command (NORAD) practices dealing with hijackings five times per month, on average, during training exercises. A NORAD document produced a month after 9/11 will state that the Cheyenne Mountain Operations Center (CMOC) “routinely conducts the Amazon Arizona series of internal exercises that include hijack scenarios.” Prior to September 11, 2001, the document continues, “CMOC averaged five hijack training events each month.” Further details of these “Amazon Arizona” exercises are unstated in the document. [North American Aerospace Defense Command, 10/13/2001] But other sources provide additional information about what they might entail.
Exercises Are 'One of the Busiest Times' in Operations Center - According to a 1989 NORAD document, “Arizona” exercises are a “Cheyenne Mountain Air Force Base internal system training mission.” [North American Aerospace Defense Command, 8/25/1989] And in 2004, NORAD will state that its exercises before 9/11 that include hijacking scenarios test “track detection and identification; scramble and interception; hijack procedures; internal and external agency coordination; and operational security and communications security procedures.” [CNN, 4/19/2004] According to Stacey Knott, a technician at the CMOC, “One of the busiest times” in the operations center “is during exercises.… We have the battle staff and CAT [Crisis Action Team] in here; generals and admirals are running in and out.” Knott has said that exercises at the CMOC give her “an idea what things would be like if something were to go down,” and so, “[i]f something actually did happen, we’d be ready for it.” [Airman, 1/1996]
Operations Center Is 'Focal Point for Air Defense Operations' - It is unclear over what period up to 9/11 the CMOC averages five hijack training events per month. It appears to be at least going back to 1998: In 2003, Ken Merchant, NORAD’s joint exercise design manager, will tell the 9/11 Commission that his office keeps computer hard drive information about NORAD exercises “roughly” back to that year. Merchant will add that he “did not believe that his office retained other exercise information, such as after-action reviews, for exercises prior to 1998.” [9/11 Commission, 11/14/2003 pdf file] According to NORAD’s website, “the Cheyenne Mountain Operations Center provides warning of ballistic missile or air attacks against North America, assists the air sovereignty mission for the United States and Canada, and, if necessary, is the focal point for air defense operations to counter enemy bombers or cruise missiles.” [North American Aerospace Defense Command, 11/27/1999] On the morning of 9/11, members of the battle staff at the CMOC will be participating in the exercise Vigilant Guardian (see (6:30 a.m.) September 11, 2001).

John Hamre.John Hamre. [Source: R. D. Ward / US Department of Defense]The North American Aerospace Defense Command (NORAD) conducts an exercise, called Vigilant Virgo 99-1, in which simulated missiles are injected into its radar systems, apparently similar to the way simulated information will be injected onto its radar screens for a training exercise on the morning of September 11, 2001. [US Department of Defense, 1/15/1999; Toronto Star, 12/9/2001; Arkin, 2005, pp. 546] In August 1998, Secretary of Defense William Cohen directed the commanders in chief who are responsible for the Department of Defense’s unified combatant commands to plan, carry out, and report on a series of simulated Year 2000 “operational evaluations.” [United States General Accounting Office, 6/1999, pp. 8 pdf file; United States General Accounting Office, 11/1999, pp. 15 pdf file] Vigilant Virgo is the first in a series of NORAD operational evaluations that are going to be held in response to this order. [US Department of Defense, 1/15/1999; United States General Accounting Office, 6/1999, pp. 2 pdf file; Military Operations Research Society, 6/22/1999, pp. 193 pdf file]
Exercise Tests NORAD's Year 2000 Preparedness - The three-day exercise is intended to evaluate if NORAD’s systems are vulnerable to the Year 2000 (Y2K) computer problem, which would be caused by computers being unable to properly read dates at the start of the new millennium. [US Department of Defense, 1/15/1999; New York Times, 2/9/1999] It evaluates the capability of NORAD’s systems to track and forward information about missile and space air threats when the command’s clocks are rolled forward to January 1, 2000. [United States General Accounting Office, 6/1999, pp. 8-9 pdf file] The exercise is a collaborative effort in which NORAD is supported by personnel, equipment, and facilities belonging to the US Space Command and the US Strategic Command. [US Department of Defense, 1/14/1999; US Department of Defense, 1/15/1999]
'Missile Events' Are Injected into NORAD's Sensors - Vigilant Virgo focuses on the missile warning element of NORAD’s integrated tactical warning and attack assessment function. [United States General Accounting Office, 6/1999, pp. 11 pdf file; Military Operations Research Society, 6/22/1999, pp. 193 pdf file] It involves “well over 30 missile events” being “injected” into NORAD’s sensors, according to Lieutenant Colonel Warren Patterson, a member of the Joint Staff Year 2000 Task Force. These simulated events involve data that is injected “as though it [is] being sensed for the first time by a radar site,” Deputy Secretary of Defense John Hamre will later describe. Some of the simulations involve mass attacks, while others involve attacks by a single missile. [US Department of Defense, 1/15/1999] The Y2K preparedness of the entire ground radar array network is analyzed during the exercise. [Bulletin of the Atomic Scientists, 3/1999]
Exercise Finds No Vulnerabilities in NORAD's Systems - Vigilant Virgo will be considered a success. The exercise will find that there is “no degradation in any of the systems, whether they were in the Year 2000 environment, the virtual Year 2000 environment, or whether they were in the real world, 1998 environment,” Patterson will say. “We are highly confident now, at this point, that CINC [commander in chief] NORAD can do his early warning mission,” he will conclude. [US Department of Defense, 1/15/1999]
Exercise on 9/11 Will Use Simulated Radar Information - NORAD is the military organization responsible for monitoring and defending North American airspace. [9/11 Commission, 7/24/2004, pp. 16; Department of National Defence, 7/25/2017] Personnel at its Northeast Air Defense Sector (NEADS), based in Rome, New York, will be responsible for coordinating the military’s response to the 9/11 hijackings. [Shenon, 2008, pp. 203] It will be conducting an exercise on the morning of September 11, 2001, which, like Vigilant Virgo, involves simulated information being injected onto its radar screens (see (9:00 a.m.) September 11, 2001, 9:34 a.m. September 11, 2001, and 10:12 a.m. September 11, 2001). [Toronto Star, 12/9/2001] NORAD will conduct a follow-on exercise to Vigilant Virgo from February 15 to February 28, 1999, called Amalgam Virgo 99-2, which will involve a comprehensive evaluation of its systems for aerospace control, air warning, missile warning, and space warning. [United States General Accounting Office, 6/1999, pp. 11 pdf file; Arkin, 2005, pp. 253-254] Whether that exercise will involve simulated information being injected onto radar screens is unclear.

As the military community is discussing the future of continental air defense in a post-Cold War world (see May 19, 1997), Major General Larry Arnold, the commander of the 1st Air Force, orders a study to review the Air Force’s air sovereignty mission. At his request, Major General Paul Pochmara forms a 12-member roles and mission (RAM) team to gather information and ideas on the subject. The team has a one-hour presentation that outlines the military’s responsibility for protecting the nation’s air sovereignty. Major General Mike Haugen, a member of the team, will later say that the group discusses everything from technology to the future of the air sovereignty mission to the terrorist threat. Haugen will say: “We made some pretty bold predictions in our briefing.… In fact, it included a photo of Osama bin Laden as the world’s most dangerous terrorist.… We didn’t predict how the terrorists would strike but predicted they would strike.” [Filson, 2003, pp. 37-38] A 9/11 Commission memorandum will add, “Osama bin Laden is featured on the cover of the brief developed by the RAM team, and he figures prominently in the study.” Colonel Alan Scott of the Continental US NORAD Region will tell the Commission: “As we started talking about Osama bin Laden, the examples we gave in our mission brief were the first WTC bombing, the Tokyo subway, Oklahoma City bombing, and Atlanta Olympics. What we did was connect those dots. The conclusion we drew was that we had a viable threat.” [9/11 Commission, 6/9/2004]

Giuliani’s emergency command center.Giuliani’s emergency command center. [Source: CNN]New York City Mayor Rudolph Giuliani opens a $13 million emergency command center on the 23rd floor of World Trade Center Building 7. [Newsday, 9/12/2001] The center is intended to coordinate responses to various emergencies, including natural disasters like hurricanes or floods, and terrorist attacks. The 50,000 square foot center has reinforced, bulletproof, and bomb-resistant walls, its own air supply and water tank, beds, showers to accommodate 30 people, and three backup generators. It also has rooms full of video monitors from where the mayor can oversee police and fire department responses. It is to be staffed around the clock and is intended as a meeting place for city leaders in the event of an act of terrorism. [CNN, 6/7/1999; London Times, 9/12/2001; Glanz and Lipton, 2004, pp. 233] The center is ridiculed as “Rudy’s bunker.” [Time, 12/22/2001] Author Philip Shenon will later comment that it “seemed the supreme example of how Giuliani’s ego and arrogance knew no bounds after four years in office,” and: “WABC Radio mocked Giuliani with a name-that-bunker contest for its listeners. Among the most popular entries: ‘Rudy’s Nuclear Winter Palace’ and ‘The Nut Shell.’” It is criticized because of the cost and because of the location, next to the WTC towers, one of the city’s top terrorist targets. In addition, the high floor it is on means it is vulnerable to power, water, and elevator outages. [Shenon, 2008, pp. 346-347] Most controversial is the 6,000-gallon fuel tank. In 1998 and 1999, Fire Department officials warn that the fuel tank violates city fire codes and poses a hazard. According to one Fire Department memorandum, if the tank were to catch fire it could produce “disaster.” Building 7 will be destroyed late in the day on 9/11; some suspect this tank helps explains why.

Major General Larry Arnold, the commander of the 1st Air Force whose mission includes the protection of the continental US against air attacks, tells the Associated Press that he is deeply worried by the possibility of an airborne terrorist attack. He says: “I lie awake worrying. It is one thing to put a truck inside the twin trade towers and blow it up. It is quite another to be able to fly a weapon across our borders. That is an attack, a direct attack, an unambiguous attack from outside our country.” In 1999, a study commissioned by Arnold emphasized the continued importance of the Air Force’s air sovereignty mission and the threat of terrorism (see 1999). [Associated Press, 2/1/2000; Associated Press, 8/2/2002; Filson, 2003, pp. 92] As one of the top commanders of NORAD, Arnold will play a pivotal role on the morning of 9/11 (see (8:42 a.m.) September 11, 2001, (10:08 a.m.-10:10 a.m.) September 11, 2001, and 10:31 a.m. September 11, 2001).

A FedEx MD-11 aircraft.A FedEx MD-11 aircraft. [Source: Alan Radecki]The North American Aerospace Defense Command (NORAD) practices scenarios based around suicidal pilots planning to deliberately crash stolen aircraft into the United Nations headquarters—a skyscraper in New York. The two scenarios are practiced on October 16 and October 23 as part of NORAD’s annual command post exercise called Vigilant Guardian. All of NORAD, including its Northeast Air Defense Sector based in Rome, New York, participates in this exercise. [US Congress. Senate. Committee on Armed Services, 8/17/2004; Arkin, 2005, pp. 545; GlobalSecurity (.org), 4/27/2005]
Simulation Involves Planned Suicide Plane Attack - General Richard Myers, currently the vice chairman of the Joint Chiefs of Staff, will later describe the scenario practiced on October 16: “Due to recent arrests involving illegal drug trafficking in Maine, an individual steals a Federal Express plane and plans a suicide attack into the United Nations building in New York City.” In response to the simulated crisis, exercise participants follow hijack checklists, exercise command and control, and coordinate with external agencies.
Simulation Involves WMD Directed at the UN - The October 23 scenario, according to Myers, is based around “[w]eapons of mass destruction directed at the United Nations. An individual steals a Federal Express aircraft and plans a suicide attack on the United Nations building in New York City.” In response, exercise participants practice command and control, and coordinate with external agencies, and fighter jets conduct an interception of the stolen aircraft. [US Congress. Senate. Committee on Armed Services, 8/17/2004] Federal Express currently flies mostly the DC-10 and the MD-11, which are both large jet planes, so presumably one of these kinds of aircraft is considered in the exercise scenarios. [Washington Post, 1/17/2001] The UN headquarters building—the target in the scenarios—is a 39-story high-rise, located just a few miles from the World Trade Center. [New York Daily News, 12/2/1999; Evening Standard, 9/11/2002]
Scenarios Revealed in 2004 - The details of these two scenarios will come to light in August 2004 during a hearing of the Senate Armed Services Committee. They will be revealed by Myers, at that time the chairman of the Joint Chiefs of Staff, after Senator Mark Dayton (D-MN) asks him, “Did NORAD conduct exercises or develop scenarios, prior to September 11, 2001, to test a military reaction to an aircraft hijacking which appeared destined to result in a suicide crash into a high-value target?” [US Congress. Senate. Committee on Armed Services, 8/17/2004] NORAD will state in 2004 that, until 9/11, it conducts four major exercises each year. Most of these include a hijack scenario, but not all of them involve planes being used as weapons. [USA Today, 4/18/2004; CNN, 4/19/2004] NORAD’s next Vigilant Guardian exercise, in 2001, will actually be several days underway on 9/11 (see (6:30 a.m.) September 11, 2001). It will include a number of scenarios based around plane hijackings, with the fictitious hijackers targeting New York in at least one of those scenarios (see September 6, 2001, September 9, 2001, September 10, 2001, and (9:40 a.m.) September 11, 2001).

Personnel at NORAD’s Northeast Air Defense Sector (NEADS) are briefed about the threat posed by Osama bin Laden. Lieutenant Colonel Mark Stuart, an intelligence officer at NEADS, will tell the 9/11 Commission that NORAD’s Continental United States Region has developed an “Osama bin Laden… threat briefing,” which is the last briefing of its kind before 9/11. The increased threat level relating to bin Laden and al-Qaeda is then “briefed at NEADS,” he will say. Further details of the briefing NEADS personnel receive are unstated. [9/11 Commission, 10/30/2003; 9/11 Commission, 10/30/2003 pdf file] NEADS, based in Rome, New York, is responsible for protecting the airspace in which the hijackings take place on September 11. It will therefore be responsible for coordinating the US military’s response to the hijackings. [9/11 Commission, 7/24/2004, pp. 17; Vanity Fair, 8/1/2006; Shenon, 2008, pp. 203]

Major General Larry Arnold, the commander of the Continental United States NORAD Region (CONR), struggles to maintain funding for a plan to defend against a cruise missile attack by terrorists. Arnold has long been worried by the US’s vulnerability to an airborne attack by terrorists (see 1999 and February 2000). But, as he will later recount, not everyone shares his concern. He will say: “Just two weeks before September 11, 2001, I had met with Vice Admiral Martin Mayer, the deputy commander in chief of Joint Forces Command located in Norfolk, Virginia. He had informed me that he intended to kill all funding for a plan my command had been working on for two years, that would defend against a cruise missile attack by terrorists. While I convinced Admiral Mayer to continue his funding support, he told me in front of my chief of staff, Colonel Alan Scott; Navy Captain David Stewart, the lead on the project; and my executive officer, Lt. Col. Kelley Duckett, that our concern about Osama bin Laden as a possible threat to America was unfounded and that, to repeat, ‘If everyone would just turn off CNN, there wouldn’t be a threat from Osama bin Laden.’” [Spencer, 2008, pp. 289]

Oklahoma City District Attorney Wes Lane announces that Oklahoma will continue prosecuting convicted Oklahoma City bombing conspirator Terry Nichols (see March 29, 1999) on 160 state charges of murder, in part because the state fears Nichols may win his federal appeals (see June 4, 1998). “I will not roll the dice on this issue. There is simply too much at stake,” Lane says. He says that the state will seek the death penalty against Nichols. Lane took over the case after District Attorney Robert Macy retired in June 2001; some have speculated that Oklahoma might drop the case due to the expenditure, the difficulty of finding an impartial jury, and the emotional toll on the victims of another trial. Nichols’s lead lawyer for the state case, Brian Hermanson, writes in a letter quoted by local newspapers that Nichols was willing to drop his appeals and accept a federal life sentence to avoid a state trial. The letter states: “Taking such a step ensures that he will spend the rest of his life in prison. It would enable Mr. Lane to drop the state prosecution, thereby sparing Oklahoma the trauma and expense of another trial.” Lane responds that “the interests of the people of the State of Oklahoma cannot be vindicated by the blind reliance on the federal government or Terry Lynn Nichols,” and says he will seek sanctions against Hermanson for what he calls a “glaring, blatant violation” of a state court order not to discuss the case. Shelly Thompson, who lost her mother in the blast (see 8:35 a.m. - 9:02 a.m. April 19, 1995), says: “You can’t just get away with a little bit of a crime. We’re going to go for the whole thing. I want to make sure he will stay in prison for his life. This is something I need to do for her. He was not found guilty in my mother’s death and 159 other deaths. They are more than numbers.” [New York Times, 9/6/2001; The Oklahoman, 4/2009; Mayhem (.net), 4/2009]

The North American Aerospace Defense Command (NORAD) practices for dealing with the simulated hijackings of two commercial aircraft by terrorists, as part of its annual training exercise called Vigilant Guardian. Whether the simulated hijackings take place simultaneously or at different times of the day is unclear. [9/11 Commission, 2004; Spencer, 2008, pp. 3]
Terrorists Threaten to 'Rain Terror from the Skies' - One of the two exercise scenarios involves the hijacking of a Boeing 747 bound from Tokyo, Japan, to Anchorage, Alaska. According to a document later produced by the 9/11 Commission, the scenario involves the “[t]hreat of harm to [the plane’s] passengers and possibly [a] large population within [the] US or Canada.” It includes what is apparently a fictitious Asian terrorist group called “Mum Hykro,” which is threatening to “rain terror from the skies onto a major US city unless the US declares withdrawal from Asian conflict.” During the hijacking scenario, some of the plane’s passengers are killed. The plane’s course is changed to take it to Vancouver, Canada, and then to San Francisco, California. In response to the hijacking, the chairman of the Joint Chiefs of Staff and FAA headquarters direct military assistance, in the form of “covert shadowing” of the hijacked aircraft. NORAD has to liaise with the appropriate air traffic control centers. Its Alaskan region (ANR) and its Canadian region (CANR) participate in the scenario.
Group Threatens to Blow up Plane - In the other hijacking scenario, 10 members of another fictitious terrorist group, “Lin Po,” seize control of a Boeing 747 bound from Seoul, South Korea, to Anchorage. The hijackers have weapons on board that were smuggled onto the plane in small tote bags by ground crew members prior to takeoff. Gas containers were also smuggled onto the aircraft by baggage handlers before takeoff. Arming devices are attached to these containers, which can be remotely detonated. The terrorist group issues demands and threatens to blow up the plane if these are not met. The CIA and NSA caution that the group has the means and motivation to carry out a chemical and biological attack. The group kills two of the plane’s passengers and threatens to use the gas it has on board in some manner. In response to the simulated hijacking, NORAD directs fighter jets to get in a position to shoot down the hijacked airliner, and orders ANR to intercept and shadow it. In the scenario, the 747 eventually lands in Seattle, Washington. [9/11 Commission, 2004]
Most NORAD Exercises Include Hijack Scenario - Vigilant Guardian is one of four major exercises that NORAD conducts each year. Most of these exercises include a hijack scenario. [USA Today, 4/18/2004] Ken Merchant, NORAD’s joint exercise design manager, will tell the 9/11 Commission in 2003 that he cannot “remember a time in the last 33 years when NORAD has not run a hijack exercise.” [9/11 Commission, 11/14/2003 pdf file] This year’s Vigilant Guardian will include additional aircraft hijacking scenarios on September 9 and September 10 (see September 9, 2001 and September 10, 2001), and a further simulated plane hijacking is scheduled for the morning of September 11 (see (9:40 a.m.) September 11, 2001).

Most State Emergency Managers in Attendance - Conference attendees include around 350 government and industry emergency specialists. [New York Times, 9/12/2001; State Government News, 10/2001 pdf file] Among them are almost all of America’s state emergency management directors and most of the senior FEMA staff. [Stateline (.org), 9/13/2001] They are there, reportedly, “to hear briefings on the latest issues in domestic preparedness, improve state and local capabilities, address energy shortages, and discuss lessons from the February 2001 Nisqually earthquake.” [State Government News, 10/2001 pdf file] The attendees discuss anti-terrorism planning courses, and the status of federal aid and cooperation efforts. [Stateline (.org), 9/10/2002] Allbaugh is the event’s keynote speaker and gives his talk on September 10, in which he describes his focus on improving emergency capabilities and preparing for disaster. [New York Times, 9/12/2001; State Government News, 10/2001 pdf file]
Conference Ends Early Due to Attacks - The NEMA conference is originally scheduled to run until September 12. [Natural Hazards Observer, 3/2001; National Emergency Management Association, 8/15/2001] But because of the terrorist attacks on September 11, it ends a day early (see After 8:46 a.m. September 11, 2001). [119th Fighter Wing, 10/25/2001] Special arrangements are then made for some of the emergency managers in attendance to be flown home on military aircraft, while others have to drive long distances back to their states (see (After 11:00 a.m.) September 11, 2001, (After 11:00 a.m.) September 11, 2001, and (After 4:30 p.m.) September 11, 2001). [Stateline (.org), 9/13/2001; State Government News, 10/2001 pdf file]
Timing of Attacks Inconvenient - In May this year, President Bush put FEMA in charge of responding to any terrorist attacks in the United States, charging it with creating an Office of National Preparedness to coordinate the government’s response to such attacks (see May 8, 2001). [White House, 5/8/2001; Los Angeles Times, 5/9/2001] Following the attacks on September 11, FEMA spokesman Mark Wolfson will note the inconvenience of these attacks occurring at the same time as the NEMA conference. He will say that FEMA officials do not know whether the attacks were timed to catch emergency officials off guard, but “it is something that law enforcement investigators might be looking at.” [Stateline (.org), 9/13/2001] NEMA is the professional association of state emergency management directors.

The North American Aerospace Defense Command (NORAD) commences Northern Vigilance, a military operation that involves it deploying fighter jets to Alaska and Northern Canada to monitor a Russian Air Force training exercise. The Russian exercise is scheduled to take place over the North Atlantic, Pacific, and Arctic Oceans from September 10 to September 14 (see September 10, 2001), and the NORAD fighters are set to stay in Alaska and Northern Canada until it ends. [BBC, 2001, pp. 161; North American Aerospace Defense Command, 9/9/2001; Washington Times, 9/11/2001] As well as conducting this operation, NORAD is currently running a major exercise called Vigilant Guardian, which “postulated a bomber attack from the former Soviet Union,” according to the 9/11 Commission Report (see September 10, 2001, (6:30 a.m.) September 11, 2001, and (8:00 a.m.) September 11, 2001). [9/11 Commission, 2004; 9/11 Commission, 3/1/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 458] The Russians will cancel their exercise on the morning of September 11 in response to the terrorist attacks in the United States (see (After 10:03 a.m.) September11, 2001), when they “knew NORAD would have its hands full,” according to the Toronto Star. [Toronto Star, 12/9/2001; Defense Video and Imagery Distribution System, 9/8/2011] It is unknown from which bases NORAD sends fighters for Northern Vigilance and how many US military personnel are involved. However, in December 2000, it took similar action—called Operation Northern Denial—in response to a “smaller scale” Russian “long-range aviation activity in northern Russia and the Arctic.” More than 350 American and Canadian military personnel were involved on that occasion.

