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

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

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.

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

NORAD’s war room in Cheyenne Mountain, ColoradoNORAD’s war room in Cheyenne Mountain, Colorado [Source: Val Gempis]Lieutenant Colonel Dawne Deskins and other day shift employees at NORAD’s Northeast Air Defense Sector (NEADS) in Rome, NY, start their workday. NORAD is conducting a week-long, large-scale exercise called Vigilant Guardian. [Newhouse News Service, 1/25/2002] Deskins is regional mission crew chief for the Vigilant Guardian exercise. [ABC News, 9/11/2002]
Exercise Includes Simulated Attack on the US - Vigilant Guardian is described as “an exercise that would pose an imaginary crisis to North American Air Defense outposts nationwide”; as a “simulated air war”; and as “an air defense exercise simulating an attack on the United States.” According to the 9/11 Commission, it “postulated a bomber attack from the former Soviet Union.” [Newhouse News Service, 1/25/2002; Filson, 2003, pp. 55 and 122; 9/11 Commission, 7/24/2004, pp. 458] Vigilant Guardian is described as being held annually, and is one of NORAD’s four major annual exercises. [Filson, 2003, pp. 41; Arkin, 2005, pp. 545; GlobalSecurity (.org), 4/27/2005] However, one report says it takes place semi-annually. [Aviation Week and Space Technology, 6/3/2002] Accounts by participants vary on whether 9/11 is the second, third, or fourth day of the exercise. [Code One Magazine, 1/2002; Newhouse News Service, 1/25/2002; Ottawa Citizen, 9/11/2002] Vigilant Guardian is a command post exercise (CPX), and in at least some previous years was conducted in conjunction with Stratcom’s Global Guardian exercise and a US Space Command exercise called Apollo Guardian. [US Congress, n.d.; Arkin, 2005, pp. 545; GlobalSecurity (.org), 4/27/2005] All of NORAD is participating in Vigilant Guardian on 9/11. [Aviation Week and Space Technology, 6/3/2002]
Exercise Includes Simulated Hijacking - Vanity Fair reports that the “day’s exercise” (presumably Vigilant Guardian) is “designed to run a range of scenarios, including a ‘traditional’ simulated hijack in which politically motivated perpetrators commandeer an aircraft, land on a Cuba-like island, and seek asylum.” [Vanity Fair, 8/1/2006] However, at NEADS, most of the dozen or so staff on the operations floor have no idea what the exercise is going to entail and are ready for anything. [Utica Observer-Dispatch, 8/5/2004]
NORAD Fully Staffed and Alert - NORAD is currently running a real-world operation named Operation Northern Vigilance (see September 9, 2001). It may also be conducting a field training exercise calling Amalgam Warrior on this morning (see 9:28 a.m. September 11, 2001). NORAD is thus fully staffed and alert, and senior officers are manning stations throughout the US. The entire chain of command will be in place and ready when the first hijacking is reported. An article later says, “In retrospect, the exercise would prove to be a serendipitous enabler of a rapid military response to terrorist attacks on September 11.” [Aviation Week and Space Technology, 6/3/2002; Bergen Record, 12/5/2003] Colonel Robert Marr, in charge of NEADS, will say: “We had the fighters with a little more gas on board. A few more weapons on board.” [ABC News, 9/11/2002] However, Deskins and other NORAD officials later are initially confused about whether the 9/11 attacks are real or part of the exercise (see (8:38 a.m.-8:43 a.m.) September 11, 2001).

Jeff Ford.Jeff Ford. [Source: Thomas Doscher / US Air Force]Personnel in NORAD’s operations center in Cheyenne Mountain, Colorado, take part in a major Cold War-style training exercise called Vigilant Guardian, a war game in which the theoretical enemy is Russia. [9/11 Commission, 3/1/2004 pdf file; Denver Post, 8/28/2011; Colorado Springs Gazette, 9/10/2011] All of NORAD, including its subordinate units (see (6:30 a.m.) September 11, 2001), participates in the exercise. [Northeast Air Defense Sector, 8/23/2001; Canadian Broadcasting Corporation, 9/8/2011] More than 50 people in the NORAD Battle Management Center in Cheyenne Mountain take part. [Airman, 3/2002; Defense Video and Imagery Distribution System, 9/8/2011] Vigilant Guardian is an annual exercise and is scheduled to last two weeks. [Arkin, 2005, pp. 545; Canadian Broadcasting Corporation, 9/8/2011] It has been underway for several days. Those in the Cheyenne Mountain Operations Center (CMOC) have been participating in it “for at least three or four days,” according to Lieutenant Colonel Steven Armstrong, NORAD’s chief of plans and forces. [North American Aerospace Defense Command, 9/9/2011]
Vigilant Guardian Is a 'Full-Blown Nuclear War' Exercise - Vigilant Guardian is a “transition to wartime operations command post exercise,” according to an information page for its participants. [Northeast Air Defense Sector, 8/23/2001] The 1st Air Force’s book about 9/11 will describe it as a “simulated air war.” [Filson, 2003, pp. 55] Lieutenant Colonel William Glover, the commander of NORAD’s Air Warning Center, will later recall that it involves NORAD “simulating war.… You know, attacks coming from the outside, Soviet-style bombers coming in, cruise-missile attacks, that type of thing.” [Canadian Broadcasting Corporation, 9/8/2011] Ken Merchant, NORAD’s joint exercise design manager, will tell the 9/11 Commission that Vigilant Guardian is a “full-blown nuclear war” exercise, and includes bomber response and intercontinental ballistic missile response. [9/11 Commission, 3/4/2004]
Russia Is Imagined Enemy - The theoretical enemy in the exercise is Russia. [Denver Post, 8/28/2011] According to the 9/11 Commission Report, the exercise “postulated a bomber attack from the former Soviet Union.” [9/11 Commission, 7/24/2004, pp. 458] Merchant will explain that “NORAD must use Russia in its exercises at the strategic level since no other country poses a great enough threat to NORAD’s capabilities and responsibilities.” [9/11 Commission, 3/4/2004]
Personnel Updated on Exercise during Shift Change - Armstrong will later recall that today starts off “like any other day. We came in thinking it would be a normal day… we did a standard shift changeover in the morning and we were getting right into where we were at in relation to the exercise.” He will describe that in a shift change during the exercise, “We’d say, ‘Okay, here’s what happened during the night shift (or the day shift),’ and we’d give each other an update, and then we’d start planning for whatever was on the agenda for that day.” [North American Aerospace Defense Command, 9/9/2011] According to the Denver Post, after commencing his shift, Armstrong “mapped out strategy in a chess game of ever-escalating scenarios, from strained diplomacy to the outbreak of conventional warfare that headed inexorably toward nuclear conflict” with Russia.

