In the fall of 1960, 1961, and 1962, the United States conducts three large-scale air defense exercises called Sky Shield that require a complete ban on commercial and private aviation for about 12 hours. During a period of extreme tensions with the Soviet Union and widespread fear of a nuclear attack by bombers or intercontinental missiles, the Sky Shield exercises test the reliability of North America’s elaborate network of radar stations in Alaska, Northern Canada, and Greenland, as well as along the Atlantic and Pacific coasts. Each exercise involves an attack by a fleet of “Soviet” bombers (actually US, Canadian, and British planes) from the North Pole or from the coasts, followed by the mobilization of hundreds of fighter jets trying to intercept and shoot down the intruders. Sky Shield will be recalled after 9/11 in part because it will be the first time in 40 years that the skies are completely cleared. The third Sky Shield, in 1962, involves the systematic grounding of hundreds of civilian jets as rapidly as possible to test the FAA’s ability to clear the skies in case of attack. This procedure, called SCATANA, will be implemented again on 9/11 on NORAD’s order (see (11:00 a.m.) September 11, 2001).

Personnel at United Airlines’ headquarters, near Chicago, are subjected to a surprise training exercise in which they are led to believe that one of their planes has crashed, and their experience with this exercise allegedly means they will be better able to respond to the 9/11 attacks. [USA Today, 8/12/2002; 9/11 Commission, 11/20/2003 pdf file; Studdert, 5/26/2015 pdf file; Dubuque Telegraph Herald, 11/12/2015]
Manager Is Concerned that the Airline Is Unprepared for an Accident - Andy Studdert, United Airlines’ chief operating officer, has been concerned that, since it hasn’t suffered a real accident in over 15 years, United Airlines is unprepared to respond properly should one occur now. “I was worried we’d become cocky,” he will later comment. “We thought it couldn’t happen to us.” Around March this year, therefore, he told the airline’s other managers, “One of these days, I’m gonna come in here and I’m gonna do a no-notice drill.” [Center for Values-Driven Leadership, 3/15/2012; Center for Values-Driven Leadership, 4/26/2012] A “no-notice” drill is an exercise that is conducted without its participants being given any formal advance notice of when it will occur. [US Department of Justice, 5/21/2000; Inglesby, Grossman, and O'Toole, 2/1/2001; Oak Ridge Institute for Science and Education, 10/15/2011]
Pilot Is Told to Pretend His Plane Is Experiencing an Emergency - Today, Studdert holds this no-notice exercise. Only a few people know about it in advance. Studdert tells a United Airlines employee who he will refer to as his “safety guy” to contact the pilot of a flight to Australia and give them some instructions. The pilot is therefore told he needs to call in during his flight and report an emergency. He should say there is an “uncontained number three engine failure, rapid descent, decompression,” but stop talking halfway through the word “decompression” and then go silent. He should also turn off the plane’s transponder. [Center for Values-Driven Leadership, 3/15/2012; Dubuque Telegraph Herald, 11/12/2015] (A transponder is a device that sends an aircraft’s identifying information, speed, and altitude to air traffic controllers’ radar screens. [Washington Post, 9/16/2001] )
Airline Personnel Think One of Their Planes Has Crashed - The simulated emergency takes places this afternoon. At around 2 o’clock, Studdert is interrupted by his secretary, Maryann Irving, who rushes into his office and tells him a Boeing 747 has lost contact while flying over the Pacific Ocean. In response, he runs to the airline’s operations center. [Wall Street Journal, 10/15/2001; Center for Values-Driven Leadership, 3/15/2012] Airline employees believe the apparently troubled aircraft has crashed. Some of them are upset and some become physically ill. [Dubuque Telegraph Herald, 11/12/2015] “There are people throwing up in the hall; there are people crying; there are people just staring out the windows,” Studdert will describe.
Personnel Think the Crisis Is Real for 30 Minutes - Since no one in the operations center is able to contact the apparently troubled aircraft, Studdert opens the airline’s crisis center. [Center for Values-Driven Leadership, 3/15/2012] The crisis center, according to journalist and author Jere Longman, is “a terraced, theater-like room that resembled NASA’s Mission Control.” [Longman, 2002, pp. 77] Opening it, according to Studdert, is a significant course of action. When this happens, everyone working for the airline becomes responsible either for running the airline or acting to support the management of the emergency. This means that “3,000 people are put on an immediate activation.” [Center for Values-Driven Leadership, 4/23/2012] United Airlines employees believe one of their planes has crashed for about 30 minutes and then Studdert reveals that the apparent catastrophe is just an exercise scenario. [USA Today, 8/12/2002] He gets on the crisis center’s communications link, which, he will say, “has got 170 stations and people all over the country, all over the world,” and announces, “This has been a no-notice drill; there is no event; everything’s fine.”
Employees Are Furious about the Exercise - The reaction to the exercise in the days after it takes place will be particularly bitter and Studdert will face severe criticism for running it. “I had the board members calling; I had the unions demanding I be fired; I had people telling me I’m the most evil person in the world,” he will recall. [Center for Values-Driven Leadership, 3/15/2012; Center for Values-Driven Leadership, 4/26/2012] Some employees “wanted to kill me,” he will say.
Exercise Has Similarities to the Situation Experienced on September 11 - It is unclear whether Studdert’s exercise has a beneficial or a detrimental effect on the ability of United Airlines to respond to the hijackings 12 days later, on September 11. Studdert will claim that it prepares employees to manage the events of September 11 and reveals weaknesses, such as outdated phone numbers, which are quickly corrected. [Center for Values-Driven Leadership, 4/26/2012; Dubuque Telegraph Herald, 11/12/2015] “It’s amazing, after 9/11… how many people came up to me and thanked me [for running the exercise], because we were ready,” he will say. [Center for Values-Driven Leadership, 3/15/2012] It is possible, however, that it will cause some United Airlines employees to initially think the reports about the terrorist attacks on September 11 are part of another exercise, although accounts are contradictory (see (8:50 a.m.-9:03 a.m.) September 11, 2001). [USA Today, 8/12/2002; Chicago Tribune, 7/16/2003] The scenario of Studdert’s exercise in fact has some similarities with the situation that operations center personnel have to deal with on September 11. On that day, communication with Flight 175—the first of the two United Airlines planes that are hijacked—will be lost (see 8:51 a.m.-8:53 a.m. September 11, 2001) and the plane will have its transponder code changed, although the transponder will not be turned off (see 8:46 a.m.-8:47 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 20-21] Communication will subsequently be lost with Flight 93—the second United Airlines plane to be hijacked (see 9:27 a.m. September 11, 2001 and (9:29 a.m.) September 11, 2001)—and that plane’s transponder will be turned off (see (9:40 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 38-39, 43]
Crisis Center Holds Quarterly Exercises - The United Airlines crisis center usually runs exercises four times a year. Most of these deal with safety issues, but security scenarios are also rehearsed, according to Ed Soliday, the airline’s vice president of safety and security. Typically, the 9/11 Commission will be told, these exercises “are scripted” and based around an act of bioterrorism or an international incident. United Airlines has also practiced hijacking scenarios, according to Soliday, although none of these dealt with the threat of an aircraft being used as a weapon.

Thomas Bergeson.Thomas Bergeson. [Source: Samuel Rogers / United States Air Force]Fighter jets and personnel from the 71st Fighter Squadron, which is stationed at Langley Air Force Base in Virginia, are away in Nevada at the time of the 9/11 attacks, participating in the “Red Flag” training exercise, and only return to base about a week later. [Virginian-Pilot, 9/24/2001; 1st Fighter Association, 2003; Langley Air Force Base, 9/15/2006] Langley AFB is located 130 miles south of the Pentagon, and fighters from there are launched on 9/11 to protect Washington, DC (see (9:25 a.m.-9:30 a.m.) September 11, 2001). [USA Today, 9/16/2001; 9/11 Commission, 7/24/2004, pp. 27] The “host unit” at the base is the 1st Fighter Wing, which includes the 71st Fighter Squadron and two other fighter squadrons: the 27th FS and the 94th FS. [Langley Air Force Base, 11/2003; GlobalSecurity (.org), 2/12/2006] The 71st FS includes about 25 pilots. Its members are participating in Red Flag in preparation for an expected deployment to Iraq this coming December. [Milwaukee Journal Sentinel, 10/19/2001] Col. Thomas Bergeson, the commander of the 71st FS, will later recall, “We had most of our F-15s at Nellis” Air Force Base in Nevada, for the exercise. [Langley Air Force Base, 9/15/2006]
Red Flag - Red Flag is a realistic combat training exercise, held four times a year at Nellis Air Force Base, involving the air forces of the US and its allies. [GlobalSecurity (.org), 10/19/2002; Arkin, 2005, pp. 476] Various aircraft are involved, and more than 100 pilots are participating in the current exercise. [Air Force Magazine, 11/2000; Las Vegas Review-Journal, 8/22/2001] The exercise began on August 11 and ends on September 7. [Las Vegas Review-Journal, 7/28/2001; Las Vegas Review-Journal, 8/22/2001] But the 71st FS pilots only fly their F-15s back to Langley AFB around September 17. [Virginian-Pilot, 9/24/2001]
The 71st Fighter Squadron - The mission of the 71st Fighter Squadron is “to maintain a combat-ready force able to conduct air-superiority operations anywhere in the world for the United States and its allies.” [Langley Air Force Base, 1/2005] Although Langley Air Force Base, where it is stationed, is one of the two “alert sites” upon which NORAD’s Northeast Air Defense Sector (NEADS) can call to get jets quickly launched, NEADS’s alert fighters at the base do not belong to the 71st FS or either of the other two fighter squadrons of the 1st Fighter Wing. Instead, the two alert jets are part of a small detachment from Fargo, North Dakota’s 119th Fighter Wing, which is located on the opposite side of the runway to the central facilities of Langley AFB. [9/11 Commission, 7/24/2004, pp. 17; Spencer, 2008, pp. 114] However, some F-15s belonging to the 71st FS are launched from Langley AFB on 9/11, following the attacks, to patrol the skies of the East Coast. Some of the 71st FS jets that are deployed to Nevada are the first fighters to get airborne to patrol Las Vegas and southern California in response to the attacks. [Langley Air Force Base, 1/2005; 1st Fighter Association, 3/14/2006]
Other Units Away on 9/11 - The 94th Fighter Squadron, which is also based at Langley AFB, is away on September 11 as well, for a 90-day combat deployment to Saudi Arabia to enforce the no-fly zone over southern Iraq (see September 2001). [BBC, 12/29/1998; 1st Fighter Association, 2003] Around this same time, members of the 121st Fighter Squadron of the District of Columbia Air National Guard (DCANG) also participate in Red Flag, and only return to their base three days before 9/11 (see Late August-September 8, 2001). [Washington Post, 4/8/2002; Spencer, 2008, pp. 156]

Members of the FBI’s Hostage Rescue Team.Members of the FBI’s Hostage Rescue Team. [Source: Training and Simulation Journal]The FBI’s Critical Incident Response Group (CIRG) goes to California for a week of training and is therefore stranded away from Washington, DC, when it is required to help in the response to the 9/11 terrorist attacks. [USA Today, 9/11/2001; Darling, 2010, pp. 75] The CIRG is “the unit that coordinates the FBI’s rapid response to crisis incidents, including terrorist attacks,” according to Major Robert Darling of the White House Military Office. Its members arrive in San Francisco this evening to participate in a week of special weapons and tactics (SWAT)-related field training. [Darling, 2010, pp. 74-75] While the 9/11 attacks are underway, NBC News will report that the FBI is in a state of “chaos,” partly because of the CIRG being stranded in California (see 10:03 a.m. September 11, 2001). [NBC 4, 9/11/2001] On the afternoon of September 11, the White House will arrange for the CIRG to return to Washington as a matter of priority (see (3:50 p.m.) September 11, 2001), and the unit’s members will be flown back later that day (see Late Afternoon September 11, 2001). [Darling, 2010, pp. 73-76]
Unit Created to Respond to Terrorist Incidents - The CIRG would be a valuable resource for responding to the 9/11 attacks. The unit was established in 1994 “to give the FBI the ability to respond with the tactical and investigative expertise needed in a major terrorist incident,” according to the Congressional Research Service. It has crisis managers, hostage negotiators, behavioral scientists, surveillance assets, and agents that it can utilize. [United States General Accounting Office, 9/1997, pp. 40 pdf file; Brake, 4/19/2001, pp. 9-10 pdf file] The CIRG also has a “seven-step approach” it follows, which uses “active listening” to defuse a crisis. According to the Indian Express, “by showing support and empathy, [CIRG] negotiators often can talk a hijacker into surrendering largely by listening.” [Law Enforcement Bulletin, 8/1997; Indian Express, 12/29/1999]
Hostage Rescue Team Serves as Domestic Counterterrorism Unit - The tactical centerpiece of the CIRG is the Hostage Rescue Team (HRT), a full-time team headquartered in Quantico, Virginia, that is able to deploy to any location within four hours of notification. Its skills include hostage rescue tactics, precision shooting, and tactical site surveys. [United States General Accounting Office, 9/1997, pp. 40 pdf file; Brake, 4/19/2001, pp. 10 pdf file] The HRT was created to give civilian law enforcement agencies a counterterrorist community comparable to that which exists in the military. Many of its members have a military background. [Training and Simulation Journal, 2/2009] According to Darling, the HRT is ”the domestic counterterrorism unit, offering a tactical resolution option in hostage and high-risk law enforcement situations.” [Darling, 2010, pp. 7]

Jackie Chan.Jackie Chan. [Source: Reuters]A scene for a Hollywood movie about a terrorist plot to blow up the World Trade Center was originally scheduled to be filmed at the top of one of the Twin Towers at this time, but the filming has been canceled because the script for the scene is late to arrive. [ABC News, 9/19/2001; Empire, 9/19/2001; Orlando Sentinel, 9/27/2002] The action-comedy movie, titled Nosebleed, which was written in 1999 (see February 1999-September 11, 2001), is set to feature the well-known martial artist and actor Jackie Chan as a window washer at the WTC who uncovers a terrorist plot to bomb the Twin Towers. [Variety, 2/7/1999; Entertainment Weekly, 9/24/2001]
Actor 'Would Probably Have Died' if Filming Took Place - Chan will later tell the Hong Kong newspaper Oriental Daily News, “Filming was scheduled to have taken place at 7:00 a.m. [on September 11] and… I had to be at the top of one of the towers for one of the scenes.” [ABC News, 9/19/2001; Empire, 9/19/2001] The scene, Chan will say, was going to be filmed at the “Top of the World restaurant.” [Orlando Sentinel, 9/27/2002] Presumably he is referring to Windows on the World, the restaurant at the top of the North Tower. Everyone who is in Windows on the World when Flight 11 hits the North Tower at 8:46 a.m. (see 8:46 a.m. September 11, 2001) will subsequently die. [NPR, 9/11/2003] Chan will comment, “I would probably have died if the shooting had gone ahead as planned.” Today’s filming at the WTC has been canceled, reportedly because the script for the scene that would have been filmed is late. [ABC News, 9/19/2001; Empire, 9/19/2001] “The action was good, but, somehow, the script not ready,” Chan will say.
Actor Is in Canada for Another Film - Instead of doing the scene for Nosebleed, Chan is in Toronto, Canada, where filming began the previous day for another movie he is starring in. That movie, The Tuxedo, is an action-comedy that Steven Spielberg is involved in producing. Chan will say of The Tuxedo, “I only did this movie because Steven Spielberg asked me himself.” [Reuters, 6/17/2001; Canoe, 7/11/2001; Orlando Sentinel, 9/27/2002] He will recall learning of the attacks in New York during filming, saying: “After the first shot, I turned around and everyone was looking at one monitor, and nobody had responded to me. They said, ‘Jackie, a plane crashed into the World Trade Center.’ Then we [saw] the second plane crash. We knew it was a terrorist attack and everyone started crying.” Chan will add, “The whole day I was like a walking dead man.” [Columbia Chronicle, 9/23/2002]
Actor Learned 'Secrets' of the WTC in Preparation for Film - Chan has done a lot of groundwork for Nosebleed. “We had visited the [WTC] before September 11,” he will recall. “The producer. My manager. We had dinner upstairs. We were getting all kinds of information. I was going to play a window washer, so they were telling me things like how many windows the building had.” Chan has therefore learned “the ‘secrets’ of the towers—how air pressure was regulated with doors that might be useful as gags in one of his trademark fights—which sides of the buildings one could work on to avoid the wind,” according to the Orlando Sentinel. [Orlando Sentinel, 9/27/2002; Rocky Mountain News, 9/28/2002] Production of Nosebleed will be canceled as a result of the 9/11 attacks. [PBS, 10/24/2001; Village Voice, 12/4/2001]

The specially modified C-135 nicknamed ‘Speckled Trout.’The specially modified C-135 nicknamed ‘Speckled Trout.’ [Source: United States Air Force]General Henry Shelton, the chairman of the Joint Chiefs of Staff, takes off to fly to Europe for a NATO conference, and will therefore be away from the US when the 9/11 terrorist attacks occur. [Giesemann, 2008, pp. 20, 22; Shelton, Levinson, and McConnell, 2010, pp. 430-433] Shelton is scheduled to attend a meeting of the Military Committee—NATO’s highest military authority—in Budapest, Hungary, on September 12, to discuss the situation in the Balkans, the European Security and Defense Identity, and NATO’s new force structure. On his return journey, he is set to stop in London, Britain, to be knighted by the Queen. [North Atlantic Treaty Organization, 9/10/2001; North Atlantic Treaty Organization, 9/11/2001; Shelton, Levinson, and McConnell, 2010, pp. 430] Shelton takes off from Andrews Air Force Base, just outside Washington, DC, on a specially modified C-135 (the military version of a Boeing 707) nicknamed “Speckled Trout.” Normally he flies on a VIP Boeing 757 often used by the vice president, but that aircraft is presently unavailable, so he is flying instead on the C-135, which is usually reserved for the Air Force chief of staff. Those accompanying Shelton on the flight include his wife, Carolyn; his executive assistant, Colonel Doug Lute; his aides, Master Sergeant Mark Jones and Lieutenant Commander Suzanne Giesemann; and his personal security agent, Chief Warrant Officer Marshall McCants. [Giesemann, 2008, pp. 20-22; Shelton, Levinson, and McConnell, 2010, pp. 431, 434] When Shelton is out of the country, General Richard Myers, the vice chairman of the Joint Chiefs of Staff, is designated by law as acting chairman of the Joint Chiefs of Staff in his place. Shelton will later recall, “Until I crossed back into United States airspace, all the decisions would be [Myers’s] to make, in conjunction with Secretary [of Defense Donald] Rumsfeld and the president.” [Myers, 2009, pp. 10; Shelton, Levinson, and McConnell, 2010, pp. 432] After learning of the attacks in New York, Shelton will give the order for his plane to return to the US (see (8:50 a.m.-10:00 a.m.) September 11, 2001). [Giesemann, 2008, pp. 22-23; Shelton, Levinson, and McConnell, 2010, pp. 431] However, the plane will repeatedly be denied permission to enter US airspace (see (After 9:45 a.m.) September 11, 2001) and will only land back in the US at 4:40 p.m. (see 4:40 p.m. September 11, 2001). Shelton will only arrive at the National Military Command Center at the Pentagon an hour after that (see 5:40 p.m. September 11, 2001).

At Langley Air Force Base in Virginia, one of the pilots that will take off to defend Washington in response to the terrorist attacks (see (9:25 a.m.-9:30 a.m.) September 11, 2001) asks to be removed from “alert” status later this morning, so he and another pilot can participate in a training mission. [Associated Press, 8/19/2002; Spencer, 2008, pp. 116] Being on “alert” means that a pilot’s fighter jet is kept on the runway, armed, fueled up, and ready to take off within minutes if called upon. [Air Force Magazine, 2/2002; Bergen Record, 12/5/2003]
Pilot Requests 'Download' - The pilot, Major Dean Eckmann, calls NORAD’s Northeast Air Defense Sector (NEADS) and requests that he be removed from alert status at 11:00 a.m. He wants to be able to join in with a scheduled training mission being conducted from Langley Air Force Base, along with another pilot from his unit, Captain Craig Borgstrom. (Borgstrom is not one of the unit’s alert pilots, but will take off along with Eckmann in response to the terrorist attacks.) According to author Lynn Spencer, such requests for removal from alert status—known as “download”—are customary, “since the detachment typically flies two training missions each week, and as long as the other NORAD alert sites on the East Coast—at Otis [Air National Guard Base] on Cape Cod and Homestead [Air Reserve Base] in Florida—are up on alert, the requests are generally approved.” [Spencer, 2008, pp. 116 and 141-144]
Alert Duty Usually Uneventful - The alert unit at Langley Air Force Base is in fact part of the North Dakota Air National Guard’s 119th Fighter Wing, which has a small detachment at Langley, located away from the base’s central facilities. The unit is housed in two cramped buildings, and has just four aircraft and 18 full-time members of staff. [Spencer, 2008, pp. 114] According to journalist and author Jere Longman, being on alert duty is usually fairly uneventful for the pilots involved: “Protecting American airspace from attack was not a demanding job before September 11.… A week at Langley was a time to relax, watch television, work out, spend time on the computer, catch up on business. Like firemen, the pilots sat and waited for something to happen. When it did, they were usually scrambled to escort Navy jets with transponder problems to their home bases. Or to find doctors lost over the ocean in their Beechcraft Bonanzas. Or, occasionally, to sniff out drug runners. It was a sleepy job. Dozing for dollars, they called it.” [Longman, 2002, pp. 64]

Shortly after air traffic controllers ask Flight 11 to climb to 35,000 feet, its transponder stops transmitting. A transponder is an electronic device that identifies a plane on a controller’s screen and gives its exact location and altitude. Among other vital functions, it is also used to transmit a four-digit emergency hijack code. Flight control manager Glenn Michael later says, “We considered it at that time to be a possible hijacking.” [Christian Science Monitor, 9/13/2001; MSNBC, 9/15/2001; Associated Press, 8/12/2002] Initial stories after 9/11 suggest the transponder is turned off around 8:13 a.m., but Pete Zalewski, the air traffic controller handling the flight, later says the transponder is turned off at 8:20 a.m. [MSNBC, 9/11/2002] The 9/11 Commission places it at 8:21 a.m. [9/11 Commission, 6/17/2004] Colonel Robert Marr, head of NEADS, claims the transponder is turned off some time after 8:30 a.m. where the Flight 11 hijack was first detected a.m. [ABC News, 9/11/2002]

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). [9/11 Commission, 7/24/2004, pp. 5, 453] The four American Airlines managers will also tell the 9/11 Commission, “In the event that the [American Airlines] SOC was aware that it was the first to know about an incident [with an aircraft], the protocol would have been for the SOC manager on duty [i.e. Marquis] to have immediately autodialed to the Herndon manager on duty [i.e. Ben Sliney] with the information.” However, the FAA “knew what was going on because of the intercepted communications from the cockpit.” [9/11 Commission, 11/19/2003 pdf file] (FAA air traffic controllers have been aware of problems with Flight 11 since around 8:14 a.m., when they lost communication with the plane (see 8:14 a.m.-8:24 a.m. September 11, 2001), and they subsequently hear communications made by the hijackers on the plane, beginning at 8:24 a.m. (see 8:24 a.m. September 11, 2001).