[Source: Airman]Fighter jets that are scrambled by the North American Aerospace Defense Command (NORAD) in response to suspicious or unidentified aircraft in US airspace are able to take off within minutes of receiving a scramble order, in the years preceding 9/11. [Airman, 1/1996; Cape Cod Times, 9/15/2001; Spencer, 2008, pp. 117] NORAD keeps a pair of fighters on “alert” at a number of sites around the US. These fighters are armed and fueled, ready for takeoff. [American Defender, 4/1998; Air Force Magazine, 2/2002; Bergen Record, 12/5/2003] Even before 9/11, the fighters are regularly scrambled to intercept errant aircraft (see 1990-2001). [General Accounting Office, 5/3/1994, pp. 4; Associated Press, 8/14/2002]
Pilots Stay Close to Their Aircraft - Pilots on alert duty live near to their fighters, so they will be ready for a prompt takeoff if required. Author Lynn Spencer will write that pilots on alert duty at Langley Air Force Base in Virginia “live, eat, and sleep just steps from jets.” [Spencer, 2008, pp. 117] According to Major Martin Richard, a pilot with the 102nd Fighter Wing at Otis Air National Guard Base in Massachusetts, “Every day” at his base, “365 days a year, 24 hours a day, at least two fighter pilots and four maintenance personnel ate, slept, and lived nestled adjacent to three fully loaded F-15 jets.” [Richard, 2010, pp. 8]
Fighters Can Get Airborne in Minutes - The fighters on alert are required to be in the air within minutes of a scramble order. General Ralph Eberhart, the commander of NORAD on 9/11, will tell the 9/11 Commission that they “have to be airborne in 15 minutes.” [9/11 Commission, 6/17/2004] Richard will write that the objective of the alert pilots at his base is “to be airborne in 10 minutes or less if the ‘horn’ went off.” [Richard, 2010, pp. 8] According to other accounts, fighters on alert are generally airborne in less than five minutes. Airman magazine reports in 1996 that NORAD’s alert units “work around the clock, and usually have five minutes or less to scramble when the warning klaxon sounds.” [Airman, 1/1996] A few days after 9/11, the Cape Cod Times will report that, “if needed,” the fighters on alert at Otis Air Base “must be in the air within five minutes.” [Cape Cod Times, 9/15/2001] According to Spencer, pilots on alert duty at Langley Air Force Base are “always just five minutes away from rolling out of the hangars in their armed fighters.” [Spencer, 2008, pp. 117] Captain Tom Herring, a full-time alert pilot at Homestead Air Reserve Base in Florida, says in 1999, “If needed, we could be killing things in five minutes or less.” [Airman, 12/1999] In 1994, NORAD is planning to reduce the number of alert sites in the continental United States and, according to a report published that year by the General Accounting Office, “Each alert site will have two fighters, and their crews will be on 24-hour duty and ready to scramble within five minutes.” [General Accounting Office, 5/3/1994, pp. 16]
'Everything Else Just Stops' following Scramble Order - Once an order to scramble is received, alert pilots try to get airborne as quickly as they can. According to Richard, being a pilot sitting on alert is “akin to being a fireman.” Richard will later recall that when the horn goes off, signaling for him to get airborne, “no matter where I was or what I was doing, I had to swiftly don my anti-g suit, parachute harness, and helmet, run to the jet where my maintenance crew was waiting, fire up the powerful jet engines, and check all of the systems while simultaneously talking with the Otis command post who had a direct feed from NEADS [NORAD’s Northeast Air Defense Sector]. When the horn blew, a frantic, harrowing race into a high pressure situation ensued.” [Richard, 2010, pp. 8] Herring says: “We go full speed when that klaxon sounds and people know not to get in front of us, because we take scrambles very seriously.… We’re fired up about what we do and we’re the best at what we do.” [Airman, 12/1999] Technical Sergeant Don Roseen, who keeps the alert fighters at Tyndall Air Force Base in Florida ready for instant takeoff, says in 1999 that these fighters are “hot and cocked, they are ready.” Roseen says that when the klaxon goes off, “everything else just stops.”
Suspicious Aircraft 'Could Be a Terrorist' - When they are taking off, pilots may be unaware exactly why they are being scrambled. Major Steve Saari, an alert pilot at Tyndall Air Force Base, says: “There are several different things you could run into and you don’t know until you’re airborne. And sometimes you can’t tell until you have a visual identification.” Saari says: “The unknown [aircraft] could be something as simple as a lost civilian or it could be somebody defecting from Cuba. It could be a terrorist or anything in-between.” [American Defender, 3/1999] According to Airman magazine, the unidentified aircraft might be “Cuban MiGs, drug traffickers, smugglers, hijackers, novice pilots who’ve filed faulty flight plans, or crippled aircraft limping in on a wing and a prayer.” [Airman, 12/1999]
Intercepted Aircraft Could Be Shot Down - Fighters can respond in a number of ways when they intercept a suspect aircraft. In 2011, Jeff Ford—at that time the aviation and security coordinator for the NORAD and USNORTHCOM Interagency Coordination Directorate—will say that before 9/11, scrambled fighters can “intercept the aircraft, come up beside it, and divert it in the right direction toward an airfield or find out what the problems are in order to assist.” [Defense Video and Imagery Distribution System, 9/8/2011] According to MSNBC: “[I]nterceptors can fly alongside a plane to see who’s flying it. They can also try to force it off course. Once it is apparent that it is not following directions, it might be forced over the ocean or to a remote airport—or even shot down.” [MSNBC, 9/12/2001] On September 11, 2001, NEADS will scramble fighters that are kept on alert in response to the hijackings (see 8:46 a.m. September 11, 2001 and 9:24 a.m. September 11, 2001).

Exercise Includes Simulated Hijacking - Vanity Fair reports that the “day’s exercise” (presumably Vigilant Guardian) is “designed to run a range of scenarios, including a ‘traditional’ simulated hijack in which politically motivated perpetrators commandeer an aircraft, land on a Cuba-like island, and seek asylum.” [Vanity Fair, 8/1/2006] However, at NEADS, most of the dozen or so staff on the operations floor have no idea what the exercise is going to entail and are ready for anything. [Utica Observer-Dispatch, 8/5/2004]
NORAD Fully Staffed and Alert - NORAD is currently running a real-world operation named Operation Northern Vigilance (see September 9, 2001). It may also be conducting a field training exercise calling Amalgam Warrior on this morning (see 9:28 a.m. September 11, 2001). NORAD is thus fully staffed and alert, and senior officers are manning stations throughout the US. The entire chain of command will be in place and ready when the first hijacking is reported. An article later says, “In retrospect, the exercise would prove to be a serendipitous enabler of a rapid military response to terrorist attacks on September 11.” [Aviation Week and Space Technology, 6/3/2002; Bergen Record, 12/5/2003] Colonel Robert Marr, in charge of NEADS, will say: “We had the fighters with a little more gas on board. A few more weapons on board.” [ABC News, 9/11/2002] However, Deskins and other NORAD officials later are initially confused about whether the 9/11 attacks are real or part of the exercise (see (8:38 a.m.-8:43 a.m.) September 11, 2001).

The last routine communication takes place between air traffic control and the pilots of Flight 11 at 8:13 and 29 seconds. Boston Center air traffic controller Pete Zalewski is handling the flight, and instructs it to turn 20 degrees to the right. Pilot John Ogonowski immediately acknowledges the instruction, but seconds later he fails to respond to a command to climb to 35,000 feet. Zalewski repeatedly tries to reach the pilot over the next ten minutes, even using the emergency frequency, but gets no response (see 8:14 a.m.-8:24 a.m. September 11, 2001). The 9/11 Commission concludes that Flight 11 is hijacked at 8:14, or shortly afterwards (see 8:14 a.m. September 11, 2001).

After Flight 11 fails to respond to an instruction from air traffic control to climb to 35,000 feet (see 8:13 a.m. September 11, 2001), the controller handling it, Pete Zalewski, tries to regain contact with the aircraft. Over the following ten minutes, he makes numerous attempts but without success. (Zalewski says he makes 12 attempts; the 9/11 Commission says nine.) He tries reaching the pilot on the emergency frequency. Zalewski later recalls that initially, “I was just thinking that it was, you know, maybe they—pilots weren’t paying attention, or there’s something wrong with the frequency.… And at first it was pretty much, you know, ‘American 11,’ you know, ‘are you paying attention? Are you listening?’ And there was still no response.” He says, “I went back to the previous sector to see if the pilot had accidentally flipped the switch back over on the—on the radio.” But as Zalewski is repeatedly unable to get any response from Flight 11, he recalls, “I even began to get more concerned.” However, Zalewski claims, it is not until he sees the plane’s transponder go off at around 8:21 that he suspects something is “seriously wrong,” and calls his supervisor for assistance (see (8:21 a.m.) September 11, 2001). And it is not until about 8:25 that he realizes for sure that he is dealing with a hijacking (see (8:25 a.m.) September 11, 2001).

Zalewski later claims he turns to his supervisor and says, “Would you please come over here? I think something is seriously wrong with this plane. I don’t know what. It’s either mechanical, electrical, I think, but I’m not sure.” When asked if he suspected a hijacking at this point, he replies, “Absolutely not. No way.” According to the 9/11 Commission, “the supervisor instructed the controller [presumably Zalewski] to follow standard operating procedures for handling a ‘no radio’ aircraft once the controller told the supervisor the transponder had been turned off.” Another flight controller, Tom Roberts, has another nearby American Airlines Flight try to contact Flight 11. There is still no response. The flight is now “drastically off course” but NORAD is still not notified. [MSNBC, 9/11/2002; 9/11 Commission, 6/17/2004] Note that this response contradicts flight control manager Glenn Michael’s assertion that Flight 11 was considered a possible hijacking as soon as the transponder was discovered turned off.

American Airlines has problems contacting the FAA’s Command Center in Herndon, Virginia, about the problems with its aircraft, according to four managers working at the airline’s System Operations Control (SOC) center in Fort Worth, Texas, on this day. Craig Marquis, Craig Parfitt, Joe Bertapelle, and Mike Mulcahy will later tell the 9/11 Commission that American Airlines has “a hard time on 9/11 in getting in touch with Herndon.” They will say that “[p]recious minutes were lost in building the communications bridge” between the SOC and the Command Center. The cause of these communication problems is unknown. [9/11 Commission, 11/19/2003 pdf file] The SOC has known that there are problems on Flight 11 since 8:21 a.m., when Marquis received a call from a supervisor at the airline’s Southeastern Reservations Office in North Carolina, alerting him to a call that had been received from one of the plane’s flight attendants about the emergency taking place (see 8:21 a.m. September 11, 2001). Presumably the SOC starts trying to contact the FAA Command Center soon after receiving this call. It is known that the SOC will make contact with the Command Center at 9:16 a.m., if not earlier (see 9:16 a.m.-9:18 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 9, 15] Bill Halleck, an air traffic control specialist at the SOC, is at least able to reach the FAA’s Boston Center regarding Flight 11 at 8:29 a.m. (see 8:29 a.m. September 11, 2001).

[Source: NBC]Because the talkback button on Flight 11 has been activated, Boston Center air traffic controllers can hear a hijacker on board say to the passengers: “We have some planes. Just stay quiet and you’ll be OK. We are returning to the airport.” [Boston Globe, 11/23/2001; 9/11 Commission, 7/24/2004, pp. 19] Air traffic controller Pete Zalewski recognizes this as a foreign, Middle Eastern-sounding voice, but does not make out the specific words “we have some planes.” He responds, “Who’s trying to call me?” Seconds later, in the next transmission, the hijacker continues: “Nobody move. Everything will be OK. If you try to make any moves you’ll endanger yourself and the airplane. Just stay quiet.” [New York Times, 10/16/2001; 9/11 Commission, 6/17/2004; MSNBC, 9/9/2006] Bill Peacock, the FAA director of air traffic services, later claims, “We didn’t know where the transmission came from, what was said and who said it.” David Canoles, the FAA’s manager of air traffic evaluations and investigations, adds: “The broadcast wasn’t attributed to a flight. Nobody gave a flight number.” [Washington Times, 9/11/2002] Similarly, an early FAA report will state that both these transmissions came from “an unknown origin.” [Federal Aviation Administration, 9/17/2001 pdf file] Zalewski asks for an assistant to help listen to the transmissions coming from the plane, and puts its frequency on speakers so others at Boston Center can hear. Because Zalewski didn’t understand the initial hijacker communication from Flight 11, the manager of Boston Center instructs the center’s quality assurance specialist to “pull the tape” of the transmission, listen to it carefully, and then report back. They do this, and by about 9:03 a.m. a Boston manager will report having deciphered what was said in the first hijacker transmission (see 9:03 a.m. September 11, 2001). [9/11 Commission, 6/17/2004; MSNBC, 9/9/2006] Fellow Boston controller Don Jeffroy also hears the tape of the hijacker transmissions, though he doesn’t state at what time. He says: “I heard exactly what Pete [Zalewski] heard. And we had to actually listen to it a couple of times just to make sure that we were hearing what we heard.” [MSNBC, 9/11/2002] At some point, Ben Sliney, the national operations manager at the FAA’s Herndon Command Center, gets word of the “We have some planes” message, and later says the phrase haunts him all morning. American Airlines Executive Vice President for Operations Gerard Arpey is also informed of the “strange transmissions from Flight 11” at some point prior to when it crashes at 8:46 a.m. [USA Today, 8/12/2002] Boston Center will receive a third transmission from Flight 11 about ten minutes later (see (8:34 a.m.) September 11, 2001).

According to Terry Biggio, the operations manager at the FAA’s Boston Center, the center initially thought Flight 11 “was a catastrophic electrical failure and… was diverting to New York” (see (8:21 a.m.) September 11, 2001). [Federal Aviation Administration, 10/19/2002] However, at about 8:24 a.m., controllers heard two radio transmissions from it, with the voice of a hijacker declaring, “We have some planes” (see 8:24 a.m. September 11, 2001). Pete Zalewski, who is handling Flight 11, says that after the second of these: “I immediately knew something was very wrong. And I knew it was a hijack.” He alerts his supervisor. Lino Martins, another Boston air traffic controller, says, “the supervisor came over, and that’s when we realized something was serious.” [Christian Science Monitor, 9/13/2001; MSNBC, 9/11/2002; 9/11 Commission, 6/17/2004] However, two senior FAA officials—Bill Peacock and David Canoles—later say that the hijacker transmissions were not attributed to a flight, so controllers didn’t know their origin. [Washington Times, 9/11/2002] An early FAA report will similarly refer to them as having come “from an unknown origin.” But right away, the center begins notifying the chain of command that a suspected hijacking is taking place (see 8:25 a.m. September 11, 2001). [Federal Aviation Administration, 9/17/2001 pdf file] However, some reports claim that controllers decided Flight 11 was probably hijacked earlier than this, by about 8:20 a.m. (see (8:20 a.m.) September 11, 2001).

At 8:26, Flight 11, which is already way off course, makes an unplanned 100-degree turn to the south over Albany, New York. A minute later, it turns right, to the south-southwest. Then, two minutes on, at 8:29, it turns left to the south-southeast. Boston air traffic controllers never lose sight of the flight, though they can no longer determine altitude as the transponder is turned off. Its last known altitude was 29,000 feet. [Christian Science Monitor, 9/13/2001; Federal Aviation Administration, 9/17/2001 pdf file; National Transportation Safety Board, 2/19/2002 pdf file; MSNBC, 9/11/2002] Before this turn, the FAA had tagged Flight 11’s radar dot for easy visibility and, at American Airlines’ System Operations Control (SOC) in Fort Worth, Texas, “All eyes watched as the plane headed south. On the screen, the plane showed a squiggly line after its turn near Albany, then it straightened.” [Wall Street Journal, 10/15/2001] Boston air traffic controller Mark Hodgkins later says, “I watched the target of American 11 the whole way down.” [ABC News, 9/6/2002] However, apparently, NORAD’s Northeast Air Defense Sector (NEADS) has different radar. When they are finally told about the flight, they cannot find it (see Shortly After 8:37 a.m. September 11, 2001). NEADS has to repeatedly phone the FAA, airlines, and others, for clues as to the plane’s location. NEADS will eventually focus on a radar blip they believe might be Flight 11, and watch it close in on New York.

National Operations Manager Learns of Hijacking - A supervisor at the Command Center promptly passes on the news of the possible hijacking to Ben Sliney, who is on his first day as the national operations manager there. The supervisor says the plane in question is “American Flight 11—a 767 out of Boston for Los Angeles.” According to author Lynn Spencer, “Sliney flashes back to the routine for dealing with hijackings from the days when they were more common.” The procedure is to “[k]eep other aircraft away from the errant plane. Give the pilots what they need. The plane will land somewhere, passengers will be traded for fuel, and difficult negotiations with authorities will begin. The incident should resolve itself peacefully, although the ones in the Middle East, he recalls, often had a more violent outcome.” Apparently not expecting anything worse to happen, Sliney continues to the conference room for the daily 8:30 staff meeting there (see 8:30 a.m.-8:40 a.m. September 11, 2001).
Command Center a 'Communications Powerhouse' - The FAA Command Center is located in Herndon, Virginia, 25 miles from Washington, DC. According to Spencer, it “is a communications powerhouse, modeled after NASA’s Mission Control. The operations floor is 50 feet wide and 120 feet long, packed with tiered rows of computer stations, and at the front, seven enormous display screens show flight trajectories and weather patterns.” The center has nearly 50 specialists working around the clock, planning and monitoring the flow of air traffic over the United States. These specialists work with airlines and air traffic control facilities to fix congestion problems and deal with weather systems. [Spencer, 2008, pp. 1 and 19-20]

This call is American Airlines’ first contact with FAA controllers regarding Flight 11. [9/11 Commission, 3/25/2004, pp. 15; 9/11 Commission, 4/26/2004; 9/11 Commission, 4/26/2004 pdf file]

Marquis had replied that he would get in touch with air traffic control about this. [9/11 Commission, 8/26/2004, pp. 9] He asked Halleck to contact the FAA’s Boston Center and find out what is happening with Flight 11. Immediately after receiving this request, Halleck calls the traffic management unit (TMU) at the Boston Center. [9/11 Commission, 1/8/2004 pdf file; 9/11 Commission, 4/26/2004 pdf file]
Boston Center Tells Halleck Details of Crisis - When the call is answered, Halleck introduces himself and then says, “[W]e’re trying to find out the status to what you know about our Flight 11.” The Boston Center controller replies that Flight 11’s last reported altitude was below 29,000 feet. He reports that the flight has altered course, saying, “He was heading west, but right now he’s pointed southwest of Albany.” Furthermore, he says, “we lost frequency with him,” meaning communication has been lost with the plane, and adds that the plane’s transponder has been turned off.
Controller Heard a 'Threat in the Background' on Flight 11 - The controller at the TMU also tells Halleck that the Boston Center controller dealing with Flight 11 “heard on the frequency a threat in the background, but that’s unconfirmed and we’re trying to pull the tape [recording of the radio communication] at this time.” Halleck asks for clarification that the controller handling Flight 11 “heard a background noise in the cockpit,” and is told: “Like a threat. Yes, sir.” The controller at the TMU adds that he has been told that it is believed the pilot’s microphone on Flight 11 was keyed, and so the controller handling the flight “heard in the background, like, yeah, ‘Return to an airport… or I’ll kill you,’ or something to that effect.” He also says the plane is not squawking any emergency transponder codes. Halleck says he is tracking Flight 11 on the aircraft situation display, and the controller replies that the Boston Center is currently tracking the plane with primary radar only. The controller ends by telling Halleck, “That is all we have.” [American Airlines, 9/11/2001, pp. 56-57; American Airlines, 9/11/2001, pp. 58; 9/11 Commission, 1/8/2004 pdf file]

[United States District Court for the Southern District of New York, 1/16/2009 pdf file] Halleck will promptly pass on the information from the Boston Center to Marquis, and this will lead American Airlines to suspect that Flight 11 has been hijacked (see 8:33 a.m. September 11, 2001).

[Filson, 2003, pp. 47; Spencer, 2008, pp. 22] Otis Air Base, at Cape Cod, Massachusetts, is one of NORAD’s seven alert sites in the continental United States, which keeps two armed fighter jets ready for immediate takeoff.

Supervisor Calls Otis, Violating Protocol - Bueno calls the control tower at Otis even though, according to author Lynn Spencer, he “knows it’s not standard operating procedure to call the military directly—that’s supposed to be done by FAA headquarters.” But he has “checked the FAA regulation manual, and in the back under section FAAO 7610.4J, Appendix 16, it states that fighters can be launched directly at FAA request, so he is going to make that happen. He may not be FAA headquarters, but he is FAA!” [Spencer, 2008, pp. 22]
Bueno Requests Fighters, Told to Call NEADS - Bueno tells the controller at the Otis tower that Flight 11 has lost its identification signal and appears to be headed toward Manhattan; it looks like a possible hijacking, and fighter jets are needed, fast. [Filson, 2003, pp. 47] But the controller tells Bueno that he must follow the protocol, which is to contact NORAD’s Northeast Air Defense Sector (NEADS). The controller says: “You’ve got to go through the proper channels. They’re the only ones with the authority to initiate a scramble order.” [Spencer, 2008, pp. 22] Bueno asks the controller for the telephone number for NEADS. [102nd Fighter Wing, 2001] Following this call, the tower controller will contact the Otis Air Base operations desk, to let it know that it might be receiving a call from NEADS (see (Between 8:31 a.m. and 8:40 a.m.) September 11, 2001). [Spencer, 2008, pp. 27]
Otis Pilots Critical of Bueno - The two alert pilots at Otis Air Base will later criticize Bueno for calling the base directly. One of them, Major Daniel Nash, will complain: “It sounds like the FAA didn’t have their [act] together at all when they were calling the [Otis] tower.… To me, it sounded like there was someone who didn’t know what they were doing.” [Boston Globe, 9/11/2005] Lieutenant Colonel Timothy Duffy, the other alert pilot, will comment: “It didn’t happen the way it was supposed to.… We were the ones who were contacted right away and knew about it before the air defense sector.” [Filson, 2003, pp. 50]
Time of Call Unclear - Bueno also calls the FAA’s Cape Terminal Radar Approach Control (TRACON), which is located on Otis Air Base, at 8:34 a.m. and requests that fighters be launched from Otis (see 8:34 a.m. September 11, 2001). [Federal Aviation Administration, 4/19/2002; 9/11 Commission, 9/22/2003 pdf file] Whether he makes that call before or after he calls the Otis tower is unstated. According to the 9/11 Commission Report, “the first notification received by the military—at any level—that American 11 had been hijacked” is when the FAA’s Boston Center calls NEADS just before 8:38 a.m. (see (8:37 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] If that is correct, it would indicate that Bueno calls the Otis tower after he calls the Cape TRACON.

Lieutenant Colonel Timothy Duffy.Lieutenant Colonel Timothy Duffy. [Source: CBC]After being informed of the possible hijacking of Flight 11, an air traffic controller in the control tower at Otis Air National Guard Base calls the base’s operations desk to let it know that it might be receiving a call from NORAD’s Northeast Air Defense Sector (NEADS). [Spencer, 2008, pp. 27-28] Daniel Bueno, a supervisor at the FAA’s Boston Center, has just called the control tower at Otis Air Base, at Cape Cod, Massachusetts, alerting it to the problems with Flight 11 and requesting military assistance. The controller who took the call told Bueno he needed to call NEADS in order to get fighter jets launched (see (Between 8:30 a.m. and 8:40 a.m.) September 11, 2001). [Filson, 2003, pp. 47; Spencer, 2008, pp. 22]
Tower Controller Calls Operations Desk - According to author Lynn Spencer, the tower controller subsequently “figures a call [to Otis Air Base] will be coming from NEADS soon and a scramble order is likely. He knows the fighter pilots will appreciate the heads-up.” He therefore calls the Otis Air Base operations desk. According to Spencer, the phone is answered by Master Sergeant Mark Rose, who is the superintendent of aviation management, in charge of flight records and currency for the pilots of the 102nd Fighter Wing. [Spencer, 2008, pp. 27] But according to the 102nd Fighter Wing’s own history of the 9/11 attacks, the call is answered by a Technical Sergeant “Margie Woody.” [102nd Fighter Wing, 2001]
Controller Confuses Superintendent - Rose (or Woody, if the wing’s account is correct) is initially confused by the call. The tower controller does not identify himself or say where he is calling from, but instead begins by asking, “What do you have available?” As Spencer will describe, “For all [Rose] knows, this could be a wrong number or a crank call,” so rather than giving information about the base, Rose responds, “What are you talking about?” The controller then identifies himself and explains that he has just received a report about a hijacking. Rose realizes he needs to pass the call on to someone more appropriate.
Pilot Informed of Hijacking - Pilot Lieutenant Colonel Timothy Duffy, who is the director of operations for the 102nd Fighter Wing, is standing next to Rose by the operations desk. Rose tells him, “Duff, you got a phone call,” and then says the caller is “Otis tower—something about an apparent hijacking under way: American 11, a 767, out of Boston and headed for California.” [Spencer, 2008, pp. 27-28] Duffy will later recall his response to this news: “As soon as we heard there was something about a hijacking we got moving.” [Filson, 2003, pp. 50] On his handheld radio he calls Major Daniel Nash, who along with Duffy is an “alert” pilot on duty at this time, and instructs him to suit up ready for any scramble call. [Spencer, 2008, pp. 28] The two pilots will run to the nearby locker room, put on their G-suits and helmets, and then head out toward their jets (see (8:40 a.m.) September 11, 2001). [Cape Cod Times, 8/21/2002; Boston Globe, 9/11/2005] Meanwhile, a commander at Otis will phone NEADS to report the FAA’s request for military assistance (see Shortly After 8:37 a.m. September 11, 2001).
Call Is Not 'the First Notification Received by the Military' - The exact time the tower controller calls the operations desk at is unclear. Duffy will later guess that the call occurs “at about 8:30, 8:35.” [Filson, 10/22/2002; Filson, 2003, pp. 50] But according to the 9/11 Commission Report, “the first notification received by the military—at any level—that American 11 had been hijacked” is when the FAA’s Boston Center calls NEADS just before 8:38 a.m. (see (8:37 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] According to the102nd Fighter Wing’s history of the 9/11 attacks, the call to the operations desk is made at 8:38 a.m. [102nd Fighter Wing, 2001] Bueno also called the FAA’s Cape Terminal Radar Approach Control (TRACON), which is located on Otis Air Base, at 8:34 a.m., to request that fighters be launched from Otis (see 8:34 a.m. September 11, 2001), and in response, the TRACON contacts the Otis tower and operations desk (see (8:36 a.m.-8:41) September 11, 2001).

FAA headquarters in Washington, DC.FAA headquarters in Washington, DC. [Source: FAA]Four minutes after it is informed of the suspected hijacking of Flight 11 (see 8:28 a.m. September 11, 2001), the FAA Command Center in Herndon, Virginia, passes on word of the hijacking to the operations center at FAA headquarters in Washington, DC. The headquarters is apparently already aware of the hijacking, as the duty officer who speaks with the Command Center responds that security personnel at the headquarters have just been discussing it on a conference call with the FAA’s New England regional office. [9/11 Commission, 7/24/2004, pp. 19; 9/11 Commission, 8/26/2004, pp. 11] According to the 9/11 Commission, “FAA headquarters is ultimately responsible for the management of the national airspace system,” and the operations center there “receives notifications of incidents, including accidents and hijackings.” FAA headquarters has a hijack coordinator, who is “the director of the FAA Office of Civil Aviation Security or his or her designate.” Procedures require that, if a hijacking is confirmed, the hijack coordinator on duty is “to contact the Pentagon’s National Military Command Center (NMCC) and to ask for a military escort aircraft to follow the flight, report anything unusual, and aid search and rescue in the event of an emergency.” Yet, the Commission will state, although “FAA headquarters began to follow the hijack protocol,” it does “not contact the NMCC to request a fighter escort.” [9/11 Commission, 7/24/2004, pp. 16-19] Mike Canavan, who would normally be the FAA’s hijack coordinator, is away in Puerto Rico this morning, and it is unclear who—if anyone—is standing in for him in this critical role (see 8:30 a.m. September 11, 2001).