B-1 Bomber Scheduled to Fly out over Pacific Ocean - The “planned big event for the day” in the exercise is “supposed to be a B-1 bomber that was flying out of Fairchild Air Force Base [in Washington State] and going out over the Pacific,” according to Jeff Ford, an Air Force lieutenant colonel who is working in the CMOC. Ford will add that there are “other things going on as part of the exercise, air exercise events, and then some scripted inputs that we were reacting to there in the Air Warning Center, whether it be unknown aircraft that we scramble aircraft for to intercept—or whatever.” [Defense Video and Imagery Distribution System, 9/8/2011]
Exercise Posture Allegedly Helps Response to Attacks - Vigilant Guardian will reportedly end after 9:03 a.m., when the second plane hits the World Trade Center (see (Shortly After 9:03 a.m.) September 11, 2001), and the CMOC personnel participating in it will then become involved in responding to the real-world attacks. [Airman, 3/2002; Toronto Star, 11/11/2008] Glover will claim that the CMOC’s response to the terrorist attacks benefits from the position the operations center is in for the exercise. He will say NORAD is “lucky” because “all the directorates such as operations, logistics, security, all those folks were up in the [Cheyenne] Mountain on an exercise posture.” He will add that “these are the same folks that we would bring up in case of contingencies or in time of going to war. So, in reality, I had all the guys up into the NORAD Battle Management Center that I needed to conduct the exercise as well as the contingency operations that happened on 9/11.” [Defense Video and Imagery Distribution System, 9/8/2011]
NORAD Monitoring Russian Exercise - NORAD was created in 1958, during the Cold War, to protect North American airspace against nuclear attacks from the Soviet Union. [New York Times, 4/25/2004; Canadian Broadcasting Corporation, 8/6/2004; Legion Magazine, 11/2004] According to the Toronto Star, “Whether it’s a simulation or a real-world event, the role of the [CMOC] is to fuse every critical piece of information NORAD has into a concise and crystalline snapshot.” [Toronto Star, 12/9/2001] As well as the Vigilant Guardian exercise, NORAD is currently in the middle of an operation called Northern Vigilance, with its fighter jets deployed to Alaska and Northern Canada to monitor an exercise being run by the Russian Air Force (see September 9, 2001).

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]

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

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

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).

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

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

[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]

The air traffic control tower at Otis Air National Guard Base.The air traffic control tower at Otis Air National Guard Base. [Source: CapeCodFD.com]Daniel Bueno, a supervisor at the FAA’s Boston Center, calls the air traffic control tower at Otis Air National Guard Base to alert it to the problems with Flight 11 and request military assistance. [Filson, 2003, pp. 47; Spencer, 2008, pp. 22] Otis Air Base, at Cape Cod, Massachusetts, is one of NORAD’s seven alert sites in the continental United States, which keeps two armed fighter jets ready for immediate takeoff. [Filson, 2003, pp. 50; 9/11 Commission, 7/24/2004, pp. 17]
Supervisor Calls Otis, Violating Protocol - Bueno calls the control tower at Otis even though, according to author Lynn Spencer, he “knows it’s not standard operating procedure to call the military directly—that’s supposed to be done by FAA headquarters.” But he has “checked the FAA regulation manual, and in the back under section FAAO 7610.4J, Appendix 16, it states that fighters can be launched directly at FAA request, so he is going to make that happen. He may not be FAA headquarters, but he is FAA!” [Spencer, 2008, pp. 22]
Bueno Requests Fighters, Told to Call NEADS - Bueno tells the controller at the Otis tower that Flight 11 has lost its identification signal and appears to be headed toward Manhattan; it looks like a possible hijacking, and fighter jets are needed, fast. [Filson, 2003, pp. 47] But the controller tells Bueno that he must follow the protocol, which is to contact NORAD’s Northeast Air Defense Sector (NEADS). The controller says: “You’ve got to go through the proper channels. They’re the only ones with the authority to initiate a scramble order.” [Spencer, 2008, pp. 22] Bueno asks the controller for the telephone number for NEADS. [102nd Fighter Wing, 2001] Following this call, the tower controller will contact the Otis Air Base operations desk, to let it know that it might be receiving a call from NEADS (see (Between 8:31 a.m. and 8:40 a.m.) September 11, 2001). [Spencer, 2008, pp. 27]
Otis Pilots Critical of Bueno - The two alert pilots at Otis Air Base will later criticize Bueno for calling the base directly. One of them, Major Daniel Nash, will complain: “It sounds like the FAA didn’t have their [act] together at all when they were calling the [Otis] tower.… To me, it sounded like there was someone who didn’t know what they were doing.” [Boston Globe, 9/11/2005] Lieutenant Colonel Timothy Duffy, the other alert pilot, will comment: “It didn’t happen the way it was supposed to.… We were the ones who were contacted right away and knew about it before the air defense sector.” [Filson, 2003, pp. 50]
Time of Call Unclear - Bueno also calls the FAA’s Cape Terminal Radar Approach Control (TRACON), which is located on Otis Air Base, at 8:34 a.m. and requests that fighters be launched from Otis (see 8:34 a.m. September 11, 2001). [Federal Aviation Administration, 4/19/2002; 9/11 Commission, 9/22/2003 pdf file] Whether he makes that call before or after he calls the Otis tower is unstated. According to the 9/11 Commission Report, “the first notification received by the military—at any level—that American 11 had been hijacked” is when the FAA’s Boston Center calls NEADS just before 8:38 a.m. (see (8:37 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] If that is correct, it would indicate that Bueno calls the Otis tower after he calls the Cape TRACON.