Pete Zalewski.Pete Zalewski. [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).

Boston flight control reportedly “notifies several air traffic control centers that a hijack is taking place.” [Guardian, 10/17/2001] This is immediately after Boston controllers heard a transmission from Flight 11, declaring, “We have some planes” (see 8:24 a.m. September 11, 2001), and would be consistent with a claim later made to the 9/11 Commission by Mike Canavan, the FAA’s associate administrator for civil aviation security. He says, “[M]y experience as soon as you know you had a hijacked aircraft, you notify everyone.… [W]hen you finally find out, yes, we do have a problem, then… the standard notification is it kind of gets broadcast out to all the regions.” [9/11 Commission, 5/23/2003] An early FAA report will say only that Boston controllers begin “inter-facility coordination” with New York air traffic control at this time [Federal Aviation Administration, 9/17/2001 pdf file] , but the New York Times reports that controllers at Washington Center also know “about the hijacking of the first plane to crash, even before it hit the World Trade Center.” [New York Times, 9/13/2001] However, the Indianapolis flight controller monitoring Flight 77 claims to not know about this or Flight 175’s hijacking twenty minutes later at 8:56 a.m. (see 8:56 a.m. September 11, 2001). Additionally, the flight controllers at New York City’s La Guardia airport are never told about the hijacked planes and learn about them from watching the news. [Bergen Record, 1/4/2004] Boston Center also begins notifying the FAA chain of command of the suspected Flight 11 hijacking at this time (see 8:25 a.m. September 11, 2001), but it does not notify NORAD for another 6-15 minutes, depending on the account (see (8:37 a.m.) September 11, 2001).

A Sikorsky S-76A helicopter flying over New York.
A Sikorsky S-76A helicopter flying over New York. [Source: Sikorsky]A helicopter is tracked on radar apparently crashing into the World Trade Center, according to a report later given by a New York air traffic controller over an FAA teleconference.
Helicopter Is 'the Only Target that We Saw ... to Fly into the Trade Center' - At around 10:15 a.m., Tom White, an operations manager at the FAA’s New York Terminal Radar Approach Control (TRACON), will tell those on the FAA teleconference that his facility tracked a Sikorsky helicopter that had taken off from the airport in Poughkeepsie, New York, and this helicopter appeared to fly into the WTC at 8:27 a.m. (see (10:15 a.m.) September 11, 2001). White will add that, after replaying radar information, it is concluded that the helicopter is “the only target that we saw in the vicinity of the Trade Center at 12:27 [Zulu time, or 8:27 a.m. Eastern time] to fly into the Trade Center.” [Federal Aviation Administration, 9/11/2001; 9/11 Commission, 5/21/2004] (However, the first crash at the WTC will not occur until 8:46 a.m. (see 8:46 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 7] ) The “Poughkeepsie airport” the helicopter took off from is presumably Dutchess County Airport. Sikorsky reportedly bases a fleet of its S-76 helicopters at Dutchess County Airport, “dispatching them to the New York metro areas as needed.” [Site Selection, 5/2000; Aviation International News, 8/1/2003] Poughkeepsie is about 70 miles north of New York City. [Pittsburgh Post-Gazette, 2/3/2008]
Helicopter 'Consistent with the Speed' of What Hits WTC - White will say the helicopter’s tail number is N7601S, that it departed the Poughkeepsie airport at 8:03 a.m., and that it then headed south at a speed of around 160 knots, or 184 miles per hour. He will add: “The tower [presumably the air traffic control tower at the Poughkeepsie airport] says the only thing they had southbound at that time was a Sikorsky helicopter, which is consistent with the speed that we followed it down.… They’re saying they replayed the radar and it’s consistent with the speed of what went into the [WTC] tower.” [Federal Aviation Administration, 9/11/2001] (However, an analysis by the US government will later estimate that Flight 11 hits the WTC at 494 miles per hour, or 429 knots, which is significantly faster than the helicopter was flying. [New York Times, 2/23/2002] )
Mistaken Information Later Corrected - It will apparently take until early afternoon for the suspicions about the Sikorsky helicopter hitting the WTC to be dismissed. An FAA chronology of this day’s events will state that at 1:00 p.m., the “Sikorsky helicopter” is “now believed not to have hit the WTC.” [Federal Aviation Administration, 1/2/2002] Another FAA chronology will state that at 1:04 p.m., it is reported that the Sikorsky helicopter “landed 20 minutes early, normal GE run at 12:28Z [i.e. 8:28 a.m. Eastern time] to WTC.” (It is unclear what is meant by “normal GE run.”) [Federal Aviation Administration, 9/11/2001]

[Source: CNN]The FAA’s Boston Center calls the FAA Command Center and says it believes Flight 11 has been hijacked and is heading toward the New York Center’s airspace. The Command Center immediately establishes a teleconference between the Boston, New York, and Cleveland air traffic control centers, so Boston can help the other centers understand what is happening, in case Flight 11 should enter their airspace. Minutes later, in line with the standard hijacking protocol, the Command Center will pass on word of the suspected hijacking to the FAA’s Washington headquarters (see 8:32 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 19; 9/11 Commission, 8/26/2004, pp. 11; Spencer, 2008, pp. 21]
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]

Steve Bongardt.Steve Bongardt. [Source: Government Matters]Steve Bongardt, an agent at an FBI office in Manhattan, reads a report on his computer about Osama bin Laden reopening his underground facility in Afghanistan and he will subsequently determine that this incident is related to the attacks on the World Trade Center. [Wright, 2006, pp. 356-357; Graff, 2011, pp. 309-310] Bongardt is a member of the FBI’s I-49 squad. [Wright, 2006, pp. 377] The squad is focused on bin Laden and al-Qaeda’s central command. It is based in an office on the eighth floor at 290 Broadway, across the street from the FBI’s New York field office at 26 Federal Plaza. [Graff, 2011, pp. 205-206] Bongardt is one of the first people to arrive at the office this morning, coming into work sometime before 8:30 a.m. He turns on his computer and reads some of the day’s intelligence. He is puzzled by one particular piece of information he sees. “A report had Osama bin Laden reopening his large underground facility at Tora Bora in Afghanistan and sprucing it up,” journalist and author Garrett Graff will write. According to author Lawrence Wright, the report states that “the al-Qaeda camps in Tora Bora [are] being revitalized.” [Wright, 2006, pp. 356-357; Graff, 2011, pp. 309] The Tora Bora encampment is a “natural and manmade fortress of caves and bunkers,” according to the Chicago Tribune. It comprises a “series of rooms and tunnels,” and can “comfortably house 1,000 people,” according to an Afghan who visited the complex a few months ago. [Chicago Tribune, 11/28/2001] “That can’t be good,” Bongardt thinks upon reading the report. “What the hell is [bin Laden] doing?” he wonders. Bongardt will feel the room shake when Flight 11 crashes into the WTC, at 8:46 a.m. (see 8:46 a.m. September 11, 2001), and promptly head out of the building. He will realize what has happened when he sees that both of the Twin Towers are on fire and notices a massive jetliner engine lying on the street. He will then connect what is occurring to the report he read on his computer. He will understand that “this was the work of bin Laden,” according to Wright. “This is al-Qaeda. This is why they’re polishing up Tora Bora,” he will think. [Wright, 2006, pp. 357-359; Graff, 2011, pp. 309-310]

[Source: NASA]A special aircraft operated by NASA is in the air over western New York State at the time of the terrorist attacks and, at one point, a large aircraft, which those on board later learn is the hijacked Flight 93, flies less than 1,000 feet below it. [Space Center Roundup, 9/2002 pdf file] The plane, NASA 931, is a modified KC-135—a four-engine military aircraft similar to the Boeing 707. [National Aeronautics and Space Administration, 10/2000, pp. 28; National Aeronautics and Space Administration, 10/29/2004] It is used by NASA for reduced gravity research, and is known as the “Weightless Wonder” or sometimes the “Vomit Comet.” The aircraft creates weightless conditions for brief periods by flying up and down in large parabolic arcs. [NASAexplores, 1/30/2003] It is regularly operated from NASA’s Glenn Research Center in Cleveland, Ohio, next to Cleveland Hopkins International Airport, and usually flies four days a week. [National Aeronautics and Space Administration, 10/2000, pp. 140; National Journal's Technology Daily, 11/27/2002; National Aeronautics and Space Administration, 10/29/2004] A typical flight lasts two to three hours and consists of the plane flying 40 to 60 parabolas. [NASAexplores, 1/30/2003]
Scientists from Houston Conducting Microgravity Experiments - A team of scientists from NASA’s Johnson Space Center in Houston, Texas, has flown to Cleveland to conduct microgravity experiments on the KC-135. [Cleveland Free Times, 9/6/2006] Dominic Del Rosso, the test director on the plane, will later recall that the team is flying over western New York State when the terrorist attacks occur. During the routine mission, the KC-135 cruises back and forth along the New York shore of Lake Ontario, climbing and descending to create a freefall condition to simulate microgravity. Del Rosso will comment, “To think that this type of maneuver might ever seem threatening never crossed my mind until [September 11].” The plane’s crew members are notified at some point that a large plane is intersecting their flight path less than 1,000 feet below them, instead of the usual 2,000-foot minimum distance. They will later learn that this aircraft is the hijacked Flight 93, which crashes in Pennsylvania (see (10:06 a.m.) September 11, 2001). Del Rosso will recall, “After the unwanted flyby, we landed having no idea why or what was going on.” [Space Center Roundup, 9/2002 pdf file] The scientists are unable to return to Houston on this day, as scheduled, after the FAA orders all planes to land (see (9:45 a.m.) September 11, 2001), and so have to be put up in a hotel in Cleveland.

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).

Following the previous two transmissions, controller Pete Zalewski had put the plane’s frequency on speakers so that others at the center could hear (see 8:24 a.m. September 11, 2001).

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]

Tech. Sgt. Jeremy Powell.Tech. Sgt. Jeremy Powell. [Source: Scott A. 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]

Employees at the American Airlines Southeastern Reservations Office in Cary, North Carolina, lose communication with Betty Ong, a flight attendant on the hijacked Flight 11. [American Airlines, 9/11/2001, pp. 20-22; 9/11 Commission, 7/24/2004, pp. 5-6]
Ong Stops Responding to Questions - For about the last 25 minutes, Ong has been on the phone with a number of employees at the reservations office, and has been providing them with information about the trouble on her plane. [9/11 Commission, 8/26/2004, pp. 8] But now she stops responding to their communications. Nydia Gonzalez, one of the reservations office employees, continues questioning Ong. She says: “What’s going on Betty? Betty, talk to me. Betty, are you there? Betty?” Receiving no response, she asks her colleague Winston Sadler, who is also participating in the call, “Do you think we lost her?” On another phone line, Gonzalez immediately notifies a manager at the American Airlines System Operations Control center in Texas that contact with Ong has been lost (see 8:44 a.m. September 11, 2001). [American Airlines, 9/11/2001, pp. 20-22; 9/11 Commission, 8/26/2004, pp. 14]
Ong Asked Airline Employees to 'Pray for Us' - Toward the end of the call, Ong said repeatedly to the reservations office employees: “Pray for us. Pray for us.” [ABC News, 7/18/2002] Gonzalez will say in an interview later today that Ong’s final words, before the call ends, were, “Oh my God, the flight, it’s going down, it’s going down.” [Federal Bureau of Investigation, 9/11/2001, pp. 1-8] But in a subsequent interview, she will say that before the call ends, Ong “started to cry” and then her final words were, “Oh God, oh God, what is going on?” [Federal Bureau of Investigation, 9/12/2001, pp. 69-71] The reservations office employees have lost communication with Ong by 8:44 a.m., according to the 9/11 Commission Report. [9/11 Commission, 7/24/2004, pp. 6] But according to a summary of phone calls from the hijacked flights presented at the 2006 trial of Zacarias Moussaoui, the call from Ong began at 8:18 a.m. and 47 seconds, and lasts exactly 27 minutes, meaning it ends at 8:45 a.m. and 47 seconds. [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] Flight 11 will crash into the World Trade Center less than a minute after that, at 8:46 a.m. (see 8:46 a.m. September 11, 2001).

Amy Sweeney, a flight attendant on Flight 11, gives updates over the phone to Michael Woodward, an American Airlines flight services manager at Logan International Airport in Boston, as her plane approaches the World Trade Center, and then, after she reports that the plane is flying “very, very low,” the line goes dead. [Federal Bureau of Investigation, 9/13/2001, pp. 1-2; 9/11 Commission, 7/24/2004, pp. 6-7] Sweeney has been on the phone with the American Airlines flight services office at Logan Airport since 8:32 a.m., describing to Woodward the trouble on her plane (see (8:32 a.m.-8:44 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 11]
Sweeney Says Plane Is 'in a Rapid Descent' - She now tells Woodward: “Something is wrong. We are in a rapid descent.” She says her plane is flying “all over the place.” [9/11 Commission, 1/25/2004 pdf file; 9/11 Commission, 8/26/2004, pp. 14] Around this time, Woodward tells Nancy Wyatt, another employee in the flight services office, that Sweeney has “started screaming that there’s something wrong with the airplane.” He adds: “In other words… [the original pilot is] not flying the airplane. They’re not flying the airplane.” [American Airlines, 9/11/2001, pp. 34-41]
Sweeney Says Plane Is Flying 'Very Low' - Woodward asks Sweeney to look out of the window to see if she can determine where her plane is. [9/11 Commission, 1/25/2004 pdf file; 9/11 Commission, 8/26/2004, pp. 14] In an interview with the FBI a couple of days later, Woodward will say that Sweeney tells him: “I see water. I see buildings. We’re very, very low. Oh my God.” [Federal Bureau of Investigation, 9/13/2001, pp. 1-2] In 2004, he will give a slightly different account, telling the 9/11 Commission that Sweeney says: “We are flying low. We are flying very, very low. We are flying way too low.” Seconds later she says, “Oh my God, we are way too low.” [9/11 Commission, 1/25/2004 pdf file; 9/11 Commission, 8/26/2004, pp. 14] Sweeney says “Oh my God” after taking “a very slow, deep breath,” Woodward will tell ABC News. She says these final words “[v]ery slowly, very calmly, very quietly. It wasn’t in panic,” Woodward will say.
Call Suddenly Cut Off - Woodward then hears what he will describe as “very, very loud static on the other end” of the line. [ABC News, 7/18/2002] After a short time, the line goes dead. [Federal Bureau of Investigation, 9/13/2001, pp. 1-2] Woodward looks up from the phone and tells everyone else in the office that the line has died. [Federal Bureau of Investigation, 9/13/2001, pp. 3-4] Wyatt is on the phone with Ray Howland, an employee at the American Airlines System Operations Control center in Fort Worth, Texas, and has been passing on to him the information that Sweeney was providing to Woodward (see 8:40 a.m.-8:48 a.m. September 11, 2001). She now informs Howland, “Okay, we just lost connection” with Sweeney. [American Airlines, 9/11/2001, pp. 34-41; Rutgers Law Review, 9/7/2011, pp. 14 pdf file]
Flight Services Office Personnel Learn of Crash at WTC - Shortly after Sweeney’s call is cut off, Woodward’s operational manager, Craig Kopetz, will enter the flight services office and say that a plane has just crashed into the WTC. Woodward will not initially connect this news with the crisis he has been dealing with. [Federal Bureau of Investigation, 9/13/2001, pp. 1-2; ABC News, 7/18/2002] Those in the flight services office will then go to their command center. “Approximately 15 minutes later,” according to Elizabeth Williams, one of Woodward’s colleagues, the group will realize that “Flight 11 was the same flight which crashed into the WTC.” [Federal Bureau of Investigation, 9/13/2001, pp. 3-4] The call between Sweeney and Woodward lasts “approximately 12 minutes” and ends at around 8:44 a.m., according to the 9/11 Commission.

Hijackers Mohamed Atta Waleed Alshehri, Wail Alshehri, Abdulaziz Alomari, and Satam Al Suqami presumably are killed instantly, and many more in the tower will die over the next few hours. Seismic records pinpoint the crash at 26 seconds after 8:46 a.m. [CNN, 9/12/2001; New York Times, 9/12/2001; 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; USA Today, 8/12/2002; Associated Press, 8/21/2002; Newsday, 9/10/2002] The NIST report states the crash time to be 8:46:30. [National Institute of Standards and Technology, 9/2005, pp. 19] The 9/11 Commission Report states the crash time to be 8:46:40. [9/11 Commission, 7/24/2004, pp. 7] Investigators believe the plane still has about 10,000 gallons of fuel (see 8:57 a.m. September 11, 2001). [New York Times, 5/26/2002] The plane strikes the 93rd through 99th floors in the 110-story building. No one above the crash line survives; approximately 1,360 people die. Below the crash line, approximately 72 die and more than 4,000 survive. Both towers are slightly less than half full at the time of the attack, with between 5,000 to 7,000 people in each tower. This number is lower than expected. Many office workers have not yet shown up to work, and tourists to the observation deck opening at 9:30 A.M. have yet to arrive. [USA Today, 12/20/2001; National Institute of Standards and Technology, 9/2005, pp. 20-22] The impact severs some columns on the north side of the North Tower. Each tower 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 weighs 283,600 lb and is traveling at an estimated speed of around 430 mph (see October 2002-October 2005), severs 35 of the building’s 236 perimeter columns and damages another two. The damage to the South Tower’s perimeter will be similar (see 9:03 a.m. September 11, 2001). [National Institute of Standards and Technology, 9/2005, pp. 5-9, 20, 22] The perimeter columns bear about half of the tower’s weight, so this damage reduces its ability to bear gravity loads by about 7.5 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 have damaged the core even after crashing through the exterior wall. According to the National Institute of Standards and Technology (NIST): “Moving at 500 mph, an engine broke any exterior column it hit. If the engine missed the floor slab, the majority of the engine core remained intact and had enough residual momentum to sever a core column upon direct impact.” [National Institute of Standards and Technology, 9/2005, pp. 107] According to NIST’s base case computer model, three of the core columns are severed and another ten suffer some damage. [National Institute of Standards & Technology, 9/2005, pp. 189 pdf file] If this is accurate, it means that the impact damage to the core reduces the Tower’s strength by another approximately 7.5 percent, meaning that the building loses about 15 percent of its strength in total. This damage will be cited after 9/11 by NIST and others researchers as an event contributing to the building’s collapse (see October 23, 2002 and October 19, 2004). In addition, some of the fireproofing on the steel columns and trusses may be dislodged. The original fireproofing on the fire floors was mostly Blazeshield DC/F, but some of the fireproofing on the flooring has recently been upgraded to Blazeshield II, which is about 20 percent denser and 20 percent more adhesive. [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 NIST will estimate the damage to it using a computer model. Its severe case model (see (October 2002-October 2005)) will predict that 43 of the 47 core columns are stripped of their fireproofing on one or more floors and that fireproofing is stripped from trusses covering 60,000 ft2 of floor area, the equivalent of about one and a half 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. 23] According to NIST, more fireproofing is stripped from the South Tower (see 9:03 a.m. September 11, 2001).