Craig Marquis, the manager on duty at the American Airlines System Operations Control (SOC) center in Fort Worth, Texas, is told details of the crisis with Flight 11 that have just been received from the FAA’s Boston Center, and this information leads American Airlines to suspect that Flight 11 has been hijacked. [9/11 Commission, 8/26/2004, pp. 12] Minutes earlier, Marquis instructed Bill Halleck, an air traffic control specialist at the SOC, to contact the Boston Center to find out what was happening with Flight 11, and Halleck has just done so (see 8:29 a.m. September 11, 2001). [9/11 Commission, 1/8/2004 pdf file; 9/11 Commission, 4/26/2004 pdf file] Halleck now calls Marquis and tells him what he learned about Flight 11 from his call with the Boston Center. He says the aircraft is at “29,000 feet. They’ve lost comm [communications] with ‘em. Turned off his transponder. Tracking his primary [radar track] only. Was westbound. Turned southbound. Said the controller heard on the [radio] frequency, the pilot apparently adjust his mike… lot of loud voices… that sounded threatening.” Halleck then tells Marquis the details of this possible threat in the cockpit of Flight 11 that the Boston Center heard over radio. He says, “Something about ‘return or I’ll kill ya,’ or something to that effect… or threatening dialogue.” Halleck adds that he asked the Boston Center to pass on to the SOC “any information or updates” it subsequently receives. After Marquis hears this information from Halleck, he asks Halleck to “pull” Flight 11 up on his aircraft situation display. Following Halleck’s report to Marquis, American Airlines “now suspected that Flight 11 had been hijacked,” according to the 9/11 Commission.

Cape TRACON.Cape TRACON. [Source: FAA]Daniel Bueno, a supervisor at the FAA’s Boston Center, contacts the FAA’s Cape Terminal Radar Approach Control (TRACON), located on Otis Air National Guard Base at Cape Cod, Massachusetts, to alert it to the possible hijacking of Flight 11 and request that it arrange for military assistance in response. [Federal Aviation Administration, 9/17/2001 pdf file; Federal Aviation Administration, 4/19/2002; 9/11 Commission, 2004; 9/11 Commission, 7/24/2004, pp. 20]
Bueno Requests Fighters - After his call is initially answered by an air traffic controller at the Cape TRACON, Bueno is quickly passed on to Tim Spence, an operational supervisor at the facility. Bueno says, “I have a situation with American 11, a possible hijack.” He adds that Flight 11 “departed Boston, going to LAX [Los Angeles International Airport]. Right now he’s south of Albany.” He says, “I’d like to scramble some fighters to go tail him.” Spence replies that he will contact Otis Air Base about the situation, and tells Bueno, “I’ll talk to these guys over here and see what we can do.” Bueno then adds that Flight 11 is currently airborne, is about 40 miles south of Albany, and is visible only on primary radar. [Federal Aviation Administration, 4/19/2002; 9/11 Commission, 9/30/2003 pdf file] Bueno also calls the air traffic control tower at Otis Air Base around this time, to alert it to Flight 11 and request military assistance (see (Between 8:30 a.m. and 8:40 a.m.) September 11, 2001). [Filson, 2003, pp. 47; Spencer, 2008, pp. 22] Whether he makes that call before or after he calls the Cape TRACON is unstated. Immediately after receiving the call from Bueno, Spence will call the Otis control tower to inform it of the situation, and he then calls the operations desk at Otis Air Base to let it know that it may be receiving orders (presumably from NEADS, NORAD’s Northeast Air Defense Sector) soon (see (8:36 a.m.-8:41) September 11, 2001). [9/11 Commission, 9/30/2003 pdf file]
Bueno Supposedly Violating Protocol - Bueno will say he decided to call the Cape TRACON based on his memory of a previous aircraft hijacking. [9/11 Commission, 9/22/2003 pdf file] But according to the 9/11 Commission Report, by trying to get military assistance through the TRACON, the “Boston Center did not follow the protocol in seeking military assistance through the prescribed chain of command.” [9/11 Commission, 7/24/2004, pp. 20] Indeed, Bueno will tell the 9/11 Commission that he knows his call should instead be to NEADS, “but due to the urgency of the circumstance [he] called directly to the FAA contact point for Otis.” [9/11 Commission, 9/22/2003 pdf file] And Spence will tell the Commission that arranging for fighters to be scrambled in response to a hijacking “is not the typical responsibility of an operations supervisor with the FAA,” like himself. He will also say that it is “unusual for the [air traffic control] centers to contact TRACON for information. Normally the FAA receives the call from the military for a scramble, but this time it went the other way around, and then the official order came back down from the military.” [9/11 Commission, 9/30/2003 pdf file]
Bueno Praised by Colleagues for Actions - However, according to the 9/11 Commission, “Bueno gets high marks” from the Boston Center personnel it interviews, “for instinctively calling FAA traffic approach personnel at the location where he knew the fighters to be—Otis [Air National Guard Base].” Even Colin Scoggins, the Boston Center’s military liaison, “who knew that the call had to go to NEADS, did not fault Bueno for trying to call the Air Force wing directly through other FAA personnel.” [9/11 Commission, 9/22/2003 pdf file]

Colin Scoggins, the military liaison at the FAA’s Boston Center, claims he makes his first call to NORAD’s Northeast Air Defense Sector (NEADS) regarding Flight 11. He later recalls that he informs NEADS that the aircraft is “20 [miles] south of Albany, heading south at a high rate of speed, 600 knots.” [Griffin, 2007, pp. 43] Flight 11 was over Albany at 8:26 (see (8:26 a.m.-8:29 a.m.) September 11, 2001). [Federal Aviation Administration, 9/17/2001 pdf file] At such a high speed, it would have reached 20 miles south of there around 8:28. However, Scoggins says he is quite certain he only arrives on the floor at Boston Center at around 8:35. He says that although he’d later tried to write up a chronology of events, he “couldn’t get a timeline that made any sense.” Furthermore, Scoggins claims that even before he’d arrived, Joseph Cooper, a Boston Center air traffic management specialist, had already phoned NEADS about the hijacking. [Griffin, 2007, pp. 43 and 335] The 9/11 Commission makes no mention of either call. It says “the first notification received by the military—at any level—that American 11 had been hijacked” is when Boston Center calls NEADS just before 8:38 a.m. (see (8:37 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] However, a report by ABC News is more consistent with Scoggins’ claims, indicating that Boston Center contacts NEADS about the hijacking earlier, at around 8:31. [ABC News, 9/11/2002] (Boston Center also contacts the FAA’s Cape Cod facility at 8:34 and requests that it notify the military about Flight 11 (see 8:34 a.m. September 11, 2001). Apparently around the same time, it tries contacting a military unit at Atlantic City (see (8:34 a.m.) September 11, 2001).) Scoggins says he makes “about 40 phone calls to NEADS” in total on this day. [Griffin, 2007, pp. 43] NEADS Commander Robert Marr later comments that Scoggins “deserves a lot of credit because he was about the only one that was feeding us information. I don’t know exactly where he got it. But he was feeding us information as much as he could.” [Michael Bronner, 2006]

After being informed of the hijacking of Flight 11, Tim Spence, an operational supervisor at the FAA’s Cape Terminal Radar Approach Control (TRACON), calls the air traffic control tower and then the operations desk at Otis Air National Guard Base, to let them know that they might soon be receiving an order to scramble the base’s fighter jets. [9/11 Commission, 9/30/2003 pdf file; 9/11 Commission, 2004] Daniel Bueno, a supervisor at the FAA’s Boston Center, has just called Spence at the Cape TRACON, which is located on Otis Air Base at Cape Cod, Massachusetts, and said he wanted fighter jets scrambled in response to Flight 11, which is a “possible hijack.” Spence told Bueno he would contact Otis Air Base and see what it could do to help (see 8:34 a.m. September 11, 2001). [Federal Aviation Administration, 4/19/2002; 9/11 Commission, 9/30/2003 pdf file; 9/11 Commission, 8/26/2004, pp. 12]
TRACON Supervisor Calls Otis Tower - Spence will later recall that in the five minutes following the call from Bueno, he makes “as many calls as possible.” He gets on the phone to the air traffic control tower at Otis Air Base, to notify the controllers there of the situation and receive information on who to call next, so as to facilitate Bueno’s request. Spence will recall that the Otis tower controller he speaks to gives him the telephone number for either Otis Air Base’s base operations or the supervisor of flying desk, which is the aviation section of the base operations desk. (He will be unable to recall exactly which number he is given.) Spence will say he “may have been given a second number” by the Otis tower controller, but he “does not recall directly.”
TRACON Supervisor Calls Operations Desk - Spence then calls Otis Air Base’s operations desk. He will later be unable to remember who he speaks with there. But, he will recall, the “general discussion” he has with them is “an introduction of his position, the relay of the information of a hijack from [the FAA’s Boston Center], and a request for information on how to get a fighter scramble.” During the call, Spence acknowledges that he has no authority to authorize a fighter scramble, but he advises those at the base to prepare to receive a scramble order (presumably from NEADS, NORAD’s Northeast Air Defense Sector), since such an order is “probably on its way.” The person at the operations desk gives Spence the phone number for NEADS.
Timing of Calls Unclear - The exact times when Spence calls the control tower and the operations desk at Otis Air Base are unclear. Spence will tell the 9/11 Commission that he makes the call to the control tower immediately after receiving the call from Bueno. [9/11 Commission, 9/30/2003 pdf file] That call ended just before 8:36 a.m. [Federal Aviation Administration, 4/19/2002] However, according to the 9/11 Commission Report, “the first notification received by the military—at any level—that American 11 had been hijacked” is when the FAA’s Boston Center calls NEADS just before 8:38 a.m. (see (8:37 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] If correct, that would indicate Spence calls the Otis tower at 8:38 a.m. or after. Bueno also called the Otis tower directly, to request military assistance in response to Flight 11 (see (Between 8:30 a.m. and 8:40 a.m.) September 11, 2001), and the tower controller subsequently contacts the base’s operations desk to alert it to the possible hijacking (see (Between 8:31 a.m. and 8:40 a.m.) September 11, 2001). [Filson, 2003, pp. 47; Spencer, 2008, pp. 22, 27-28] It is unclear whether the tower controller calls the operations desk before or after Spence calls it, although Spence will suggest to the 9/11 Commission that Otis Air Base “may have just received a call themselves regarding the situation” when he makes his calls, “but he is not sure.” [9/11 Commission, 9/30/2003 pdf file]

Gwilt/ Rome Sentinel]The FAA’s Boston Center calls NORAD’s Northeast Air Defense Sector (NEADS) in Rome, NY, to alert it to the suspected hijacking of Flight 11. According to the 9/11 Commission, this is “the first notification received by the military—at any level—that American 11 had been hijacked.” [9/11 Commission, 7/24/2004, pp. 20; 9/11 Commission, 8/26/2004, pp. 13] The call is made by Joseph Cooper, an air traffic controller at the Boston Center, and answered by Jeremy Powell, a technical sergeant on the NEADS operations floor. [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 25] Beginning the call, Cooper says: “Hi. Boston Center TMU [traffic management unit], we have a problem here. We have a hijacked aircraft headed towards New York, and we need you guys to, we need someone to scramble some F-16s or something up there, help us out.” Powell replies, “Is this real-world or exercise?” Cooper answers, “No, this is not an exercise, not a test.” [9/11 Commission, 7/24/2004, pp. 20] Shortly into the call, Powell passes the phone on to Lieutenant Colonel Dawne Deskins (see (8:38 a.m.) September 11, 2001). Deskins identifies herself to Cooper, and he tells her, “We have a hijacked aircraft and I need you to get some sort of fighters out here to help us out.” [Newhouse News Service, 1/25/2002; ABC News, 9/11/2002; Bamford, 2004, pp. 8; Spencer, 2008, pp. 26]
Military Claims Call Goes against Procedure - The 1st Air Force’s official history of the response to the 9/11 attacks will later suggest that Boston Center is not following normal procedures when it makes this call to NEADS. It states: “If normal procedures had taken place… Powell probably wouldn’t have taken that phone call. Normally, the FAA would have contacted officials at the Pentagon’s National Military Command Center who would have contacted the North American Aerospace Defense Command. The secretary of defense would have had to approve the use of military assets to assist in a hijacking, always considered a law enforcement issue.” The only explanation it gives for this departure from protocol is that “nothing was normal on Sept. 11, 2001, and many say the traditional chain of command went by the wayside to get the job done.” [Filson, 2003, pp. 51]
Accounts Conflict over Time of Call - There will be some conflict between different accounts, as to when this vital call from Boston Center to NEADS occurs. An ABC News documentary will indicate it is made as early as 8:31 a.m. [ABC News, 9/11/2002] Another ABC News report will state, “Shortly after 8:30 a.m., behind the scenes, word of a possible hijacking [reaches] various stations of NORAD.” [ABC News, 9/14/2002] NEADS logs indicate the call occurs at 8:40 a.m., and NORAD will report this as the time of the call in a press release on September 18, 2001. [Federal Aviation Administration, 9/17/2001 pdf file; North American Aerospace Defense Command, 9/18/2001] The 8:40 time will be widely reported in the media prior to the 9/11 Commission’s 2004 report. [Associated Press, 8/21/2002; BBC, 9/1/2002; Newsday, 9/10/2002; CNN, 9/11/2002] But tape recordings of the NEADS operations floor that are referred to in the 9/11 Commission Report place the call at 8:37 and 52 seconds. [9/11 Commission, 7/24/2004, pp. 20; Vanity Fair, 8/1/2006] If the 8:37 a.m. time is correct, this would mean that air traffic controllers have failed to successfully notify the military until approximately 12 minutes after they became certain that Flight 11 had been hijacked (see (8:25 a.m.) September 11, 2001), 16 minutes after Flight 11’s transponder signal was lost (see (Between 8:13 a.m. and 8:21 a.m.) September 11, 2001), and 24 minutes after the plane’s pilots made their last radio contact (see 8:13 a.m. September 11, 2001). [9/11 Commission, 6/17/2004] At 8:34, the Boston Center tried contacting the military through the FAA’s Cape Cod facility, which is located on Otis Air National Guard Base, but was told that it needed to call NEADS (see 8:34 a.m. September 11, 2001).

National Guard troops stationed at NORAD’s Northeast Air Defense Sector (NEADS) in Rome, New York.National Guard troops stationed at NORAD’s Northeast Air Defense Sector (NEADS) in Rome, New York. [Source: Rome Sentinel]At NORAD’s Northeast Air Defense Sector (NEADS), a huddle of people is gathered around one of the radar scopes. NEADS Commander Robert Marr initially thinks this hubbub is due to the NORAD training exercise (presumably Vigilant Guardian) that is taking place on this day (see (6:30 a.m.) September 11, 2001). He will later recall: “I’ve seen many exercises… and as I saw that huddle I said, ‘There’s got to be something wrong, something is happening here.’ You usually see that whenever they find a track on the scope that looks unusual; it’s usually an indicator that something is getting ready to kick off.” [Filson, 2003, pp. 55] According to author Lynn Spencer, Marr thinks the day’s exercise “is kicking off with a lively, unexpected twist.… His bet is that his simulations team has started off the exercise by throwing out a ‘heart attack card’ to see how the troops respond to a first-aid call from a fellow soldier, testing their first responder training.” [Spencer, 2008, pp. 26] He sends Lieutenant Colonel Dawne Deskins, the regional mission crew commander for the exercise, to check out what is going on. [Filson, 2003, pp. 55] Deskins speaks briefly over the phone with the FAA’s Boston Center about the Flight 11 hijacking (see (8:37 a.m.) September 11, 2001). [Spencer, 2008, pp. 26] She then runs back to the “battle cab”—the glass-walled room that overlooks the NEADS operations floor—and speaks to Marr with urgency in her voice. [Filson, 2003, pp. 55] She tells him: “It’s a hijacking, and this is real life, not part of the exercise. And it appears that the plane is heading toward New York City.” Although Deskins has specifically stated, “not part of the exercise,” Marr reportedly thinks, “This is an interesting start to the exercise.” According to Spencer, he thinks “This ‘real-world’ mixed in with today’s simex [simulated exercise] will keep [his staff members] on their toes.” Regardless of whether the crisis is real or not, Marr decides to instruct that the two alert F-15s at Otis Air National Guard Base be ordered to battle stations (see (8:40 a.m.) September 11, 2001).

One of the ID technicians at NORAD’s Northeast Air Defense Sector (NEADS) calls the FAA’s Boston Center, and learns that there have been “threats in the cockpit” of Flight 11. The communications team at NEADS is currently trying to quickly find out all they can about the hijacked plane, such as its flight number, tail number, and where it is. ID tech Shelley Watson calls the management desk at the Boston Center, which had alerted NEADS to the hijacking minutes earlier (see (8:37 a.m.) September 11, 2001), wanting to make sure she has all the information that is available on Flight 11. Her call is answered by Boston Center’s military liaison, Colin Scoggins. Scoggins tells Watson: “He’s being hijacked. The pilot’s having a hard time talking to the… I mean, we don’t know. We don’t know where he’s goin’. He’s heading towards Kennedy [International Airport in New York City]. He’s… 35 miles north of Kennedy now at 367 knots. We have no idea where he’s goin’ or what his intentions are.” Scoggins says, “I guess there’s been some threats in the cockpit,” and adds, “We’ll call you right back as soon as we know more info.” Master Sergeant Maureen Dooley is standing over Watson, relaying any pertinent information she hears to Major Kevin Nasypany. She calls to him, “Okay, he said threat to the cockpit!” [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 34]

Victor Saracini.Victor Saracini. [Source: Family photo]Just after Flight 175 enters the airspace of the FAA’s New York Center (see 8:40 a.m. September 11, 2001), its pilot reports to the air traffic controller now managing the flight a suspicious transmission he had heard on departing Boston’s Logan Airport. The pilot, Captain Victor Saracini, tells the controller, Dave Bottiglia: “We figured we’d wait to go to your center. Ah, we heard a suspicious transmission on our departure out of Boston, ah, with someone, ah, it sounded like someone keyed the mikes and said, ah, ‘Everyone, ah, stay in your seats.’” [New York Times, 10/16/2001; 9/11 Commission, 7/24/2004, pp. 21; Spencer, 2008, pp. 36] Saracini is presumably referring to one of the three radio transmissions from Flight 11, where the voice of a hijacker could be heard (see 8:24 a.m. September 11, 2001 and (8:34 a.m.) September 11, 2001). However, none of these had included the hijacker telling people to stay in their seats, as Saracini describes, although the second and third transmissions included the hijacker telling the passengers, “Nobody move.” [9/11 Commission, 7/24/2004, pp. 19] Bottiglia responds: “Oh, okay. I’ll pass that along.” Referring to the fact that this was the end of the transmission he heard, Saracini adds, “It cut out,” and then asks Bottiglia, “Did you copy that?” [Gregor, 12/21/2001 pdf file; Spencer, 2008, pp. 36-37] This is the last radio transmission from Flight 175. The 9/11 Commission will conclude that the plane is hijacked within the next four minutes (see (Between 8:42 a.m. and 8:46 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 20] According to author Lynn Spencer, since controllers are only given information on a need-to-know basis, Bottiglia was unaware there were problems with Flight 11, which has not yet entered his airspace. He touches his computer screen to connect to the hotline for his sector controller, and then reports: “UAL 175 just came on my frequency and he said he heard a suspicious transmission when they were leaving Boston. ‘Everybody stay in your seats’—that’s what he heard… just to let you know.” [New York Times, 10/16/2001; Spencer, 2008, pp. 36-37]

Major General Larry Arnold.Major General Larry Arnold. [Source: US Air Force]Major General Larry Arnold, the commander of the Continental United States NORAD Region (CONR), calls Colonel Robert Marr, the battle commander at NORAD’s Northeast Air Defense Sector (NEADS), who is seeking authorization to scramble fighter jets in response to the hijacked Flight 11, and instructs him to “go ahead and scramble them, and we’ll get authorities later.” [9/11 Commission, 7/24/2004, pp. 20; Spencer, 2008, pp. 38-39] After learning that the FAA wants NORAD assistance with a possible hijacking (see (8:38 a.m.) September 11, 2001), Marr tried calling Arnold at CONR headquarters, at Tyndall Air Force Base, Florida, for permission to scramble fighters from Otis Air National Guard Base in Massachusetts (see (8:38 a.m.) September 11, 2001). Arnold was in a teleconference (see (8:30 a.m.-8:40 a.m.) September 11, 2001), so Marr left a message requesting that Arnold call him back. [Aviation Week and Space Technology, 6/3/2002; Filson, 2003, pp. 55-56; Spencer, 2008, pp. 31] With the teleconference now over, Arnold calls Marr on a secure phone line and is informed of the ongoing situation. [9/11 Commission, 5/23/2003; 9/11 Commission, 2/3/2004 pdf file]
Marr Reports Hijacking, Wants to Scramble Fighters - Marr says the FAA’s Boston Center is “reporting a possible hijacked aircraft, real-world, somewhere north of JFK Airport.” He says, “I’ve got Otis [fighters] going battle stations [i.e. with the pilots in the cockpits but the engines turned off] and I’d like to scramble them to military airspace while we try to get approval for an intercept.” Arnold had wondered if the reported hijacking was a simulation, as part of a NORAD training exercise taking place on this day (see (8:40 a.m.) September 11, 2001), and therefore asks, “Confirm this is real-world?” Marr confirms that the hijacking is “real-world.”
Marr Lacks Details of Hijacked Flight - Arnold asks where the hijacked aircraft is and Marr replies: “We don’t have a good location. The FAA says they don’t have it on their scopes, but had it west of Boston and thought it was now heading to New York.” Arnold then asks, “Do we have any other information, type, tail, number of souls on board?” to which Marr replies, “I don’t have all the particulars yet, but we’ll pass them on as we get them.”
Arnold Tells Marr to Scramble Fighters - According to author Lynn Spencer, in response to Marr’s request to scramble the Otis fighters, “Arnold’s instincts tell him to act first and seek authorizations later.” [Spencer, 2008, pp. 38-39] He therefore says, “Go ahead and scramble them, and we’ll get authorities later.” [Filson, 2003, pp. 56; 9/11 Commission, 7/24/2004, pp. 20] Marr tells Arnold he will “scramble Otis to military airspace” while they try to figure out what is going on. [Grant, 2004, pp. 20] Arnold will later recall that it is his and Marr’s intention to place the fighters in “Whiskey 105”—military airspace over the Atlantic Ocean, just south of Long Island—“since neither he nor Marr knew where the hijacked aircraft was.” [9/11 Commission, 2/3/2004 pdf file] Arnold ends by saying, “Let me know when the jets get airborne,” and adds that he will “run this up the chain” of command. Marr will then direct the NEADS mission crew commander to issue the scramble order (see 8:45 a.m. September 11, 2001). Meanwhile, Arnold will call the NORAD operations center in Cheyenne Mountain, Colorado, about the hijacking, and officers there tell him they will contact the Pentagon to get the necessary clearances for the scramble (see (8.46 a.m.) September 11, 2001).