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

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

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

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

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]

Dave Bottiglia.Dave Bottiglia. [Source: ABC News]After Flight 11 appears on his radar screen, Dave Bottiglia, an air traffic controller at the FAA’s New York Center, is informed that this aircraft is suspected of having been hijacked. Flight 175 entered Bottiglia’s airspace not long before this (see 8:40 a.m. September 11, 2001). [MSNBC, 9/11/2002; 9/11 Commission, 8/26/2004, pp. 20] Its pilot has just told Bottiglia about the “suspicious transmission” (presumably from Flight 11) he heard while departing Boston airport (see 8:41 a.m.-8:42 a.m. September 11, 2001). [Gregor, 12/21/2001 pdf file] Seconds later, Flight 11 also enters the area Bottiglia is monitoring and its target appears on his radar screen. The controller sitting next to Bottiglia gets up and points to the radar blip. He says: “You see this target here? This is American 11. Boston Center thinks it’s a hijack.” Bottiglia will later recall that his initial thought about Flight 11, based on this information, is that the hijackers “were probably going to Cuba.” As its transponder has been turned off (see (Between 8:13 a.m. and 8:21 a.m.) September 11, 2001), he has no altitude information for Flight 11, but can tell from the radar scope that it appears to be descending. According to author Lynn Spencer: “Even without a transponder, controller radars calculate ground speed for all radar targets, and when a plane is descending, the ground speed decreases. The flight had been ‘grounding’ 600 knots, and now it has decreased to 320.” Bottiglia follows Flight 11’s target on his radar screen until it disappears over New York City. [MSNBC, 9/11/2002; Spencer, 2008, pp. 37] Because he is focused on Flight 11, Bottiglia will not notice when Flight 175’s transponder code changes at 8:47 (see 8:46 a.m.-8:47 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 21; 9/11 Commission, 8/26/2004, pp. 21] The New York Center was first notified of Flight 11’s hijacking at 8:25 a.m. (see 8:25 a.m. September 11, 2001), though this information was not passed on to Bottiglia.

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

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

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

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]

Stuart now informs Colonel Robert Marr, the battle commander at NEADS, of his efforts. He also directs a “Major Edick”—another intelligence officer at NEADS—to search the SIPRNET for information on the hijacking. However, Stuart will later say, Edick is unable to find any such information on the SIPRNET “that morning or afternoon.” [Northeast Air Defense Sector, 9/11/2001; 9/11 Commission, 10/30/2003 pdf file]

According to the 9/11 Commission, Dave Bottiglia, the air traffic controller handling Flight 175, only notices now that this flight’s transponder signal has changed (see 8:46 a.m.-8:47 a.m. September 11, 2001). Bottiglia asks Flight 175 to return to its proper transponder code. There is no response. Beginning at 8:52 a.m., he makes repeated attempts to contact it, but there is still no response. Bottiglia contacts another controller at 8:53 a.m., and says: “We may have a hijack. We have some problems over here right now.… I can’t get a hold of UAL 175 at all right now and I don’t know where he went to.” [New York Times, 10/16/2001; 9/11 Commission, 6/17/2004; Spencer, 2008, pp. 48] This account apparently conflicts with earlier accounts that claim NORAD’s Northeast Air Defense Sector (NEADS) was notified at 8:43 a.m. that Flight 175 had been hijacked (see 8:43 a.m. September 11, 2001).