John Odermatt.John Odermatt. [Source: Queens Gazette]New York City’s Office of Emergency Management (OEM) activates its Emergency Operations Center (EOC) on the 23rd floor of World Trade Center Building 7. The OEM is responsible for managing the city’s response to major incidents, including terrorist attacks. [9/11 Commission, 7/24/2004, pp. 283-284, 293] Its personnel arrived at WTC 7, where it has offices, early this morning to prepare for Tripod, a major biological terrorism training exercise scheduled for September 12 (see September 12, 2001). [Jenkins and Edwards-Winslow, 9/2003, pp. 15 pdf file]
Staffer Is Told to Open the Operations Center - OEM Commissioner John Odermatt and Richard Bylicki, a police sergeant assigned to the OEM, heard the explosion when Flight 11 crashed into the WTC, at 8:46 a.m. (see 8:46 a.m. September 11, 2001). As they look out of the window at the burning North Tower, Odermatt debriefs Bylicki and instructs him to open the EOC for a fully staffed operation. Bylicki therefore sets about activating the operations center. [Bylicki, 6/19/2003]
Staffers Call Agencies and Tell Them to Send Their Representatives - EOC personnel start contacting agencies, including the New York Fire and Police Departments and the Department of Health, and instruct them to send their designated representatives to the center. They also call the State Emergency Management Office (SEMO) and the Federal Emergency Management Agency (FEMA), which they ask to send at least five federal urban search and rescue teams.

[Bylicki, 6/19/2003]
Activation Proceeds without Any Problems - EOC personnel initially struggle to make sense of what has happened at the Twin Towers. [Wachtendorf, 2004, pp. 77] However, the activation apparently proceeds without any problems. Firefighter Timothy Brown, a supervisor at the OEM, is instructed by Calvin Drayton, a deputy director with the OEM, to go up to the 23rd floor of WTC 7 and make sure that personnel are getting the EOC up and running, and the Watch Command is being properly supervised. He goes up to the 23rd floor and first checks the Watch Command. He sees that its supervisor, Mike Lee, has things under control. Then, in the EOC, he sees Michael Berkowitz, a supervisor with the OEM, powering up all the computers and television screens necessary to handle the emergency, and beginning to notify the dozens of agencies that need to send representatives to the center. Berkowitz tells Brown he has the manpower he needs to get the center up and running. “I was very comfortable that OEM was beginning to do what we do in a major emergency,” Brown will later recall. Activating the EOC is something OEM personnel have “drilled for and drilled for and drilled for… and so we were very good at it,” he will comment.

Center Is Designed for Managing a Crisis - The EOC, which opened in 1999 (see June 8, 1999), is a state-of-the-art facility designed to operate as a stand-alone center from which the city government can operate during a crisis. [City of New York, 2/18/2001] It is one of the most sophisticated facilities of its type in the world. It includes a communications suite, a conference room, a press briefing room, and a large number of staff offices, and has numerous computer-equipped workstations. [Disasters, 3/2003 pdf file] It has enough seating for 68 agencies to operate during an emergency. [City of New York, 2/18/2001] However, it will be evacuated at 9:30 a.m. due to reports of further unaccounted-for planes, according to the 9/11 Commission Report (see (9:30 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 305] Other accounts will indicate that it may be evacuated at an earlier time, possibly even before the second crash at the WTC occurs (see (Soon After 8:46 a.m.-9:35 a.m.) September 11, 2001 and (Shortly Before 9:03 a.m.) September 11, 2001).

The FAA’s Command Center in Herndon, Virginia, establishes a teleconference with FAA facilities in the New York area. These facilities are the New York Center, the New York Terminal Radar Approach Control, and the Eastern Regional Office. The participants in the teleconference jointly decide to divert all air traffic that would otherwise enter the New York area, either to land or to overfly. Linda Schuessler, the deputy director of system operations at the Command Center, will later describe, “They [New York area air traffic control personnel] would continue to work what they’d been working, but we wouldn’t give them any more.” The teleconference participants’ decision does not affect takeoffs from the New York area. After the second World Trade Center tower is hit at 9:03 a.m., the Command Center will expand this teleconference to include FAA headquarters and other agencies (see 9:06 a.m. and After September 11, 2001).

The National Military Joint Intelligence Center.The National Military Joint Intelligence Center. [Source: Joseph M. Juarez / Defense Intelligence Agency]Lieutenant Colonel Mark Stuart, an intelligence officer at NORAD’s Northeast Air Defense Sector (NEADS), calls the National Military Joint Intelligence Center (NMJIC) at the Pentagon regarding the hijacking of Flight 11, but the center is unable to provide him with any more information than he already has. [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. [9/11 Commission, 10/30/2003 pdf file] The NMJIC, located in the Joint Staff area of the Pentagon, constantly monitors worldwide developments for any looming crises that might require US involvement. [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]

According to a statement by two high-level FAA officials, “Within minutes after the first aircraft hit the World Trade Center, the FAA immediately established several phone bridges [i.e., telephone conference calls] that included FAA field facilities, the FAA command center, FAA headquarters, [Defense Department], the Secret Service, and other government agencies.” The FAA shares “real-time information on the phone bridges about the unfolding events, including information about loss of communication with aircraft, loss of transponder signals, unauthorized changes in course, and other actions being taken by all the flights of interest, including Flight 77. Other parties on the phone bridges in turn shared information about actions they were taken.” The statement says, “The US Air Force liaison to the FAA immediately joined the FAA headquarters phone bridge and established contact with NORAD on a separate line.” [9/11 Commission, 5/23/2003] Another account says the phone bridges are “quickly established” by the Air Traffic Services Cell (ATSC). This is a small office at the FAA’s Herndon Command Center, which is staffed by three military officers at the time of the attacks (see (Between 9:04 a.m. and 9:25 a.m.) September 11, 2001). It serves as the center’s liaison with the military. According to Aviation Week and Space Technology, the phone bridges link “key players, such as NORAD’s command center, area defense sectors, key FAA personnel, airline operations, and the NMCC.” [Aviation Week and Space Technology, 6/10/2002; 9/11 Commission, 6/17/2004] According to an FAA transcript of employee conversations on 9/11, one of the phone bridges, between the FAA Command Center, the operations center at FAA headquarters, and air traffic control centers in Boston and New York, begins before Flight 11 hits the World Trade Center at 8:46 (see 8:46 a.m. September 11, 2001). [Federal Aviation Administration, 10/14/2003, pp. 3-10 pdf file] If these accounts are correct, it means someone at NORAD should learn about Flight 77 when it deviates from its course (see (8:54 a.m.) September 11, 2001). However, the 9/11 Commission will later claim that the FAA teleconference is established about 30 minutes later (see (9:20 a.m.) September 11, 2001). The Air Force liaison to the FAA will claim she only joins it after the Pentagon is hit (see (Shortly After 9:37 a.m.) September 11, 2001).

The US Air Force liaison to the FAA arrives at FAA headquarters in Washington, DC, but, according to her own later recollections, does not immediately join a teleconference that has been set up in response to the first plane hitting the World Trade Center. [9/11 Commission, 5/23/2003; US Department of Transportation, 8/31/2006 pdf file]
Military Liaisons at FAA Headquarters - Each of the four military services within the US Department of Defense (the Army, the Navy, the Air Force, and the Marine Corps) assigns an FAA liaison officer to represent its requirements to the director of air traffic. These four liaisons share office space on the fourth floor of FAA headquarters. [Federal Aviation Administration, 3/21/2002 pdf file] Colonel Sheryl Atkins is the Air Force liaison there. Air Force liaisons at the FAA regional offices all report to Atkins, and she reports to the Pentagon.
Atkins Arrives at FAA Headquarters - Atkins will later recall that she was on her way to work when the first plane hit the WTC at 8:46 a.m., and she arrives at FAA headquarters “probably five, 10 minutes after that.” Once there, she goes to her office, where everyone is gathered around the television. She will see the CNN coverage of the second plane hitting the WTC at 9:03 a.m., and then immediately begin “personnel accounting.” [9/11 Commission, 3/26/2004; US Department of Transportation, 8/31/2006 pdf file]
Atkins Does Not Join Teleconference - According to a 2003 statement provided by the FAA, the FAA established a teleconference with several other agencies minutes after the first WTC tower was hit (see (8:50 a.m.) September 11, 2001), and the Air Force liaison to the FAA (i.e. Atkins) “immediately” joined this. [9/11 Commission, 5/23/2003] However, Atkins will say she only joins this teleconference after 9:37 a.m., when the Pentagon attack occurs (see (Shortly After 9:37 a.m.) September 11, 2001). [9/11 Commission, 3/26/2004; US Department of Transportation, 8/31/2006 pdf file]
Not Responsible for Reporting Hijackings - Atkins will tell the 9/11 Commission that she is not responsible for being a channel from the FAA to the military for hijack and/or fighter escort protocols. She will explain that her office is “a liaison military administrative office,” and therefore, if she is notified of a hijacking, this does not represent “procedural military notification.” 9/11 Commission staff members will confirm “that there is no indication in the FAA handbook for special military procedures that [Atkins’s] office has a role in the notification to the military of a hijack, or the request to the military for fighter asset support.” Atkins will recall that, on this morning, “no one at the FAA” says to her that she should initiate “notification for a military response and/or coordination with the FAA response to the attacks.” Instead, she is “involved with military administrative coordinating and facilitating… and not with direct assessment or response to the attacks.” [9/11 Commission, 3/26/2004; 9/11 Commission, 4/19/2004]
No Other Military Liaisons Present - The three other military liaisons that share office space with Atkins at FAA headquarters are currently elsewhere, spread out around northern Virginia and Washington, DC. The Navy and Marine Corps liaisons will arrive at FAA headquarters at around 10:30 a.m.; the Army liaison will not arrive until the following day.

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.

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]

Lieutenant Colonel Timothy Duffy, one of the two fighter pilots who took off in response to the hijacked Flight 11, contacts NORAD’s Northeast Air Defense Sector (NEADS) to request information on his target, but apparently neither Duffy nor the person he speaks with at NEADS mention that Flight 11 has already hit the World Trade Center during the call, even though both men should already be aware of the crash. [Federal Aviation Administration, 9/11/2001; Filson, 10/22/2002; Filson, 2003, pp. 60; 9/11 Commission, 1/7/2004 pdf file] Duffy and another pilot, Major Daniel Nash, took off from Otis Air National Guard Base at 8:46 a.m. (see 8:46 a.m. September 11, 2001), but they 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] Duffy has just spoken to an air traffic controller at the FAA’s Boston Center (see 8:54 a.m.-8:55 a.m. September 11, 2001) and ended the call saying he would talk to NEADS “right now.” [Federal Aviation Administration, 9/11/2001] Duffy will later recall that he contacts NEADS at about 8:56 a.m. or 8:57 a.m. [9/11 Commission, 1/7/2004 pdf file]
Duffy Told His Target Is over JFK Airport - Duffy presumably talks with Steve Hedrick at NEADS, since Hedrick is responsible for controlling the two Otis fighters. [9/11 Commission, 10/27/2003 pdf file] As soon as he has checked in with NEADS, Duffy will recall, “I authenticate to make sure I’ve got the right person.” He then asks for “bogey dope,” meaning information on his target—Flight 11—“to try to find out where the contact is.” [Filson, 10/22/2002; Filson, 2003, pp. 60] Duffy is told, incorrectly, that his target is over New York’s JFK International Airport. Duffy replies, “Okay, I know where that is,” and then, he will recall, “we started heading right down to Long Island.” [Aviation Week and Space Technology, 6/3/2002; ABC News, 9/11/2002]
WTC Crash Apparently Not Discussed - However, it appears that neither Duffy nor the person he speaks with at NEADS mention the plane crash at the WTC during their conversation. Duffy will say that when he is subsequently informed that a second plane has hit the WTC (see (9:03 a.m.) September 11, 2001 and 9:06 a.m.-9:07 a.m. September 11, 2001), he is unaware that Flight 11 has already hit the WTC. [ABC News, 9/11/2002; Filson, 10/22/2002; 9/11 Commission, 1/7/2004 pdf file] And yet Duffy and personnel at NEADS have already been informed of that first crash.
Pilot and NEADS Previously Notified of Crash - Duffy has just been told of the crash during his conversation with the Boston Center controller (see 8:55 a.m. September 11, 2001). [Federal Aviation Administration, 9/11/2001] NEADS personnel learned of it at 8:51 a.m. (see 8:51 a.m. September 11, 2001), although there is now some confusion on the NEADS operations floor over whether the plane that crashed was indeed Flight 11 (see 8:55 a.m.-8:57 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20; Vanity Fair, 8/1/2006] It will later be impossible to ascertain exactly what is said in the current conversation between Duffy and NEADS. Although tape recorders should be recording every radio channel at NEADS, because of a “technical issue,” the positions of Hedrick and his weapons director technician, Bradley Gardner, are supposedly not recorded (see (8:30 a.m.-3:00 p.m.) September 11, 2001). [9/11 Commission, 5/25/2004; 9/11 Commission, 7/24/2004, pp. 459; Vanity Fair, 8/1/2006]
Duffy Searches for Flight 11 on Radar Scope - Duffy will recall that following the call with NEADS, he is looking at his radar scope “to try and find a radar contact over the Kennedy sector with the hijacked aircraft.” Duffy will again contact NEADS to request “bogey dope” a few minutes later, and during that call is informed of the second plane hitting the WTC.

The jet fuel that spilled from Flight 11 when it hit the North Tower (see 8:46 a.m. September 11, 2001) has mostly burned up by this time. The National Institute of Standards and Technology (NIST), which 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 11, a Boeing 767, had a fuel capacity of 23,980 gallons, but was only carrying about 10,000 gallons when it hit the WTC. NIST will estimate that less than 1,500 gallons were consumed in a fireball inside the tower and a comparable amount was consumed in the fireballs outside the building. Therefore, approximately 7,000 gallons 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 have fewer combustibles than some 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 reaches a temperature above 600°C (see August 27, 2003). Although 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. 20, 29, 24, 77] The jet fuel will also burn up in the South Tower about 10 minutes after it is hit (see 9:13 a.m. September 11, 2001).

Anthony Whitaker.Anthony Whitaker. [Source: ABC News]Sergeant Alan DeVona, an officer with the Port Authority Police Department (PAPD), calls for the evacuation of the Twin Towers over a PAPD radio channel, and his colleague, Captain Anthony Whitaker, then calls for the evacuation of the entire World Trade Center complex, but their orders are apparently not passed on [Port Authority of New York and New Jersey, 11/12/2001, pp. 19 pdf file; 9/11 Commission, 5/18/2004 pdf file; Dwyer and Flynn, 2005, pp. 78-79; National Institute of Standards and Technology, 9/2005, pp. 200-202] DeVona, the PAPD patrol sergeant at the WTC, is currently in the lobby of the North Tower, coordinating with emergency agencies as they arrive there. [Devona, 3/28/2002, pp. 24 pdf file] Whitaker, the PAPD commanding officer at the WTC, is outside the Twin Towers, looking up at the burning North Tower. [Fink and Mathias, 2002, pp. 25; Murphy, 2002, pp. 184]
Officers Request Evacuation of the WTC - At 8:59 a.m., DeVona calls for the evacuation of the Twin Towers. “As soon as we’re able,” he says over the PAPD radio channel, “I want to start a building evacuation, Building 1 [i.e. the North Tower] and Building 2 [i.e. the South Tower], till we find out what caused this.” Immediately after DeVona says this, at 9:00 a.m., Whitaker makes a similar request over the same radio channel. “Let’s begin an evacuation of the entire complex,” he says. “All buildings, copy?” [Port Authority of New York and New Jersey, 11/12/2001, pp. 19 pdf file; National Institute of Standards and Technology, 9/2005, pp. 200-201] Unlike DeVona, Whitaker is ordering the evacuation of not just the Twin Towers, “but also the five other buildings throughout the 16-acre complex—the mercantile exchange, offices of major investment banking concerns, and government agencies, including the FBI, the Secret Service, and the CIA,” according to New York Times reporters Jim Dwyer and Kevin Flynn. [Dwyer and Flynn, 2005, pp. 79] Whitaker has decided to evacuate the WTC complex “because of the danger posed by highly flammable jet fuel from Flight 11,” which crashed into the North Tower at 8:46 a.m. (see 8:46 a.m. September 11, 2001), and “because of the magnitude of the calamity in the North Tower,” according to the 9/11 Commission. [9/11 Commission, 5/18/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 293]
Request Is the Second Time Evacuation Is Called For - Whitaker will later say that his current request is the “second time” he has called for the evacuation of the WTC complex. He will recall making his previous request—for “a full-scale evacuation of the entire complex”—shortly after Flight 11 crashed. [Fink and Mathias, 2002, pp. 23-25; Murphy, 2002, pp. 180-181, 184-185] Transcripts of PAPD radio transmissions will show that an evacuation was requested at 8:49 a.m., but only for the upper floors of the North Tower (see 8:49 a.m. September 11, 2001). [Port Authority of New York and New Jersey, 9/11/2001 pdf file; National Institute of Standards and Technology, 9/2005, pp. 195] And according to some accounts, that request was made by DeVona, not Whitaker.

Officer Repeats Order, for the Written Record - At 9:01 a.m., an officer at the PAPD desk in Building 5 of the WTC asks if they should evacuate their building. DeVona instructs the officer to wait, saying, “Stand by on Building 5.” Whitaker then asks the officer at the PAPD desk if they have started a “chrono log” yet. [Port Authority of New York and New Jersey, 11/12/2001, pp. 19 pdf file; National Institute of Standards and Technology, 9/2005, pp. 201] A “chrono” is a written record of what the PAPD is doing. [Murphy, 2002, pp. 182] The officer replies, “That’s affirmative.” At 9:02 a.m., Whitaker repeats his previous instruction, apparently to make sure it is officially recorded. He says: “For the chrono, evacuate all buildings in the complex. You copy? All building in the complex.” The officer at the PAPD desk acknowledges the instruction and then radios all PAPD units in the field, and tells them to evacuate “all tenants in the buildings… at the Trade Center.” [Port Authority of New York and New Jersey, 9/11/2001 pdf file; Port Authority of New York and New Jersey, 11/12/2001, pp. 19 pdf file; National Institute of Standards and Technology, 9/2005, pp. 202]
Orders Not Passed on to Other Agencies - It is unclear whether DeVona and Whitaker’s orders to evacuate the WTC are passed on. Their orders are given over PAPD radio channel W, which cannot be heard by the deputy fire safety directors in the Twin Towers, who are able to make announcements over the buildings’ public address systems. [WTC News, 8/1995 pdf file; 9/11 Commission, 7/24/2004, pp. 293; National Institute of Standards and Technology, 9/2005, pp. 200-202] According to the 9/11 Commission, there is “no evidence” that the orders are “communicated to officers in other Port Authority Police commands or to members of other responding agencies.” [9/11 Commission, 5/18/2004 pdf file] Despite this, an announcement is made over the public address system in the South Tower, advising workers to evacuate, at 9:02 a.m. (see 9:02 a.m. September 11, 2001). Attempts to order workers to evacuate the North Tower are unsuccessful because that building’s public address system was damaged by the plane crash (see (Between 8:47 a.m. and 8:55 a.m.) September 11, 2001).

A KC-135 tanker plane from Bangor, Maine, is flying south for a training mission at the time the terrorist attacks begin. The aircraft, which has the call sign “Maine 92,” is one of the eight KC-135s that are attached to the 101st Air Refueling Wing, based at Bangor International Airport. It is “heading south and was off the coast of North Carolina on the morning of 9/11,” the Bangor Daily News will later report. Details of the training mission it is involved with are unknown. The KC-135 will have already turned toward home and be heading north back to Bangor when the FAA “began shutting down all of the country’s airports and ordering planes to land,” according to the Bangor Daily News. [North American Aerospace Defense Command, 9/11/2001; Portland Press Herald, 9/13/2001; Bangor Daily News, 9/9/2011] (This is presumably a reference to the FAA’s 9:45 a.m. order that all airborne aircraft must land at the nearest airport (see (9:45 a.m.) September 11, 2001). [US Congress. House. Committee On Transportation And Infrastructure, 9/21/2001; 9/11 Commission, 7/24/2004, pp. 29] ) The KC-135’s crew members will contact NORAD’s Northeast Air Defense Sector (NEADS) and offer their assistance. The aircraft, which is carrying about 22,000 gallons of fuel, will then be sent to New Jersey to refuel a KC-10 tanker plane that is providing fuel to fighter jets patrolling the Eastern Seaboard. Another of the 101st Air Refueling Wing’s KC-135s, with the call sign “Maine 85,” is also airborne at the time of the terrorist attacks, on its way to a training mission off the coast of Long Island, New York (see 9:04 a.m.-9:06 a.m. September 11, 2001).

Colin Scoggins, the military liaison at the FAA’s Boston Center, learns from an FAA teleconference that there is a second hijacked plane over the US. He has previously called the FAA’s New York Center and was told, “We’re working a hijack,” but mistakenly thought the controller was referring to Flight 11 (see (Between 8:40 a.m. and 8:54 a.m.) September 11, 2001). According to author Lynn Spencer, Scoggins now hears on the FAA headquarters’ hijack teleconference of the second hijacked airliner, Flight 175. [Spencer, 2008, pp. 48-49 and 82] Spencer’s account is consistent with a May 2003 statement by the FAA, according to which the FAA established its teleconference “[w]ithin minutes after the first aircraft hit the World Trade Center” (see (8:50 a.m.) September 11, 2001). [9/11 Commission, 5/23/2003] But the 9/11 Commission will claim that the FAA headquarters’ hijacking teleconference is only established at “about 9:20” (see (9:20 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 36] According to Spencer, Scoggins assumes that NORAD’s Northeast Air Defense Sector (NEADS) is also on the FAA teleconference and is receiving the same information that he is about the second hijacking. However, the “FAA headquarters’ teleconference is between air traffic control facilities, the [FAA] Command Center, the Defense Department, and several other agencies; NORAD is not looped in.” [Spencer, 2008, pp. 82] Although the FAA will claim that the “Air Force liaison to the FAA immediately joined the FAA headquarters [teleconference] and established contact with NORAD on a separate line,” the Air Force liaison will subsequently claim she only joins the teleconference after 9:37 a.m., when the Pentagon is hit (see (Shortly After 9:37 a.m.) September 11, 2001). [9/11 Commission, 5/23/2003; US Department of Transportation, 8/31/2006 pdf file] Even though Scoggins assumes NEADS is already aware of the information, he will subsequently call it with the news of the second hijacking (see (9:02 a.m.-9:07 a.m.) September 11, 2001).