An emergency locator transmitter (ELT).An emergency locator transmitter (ELT). [Source: ELTA]A special radio transmitter that is carried by aircraft and designed to go off automatically if a plane crashes is activated in the New York area, more than two minutes before Flight 11 hits the World Trade Center. [New York Times, 10/16/2001; 9/11 Commission, 10/1/2003 pdf file; Aircraft Owners and Pilots Association, 1/22/2009]
Pilots Inform Controller of Emergency Signal - At 8:44 a.m. and 5 seconds, David Bottiglia, an air traffic controller at the FAA’s New York Center, receives information from one of the aircraft he is monitoring. The pilot of US Airways Flight 583 tells him: “I just picked up an ELT [emergency locator transmitter] on 121.5. It was brief, but it went off.” [New York Times, 10/16/2001; 9/11 Commission, 10/1/2003 pdf file] (121.5 megahertz is an emergency frequency that ELTs transmit their distress signals on. [Aircraft Electronics Association, 2009, pp. 36 pdf file; Aircraft Owners and Pilots Association, 1/22/2009] ) A minute later, at 8:45 a.m. and 8 seconds, Bottiglia hears the same thing from another of the aircraft he is monitoring. The pilot of Delta Airlines Flight 2433 tells him, “We picked up that ELT too, but it’s very faint.” [New York Times, 10/16/2001] However, Flight 11 has not yet crashed, and will hit the WTC over 90 seconds later, at 8:46 a.m. and 40 seconds (see 8:46 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 7]
ELTs Help Locate Crashed Aircraft - An emergency locator transmitter, or ELT, is a small electronic device, which is designed to automatically begin emitting a continuous and distinctive radio signal when subjected to crash-generated forces, so as to facilitate the locating of an aircraft if it crashes. ELTs are carried aboard most general aviation aircraft in the US and are usually located far back in the plane’s fuselage or in the tail surface, so that they will suffer only minimal damage in the event of a crash impact. [Federal Aviation Administration, 3/23/1990; US Department of the Army, 8/12/2008, pp. E-6 pdf file; Aircraft Electronics Association, 2009, pp. 36 pdf file; Aircraft Owners and Pilots Association, 1/22/2009]
Location Signal Comes from Unclear - The precise location from where the ELT signal is being transmitted is unclear. Around the time Flight 11 crashes, a participant in an FAA teleconference will say the signal was coming from the area Flight 11’s track was in before it disappeared from primary radar, about 20 miles from New York’s JFK International Airport. [Federal Aviation Administration, 9/11/2001] Peter McCloskey, a traffic management coordinator at the New York Center, will tell the 9/11 Commission that the ELT goes off “in the vicinity of Lower Manhattan.” [9/11 Commission, 10/1/2003 pdf file]
Many Signals Are False Alarms - ELT signals not determined to be false alarms are reported to the Air Force Rescue Coordination Center (AFRCC) at Langley Air Force Base in Virginia. [9/11 Commission, 10/1/2003 pdf file] Major Allan Knox, who works at the AFRCC, will tell the 9/11 Commission that he does not recall being informed of any ELT signals on September 11, but says the AFRCC will review its data to verify this statement. He will also say that at least 20 ELT signals go off each day, and that 97 percent of ELT signals are false alarms. [9/11 Commission, 10/6/2003 pdf file]
ELT Signal Is 'Clearly Indicative of a Crash' - However, Paul Thumser, an operations supervisor at the FAA’s New York Center with 20 years’ experience as an air traffic controller, and who is also an experienced airline pilot, will tell the 9/11 Commission that the ELT in a Boeing 767 cannot be triggered by the pilot. (The two aircraft that hit the WTC are 767s.) He will also say that the sensitivity setting for the ELT in a 767 is not low, and so it should be impossible for a hard turn or a hard landing to accidentally cause the ELT to go off. Thumser will say that “he judged it would have to be a serious impact to set the ELT off.” [9/11 Commission, 10/1/2003 pdf file] Terry Biggio, the operations manager at the FAA’s Boston Center, will similarly tell the 9/11 Commission that an ELT signal “is clearly indicative of a crash.” [9/11 Commission, 9/22/2003]
FAA Manager Believes Signal Unrelated to Flight 11 Crash - Noting that the ELT goes off prior to Flight 11 hitting the WTC, Mike McCormick, the manager of the FAA’s New York Center, will tell the 9/11 Commission that his “best hypothesis” is that the activation of an ELT at this time is “unrelated to the event” of Flight 11 crashing. [9/11 Commission, 12/15/2003 pdf file] However, there are no reports of an ELT going off at the time when Flight 11 hits the WTC. Furthermore, another ELT will be activated in the New York area around five minutes before the second plane hits the WTC (see 8:58 a.m. September 11, 2001). [Federal Aviation Administration, 9/11/2001, pp. 37 pdf file] Despite the pilots’ reports of picking up an ELT signal just before Flight 11 crashes, the AFRCC will inform the 9/11 Commission that a “historical ELT data search” found “no ELT signal being heard by the satellites” for the area within a radius of 50 nautical miles (about 57.5 miles) of JFK International Airport between 8:00 a.m. and 10:30 a.m. on this day.

On the operations floor at NORAD’s Northeast Air Defense Sector (NEADS), Major Kevin Nasypany, the facility’s mission crew commander, instructs Major James Fox, the leader of the weapons team, to launch fighter jets from Otis Air National Guard Base in Cape Cod, Massachusetts. [Vanity Fair, 8/1/2006] Nasypany has just received this order—to launch the jets—from Colonel Robert Marr, the NEADS battle commander. [9/11 Commission, 8/26/2004, pp. 15 and 88] Marr issued it after seeking permission to do so from Major General Larry Arnold, the commanding general of NORAD’s Continental Region (CONR) (see (8:42 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] Marr will later claim, “My intent was to scramble Otis to military airspace while we found out what was going on.” [Filson, 2003, pp. 56] Nasypany gives Fox a coordinate for just north of New York City, and tells him, “Head ‘em in that direction.” [Vanity Fair, 8/1/2006] The jets will be scrambled from Otis a minute later (see 8:46 a.m. September 11, 2001), but there will be conflicting accounts of what their initial destination is (see (8:53 a.m.-9:05 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] Interestingly, the 9/11 Commission will later state that, “Because of a technical issue, there are no NEADS recordings available of the NEADS senior weapons director and weapons director technician position responsible for controlling the Otis scramble.” [9/11 Commission, 7/24/2004, pp. 459]

Two F-15 fighter jets are scrambled from Otis Air National Guard Base in Cape Cod, Massachusetts, which is 153 miles from New York City. The fighters are launched in response to the hijacked Flight 11, but this plane is already crashing into the World Trade Center at this time (see 8:46 a.m. September 11, 2001). [Washington Post, 9/15/2001; CNN, 9/17/2001; North American Aerospace Defense Command, 9/18/2001; 9/11 Commission, 6/17/2004]
Delay - The FAA’s Boston Center alerted NORAD’s Northeast Air Defense Sector (NEADS) to the hijacking of Flight 11 and requested that fighter jets be scrambled at just before 8:38 a.m. (see (8:37 a.m.) September 11, 2001), but the mission crew commander at NEADS only instructed the leader of his weapons team to launch the Otis fighters at 8:45 a.m. (see 8:45 a.m. September 11, 2001). [Vanity Fair, 8/1/2006]
Otis Aircraft Head to Runway - As soon as the pilots at Otis Air Base are strapped into their aircraft, the green light directing them to launch goes on. They start their engines and taxi out of the hangar to the nearest runway. One of the pilots, Lt. Col. Timothy Duffy, radios his command post for guidance, asking, “Do you have words?” The response he gets is, “Possible hijack, American Flight 11, 737, flight level 290 [29,000 feet], over JFK [International Airport in New York City].” (This flight information is partly incorrect, since American 11 is a 767, not a 737.) According to the Cape Cod Times, the jets will be up in the air before their radar kicks in. [Cape Cod Times, 8/21/2002; Spencer, 2008, pp. 42] The Otis pilots have already been preparing for the scramble order to come since learning of the hijacking from the FAA’s Cape Cod facility, some time shortly after 8:34 a.m. (see (8:36 a.m.-8:41) September 11, 2001). [BBC, 9/1/2002; Spencer, 2008, pp. 27-30] Their jets are reportedly not airborne until seven minutes after being scrambled, at 8:53 a.m. (see 8:53 a.m. September 11, 2001) and there will be conflicting accounts of what their original destination is (see (8:53 a.m.-9:05 a.m.) September 11, 2001).

Judy Martz.Judy Martz. [Source: Publicity photo]Emergency managers from around the US, including Federal Emergency Management Agency (FEMA) Director Joseph Allbaugh and representatives from the emergency management agencies of 47 states, are away from their home states at the time of the terrorist attacks, attending the annual conference of the National Emergency Management Association (NEMA) at a resort in Big Sky, Montana. The main focuses of the event have included the issues of domestic terrorism and weapons of mass destruction. [New York Times, 9/12/2001; State Government News, 10/2001 pdf file] The conference began on September 8, and was originally planned to continue until September 12 (see September 8-11, 2001). [Natural Hazards Observer, 3/2001; National Emergency Management Association, 8/15/2001]
Emergency Managers Learn of Attacks - At 9:00 a.m., conference attendees are scheduled to participate in a series of sessions on domestic preparedness, which has been a key topic for NEMA over the past three years. [National Emergency Management Association, 8/15/2001; State Government News, 10/2001 pdf file] According to the New York Times, “One of the day’s main seminar topics was how to prepare for terrorist attacks.” [New York Times, 9/12/2001] However, numerous pagers go off as officials are notified of the events in New York. By the time officials gather around the television in the resort’s bar to see what is happening, the second plane has hit the World Trade Center (see 9:03 a.m. September 11, 2001) and the nature of the emergency is obvious. [Stateline (.org), 9/10/2002]
Emergency Managers Respond to Attacks - After the emergency managers at the conference see the coverage of the attacks on television, they “automatically organized themselves into particular groups to focus on transportation issues or to capture information,” Trina Hembree, the executive director of NEMA, will later recall. [Stateline (.org), 10/11/2001] The emergency managers, along with federal personnel and private-sector members, go about coordinating their jurisdictions’ responses to the attacks from the resort. Hotel employees add phone lines and equipment so as to enable communication and the tracking of events. A 24-hour emergency operations center is set up, and teams are organized to address specific areas, such as transportation and medical needs. The emergency managers monitor events and stay in contact with their agencies by phone, and also attend briefings at the resort, where they are updated on the national situation. [State Government News, 10/2001 pdf file]
State of Emergency Declared in Montana - Partly due to concerns over the safety of the emergency management officials at the conference, Montana Governor Judy Martz declares a state of emergency. [Stateline (.org), 9/13/2001] Furthermore, roads to the Big Sky resort are closed, and security for the resort is provided by the local sheriff’s department and volunteer fire department, the Montana Highway Patrol, the Montana National Guard, and the FBI.
Arrangements Made to Fly Key Officials Home - The conference’s organizers arrange for military aircraft to fly state emergency management leaders back to their capitals. [New York Times, 9/12/2001; State Government News, 10/2001 pdf file] Allbaugh and officials from several states that are directly involved in the attacks are flown home throughout the day (see (After 11:00 a.m.) September 11, 2001, (After 11:00 a.m.) September 11, 2001, and (After 4:30 p.m.) September 11, 2001), but others at the conference have to drive long distances back to their states.
Emergency Managers 'Not Where They Wanted to Be' - As one news report will later describe, when the attacks occur, “emergency managers were not where they wanted to be.” FEMA spokesman Mark Wolfson will note the inconvenient timing of the attacks, saying that FEMA officials do not know whether they were timed to catch emergency officials off guard. “That would be speculation,” he says. “But it is something that law enforcement investigators might be looking at.” [Stateline (.org), 9/13/2001; State Government News, 10/2001 pdf file] NEMA is the professional association of state emergency management directors. [Natural Hazards Observer, 3/2001] Hundreds of state emergency management officials, including almost all of the US’s state emergency management directors, and most of the senior FEMA staff are in Montana for its annual conference.

In the National Military Command Center (NMCC) at the Pentagon, personnel apparently become aware of the first attack on the World Trade Center from watching the reports on television. According to Steve Hahn, an operations officer there, “We monitor the television networks in the center, and along with the rest of America we saw the smoke pouring from the tower.” Dan Mangino, who is also an operations officer at the NMCC, says, “At first, we thought it was a terrible accident.” [American Forces Press Service, 9/7/2006] The 9/11 Commission later says, “Most federal agencies learned about the crash in New York from CNN.” [9/11 Commission, 7/24/2004, pp. 35] Whether the NMCC was already aware that a hijacking was underway is unclear. According to military instructions, the NMCC is “the focal point within Department of Defense for providing assistance” in response to hijackings in US airspace, and is supposed to be “notified by the most expeditious means by the FAA.” [US Department of Defense, 6/1/2001 pdf file] Boston Air Traffic Control Center started notifying the chain of command of the suspected hijacking of Flight 11 more than 20 minutes earlier (see 8:25 a.m. September 11, 2001). And at 8:32, the FAA’s Command Center in Herndon informed FAA headquarters of the possible hijacking (see 8:28 a.m. September 11, 2001). Yet, according to the 9/11 Commission, although the “FAA headquarters began to follow the hijack protocol,” it “did not contact the NMCC to request a fighter escort.” Supposedly, the first that the military learned of the hijacking was when Boston Air Traffic Control Center contacted NORAD’s Northeast Air Defense Sector (NEADS) about it, at around 8:37 a.m. (see (8:37 a.m.) September 11, 2001). The earliest time mentioned by the 9/11 Commission that the NMCC learns of the Flight 11 hijacking is 9 a.m. (see 9:00 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 19-20 and 35]

[9/11 Commission, 10/30/2003 pdf file] NEADS was alerted to the hijacking of Flight 11 at 8:37 a.m. (see (8:37 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] Stuart now calls the Air Force desk at the NMJIC about it.

[Washington Times, 9/25/1997; Joint Chiefs of Staff, 2/6/2006] It “forms the heart of timely intelligence support to national-level contingency operations,” according to James Clapper, a former director of the Defense Intelligence Agency. And during a crisis, it “serves as a clearinghouse for all requests for national-level intelligence information.” [Joint Forces Quarterly, 3/1994 pdf file] However, Stuart will later recall that the NMJIC can provide him with “no additional relevant information” on the hijacking. Stuart then calls Robert Del Toro, an intelligence officer with the 1st Air Force at Tyndall Air Force Base, Florida. But, Stuart will say, the 1st Air Force also has “no further information” about the hijacking. [9/11 Commission, 10/30/2003 pdf file]

Technicians on the operations floor at NORAD’s Northeast Air Defense Sector (NEADS) receive what is apparently their first notification that a plane has hit the World Trade Center, in a phone call from the FAA’s Boston Center. [Vanity Fair, 8/1/2006] NEADS ID technicians are currently trying to locate Flight 11, when they are called by Colin Scoggins, the military liaison at the Boston Center. ID tech Stacia Rountree answers the call. In response to Scoggins’s information, Rountree says to her colleagues, “A plane just hit the World Trade Center.” She asks Scoggins, “Was it American 11?” He tells her this is not confirmed. [Spencer, 2008, pp. 50] Another of the ID techs, Shelley Watson, starts murmuring in response to the news: “Oh my God. Oh God.

An article in the New York Times will later suggest that officials in the Pentagon’s National Military Command Center (NMCC) promptly become aware of the problems with Flight 77, long before NORAD’s Northeast Air Defense Sector (NEADS) is alerted to the flight. The article will state, “During the hour or so that American Airlines Flight 77 [is] under the control of hijackers, up to the moment it struck the west side of the Pentagon, military officials in [the NMCC are] urgently talking to law enforcement and air traffic control officials about what to do.” [New York Times, 9/15/2001] This appears consistent with what would be expected under normal procedures. According to the FAA’s acting Deputy Administrator Monte Belger: “Prior to 9/11, FAA’s traditional communication channel with the military during a crisis had been through the National Military Command Center (NMCC). They were always included in the communication net that was used to manage a hijack incident.” He will say that, since the FAA does not have direct dedicated communication links with NORAD, in a hijack scenario the NMCC has “the responsibility to coordinate [the Defense Department]‘s response to requests from the FAA or the FBI.” [9/11 Commission, 6/17/2004 pdf file; 9/11 Commission, 6/17/2004] NEADS reportedly is not alerted to Flight 77 until significantly later: at 9:24 a.m. by some accounts (see (9:24 a.m.) September 11, 2001), or, according to other accounts, at 9:34 a.m., when it only learns that Flight 77 is missing (see 9:34 a.m. September 11, 2001).

A typical F-15.A typical F-15. [Source: US Air Force]Radar data will show that the two F-15s scrambled from Otis Air National Guard Base in Cape Cod, Massachusetts, are airborne by this time. [Washington Post, 9/15/2001; North American Aerospace Defense Command, 9/18/2001; 9/11 Commission, 7/24/2004, pp. 20] It is now eight minutes since the mission crew commander at NORAD’s Northeast Air Defense Sector (NEADS) ordered that the jets be launched (see 8:45 a.m. September 11, 2001). [Vanity Fair, 8/1/2006] It is 40 minutes since air traffic controllers had their last communication with Flight 11 (see 8:13 a.m. September 11, 2001), and 28 minutes since they became certain that the aircraft was hijacked (see (8:25 a.m.) September 11, 2001). Flight 11 crashed into the World Trade Center seven minutes ago (see 8:46 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 7, 19 and 459]
Commander Wants Fighters Sent to New York - In Rome, New York, NEADS has just received news of the plane hitting the WTC (see 8:51 a.m. September 11, 2001). Major Kevin Nasypany, the facility’s mission crew commander, is asked what to do with the Otis fighters. He responds: “Send ‘em to New York City still. Continue! Go! This is what I got. Possible news that a 737 just hit the World Trade Center. This is a real-world.… Continue taking the fighters down to the New York City area, JFK [International Airport] area, if you can. Make sure that the FAA clears it—your route all the way through.… Let’s press with this.” [Vanity Fair, 8/1/2006] Yet there will be conflicting reports of the fighters’ destination (see (8:53 a.m.-9:05 a.m.) September 11, 2001), with some accounts saying they are directed toward military-controlled airspace off the Long Island coast.

An air traffic controller at the FAA’s Boston Center directs the two fighter jets that took off from Otis Air National Guard Base in response to the hijacked Flight 11 toward a new heading, based on instructions he has just received from NORAD’s Northeast Air Defense Sector (NEADS).
NEADS Gave New Heading for Fighters - The Boston Center controller, who is working at the Cape Sector radar position, has just been contacted by someone from NEADS. The caller from NEADS, referring to the two fighters from Otis Air Base, said, “The heading that we gave him on, I guess, is a bad heading.” [Federal Aviation Administration, 9/11/2001; 9/11 Commission, 2004] (The original flight strip for the fighters gave a destination of New York’s JFK International Airport. [9/11 Commission, 9/22/2003 pdf file] ) The caller said the fighters’ target was “now south of JFK,” and added, “Can you direct the Panta flight [i.e. the two Otis fighters] towards that now?” The controller replied: “If I’m talking to him, I don’t know where that target [is]. I don’t even see the target at all.” [Federal Aviation Administration, 9/11/2001] The “target,” Flight 11, crashed into the World Trade Center at 8:46 a.m. (see 8:46 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 7] However, the caller explained that NEADS had just talked to Colin Scoggins, the military liaison at the Boston Center, and Scoggins said the target was “south of JFK now.” The caller therefore reiterated, “We want to get [the Otis fighters] headed in that direction.” The controller confirmed, “I’ll do that.”
Controller Passes on New Heading to Pilot - Seconds later, Lieutenant Colonel Timothy Duffy, one of the pilots of the two fighters out of Otis Air Base, checks in with the Boston Center controller. Duffy says, “Boston Center, Panta 45 with you out of 13-5 for 290.” [Federal Aviation Administration, 9/11/2001; 9/11 Commission, 2004] (“Panta 45” is Duffy’s call sign. [Spencer, 2008, pp. 113] ) The controller tells Duffy, “Panta 45, roger, fly heading of 260.” Duffy confirms the new heading. The controller then instructs, “Maintain block 290.” Duffy confirms, “Six zero on the heading, climbing to flight level [of] 290.” The controller will then tell Duffy that Flight 11 has crashed into the WTC (see 8:55 a.m. September 11, 2001).

One of the two fighter pilots who took off in response to the hijacked Flight 11 is told by air traffic control that Flight 11 has crashed into the World Trade Center, and yet both pilots will later claim they are unaware of this crash until after 9:03 a.m., when Flight 175 hits the WTC. [Federal Aviation Administration, 9/11/2001; Cape Cod Times, 8/21/2002; ABC News, 9/11/2002; Filson, 10/2/2002; Filson, 10/22/2002; 9/11 Commission, 2004] Lieutenant Colonel Timothy Duffy and Major Daniel Nash took off in their F-15s from Otis Air National Guard Base in Cape Cod, Massachusetts, at 8:46 a.m. (see 8:46 a.m. September 11, 2001), but were unaware that at the same time, Flight 11 was crashing into the WTC (see 8:46 a.m. September 11, 2001). [Filson, 2003, pp. 57; 9/11 Commission, 7/24/2004, pp. 20]
Controller Tells Pilot that Flight 11 Crashed into WTC - Duffy has just checked in with the air traffic controller at the FAA’s Boston Center who is working at the Cape Sector radar position, and the controller has given him a new heading to fly toward (see 8:54 a.m.-8:55 a.m. September 11, 2001). The controller now asks Duffy, “I understand you’re going out to look for American 11, is that correct?” Duffy replies, “Affirmative.” The controller then tells Duffy that Flight 11 has crashed. He says, “Okay, I just got information that the aircraft has been, uh, crashed into the World Trade Center, so I’m not quite sure what your intentions are, if you’re still going to head that way or you may want to talk to your operations.” Duffy responds, “Okay, we’re going to go over and talk to Huntress right now.” (“Huntress” is the call sign for NORAD’s Northeast Air Defense Sector, NEADS.) [Federal Aviation Administration, 9/11/2001; 9/11 Commission, 2004] Although Duffy contacts NEADS (see (8:56 a.m.-8:57 a.m.) September 11, 2001), it is unclear whether he talks about the crash, as he indicates he is going to, since, according to the 9/11 Commission Report, “there are no NEADS recordings available of the NEADS senior weapons director and weapons director technician position responsible for controlling the Otis [Air National Guard Base] scramble” (see (8:30 a.m.-3:00 p.m.) September 11, 2001). [9/11 Commission, 1/7/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 459] It is also unclear whether Duffy passes on the information about Flight 11 hitting the WTC to Nash. But in later interviews, both pilots will claim they were unaware of Flight 11 hitting the WTC until they were informed that a second aircraft had hit the WTC, shortly after that second crash occurred (see (9:03 a.m.) September 11, 2001 and 9:06 a.m.-9:07 a.m. September 11, 2001). [9/11 Commission, 2004; Spencer, 2008, pp. 84]
Pilots Deny Learning of First Crash - The Cape Cod Times will report that Nash “doesn’t even recall hearing that the first plane hit.” [Cape Cod Times, 8/21/2002] Nash will tell author Leslie Filson that when he and Duffy are informed of the second plane hitting the WTC, they are “still under [the] impression [that] American 11 was still airborne” and are “shocked, because we didn’t know the first one had even hit.” [Filson, 10/2/2002] And Nash will tell the 9/11 Commission that he “does not remember at which point during the morning of 9/11 he heard of the first crash at the WTC.” He will say he does “remember that the FAA controller he communicated with during flight told him of the second crash,” but add that “this was strange to hear at the time, since he had not been told of the first.” [9/11 Commission, 10/14/2003 pdf file] Duffy will tell ABC News that when he is informed of the second crash, “I thought we were still chasing American 11.” [ABC News, 9/11/2002] He will tell Filson that when he learns of this second crash, “I didn’t know [the] first one hit” the WTC. [Filson, 10/22/2002] And he will tell the 9/11 Commission that when he “received word that a second aircraft had hit the WTC,” he “still thought they were responding to a hijacked American [Airlines] airliner.” [9/11 Commission, 1/7/2004 pdf file]

Paul Worcester.Paul Worcester. [Source: Paul Blackmore / Cape Cod Times]Senior commanders at Otis Air National Guard Base in Cape Cod, Massachusetts, become aware of the attacks on the World Trade Center from television coverage, and one commander then orders the base’s battle staff to assemble. The commanders have just been in the first of the base’s regular Tuesday morning meetings, which ended at 8:55 a.m. They are taking a short break before the next meeting, which is scheduled for 9:00 a.m., and are apparently unaware that a plane has crashed into the WTC.
Wing Commander Sees Burning WTC on Television - One of those in the meeting was Lieutenant Colonel Paul Worcester, the logistics group commander of the 102nd Fighter Wing, which is based at Otis. As Worcester walks past the break room he notices that everyone inside it is fixated on the television. He goes in to find what they are watching and gets his first sight of the coverage of the burning North Tower. Worcester finds it odd that a plane could have hit the WTC, and thinks to himself: “On such a clear day, planes don’t just go astray. That just doesn’t happen.” Although he is aware that the base’s two F-15s that are kept on alert have been scrambled in response to a suspected hijacking (see 8:46 a.m. September 11, 2001), he does not connect this with what he is seeing on television.
Commanders See Second Attack - Worcester is joined in the break room by more of the senior commanders. They watch as the live television coverage shows Flight 175 crashing into the South Tower (see 9:03 a.m. September 11, 2001), and all of them then realize that America is under attack. One commander immediately shouts out, “We need to go to battle staff!” The senior commanders disperse and head toward the adjacent operations building, where they will reconvene in the battle cab of the installation operations center (see Shortly After 9:03 a.m. September 11, 2001). A voice sounds out over the base’s loudspeakers: “The commander has ordered the 102nd core battle staff to assemble. Please report to the operations building immediately.”
Unit Mobilizes for War - Subsequently, as author Lynn Spencer will describe: “Under the leadership of the [102nd Fighter] Wing commander, the various subordinate group commanders cross-brief on scramble activity, training flight issues, available munitions, personnel available to begin uploading more fighters to combat-ready status, security force increases, and more. In short, they begin to mobilize the wing for war, keeping NEADS [NORAD’s Northeast Air Defense Sector] in the loop on their preparations.” [Spencer, 2008, pp. 87-88, 153-154]
Base Learned of First Hijacking 20 Minutes Earlier - The 102nd Fighter Wing of the Massachusetts Air National Guard, which is based at Otis Air Base, is responsible for protecting the Northeast United States, including New York, Washington, and Boston. Its mission includes defending the region against terrorist attacks. [Cape Cod Times, 9/12/2001; Cape Cod Times, 9/12/2001] On a typical day, it has about a dozen pilots on duty. [Cape Cod Times, 9/15/2001] It is equipped with 18 F-15 fighter jets, two of which are kept on 24-hour alert, ready to be in the air within five minutes of being called upon. [Boston Globe, 9/15/2001; Cape Cod Times, 9/21/2001] These were the two jets that launched at 8:46 a.m. in response to the hijacking of Flight 11. [9/11 Commission, 7/24/2004, pp. 20] The base was notified about this first hijacking shortly after 8:34 a.m. (see (8:36 a.m.-8:41) September 11, 2001). [Spencer, 2008, pp. 27-28] Why the senior commanders did not initiate their crisis response at that time is unclear.