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

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

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

United Airlines activates its crisis center, from where it will respond to the terrorist attacks. [9/11 Commission, 11/20/2003 pdf file; 9/11 Commission, 8/26/2004, pp. 22] Personnel at United Airlines’ System Operations Control (SOC) center, near Chicago, learned that a plane had crashed into the World Trade Center when they saw the television coverage of the incident. Minutes later, they were informed that the WTC was hit by a hijacked American Airlines plane (see (Shortly After 8:48 a.m.) September 11, 2001). Shortly before 9:00 a.m., a supervisor at the airline’s maintenance office in San Francisco, California, called the SOC—the operations center—and said a United Airlines plane, Flight 175, had been reported as hijacked (see Shortly Before 9:00 a.m. September 11, 2001). [Wall Street Journal, 10/15/2001; 9/11 Commission, 8/26/2004, pp. 21-22] United Airlines’ usual procedure when there is a crisis involving one of its aircraft is to isolate that aircraft and move the handling of it to the crisis center, so as not to disrupt operations in the rest of the system.
Crisis Center Is Activated in about 30 Minutes - The crisis center, which is located just off the operations center, is apparently activated sometime around 9:00 a.m. It takes about 30 minutes for staffers to assemble and fully activate it. When the center is activated, a representative from every division of the airline’s corporate structure has to report to it, and once they arrive they have predetermined duties they are required to carry out. Clipboards are therefore distributed to operations center staffers, which show a list of people who are needed in the crisis center that they have to call. A phone bridge is set up with the airline’s other crisis centers, which are activated around this time in San Francisco and Denver, Colorado. [9/11 Commission, 11/20/2003 pdf file; 9/11 Commission, 11/21/2003 pdf file; 9/11 Commission, 8/26/2004, pp. 22] Patti Carson, United Airlines’ vice president of human resources, will later recall that after they see the live television coverage of Flight 175 crashing into the WTC at 9:03 a.m. on a screen in the operations center (see 9:03 a.m. September 11, 2001), “Without exchanging a word, every crisis team member in the room walked the 10 or 15 steps to the airline’s crisis center and took their positions.” [HR (.com), 7/1/2005]
Opening the Center Is 'the Single Most Significant Thing You Do' - The crisis center is “a terraced, theater-like room that resembled NASA’s Mission Control,” according to journalist and author Jere Longman. On one wall is a large screen on which United Airlines’ flights are displayed. [Longman, 2002, pp. 77; USA Today, 8/12/2002] Other screens in the center show CNN and other TV news channels. [9/11 Commission, 11/20/2003 pdf file] Opening the crisis center, according to Andy Studdert, United Airlines’ chief operating officer, “is the single most significant thing you do [at an airline], because once that happens… everybody in an airline has a second job and that second job is to either run the airline… or act to support the crisis.” Once the center has been opened, “3,000 people are put on an immediate activation,” Studdert will say. [Center for Values-Driven Leadership, 4/23/2012]
Different People Later Claim to Have Activated the Center - It is unclear when exactly the crisis center is activated and who activates it. Bill Roy, the SOC director, will say he is responsible for activating the center and he does this shortly after he learned a plane had crashed into the WTC. This is presumably sometime around 8:50 a.m. or shortly after. Roy will say that by around 9:00 a.m., he and his colleagues are in the process of activating the center. [9/11 Commission, 11/20/2003 pdf file; 9/11 Commission, 1/27/2004] But Rich Miles, the SOC manager, will indicate that he activates the center and he does this apparently at around 9:00 a.m. He will say that after they saw the television coverage of the burning WTC and then learned that the North Tower was hit by an American Airlines plane, staffers in the operations center discussed what to do and considered whether to open the crisis center. One member of staff went into the center, and started turning on computers and other equipment. Miles will recall that after the supervisor at the airline’s maintenance office in San Francisco called, shortly before 9:00 a.m., with the news that Flight 175 had been reported as hijacked, he begins activating the center. [9/11 Commission, 11/21/2003 pdf file; 9/11 Commission, 8/26/2004, pp. 21-22]
COO Is Authorized to Activate the Crisis Center - Other accounts will suggest that Studdert is responsible for activating the crisis center. Studdert will recall that sometime after 9:00 a.m., when he arrived at the operations center (see (8:50 a.m.-9:03 a.m.) September 11, 2001), he realizes that the airline is “in a crisis, and we immediately activate the crisis center.” [9/11 Commission, 1/27/2004; Center for Values-Driven Leadership, 4/23/2012] Furthermore, Ed Soliday, United Airlines’ vice president of safety and security, will indicate that Studdert is one of only a few people with authority to activate the crisis center. He will say that although the airline’s usual protocol is to obtain a “vote of three” before opening the center, both Studdert and he are empowered to order it activated on their own say-so. Since Soliday will arrive at United Airlines’ headquarters at around 9:35 a.m., this would suggest that only Studdert could order that the crisis center be activated on his own at the current time. [9/11 Commission, 11/21/2003 pdf file]
Center Remains Operational for Three Weeks - The crisis center will remain in operation around the clock every day for the next three weeks. It will provide United Airlines personnel around the country with instant access to resource providers and key decision makers. [9/11 Commission, 1/27/2004] The center was previously activated just 12 days ago, when Studdert ran a surprise “no-notice” exercise in which United Airlines personnel were led to believe that one of their planes had crashed (see August 30, 2001).

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

In the NORAD operations center in Cheyenne Mountain, Colorado, workers see the second aircraft crashing into the World Trade Center live on television. [Gazette (Colorado Springs), 10/7/2001] Major General Rick Findley, NORAD’s director of operations, later says that he now realizes “it was not an accident but a coordinated attack.” Then, he recalls, “At about that moment in time, every phone in this cab, and every phone over in the command center, and every phone in all the centers in this building were ringing off the hook.” Master Corporal Daniel Milne, the emergency action controller in the operations center, will similarly recall, “The feeling was total disbelief. Then the phones started ringing like crazy.” [Canadian Broadcasting Corporation, 9/11/2002; Legion Magazine, 11/2004] It is unclear what causes all the phones to simultaneously ring. According to Aviation Week and Space Technology magazine, after the second tower is hit, “Calls from fighter units… started pouring into NORAD and sector operations centers, asking, ‘What can we do to help?’” (see (After 9:03 a.m.) September 11, 2001) [Aviation Week and Space Technology, 6/3/2002] So this could be one factor. Also, a 1996 article in Airman magazine had quoted Stacey Knott, a technician in the NORAD operations center. She’d said, “Things can be pretty quiet in here.” However, “One of the busiest times is during exercises. This room fills up.… The phones are ringing off the hook, and I’ve got phones in each hand.” [Airman, 1/1996] On this morning, those in Cheyenne Mountain are in fact participating in a major exercise called Vigilant Guardian. [Aviation Week and Space Technology, 6/3/2002; CNN, 9/11/2006] This is reportedly only canceled “shortly after” the second attack (see (Shortly After 9:03 a.m.) September 11, 2001) [Airman, 3/2002; Filson, 2003, pp. 59] So it is plausible that this is also a factor in causing all the phones to suddenly ring. A similar thing appears to occur in the National Military Command Center (NMCC) at the Pentagon. According to a news article based on the recollections of two officers who are there, after the second plane hits the WTC, “Phones in the center began ringing off the hook.” [American Forces Press Service, 9/7/2006] Rick Findley later suggests that all the ringing phones are not a hindrance for NORAD, claiming, “The good news is we had lots of people here and we already had an operational architecture. We already had the command and control, the network, the phones, the data links. Everything was already in place that enabled us to react to the situation.” [Canadian Broadcasting Corporation, 9/11/2002]