An air traffic controller at the FAA’s Indianapolis Center contacts the American Airlines dispatch office in Texas, and informs dispatcher Jim McDonnell that the center is unable to make contact with Flight 77 and does not know the location of this aircraft. The same controller called American Airlines and spoke with McDonnell four minutes earlier, reporting that radio contact had been lost with Flight 77 (see 8:58 a.m. September 11, 2001). McDonnell now says he has tried contacting Flight 77 but did not get a reply back. The controller then tells him: “We, uh, we lost track control of the guy. He’s in coast track but we haven’t, we don’t [know] where his target is and we can’t get a hold of him. Um, you guys tried him and no response?” McDonnell confirms, “No response.” The controller continues: “Yeah, we have no radar contact and, uh, no communications with him. So if you guys could try again.” McDonnell replies, “We’re doing it.” [New York Times, 10/16/2001; 9/11 Commission, 8/26/2004, pp. 30] Flight 77 made its last radio communication with controllers at 8:51 (see 8:51 a.m. September 11, 2001), and deviated from its assigned course at 8:54 (see (8:54 a.m.) September 11, 2001).

At the FAA’s Command Center in Herndon, Virginia, manager John White learns of the communication apparently made by a hijacker on Flight 11, stating “We have some planes” (see 8:24 a.m. September 11, 2001), and quickly notifies the national operations manager of this. Terry Biggio, the operations manager at the FAA’s Boston Center, is relaying all the information he has about Flight 11 to the Command Center’s teleconference. In the conference room at the Command Center, White is listening in. [Spencer, 2008, pp. 79-80] Because the air traffic controller monitoring Flight 11 had not understood the “We have some planes” hijacker communication, the Boston Center’s quality assurance specialist had been instructed to “pull the tape” of the transmission, listen to it carefully, and then report back. [9/11 Commission, 7/24/2004, pp. 19] Having learned that the specialist has deciphered the transmission, Biggio now relays the details of it over the teleconference. Seconds later, those at the Command Center see Flight 175 crashing into the South Tower of the World Trade live on CNN. White promptly dispatches a manager to pass on the details of the transmission to Ben Sliney, the national operations manager at the Command Center (see 9:06 a.m. and After September 11, 2001).

Brian Meenan.Brian Meenan. [Source: US Air Force]The Air Traffic Services Cell (ATSC)—a small office at the FAA’s Command Center in Herndon, Virginia, manned by military reservists—is activated.
Officers Learn of Attacks - Three officers are currently on duty in the ATSC: Colonel John Czabaranek, Lieutenant Colonel Michael-Anne Cherry, and Major Kevin Bridges. Colonel Brian Meenan, the director of the cell, is not in the ATSC at this time, and so Czabaranek, his deputy, is currently in charge. Czabaranek, Cherry, and Bridges learned of the first attack in New York at around 8:55 a.m. when another employee at the Command Center told them to turn on CNN, because an aircraft had crashed into the World Trade Center. The three officers initially thought the crash was an accident, but realized it was not when they saw the second aircraft hitting the WTC at 9:03 a.m. They then established contact with the Air Force Ops Center.
Cell Activated, Though Timing Unclear - The ATSC is activated, although the exact time this happens at is unclear. According to Aviation Week and Space Technology magazine, the cell “quickly became a key communications node during the military’s response to [the] terrorist attacks.” [US Air Force, 9/11/2001; Aviation Week and Space Technology, 6/10/2002] Jeff Griffith, the FAA’s deputy director of air traffic control, will tell the 9/11 Commission that “the military officers assigned to the Air Traffic Services Cell became immediately involved in coordinating FAA… Command Center actions with military elements.” [9/11 Commission, 6/9/2004 pdf file] According to a chronology of the ATSC’s actions on this day, calls to activate the cell are apparently made at unspecified times following the second attack in New York and before the FAA’s ground stop (at 9:26 a.m.). These calls are made by a Lieutenant Colonel Mahoney and a Colonel Litzenberger from the Air Force Ops Center. Apparently shortly after the calls are made, Czabaranek contacts NORAD to let it know that the ATSC is “up and running.” [US Air Force, 9/11/2001]
Military Cell Aided by Recently-Installed Hardware - The ATSC’s response to the terrorist attacks benefits from the fact that, six weeks earlier, the cell had a secure terminal to access the SIPRNET—the military’s classified version of the Internet—installed, along with other hardware, which significantly enhances the movement of vital information. According to Meenan, because the cell has the SIPRNET terminal, “we could immediately look at NORAD and [Defense Department] plans as they evolved; filter, package, and format them, then walk out to the [FAA] national operations manager—who had control of the entire national airspace system—and give him current visibility into… fighter, tanker, and support aircraft activities. It cut down our response time tremendously.” [Aviation Week and Space Technology, 6/10/2002]
ATSC Is a Bridge between FAA and Military - The ATSC is a “part-time military outfit, staffed by part-time Air Force Reserve members” who “provide a bridge between the civilian and military worlds when air traffic issues arise,” according to the Air Force Times. For example, “During a crisis, the armed forces suddenly may need to inject a large number of military airplanes into a sky that typically handles only a few hundred.” [Air Force Times, 2000] However, Czabaranek will tell the 9/11 Commission that the ATSC is “not part of [the] FAA/NORAD hijack notification process.” [9/11 Commission, 4/14/2004]
Presence of ATSC Officers a 'Fluke' - According to Aviation Week and Space Technology, the presence of the three ATSC officers at the FAA Command Center this morning is a “fluke,” since the Pentagon staffs the military cell “only three days per month for refresher training, but September 11 happened to be one of those days.” [Aviation Week and Space Technology, 12/17/2001]
Cell Handles Aircraft after Airspace Shut Down - Later in the day, after the national airspace has been shut down (see (9:45 a.m.) September 11, 2001), the ATSC personnel will coordinate actions relating to military and other special flights that are permitted to fly. [9/11 Commission, 2003] They will be responsible for validating the requests they receive for the movement of aircraft, and issuing permissions in response to those requests.

Bruce Barrett.Bruce Barrett. [Source: H. Darr Beiser / USA Today]The FAA’s New York Center declares “air traffic control zero” (“ATC zero”), which means that all air traffic is prevented from departing from, arriving at, or traveling through the center’s airspace until further notice. [USA Today, 8/12/2002; Freni, 2003, pp. 18; 9/11 Commission, 8/26/2004, pp. 24] According to author Lynn Spencer: “ATC zero is designed for situations in which an air traffic facility is completely incapable of handling aircraft due to a massive computer failure, power outage, or even a large enough weather system. The declaration pushes all their aircraft onto neighboring sectors, and any new airplanes from adjacent sectors are turned back, at the sector boundaries if necessary.” [Spencer, 2008, pp. 68] The decision to declare ATC zero is made after the second plane hits the World Trade Center, confirming that the US is under terrorist attack. There are currently hundreds of aircraft in the skies around New York and the western Atlantic that the New York Center is responsible for. [Associated Press, 8/12/2002] Bruce Barrett, a senior manager at the New York Center, announces, “We’re declaring ATC zero,” and Mike McCormick, the center’s air traffic control manager, approves the order. Several of the managers there then start informing air traffic controllers of the decision.
Unprecedented Order - USA Today will report that this decision is unprecedented: “Controllers had gone to ‘air traffic control zero’ before, but only when their radar shut down or their radio transmitters went silent. The planes kept flying then, and controllers in other centers guided them. This time, ATC zero means something far more drastic. It means emptying the skies—something that has never been attempted. And not just the skies over Manhattan. Controllers must clear the air from southern New England to Maryland, from Long Island to central Pennsylvania—every mile of the region they control.… Controllers from Cleveland to Corpus Christi must reroute jets headed to the region and put some in holding patterns.”
Accounts Conflict over Whether Center Seeks Permission - According to USA Today, McCormick and Barrett declare ATC zero without first seeking permission from higher-ups, because a “call to Washington could take minutes, and they aren’t sure they have that long.” [USA Today, 8/12/2002] But according to Lynn Spencer, a New York Center supervisor has already requested ATC zero in a call to the FAA’s Herndon Command Center. Ben Sliney, the Command Center’s national operations manager, assured the supervisor, “You take care of matters in your center and we will provide all the assistance necessary by stopping any further aircraft from entering your airspace.” [Spencer, 2008, pp. 68]

At the FAA’s Herndon Command Center, national operations manager Ben Sliney responds to the second plane hitting the World Trade Center and orders a “first-tier ground stop” to prevent aircraft from departing, arriving at, or flying through the airspace of the FAA’s New York Center. Like many others at the Command Center, Sliney has just seen Flight 175 crashing into the South Tower of the WTC live on CNN. A manager at the center then reports to him the news just received over the Command Center’s teleconference, about the sinister radio transmissions that have been deciphered by the Boston Center, stating “We have some planes” (see 9:03 a.m. September 11, 2001). According to author Lynn Spencer, “The words take on a sickening significance” to Sliney “after what he has just observed.”
Sliney Orders 'First-Tier Ground Stop' - Sliney orders across the room, “Give me a first-tier ground stop!” According to Spencer, “The order stops all aircraft departing, arriving, or flying through New York Center’s airspace, effectively closing down the nation’s busiest skies.” At 9:06 a.m., an advisory is sent out to every air traffic control facility in the nation, and the skies above New York are now officially closed. Numerous flights that are in the air or preparing to take off are given “holding instructions.” Meanwhile, the large screen at the front of the room in the Command Center displays the footage of Flight 175 hitting the WTC as it is shown repeatedly on CNN. According to Spencer: “[I]t becomes sickeningly obvious to all watching that the plane was a large commercial airliner. And it was no accident.” [AOPA Pilot, 11/2001; Spencer, 2008, pp. 80-81] Around this same time, the FAA’s New York Center takes action similar to that of the Command Center, declaring “air traffic control zero,” which prevents all air traffic from departing, arriving at, or traveling through its airspace (see 9:05 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 24] And at around 9:25 a.m., the Command Center will order a “nationwide ground stop,” which prevents any aircraft from taking off in the entire United States (see (9:26 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 33]
Sliney Expands Teleconference - Also in response to the second WTC crash, Sliney decides that he needs to expand the Command Center’s teleconference (see (Between 8:48 a.m. and 9:00 a.m.) September 11, 2001) so as to include the secretary of transportation. [Spencer, 2008, pp. 81] It is expanded to include the secretary of transportation’s office, FAA headquarters, and other agencies. [Aviation Week and Space Technology, 12/17/2001] It is unclear whether Transportation Secretary Norman Mineta participates himself, as he is told to go to the White House around this time, and subsequently heads there (see (9:15 a.m.) September 11, 2001). [9/11 Commission, 5/23/2003]
Military Liaison Unable to Help - Sliney also seeks out the military liaison at the Command Center to get more information about what is going on. [Spencer, 2008, pp. 81] Presumably this officer is one of the three members of the Air Traffic Services Cell (ATSC) there (see (Between 9:04 a.m. and 9:25 a.m.) September 11, 2001). [Aviation Week and Space Technology, 12/17/2001; Aviation Week and Space Technology, 6/10/2002] But, according to Spencer, it is “clear that the lieutenant colonel’s job has nothing to do with NORAD or the air defense interceptors. He is military, but his job duties at the Command Center are focused on military airspace usage. He has no place in the military chain of command that is relevant this morning.” Sliney therefore “can only assume that people much higher up than both of them are dealing with the military response. The fighters must be on their way.” [Spencer, 2008, pp. 81]

Booker Elementary School in Sarasota, Florida, and listens to the students reading a story about a pet goat for five minutes, despite having just been told that the nation is under attack. [Wall Street Journal, 3/22/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 38-39] Bush has been in the classroom since 9:02 a.m., listening to 16 second graders demonstrating their reading skills (see 9:02 a.m. September 11, 2001). [Associated Press, 8/25/2002; Washington Times, 10/8/2002] Andrew Card, his chief of staff, has just come into the room, and told him a second plane has crashed into the World Trade Center and America is under attack (see (9:07 a.m.) September 11, 2001). The teacher, Sandra Kay Daniels, now continues the reading demonstration, instructing the children: “At the count of three. Everyone should be on page 163.” The children then read a story called The Pet Goat, which is about a girl’s pet goat that protects the family home from a burglar. [Sammon, 2002, pp. 83-85; Washington Times, 10/7/2002; Editor & Publisher, 7/2/2004; Wall Street Journal, 7/2/2004] Despite having just heard that the nation is under attack, Bush picks up his copy of the textbook and tries to follow along as the children read. [Tampa Tribune, 9/1/2002; Washington Times, 10/7/2002] He will later explain why he stays where he is and listens to the rest of the reading demonstration, rather than leaving the classroom to go and respond to the attacks, writing: “I knew my reaction would be recorded and beamed throughout the world. The nation would be in shock; the president could not be. If I stormed out hastily, it would scare the children and send ripples of panic throughout the country.” [Bush, 2010, pp. 127]
Bush Remains Composed - Bush is in fact surprisingly calm for the rest of the reading demonstration. He “maintained his composure and sent an image of calm to the nation,” White House press secretary Ari Fleischer, who is in the classroom at this time, will comment. [Fleischer, 2005, pp. 140] “He didn’t change his facial expression; he didn’t show what obviously had to be nothing but alarm and concern,” Fleischer will say. [White House, 8/8/2002] “It was pretty amazing to me how he could not show any sign of panic,” White House photographer Eric Draper, who is also in the classroom, will comment. [Albuquerque Tribune, 9/10/2002] A video recording of the event will show that Bush listens to the children reading The Pet Goat for five minutes. Finally, the children read the last line of the story, saying aloud, “More—to—come.” But even then, Bush will stay in the classroom for at least two more minutes, asking the children questions and talking briefly with the school’s principal (see (9:13 a.m.-9:15 a.m.) September 11, 2001).

[Code One Magazine, 1/2002; Newhouse News Service, 3/31/2005; Politico Magazine, 9/9/2016] There are “multiple erroneous reports of hijacked aircraft” during the morning, according to the 9/11 Commission Report. [9/11 Commission, 7/24/2004, pp. 28] At around 9:09 a.m., the FAA Command Center reports that 11 aircraft are either not communicating with FAA facilities or flying unexpected routes. [Aviation Week and Space Technology, 6/3/2002] Major General Larry Arnold, the commander of the Continental United States NORAD Region, will later claim that during the “four-hour ordeal” of the attacks, a total of 21 planes are identified as possible hijackings. [Filson, 2002; Code One Magazine, 1/2002; Filson, 2003, pp. 71] Colonel Robert Marr, the battle commander at NORAD’s Northeast Air Defense Sector (NEADS), will say, “At one time I was told that across the nation there were some 29 different reports of hijackings.” [Newhouse News Service, 3/31/2005] Secret Service agent Dave Wilkinson, who travels with President Bush on Air Force One after it leaves Sarasota, Florida (see 9:54 a.m. September 11, 2001), will recall that by the time the plane reaches Offutt Air Force Base in Nebraska, at 2:50 p.m. (see 2:50 p.m. September 11, 2001), “there were like 15 to 20 planes still unaccounted for” nationwide. “For everything we knew, they were all hijacked,” he will say. [Politico Magazine, 9/9/2016] Officials will claim that these false reports cause considerable confusion. Arnold will recall that particularly during the time between the Pentagon being hit at, 9:37 a.m., and Flight 93 going down, at around 10:03 a.m., “a number of aircraft are being called possibly hijacked.… There was a lot of confusion, as you can imagine.” [Filson, 2003, pp. 71-73] He will say: “We were receiving many reports of hijacked aircraft. When we received those calls, we might not know from where the aircraft had departed. We also didn’t know the location of the airplane.” [Code One Magazine, 1/2002] Marr will comment: “There were a number of false reports out there. What was valid? What was a guess? We just didn’t know.” [Filson, 2003, pp. 73] Assistant Secretary of Defense for Public Affairs Victoria Clarke, who is in the Pentagon during the attacks and for most of the rest of the day, will recall: “There were lots of false signals out there. There were false hijack squawks, and a great part of the challenge was sorting through what was a legitimate threat and what wasn’t.” [CNN, 6/17/2004; Clarke, 2006, pp. 215-231]

Command Center Calls Field Facilities - Sliney wants air traffic control facilities to notify him of anything out of the ordinary, such as a radar target disappearing from the radar scope, loss of communication with an aircraft, or an aircraft making an unauthorized change of course. He also wants to know immediately of any glitches that occur, even if these are common, everyday problems, such as a flight deviating from its course, missing a frequency change, overlooking a radio call, or getting a transponder code wrong. The center’s controllers at each regional desk therefore start calling their field facilities, and ask them to report any unusual occurrences. [9/11 Commission, 7/22/2003 pdf file; Spencer, 2008, pp. 125] The Command Center has telecommunications lines to all the major air traffic control facilities in the US, which enables it to reach out to those facilities and establish the big picture about aircraft activity. [Freni, 2003, pp. 64]
'More and More' Responses Received - Following the call for information, numerous reports of suspicious activity are received from the air traffic control facilities. [Spencer, 2008, pp. 125-126] Linda Schuessler, the deputy director of system operations at the Command Center, will later recall, “[W]e started getting more and more calls about bomb threats, about aircraft that we had lost communication or radar identification with.” [Aviation Week and Space Technology, 12/17/2001]
Center Lists Suspect Aircraft - Sliney wants a list compiled of the reportedly suspicious aircraft. A dry-erase board is set up in the middle of the room. On it a manager keeps track of the reports that are coming in, writing down where each suspect aircraft was last seen, who was working it, where the flight originated, and where it is going. Another person contacts the field facilities to follow up on the reports. [9/11 Commission, 7/22/2003 pdf file; Spencer, 2008, pp. 126]
Two Dozen Suspicious Flights - Author Pamela Freni will later describe, “[F]or the next several hours the call signs and status” of every suspicious aircraft will be recorded. Command Center personnel call “airline operations centers, trying to determine any crises on each flight. Only when each plane landed or was found safe did its identification information disappear from the board. Upward to two dozen were listed at one time, but ultimately the number was whittled to 11 highly suspicious cases” (see (9:09 a.m. and After) September 11, 2001). “Nine of those airplanes would land safely. Two of them—AA 77 and UA 93—would not.” [Freni, 2003, pp. 64-65]

Tape recordings of the operations floor at NORAD’s Northeast Air Defense Sector (NEADS) in Rome, New York indicate that both NEADS and NORAD are experiencing significant problems communicating with other agencies:
bullet At 9:12 a.m., a member of staff at NEADS tells another military agency over the phone: “We’re trying to reach the military coordinator. We’re having a difficult time.” [North American Aerospace Defense Command, 9/11/2001]
bullet At 9:22 a.m., a women at NEADS calls what is apparently an American Airlines office in New York, to ask about a report NEADS has received that Flight 11 is still airborne and headed towards Washington (see 9:21 a.m. September 11, 2001). After being given a phone number she needs to call for more information, the woman at NEADS replies: “[D]o me a favor and have them call us? We cannot call out for some reason.” [North American Aerospace Defense Command, 9/11/2001]
bullet At around 10:31 a.m., someone from the 1st Fighter Wing, which is the host unit at Langley Air Force Base in Virginia, calls NEADS. During the conversation, they mention, “I tried to get a hold of NORAD… and their lines are all busy.” NEADS replies, “Yeah, I can believe it,” and adds, “Right now the circuits are so busy.” [North American Aerospace Defense Command, 9/11/2001]
bullet Around 11:50 a.m., someone with the New York Air National Guard’s 109th Airlift Wing is on the phone to NEADS. They mention, “We’re having a tough time getting hold of you guys.” NEADS responds, “We’re having problems with our phone lines as well.” [North American Aerospace Defense Command, 9/11/2001]
bullet At 11:57 a.m., a member of staff at NEADS complains: “They turned off all the goddamned lines to the outside.… No, local. So you can’t make outside phone calls.” [North American Aerospace Defense Command, 9/11/2001]

An air traffic controller at Washington’s Reagan National Airport struggles with an Arab-sounding private pilot who keeps veering into Washington airspace. [Spencer, 2008, pp. 144-145] Reagan National Airport is less than one mile from the Pentagon, and just a few miles from the White House and the Capitol building. [St. Petersburg Times, 10/3/2001] The airspace around it and much of Washington is designated class B airspace, which means no one is supposed to fly there without a working transponder and permission from an air traffic controller. [Washington Post, 9/12/2001] Eric Cole, a controller in Reagan Airport’s air traffic control tower, is continually being bothered by the pilot, who has an Arab accent and is flying a banner tow airplane. Cole repeatedly directs the pilot, “Go further south!” The pilot replies, “Okay, I’m going further south,” but does not do so. He keeps infringing the Washington airspace and asking to get closer to the city. Banner tow airplanes are almost unheard of in this area, and Cole cannot understand why the pilot is being so persistent, almost argumentative. Finally, Cole yells at him: “No, you’re not going further south! I can see that you’re not going further south!” Shortly after 9:06 a.m., the control tower receives the instruction to secure the airspace around Washington and turn away all non-airliner aircraft (see Shortly After 9:06 a.m. September 11, 2001). The controllers are then able to order the annoying banner tow pilot out of their airspace for good. [Spencer, 2008, pp. 144-145]

Transportation Secretary Norman Mineta, who saw the second plane hitting the WTC on television while at the Department of Transportation, had been called to the White House (see (8:48 a.m.-9:05 a.m.) September 11, 2001). When he arrives there, as he later recalls, he sees “People… coming out of the White House, pouring out of the Executive Office Building, running over towards Lafayette Park.” As he enters the White House, Mineta is told he has to be briefed by counterterrorism “tsar” Richard Clarke. He goes to the Situation Room where Clarke talks to him for four or five minutes, briefly informing him of what is going on. Clarke instructs him, “You have to get over to the Presidential Emergency Operation Center to be with the vice president.” The Presidential Emergency Operations Center (PEOC) is the bunker located below the White House. As Mineta does not know where it is, a Secret Service agent leads him to it. He will arrive there around 9:20-9:27, according to his own recollections (see (Between 9:20 a.m. and 9:27 a.m.) September 11, 2001).