Fire department commanders in the lobby of the North Tower of the World Trade Center instruct an officer with the Port Authority Police Department and building personnel in the North Tower to evacuate the South Tower of the WTC. They do this not because of concern about a plane hitting the South Tower, but because, in their judgment, “the impact of the plane into the North Tower made the entire complex unsafe,” according to the 9/11 Commission Report. The exact time at which the fire chiefs give the instruction is unclear; the 9/11 Commission Report will only state that they have given it “by approximately 8:57.” However, according to the 9/11 Commission, “there is no evidence that this advice was communicated effectively to the building personnel in the South Tower.” [9/11 Commission, 4/19/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 287, 290] All the same, at 9:02 a.m., an announcement will be made over the public address system in the South Tower, telling workers that they can begin an orderly evacuation of the building if conditions warrant it (see 9:02 a.m. September 11, 2001).

A special radio transmitter that is carried by aircraft and designed to go off automatically if a plane crashes is activated in the New York area, several minutes before Flight 175 hits the World Trade Center. David Bottiglia, an air traffic controller at the FAA’s New York Center, receives information from one of the aircraft he is monitoring. A few seconds before 8:59 a.m., the pilot of US Airways Flight 583 tells him, “I hate to keep burdening you with this stuff, but now we’re picking up another ELT on 21.5.” [Federal Aviation Administration, 9/11/2001, pp. 37 pdf file; 9/11 Commission, 10/1/2003 pdf file; 9/11 Commission, 2004] An “ELT” is an emergency locator transmitter, a device carried on most general aviation aircraft in the US that is designed to automatically begin transmitting a distress signal if a plane should crash, so as to help search and rescue attempts at locating the downed aircraft. [Federal Aviation Administration, 3/23/1990; US Department of the Army, 8/12/2008, pp. E-6 pdf file; Aircraft Owners and Pilots Association, 1/22/2009] “21.5” refers to the emergency frequency of 121.5 megahertz that ELTs transmit their distress signals on. [Aircraft Electronics Association, 2009, pp. 36 pdf file] While the pilot’s information would mean an ELT is activated at around 8:58 a.m., Flight 175 will crash into the WTC several minutes later, at 9:03 a.m. and 11 seconds (see 9:03 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 8] And yet there are no reports of an ELT going off at the time of the crash itself. The pilot of Flight 583 earlier on informed Bottiglia of another ELT signal, which had been transmitted shortly before Flight 11 hit the WTC (see 8:44 a.m. September 11, 2001).

Mike Morell, President Bush’s CIA briefer, calls the CIA’s operations center to see if anyone there knows more about what has happened at the World Trade Center and is told that the WTC was hit by a large commercial airliner. [Studies in Intelligence, 9/2006 pdf file; Morell and Harlow, 2015, pp. 48] Morell learned that a plane had crashed into the WTC as he was being driven to the Emma E. Booker Elementary School in Sarasota, Florida, where Bush is going to attend a reading event. White House press secretary Ari Fleischer, who was in the same vehicle as him, received a pager message stating what had happened and then exclaimed, “A plane just hit the World Trade Center” (see (Between 8:48 a.m. and 8:55 a.m.) September 11, 2001). [Bamford, 2004, pp. 17; Politico Magazine, 9/9/2016] Fleischer asked Morell if he knew anything about the incident. “As the in-house intelligence officer, Morell was the man they looked to for the scoop when something startling happened,” journalist and author Mark Bowden will comment. [Bowden, 2012, pp. 3] The CIA officer knew nothing about the incident but said he would make some calls to inquire about it.
CIA Officer Thought the Crash Was an Accident - Morell initially assumed the crash was an accident. “The image in my mind,” he will later recall, “was of a small plane losing its way in a storm or fog and hitting the World Trade Center. I figured the death toll would include only two or three people on the plane and perhaps a few more in offices at the point of impact.” All the same, after entering the school, he calls the operations center at CIA headquarters in Langley, Virginia, to see if anyone there knows more about the crash. He assumes someone there likely will because, he will write, “I had come to rely on the group of hard-working officers in the center, both to set aside for me key pieces of overnight reporting and to answer my many questions.”
CIA Officer Is Told a Large Plane Hit the WTC - However, the duty officer Morell talks to is able to tell him little more than what he already knows. The one new detail the duty officer provides, Morell will recall, is that “the initial reports indicated that the plane [that hit the WTC] was a large commercial jet.” “My hope that this was not terrorism started to fade,” he will write. Morell then walks into the holding room next to the classroom where Bush is going to listen to some children reading and notices that the time is 9:00 a.m. Minutes later, he will learn about Flight 175 crashing into the WTC (see 9:03 a.m. September 11, 2001) and realize immediately that the incident is a “deliberate act of terrorism.” [Studies in Intelligence, 9/2006 pdf file; Morell and Harlow, 2015, pp. 47-48]

Martin Richard.Martin Richard. [Source: Kevin Mingora]Several F-15 fighter jets from Otis Air National Guard Base in Massachusetts fly out over the Atlantic Ocean for a scheduled training mission, but the pilots are unaware of the hijackings taking place and the plane crashes at the World Trade Center. The fighters belong to the 102nd Fighter Wing. [102nd Fighter Wing, 2001; Airman, 9/3/2011] Their mission is an “ordinary training session,” according to the Cape Cod Times. [Cape Cod Times, 9/11/2006] Major Martin Richard, one of the pilots involved, will describe it as a “normal training mission.” [Richard, 2010, pp. 9] It is being carried out in “Whiskey 105,” an area of military training airspace over the Atlantic Ocean, southeast of Long Island. [102nd Fighter Wing, 2001; Airman, 9/3/2011] According to most accounts, six of the 102nd Fighter Wing’s F-15s are taking part. [102nd Fighter Wing, 2001; North American Aerospace Defense Command, 9/11/2001; Cape Cod Times, 9/11/2006; Spencer, 2008, pp. 155] But Richard will write in a 2010 book that eight of the unit’s F-15s are involved.
Training Mission Is a 'Mock War Scenario' - The “defensive counter-air” mission, according to Richard, is intended to have the fighters splitting into two teams: the “blue air”—the “good guys”—versus the “red air,” their adversaries. In a defensive counter-air mission, Richard will write, “the goal is [to] protect a point on the ground. Our training objective focused on ensuring flawless radar operations to be able to build an accurate picture of the threat’s formation, target the threat in the most effective manner, and ensure, through mutual support, that all blue air forces returned unscathed.” The “mock war scenario” that is played out is “an exciting sortie to do as a practice mission, and it took a great deal of organization to make happen,” according to Richard. [Richard, 2010, pp. 10] A KC-135 tanker plane from the 101st Air Refueling Wing in Bangor, Maine, is scheduled to refuel the fighters during the mission. [102nd Fighter Wing, 2001; Spencer, 2008, pp. 153; Bangor Daily News, 9/9/2011]
Pilot Hears Unusual Radio Communications - The fighters take off from Otis Air Base at 9:00 a.m. [9/11 Commission, 10/14/2003 pdf file] They then fly out toward the Whiskey 105 training airspace. [102nd Fighter Wing, 2001; Airman, 9/3/2011] Richard will recall that at this time, “[e]verything was exceedingly normal until we heard some unfamiliar radio communication between [the FAA’s] Boston Center and some civilian airliners.” He will say that this “got my attention, but more because it was out of the norm, not because it was especially noteworthy.”
Fighters Fly to Opposite Sides of Airspace - Richard commands the other fighter pilots to complete their pre-mission safety checks and then readies them “for the simulated war we had planned hours before.” After entering Whiskey 105, the fighters carry out a warm-up maneuver. Richard then sends the fighters simulating the “red air” to the west side of the training airspace, while the other fighters—the “blue air”—take up their position about 80 miles away, on the east side of the airspace. [Richard, 2010, pp. 12-13] But then, shortly after they arrive in Whiskey 105, at around 9:25 a.m., the pilots will learn of the first crash at the WTC and be recalled to their base (see (9:25 a.m.-9:45 a.m.) September 11, 2001). Some of the fighters subsequently take off again to help protect US airspace, but that will be after the terrorist attacks have ended (see (10:30 a.m.) September 11, 2001 and (Shortly After 10:30 a.m.) September 11, 2001). [102nd Fighter Wing, 2001; 9/11 Commission, 10/14/2003 pdf file; Cape Cod Times, 9/11/2006; Spencer, 2008, pp. 244-246; Richard, 2010, pp. 13]
Fighters on Training Are Unarmed - The fighters involved in the training mission have no ordnance on them. [102nd Fighter Wing, 2001] According to Technical Sergeant Michael Kelly, the full-time technician in the command post at Otis Air Base, they are “in an exercise configuration” and therefore “at a ‘safe guns’ (non-firing) weapons posture.” Furthermore, the fighters “more than likely had only one fuel tank.” (F-15s can carry three fuel tanks.) If these fighters were to be used for “long air superiority/sovereignty missions,” Kelly will say, they would need “‘hot’ (live) guns, missiles, and extra gas tanks.” [9/11 Commission, 10/14/2003 pdf file]
Fighters Scrambled after Flight 11 Also Fly in Training Airspace - The pilots on the training mission saw the two of their unit’s F-15s that are kept on “alert”—ready for immediate launch—taking off from Otis Air Base in response to the hijacked Flight 11 (see 8:46 a.m. September 11, 2001), but were unaware of the reason for the scramble (see (8:30 a.m.-8:59 a.m.) September 11, 2001). [102nd Fighter Wing, 2001; Cape Cod Times, 9/11/2006] (One of the pilots of those F-15s, Daniel Nash, is reportedly standing in for the usual “alert” pilot, who is “scheduled for training” on this day, presumably taking part in the training mission in Whiskey 105. [Cape Cod Times, 8/21/2002] ) The two F-15s launched in response to Flight 11 were actually directed toward Whiskey 105 after taking off (see (8:53 a.m.-9:05 a.m.) September 11, 2001 and 8:54 a.m.-8:55 a.m. September 11, 2001) and are in the training area from 9:09 a.m. to 9:13 a.m. (see 9:09 a.m.-9:13 a.m. September 11, 2001).

The two F-15 fighter jets launched from Otis Air National Guard Base in response to the hijacked Flight 11 (see 8:46 a.m. September 11, 2001) are given guidance by an air traffic controller at the FAA’s Boston Center on flying into military airspace over the Atlantic Ocean, and then discuss details of their intended hold in that airspace with another Boston Center controller. [9/11 Commission, 2004; 9/11 Commission, 2004]
Fighters Heading into Training Area - Lieutenant Colonel Timothy Duffy, the pilot of one of the fighters, talks over radio with the Boston Center controller who is working at the Cape Sector radar position. Duffy says the two fighters are “proceeding [on] our present heading of 250 for about 100 miles,” and adds that “Huntress”—the call sign for NORAD’s Northeast Air Defense Sector (NEADS)—“wants us to hold just south of Long Island, to see if we can get any more assistance.” The controller replies: “Okay, that’s fine. You are heading into the warning area.” [Federal Aviation Administration, 9/11/2001] By the “warning area,” he is referring to a military airspace training area over the Atlantic, just south of Long Island, known as “Warning Area 105” or “Whiskey 105.” [9/11 Commission, 9/22/2003 pdf file; Spencer, 2008, pp. 85] The original flight strip for the two F-15s gave a destination of New York’s JFK International Airport, but the fighters have recently been redirected (see 8:54 a.m.-8:55 a.m. September 11, 2001). [9/11 Commission, 9/22/2003 pdf file; 9/11 Commission, 9/24/2003; 9/11 Commission, 2004]
Fighters Told They Can Contact Navy Control Facility - The controller continues, “If you want, if you can’t contact me, you can go to Giant Killer on 338.1.” [Federal Aviation Administration, 9/11/2001] (“Giant Killer” is the call sign for the Fleet Area Control and Surveillance Facility in Virginia Beach, Virginia—a Navy air traffic control agency that handles over-water military operations. [New York Times, 2/10/1997; Spencer, 2008, pp. 143] ) The controller then tells Duffy that he can contact Giant Killer, because “you’re going through their airspace.” Duffy replies, “Okay, I’ll do all that, thanks.” [Federal Aviation Administration, 9/11/2001] The Otis fighters are then handed on to another controller at the Boston Center. Stephen Roebuck, who is working at the Hampton Sector radar position, now communicates with them. [9/11 Commission, 9/22/2003 pdf file; 9/11 Commission, 2004] The Hampton Sector covers the area that includes the Whiskey 105 airspace.
Pilots Unable to Give Specific Information about 'Hold' - Roebuck asks the pilots of the fighters if they know their destination. They reply no, and say they need to hold in the western area of Whiskey 105. Roebuck wants information on the position they will hold at in Whiskey 105, but the pilots say they cannot give a specific location. Instead, they tell Roebuck to keep them in a “published hold” in the area. Roebuck asks if the fighters want a “radial” or a “latitude/longitude” hold, but is told they will maintain themselves.
Controller Finds Fighters' Unspecific 'Hold' Unusual - Due to the lack of information the pilots have provided him with, Roebuck is unsure what the fighters are going to do, and does not know how to clear airspace for their potential course. Roebuck will tell the 9/11 Commission that “normally, clearing area for fighters is very specific, so this unknown generic hold [is] extremely unusual. The fighters had an altitude, but did not issue an EFC [expect further clearance].” He assumes the purpose of the generic hold is that “if the fighters needed to move rapidly, they did not want to be encumbered by an air traffic technicality.” [9/11 Commission, 9/22/2003 pdf file; 9/11 Commission, 9/24/2003]

An announcement is made over the public address system in the South Tower of the World Trade Center, advising workers that they can begin an orderly evacuation of the building if conditions warrant it. [New York Times, 5/17/2004; 9/11 Commission, 7/24/2004, pp. 289] A previous announcement over the public address system instructed people in the South Tower to stay in, or return to, their offices, rather than evacuate (see (8:50 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 287-288; Dwyer and Flynn, 2005, pp. 72] The new announcement begins: “May I have your attention, please. Repeating this message: the situation occurred in Building 1 [i.e. the North Tower].” The announcer then says, “If the conditions warrant on your floor, you may wish to start an orderly evacuation.” [New York Times, 5/17/2004] The announcement is presumably made by Philip Hayes, the deputy fire safety director on duty at the fire command desk in the lobby of the South Tower. A button at the desk enables fire safety directors to deliver announcements over the public address system. [Dwyer and Flynn, 2005, pp. 26]
Identity of Person Who Ordered Evacuation Unclear - The new advice, for tenants to evacuate, does “not correspond to any prewritten emergency instruction,” according to the 9/11 Commission Report. [9/11 Commission, 7/24/2004, pp. 289] It is unclear who told Hayes to make the announcement giving this advice. George Tabeek, the Port Authority’s security manager for the WTC, contacted the fire command desks in the Twin Towers immediately after Flight 11 hit the North Tower, with instructions about what to do. His orders for Hayes, however, were to “keep people inside the South Tower” (see Shortly After 8:46 a.m. September 11, 2001). [New Jersey Star-Ledger, 9/6/2011]
Police Commander Called for Evacuation of WTC - Captain Anthony Whitaker, the Port Authority Police Department (PAPD) commanding officer at the WTC, called for the evacuation of the WTC at 9:00 a.m. (see 8:59 a.m.-9:02 a.m. September 11, 2001). However, his instruction was given over PAPD radio channel W, “which could not be heard by the deputy fire safety director in the South Tower,” according to the 9/11 Commission Report. [Murphy, 2002, pp. 184-185; 9/11 Commission, 7/24/2004, pp. 293; National Institute of Standards and Technology, 9/2005, pp. 201] Furthermore, according to the Port Authority, deputy fire safety directors do not generally take direct orders from the PAPD under the regular chain of command. Therefore, the 9/11 Commission Report will state, it is “not known if [Hayes] received the order by the PAPD to evacuate the complex.” [9/11 Commission, 7/24/2004, pp. 544]
Fire Department Responsible for Ordering Evacuations - According to New York Times reporters Jim Dwyer and Kevin Flynn, “The authority to order an evacuation during a fire normally rests with the fire department.” [Dwyer and Flynn, 2005, pp. 79] In a phone call with his counterpart in the North Tower, at 8:49 a.m., Hayes in fact said he would wait to hear from “the boss from the fire department or somebody” before ordering an evacuation of the South Tower (see 8:49 a.m. September 11, 2001). [Port Authority of New York and New Jersey, 9/11/2001 pdf file; 9/11 Commission, 7/24/2004, pp. 287; Dwyer and Flynn, 2005, pp. 27] But whether someone from the fire department told Hayes to order an evacuation is unknown. It is also unclear how long announcements, advising an evacuation, continue for. Hayes and his counterpart in the North Tower are “making announcements that the situation was serious and that occupants should evacuate immediately” for “[a]s long as the [fire alarm system] was still operational,” according to Fire Engineering magazine. [Fire Engineering, 11/1/2002] However, the 9/11 Commission Report will state, “Evidence suggests that the public address system [in the South Tower] did not continue to function after the building was hit.” This would mean no announcements go out after 9:03 a.m., when Flight 175 hits the tower (see 9:03 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 295] By the time the South Tower collapses (see 9:59 a.m. September 11, 2001), out of around 8,540 people who were originally in the building, 7,940 (93 percent) have made it out and will survive, according to the National Institute of Standards and Technology.

Flight 175 hits the WTC South Tower. The picture was taken from a traffic helicopter.Flight 175 hits the WTC South Tower. The picture was taken from a traffic helicopter. [Source: WABC 7/ Salient Stills]Flight 175 hits the South Tower of the World Trade Center (Tower Two). Seismic records pinpoint the time at six seconds before 9:03 a.m. (rounded to 9:03 a.m.). Hijackers Marwan Alshehhi, Fayez Ahmed Banihammad, Mohand Alshehri, Hamza Alghamdi, and Ahmed Alghamdi presumably are killed instantly, and many more in the tower will die over the next few hours. [New York Times, 9/12/2001; CNN, 9/12/2001; CNN, 9/17/2001; North American Aerospace Defense Command, 9/18/2001; USA Today, 12/20/2001; Federal Emergency Management Agency, 5/1/2002, pp. 1-10; New York Times, 5/26/2002; Associated Press, 8/21/2002; USA Today, 9/2/2002] According to the NIST report, the crash time is 9:02:59. [National Institute of Standards and Technology, 9/2005, pp. 38] According to the 9/11 Commission Report, the crash time is 9:03:11. [9/11 Commission, 7/24/2004, pp. 8] Millions watch the crash live on television. The plane strikes the 77th through 85th floors in the 110-story building. Approximately 100 people are killed or injured in the initial impact; 600 people in the tower eventually die. The death toll is far lower than in the North Tower because about two-thirds of the South Tower’s occupants have evacuated the building in the 17 minutes since the first tower was struck. [USA Today, 12/20/2001; National Institute of Standards and Technology, 9/2005, pp. 5-9, 41] The combined death toll from the two towers is estimated at 2,819, not including the hijackers. [Associated Press, 8/21/2002] The impact severs some columns on the south side of the South Tower. Each of the Twin Towers is designed as a “tube-in-tube” structure and the steel columns which support its weight are arranged around the perimeter and in the core. The plane, which is traveling at an estimated speed of around 500 mph (see October 2002-October 2005), severs 33 of the building’s 236 perimeter columns and damages another one. [National Institute of Standards and Technology, 9/2005, pp. 39] The perimeter columns bear about half of the tower’s weight, so the damage to them reduces the tower’s ability to bear gravity loads by about 7.1 percent. [National Institute of Standards and Technology, 9/2005, pp. 6] The actual damage to the 47 core columns is not known, as there are no photographs or videos of it, but there will be much speculation about this after 9/11. It will be suggested that some parts of the aircraft may be able to damage the core even after crashing through the exterior wall (see 8:46 a.m. September 11, 2001). [National Institute of Standards and Technology, 9/2005, pp. 107] According to NIST’s base case model, five of the core columns are severed and another five suffer some damage. [National Institute of Standards & Technology, 9/2005, pp. 235 pdf file] This may reduce the tower’s ability to bear loads by a further approximately 8 percent, meaning that the aircraft impact accounted for a loss of about 15 percent of the building’s strength. This damage will be cited as an event contributing to the building’s collapse after 9/11 (see October 23, 2002 and October 19, 2004). NIST’s base case estimate of damage to the North Tower’s core will be similar, even though the aircraft impact there was dissimilar (see 8:46 a.m. September 11, 2001). Flight 11 hit the North Tower’s core head on, whereas Flight 175 only hits the corner of the South Tower’s core. [National Institute of Standards and Technology, 9/2005, pp. 20-23, 38-41] In addition, some of the fireproofing on the steel columns and trusses may be dislodged (see 8:46 a.m. September 11, 2001). [National Institute of Standards & Technology, 9/2005, pp. xxxvi, 83 pdf file] Photographs and videos of the towers will not show the state of fireproofing inside the buildings, but the National Institute of Standards and Technology (NIST) will try to estimate the damage to fireproofing using a series of computer models. Its severe case model (see (October 2002-October 2005)) will predict that 39 of the 47 core columns are stripped of their fireproofing on one or more floors and that fireproofing is stripped from trusses covering 80,000 ft2 of floor area, the equivalent of about two floors. NIST will say that the loss of fireproofing is a major cause of the collapse (see April 5, 2005), but only performs 15 tests on fireproofing samples (see October 26, 2005). [National Institute of Standards and Technology, 9/2005, pp. 41] According to NIST, less fireproofing is stripped from the North Tower (see 8:46 a.m. September 11, 2001).

Two officers in the Air Traffic Services Cell (ATSC)—a small office at the FAA’s Command Center in Herndon, Virginia, manned by military reservists—contact the National Military Command Center (NMCC) at the Pentagon, to ask about military assistance in response to the terrorist attacks. [US Air Force, 9/11/2001; Aviation Week and Space Technology, 6/10/2002; 9/11 Commission, 4/14/2004]
Military Leaders 'in a Meeting to Determine Their Response' - Apparently shortly after the south World Trade Center tower is hit at 9:03 a.m., Ben Sliney, the national operations manager at the Command Center, asks the ATSC for a military response to the ongoing events (see 9:06 a.m. and After September 11, 2001). Therefore, Lieutenant Colonel Michael-Anne Cherry, one of the three officers on duty in the ATSC, calls the NMCC. However, according to a chronology of the ATSC’s actions on this day, Cherry is told that “senior leaders” at the NMCC are “in a meeting to determine their response” to the attacks, and will call back.
Second Officer Calls NMCC, Told Fighters Have Been Launched - Then, at around 9:08 a.m., Sliney talks to another of the officers on duty in the ATSC, Colonel John Czabaranek, and asks if fighter jets have been launched toward New York. [US Air Force, 9/11/2001; 9/11 Commission, 4/14/2004] Two F-15s have already taken off from Otis Air National Guard Base, Massachusetts, toward the New York area (see 8:46 a.m. September 11, 2001), but, according to the 9/11 Commission, “Lacking a target,” these fighters have been “vectored toward military-controlled airspace off the Long Island coast” (see (8:53 a.m.-9:05 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] In response to Sliney’s inquiry, Czabaranek calls the NMCC. The NMCC indicates that it is aware of the request for fighter support, and says aircraft have been scrambled from Otis Air Base. Czabaranek passes this information on to Sliney, telling him that fighters are en route.
ATSC's Secure Phones Initially Not Working - According to the chronology of the ATSC’s actions, the unit’s secure phones do not work for an incoming call from the NMCC that is apparently made shortly after 9:03 a.m. The ATSC’s keys for its secure phones are recalibrated, and the phones then “worked fine.” [US Air Force, 9/11/2001; 9/11 Commission, 4/14/2004]

The FAA’s Boston Center notifies the two fighter jets launched from Otis Air National Guard Base in response to the hijacked Flight 11 (see 8:46 a.m. September 11, 2001) that a second aircraft has been hijacked, and then tells the fighters of the second crash at the World Trade Center. The fighters are currently flying into a military training area over the Atlantic Ocean, just south of Long Island, known as “Whiskey 105” (see 9:01 a.m. September 11, 2001). They are being handled by Boston Center air traffic controller Stephen Roebuck.
Pilots Told of Second Hijacking and Crash - Roebuck asks the pilots of the fighters if they are in contact with “company,” meaning the military, and they say they are. He then informs them of the report of a second aircraft being hijacked. [9/11 Commission, 9/22/2003 pdf file; 9/11 Commission, 9/24/2003; 9/11 Commission, 2004] However, one of the pilots, Major Daniel Nash, will later say he is not told the call sign of this second hijacked aircraft, “UAL 175, until after he landed.” [9/11 Commission, 10/14/2003 pdf file] Roebuck hears from a colleague at the Boston Center that a second plane has hit the WTC. Just before 9:08 a.m., he notifies the Otis pilots of this. Roebuck will recall that he tries to communicate this “second event” to them calmly. [9/11 Commission, 9/22/2003 pdf file; 9/11 Commission, 9/24/2003; 9/11 Commission, 2004]
Pilot Switches into 'Combat Mode' - Lieutenant Colonel Timothy Duffy, the other Otis pilot along with Nash, will later recall his response to the news of the second crash, saying: “I look up and we’re about 60 or 70 miles outside Manhattan, and I can see the towers burning.… Okay, obviously everything just changed from my personal mind-set. We take off to go help somebody, and now as I look up and can see the burning I say, ‘Okay, now people are dying.’ It’s kind of hard to explain, but basically you switch into a combat mode where you say, ‘Okay, this just got real serious real fast.‘… Now people are dying and you’re thinking, ‘Okay, what do I have to do?’ And you have to put emotion aside because you don’t have time for it.” [Filson, 2003, pp. 60] Both pilots will later claim that prior to learning of the second hijacking and the second crash, they had been unaware that the first hijacked plane, Flight 11, had hit the WTC. [Filson, 10/2/2002; Filson, 10/22/2002; 9/11 Commission, 10/14/2003 pdf file; 9/11 Commission, 1/7/2004 pdf file] However, recordings of communications at the Boston Center reveal that Duffy was told of that first crash at 8:55 a.m. (see 8:55 a.m. September 11, 2001). [Federal Aviation Administration, 9/11/2001; 9/11 Commission, 2004] Duffy and Nash are also told about the second crash by someone at NORAD’s Northeast Air Defense Sector (NEADS) around this time (see (9:03 a.m.) September 11, 2001).