A NORAD training exercise that is taking place this morning, presumably Vigilant Guardian (see (6:30 a.m.) September 11, 2001), is reportedly canceled shortly after 9:03, when the second World Trade Center tower is hit. [Airman, 3/2002] NORAD Commander Larry Arnold later says that after Flight 175 hits the South Tower, “I thought it might be prudent to pull out of the exercise, which we did.” [Filson, 2003, pp. 59] According to author Lynn Spencer: “The phone calls start flying between the various NORAD command centers. General Arnold calls Maj. Gen. Rick Findley” at NORAD’s operations center in Cheyenne Mountain, Colorado, “to give him the latest information and have him withdraw all forces from the simulated exercise.” [Spencer, 2008, pp. 86] Arnold will recall, “As we pulled out of the exercise we were getting calls about United Flight 93 and we were worried about that.” [Filson, 2003, pp. 59] Some early accounts say the military receives notification of the possible hijacking of Flight 93 at around 9:16 a.m. (see 9:16 a.m. September 11, 2001). [CNN, 9/17/2001; 9/11 Commission, 5/23/2003] However, the 9/11 Commission will later claim that NORAD’s Northeast Air Defense Sector (NEADS) first receives a call about Flight 93 at 10:07 a.m. (see 10:05 a.m.-10:08 a.m. September 11, 2001). [9/11 Commission, 6/17/2004] Arnold will add, “Then we had another call from Boston Center about a possible hijacking, but that turned out to be the airplane that had already hit the South Tower but we didn’t know that at the time.” [Filson, 2003, pp. 59]

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

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

[9/11 Commission, 8/26/2004, pp. 37] At 9:10, Melodie Homer, the wife of LeRoy Homer, contacts the operations center after seeing the second plane hitting the World Trade Center on television. Knowing her husband is flying, she requests that a message be sent to him, stating, “Your wife just wants to make sure you’re okay.” [Pittsburgh Channel, 9/19/2001; Longman, 2002, pp. 78; New York Observer, 2/15/2004; Discovery Channel, 2005] Melodie is told, “If you want to hang on, we’ll get a message back in a couple of minutes.” According to journalist and author Jere Longman, after no response is received, a second text message is sent. Although Melodie Homer’s message is later determined to have been received by the flight, there is still no reply. [Longman, 2002, pp. 81-82] However, the 9/11 Commission will only describe one message—not two—being sent to Homer, which it says happens at 9:22.

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

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

According to an early timeline laid out to CNN by unnamed but “informed defense officials,” the FAA informs NORAD at this time that Flight 93 may have been hijacked. [CNN, 9/17/2001] In public testimony before the 9/11 Commission in 2003, NORAD officials will similarly claim that the FAA first reports the possible hijacking of Flight 93 at this time. [9/11 Commission, 5/23/2003] Yet this is 12 minutes before the hijacking is meant to have occurred (see (9:28 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 38] One explanation is put forward that could possibly help explain the discrepancy: There are media reports that “investigators had determined from the cockpit voice recorder from United Airlines Flight 93… that one of the four hijackers had been invited into the cockpit area before the flight took off from Newark, New Jersey.” Cockpit voice recordings indicate that the pilots believed their guest was a colleague “and was thereby extended the typical airline courtesy of allowing any pilot from any airline to join a flight by sitting in the jumpseat, the folded over extra seat located inside the cockpit.” [Fox News, 9/24/2001; Herald Sun (Melbourne), 9/25/2001] This would be consistent with passenger phone calls from the plane, describing only three hijackers on Flight 93 (see (9:27 a.m.-10:03 a.m.) September 11, 2001). [Longman, 2002, pp. 120] However, the reports will not be confirmed. The 9/11 Commission Report will dismiss the claim that NORAD was alerted at 9:16, stating, “In public testimony before this Commission in May 2003, NORAD officials stated that at 9:16, NEADS received hijack notification of United 93 from the FAA. This statement was incorrect. There was no hijack to report at 9:16. United 93 was proceeding normally at that time.” [9/11 Commission, 7/24/2004, pp. 34] No further explanations will be offered for the incorrect timelines. NORAD’s own initial timeline, released on September 18, 2001, will not give a time for when the FAA alerted it to Flight 93. It will only say that the FAA and its Northeast Air Defense Sector (NEADS) “established a line of open communication discussing AA Flt 77 and UA Flt 93.” [North American Aerospace Defense Command, 9/18/2001]

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

[9/11 Commission, 1/27/2004; 9/11 Commission, 7/24/2004, pp. 455] The airline’s air traffic control coordinator sends a message to all of the airline’s dispatchers, telling them: “There may be addnl [additional] hijackings in progress. You may want to advise your flts [flights] to stay on alert and shut down all cockpit access inflt [in flight]. Sandy per Mgmt.” United Airlines dispatchers began notifying their aircraft that planes had crashed into the World Trade Center at 9:03 (see 9:03 a.m. and After September 11, 2001). However, with the exception of one dispatcher (see 9:19 a.m. September 11, 2001), the airline has so far not sent any warnings to its aircraft. [9/11 Commission, 8/26/2004, pp. 36-37] United Airlines did not initially realize the second plane to hit the WTC was one of its own (see Between 9:10 a.m. and 9:20 a.m. September 11, 2001), and it is not until 9:22 that it notifies its dispatchers that UAL Flight 175 has been involved in “an accident” in New York (see 9:22 a.m. September 11, 2001).