The FAA’s New England regional office calls the FAA’s Herndon Command Center, and asks it to tell Cleveland Center to contact Delta Air Lines Flight 1989 and advise it to use extra cockpit security. The reason the New England regional office makes this request is unclear. [9/11 Commission, 7/24/2004, pp. 10] As the 9/11 Commission will describe, apparently in response to the request, “[A]t 9:19 the FAA… Command Center in Herndon ordered controllers to send a cockpit warning to Delta 1989 because, like American 11 and United 175, it was a transcontinental flight departing Boston’s Logan Airport.” [9/11 Commission, 7/24/2004, pp. 455] Minutes earlier, the FAA’s Boston Center asked the Command Center to contact the nation’s FAA centers and instruct them to tell all airborne aircraft to increase their cockpit security (see (9:15 a.m.) September 11, 2001). The Command Center’s instruction to air traffic controllers about Delta 1989 is apparently an exception, as the 9/11 Commission will say it found “no evidence to suggest that the Command Center acted on this request.” [9/11 Commission, 7/24/2004, pp. 23; 9/11 Commission, 8/26/2004, pp. 25-26] Delta 1989 will subsequently be mistakenly reported as having been hijacked (see (9:28 a.m.-9:33 a.m.) September 11, 2001 and 9:39 a.m. September 11, 2001).

The FAA sets up a hijacking teleconference with several agencies, including the Defense Department. This is almost one hour after the FAA’s Boston flight control began notifying the chain of command (see 8:25 a.m. September 11, 2001) and notified other flight control centers about the first hijacking at 8:25 a.m. (see 8:25 a.m. September 11, 2001). According to the Acting FAA Deputy Administrator Monte Belger, this teleconference (called the “hijack net”) is “the fundamental primary source of information between the FAA, [Defense Department], FBI, Secret Service, and… other agencies.” Yet even after the delay in setting it up, FAA and Defense Department participants later claim it plays no role in coordinating the response to the hijackings. The 9/11 Commission says, “The NMCC [National Military Command Center inside the Pentagon] officer who participated told us that the call was monitored only periodically because the information was sporadic, it was of little value, and there were other important tasks. The FAA manager of the teleconference also remembered that the military participated only briefly before the Pentagon was hit.” [9/11 Commission, 6/17/2004; 9/11 Commission, 7/24/2004, pp. 36] According to a statement provided by the FAA to the 9/11 Commission in 2003, this teleconference began significantly earlier—“[w]ithin minutes after the first aircraft hit the World Trade Center” (see (8:50 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]

Managers from American Airlines and United Airlines are added by the FAA to a teleconference, but they receive no guidance from top government officials on what to do. According to author Lynn Spencer, at some point after the second aircraft hit the World Trade Center, the executives from the two airlines are “quickly on the phone to FAA headquarters and the FAA Command Center.” They are brought into “a conference call that has now been set up with Secretary of Transportation Norman Mineta and Vice President Dick Cheney at the White House. The airline executives inform the secretary that they are each dealing with additional aircraft that they are unable to contact. They seek guidance, but there is none.… The nation is under attack, but there is no plan in place, and no guidance is forthcoming from the top as the crisis escalates.” [Spencer, 2008, pp. 109] The time when the airline executives join the teleconference is unclear. In Spencer’s account, she places it after United Airlines dispatchers have warned their aircraft to secure their cockpits (see (Shortly After 9:21 a.m.) September 11, 2001), which would mean some time after 9:21. [9/11 Commission, 8/26/2004, pp. 37; Spencer, 2008, pp. 109] But Spencer also says that, when the executives join the conference, the “president is still reading to children in a Florida school room” (see (9:08 a.m.-9:13 a.m.) September 11, 2001), which would be roughly between 9:05 and 9:15. [9/11 Commission, 7/24/2004, pp. 38-39; Spencer, 2008, pp. 109] If Norman Mineta is already participating in the teleconference when the airline executives join it, the time would have to be after around 9:20, which is when Mineta later says he arrived at the Presidential Emergency Operations Center (PEOC) below the White House (see (Between 9:20 a.m. and 9:27 a.m.) September 11, 2001). [9/11 Commission, 5/23/2003] And Cheney, who Spencer also says is participating in the teleconference when the executives join it, arrives at the PEOC as late as 9:58, according to the 9/11 Commission, although other accounts indicate he arrives there much earlier than this (see (Shortly After 9:03 a.m.) September 11, 2001). [ABC News, 9/14/2002; 9/11 Commission, 7/24/2004, pp. 40] According to the Wall Street Journal, American Airlines president Don Carty and United Airlines CEO Jim Goodwin are talking on the phone with Mineta (presumably over the conference call) about five minutes before the FAA shuts down all US airspace (see (9:45 a.m.) September 11, 2001), which would mean they are participating in the teleconference by around 9:40 a.m. [US Congress.

Major Brad Derrig.Major Brad Derrig. [Source: ABC]At Langley Air Force Base in Virginia, the pilots of three F-16s receive the order to scramble (i.e. take off immediately). A Klaxon horn sounds and the status lights in the hangars change from yellow to green, notifying them of the order. [Longman, 2002, pp. 65; Filson, 2003, pp. 63; Spencer, 2008, pp. 141] The fighter jets belong to the North Dakota Air National Guard’s 119th Fighter Wing. The wing has a small detachment at Langley that serves as one of NORAD’s seven “alert” sites around the US, responsible for defending the nation against attack. [Spencer, 2008, pp. 114] The jets are already at “battle stations,” with the pilots in the cockpits but the engines off (see (9:09 a.m.) September 11, 2001). [Filson, 2003, pp. 55; 9/11 Commission, 7/24/2004, pp. 24; Spencer, 2008, pp. 117-119] The scramble order has just been issued by NORAD’s Northeast Air Defense Sector (NEADS) (see 9:24 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 16]
Third Pilot Launched - The unit at Langley keeps two F-16s on “alert”—armed, fueled, and ready to take off within minutes if called upon. [Air Force Magazine, 2/2002; Bergen Record, 12/5/2003; 9/11 Commission, 7/24/2004, pp. 17] But NEADS has instructed it to launch as many aircraft as it can (see (Between 9:10 a.m. and 9:23 a.m.) September 11, 2001), and so the unit’s operations manager Captain Craig Borgstrom is also preparing to take off in a third jet. [Spencer, 2008, pp. 118-119] Major Dean Eckmann calls the other two pilots, saying, “Quit check,” indicating a radio check. Major Brad Derrig responds, “Two.” Borgstrom replies: “Three. I’m going with you!” This is news to Derrig. According to author Lynn Spencer, Derrig is “stunned.… [N]ot much surprises him, but this does.” Borgstrom joining them as a pilot will mean that, in the middle of this unprecedented crisis, their unit will be left without a commanding officer. [Spencer, 2008, pp. 142]
Only Two Jets Fully Armed - The two jets that are kept on alert are fully armed. As Eckmann will later recall, “We can carry M9 heat seekers, Sidewinders for the M7 Sparrow, plus we have an internal 20 mm Vulcan cannon, and we were pretty much armed with all that.” [BBC, 9/1/2002] However, Borgstrom’s jet has guns only, and though the six-barrel 20 mm gun can fire 6,000 rounds per minute, it requires close range.
Pilot Unqualified to Lead Three Jets - As the three aircraft taxi out to the runway, Eckmann is concerned that he has not yet qualified as a mission commander—a “four-ship”—and is therefore not authorized to lead more than one fighter jet. He calls the other pilots, saying, “Hey, I’m only a two-ship!” But Derrig, who is a full-time instructor pilot for the Air National Guard, urges him not to worry. He responds: “Press! I’m an instructor,” giving his approval for the flight to operate as a “three-ship” under Eckmann’s lead. [Spencer, 2008, pp. 142] The three jets will take off and be airborne by 9:30 a.m. (see (9:25 a.m.-9:30 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 16]

Captain Craig Borgstrom.Captain Craig Borgstrom. [Source: US Air Force / Austin Knox]The three F-16 fighter jets ordered to scramble from Langley Air Force Base in Virginia (see 9:24 a.m. September 11, 2001) take off and, radar data will show, are airborne by 9:30 a.m. [North American Aerospace Defense Command, 9/18/2001; Christian Science Monitor, 4/16/2002; 9/11 Commission, 7/24/2004, pp. 27]
Delayed during Launch - Major Dean Eckmann will recall that, after receiving the scramble order, he and the two other pilots have “a pretty quick response time. I believe it was four to five minutes we were airborne from that point.” [BBC, 9/1/2002] According to the 1st Air Force’s book about 9/11, the three fighters are “given highest priority over all other air traffic at Langley Air Force Base” as they are launching. [Filson, 2003, pp. 63] But, according to author Lynn Spencer, in spite of this, the jets are delayed. As Eckmann is approaching the runway, he calls the control tower for clearance to take off, but the tower controller tells him, “Hold for an air traffic delay.” Air traffic controllers at the FAA’s Washington Center “have not had time to clear airliners out of the way for the northerly heading. Dozens of aircraft at various altitudes fill the jets’ route.” After having to wait two minutes, Eckmann complains: “We’re an active air scramble. We need to go now!” Finally, the tower controller tells him, “Roger, Quit flight is cleared for takeoff, 090 for 60,” meaning the fighters are to fly due east for 60 miles (see (9:30 a.m.) September 11, 2001).
Taking Off - The three jets launch 15 seconds apart, with Eckmann in front and the two other jets following. [Spencer, 2008, pp. 143-144] Pilot Craig Borgstrom will later recall, “[W]e took off, the three of us, and basically the formation we always brief on alert, we’ll stay in a two- to three-mile trail from the guy in front.” [Filson, 2003, pp. 63] According to the BBC, the pilots get a signal over their planes’ transponders, indicating an emergency wartime situation. [BBC, 9/1/2002]
Could Reach Washington before Pentagon Attack - F-16s have a maximum speed of 1,500 mph at high altitude, or 915 mph at sea level, so the three fighters could plausibly travel the 130 miles from Langley Air Force Base to Washington in just minutes. [Chant, 1987, pp. 404; Associated Press, 6/16/2000; USA Today, 9/16/2001; Washington Post, 9/16/2001 pdf file; US Air Force, 10/2007] Major General Larry Arnold, the commanding general of NORAD’s Continental US Region, will tell the 9/11 Commission, “I think if those aircraft had gotten airborne immediately, if we were operating under something other than peacetime rules, where they could have turned immediately toward Washington, DC, and gone into burner, it is physically possible that they could have gotten over Washington” before 9:37, when the Pentagon is hit. [9/11 Commission, 5/23/2003] Yet according to the 9/11 Commission, the jets are redirected east over the Atlantic Ocean and will be 150 miles from the Pentagon when it is hit (see 9:30 a.m.-9:37 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 27]
Conflicting Times - Some early news reports after 9/11 will say the Langley jets take off at the later time of 9:35 a.m. [Washington Post, 9/12/2001; CNN, 9/14/2001; Washington Post, 9/15/2001; CNN, 9/17/2001] But according to Colonel Alan Scott, the former vice commander of the Continental US NORAD Region, though the jets are airborne at 9:30, the report of this does not come down until 9:35, so this fact may account for the conflicting times.

FAA Administrator Jane Garvey.
FAA Administrator Jane Garvey. [Source: FAA]Time magazine later reports that Jane Garvey, head of the FAA, “almost certainly after getting an okay from the White House, initiate[s] a national ground stop, which forbids takeoffs and requires planes in the air to get down as soon as is reasonable. The order, which has never been implemented since flying was invented in 1903, applie[s] to virtually every single kind of machine that can takeoff—civilian, military, or law enforcement.” Military and law enforcement flights are allowed to resume at 10:31 a.m. (see 10:31 a.m. September 11, 2001) A limited number of military flights—the FAA will not reveal details—are allowed to fly during this ban. [Time, 9/14/2001] Garvey later calls it “a national ground stop… that prevented any aircraft from taking off.” [US Congress. House. Committee On Transportation And Infrastructure, 9/21/2001] Transportation Secretary Norman Mineta later says he was the one to give the order: “As soon as I was aware of the nature and scale of the attack, I called from the White House to order the air traffic system to land all aircraft, immediately and without exception.” [US Congress. Senate. Committee on Commerce, Science and Transportation, 9/20/2001] According to Mineta, “At approximately 9:45… I gave the FAA the final order for all civil aircraft to land at the nearest airport as soon as possible.” [9/11 Commission, 5/23/2003] At the time, 4,452 planes are flying in the continental US. A later account states that Ben Sliney, the FAA’s National Operations Manager, makes the decision without consulting his superiors, like Jane Garvey, first. It would be remarkable if Sliney was the one to make the decision, because 9/11 is Sliney’s first day on the job as National Operations Manager, “the chess master of the air traffic system.” [USA Today, 8/12/2002] When he accepted the job a couple of months earlier, he had asked, “What is the limit of my authority?” The man who had promoted him replied, “Unlimited.” [USA Today, 8/13/2002] Yet another account, by Linda Schuessler, manager of tactical operations at the FAA Command Center where Sliney was located, says, “… it was done collaboratively… All these decisions were corporate decisions. It wasn’t one person who said, ‘Yes, this has got to get done.’” [Aviation Week and Space Technology, 12/17/2001] About 500 planes land in the next 20 minutes, and then much more urgent orders to land are issued at 9:45 a.m. (see (9:45 a.m.) September 11, 2001).

[9/11 Commission, 5/23/2003; 9/11 Commission, 6/17/2003; 9/11 Commission, 2004] Why the Boston Center does this is unclear, since Delta 1989 is currently being handled by the FAA’s Cleveland Center, not the Boston Center.

[9/11 Commission, 7/24/2004, pp. 16, 28] Twelve minutes later, at 9:39, Boston Center will call NEADS and incorrectly tell it that Delta 1989 is a possible hijack (see 9:39 a.m. September 11, 2001).

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).

John Werth.John Werth. [Source: CBS]Shortly after hearing strange noises from the cockpit of Flight 93, Cleveland air traffic controllers notice the plane has descended about 700 feet. John Werth, the controller who is handling the plane, tells the supervisor nearest to him, “I think we have another one [i.e., another hijacking].” He will repeatedly radio the cockpit over the next four minutes, asking the pilot to confirm the hijacking, but receive no response. At 9:30 a.m., Werth begins asking other nearby flights on his frequency if they’ve heard screaming; several say that they have. [Gregor, 12/21/2001 pdf file; 9/11 Commission, 7/24/2004, pp. 28; CBS News, 9/10/2006] The Cleveland Center immediately notifies United Airlines’ headquarters of the loss of communication with Flight 93 (see (9:30 a.m.) September 11, 2001). However, the FAA chain of command is apparently not also immediately informed. And the Cleveland Center will not contact NORAD’s Northeast Air Defense Sector (NEADS) about Flight 93 until 10:07 a.m. (see 10:05 a.m.-10:08 a.m. September 11, 2001).

John Werth, the air traffic controller at the FAA’s Cleveland Center who is monitoring the now-hijacked Flight 93, has to move Delta Air Lines Flight 1989 and several other aircraft, in order to get them out of Flight 93’s path and avoid a midair collision. [9/11 Commission, 8/26/2004, pp. 39; USA Today, 9/11/2008]
Controller Begins Moving Aircraft - At 9:30 a.m., Werth begins moving other aircraft away from Flight 93 due to the hijacked flight’s failure to acknowledge his radio transmissions. [Federal Aviation Administration, 9/17/2001 pdf file] Furthermore, as USA Today will describe, Flight 93 “became erratic. It sped up and started gaining on another United [Airlines] flight. Werth commanded the second jet to turn right. Seconds later, Flight 93 turned to the right, too.” [USA Today, 9/11/2008]
Controller Worried about Possible Collision - Then, between 9:34 a.m. and 9:38 a.m., Flight 93 climbs from 35,000 feet up to 41,000 feet (see (9:35 a.m.) September 11, 2001), and during this period it reverses course and heads back east (see (9:36 a.m.) September 11, 2001). [National Transportation Safety Board, 2/19/2002 pdf file; 9/11 Commission, 8/26/2004, pp. 39, 41] Werth becomes concerned about the possibility of a midair collision. [9/11 Commission, 10/1/2003 pdf file]
Delta 1989 Turns Several Times - As Flight 93 climbs, Werth instructs Delta 1989, which is also in the airspace he is monitoring, to turn right, so as to get away from the hijacked jet. As Flight 93 continues its turn back toward the east, Werth has to move Delta 1989 out of its path. In all, he has to turn the Delta flight several times. [USA Today, 9/11/2008] Minutes earlier, Cleveland Center concluded incorrectly that Delta 1989, not Flight 93, was the aircraft being hijacked (see (9:28 a.m.-9:33 a.m.) September 11, 2001). [USA Today, 8/13/2002] The Delta pilots’ normal responses to his instructions reassure Werth that it is a “safe bet that the Delta flight hadn’t been hijacked.” [USA Today, 9/11/2008]
Other Aircraft Moved out of Path - According to the 9/11 Commission, while Flight 93 is ascending to 41,000 feet, Werth has to move “several aircraft out of its way,” acting “decisively to clear the other flights in his sector from Flight 93’s path.” [9/11 Commission, 8/26/2004, pp. 39]

Even after they take off, the three fighter pilots who are scrambled from Langley Air Force Base in Virginia are unaware of what is happening regarding the ongoing attacks. The three F-16s were airborne at 9:30 (see (9:25 a.m.-9:30 a.m.) September 11, 2001). But according to the 9/11 Commission, the pilots are “never briefed about the reason” they are scrambled. “The pilots [know] their mission [is] to divert aircraft, but [do] not know that the threat [is coming] from hijacked airliners.” [9/11 Commission, 7/24/2004, pp. 27 and 45] One of the pilots, Captain Craig Borgstrom, will later recall that it is only when they see the burning Pentagon that they start piecing things together: “[A]s you get closer, you start thinking, ‘OK, maybe there’s some type of attack going on.’ You start correlating Washington, DC, with New York. We still have no ‘intel’ brief of what’s going on.… We knew something terribly wrong was going on.” [Filson, 2003, pp. 65-66] He says he “had no idea” that the Pentagon and World Trade Center had been hit by suicide terrorists in airplanes. [Christian Science Monitor, 4/16/2002] The Langley pilots will only learn about Flight 93 and a plane crashing in Pennsylvania when they return to their base at around 2:00 p.m. [Longman, 2002, pp. 222]

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).

FAA Administrator Jane Garvey notifies the video conference chaired by counterterrorism “tsar” Richard Clarke that all aircraft have been ordered to land at the nearest field and reads a list of potential hijacks including Delta 1989 and United 93. [Clarke, 2004, pp. 5] Although, according to Clarke’s account, both General Richard Myers and Secretary of Defense Donald Rumsfeld are present at the conference at this point, the 9/11 Commission will later claim that the military was not notified about the hijacking of United 93 until over half an hour later (see 10:03 a.m. September 11, 2001).