Laura Bush, the president’s wife, leaves the White House in her limousine, on her way to Capitol Hill where she is scheduled to testify before a Congressional committee, but she is unaware that a second plane has crashed into the World Trade Center. [Us Weekly, 10/15/2001; National Journal, 8/31/2002; Bush, 2010, pp. 198] Bush is set to appear before the Senate Committee on Health, Education, Labor, and Pensions, where she will talk about early childhood education. [CNN, 9/12/2001; CNN, 9/11/2002] She was informed of the first crash at the WTC by her lead Secret Service agent as she was getting into her limousine (see (8:55 a.m.) September 11, 2001).
First Lady Unaware of Second Crash - The limousine leaves the White House at 9:07 a.m., according to Noelia Rodriguez, the first lady’s press secretary. [National Journal, 8/31/2002] The second aircraft, Flight 175, hit the WTC four minutes earlier (see 9:03 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 8] However, Bush and those with her in the limousine are unaware of this. [Bush, 2010, pp. 197-198]
First Lady Thinks about Canceling Hearing - Nevertheless, Bush already thinks the Senate hearing she is on her way to should perhaps be canceled, because New York Senator Hillary Clinton is on the education committee and is therefore supposed to attend. Bush will comment, “Even after the first [crash], when I thought it was just an accident, I thought we probably should cancel, because Mrs. Clinton was on the committee and she’s from New York, and she’d probably want to rush home at that time.” [USA Today, 9/10/2001; Gerhart, 2004, pp. 162] All the same, Bush continues with the two-mile journey from the White House to Capitol Hill. She will learn of the second crash, and realize this is a terrorist attack, shortly before arriving at the Russell Senate Office Building, where the hearing is set to take place (see (9:14 a.m.) September 11, 2001).
Secret Service Allows Bush to Head to Event - Members of Bush’s Secret Service detail apparently raise no objection to Bush going ahead with her trip to Capitol Hill. [CNN, 9/11/2002; Gerhart, 2004, pp. 162; Bush, 2010, pp. 198] The Secret Service is responsible for protecting the first lady, and she is considered to be one of the nation’s “most visible targets.” [US Department of the Treasury, 5/8/2001; Office of Management and Budget, 7/2001, pp. 82 pdf file] The agency’s mission includes keeping her “in sight and out of harm’s way,” according to a book about the Secret Service by author Philip Melanson.

The two F-15 fighter jets launched from Otis Air National Guard Base in response to Flight 11 (see 8:46 a.m. September 11, 2001) have been directed to “Whiskey 105,” a military airspace training area over the Atlantic Ocean, just south of Long Island. According to the 9/11 Commission, “To avoid New York area air traffic and uncertain about what to do, the fighters were brought down to military airspace to ‘hold as needed.’ From 9:09 to 9:13, the Otis fighters stayed in this holding pattern.” [9/11 Commission, 7/24/2004, pp. 20; Spencer, 2008, pp. 85] Otis pilot Major Daniel Nash will later comment, “Neither the civilian controller or the military controller knew what they wanted us to do.” [Cape Cod Times, 8/21/2002]
'Pushback' from FAA Controllers - By 9:08 a.m., Major Kevin Nasypany, the NEADS mission crew commander, had learned of the second World Trade Center crash and wanted to send the Otis fighters to New York City. However, according to Vanity Fair, the NEADS “weapons techs get ‘pushback’ from civilian FAA controllers, who have final authority over the fighters as long as they are in civilian airspace. The FAA controllers are afraid of fast-moving fighters colliding with a passenger plane, of which there are hundreds in the area, still flying normal routes.” [9/11 Commission, 8/26/2004, pp. 25; Vanity Fair, 8/1/2006] Author Lynn Spencer will add: “[L]ocal FAA controllers are busy shutting down New York’s airspace and are less than eager to grant the fighters access to the civilian airspace. They’re afraid of fast-moving fighters colliding with the hundreds of airliners that are still in the area. Many of those flights are doing unpredictable things just now, such as canceling their flight plans and changing course, and controllers are not convinced that they can provide adequate separation if fast-moving fighters are added to the mix. They just need a few more minutes, they keep saying.”
New York Center Not Answering Phone - Nasypany tries contacting the military liaison at the FAA’s New York Center, but no one is answering the phone. According to Spencer, “He wants the Otis fighters over New York, not in military airspace 100 miles off the coast, but he has little choice. Without permission from the FAA to penetrate the civil airspace over New York, NEADS must advise the Otis F-15 pilots… to continue to remain clear of the city.” [Spencer, 2008, pp. 111-112]
Director Wants Jets 'Closer In' - At 9:10 a.m., the senior director on the NEADS operations floor tells the weapons director, “I want those fighters closer in.” [9/11 Commission, 7/24/2004, pp. 459] NEADS weapons controller Major Steve Hedrick asks Major James Fox, the weapons team leader, “Can we give [the fighters] a mission?” Fox replies, “Right now their mission is to hold.” [Spencer, 2008, pp. 111] Then, at around 9:11 a.m., either the senior weapons director at NEADS or his technician instructs the Otis fighters to “remain at current position [holding pattern] until FAA requests assistance.”
Fighters Exit Holding Pattern for New York - Just before 9:13 a.m., the Otis pilots tell their controller at the FAA’s Boston Center that they need to establish a combat air patrol over New York. [9/11 Commission, 7/24/2004, pp. 459] According to the 9/11 Commission, “Radar data show that at 9:13, when the Otis fighters were about 115 miles away from the city, the fighters exited their holding pattern and set a course direct for Manhattan” (see 9:13 a.m. September 11, 2001).

[Source: Publicity photo]The United Airlines dispatch operations manager speaks with the American Airlines dispatch operations manager, and they discuss the two plane crashes in New York. [9/11 Commission, 8/26/2004, pp. 25] Mike Barber, the United dispatch manager, is at the airline’s System Operations Control (SOC) center, just outside Chicago, while Craig Parfitt, the American dispatch manager, is at that airline’s SOC center in Fort Worth, Texas. [Wall Street Journal, 10/15/2001] At 9:10, United Airlines is aware a second aircraft has hit the World Trade Center, but it does not realize this is one of its own flights. During their call, Parfitt says to Barber he believes both the aircraft that hit the WTC belonged to American Airlines. (At 9:08 a.m., officials at American Airlines’ SOC mistakenly concluded the second aircraft to hit the WTC might have been Flight 77 (see 9:08 a.m. September 11, 2001).) But Barber says he is increasingly “confident” that the second plane was United Airlines Flight 175. “In slow motion and enlarged images of the second impact on CNN, he could see that the airplane did not have the shiny metallic color of American jets.” By 9:20, according to the 9/11 Commission, although Barber believes the second crashed plane was Flight 175, the identity of this aircraft is “still unconfirmed.” [9/11 Commission, 8/26/2004, pp. 25-26]

NORAD’s Northeast Air Defense Sector (NEADS) declares “AFIO” (Authorization for Interceptor Operations) for New York airspace, which gives the military authority over the FAA for that airspace, and will enable the fighter jets launched from Otis Air National Guard Base in response to Flight 11 (see 8:46 a.m. September 11, 2001) to head toward the city. [Spencer, 2008, pp. 113] For the last few minutes, the two Otis fighters have been kept in a “holding pattern” in military airspace over the Atlantic Ocean (see 9:09 a.m.-9:13 a.m. September 11, 2001), and NEADS has been unable to get permission from the FAA for them to enter the civilian airspace over New York. [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 111-112]
Marr Wants AFIO - According to author Lynn Spencer, Colonel Robert Marr, the NEADS battle commander, now “decides that he is done waiting for FAA approval for his fighters to enter New York airspace.… He will play his ace card. There is one method for the military to override the FAA’s authority over the airspace, and it is called AFIO.” The declaration of AFIO will give the military “emergency authority to enter FAA-controlled airspace without permission.” [Spencer, 2008, pp. 113] According to an FAA document, “Upon declaring ‘AFIO,’ NORAD assumes responsibility for [interceptor fighter jets] seeing and avoiding all known aircraft and ensuring safe intercept conduct.” [Federal Aviation Administration, 2/19/2004, pp. 4-12-1 - 4-12-2]
Nasypany Directed to Declare AFIO - Marr, who is in the NEADS battle cab, speaks over a direct phone line to Major Kevin Nasypany, the NEADS mission crew commander, who is on the operations floor there. He orders him to declare AFIO for New York airspace and to immediately move the Otis fighters over the city. Nasypany then calls out across the operations floor to the weapons team, “Okay, we’re declaring AFIO at this time.” The directive is relayed immediately to the two Otis pilots, who will then leave their holding pattern and head toward Manhattan (see 9:13 a.m. September 11, 2001).

The jet fuel that spilled from Flight 175 when it hit the South Tower (see 9:03 a.m. September 11, 2001) has mostly burned up by this time. The National Institute of Standards and Technology (NIST), which later investigates the collapses, will say the “initial jet fuel fires themselves lasted at most a few minutes.” [National Institute of Standards and Technology, 9/2005, pp. 183] Engineering professor Forman Williams will say the jet fuel “burned for maybe 10 minutes.” [Popular Mechanics, 3/2005] Flight 175, a Boeing 767, had a capacity of 23,980 gallons, but was only carrying about 9,100 gallons of fuel when it hit the WTC. NIST will estimate that less than 1,500 gallons were consumed in a fireball inside the tower and 910 to 2,275 gallons were consumed in the fireballs outside the building. Approximately 6,100 gallons therefore splashed onto the office furnishings and started fires on various floors. However, after the jet fuel is used up, office fires burn until the building collapses. NIST will calculate that there were about four pounds per square foot of combustibles in the office space, or about 60 tons per floor. Offices in the WTC actually had fewer combustibles than other similar spaces due to the small number of interior walls and limited bookshelf space. NIST will later find that only three of sixteen perimeter columns it recovers reached a temperature of 250°C and neither of the two core columns it retrieves reached this temperature. NIST will also find that none of the samples it acquires reached a temperature above 600°C (see August 27, 2003). While steel does not melt until its temperature is about 1,600°C, it may begin to lose significant strength at over 500°C. [National Institute of Standards and Technology, 9/2005, pp. 29, 38, 42, 77] The jet fuel also burned up in the North Tower about 10 minutes after it was hit (see 8:57 a.m. September 11, 2001). When a group of firefighters reach the bottom impact floor in the South Tower just before collapse, they only find two isolated fires (see 9:52 a.m. September 11, 2001).

Noelia Rodríguez.Noelia Rodríguez. [Source: Harvard University]Laura Bush, the president’s wife, is told that a second plane has crashed into the World Trade Center and realizes this is a terrorist attack while she is being driven from the White House to Capitol Hill, where she is scheduled to testify before a Congressional committee. [Us Weekly, 10/15/2001; CNN, 9/11/2002; Bush, 2010, pp. 197-198] Bush is set to appear before the Senate Committee on Health, Education, Labor, and Pensions at 10:00 a.m., where she will talk about early childhood education. [USA Today, 9/10/2001; CNN, 9/12/2001; CNN, 9/11/2002] Her lead Secret Service agent informed her of the first crash at the WTC as she was getting into her limousine, outside the White House, but she’d thought the crash was an accident (see (8:55 a.m.) September 11, 2001). [National Journal, 8/31/2002; Gerhart, 2004, pp. 162]
First Lady Told of Second Crash, Knows It Is Terrorism - The Secret Service agents traveling with Bush now tell the first lady about the second crash at the WTC while her limousine is driving up Pennsylvania Avenue, approaching Capitol Hill. “The car fell silent; we sat in mute disbelief,” Bush will later recall. “One plane might be a strange accident; two planes were clearly an attack.” She will note, “We knew then that it was terrorism.” [CNN, 9/11/2002; Bush, 2010, pp. 198]
Members of First Lady's Staff Learn of Crash - Members of Bush’s staff also learn about the second crash around this time, while they are on their way to Capitol Hill. Ashleigh Adams, the first lady’s deputy press secretary, learns of it while traveling in the press van. “It must have been only a couple of minutes after we departed the White House,” Adams will recall, “that the reporters’ and photographers’ pagers and cell phones started to go off, and someone shouted to me, ‘Ashleigh, the second Twin Tower was hit.’” Adams calls Noelia Rodriguez, the first lady’s press secretary, who is traveling in the staff van, and tells her the news. After Rodriguez arrives on Capitol Hill, she will jump out of the staff van, run to Bush’s limousine, and get inside. But she will find that the first lady has already been informed of the second crash. [National Journal, 8/31/2002]
First Lady Learns of Crash 11 Minutes after It Occurs - Bush will recall that she arrives at the Russell Senate Office Building, where the hearing she is set to attend is supposed to take place, two minutes after she is told about the second crash, at 9:16 a.m., meaning she learns of the crash at 9:14 a.m. [Bush, 2010, pp. 198] This is 11 minutes after the second plane, Flight 175, hit the WTC (see 9:03 a.m. September 11, 2001).

Otis Air National Guard Base at Cape Cod, Massachusetts, begins preparing all of its available fighter jets to take off. [102nd Fighter Wing, 2001; Spencer, 2008, pp. 155] The base has already launched its two F-15s that are kept on alert, in response to the hijacking of Flight 11 (see 8:46 a.m. September 11, 2001). [Cape Cod Times, 8/21/2002; 9/11 Commission, 7/24/2004, pp. 20] After the second attack on the World Trade Center at 9:03 a.m., commanders at the base convened and decided to recall all aircraft out on training, and begin loading fuel and weapons onto all available fighters (see Shortly After 9:03 a.m. September 11, 2001). [Spencer, 2008, pp. 153-154]
Officer Ordered to Prepare Fighters - Jeff Isch, the weapons supervisor for the 102nd Fighter Wing, which is based at Otis, will later recall, “As soon as that second tower was hit, we all started to scramble to action.” [Cape Cod Times, 9/8/2002] However, author Lynn Spencer will indicate that the base does not begin preparing fighters to launch until about 10 to 15 minutes later. She will write that the aircraft maintenance squadron officer, whose job is to get aircraft ready for combat, has been awaiting orders since the time of the second crash. Then, “Less than 15 minutes after the second impact into the World Trade Center, the order came.” An officer from the base’s battle cab gives him the instruction, “Listen, I want you to generate as many airframes [i.e. fighter jets] as you can!” Immediately, the aircraft maintenance squadron officer starts directing all available workers to the flight line (the parking and servicing area for aircraft) to prepare the base’s available F-15s for combat. [Spencer, 2008, pp. 155]
Base Personnel Load Aircraft with Weapons - A report written by the 102nd Fighter Wing’s historian will describe: “Operations [personnel] along with maintenance [personnel] did a survey of which aircraft had bullets loaded and prioritized those aircraft to be first on status. They immediately began to pre-position wing tanks to increase range for future flights. Munitions started flowing at 9:30 and the aircraft were loaded with a mix of different types of weapons.” [102nd Fighter Wing, 2001] Isch’s crew hurries to fix fighters with live weapons. Some aircraft are fitted with newer missiles that are rarely pulled out. [Cape Cod Times, 9/8/2002] According to Boston Magazine, “Jets undergoing maintenance [are] rushed back into service, fitted out for combat instead of training.” [Boston Magazine, 1/2002]
Fighters Recalled from Training Mission and Armed - A number of the 102nd Fighter Wing’s F-15s are away for a training mission over the Atlantic Ocean (see (9:00 a.m.-9:24 a.m.) September 11, 2001). [102nd Fighter Wing, 2001; Cape Cod Times, 9/11/2006] At 9:25 a.m., these fighters will be instructed to return to their base and will land back at Otis around 20 minutes later (see (9:25 a.m.-9:45 a.m.) September 11, 2001). [9/11 Commission, 10/14/2003 pdf file; Spencer, 2008, pp. 155; Airman, 9/3/2011] Two of the aircraft have mechanical problems and will therefore be unable to fly again immediately. But the other fighters will be refueled and loaded with 940 rounds of 20 mm bullets. [102nd Fighter Wing, 2001] The first F-15s to subsequently take off from Otis Air Base will launch at around 10:30 a.m. (see (10:30 a.m.) September 11, 2001 and (Shortly After 10:30 a.m.) September 11, 2001). [9/11 Commission, 10/14/2003 pdf file; Spencer, 2008, pp. 244-246] Fourteen of the base’s fighters are “mission capable” by the end of the day, according to Technical Sergeant Michael Kelly, the full-time technician in the command post at Otis Air Base. [9/11 Commission, 10/14/2003 pdf file] But according to Spencer, by 6:00 p.m., 21 of the 24 F-15s that are stationed at Otis Air Base will be airborne. [Spencer, 2008, pp. 281]

Bill Halleck, an American Airlines air traffic control specialist at the airline’s System Operations Control (SOC) in Fort Worth, Texas, phones an official at the FAA’s Herndon Command Center, to ask about the status of New York City air traffic. During their two-and-a-half minute conversation, Halleck says American thinks Flight 11 crashed into the WTC, and says that Flight 77 is “missing.” Presently, he receives an update from someone else at SOC, indicating that Flight 77 may also have crashed into the WTC (see 9:08 a.m. September 11, 2001). He wonders how it could have gotten to New York, but updates the FAA official on this news. The FAA official replies that the second WTC crash may not have been Flight 77 because “we have another call sign” for that incident. The FAA Command Center is currently uncertain of the identity of either of the planes that hit the Twin Towers, and provides no further information. [9/11 Commission, 8/26/2004, pp. 31 and 94]

Brian Wilson.Brian Wilson. [Source: Publicity photo]There is apparently no increase in the level of security at the Capitol building in Washington, DC, even though First Lady Laura Bush has arrived at the nearby Russell Senate Office Building and more than 10 minutes have passed since a second plane hit the World Trade Center. [Gilbert et al., 2002, pp. 64; 9/11 Commission, 7/24/2004, pp. 8; Bush, 2010, pp. 198] At 9:16 a.m., Bush arrived at the Russell Senate Office Building, located just north of the Capitol building, where she was scheduled to testify before a Senate committee at 10:00 a.m. [USA Today, 9/10/2001; CNN, 9/12/2001; Bush, 2010, pp. 198]
Reporter Sees No Signs of Increased Security - The first lady is considered one of the nation’s “most visible targets,” and, as one of the Secret Service’s “permanent protectees,” like the president, she has a detail of special agents assigned to her. [US Department of the Treasury, 5/8/2001; Office of Management and Budget, 7/2001, pp. 82 pdf file; United States Secret Service, 2002] And yet, even though Bush has arrived on Capitol Hill, and over 10 minutes have passed since the second aircraft hit the WTC (see 9:03 a.m. September 11, 2001), there is apparently no increase in the level of security at the Capitol building. Fox News correspondent Brian Wilson will later recall that when reporting from the Capitol building around this time, he is “talking about the first lady being in the Capitol and saying that I had not seen any signs of tighter security in the building.”
Reporter Surprised at Plan to Hold a Photo Op - Wilson is also surprised that, although the Senate hearing Bush was scheduled to attend has been canceled, the first lady is still going to make a public appearance. He will comment that “they were (incredibly) trying to set up a brief photo opportunity.” [Gilbert et al., 2002, pp. 64; 9/11 Commission, 7/24/2004, pp. 8] (Wilson is presumably referring to Laura Bush’s appearance before reporters and cameras alongside Senators Edward Kennedy (D-MA) and Judd Gregg (R-NH), which takes place at 9:41 a.m. (see 9:41 a.m. September 11, 2001).

A meeting is held in the office of Carl Truscott, the Secret Service special agent in charge of the presidential protective division (PPD), during which Truscott and three other senior Secret Service agents discuss security enhancements at the White House. Truscott, who is responsible for the overall security of the White House, will later say that he contacted the three other agents after watching “the CNN broadcast of the aircraft crashing into the World Trade Center,” and asked them to come to his office in the Eisenhower Executive Office Building, next to the White House (see (After 8:48 a.m.) September 11, 2001). The names of these agents are unstated, but they are a deputy special agent in charge of the PPD, an assistant to the special agent in charge of the PPD, and an assistant division chief of the Secret Service’s technical security division. Their meeting begins at “approximately 9:18 a.m.,” according to Truscott. [United States Secret Service, 10/1/2001]
Agents Discuss Measures to Increase Security - Truscott and the other agents briefly discuss the Secret Service assets that have so far been deployed in response to the crisis. [United States Secret Service, 9/12/2001] Issues that are addressed during the meeting, according to Truscott, include placing counter-sniper support on the White House; placing counter-surveillance units near the White House; opening the Emergency Operations Center; increasing the number of emergency response teams; increasing technical security division support; providing counter-assault team support to First Lady Laura Bush’s Secret Service detail at the US Capitol building; providing protection for National Security Adviser Condoleezza Rice; and alerting the Army Corps of Engineers structural collapse team.
Agent Learns of Aircraft Approaching Washington - While the meeting is taking place, Truscott receives a call from Danny Spriggs, an agent at the Secret Service’s headquarters in Washington, DC, informing him that a suspicious aircraft is flying toward the capital (see (Shortly After 9:35 a.m.) September 11, 2001). And while he is on the phone with Spriggs, Truscott receives a call from a “White House security representative.” During that call, Truscott instructs the security representative to evacuate the White House. [United States Secret Service, 10/1/2001] (The White House will begin evacuating at around 9:45 a.m. (see (9:45 a.m.) September 11, 2001). [Associated Press, 2001 pdf file; CNN, 9/12/2001] )
Agent Suggests Going to White House Bunker - At some point, Truscott suggests that those at the meeting go to the Presidential Emergency Operations Center (PEOC), a bunker below the White House. Truscott will subsequently head to the PEOC. Apparently at least one other person at the meeting—the assistant division chief of the technical security division—will head there with him. [United States Secret Service, 9/12/2001] On his way to the PEOC, Truscott will meet Rice in the White House Situation Room and accompany her down to the PEOC (see (9:45 a.m.) September 11, 2001). [United States Secret Service, 10/1/2001] Presumably as a result of the meeting in Truscott’s office, the Secret Service will implement “a number of security enhancements around the White House complex,” according to the 9/11 Commission Report (see (After 9:18 a.m.) September 11, 2001).

Personnel on the operations floor at NORAD’s Northeast Air Defense Sector (NEADS) confirm to their mission crew commander (MCC) that they are prepared to issue an order to fighter pilots, telling them to fire on a commercial airliner.
MCC Concerned about Possible Shootdown - Major Kevin Nasypany, the NEADS MCC, is concerned about what might happen next as the day’s crisis unfolds. He realizes he may need to order fighter jets under his command to shoot down an errant aircraft. He therefore starts walking up and down the operations floor, impatiently asking all his section heads and weapons technicians, “Are you prepared to follow an order to shoot down a civilian airliner?” All of them affirm that they will issue such an order if required to do so.
Nasypany Confers with Marr - Satisfied with their answers, Nasypany gets on the phone to Colonel Robert Marr, who is in the NEADS battle cab, and asks him, “Have we already asked the questions?” What Nasypany means is, have they asked about getting authorization to take out a threatening aircraft? According to author Lynn Spencer, “Those authorizations, [Nasypany] knows, are going to have to come from the president himself, passed down from senior NORAD command in Colorado Springs.” Marr replies that Major General Larry Arnold, who is at the Continental US NORAD Region (CONR) headquarters in Florida, is seeking the necessary authorizations and is prepared to take any action required. Nasypany then briefs Marr on the armaments on board the fighters NEADS has had launched (see 8:46 a.m. September 11, 2001). He adds: “My recommendation, if we have to take anybody out, large aircraft, we use AIM-9s in the face. If need be.” He means that if there is another hijacking, the most effective way to bring the plane down would be to fire a missile into its nose. [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 140-141]
Pilots Do Not Receive Shootdown Authorization - At around 9:35 a.m., according to Spencer, a NEADS weapons controller will ask one of the pilots that launched in response to the first hijacking whether he would be willing to shoot down a hijacked aircraft (see (9:35 a.m.) September 11, 2001). [Spencer, 2008, pp. 153] According to the 9/11 Commission, however, NEADS personnel will only learn that NORAD has been cleared to shoot down threatening aircraft at 10:31 a.m., and even then they will not pass this order along to the fighter pilots (see 10:31 a.m. September 11, 2001).