Ed Ballinger, the United Airlines flight dispatcher monitoring Flight 93, sends a warning message to this flight, telling the pilots to beware of any cockpit intrusion. [9/11 Commission, 7/24/2004, pp. 11] At 9:21, United Airlines instructed its dispatchers to warn their flights to secure their cockpit doors (see 9:21 a.m. September 11, 2001), but Ballinger had already taken the initiative two minutes earlier to begin warning the 16 flights he is monitoring (see 9:19 a.m. September 11, 2001). His text message reads: “Beware any cockpit intrusion… Two aircraft in NY hit [World] Trade Center builds.” Because this message is sent out to Ballinger’s 16 aircraft in groups, it is not until 9:23 a.m. that it is transmitted to Flight 93. [9/11 Commission, 1/27/2004; 9/11 Commission, 8/26/2004, pp. 26 and 37] The warning is received in the plane’s cockpit one minute later. [9/11 Commission, 7/24/2004, pp. 11] Then, at 9:26, Flight 93 pilot Jason Dahl responds with the text message, “Ed confirm latest mssg plz [message please]—Jason.” Apart from a routine radio contact with the FAA’s Cleveland Center a minute later (see 9:27 a.m. September 11, 2001), this is the last normal communication made from Flight 93’s cockpit before the hijacking occurs. [9/11 Commission, 8/26/2004, pp. 38] Ballinger will later complain: “One of the things that upset me was that they knew 45 minutes before that American Airlines [Flight 11] had a problem. I put the story together myself [from news accounts]. Perhaps if I had the information sooner, I might have gotten the message to [Flight] 93 to bar the door.” [Chicago Daily Herald, 4/14/2004]

[Source: FAA]Having entered the center’s airspace, Flight 93 establishes radio contact with the FAA’s Cleveland Center, a regional air traffic control center that guides long-range, high altitude flights. The pilot reports simply that his flight is experiencing intermittent light choppy air, and does not indicate there being any problems on board, saying, “Good morning Cleveland, United 93 with you at three-five-oh [35,000 feet], intermittent light chop.” The controller, John Werth, is busy with other flights, so does not initially respond. A minute later, Flight 93 radios again, “United 93 checking in three-five-oh.” Werth replies, “United 93, three-five-zero, roger.” [Gregor, 12/21/2001 pdf file; Longman, 2002, pp. 69; 9/11 Commission, 8/26/2004, pp. 37; CBS News, 9/10/2006] Two minutes later, Flight 93 will make its final radio communication before the hijacker takeover occurs (see 9:27 a.m. September 11, 2001).

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

[Source: Publicity photo]According to the 9/11 Commission, less than a minute after Flight 93 acknowledged a routine radio transmission from the FAA’s Cleveland Center (see 9:27 a.m. September 11, 2001), John Werth—the controller handling the flight—and pilots of other aircraft in the vicinity of Flight 93 hear “a radio transmission of unintelligible sounds of possible screaming or a struggle from an unknown origin.” [Federal Aviation Administration, 9/11/2001; 9/11 Commission, 6/17/2004; CBS News, 9/10/2006] Someone, presumably Flight 93’s pilot Jason Dahl, is overheard by controllers as he shouts, “Mayday!” [New York Times, 7/22/2004] Seconds later, the controller responds, “Somebody call Cleveland?” Then there are more sounds of screaming and someone yelling, “Get out of here, get out of here.” [Toronto Sun, 9/16/2001; Newsweek, 9/22/2001; Observer, 12/2/2001; MSNBC, 7/30/2002; 9/11 Commission, 6/17/2004] Then the voices of the hijackers can be heard talking in Arabic. The words are later translated to show they are talking to each other, saying, “Everything is fine.” [Newsweek, 12/3/2001] Later, passenger phone calls will describe two dead or injured bodies just outside the cockpit; presumably these are the two pilots.

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.

Shortly before Flight 93 reverses direction and heads east, someone in its cockpit radios in and asks the FAA for a new flight plan, with a final destination of Washington, DC. [ABC News, 9/11/2001; ABC News, 9/14/2001] Jeff Krawczyk, the chief operating officer of a company that tracks aircraft movements, later comments, “We hardly ever get a flight plan change. Very unusual.” [Washington Business Journal, 9/11/2001] Who it is that makes this request is unclear. The hijacker takeover of Flight 93 occurred around 9:28 a.m. (see (9:28 a.m.) September 11, 2001) [9/11 Commission, 7/24/2004, pp. 11] , so it is presumably made by one of the hijackers. Twenty-five minutes later the pilot hijacker will also program a new destination into the plane’s navigational system (see 9:55 a.m. September 11, 2001).

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).

FAA’€™s Cleveland Center.FAA’€™s Cleveland Center. [Source: ABC News]According to the 9/11 Commission, at about this time Cleveland flight control specifically asks the FAA Command Center whether someone has requested the military to launch fighters toward Flight 93. Cleveland offers to contact a nearby military base. The Command Center replies that FAA personnel well above them in the chain of command have to make that decision and are working on the issue. [9/11 Commission, 6/17/2004] Cleveland overheard a hijacker say there was a “bomb on board” at 9:32 a.m. and passed the message to FAA higher ups (see (9:32 a.m.) September 11, 2001). According to John Werth, the Cleveland controller handling Flight 93, “Within three or four minutes, probably, of when [the hijacking] happened, I asked if the military was advised yet. Had anybody called the military? They said, ‘don’t worry. That’s been taken care of,’ which I think to them, meant they had called the command center in Washington.” [CBS News, 9/10/2006]