According to the 9/11 Commission, word of Flight 93’s hijacking reaches FAA headquarters. By this time, headquarters has established an open line of communication with the FAA Command Center at Herndon, Virginia. It had instructed the center to poll all flight control centers about suspect aircraft. So, at this time, the Command Center passes on Cleveland’s message: “United 93 may have a bomb on board.” The FAA headquarters apparently does not forward this information to the military, despite having the responsibility for doing so. Ben Sliney, the FAA’s national operations manager at its Herndon Command Center, will later recount, “I do know that all the information was being relayed to headquarters and, at least as far as we were concerned, it should have been. We thought it had been given to the military at each juncture.” The Command Center continually updates FAA headquarters on Flight 93 until it crashes. [9/11 Commission, 6/17/2004; CBC, 9/12/2006]

Military officers at the FAA’s Command Center are informed of the hijacking of Flight 93, according to the FAA’s National Operations Manager Ben Sliney. If such notification is given, it is presumably shortly after the Command Center learns of the hijacking (see 9:34 a.m. September 11, 2001). Sliney will later tell the 9/11 Commission: “Available to us at the Command Center of course is the military cell, which was our liaison with the military services. They were present at all of the events that occurred on 9/11.” He will add, “The normal protocols for the events that were transpiring then—that is to say hijacked aircraft, which requires a notification to NORAD—those, at least I was given to understand, were made promptly—the notifications on each hijack.” The FAA’s acting Deputy Administrator Monte Belger will add: “[T]here were military people on duty at the FAA Command Center, as Mr. Sliney said. They were participating in what was going on. There were military people in the FAA’s Air Traffic Organization in a situation room. They were participating in what was going on.” [9/11 Commission, 6/17/2004] If the cell is notified, it is unclear what, if anything, the military liaison officers—Colonel John Czabaranek, Lieutenant Colonel Michael-Anne Cherry, and Major Kevin Bridges (see (Between 9:04 a.m. and 9:25 a.m.) September 11, 2001)—at the Command Center do with the information about Flight 93’s hijacking. The 9/11 Commission will say that the first notification to the military about Flight 93 comes at 10:07 a.m. (see 10:05 a.m.-10:08 a.m. September 11, 2001).

According to the later claims of several senior officials, the US military is tracking Flight 93 as it heads east and is ready to shoot it down if necessary.
bullet According to Brigadier General Montague Winfield, the Pentagon’s National Military Command Center (NMCC) has “received the report from the FAA that Flight 93 had turned off its transponder, had turned, and was now heading towards Washington, DC.” Winfield will add, “The decision was made to try to go intercept Flight 93.” [ABC News, 9/11/2002]
bullet General Richard Myers, the acting chairman of the Joint Chiefs of Staff, will write that in the NMCC, “We learned that there was apparently a fourth hijacked aircraft, United Airlines Flight 93 out of Newark, bound nonstop for San Francisco. Like the other planes, it had switched off its transponder, making it much harder if not impossible to track on ground radar.” [Myers, 2009, pp. 152]
bullet Major General Larry Arnold, the commander of the Continental United States NORAD Region, will say, “I was personally anxious to see what 93 was going to do, and our intent was to intercept it.” Three fighters have taken off from Langley Air Force Base in Virginia (see (9:25 a.m.-9:30 a.m.) September 11, 2001). According to Arnold, “we launched the aircraft out of Langley to put them over top of Washington, DC, not in response to American Airline 77, but really to put them in position in case United 93 were to head that way.” [9/11 Commission, 5/23/2003] He says, “as we discussed it in the conference call, we decided not to move fighters toward 93 until it was closer because there could have been other aircraft coming in,” but adds, “I had every intention of shooting down United 93 if it continued to progress toward Washington, DC… whether we had authority or not.” [Filson, 2003, pp. 73]
bullet Colonel Robert Marr, the battle commander at NORAD’s Northeast Air Defense Sector (NEADS), is reportedly “focused on United Flight 93, headed straight toward Washington.” He will concur with Arnold, saying: “United Airlines Flight 93 would not have hit Washington, DC. He would have been engaged and shot down before he got there.” [Filson, 2003, pp. 73] Marr and Arnold will both say they were tracking Flight 93 even earlier on, while it was still heading west (see Shortly Before 9:36 a.m. September 11, 2001).
Yet, contradicting these claims, the 9/11 Commission will conclude that the military only learns about Flight 93 around the time it crashes. It says the NMCC learns of the hijacking at 10:03 a.m. (see 10:03 a.m. September 11, 2001). Based upon official records, including recordings of the NEADS operations floor, it says NEADS never follows Flight 93 on radar and is first alerted to it at 10:07 a.m. (see 10:05 a.m.-10:08 a.m. September 11, 2001).

The National Military Command Center (NMCC) at the Pentagon commences an “air threat conference” at 9:37 a.m. in response to the terrorist attacks, which will last for more than eight hours and have numerous high-level government and military officials participating at various times.
NORAD Reports Two More Hijackings - Captain Charles Leidig opens the call at 9:39 a.m. [9/11 Commission, 7/24/2004, pp. 37-38] As the acting deputy director for operations (DDO) in the NMCC during the attacks, Leidig is responsible for moderating the air threat conference and generating a military response to the crisis. [9/11 Commission, 4/29/2004 pdf file] He begins the call saying: “An air attack against North America may be in progress. NORAD, what’s the situation?” NORAD says it has conflicting reports, and its latest information is of “a possible hijacked aircraft taking off out of JFK [International Airport in New York], en route to Washington, DC.” [9/11 Commission, 7/24/2004, pp. 38] NORAD says the FAA has also passed it information about a second additional hijacking. Major Charles Chambers, who is currently on duty in the NMCC, will later recall, “This was probably a communications mix-up, but we all thought for a while that there were a total of five hijackings.” [US Department of Defense, 9/2001]
NMCC Reports Pentagon Attack - The NMCC reports that there has been a crash into the mall side of the Pentagon and requests that the secretary of defense be added to the conference. (However, despite being in the Pentagon when it is hit, Defense Secretary Donald Rumsfeld will not enter the NMCC and join the air threat conference until around 10:30 a.m. (see (10:30 a.m.) September 11, 2001).) [9/11 Commission, 7/24/2004, pp. 38] The air threat conference is broadcast over a loudspeaker inside the NMCC. [US News and World Report, 8/31/2003] According to Chambers, “Questions were flying left and right on the conference, and trying to keep things straight was very difficult.” [US Department of Defense, 9/2001]
NORAD Recommended Air Threat Conference - Leidig and Commander Pat Gardner, the assistant DDO, had earlier on decided to convene an all-purpose “significant event conference” in response to the attacks on the World Trade Center. That call commenced at 9:29 a.m. (see 9:29 a.m.-9:34 a.m. September 11, 2001). NORAD had recommended that it be reconvened as an air threat conference. [9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 37] According to Chambers, an air threat conference is used when aircraft are considered to be hostile and involves many more people than are in a significant event conference, including the chairman of the Joint Chiefs of Staff, the secretary of defense, and officials from the White House. [US Department of Defense, 9/2001] However, Leidig thought a significant event conference was the correct kind of call for the situation. He will tell the 9/11 Commission that an air threat conference “had Cold War implications and brought a different group of people to a conference.” [9/11 Commission, 4/29/2004 pdf file] Gardner will say that threat conferences are intended for dealing with external threats. [9/11 Commission, 5/12/2004]
Deputy Director Ordered Upgrading of Conference - All the same, Leidig gave the order to transition to an air threat conference. [9/11 Commission, 7/24/2004, pp. 37] He will tell the 9/11 Commission that, in retrospect, the reason he thinks he did so “was because he perceived an air threat at that time.” [9/11 Commission, 4/29/2004 pdf file] Therefore, the significant event conference was brought to an end at around 9:34 a.m., and resumes as an air threat conference three minutes later. [9/11 Commission, 7/24/2004, pp. 37] Staff Sergeant Val Harrison could have established the air threat conference either by leaving all of those participating in the significant event conference on the line and then adding new participants one at a time, or by simply hanging up on everyone in the significant event conference and then having the computer do a mass dialing. Harrison recommended the second option. Leidig had agreed, and directed her to disconnect the conference call and start over.
Problem with Connecting Some Agencies - As happened with the significant event conference, there are problems connecting several agencies to the air threat conference. [US Department of Defense, 9/2001] Despite repeated attempts, operators struggle to get the FAA connected (see (9:29 a.m.-12:00 p.m.) September 11, 2001), and it will take until 10:17 a.m. for an FAA representative to finally join the call (see 10:17 a.m. September 11, 2001). [9/11 Commission, 7/21/2003 pdf file; 9/11 Commission, 7/24/2004, pp. 37] Other agencies had not understood what Leidig meant about convening the new conference, and so did not hang up their phones when the NMCC disconnected the previous conference call. As a result, all the NMCC got from them was a busy signal over the line. Chambers will recall, “As with the [significant event conference], it took longer than expected to convene the [air threat conference].” [US Department of Defense, 9/2001]
Top Officials Participate - Throughout the more than eight hours the air threat conference is running for, numerous key officials will participate in it at various times, including President Bush, Vice President Dick Cheney, Deputy National Security Adviser Stephen Hadley, acting Chairman of the Joint Chiefs of Staff Richard Myers, military personnel from the Presidential Emergency Operations Center below the White House, and the president’s military aide on Air Force One. [9/11 Commission, 7/24/2004, pp. 37] Brigadier General Montague Winfield, the original DDO, who had Leidig take his place so he could attend a pre-scheduled meeting (see 8:30 a.m. September 11, 2001), will later recall, “All of the governmental agencies… that were involved in any activity that was going on in the United States… were in that conference.” [ABC News, 9/11/2002]
Winfield Runs Conference after Returning to Post - Winfield will take over the running of the air threat conference from Leidig after returning to his post at around 10:30 a.m. (see (10:30 a.m.) September 11, 2001). [CNN, 9/4/2002; 9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 6/17/2004] But although NMCC conference calls are moderated by the DDO, Rumsfeld will use the DDO’s phone to participate in the air threat conference, meaning that Winfield is unable to moderate the conference when the defense secretary is participating.

Sabra Kaulia.Sabra Kaulia. [Source: Aircraft Owners and Pilots Association]The US Air Force liaison to the FAA joins a teleconference that has been established by the FAA shortly after the time of the Pentagon attack, according to her own later recollections, although an FAA statement will claim she joined it significantly earlier. [9/11 Commission, 5/23/2003; 9/11 Commission, 3/26/2004; US Department of Transportation, 8/31/2006 pdf file]
Watches Television, Does Not Join Teleconference - The Air Force liaison, Colonel Sheryl Atkins, will recall that she arrived at FAA headquarters in Washington, DC, around five to 10 minutes after the first attack in New York (see (Between 8:51 a.m. and 8:56 a.m.) September 11, 2001), and went to her fourth-floor office there. She will describe: “Everybody was there around the TV. We watched the events unfold. At first, we were kind of hanging back and saying, you know, ‘there’s something awful going on with the air traffic system.‘… But at a certain point, not too long after that, it became obvious that, you know, something really strange is going on.”
Heads to Situation Room - Shortly after 9:37 a.m., when the Pentagon is hit, Atkins hears CNN reporting a bomb may have gone off at the Pentagon. She will recall that she then heads up to the 10th floor of the headquarters building along with Sabra Kaulia, the program director for air traffic airspace management, and goes to the air traffic situation room, where David Canoles, the FAA’s manager of air traffic evaluations and investigations, is participating in a teleconference. [9/11 Commission, 3/26/2004; US Department of Transportation, 8/31/2006 pdf file] According to a 2003 statement provided by the FAA, the FAA established this teleconference with several other agencies “[w]ithin minutes” of the first attack in New York (see (8:50 a.m.) September 11, 2001). [9/11 Commission, 5/23/2003] Atkins will say she is then “in and out” of the air traffic situation room throughout the morning. She does not speak with any of the military representatives at the White House, but does work directly with Steve Nolte, the airspace manager at NORAD, and also communicates with Lieutenant Colonel Michael-Anne Cherry, who is at the FAA’s Herndon Command Center, to exchange information. [9/11 Commission, 3/26/2004]
FAA Claims Atkins Joined Teleconference Earlier - In a 2003 statement it provides to the 9/11 Commission the FAA will say Atkins joined the teleconference significantly earlier than she claims. According to the statement, the “US Air Force liaison to the FAA [i.e. Atkins] immediately joined the FAA headquarters phone bridge” that was set up minutes after the first attack in New York, “and established contact with NORAD on a separate line.” [9/11 Commission, 5/23/2003]
Other Liaisons Arrive Later On - As well as Atkins, who represents the Air Force, liaisons representing the other three military services within the Department of Defense (the Army, the Navy, and the Marine Corps) work at FAA headquarters. However, Atkins is the only military liaison currently there. The Navy and Marine Corps liaisons will arrive at FAA headquarters at around 10:30 a.m. and join Atkins on the building’s 10th floor, from where they help establish and maintain critical communications channels between the Defense Department and the FAA. The Army liaison will not arrive at FAA headquarters until the following day. [Federal Aviation Administration, 3/21/2002 pdf file; 9/11 Commission, 3/26/2004]

[9/11 Commission, 2004; Vanity Fair, 8/1/2006] Boston Center previously called NEADS at 9:27 and said that Delta 1989 was missing (see 9:27 a.m. September 11, 2001). [North American Aerospace Defense Command, 9/11/2001; 9/11 Commission, 5/23/2003]
NEADS Technicians Respond - At NEADS, Stacia Rountree, the ID technician who takes Scoggins’s call, announces to her colleagues: “Delta ‘89, that’s the hijack. They think it’s possible hijack.… South of Cleveland.” The plane’s transponder is still on, and she adds, “We have a code on him now.” Rountree’s team leader, Master Sergeant Maureen Dooley, instructs: “Pick it up! Find it!” The NEADS technicians quickly locate Delta 1989 on their radar screens, just south of Toledo, Ohio, and start alerting other FAA centers to it. [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 177] NEADS mission crew commander Major Kevin Nasypany will be notified by his staff of the suspected hijacking at about 9:41 or 9:42 a.m. [9/11 Commission, 1/22/2004 pdf file] NEADS never loses track of Delta 1989. It will follow it on radar as it reverses course over Toledo, heads east, and then lands in Cleveland (see (10:18 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 28] It will order Air National Guard fighter jets from Selfridge and Toledo to intercept the flight (see (9:55 a.m.) September 11, 2001 and 10:01 a.m. September 11, 2001). [Spencer, 2008, pp. 178-179] But it will soon learn that Delta 1989 is not in fact hijacked. [9/11 Commission, 7/24/2004, pp. 28]
Cleveland Center, Not Boston, Handling Delta 1989 - Although Boston Center notifies NEADS of the suspected hijacking, Delta 1989 is in fact being handled by the FAA’s Cleveland Center. [USA Today, 8/13/2002; 9/11 Commission, 7/24/2004, pp. 10-12] Cleveland Center air traffic controllers suspected that Delta 1989 had been hijacked at around 9:30 a.m. (see (9:28 a.m.-9:33 a.m.) September 11, 2001), but apparently only informed the FAA’s Command Center, and not NEADS, of this. [USA Today, 8/13/2002] To explain why Boston Center alerts NEADS to the flight, the 9/11 Commission will later comment that, “Remembering the ‘we have some planes’ remark” (see 8:24 a.m. September 11, 2001), the Boston Center simply “guessed that Delta 1989 might also be hijacked.”
Similar to First Two Hijacked Planes - Like Flights 11 and 175, the two aircraft that have crashed into the World Trade Center (see 8:46 a.m. September 11, 2001 and 9:03 a.m. September 11, 2001), Delta 1989 took off from Boston’s Logan Airport. [9/11 Commission, 7/24/2004, pp. 27-28] According to the New York Times, it left there at about the same time as Flights 11 and 175 did, meaning around 8:00 to 8:15 a.m. [New York Times, 10/18/2001; 9/11 Commission, 7/24/2004, pp. 32] Like those two aircraft, it is a Boeing 767. [USA Today, 8/13/2002; 9/11 Commission, 7/24/2004, pp. 27-28] But, unlike those flights, its transponder has not been turned off, and so it is still transmitting a beacon code. [9/11 Commission, 7/24/2004, pp. 28; Vanity Fair, 8/1/2006] It is unclear what Delta 1989’s intended destination is. According to some accounts, like Flights 11 and 175 were, it is bound for Los Angeles. [Associated Press, 9/11/2001; New York Times, 10/18/2001; USA Today, 8/13/2002; Arizona Daily Star, 9/24/2007; Spencer, 2008, pp. 167] Other accounts will say that its destination is Las Vegas. [9/11 Commission, 7/24/2004, pp. 28; Vanity Fair, 8/1/2006] Personnel at NEADS are apparently informed that Las Vegas is the intended destination. Around this time, one member of staff there tells her colleagues that the flight is “supposed to go to Vegas.” [North American Aerospace Defense Command, 9/11/2001]
One of Numerous Incorrect Reports - The 9/11 Commission will comment: “During the course of the morning, there were multiple erroneous reports of hijacked aircraft (see (9:09 a.m. and After) September 11, 2001). The report of American 11 heading south was the first (see 9:21 a.m. September 11, 2001); Delta 1989 was the second.” [9/11 Commission, 7/24/2004, pp. 28]

After learning that Delta flight 1989 may have been hijacked from Boston flight control (see 9:39 a.m. September 11, 2001), NEADS calls Cleveland flight control, which is handling the flight, to discuss this. [9/11 Commission, 7/24/2004, pp. 14] Although Cleveland flight control has been aware that United 93 has been hijacked since before 9:30, it apparently fails to mention this to NEADS. According to the 9/11 Commission, the NMCC is not notified of United 93’s hijacking until 10:03 (see 10:03 a.m. September 11, 2001).

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).

Cook, who is currently at ACC headquarters at Langley Air Force Base, Virginia, receives the call “less than one hour after” the first hijacked plane crashed into the World Trade Center (see 8:46 a.m. September 11, 2001), according to journalist and author Richard Whittle, which means the call is made before around 9:45 a.m. The caller, Whittle will write, says that the “White House [wants] to know how soon the Air Force could get three Predators over Afghanistan—with missiles under their wings.” The identity of the caller is unstated. Later this morning, Cook will talk to Colonel Ed Boyle, director of intelligence for the ACC, who is away in Arizona, and pass on this information to him (see (After 10:00 a.m.) September 11, 2001).

FAA National Operations Manager Ben Sliney.FAA National Operations Manager Ben Sliney. [Source: Publicity photo]Ben Sliney, FAA’s National Operations Manager, orders the entire nationwide air traffic system shut down. All flights at US airports are stopped. Around 3,950 flights are still in the air. Sliney makes the decision without consulting FAA head Jane Garvey, Transportation Secretary Norman Mineta, or other bosses, but they quickly approve his actions. It’s Sliney’s first day on the job.

The plane that has been flying General Henry Shelton, the chairman of the Joint Chiefs of Staff, over the Atlantic Ocean has to spend two hours in a “holding pattern” near Greenland and then more time in a holding pattern over Canada before it is cleared to fly back into the United States. [Air Force Magazine, 9/2011 pdf file] Shelton was flying toward Europe for a NATO conference (see 7:15 a.m. September 11, 2001), but, after he learned of the attacks on the World Trade Center, ordered that his plane turn around and return to the US (see (8:50 a.m.-10:00 a.m.) September 11, 2001). However, air traffic controllers have denied the request to do so because US airspace has been shut down (see (9:45 a.m.) September 11, 2001). [Federal Aviation Administration, 3/21/2002, pp. G-1 pdf file; Shelton, Levinson, and McConnell, 2010, pp. 430-432]
Plane Has to Fly in a Holding Pattern near Greenland - Therefore, although Shelton’s plane, nicknamed “Speckled Trout,” does turn around, it doesn’t initially fly back to the United States. For a couple of hours, since its crew doesn’t have clearance to return to the US and it doesn’t have a destination, the plane goes into a “holding pattern” near Greenland. Captain Rob Pedersen, the flight navigator, comes up with a list of alternative landing sites, which include Thule Air Base in Greenland and Naval Air Station Keflavik in Iceland. Although the crew decides to head back to the US, Pedersen will later recall, it is still difficult to get a security clearance, even for such a high-profile passenger as Shelton.
Plane Goes into Another Holding Pattern over Canada - Speckled Trout eventually reaches Canada, but the plane is still refused entry into US airspace and so it goes into a holding pattern again. “In the beginning we had a few problems convincing [the air traffic controller] to allow us back into the country, [even though] we were ordered at a significantly high level to come back,” Pedersen will recall. “You can’t say over the radio who you are carrying because they don’t have secure communications at the FAA.… We had to tell them over an open line that we had a DV Code 2, which is a ranking that a lot of DVs [distinguished visitors] fall under.” Eventually, the crew receives permission to fly into the US, although the time when this occurs is unstated. “It took a little bit of time, and I’m sure there were a lot of phone calls made, before they let us back in,” Pedersen will say. [Air Force Magazine, 9/2011 pdf file] Shelton, however, will contradict this account and claim his plane is cleared to enter US airspace significantly earlier. He will recall that those on the plane are told they have permission to enter US airspace 10 minutes after he talks on the phone with General Richard Myers, vice chairman of the Joint Chiefs of Staff (see (Shortly After 10:00 a.m.) September 11, 2001), which would mean they receive clearance possibly as early as around 10:15 a.m. [Shelton, Levinson, and McConnell, 2010, pp. 432-433]
Myers Takes Shelton's Place as Chairman While Shelton Is outside the US - After flying over New York, Speckled Trout will land at Andrews Air Force Base, just outside Washington, DC, at 4:40 p.m. (see 4:40 p.m. September 11, 2001). [Federal Aviation Administration, 9/11/2001 pdf file; UNC-TV, 1/27/2013] While the plane is being denied permission to enter US airspace, Myers remains as the acting chairman of the Joint Chiefs of Staff in Shelton’s place. This is “how the law reads whenever the chairman is out of the country,” Shelton will write. “Until I crossed back into United States airspace, all the decisions would be Dick’s to make, in conjunction with Secretary [of Defense Donald] Rumsfeld and the president.” [Shelton, Levinson, and McConnell, 2010, pp. 432]

Doug Davis.Doug Davis. [Source: Federal Aviation Administration]John White, a manager at the FAA’s Command Center, suggests to Doug Davis, the special assistant for technical operations in air traffic services at FAA headquarters, that fighter jets should be launched in response to Flight 93. However, FAA headquarters is apparently unable to act on this suggestion. [Federal Aviation Administration, 10/21/2002; 9/11 Commission, 7/24/2004, pp. 29; Canadian Broadcasting Corporation, 9/10/2006] In the last few minutes, the Command Center has warned headquarters that Flight 93 is “29 minutes out of Washington” and approaching the city (see 9:41 a.m.-9:48 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 44]
Command Center Asks about Launching Fighters - Davis now tells White, “They’re pulling Jeff [Griffith, the FAA’s deputy director of air traffic] away to go talk about United 93.” White asks, “Uh, do we want to think, uh, about scrambling aircraft?” Davis replies, “Oh, God, I don’t know.” White says, “Uh, that’s a decision somebody’s gonna have to make probably in the next 10 minutes.” However, Davis only responds, “Uh, ya know everybody just left the room.” [Federal Aviation Administration, 10/21/2002; 9/11 Commission, 7/24/2004, pp. 29] This conversation takes place 13 minutes after the FAA’s Cleveland Center asked the Command Center whether anyone had asked the military to launch fighter jets to intercept Flight 93 (see (9:36 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 40]
Person Who Could Request Fighters Is Unavailable - Apparently there is only one person at FAA headquarters who is authorized to request military assistance, and Ben Sliney, the Command Center’s national operations manager, is told that no one can find him. Sliney will later recount: “I said something like, ‘That’s incredible. There’s only one person. There must be someone designated or someone who will assume the responsibility of issuing an order, you know.’ We were becoming frustrated in our attempts to get some information. What was the military response?” [Canadian Broadcasting Corporation, 9/10/2006] This lack of response to Flight 93 contrasts with the FAA’s earlier reaction to Flight 11, when Boston Center air traffic controllers contacted NORAD’s Northeast Air Defense Sector (NEADS) themselves (see (8:37 a.m.) September 11, 2001), and even called military bases directly (see 8:34 a.m. September 11, 2001 and (8:34 a.m.) September 11, 2001).