According to the 9/11 Commission, NEADS is contacted by the FAA’s Boston Center. Colin Scoggins, Boston Center’s military liaison, tells it: “I just had a report that American 11 is still in the air, and it’s on its way towards—heading towards Washington.… That was another—it was evidently another aircraft that hit the tower. That’s the latest report we have.… I’m going to try to confirm an ID for you, but I would assume he’s somewhere over, uh, either New Jersey or somewhere further south.” The NEADS official asks: “He—American 11 is a hijack?… And he’s heading into Washington?” Scoggins answers yes both times and adds, “This could be a third aircraft.” Somehow Boston Center has been told by FAA headquarters that Flight 11 is still airborne, but the 9/11 Commission will say it hasn’t been able to find where this mistaken information came from.
Scoggins Makes Error - Vanity Fair magazine will later add, “In Boston, it is Colin Scoggins who has made the mistaken call.” Scoggins will explain why he believes he made this error: “With American Airlines, we could never confirm if [Flight 11] was down or not, so that left doubt in our minds.” He says he was monitoring a conference call between FAA centers (see 8:28 a.m. September 11, 2001), “when the word came across—from whom or where isn’t clear—that American 11 was thought to be headed for Washington.” However, Boston Center was never tracking Flight 11 on radar after losing sight of it near Manhattan: “The plane’s course, had it continued south past New York in the direction it was flying before it dipped below radar coverage, would have had it headed on a straight course toward DC. This was all controllers were going on.” Scoggins says, “After talking to a supervisor, I made the call and said [American 11] is still in the air.” [Northeast Air Defense Sector, 9/11/2001; 9/11 Commission, 6/17/2004; Vanity Fair, 8/1/2006]
Myers Refers to Mistaken Report - In the hours following the attacks, acting Chairman of the Joint Chiefs of Staff Richard Myers will apparently refer to this erroneous report that Flight 11 is still airborne and heading toward Washington, telling the Associated Press that “prior to the crash into the Pentagon, military officials had been notified that another hijacked plane had been heading from the New York area to Washington.” Myers will say “he assumed that hijacked plane was the one that hit the Pentagon, though he couldn’t be sure.” [Associated Press, 9/11/2001]

Having just received an incorrect report that Flight 11—which has already hit the World Trade Center—is still airborne and heading toward Washington (see 9:21 a.m. September 11, 2001), technicians at NORAD’s Northeast Air Defense Sector (NEADS) try, unsuccessfully, to locate the aircraft on their radar screens. [Spencer, 2008, pp. 137-139] At NEADS, Major James Anderson says the hijackers are “probably not squawking anything anyway,” meaning their plane’s transponder is not broadcasting a signal. He adds, “I mean, obviously these guys are in the cockpit.” Major Kevin Nasypany, the mission crew commander, replies, “These guys are smart.” Another member of staff adds, “Yeah, they knew exactly what they wanted to do.” [Vanity Fair, 8/1/2006] After giving the order to launch the F-16s kept on alert at Langley Air Force Base (see 9:23 a.m. September 11, 2001), Nasypany calls out, “I need more trackers!” He needs his technicians to locate the hijacked plane on radar so that his weapons team can pass on its coordinates to the Langley fighters. But the trackers are unable to find the transponder code for Flight 11 on their radar screens. They begin calling up, one at a time, the tracks on their screens that are in the airspace between New York and Washington, and attach a tag to each after it has been identified. One technician draws a line on a map between New York and Washington, showing the area across which Flight 11 would be traveling. It includes Philadelphia, Atlantic City, and Baltimore. He looks at his radar screen and sees there are hundreds of tracks in that area. [Spencer, 2008, pp. 138-139] Colin Scoggins, the military liaison at the FAA’s Boston Center, who gave NEADS the incorrect report about Flight 11, will later say he’d only heard the plane was still airborne and heading for Washington on a conference call between FAA centers. According to Vanity Fair, air traffic controllers “were never tracking an actual plane on the radar after losing American 11 near Manhattan, but if it had been flying low enough, the plane could have gone undetected.” [Vanity Fair, 8/1/2006]

Major Kevin Nasypany inside NEADSMajor Kevin Nasypany inside NEADS [Source: Mark Schafer/ Vanity Fair]According to the 9/11 Commission, NEADS has just been told that the hijacked Flight 11 is still in the air and heading toward Washington. Major Kevin Nasypany, the mission crew commander, says to NEADS Commander Robert Marr, “Okay, uh, American Airlines is still airborne. Eleven, the first guy, he’s heading towards Washington. Okay? I think we need to scramble Langley right now. And I’m gonna take the fighters from Otis, try to chase this guy down if I can find him.” After receiving approval to do so, Nasypany issues the order. “Okay… scramble Langley,” he says. “Head them towards the Washington area.” The Langley, Virginia, base gets the scramble order at 9:24 a.m. (see 9:24 a.m. September 11, 2001). NEADS keeps its fighters from the Otis base over New York City. In 2004 the 9/11 Commission will state, “this response to a phantom aircraft, American 11, is not recounted in a single public timeline or statement issued by FAA or [Defense Department]. Instead, since 9/11, the scramble of the Langley fighters has been described as a response to the reported hijacking of American 77, or United 93, or some combination of the two.” Yet the “report of American 11 heading south as the cause of the Langley scramble is reflected not just in taped conversations at NEADS, but in taped conversations at FAA centers, on chat logs compiled at NEADS, Continental Region headquarters, and NORAD, and in other records.” [9/11 Commission, 6/17/2004; Vanity Fair, 8/1/2006]

At NORAD’s Northeast Air Defense Sector (NEADS), Master Sergeant Joe McCain, the mission crew commander technician, receives a call from the Continental US NORAD Region (CONR) headquarters at Tyndall Air Force Base in Florida. Major General Larry Arnold and his staff at Tyndall AFB are trying to gather as much information as they can about the ongoing crisis, and want to know the transponder codes for the two fighter jets scrambled from Otis Air National Guard Base in response to the first hijacking (see 8:46 a.m. September 11, 2001), so they can monitor their positions. The CONR officer that makes the call tells McCain to “send [the transponder codes] out on chat,” meaning on NORAD’s own chat system.
NORAD's Computer Chat System - According to author Lynn Spencer, NORAD’s chat system “is similar to the chat rooms on most Internet servers, but classified.” It has three chat rooms that can be used by anyone with proper access. One room is specifically for NEADS, and connects its ID, surveillance, and weapons technicians to its alert fighter squadrons, and is where NEADS gets status reports on fighter units and their aircraft. Another chat room is for CONR, and is where the three CONR sectors—NEADS, the Western Air Defense Sector (WADS), and the Southeast Air Defense Sector (SEADS)—communicate with each other and can “upchannel” information to CONR headquarters. The third room is the Air Warfare Center (AWC), where senior NORAD commanders from the three NORAD regions—CONR, Canada, and Alaska—communicate with each other. NEADS is allowed to monitor this room, but not type into it. When there is a training exercise taking place, as was the case earlier this morning (see (6:30 a.m.) September 11, 2001), one or two additional chat windows will be open specifically for communicating exercise information, to help prevent it being confused with real-world information.
McCain Falling Behind - McCain’s responsibilities at NEADS include monitoring these chat rooms, keeping paper logs of everything that is going on, and taking care of “upchanneling” operational reports to higher headquarters. According to Spencer, “These chat logs help to keep everyone on the same page, but in a situation like the one unfolding they have to be updated almost instantaneously to achieve that end.” But, “The fact that CONR has had to call McCain to get information that by now he would normally have posted alerts him that he is falling behind despite his best efforts.” [Spencer, 2008, pp. 139-140]

According to the 9/11 Commission, the two fighters launched from Otis Air Force Base (see 8:46 a.m. September 11, 2001) arrive over Manhattan at this time, after exiting their holding pattern off the Long Island coast at 9:13 a.m. They then establish a combat air patrol (CAP) over New York. The commission bases this conclusion on its analysis of FAA radar data and interviews with the two Otis pilots. [9/11 Commission, 7/24/2004, pp. 24 and 460; 9/11 Commission, 8/26/2004, pp. 26 and 92] However, numerous eyewitnesses on the ground will report first noticing fighters over New York significantly later, more than an hour after the 9/11 Commission claims according to some accounts (see (9:45 a.m.-10:45 a.m.) September 11, 2001).

A Delta Air Lines Boeing 767, the same kind of aircraft as Delta 1989.A Delta Air Lines Boeing 767, the same kind of aircraft as Delta 1989. [Source: Public domain]The FAA’s Cleveland Center incorrectly concludes that Delta Air Lines Flight 1989 has been hijacked, but accounts will conflict over how it comes to this conclusion. [USA Today, 8/13/2002; Spencer, 2008, pp. 167] Delta 1989, a Boeing 767, is currently in the sector of airspace being monitored by Cleveland Center air traffic controller John Werth. [9/11 Commission, 10/2/2003 pdf file; USA Today, 9/11/2008] It is flying west over Pennsylvania, approaching the Ohio border, and is about 25 miles behind Flight 93. FBI agents suspected Delta 1989 might be the next plane to be hijacked and called the Cleveland Center after the second attack on the World Trade Center, with the warning to watch this flight (see Shortly After 9:03 a.m. September 11, 2001). [USA Today, 8/13/2002] A supervisor at the center told Werth to keep an eye on the flight because, as Werth will later recall, “he was a suspected hijacking because he had taken off from Boston at approximately the same time as” the first two hijacked aircraft, Flights 11 and 175. [9/11 Commission, 10/1/2003 pdf file; USA Today, 9/11/2008]
Controllers Hear Suspicious Communications - When, at 9:28, Werth hears the sound of screaming (subsequently determined to have come from Flight 93) over the radio (see (9:28 a.m.) September 11, 2001), he is unsure which of seven or eight possible aircraft it is coming from. The radio frequency is put on the speaker so other controllers can hear it, and they subsequently make out the words, “get out of here.” [9/11 Commission, 10/1/2003 pdf file; 9/11 Commission, 7/24/2004, pp. 11, 28]
Controllers Think Delta 1989 Is Hijacked - According to USA Today, when Cleveland Center controllers then hear a voice with a heavy accent over the radio, saying “Ladies and gentlemen: Here the captain.… We have a bomb on board” (see (9:32 a.m.) September 11, 2001), they mistakenly think it is coming from Delta 1989, not Flight 93. They suspect the flight has been hijacked, and start informing their chain of command. “Officials at Cleveland Center rush word to Washington: Hijackers have another flight. At the Federal Aviation Administration’s Command Center in Herndon, Virginia, Delta Flight 1989 joins a growing list of suspicious jets.” [USA Today, 8/13/2002; 9/11 Commission, 7/24/2004, pp. 12]
Werth Decides Hijacked Aircraft Is Flight 93 - Werth then calls all of the aircraft in his sector, and Flight 93 is the only one that does not respond. He also sees Flight 93 go into a quick descent and then come back up again. Werth therefore concludes that it is Flight 93, not Delta 1989, that has been hijacked, and instructs his supervisor to “tell Washington” of this. [9/11 Commission, 10/1/2003 pdf file; 9/11 Commission, 10/2/2003 pdf file] However, events in the following minutes will cause Cleveland Center controllers to remain suspicious of Delta 1989 (see (Shortly After 9:44 a.m.) September 11, 2001 and 9:45 a.m. September 11, 2001). [USA Today, 8/13/2002; 9/11 Commission, 10/2/2003 pdf file; Spencer, 2008, pp. 168; USA Today, 9/11/2008]
Book Gives Alternative Account - In a book published in 2008, author Lynn Spencer will give a different explanation for why Cleveland Center becomes suspicious of Delta 1989. According to her account, after hearing a later radio transmission where a hijacker again says “There is a bomb on board” (see (9:39 a.m.) September 11, 2001), Werth begins to hand off his flights to other controllers so he can devote his full attention to Flight 93. “In the distraction of the emergency, the crew of Delta 1989 misses the hand-off to the new frequency. The new sector controller for Delta 1989 calls out to the plane several times and gets no response.” As a result, “News travels fast,” and “Soon, word on the FAA’s open teleconference call is that a fifth aircraft is out of radio contact: Delta 1989… is added to the list of suspect aircraft.” [Spencer, 2008, pp. 167] At 9:39 a.m., even though it is not responsible for handling Delta 1989, the FAA’s Boston Center will call NORAD’s Northeast Air Defense Sector (NEADS) and incorrectly tell it that Delta 1989 is another possible hijack (see 9:39 a.m. September 11, 2001).

The National Miilitary Command Center, inside the Pentagon.The National Miilitary Command Center, inside the Pentagon. [Source: US Department of Defense]The National Military Command Center (NMCC) at the Pentagon finally commences and runs a “significant event conference” in response to the ongoing crisis, 26 minutes after the second plane hit the World Trade Center and officers in the NMCC realized the US was under terrorist attack. [9/11 Commission, 6/17/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 37; American Forces Press Service, 9/7/2006]
NMCC Directors Decided to Establish Conference - After those in the NMCC saw Flight 175 hitting the WTC live on television at 9:03 a.m. (see 9:03 a.m. September 11, 2001), Captain Charles Leidig, the acting deputy director for operations (DDO) in the center throughout the attacks, and Commander Pat Gardner, the assistant DDO, talked about the need to convene a significant event conference so there could be a discussion of what actions were to be taken in response. The DDO and the assistant DDO are the two officers responsible for deciding what type of conference the NMCC should convene, and when it should do so. Because there is no specific procedure for dealing with terrorist attacks, Leidig and Gardner decided a significant event conference would most suit their needs, because it would have the flexibility of allowing more people to be added in as required. They also discussed who would need to be on this conference. [9/11 Commission, 4/29/2004 pdf file] But Major Charles Chambers, who is currently on duty in the NMCC, will give a slightly different account. According to Chambers, Staff Sergeant Val Harrison had a phone in her hand and said NORAD was asking for a significant event conference. Leidig had agreed, and so Harrison started establishing the conference.
Conference Begins with Recap of Situation - According to Chambers, “The computer does a mass dialing to connect to those command centers that are always included” in an NMCC conference call, but Harrison also had to manually call the civilian agencies that were going to be included in the conference, such as the FAA, the FBI, and the Federal Emergency Management Agency (FEMA). [US Department of Defense, 9/2001] The conference then begins at 9:29 a.m. with a brief recap: Two aircraft have hit the WTC, there is a confirmed hijacking of Flight 11, and fighter jets have been scrambled from Otis Air National Guard Base in Massachusetts (see 8:46 a.m. September 11, 2001). The FAA is asked to provide an update, but its line is silent as the agency has not yet been added to the call (see (9:29 a.m.-12:00 p.m.) September 11, 2001). A minute later, Leidig states that it has just been confirmed that Flight 11 is still airborne and is heading toward Washington, DC. (This incorrect information apparently arose minutes earlier during a conference call between FAA centers (see 9:21 a.m. September 11, 2001).) [9/11 Commission, 7/24/2004, pp. 37] NMCC conference calls are moderated by the DDO. [9/11 Commission, 7/21/2003 pdf file] Leidig will tell the 9/11 Commission that they are conducted over “a special phone circuit, and it’s classified to be able to pass information, relay information between very senior leadership all the way over to the White House.” [9/11 Commission, 6/17/2004]
NMCC Struggled to Convene Conference - Some officers currently on duty in the NMCC will later complain about circumstances that delayed the establishing of the significant event conference. Chambers will recall that the conference took “much longer than expected to bring up.” [US Department of Defense, 9/2001] Gardner will tell the 9/11 Commission that the NMCC had been “struggling to build the conference,” which “didn’t get off as quickly as hoped.” [9/11 Commission, 5/5/2004] He will describe his “frustration that it wasn’t brought up more quickly.” [9/11 Commission, 5/12/2004]
Other Conference and Connection Problems Delayed Call - Preparations for the conference were disrupted as a result of the CIA convening a National Operations and Intelligence Watch Officer Network (NOIWON) conference call between government agencies in the Washington area, reportedly at sometime between 9:16 a.m. and 9:25 a.m. (see (Between 9:16 a.m. and 9:25 a.m.) September 11, 2001). According to a 9/11 Commission memorandum, the NMCC had “abandoned its attempt to convene a [significant event conference] so its watch officers could participate in the NOIWON conference.” [Federal Aviation Administration, 9/11/2001; Federal Aviation Administration, 9/11/2001; 9/11 Commission, 7/21/2003 pdf file] Another factor that slowed attempts to convene the significant event conference was a problem with connecting some agencies to it. According to Chambers, “A couple of the civil agencies couldn’t be reached and others kept dropping off moments after connecting.” He will recall, “We finally decided to proceed without those agencies that were having phone problems.” [US Department of Defense, 9/2001] Leidig had announced that the NMCC would have to start without those agencies and add them to the conference later on. [9/11 Commission, 5/12/2004]
Call Ends after Five Minutes - The significant event conference ends after only a few minutes, following a recommendation by NORAD that it be reconvened as an “air threat conference.” It is brought to an end at around 9:34 a.m., and will resume as an air threat conference at 9:37 a.m. (see 9:37 a.m.-9:39 a.m. September 11, 2001).

Thomas Von Essen.Thomas Von Essen. [Source: Publicity photo]The Office of Emergency Management’s Emergency Operations Center (EOC) in World Trade Center Building 7 is evacuated in response to a report that more commercial planes are unaccounted for. [9/11 Commission, 7/24/2004, pp. 305] The EOC, which opened in 1999 (see June 8, 1999), is a state-of-the-art facility on the 23rd floor of WTC 7 that is intended to serve as a meeting place for city leaders in the event of an act of terrorism or other kind of crisis. [CNN, 6/7/1999; City of New York, 2/18/2001] Office of Emergency Management (OEM) officials activated it shortly after Flight 11 crashed into the North Tower of the WTC (see (Shortly After 8:46 a.m.) September 11, 2001). [Bylicki, 6/19/2003; 9/11 Commission, 7/24/2004, pp. 293]
Staffers Discussed Evacuation after the First Crash - Soon after the crash occurred, officials in the EOC “began discussing with OEM staff whether or not they should evacuate the building,” according to a report by Tricia Wachtendorf of the Disaster Research Center at the University of Delaware. [Wachtendorf, 2004, pp. 77] Richard Rotanz, deputy director of the OEM, and some other officials in the EOC conducted a “threat analysis” after the second hijacked plane crashed into the WTC, at 9:03 a.m. (see 9:03 a.m. September 11, 2001). [Urban Hazards Forum, 1/2002]
Staffers Want to Stay in the Operations Center - Personnel are reluctant to leave the EOC because in it they have “a tremendous amount of resources at their fingertips” and they are “best able to handle an emergency of this scale,” Wachtendorf will later write. Furthermore, there is no clear procedure to move to or establish an alternative operations center if it is abandoned. “I couldn’t think of where we would go if we left the EOC because at that time we didn’t have a backup facility,” one official will recall. There is, in fact, “no formalized evacuation plan for the EOC,” according to Wachtendorf. [Wachtendorf, 2004, pp. 77-79]
OEM Deputy Director Orders the Evacuation - However, Richard Bylicki, a police sergeant assigned to the OEM, was told during a call with the FAA that at least one other plane, in addition to the two that hit the Twin Towers, is unaccounted for and possibly heading for New York (see (9:30 a.m.) September 11, 2001), and he passed this information on to Rotanz. [Bylicki, 6/19/2003] Rotanz was given the same warning by a Secret Service agent who works in WTC 7. [Urban Hazards Forum, 1/2002; 9/11 Commission, 7/24/2004, pp. 305] Based on this information, he “surmised that [WTC 7] was potentially the next target,” Bylicki will recall. He consequently now orders all OEM employees to leave the building. [Bylicki, 6/19/2003; 9/11 Commission, 4/7/2004] A Secret Service agent, presumably the one who told Rotanz about the additional unaccounted-for planes, also reportedly advises EOC personnel to evacuate. He says, “There’s a reported third plane headed toward the East Coast and we’re warning everybody to vacate the building,” Fire Department Captain Abdo Nahmod will recall. [Journal of Emergency Medical Services, 9/2011, pp. 42 pdf file]
Some Liaisons Have Come to the Operations Center - Various city agencies were contacted after the EOC was activated and instructed to send their designated representatives to the center. None of these representatives have arrived by the time the EOC is evacuated, according to the 9/11 Commission Report. [9/11 Commission, 5/18/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 293, 305] However, contradicting this claim, a number of emergency responders will recall arriving at the EOC before it is evacuated, to serve as representatives for their agencies. [City of New York, 10/11/2001; City of New York, 10/25/2001; City of New York, 12/4/2001; Journal of Emergency Medical Services, 9/2011, pp. 42 pdf file]
Staffers Are Initially Slow to Leave - Personnel reportedly do not initially respond to the evacuation order with a sense of urgency. They “calmly collected personal belongings and began removing OEM records,” a report by the Mineta Transportation Institute will state. But they are subsequently “urged to abandon everything and leave the building quickly.” [Jenkins and Edwards-Winslow, 9/2003, pp. 16 pdf file] After evacuating from the EOC, they assemble in the lobby of WTC 7 and await further instructions over radio. [Bylicki, 6/19/2003] Most of them think they are only temporarily abandoning their facility and expect to return to it later in the day. They do not anticipate WTC 7 being affected by fires (see 4:10 p.m. September 11, 2001) and then collapsing late this afternoon (see (5:20 p.m.) September 11, 2001). [Wachtendorf, 2004, pp. 84]
Fire Commissioner Will Be Surprised That the Center Is Evacuated - Fire Commissioner Thomas Von Essen will be surprised when he finds that the EOC has been evacuated, since the center was designed for dealing with a crisis like the one currently taking place. “I thought that was where we should all be because that’s what [it] was built for,” he will comment. He will arrive at WTC 7 looking for Mayor Rudolph Giuliani shortly before 9:59 a.m., when the South Tower collapses (see 9:59 a.m. September 11, 2001). When he learns that the EOC has been evacuated, he will think: “How ridiculous. We’ve got a 13-million-dollar command center and we can’t even use it.” He will say in frustration: “How can we be evacuating OEM? We really need it now.” [Essen, 2002, pp. 26; Fink and Mathias, 2002, pp. 230]
Time of the Evacuation Is Unclear - It is unclear exactly when the EOC is evacuated. The order to evacuate is issued at “approximately 9:30” a.m., according to the 9/11 Commission Report. [9/11 Commission, 7/24/2004, pp. 305] But, according to a report by the National Institute of Standards of Technology, the evacuation occurs slightly later than this, at “approximately 9:44 a.m.” [National Institute of Standards and Technology, 9/2005, pp. 109] Other accounts will suggest it may even have taken place before the second attack on the WTC occurred (see (Soon After 8:46 a.m.-9:35 a.m.) September 11, 2001 and (Shortly Before 9:03 a.m.) September 11, 2001). [Barrett and Collins, 2006, pp. 34; Dylan Avery, 2007] Many people in the rest of WTC 7 left the building earlier on, around the time of the second attack (see (9:03 a.m.) September 11, 2001).

Two unidentified military aircraft fly in the vicinity of the Pentagon at an altitude of over 20,000 feet, and are in the area during the minutes before the Pentagon is hit. [Federal Aviation Administration, 9/20/2001 pdf file; 9/11 Commission, 7/28/2003 pdf file] Between at least 9:31 a.m. and 9:40 a.m., the two aircraft communicate with the air traffic control tower at Washington’s Reagan National Airport, which is less than a mile from the Pentagon. [Federal Aviation Administration, 9/20/2001 pdf file; St. Petersburg Times, 10/3/2001] Radar data will show that they fly “in trail” (in single file, with one aircraft directly behind the other) at 21,000 feet, and are overhead during the last few minutes that Flight 77 is airborne, before it hits the Pentagon at 9:37 a.m. (see 9:37 a.m. September 11, 2001). [9/11 Commission, 7/28/2003 pdf file]
Launched from Delaware Base - The identities of the two aircraft are unclear. They have the call signs “Bobcat 14” and “Bobcat 17.” [Federal Aviation Administration, 9/20/2001 pdf file] A 9/11 Commission memorandum will state that “flight strips and other information indicate that Bobcat 14 and Bobcat 17 originated out of Dover Air Force Base in Delaware.… It is possible, but not confirmed, that they were Air Force corporate passenger jets.”
Airport Managers Do Not Recall Planes - Two key officials will later be unable to specifically recall the aircraft when questioned by the 9/11 Commission. Bob Lazar, the acting operations manager at Reagan National Airport, will say he “did not remember any aircraft with the call sign ‘Bobcat’ that hung out over the National airspace” on this day. However, as well as two of the fighter jets that are inbound from Langley Air Force Base (see (9:25 a.m.-9:30 a.m.) September 11, 2001), he will recall two aircraft “coming from the north, but he did not think that they entered National’s airspace.” Donny Simons, the airport manager at Baltimore-Washington International Airport in Linthicum, Maryland, will stress “that he did not remember the Bobcats specifically,” but he speculates that controllers at his airport “were working the two ‘Bobcats’ and needed vectors from National controllers.” [9/11 Commission, 7/28/2003 pdf file]

At the FAA’s Cleveland Center, an air traffic controller hears a transmission, presumably made by Flight 93 hijacker-pilot Ziad Jarrah, stating: “Ladies and gentlemen: Here the captain, please sit down, keep remaining sitting. We have a bomb on board. So, sit.” [9/11 Commission, 7/24/2004, pp. 12; 9/11 Commission, 8/26/2004, pp. 39] As the 9/11 Commission later notes, “Like [Mohamed] Atta on Flight 11, Jarrah apparently did not know how to operate the communication radios; thus his attempts to communicate with the passengers were broadcast on the [air traffic control] channel.” [9/11 Commission, 8/26/2004, pp. 98] While this communication is assumed to have come from Flight 93, an early FAA report states that it came “from an unknown origin.” [Federal Aviation Administration, 9/17/2001 pdf file] According to Newsweek, just prior to the communication, Cleveland Center controllers heard the sound of screaming from the flight. [Newsweek, 9/22/2001] The 9/11 Commission states that, around the time of the transmission, the plane’s cockpit voice recording indicates “that a woman, most likely a flight attendant, was being held captive in the cockpit. She struggled with one of the hijackers who killed or otherwise silenced her.” [9/11 Commission, 7/24/2004, pp. 12; 9/11 Commission, 8/26/2004, pp. 39] Though the Cleveland air traffic controller understands the hijacker’s communication, he responds to it: “Calling Cleveland Center, you’re unreadable. Say again, slowly.” He also notifies his supervisor who passes the information up the chain of command, and the FAA’s Command Center is subsequently informed, “United 93 may have a bomb on board.” At 9:34 the Command Center will relay this information to FAA headquarters (see 9:34 a.m. September 11, 2001).