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

Firefighter Timothy Brown, a supervisor at New York City’s Office of Emergency Management, is told that a suspicious plane that was reportedly flying toward New York has crashed. [Firehouse, 1/31/2003] After the second hijacked plane crashed into the World Trade Center, at 9:03 a.m. (see 9:03 a.m. September 11, 2001), Brown went to the lobby of the South Tower to help open a command post. [Project Rebirth, 6/30/2002 pdf file; TEDx Talks, 10/7/2015] While there, he heard over his radio that another suspicious aircraft, in addition to the planes that hit the Twin Towers, was heading toward New York (see (9:30 a.m.) September 11, 2001). Since then, he has talked to the New York State Emergency Management Office about getting fighter jets to protect New York (see (Shortly After 9:37 a.m.) September 11, 2001). [Firehouse, 1/31/2003] He then told people at the command post they should “be prepared to be hit again.” [Project Rebirth, 6/30/2002 pdf file] However, he now hears over his radio that “the third plane was no longer inbound, that it had crashed.” This news “gave us a sigh of relief,” he will later comment. [Firehouse, 1/31/2003] The identity of this third suspicious plane is unclear. Brown will say it turned out to be “the one that crashed in Pennsylvania,” meaning Flight 93. [Project Rebirth, 6/30/2002 pdf file] However, this is apparently impossible, since Brown will describe hearing it has crashed before 9:59 a.m., when the South Tower collapses (see 9:59 a.m. September 11, 2001), but Flight 93 will reportedly crash later on, at 10:03 a.m. (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001).

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

The FAA’s Cleveland Center receives a call from NORAD’s Northeast Air Defense Sector (NEADS), incorrectly notifying it that Delta Air Lines Flight 1989 is a confirmed hijacking. A supervisor then rushes around the center, informing all the controllers and managers of this. [9/11 Commission, 10/2/2003 pdf file; 9/11 Commission, 10/2/2003 pdf file; 9/11 Commission, 2004]
Cleveland Realized Delta 1989 Not Hijacked - At around 9:30 a.m., Cleveland Center air traffic controllers heard the sounds from Flight 93 as it was being hijacked, but initially thought these came from Delta 1989 (see (9:28 a.m.-9:33 a.m.) September 11, 2001). [USA Today, 8/13/2002] Due to the Delta pilots’ normal responses to subsequent radio transmissions, John Werth—the controller monitoring both flights—concluded that the hijacked aircraft was in fact Flight 93. [9/11 Commission, 10/1/2003 pdf file; USA Today, 9/11/2008] However, at around 9:39, the FAA’s Boston Center guessed that Delta 1989 might be hijacked and called NEADS to report the plane as a possible hijacking (see 9:39 a.m. September 11, 2001). [9/11 Commission, 2004; 9/11 Commission, 7/24/2004, pp. 28] NEADS then begins alerting FAA centers of this. [Vanity Fair, 8/1/2006]
NEADS Calls Cleveland Center - Greg Dukeman, the military operations specialist in the traffic management unit at Cleveland Center, receives a call from a female member of staff at NEADS, one of its ID technicians. He passes the call on to supervisor Kim Wernica. The caller says Delta 1989 is “a confirmed hijack.” Wernica then goes “running back and forth” around the center, informing controllers and managers of what she has been told. [North American Aerospace Defense Command, 9/11/2001; 9/11 Commission, 10/2/2003 pdf file; 9/11 Commission, 10/2/2003 pdf file; 9/11 Commission, 2004]
Controller Disputes NEADS's Information - Wernica rushes up to John Werth and tells him, “It’s the Delta, it’s the Delta!” She says a military liaison on the phone has confirmed that the Delta jet has been hijacked. Werth responds that he is pretty sure that Flight 93, not Delta 1989, has been hijacked. When Wernica returns a few moments later, Werth tells her that Delta 1989 is “fine—at least for now.” Wernica consults again on the phone and then comes back, saying, “They said it’s a confirmed hijack and a bomb threat.” Werth thinks to himself that the bomb threats had come from Flight 93 (see (9:32 a.m.) September 11, 2001 and (9:39 a.m.) September 11, 2001), and is therefore convinced the caller must be confusing the two flights. He tells Wernica, “Tell them they’re full of it!” [9/11 Commission, 10/1/2003 pdf file; USA Today, 9/11/2008]

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).

In the battle cab at NORAD’s Northeast Air Defense Sector (NEADS), Colonel Robert Marr instructs his troops to contact every Air National Guard unit in the Northeast US and tell them to get their fighter jets airborne. [Spencer, 2008, pp. 180] NEADS has already launched the four fighters in the Northeast US that are kept on alert, ready to take off at a moment’s notice: Two F-15s were scrambled from Otis Air National Guard Base at 8:46 (see 8:46 a.m. September 11, 2001) and two F-16s were scrambled from Langley Air Force Base at 9:24 (see 9:24 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 17, 20, 27]
NEADS Calls Air National Guard Units - Marr now realizes these four jets are not enough, and tells his troops: “The nation is under attack. Get ‘em in the air!” Officers in the NEADS battle cab and on its operations floor begin calling Air National Guard units, one after another. The NEADS officers are surprised to find that wing commanders have been anticipating their call for help, and have already started arming fighter jets. According to author Lynn Spencer: “Although wing commanders do not necessarily have the authority to arm their planes with live missiles, nor Marr the authority to call them into action, these are not ordinary times. Marr can’t help but think that the incredible response is due to the fact that the Guard units are Title 32, or state-owned. They report to the governors of their respective states, and the wing commanders have every confidence that their governors will support them.” [9/11 Commission, 10/30/2003 pdf file; Spencer, 2008, pp. 180]
Time of Order Unclear - Exactly when Marr instructs his officers to contact the Air National Guard units is unclear. It appears to be at around 9:50 a.m., or some time shortly after. At the Continental US NORAD Region (CONR) headquarters in Florida, CONR commander Major General Larry Arnold began contacting all three CONR sectors (which includes NEADS) at around 9:45 a.m., after learning the Pentagon had been hit and realizing the attacks were no longer isolated to New York. His instruction to the sectors was, “Generate, generate, generate!” meaning, “Get as many fighters as you can into the sky now!” [Spencer, 2008, pp. 177-178] General Ralph Eberhart, the commander of NORAD, directed “all air sovereignty aircraft to battle stations, fully armed,” at 9:49 a.m. (see 9:49 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 38] But “battle stations” means only that pilots get into their aircraft with the engines turned off, so they are ready to launch if a scramble order follows. [Filson, 2003, pp. 55; Spencer, 2008, pp. 27] The Toledo Blade will report, “By 10:01 a.m., [NEADS] began calling several bases across the country for help.” [Toledo Blade, 12/9/2001] According to the Newhouse News Service, though, Marr apparently gave his order significantly earlier. It will report that, when the South Tower was hit at 9:03, NEADS personnel “looked to Col. Robert Marr, who rallied the operation: Get to the phones. Call every Air National Guard unit in the land. Prepare to put jets in the air. The nation is under attack” (see (After 9:03 a.m.) September 11, 2001). [Newhouse News Service, 1/25/2002] Air National Guard jets will reportedly take off from Toledo Express Airport in Ohio at 10:17 a.m., in response to NEADS’s call for help, and, according to Spencer, NEADS instructs Otis Air Base to launch all its available aircraft at around 10:20 a.m. (see (10:20 a.m.) September 11, 2001).