[Source: FAA]The three F-16 fighter jets launched from Langley Air Force Base (see (9:25 a.m.-9:30 a.m.) September 11, 2001) that have been directed toward Washington request and are given permission to fly at high altitude over the city. After the Langley AFB pilots are given the correct coordinates they are to head to (see (Between 9:41 a.m. and 9:50 a.m.) September 11, 2001), at 9:51 lead pilot Major Dean Eckmann looks on his radar screen and sees that the area where he has been directed to set up a combat air patrol is filled with air traffic. He therefore contacts the FAA’s Washington Center and tells the controller, “I need 3,000 feet of altitude in a 20-mile ring around DC.” When the controller asks the reason, Eckmann replies, “Higher headquarters’ request!” The controller gives him an altitude range of 25,000 to 27,000 feet. Eckmann radios the other two Langley pilots and gives them their altitude assignments: he’ll fly at 25,000 feet, Major Brad Derrig will be at 26,000 feet, and Captain Craig Borgstrom at 27,000 feet. According to author Lynn Spencer, the jets then head toward Washington at 700 miles per hour, just under the speed of sound. [Spencer, 2008, pp. 180-182] However, Spencer’s account of this incident conflicts with the 1st Air Force’s book about the 9/11 attacks. According to that account, several minutes before Eckmann reportedly asks for altitude clearance—at around 9:45 a.m.—he had been directed to drop to lower altitude to check out two unidentified aircraft, and was then told to inspect the Pentagon (see (9:45 a.m.) September 11, 2001).

Swanson / US Air Force]NORAD’s Northeast Air Defense Sector (NEADS) contacts Selfridge Air National Guard Base in Michigan to arrange for two of its F-16 fighter jets that are out on a training mission to intercept a suspicious aircraft. Accounts will conflict over whether this aircraft is Flight 93 or Delta Air Lines Flight 1989, which is wrongly thought to have been hijacked. [Associated Press, 8/30/2002; ABC News, 9/11/2002; Vanity Fair, 8/1/2006; Spencer, 2008, pp. 178] Delta 1989 was flying about 25 miles behind Flight 93 when air traffic controllers mistakenly suspected it might be hijacked (see (9:28 a.m.-9:33 a.m.) September 11, 2001), and since then it has been instructed to land at Cleveland Hopkins Airport in Ohio (see (9:42 a.m.) September 11, 2001). [USA Today, 8/13/2002; USA Today, 9/11/2008] Flight 93 is currently flying east across Pennsylvania. [National Transportation Safety Board, 2/19/2002 pdf file] NEADS has already tried getting fighter jets from a unit in Duluth, Minnesota, sent after Delta 1989, but the unit was unable to respond (see (Shortly After 9:41 a.m.) September 11, 2001). [9/11 Commission, 1/22/2004 pdf file; 9/11 Commission, 1/23/2004 pdf file]
NEADS Calls Selfridge Base - A NEADS weapons technician now calls the 127th Wing at Selfridge Air National Guard Base. He knows the unit has two F-16s in the air on a training mission. Although these jets are unarmed and only have a limited amount of fuel remaining, the commander at the Selfridge base agrees to turn them over to NEADS. [Spencer, 2008, pp. 178] The commander says: “[H]ere’s what we can do. At a minimum, we can keep our guys airborne. I mean, they don’t have—they don’t have any guns or missiles or anything on board.” The NEADS technician replies, “It’s a presence, though.” [Vanity Fair, 8/1/2006]
Fighters May Have to Crash into Hijacked Plane - Military commanders realize that, without weapons, the Selfridge fighter pilots might have to slam their jets into a hijacked plane to stop it in its tracks. Colonel Robert Marr, the NEADS battle commander, will later reflect, “As a military man, there are times that you have to make sacrifices that you have to make.” [ABC News, 8/30/2002; ABC News, 9/11/2002] However, the Selfridge jets never have to intercept either of the two suspect aircraft, and instead are able to head back to base. [Filson, 2003, pp. 70; Wolverine Guard, 9/2006 pdf file]
Selfridge Called due to Concerns about Delta 1989? - According to author Lynn Spencer, the NEADS weapons technician’s call to the Selfridge unit is made in response to a report NEADS received about the possible hijacking of Delta 1989 (see 9:39 a.m. September 11, 2001). [Spencer, 2008, pp. 178] Vanity Fair magazine and the 9/11 Commission will also say NEADS calls the Selfridge unit in response to this report about Delta 1989. [9/11 Commission, 7/24/2004, pp. 28; Vanity Fair, 8/1/2006]
NORAD Commander Gives Different Account - However, Larry Arnold, the commander of the Continental United States NORAD Region, will suggest the Selfridge unit is called due to concerns about both Delta 1989 and Flight 93. He will say: “We were concerned about Flight 93 and this Delta aircraft [Flight 1989] and were trying to find aircraft in the vicinity to help out. We didn’t know where it was going to go. We were concerned about Detroit… and the fighters up there were out of gas with no armament.” [Filson, 2003, pp. 71]
NEADS Commander Claims Fighters Sent toward Flight 93 - Robert Marr will give another different account. He will claim that NEADS contacts the Selfridge base solely because of its concerns over Flight 93. He tells author Leslie Filson that before Flight 93 reversed course and headed back east (see (9:36 a.m.) September 11, 2001), NEADS thought it was “headed toward Detroit or Chicago. I’m thinking Chicago is the target and know that Selfridge Air National Guard Base has F-16s in the air.” NEADS contacts “them so they could head off 93 at the pass.” [Filson, 2003, pp. 68] Marr will tell the 9/11 Commission that the Selfridge F-16s are going to be “too far from Cleveland to do any good,” and so he believes NEADS directs them to intercept Flight 93. [9/11 Commission, 1/23/2004 pdf file] (Presumably, he means the jets cannot be responding to Delta 1989, which has been told to land in Cleveland [USA Today, 9/11/2008] )
9/11 Commission Disputes Arnold's and Marr's Accounts - The 9/11 Commission will reject Arnold’s and Marr’s accounts. It will state, “The record demonstrates, however, that… the military never saw Flight 93 at all” before it crashes, and conclude, “The Selfridge base was contacted by NEADS not regarding Flight 93, but in response to another commercial aircraft in the area that was reported hijacked (Delta Flight 1989, which ultimately was resolved as not hijacked).” [9/11 Commission, 8/26/2004, pp. 101] Lt. Col. Doug Champagne, the pilot of one of the Selfridge F-16s, will recall that “he and his colleague never received orders to intercept [Flight 93] in any way.” [Mount Clemens-Clinton-Harrison Journal, 9/6/2006] Reports based on interviews with the two Selfridge pilots will make no mention of the jets being directed to intercept Delta 1989 either (see (9:56 a.m.-10:29 a.m.) September 11, 2001).

A US Park Police helicopter flying above the burning Pentagon.A US Park Police helicopter flying above the burning Pentagon. [Source: Mark D. Faram / US Navy]A US Park Police helicopter that recently arrived over the Pentagon is contacted by an air traffic controller at Washington’s Reagan National Airport and given responsibility for controlling the airspace over Washington, DC, since the control tower at Reagan Airport is being evacuated. [US Naval Historical Center, 11/20/2001; US Department of Health and Human Services, 7/2002, pp. A-48 pdf file; McDonnell, 2004, pp. 21 pdf file] The Park Police Aviation Unit’s two helicopters arrived at the Pentagon within minutes of the attack there (see Shortly After 9:37 a.m. September 11, 2001). [Rotor and Wing, 11/2001] While one of the helicopters landed to conduct medical evacuations, the other, which has the call sign “Eagle I,” circled overhead. [US Naval Historical Center, 11/20/2001; McDonnell, 2004, pp. 20-21 pdf file]
Airport Tower Being Evacuated - Eagle I has made three or four orbits around the Pentagon when a controller in the Reagan Airport tower radios its pilot, Sergeant Ronald Galey. The controller says the tower is currently evacuating. [US Naval Historical Center, 11/20/2001; National Park Service, 1/17/2002] According to some accounts, the tower is being evacuated due to reports of more hijacked aircraft heading in its direction (see (9:55 a.m.) September 11, 2001). [NBC 4, 9/11/2003; Spencer, 2008, pp. 215-216] But according to other accounts, the controller tells Galey the tower is evacuating because it is being affected by smoke that is drifting across from the burning Pentagon. [US Department of Health and Human Services, 7/2002, pp. A-48 pdf file; McDonnell, 2004, pp. 21 pdf file; Goldberg et al., 2007, pp. 162] Galey will recall the controller saying: “Eagle I, we can’t see anything outside the tower. [The smoke is] getting in our ventilation system. We’re abandoning the tower.” Therefore, the controller gives Galey control of the airspace for the entire Washington area, telling him, “You’ve got the airspace.” [US Naval Historical Center, 11/20/2001; McDonnell, 2004, pp. 21 pdf file]
Pilot Alarmed at Being Given Control of Airspace - The control tower at Reagan Airport is “normally the ‘nerve center’ for directing any response to this type of incident,” according to a National Park Service news article. [National Park Service, 9/21/2002] Galey is initially alarmed. He will recall thinking, “Exactly what I need right now is I’ve got control of the airspace.” [US Naval Historical Center, 11/20/2001] However, he is unaware that the FAA has ordered that all airborne aircraft must land at the nearest airport (see (9:45 a.m.) September 11, 2001), which will make his task easier. [US Congress. House. Committee On Transportation And Infrastructure, 9/21/2001; McDonnell, 2004, pp. 21 pdf file; 9/11 Commission, 7/24/2004, pp. 29]
NORAD Advises Pilot on Controlling Airspace - The controller gives Galey the radio frequency for NORAD, and tells him to contact NORAD. [National Park Service, 1/17/2002; McDonnell, 2004, pp. 21-22 pdf file] The person Galey then talks to at NORAD informs him: “Look, you have no [air] traffic in DC, except for the traffic that you’re calling. The aircraft that you’re calling in, we’re going to allow to come in. Other than that, there should be no one besides the military, and we’ll call you out the military traffic.” Galey will later reflect: “So that helped tremendously. That function alone was not very taxing.” [US Naval Historical Center, 11/20/2001] The person at NORAD also tells Galey there is “an unauthorized aircraft inbound from the Pennsylvania area, with the estimated time of arrival approximately 20 minutes into DC.” Galey will recall that he and the rest of his crew discuss what they should do, and decide that “we’d take our chances and stay there [at the Pentagon], and do what we came there to do.” [National Park Service, 1/17/2002]
Airspace Control Passed on to Metropolitan Police Helicopter - Eagle I becomes “the air traffic control function for the area, flying a slow racetrack pattern over the site and clearing aircraft in and out,” according to Lieutenant Philip Cholak, the Park Police Aviation Unit commander. [Aviation International News, 10/1/2001] But after a time Galey asks his paramedic to request that a Metropolitan Police helicopter be launched to take over the command and control of the Washington airspace. He tells the paramedic: “You know we’re going to have to do a medevac mission here. We’re going to have to relinquish the command/control function to somebody else.” A Metropolitan Police helicopter subsequently arrives and relieves Eagle I of its command and control function.

McChord Air Force Base.McChord Air Force Base. [Source: Michel Teiten]Major Kevin Nasypany, the mission crew commander at NORAD’s Northeast Air Defense Sector (NEADS), calls NORAD’s Western Air Defense Sector (WADS), which is at McChord Air Force Base in Washington State, to request assistance. He says: “I’d like to… steal some aircraft out of Fargo from you guys.… Bring up the weapons too, if possible,” to which WADS replies: “Yep, ok. We will do that.” [North American Aerospace Defense Command, 9/11/2001] The three F-16s launched from Langley Air Force Base at 9:30 (see (9:25 a.m.-9:30 a.m.) September 11, 2001) are in fact from the North Dakota Air National Guard’s 119th Fighter Wing, which, though based at Fargo, ND, has had a detachment of two F-16s on alert at Langley since late 2000. However, these are under the command of NEADS, not WADS. [Virginian-Pilot, 9/22/2001; New York Times, 10/16/2001; McChord Air Museum, 2007] It is therefore not clear what specific fighters are now being referred to when Nasypany speaks of the “aircraft out of Fargo,” nor is it clear if and when these planes are launched. Colonel John Cromwell, the commander of WADS, will later recall that he calls every fighter wing commander west of the Mississippi, and by midday (3:00 p.m. ET) has more than 100 fighter jets on alert.

The pilots that took off from Langley Air Force Base (see (9:25 a.m.-9:30 a.m.) September 11, 2001) hear a warning over radio that errant aircraft will be shot down, and receive an instruction from the Secret Service to protect the White House. [Spencer, 2008, pp. 222-223]
Pilots Learn of FAA Order - The three Langley fighter jets have now reached the Baltimore-Washington area. [Spencer, 2008, pp. 222] The pilots hear over their radios that the FAA has ordered all civilian aircraft to land. [New York Times, 10/16/2001] (The FAA issued this instruction at around 9:45 a.m. (see (9:45 a.m.) September 11, 2001). [US Congress. House. Committee On Transportation And Infrastructure, 9/21/2001; 9/11 Commission, 7/24/2004, pp. 29] )
Borgstrom Hears Shootdown Warning - The three pilots are all on different radio frequencies, but are able to communicate between themselves on their auxiliary frequency. According to author Lynn Spencer, one of them, Captain Craig Borgstrom, hears a message over the emergency radio frequency that is in response to the FAA’s recent order: “Attention all aircraft! Attention all aircraft! You are ordered to land at the nearest suitable airport. All aircraft must land immediately. Violators will be shot down.” The source of this message is unstated. [Filson, 2003, pp. 66; Spencer, 2008, pp. 222-223] (Author Leslie Filson will describe the Langley pilots hearing what is apparently a separate but similar message later on, some time after 10:42 a.m. (see 10:05 a.m.-11:05 a.m. September 11, 2001). [Filson, 2003, pp. 82] )
Instructed to Protect the White House - Around the time Borgstrom hears this, Major Dean Eckmann, the lead Langley pilot, is on the radio with the FAA’s Washington Center. A Secret Service agent has arrived there and wants to talk to him. [Filson, 2003, pp. 68; Spencer, 2008, pp. 222-223] Eckmann then receives a garbled message over his radio, which is difficult to make out. [New York Times, 11/15/2001] The message is, “Protect the house.” Eckmann will later recall, “I took it to mean protect the White House.” [Filson, 2003, pp. 68] He notifies the two other pilots—Borgstrom and Major Brad Derrig—of this message. He tells them, “I think I just talked to the Secret Service, but I’m not sure.” [New York Times, 11/15/2001]
Possible Shootdown Order? - According to Spencer, this message means that “Unknown to NEADS” (NORAD’s Northeast Air Defense Sector), Eckmann has been “given shootdown authority directly from the Secret Service, bypassing the military chain of command.” [Spencer, 2008, pp. 223] But Borgstrom and Derrig will later say they “never received explicit orders to fire on incoming planes perceived to be hostile.” [New York Times, 11/15/2001] Borgstrom radios NEADS weapons director Steve Citino and asks for specific instructions about what to do (see 10:07 a.m. September 11, 2001). [Spencer, 2008, pp. 223] According to the 9/11 Commission, NEADS will only learn that NORAD has been given clearance to shoot down threatening aircraft at 10:31 a.m., and even then it does not pass this order along to the fighter pilots under its command (see 10:31 a.m. September 11, 2001).

United Airlines official Sandy Rogers calls Ellen King at the FAA’s Command Center to discuss Flight 93. The timing of the call is not known specifically, although it appears to be after the Pentagon was hit and could not be long after Flight 93 is thought to have crashed, which is shortly after 10:00 a.m. (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001). Rogers tells King that Flight 93 has been hijacked, and King responds, “Oh God… thank you,” indicating she was previously unaware of the hijacking. However, the FAA had been aware of the situation since a few minutes after the hijacking took place (see (9:33 a.m.) September 11, 2001 and 9:34 a.m. September 11, 2001). Rogers also says: “It’s over Hagerstown now and you’re not aware of it. It’s heading toward Washington, DC, and we are under a threat of a hijacking on board and this flight is out of our control now heading toward Washington, DC.” Rogers states that United Airlines is “advising the military” about the plane and King also says that the FAA will do the same. [Federal Aviation Administration, 10/14/2003, pp. 37-39 pdf file] However, there are no other reports of Flight 93 ever being over Hagerstown, which is in Maryland. Flight 93 is said to crash in Shanksville, Pennsylvania, and is thought never to reach Maryland. There will be some—apparently mistaken—reports that the plane is still airborne after it is thought to have crashed (see (Between 10:10 a.m. and 10:15 a.m.) September 11, 2001 and 10:10 a.m.-10:11 a.m. September 11, 2001), and this may be another such report.