According to the 9/11 Commission, NEADS contacts Washington flight control to ask about Flight 11. A manager there happens to mention, “We’re looking—we also lost American 77.” The commission claims, “This was the first notice to the military that American 77 was missing, and it had come by chance.… No one at FAA Command Center or headquarters ever asked for military assistance with American 77.” [9/11 Commission, 6/17/2004] Yet, 38 minutes earlier, flight controllers determined Flight 77 was off course, out of radio contact, and had no transponder signal (see 8:56 a.m. September 11, 2001). They’d warned American Airlines headquarters within minutes. By some accounts, this is the first time NORAD is told about Flight 77, but other accounts have them warned around 9:25 a.m.

In answer to a question from a weapons controller at NORAD’s Northeast Air Defense Sector (NEADS), one of the pilots that took off in response to Flight 11 confirms that he would be willing to shoot down a hijacked aircraft. [Spencer, 2008, pp. 153] Major Kevin Nasypany, the NEADS mission crew commander, has already checked that his section heads and weapons technicians are prepared to order the shooting down of a civilian aircraft (see (9:19 a.m.) September 11, 2001). At 9:32, after NEADS received a report of a hijacked plane approaching Washington (see 9:21 a.m. September 11, 2001), Major James Anderson asked Nasypany what would happen if they located that aircraft, saying, “Are we gonna shoot him down if they got passengers on board?” [Vanity Fair, 8/1/2006]
Duffy Says He Would Shoot down a Plane - Nasypany wants to be sure that his pilots are willing to follow a shootdown order, should one be issued. He therefore directs his weapons controller who is dealing with the fighter jets launched from Otis Air National Guard Base (see 8:46 a.m. September 11, 2001) to check this. The weapons controller radios Otis pilot Lt. Col. Timothy Duffy and tells him, “If we get another hijack track, you’re going to be ordered to shoot it down.” He then asks, “Do you have a problem with that?” Somewhat startled by the question, Duffy replies, “No—no problem with that.” He reportedly thinks to himself, “If I have a problem with that order, I am in the wrong seat.” According to author Lynn Spencer, Duffy is “doing what he’s been trained to do.… [I]f he gets a legal, lawful order to take out an airliner, then that’s what he’s going to do. He knows every other fighter pilot would do the same.” Duffy and the other Otis pilot that launched with him, Major Daniel Nash, are “confident no plane will get past them: they’ll do what it takes, and follow any order, to protect New York.” [Spencer, 2008, pp. 153] Duffy will later tell the Boston Globe: “[P]eople have said, ‘Would you have done it [i.e. shot down a hostile airliner]?’ Absolutely, that’s my job.” [Boston Globe, 9/11/2005]
No Shootdown Order Issued - However, according to the 9/11 Commission, NEADS personnel will only learn that NORAD has been cleared to shoot down threatening aircraft at 10:31 a.m. (see 10:31 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 42] And, according to most accounts, the two Otis pilots never receive an order from the military to shoot down an airliner (see (After 9:35 a.m.) September 11, 2001). [Cape Cod Times, 8/21/2002; Boston Globe, 9/11/2005] Duffy and Nash will also be contacted by a civilian air traffic controller regarding the possibility of shooting down a hijacked aircraft (see (9:59 a.m.) September 11, 2001).

A KC-135 Stratotanker.A KC-135 Stratotanker. [Source: Boeing]The two F-15 fighter jets launched from Otis Air National Guard Base in response to Flight 11 (see 8:46 a.m. September 11, 2001) are finally able to refuel, after they request to rendezvous with a tanker plane that was scheduled to refuel Otis fighters out on training missions this morning. [Aviation Week and Space Technology, 6/3/2002; Spencer, 2008, pp. 153]
Fighters Low on Fuel - By around 9:35 a.m., according to author Lynn Spencer, the two Otis fighters are running increasingly low on fuel and need to find a fuel tanker right away. For about the last 25 minutes, technicians at NORAD’s Northeast Air Defense Sector (NEADS) have been searching for a tanker (see (9:09 a.m.) September 11, 2001). [Spencer, 2008, pp. 112 and 152-153] A member of staff at NEADS in fact talked over the radio with a KC-135 tanker from Bangor, Maine, at around 9:05 a.m., and the plane’s crew agreed to provide support to the Otis fighters launched in response to Flight 11 (see 9:04 a.m.-9:06 a.m. September 11, 2001). [North American Aerospace Defense Command, 9/11/2001; North American Aerospace Defense Command, 9/11/2001] However, the pilots of these fighters have apparently not heard back from NEADS about whether it has been able to find a tanker for them. Now one of the pilots, Major Daniel Nash, has come up with a solution. Prior to being put on alert duty, he had been acting as the scheduling officer at Otis Air Base, and he therefore knows that a training mission a number of Otis fighters were scheduled to fly today called for refueling (see (9:00 a.m.-9:24 a.m.) September 11, 2001). Consequently he knows about the KC-135 tanker plane from Bangor that NEADS communicated with earlier on, which had been scheduled to support those fighters during their training. [102nd Fighter Wing, 2001; Spencer, 2008, pp. 152-153]
Tanker Heading toward Training Airspace - The tanker plane, which has the call sign “Maine 85,” is one of the eight KC-135s that are attached to the 101st Air Refueling Wing, based at Bangor International Airport. Its pilots are Lieutenant Colonel Adam Jenkins and Lieutenant Colonel Andy Marshall. [Portland Press Herald, 9/13/2001; Bangor Daily News, 9/9/2011] It had been scheduled to rendezvous with the Otis fighters on their training mission about 20 minutes from now in “Whiskey 105,” the military training airspace just south of Long Island, where Nash and his fellow Otis pilot Timothy Duffy had earlier been flying in a “holding pattern” (see 9:09 a.m.-9:13 a.m. September 11, 2001). The KC-135 should be on its way there now. Nash calls Duffy and tells him, “[W]e have a tanker scheduled for the training missions this morning off the coast in 105.” Duffy calls NEADS and requests that the KC-135 orbit at 20,000 feet above New York’s JFK International Airport. NEADS then coordinates with the 101st Air Refueling Wing to borrow the tanker. [Aviation Week and Space Technology, 6/3/2002; Spencer, 2008, pp. 153]
Tanker Directed toward New York - The KC-135 is instructed to fly toward Manhattan. Jenkins will later recall, “We were told to start heading west to the city.” The voice over his radio tells him, “We’ll give you details along the way.” [Bangor Daily News, 9/9/2011] Soon, the KC-135 is flying an orbit over JFK Airport and the two Otis fighters then take turns refueling. [Grant, 2004, pp. 21; Grant and Thompson, 10/6/2006, pp. 4 pdf file; Spencer, 2008, pp. 153] According to the 9/11 Commission Report, the two Otis fighters arrived over Manhattan at 9:25 a.m. (see 9:25 a.m. September 11, 2001), but accounts of most witnesses on the ground indicate they do not arrive there until after 10:00 a.m. (see (9:45 a.m.-10:45 a.m.) September 11, 2001).

The Pentagon explodes. [Source: Donley/ Sipa]Flight 77 crashes into the Pentagon. All 64 people on the plane are killed. A hundred-and-twenty-four people working in the building are killed, and a further victim will die in hospital several days later. Hijackers Hani Hanjour, Khalid Almihdhar, Majed Moqed, Nawaf Alhazmi, and Salem Alhazmi presumably are killed instantly. (Typically, they are not included in the death counts.) [CNN, 9/17/2001; North American Aerospace Defense Command, 9/18/2001; Guardian, 10/17/2001; Washington Post, 11/21/2001; USA Today, 8/12/2002; Associated Press, 8/21/2002; MSNBC, 9/3/2002; ABC News, 9/11/2002; CBS, 9/11/2002] Flight 77 hits the first floor of the Pentagon’s west wall. The impact and the resulting explosion heavily damage the building’s three outer rings. The path of destruction cuts through Army accounting offices on the outer E Ring, the Navy Command Center on the D Ring, and the Defense Intelligence Agency’s comptroller’s office on the C Ring. [Vogel, 2007, pp. 431 and 449] Flight 77 strikes the only side of the Pentagon that had recently been renovated—it was “within days of being totally [renovated].” [US Department of Defense, 9/15/2001] “It was the only area of the Pentagon with a sprinkler system, and it had been reconstructed with a web of steel columns and bars to withstand bomb blasts. The area struck by the plane also had blast-resistant windows—two inches thick and 2,500 pounds each—that stayed intact during the crash and fire. While perhaps, 4,500 people normally would have been working in the hardest-hit areas, because of the renovation work only about 800 were there.” More than 25,000 people work at the Pentagon. [Los Angeles Times, 9/16/2001] Furthermore, the plane hits an area that has no basement. As journalist Steve Vogel later points out, “If there had been one under the first floor, its occupants could easily have been trapped by fire and killed when the upper floors collapsed.” [Vogel, 2007, pp. 450]

Secret Service executives implement an “emergency call-up” of all their agency’s personnel at some time after 9:37 a.m., when the Pentagon was hit, according to US News and World Report. The reason why the Secret Service did not call up all its personnel earlier on is unstated, as is the reason it decides to do so now. [US News and World Report, 12/1/2002] The Secret Service is responsible for protecting the nation’s “most visible targets,” including the president, the vice president, and the White House complex. [US Department of the Treasury, 5/8/2001; Office of Management and Budget, 7/2001, pp. 82 pdf file] Brian Stafford, the agency’s director, realized the US was under attack after the second plane hit the World Trade Center at 9:03 a.m. (see 9:03 a.m. September 11, 2001), and then activated the Director’s Crisis Center at Secret Service headquarters to manage the agency’s response (see (Shortly After 9:03 a.m.) September 11, 2001). [United States Secret Service, 10/1/2001; Peter Schnall, 10/24/2004] And since around 9:18 a.m., a meeting has been taking place in the office of Carl Truscott, the special agent in charge of the presidential protective division, during which Truscott and three other senior Secret Service agents have discussed security enhancements at the White House (see (9:18 a.m.) September 11, 2001).

The Flight 93 hijackers (probably inadvertently) transmit over the radio: “Hi, this is the captain. We’d like you all to remain seated. There is a bomb on board. And we are going to turn back to the airport. And they had our demands, so please remain quiet.” [Boston Globe, 11/23/2001; Longman, 2002, pp. 209; MSNBC, 9/3/2002; 9/11 Commission, 6/17/2004] The controller responds, “United 93, understand you have a bomb on board. Go ahead,” but there is no response. There was a very similar “bomb on board” warning from the same flight at 9:32 a.m. (see (9:32 a.m.) September 11, 2001). The 9/11 Commission indicates that these are separate incidents. [9/11 Commission, 6/17/2004] Cleveland flight control apparently continues to wait for FAA superiors to notify NORAD. Earlier in the morning, Boston flight control directly contacted NORAD (see (8:37 a.m.) September 11, 2001) and local air force bases when they determined Flight 11 was hijacked.

The FAA’s Command Center in Herndon, Virginia, provides updates to FAA headquarters in Washington, DC, about the problems with Flight 93. At 9:41 a.m., John White, a manager at the Command Center, is talking to Doug Davis, the special assistant for technical operations in air traffic services at FAA headquarters. White says that Flight 93 has reversed course from its intended flight path (see (9:36 a.m.) September 11, 2001), its transponder signal has been lost (see (9:40 a.m.) September 11, 2001), and it is now descending and heading east. From 9:42 a.m., one of the Command Center managers (exactly who is unstated) gives the headquarters several updates on Flight 93’s progress and location. At 9:46 a.m., White tells Jeff Griffith, the FAA’s deputy director of air traffic, that Flight 93 is “29 minutes out of Washington, DC, and tracking toward us.” Two minutes later, in another conversation with Griffith, White confirms that Flight 93 has reversed course and is heading toward Washington.

The Delta Air Lines operations control center in Atlanta, Georgia.The Delta Air Lines operations control center in Atlanta, Georgia. [Source: Public domain]Delta Air Lines instructs one of its aircraft, Flight 1989, to land at Cleveland Hopkins Airport, but the FAA’s Cleveland Center, which is handling the aircraft, is not notified of this. [USA Today, 8/13/2002; Associated Press, 8/15/2002]
Pilots Instructed to Land - The pilots of Delta 1989 receive an ACARS text message from their airline’s dispatch office in Atlanta, Georgia, instructing them to “Land immediately in Cleveland.” [Spencer, 2008, pp. 167] According to USA Today, “Since early reports that a bomb, then hijackers, might be aboard” Delta 1989, Delta Air Lines’ headquarters in Atlanta has been tracking the flight, and receiving reports on it every five minutes. [USA Today, 8/13/2002] The plane’s pilot, Captain Paul Werner, quickly types a response to the message, “ok.” But, a couple of minutes later, he receives another ACARS message from the airline. It says: “Confirm landing in Cleveland. Use correct phraseology.” Werner and First Officer David Dunlap are puzzled. According to author Lynn Spencer: “There’s such a thing as correct phraseology on the radio, but there is no such thing when typing back and forth with dispatch on ACARS. Those messages are usually casual.” Werner carefully types a response: “Roger. Affirmative. Delta 1989 is diverting to Cleveland.” He calls the Cleveland Center at 9:44 a.m. and requests a diversion to Cleveland Airport. [Spencer, 2008, pp. 167-168; USA Today, 9/11/2008]
Cleveland Center Not Informed - About 15 minutes earlier, Cleveland Center heard the sounds from Flight 93 as it was being hijacked, but initially thought these came from Delta 1989, and mistakenly believed the Delta flight was being taken over (see (9:28 a.m.-9:33 a.m.) September 11, 2001). [USA Today, 8/13/2002] But the Delta pilots’ normal responses to radio transmissions soon led air traffic controller John Werth, who is handling Delta 1989, to conclude that this aircraft was fine. [USA Today, 9/11/2008] However, controllers at the Cleveland Center are unaware that Delta Air Lines has instructed Flight 1989 to land, and so Werner’s request for a change of course will make them suspicious of it again (see (Shortly After 9:44 a.m.) September 11, 2001).

John Keane.John Keane. [Source: US Army]The Army’s Crisis Action Team (CAT) at the Pentagon is “formally stood up” and its members respond to the terrorist attacks. [Rossow, 2003, pp. 66; Goldberg et al., 2007, pp. 135; St. Louis Jewish Light, 9/8/2011] Lieutenant Colonel Kevin Stramara activated the CAT after the second hijacked aircraft crashed into the World Trade Center, at 9:03 a.m., on the orders of Major General Peter Chiarelli, the Army’s director of operations, readiness, and mobilization (see (Shortly After 9:03 a.m.) September 11, 2001). [US Army Center of Military History, 2/5/2002; Lofgren, 2011, pp. 96-97] Chiarelli’s intention was, he said, “to respond to the contingency in New York if requested by state and local officials.” [Goldberg et al., 2007, pp. 134] The CAT is now “formally stood up,” according to author Robert Rossow, although exactly what this means is unstated.
Senior Officials Come to Operations Center - When the CAT is activated, its members assemble in the Army Operations Center (AOC) in the basement of the Pentagon. [Rossow, 2003, pp. 64, 66] Numerous senior officials now start arriving in the AOC. These include General John Keane, vice chief of staff of the Army; Brigadier General Clyde Vaughn, deputy director of operations, readiness, and mobilization; Major General Philip Kensinger, assistant deputy chief of staff for operations and plans; and Thomas White, the secretary of the Army. More senior officers come to the AOC than would usually be the case in a crisis, according to Chiarelli, “because a large portion of the Army section of the building had been destroyed” in the attack on the Pentagon. “People had been forced out of their space,” he will later say, and “were looking for some place to go.” [US Army Center of Military History, 2/5/2002; US Army Center of Military History, 2/12/2002; Goldberg et al., 2007, pp. 135; Lofgren, 2011, pp. 98-101; Fox News, 9/12/2011]
Operations Center Personnel Unaware that a Plane Hit the Pentagon - Chiarelli arrived at the AOC shortly before the Pentagon was hit (see (Shortly Before 9:37 a.m.) September 11, 2001) and, he will recall, heard a “muffled noise” when the attack occurred, at 9:37 a.m. (see 9:37 a.m. September 11, 2001). [US Army Center of Military History, 2/5/2002; Lofgren, 2011, pp. 98-99] Colonel Henry Huntley, who also arrived at the AOC around the time of the Pentagon attack, will recall, “Alarms started going off and there was an announcement that an explosion had gone off in the building.” [Daily American, 7/8/2008] However, those in the AOC are apparently initially unaware that a plane has hit their building. Vaughn, who witnessed the attack from the road outside the Pentagon, calls Major George Sterling, the AOC commandant, and says to him, “You know that you’ve been hit by an airplane?” Sterling responds, “Is that what happened?” Vaughn will comment that “many people… didn’t find out for some time” that the Pentagon had been hit by an airplane. [US Army Center of Military History, 2/12/2002; Rossow, 2003, pp. 15-16; Lofgren, 2011, pp. 3-4]
Support Agency Commander Unaware that the US Is under Attack - Colonel Bruce Bachus, commander of the Command and Control Support Agency, who is responsible for keeping the AOC operating, arrived at the Pentagon around the time the attack there occurred and yet he is unaware of the crisis taking place in the US when he gets to the AOC. In the AOC, Dick Mansfield, deputy director of the Command and Control Support Agency, says to him: “We’ve been hit! The CAT has been stood up!” But Bachus appears to be puzzled. Mansfield therefore asks him, “Sir, do you know what’s going on?” Bachus says no and that he had not been listening to the radio—like he usually does—while he drove to work. He says he heard a loud sound while he was in the Pentagon’s A-E Drive, and saw people shouting and running down the corridors, but he’d had no idea what was going on. Mansfield therefore has to quickly brief him on the catastrophic events of the past hour. [Rossow, 2003, pp. 9, 68]
Crisis Team Assesses How Many Army Staffers Are Missing - The “first big task” for the CAT, according to Vaughn, is “to get a count on how many people were missing on the Army staff.” Chiarelli instructs Vaughn to focus on this assignment. Vaughn then announces on the CAT floor that he wants each section “to start that process of figuring out who was missing and who was not.” “For a long time, our number one priority was locating and identifying and taking care of… our soldiers and civilians,” Vaughn will say. [US Army Center of Military History, 2/12/2002] Lieutenant Colonel Richard Kotch, who is working in the AOC this morning, will recall that those in the operations center also “assured continuity of operations after the impact [i.e. the attack on the Pentagon].” [St. Louis Jewish Light, 9/8/2011]
Intelligence Officers Give Inaccurate Reports of Hijackings - Meanwhile, after he arrives at the AOC, Chiarelli receives reports from his intelligence officers informing him, inaccurately, about additional hijacked aircraft. He is told there are “a minimum of four aircraft that were hijacked and a possibility, at one time, [of] as high as seven.” [US Army Center of Military History, 2/5/2002; Lofgren, 2011, pp. 99]
Operations Center Has Sophisticated Equipment - The CAT, according to Soldiers magazine, “consists of a dedicated ‘hot’ desk with classified and unclassified computers, and secure telephones for 24 separate Army staff sections.” [Soldiers, 9/2004] The AOC, where its members assemble, is equipped with state-of-the-art communications equipment and has television sets for monitoring news coverage. [Washington Post, 8/25/1995] A glassed-in balcony overlooks the main floor and four giant screens are on the wall above the computer workstations. [US Army Center of Military History, 2/5/2002; Lofgren, 2011, pp. 99-100]
Watch Team Regularly Communicates with Government Agencies - AOC personnel usually work around the clock to keep senior Army leaders aware of issues and events around the world. A watch team monitors the world constantly and is ready to sound the alarm if a crisis erupts somewhere. The watch team also “directs hundreds of communications daily to the FBI, the State Department, the White House command center, local law enforcement agencies, and others,” according to Soldiers magazine. The AOC is equipped with an “emergency action console,” which is a switchboard with a sophisticated communications system that allows watch team members to contact, at the touch of a button, the White House, the secretary of defense’s office, and Army commands around the world. [Washington Post, 8/25/1995; Soldiers, 9/2004] The CAT will become “a focal point for all Pentagon activities” in response to the terrorist attacks, according to Kotch. [St. Louis Jewish Light, 9/8/2011] It will continue working around the clock in the aftermath of the attacks. [US Army Center of Military History, 2/5/2002]

Mess Is a 'Tiny, Unsecure' Facility - The White House mess is an exclusive dining facility run by the US Navy, located in the basement of the West Wing, just under the Oval Office. [All Hands, 12/1/2001; National Review, 10/8/2013] Bridgeland will recall thinking “how odd it was” for White House staffers to all be evacuated to this “tiny, unsecure” facility. [Bridgeland, 2012, pp. 4] People in the mess are watching television or just waiting. [White House, 8/29/2002] Kuo will describe: “All the tables had been tossed onto their sides to make room for as many people as possible. Fifty people stood there, shocked, quiet, confused.” [Kuo, 2006, pp. 185]
People Ordered to the Mess after the Pentagon Attack - The exact time at which staffers are ordered to go to the mess is unclear. Matalin will recall being told to go there “moments” after she sees Cheney being evacuated from his office, which would be some time shortly after 9:36 a.m. (see (9:36 a.m.) September 11, 2001). [National Review, 9/8/2011; Carville and Matalin, 2014, pp. 137-138] Bridgeland and Kuo will recall being ordered to go there shortly after they learn the Pentagon has been hit, which would be some time after 9:37 a.m., when the Pentagon attack occurred (see 9:37 a.m. September 11, 2001). [Kuo, 2006, pp. 184-185; Bridgeland, 2012, pp. 3]

[Associated Press, 2001 pdf file; Washington Post, 1/27/2002] Bridgeland will describe: “[A]n alarmed police officer came into the White House mess and instructed us to leave. Another officer outside was receiving the latest communications by wire (apparently alerted that United Airlines Flight 93 was headed toward the White House or US Capitol building) and commanded us, ‘Take off your shoes and run as fast as you can.’” [Bridgeland, 2012, pp. 4] Matalin will recall that the order she hears, which is delivered “in a weirdly calm manner,” is: “Run for your lives.

Other witnesses say the fighters arrive soon after this collapse:
bullet Deputy Fire Chief Robert Browne, police officer Peter Moog, and emergency medical technicians Richard Zarrillo and Jason Katz notice fighters overhead immediately after, or fairly soon after, the second tower’s collapse. [City of New York, 10/24/2001; City of New York, 10/25/2001; City of New York, 12/20/2001; Fink and Mathias, 2002, pp. 79-80]
bullet Mayor Rudolph Giuliani, Police Commissioner Bernard Kerik, and Office of Emergency Management Director Richard Sheirer are heading north together after leaving their temporary command post on Barclay Street (see (9:50 a.m.-10:10 a.m.) September 11, 2001). In some accounts, all three of them recollect hearing the first military jets overhead soon after the second tower’s collapse. [Kerik, 2001, pp. 339-340; Giuliani, 2002, pp. 14; 9/11 Commission, 5/18/2004 pdf file] However, according to another account, Giuliani hears the first jet slightly earlier, at around 10:20 a.m. And, in his private testimony before the 9/11 Commission, Kerik claims to have heard a fighter jet coming when he was heading to the temporary command post on Barclay Street, i.e. shortly before 9:50 a.m. [Barrett and Collins, 2006, pp. 348-349]
A few witnesses claim the fighters arrive earlier on, before the first collapse at 9:59 a.m.:

The fighter(s) are presumably the F-15s launched from Otis Air Force Base at 8:46 a.m. (see 8:46 a.m. September 11, 2001). However, the 9/11 Commission will claim that these arrived over Manhattan at 9:25 a.m. (see 9:25 a.m. September 11, 2001), which is significantly earlier than most of the witnesses on the ground recall.

Engine Company 16.Engine Company 16. [Source: District of Columbia Fire and Emergency Medical Services Department]The District of Columbia Fire Department (DCFD) sends engines to the White House after the Secret Service incorrectly reports that a plane has crashed into the presidential residence and the building is on fire. As well as reporting the supposed plane crash and fire, the Secret Service says the White House, or at least part of it (the specific details are unclear), has collapsed. In response to the report, the fire communications center dispatches a “box alarm” from Engine Company 16, the station that serves the White House. [Washington City Paper, 9/21/2001; Journal of Emergency Medical Services, 4/2002 pdf file; Firehouse Magazine, 10/31/2002] A box alarm consists of four engines, two trucks, a rescue company, and a battalion chief. [Journal of Emergency Medical Services, 4/2002 pdf file] Since the alleged incident is at the White House—the home of the US president—the response is increased by sending an additional battalion chief and the deputy fire chief, Rogers Massey, to deal with it. And because a building collapse has been reported, the DCFD’s cave-in task force, which comprises Rescue 3, Battalion Chief 3, Engine 15, and the hazmat (hazardous materials) task force, is also sent. However, when the crews arrive at the White House, they are promptly told to leave. A uniformed Secret Service officer waves them away and says: “Get the f_ck outta here! There’s a plane coming in!” Lieutenant Jeff Wright, one of the firefighters involved in the response, will later recall the turn of events, saying: “It was mass confusion. We go down to the White House and no one knows what’s going on. We could see smoke coming from Virginia [where the Pentagon is located].” The report of the incident at the White House is investigated and determined to be unfounded. However, after he receives intelligence reports from the FBI, Special Operations Battalion Chief Michael Sellitto decides he will keep his units near the White House in case attacks should subsequently occur there or at the Capitol building.