According to the 9/11 Commission, the NMCC learns about the Flight 93 hijacking at this time. Since the FAA has not yet been patched in to the NMCC’s conference call, the news comes from the White House. The White House learned about it from the Secret Service, and the Secret Service learned about it from the FAA. NORAD apparently is still unaware. Four minutes later, a NORAD representative on the conference call states, “NORAD has no indication of a hijack heading to Washington, D.C., at this time.” [9/11 Commission, 6/17/2004]

The military liaison at the FAA’s Cleveland Center calls NORAD’s Northeast Air Defense Sector (NEADS) and alerts it to the hijacked Flight 93. According to the 9/11 Commission, this is the first notification NEADS receives about Flight 93, but it comes too late, since the plane has already crashed (see (10:06 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 30; 9/11 Commission, 8/26/2004, pp. 46]
'Bomb on Board' Flight 93 - At 10:05 a.m., the military liaison at the Cleveland Center, who is unaware that Flight 93 has just crashed, calls NEADS to inform it that Flight 93 is heading toward Washington, DC. Even though communicating with NEADS is not one of his responsibilities, he wants to make sure it is in the loop. [Spencer, 2008, pp. 224] At NEADS, the call is answered by Tech Sergeant Shelley Watson. Shortly into the call, at 10:07, the military liaison tells her: “We got a United 93 out here. Are you aware of that?” He continues, “That has a bomb on board.” Watson asks: “A bomb on board? And this is confirmed? You have a mode three [beacon code], sir?” The military liaison replies, “No, we lost his transponder” (see (9:40 a.m.) September 11, 2001). The news about Flight 93 is shouted out to Major Kevin Nasypany, the NEADS mission crew commander. Nasypany responds: “Gimme the call sign. Gimme the whole nine yards.… Let’s get some info, real quick. They got a bomb?”
Liaison Wants Fighters Sent toward Flight 93 - The military liaison continues, asking Watson if NEADS scrambled fighter jets in response to Delta 1989, an aircraft that was mistakenly reported as having been hijacked (see (9:28 a.m.-9:33 a.m.) September 11, 2001 and 9:39 a.m. September 11, 2001). Watson replies: “We did. Out of Selfridge and Toledo” (see (9:55 a.m.) September 11, 2001 and 10:01 a.m. September 11, 2001), and says these jets are airborne. When the military liaison asks if the fighters can be directed to where Flight 93 is, Watson asks him if the Cleveland Center has latitude and longitude coordinates for this aircraft. The military liaison replies that he has not got this information available right now. All he knows is that Flight 93 has “got a confirmed bomb on board… and right now, his last known position was in the Westmoreland area.… Which is… in the Pittsburgh, Pennsylvania, area.” [North American Aerospace Defense Command, 9/11/2001; Vanity Fair, 8/1/2006]
NEADS Searches on Radar - The news of a bomb on board Flight 93 spreads quickly at NEADS, and personnel there search for the aircraft’s primary return on their radar screens. But because the plane has already crashed, they will be unable to locate it. NEADS will only learn that Flight 93 has crashed at 10:15 a.m., during a call with the FAA’s Washington Center (see 10:15 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 30-31]
FAA Failed to Notify Military Earlier - The Cleveland Center’s notification to NEADS about Flight 93 comes 39 minutes after the plane was hijacked (see (9:28 a.m.) September 11, 2001) and 33 minutes after FAA headquarters was alerted to the hijacking (see 9:34 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 11, 28] At the time NEADS is alerted to Flight 93, NORAD is similarly uninformed about this aircraft, according to the 9/11 Commission. The Commission will state, “At 10:07, its representative on the air threat conference call stated that NORAD had ‘no indication of a hijack heading to DC at this time.’” According to the Commission, the National Military Command Center (NMCC) at the Pentagon learned about the Flight 93 hijacking slightly earlier on, at 10:03 a.m. (see 10:03 a.m. September 11, 2001). However, the NMCC was notified by the White House, not the FAA. [9/11 Commission, 7/24/2004, pp. 42] A former senior FAA executive, speaking on condition of anonymity, will later try to explain why it takes the FAA so long to alert NEADS to Flight 93. He will say, “Our whole procedures prior to 9/11 were that you turned everything [regarding a hijacking] over to the FBI.” [Vanity Fair, 8/1/2006] Yet military instructions contradict this, stating, “In the event of a hijacking, the NMCC will be notified by the most expeditious means by the FAA.” [US Department of Defense, 7/31/1997 pdf file; US Department of Defense, 6/1/2001 pdf file]
NORAD Commanders Claim Earlier Awareness of Flight 93 - Two senior NORAD officials will contradict the 9/11 Commission’s conclusion, and claim they were aware of Flight 93 well before it crashed (see Shortly Before 9:36 a.m. September 11, 2001 and (9:36 a.m.-10:06 a.m.) September 11, 2001). [Filson, 2003, pp. 68, 71-73] Colonel Robert Marr, the NEADS battle commander, will tell the Commission that, while the flight was still airborne, “his focus was on UAL 93, which was circling over Chicago,” and he “distinctly remembers watching the flight UAL 93 come west, and turn over Cleveland.” [9/11 Commission, 10/27/2003 pdf file; 9/11 Commission, 1/23/2004 pdf file] Major General Larry Arnold, the commander of the Continental US NORAD Region, will recall, “[W]e watched the [Flight] 93 track as it meandered around the Ohio-Pennsylvania area and started to turn south toward DC.” [Filson, 2003, pp. 71]

[Vanity Fair, 8/1/2006]
Borgstrom Wants Instructions - The three F-16s that took off from Langley Air Force Base are now flying in the Baltimore-Washington area. They have just heard a warning over the radio that errant aircraft will be shot down, and received an instruction from the Secret Service to protect the White House (see (10:00 a.m.) September 11, 2001). The FAA’s Washington Center also notified them of a suspicious aircraft flying at high speed toward the White House. In response, pilot Craig Borgstrom radios NEADS and asks weapons director Steve Citino for instructions on what to do. [Spencer, 2008, pp. 222-223] Borgstrom says: “Baltimore [the Washington Center] is saying something about an aircraft over the White House. Any words?” Citino replies: “Negative. Stand by,” and then relays Borgstrom’s message to Major James Fox, the leader of the NEADS weapons team. Fox then notifies Major Kevin Nasypany, the NEADS mission crew commander, of the aircraft over the White House.
Ordered to Intercept - Instinctively, Nasypany responds, “Intercept!” and he then elaborates, “Intercept and divert that aircraft away from there.” Citino passes this instruction to the Langley fighters, telling them their mission is to “intercept aircraft over White House. Use FAA for guidance.” Fox then adds: “Divert the aircraft away from the White House. Intercept and divert it.” Borgstrom confirms the order, saying, “Divert the aircraft.”
Unidentified Aircraft a False Alarm - As the F-16s head for the White House, the NEADS controllers are unable to find the building on their dated equipment, and also have trouble communicating with the Langley pilots. NEADS personnel speculate that the unidentified object is probably just a helicopter or smoke from the burning Pentagon. Minutes later, the suspect aircraft will be realized to probably be one of the Langley fighters, mistakenly reported by a Washington Center air traffic controller who was unaware of the military’s scrambles. Citino will comment: “That was cool. We intercepted our own guys.” [North American Aerospace Defense Command, 9/11/2001; Vanity Fair, 8/1/2006]

Two senior NORAD officials, Colonel Robert Marr and Major General Larry Arnold, have to address the possibility of issuing shootdown authorization to fighter jets under their command, after a report is received about an aircraft over the White House. [Spencer, 2008, pp. 224-225]
Aircraft over White House - Marr, the battle commander at NORAD’s Northeast Air Defense Sector (NEADS) in Rome, New York, is in the NEADS battle cab. On the NEADS operations floor, mission crew commander Major Kevin Nasypany has just learned of a report of an aircraft flying over the White House (see 10:07 a.m. September 11, 2001), and now talks to Marr over the phone. Nasypany asks: “Okay, did you hear that? Aircraft over the White House. What’s the word? Intercept and what else?” Marr has a phone to each ear and does not hear what Nasypany says. Nasypany therefore repeats, “Aircraft… over… the White House!” pausing on each word for emphasis. [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 224]
Commanders Discuss Shootdown Order - The news of an aircraft over the White House forces Marr and Arnold, with whom he has been communicating, to address the issue of authorizing the shooting down of aircraft. [Spencer, 2008, pp. 225] Arnold, the commander of NORAD’s Continental US Region (CONR), is at the CONR air operations center at Tyndall Air Force Base in Florida. [Code One Magazine, 1/2002] According to author Lynn Spencer, he has not yet received any instructions from his higher-ups regarding shootdown authorization. “He talked to Major General Rick Findley,” who is at NORAD’s operations center in Colorado, “and asked him to get shootdown authority from the vice president, but he’s still heard nothing back.” [Spencer, 2008, pp. 225]
Arnold Possibly Authorizes Shootdown - Arnold will later tell author Leslie Filson that he has “the authority in case of an emergency to declare a target hostile and shoot it down under an emergency condition.” [Filson, 2003, pp. 75] But according to Vanity Fair, he only passes the current request for rules of engagement further up his chain of command. [Vanity Fair, 8/1/2006] However, Spencer will claim otherwise, stating, “In light of the imminent attack on the White House,” Arnold “decides he will exercise the authority he has to protect the nation in an emergency.” He tells Marr: “We will intercept and attempt to divert. If we can’t, then we’ll shoot it down.” [Spencer, 2008, pp. 225]
Alleged Shootdown Authorization Not Passed On - Minutes later, though, Nasypany will tell his staff that the pilots that took off from Langley Air Force Base (see (9:25 a.m.-9:30 a.m.) September 11, 2001) have “negative clearance to shoot” aircraft over Washington (see 10:10 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 31] And according to the 9/11 Commission, NEADS only learns that NORAD has been given clearance to shoot down threatening aircraft at 10:31 a.m., and even then it does not pass this order along to the fighter pilots under its command (see 10:31 a.m. September 11, 2001).

Lewis ‘Scooter’ Libby. [Source: David Bohrer / White House] (click image to enlarge)The Secret Service, viewing projected path information about Flight 93, rather than actual radar returns, does not realize that Flight 93 has already crashed. Based on this erroneous information, a military aide tells Vice President Dick Cheney and others in the White House bunker that the plane is 80 miles away from Washington. Cheney is asked for authority to engage the plane, and he quickly provides it. The aide returns a few minutes later and says the plane is 60 miles out. Cheney again gives authorization to engage. A few minutes later and presumably after the flight has crashed or been shot down, deputy White House chief of staff Josh Bolten suggests Cheney contact President Bush to confirm the engage order. Bolten later tells the 9/11 Commission that he had not heard any prior discussion on the topic with Bush, and wanted to make sure Bush knew. Apparently, Cheney calls Bush and obtains confirmation (see 10:18 a.m.-10:20 a.m. September 11, 2001). [9/11 Commission, 6/17/2004] However, there is controversy over whether Bush approved a shootdown before this incident or whether Cheney gave himself the authority to make the decision on the spot. As Newsweek notes, it is a moot point in one sense, since the decision was made on false data and there is no plane to shoot down. [Newsweek, 6/20/2004]

A weapons director at NORAD’s Northeast Air Defense Sector (NEADS) informs the fighter jets launched from Langley Air Force Base (see (9:25 a.m.-9:30 a.m.) September 11, 2001) that they do not have permission to shoot down aircraft over Washington, though he is delayed in giving this instruction due to communications problems. [North American Aerospace Defense Command, 9/11/2001; 9/11 Commission, 6/17/2003; 9/11 Commission, 7/24/2004, pp. 45; Vanity Fair, 8/1/2006; Spencer, 2008, pp. 227]
Citino Cannot Reach Borgstrom - Major Kevin Nasypany, the NEADS mission crew commander, has just told his staff that the Langley fighters have “negative clearance to shoot,” and the orders from higher headquarters are that the jets are to identify aircraft by their type and tail number, and nothing more (see 10:10 a.m. September 11, 2001). Now Master Sergeant Steve Citino, a NEADS weapons director, tries relaying these instructions to Captain Craig Borgstrom, one of the three Langley pilots. However, he cannot get through to him over the radio. According to author Lynn Spencer, this is because the “reception is weak over the Washington area, and NEADS loses the ability to communicate whenever [Borgstrom] flies below a certain altitude.” Citino complains to Major James Fox, the leader of the weapons team: “I can’t talk to ‘em. They’re too low.” [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 227]
Citino Issues Instructions - Finally, about a minute after receiving the instructions from Nasypany, Citino reaches Borgstrom. He tells him, “Reiterating, mission is ID by type… divert if necessary.” Borgstrom acknowledges this instruction, telling Citino, “Quit 2-6 copies.” [North American Aerospace Defense Command, 9/11/2001; 9/11 Commission, 6/17/2003] When two of the Langley pilots later discuss this day’s events at a news conference, they will say they “never received explicit orders to fire on incoming planes perceived to be hostile.” [New York Times, 11/15/2001]

Someone from the 174th Fighter Wing, which is based at Hancock Field Air National Guard Base near Syracuse, NY, calls NORAD’s Northeast Air Defense Sector (NEADS) and speaks with Major Kevin Nasypany, the mission crew commander there. [North American Aerospace Defense Command, 9/11/2001] Earlier on, shortly after seeing the second plane hitting the World Trade Center at 9:03, a commander of the 174th Fighter Wing called NEADS to offer fighter jets to help (see (After 9:03 a.m.) September 11, 2001). They’d said: “Give me ten [minutes] and I can give you hot guns. Give me 30 [minutes] and I’ll have heat-seeker [missiles]. Give me an hour and I can give you slammers.” [Aviation Week and Space Technology, 6/3/2002; News 10 Now, 9/12/2006] Yet, now, more than an hour after the second attack, these fighters have still not been launched. Syracuse tells Nasypany, “I’ve got guys that’ll be launching in about 15 minutes.” Despite the earlier promise to have heat-seekers and slammers on the planes, Syracuse says: “We’ve got hot guns. That’s all I’ve got.” Nasypany says: “I’ve got another possible aircraft with a bomb on board. It’s in Pennsylvania, York, approximate area.” He adds that there is “another one, that’s possibly at Cleveland area.” These aircraft, he says, are United Airlines Flight 93 and Delta ‘89, respectively. (Although Flight 93 has already crashed, NEADS apparently does not learn of this until 10:15 (see 10:15 a.m. September 11, 2001).) NEADS was alerted to Delta Flight 1989 at 9:41, and mistakenly suspects it has been hijacked (see 9:39 a.m. September 11, 2001). Syracuse says: “I’ve got two jets right now. Do you need more than two?” After NEADS requests another two, Syracuse replies, “Get four set up, yep.” [North American Aerospace Defense Command, 9/11/2001] According to the Syracuse Post-Standard, the first fighters to launch from Hancock Field are two F-16s that take off at 10:42 a.m. A further three take off at about 1:30 p.m., and two more launch around 3:55 p.m. (see 10:42 a.m. September 11, 2001).

A lieutenant colonel at the White House repeatedly relays to the National Military Command Center (NMCC) at the Pentagon that Vice President Dick Cheney has confirmed that fighter jets are cleared to engage an inbound aircraft if they can verify that the aircraft is hijacked. The lieutenant colonel notifies the NMCC of the authorization over the air threat conference call (see 9:29 a.m.-9:34 a.m. September 11, 2001). Cheney, who is in the Presidential Emergency Operations Center (PEOC) below the White House, said at sometime between 10:10 and 10:15 that fighters could engage an aircraft that was reportedly approaching Washington (see (Between 10:10 a.m. and 10:15 a.m.) September 11, 2001). However, it is only when Cheney calls President Bush at 10:18 a.m. that Bush confirms the shootdown order (see 10:18 a.m.-10:20 a.m. September 11, 2001). The shootdown order will be received by NORAD, and then, at 10:31 a.m., sent out to its three air defense sectors in the continental US (see 10:31 a.m. September 11, 2001).

According to the 9/11 Commission, NEADS calls Washington flight control at this time. Asked about Flight 93, flight control responds, “He’s down.” It is clarified that the plane crashed “somewhere up northeast of Camp David.… That’s the last report. They don’t know exactly where.” [9/11 Commission, 6/17/2004] The crash site is in fact about 85 miles northwest of Camp David. [Associated Press, 9/11/2001]

A representative of the FAA finally joins an emergency teleconference being conducted by the National Military Command Center (NMCC) at the Pentagon, after NMCC personnel have repeatedly been unable to connect the FAA to the conference. In response to the terrorist attacks, the NMCC began a “significant event conference” at 9:29 a.m., to gather and disseminate information from government agencies (see 9:29 a.m.-9:34 a.m. September 11, 2001), and eight minutes later upgraded this to an “air threat conference” (see 9:37 a.m.-9:39 a.m. September 11, 2001). However, according to the 9/11 Commission Report, because of “equipment problems and difficulty finding secure phone numbers,” operators at the NMCC have been unable to connect the FAA to the conference (see (9:29 a.m.-12:00 p.m.) September 11, 2001). [9/11 Commission, 7/21/2003 pdf file; 9/11 Commission, 7/24/2004, pp. 37]
FAA Representative Has 'No Situational Awareness' - The air threat conference is now joined by FAA employee Rayford Brooks. [9/11 Commission, 7/24/2004, pp. 463] Brooks is on duty in the Central Altitude Reservation Function (CARF) at the FAA’s Command Center in Herndon, Virginia. This office is responsible for processing and separating altitude reservations, and coordinates military requests for priority airspace activity with FAA facilities and international agencies. [9/11 Commission, 4/5/2004; 9/11 Commission, 4/15/2004] However, Brooks has “no familiarity with or responsibility for hijackings, no access to decisionmakers, and none of the information available to senior FAA officials,” according to the 9/11 Commission Report. [9/11 Commission, 7/24/2004, pp. 37] Brooks will later recall having had “no situational awareness” of the current crisis. He only arrived at the Command Center at around 9:30 a.m. and had not been listening to the radio while driving to work. Those on the Command Center floor have not given him any instructions regarding the NMCC conference or other operational matters.
Brooks on Conference instead of Military Cell Officer - Brooks will tell the 9/11 Commission that the Air Traffic Services Cell (ATSC)—a small office located next to the CARF at the Command Center, manned by military reservists (see (Between 9:04 a.m. and 9:25 a.m.) September 11, 2001)—has asked the CARF to monitor the NMCC’s air threat conference on its behalf for three or four hours, because the ATSC does not have a working STU-III secure phone. [9/11 Commission, 4/15/2004] (A chronology of the ATSC’s actions on this day will state that the keys for the ATSC’s secure phones are recalibrated at some point, and these phones then “worked fine.” [US Air Force, 9/11/2001] )
NORAD and FAA Leaders out of Contact - Three times before 10:03 a.m., when the last hijacked plane reportedly crashed (see (10:03 a.m.-10:10 a.m.) September 11, 2001), NORAD asked for confirmation of the FAA’s presence on the NMCC’s conference, so the FAA could provide an update on the hijackings, but the FAA had not been connected at those times. As a result of the FAA’s absence from the conference, the leaders of NORAD and the FAA have effectively been out of contact with each other. [9/11 Commission, 6/17/2004; 9/11 Commission, 7/24/2004, pp. 37-38]
FAA's Absence Caused Confusion over Identities of Hijacked Planes - General Richard Myers, the acting chairman of the Joint Chiefs of Staff, will later write that the lack of communication between the NMCC and the FAA has contributed to confusion at the NMCC over the flight numbers of the aircraft that were hijacked. However, according to Myers, the NMCC could not contact the FAA over ordinary phone lines because “[t]errorists who could hijack aircraft so readily could probably also eavesdrop on unsecured phone lines.” [Myers, 2009, pp. 153]

An aircraft at Cleveland Hopkins International Airport.An aircraft at Cleveland Hopkins International Airport. [Source: Cleveland Plain Dealer]Delta Air Lines Flight 1989, a Boeing 767 out of Boston that is wrongly suspected of being hijacked (see 9:39 a.m. September 11, 2001 and (Shortly After 9:44 a.m.) September 11, 2001), lands at Cleveland Hopkins Airport in Ohio, and is directed to a remote area of the airport. [Federal Aviation Administration, 9/16/2001; USA Today, 8/13/2002; 9/11 Commission, 7/24/2004, pp. 27-28; WKYC, 9/11/2006]
Plane Flies Long Path toward Airport - Delta Air Lines had been concerned about Flight 1989, and ordered it to land as soon as possible in Cleveland (see (9:42 a.m.) September 11, 2001). [Spencer, 2008, pp. 167; USA Today, 9/11/2008] As it was heading in to land, air traffic controllers instructed Delta 1989 to follow a trajectory that initially took it far past Cleveland Airport. Unknown to the plane’s pilots, the controllers incorrectly believe the flight has been hijacked and contains a bomb, and they were therefore making time to evacuate the airport before the plane landed (see (9:50 a.m. and After) September 11, 2001). [Spencer, 2008, pp. 191]
Plane Directed to Remote Area - Once Delta 1989 is on the ground, the Cleveland Terminal Radar Approach Control (TRACON) informs the FAA’s Cleveland Center that Delta 1989 is “on the ground at 1418,” where “1418” means 10:18 a.m. Cleveland Center asks, “Very safely too, I hope?” The TRACON responds that the plane is being taken to the bomb area to check. [Federal Aviation Administration, 9/16/2001] Delta 1989 is directed to “taxi left onto taxiway Bravo and wait there.” This taxiway leads to a remote part of the airport that is far away from the terminal. The pilot does as instructed. [Spencer, 2008, pp. 229]
Passengers Not Allowed Off - The pilots radio the airport’s air traffic control tower and say: “Just to make sure we don’t have any misunderstandings here, our flaps are up, we are landing only as a precaution at the company’s request. You understand that?” They ask if they are going to get to their gate soon, but the controller responds that city authorities are in charge and he believes people will be coming to search the aircraft. The controller advises that city authorities have said to keep the plane’s passengers on the aircraft for now. [Federal Aviation Administration, 9/16/2001] The passengers and crew will have to remain on board for perhaps a couple of hours, until FBI agents allow them off (see 11:28 a.m.-12:23 p.m. September 11, 2001). [WKYC, 9/11/2006; Spencer, 2008, pp. 270-271]
Conflicting Reports of Landing Time - Subsequent accounts will give conflicting times for when Delta 1989 lands at Cleveland Airport. According to a detailed timeline provided by the airport’s control tower, the aircraft is “on the ground” at 10:18 a.m. [Federal Aviation Administration, 9/16/2001] Several accounts will give similar landing times of between 10:05 a.m. and 10:10 a.m. [Federal Aviation Administration, 1/2/2002; USA Today, 8/13/2002] But a NORAD official will tell the 9/11 Commission that Delta 1989 landed at 9:47 a.m. [9/11 Commission, 5/23/2003] Other accounts will say it lands at between 10:33 a.m. and 10:45 a.m. [Associated Press, 9/11/2001; Associated Press, 9/11/2001; Federal Aviation Administration, 9/17/2001 pdf file]

Patrick Madigan, the commander of the Somerset Barracks of the Pennsylvania State Police, arrives at the Flight 93 crash scene around 10:20 a.m. [Department of the Army and the Air Force National Guard Bureau, 2002 pdf file] He says that at some point later in the day (he does not specify a time), a “strange incident” occurs: “We were there at the site and an airplane started circling. It was a jetliner circling the crash site very low. No one knew what to expect because we knew that all of the planes were supposedly grounded.” (The FAA had, at about 9:45 a.m., ordered that all aircraft be instructed to land at the nearest airport (see (9:45 a.m.) September 11, 2001).) After a few minutes of uncertainty, it is announced that the plane is carrying United Airlines executives, who are circling the site to view it before they land in nearby Johnstown. [Kashurba, 2002, pp. 63] Another low-flying jet plane was witnessed over the site earlier on, around the time Flight 93 went down (see (Before and After 10:06 a.m.) September 11, 2001).