A radio transmitter carried by aircraft that is designed to go off automatically if a plane crashes is activated in the vicinity of the city of Ann Arbor in southeast Michigan, although the distress signal is presumably a false alarm. Details of the distress signal will be described when an unidentified individual calls the FAA’s Cleveland Center at around 10:19 a.m. and tells an air traffic controller there, “I’ve got an ELT reported over Ann Arbor.” [Federal Aviation Administration, 9/11/2001; Federal Aviation Administration, 10/14/2003] An “ELT” is an emergency locator transmitter, a device carried on most general aviation aircraft in the US that is designed to automatically begin transmitting a distress signal if a plane should crash, so as to help search and rescue efforts in locating the downed aircraft. [Federal Aviation Administration, 3/23/1990; Federal Aviation Administration, 7/12/2001; Aircraft Owners and Pilots Association, 1/22/2009] The caller will not say who reported the ELT signal to him. But he will say the signal “started at 13:53” Zulu time, which is 9:53 a.m. Eastern time. Presumably realizing the signal was therefore activated over 25 minutes earlier, the caller will add, “Wait a minute, that don’t make any sense.” But the Cleveland Center controller will tell him: “Yeah, it does. It might have been late to be…” The caller will then say, “Okay, well I’ve got an ELT reported over Ann Arbor,” before the call ends. [Federal Aviation Administration, 9/11/2001] Further details of the ELT signal and what might have caused it are unknown. Flight 93 will crash in rural Pennsylvania about 10 minutes after the signal over Ann Arbor is activated (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 30] However, apparently no ELT signal will go off when it crashes (see 10:07 a.m. September 11, 2001).

He dials in the navigational code for Washington’s Reagan National Airport, which is just four miles from the White House, and an arrival time of 10:28 a.m. The 9/11 Commission will say this further indicates that the plane’s intended target is the nation’s capital.

Controller Enters New Flight Plan for Flight 93 - Justice changes the flight’s destination code from “SFO,” the code for San Francisco International Airport, to “DCA,” the code for Ronald Reagan Washington National Airport. [St. Petersburg Times, 9/12/2001] An FAA chronology will specify that she changes the flight plan “direct HGR [the code for Hagerstown Regional Airport in Maryland] to DCA.” [Federal Aviation Administration, 9/11/2001] Another FAA chronology will similarly state that Justice reroutes Flight 93 “direct to Hagerstown direct to Washington National.” [Federal Aviation Administration, 12/6/2001] Flight 93’s tag therefore now reads, “Hagerstown—National,” according to Justice. [9/11 Commission, 10/2/2003 pdf file]
New Flight Plan Not Due to Communication with Pilot - The reason Justice enters a new flight plan for Flight 93 is unclear. A minute earlier, the hijacker pilot on Flight 93 reprogrammed the plane’s navigational system for the new destination of Reagan Airport (see 9:55 a.m. September 11, 2001). [Longman, 2002, pp. 182; 9/11 Commission, 7/24/2004, pp. 457] And according to the St. Petersburg Times, controllers typically only change a plane’s destination when this is requested by the pilots. [St. Petersburg Times, 9/12/2001] But one of the FAA chronologies will state that Justice’s change to the flight plan is “not a result of any communication with the pilot.” [Federal Aviation Administration, 9/11/2001]
Flight Plan Changed to Aid Handoff to Washington Controllers - Justice will later explain why she changes the flight plan. She will state that Flight 93 appears to be heading toward the airspace of the FAA’s Washington Center, and so, in “an attempt to expedite the situation,” she enters the change of routing to reflect Hagerstown Airport to Reagan Airport. She will say she does this “only to forward [the] information [about Flight 93] to the sectors the aircraft appeared to be tracking toward.” [Federal Aviation Administration, 9/12/2001 pdf file] Justice will tell the 9/11 Commission that she changes the routing when she sees Flight 93 is heading eastbound. She will say, “The easiest way to do a handoff is to change the flight plan,” and also say she changes the flight plan “to show that Washington Center was the recipient.” According to Justice, the “controversial step” she takes is “putting in Hagerstown, because the misconception was that she had communicated with the plane and cleared it through.” [9/11 Commission, 10/2/2003 pdf file] John Werth, another controller at the Cleveland Center, will tell the 9/11 Commission that Justice enters the new destination for Flight 93 “because she knew it would be easier to track the primary [radar track for the aircraft] when the computer has a flight plan to work with.” [9/11 Commission, 10/1/2003 pdf file] After changing the flight plan, Justice calls the Potomac Sector radar position at the Washington Center and tells the controller there to “pull up the data block” for Flight 93. Justice will say it is clear to the Washington Center controller that she has created the new destination in order to make it easier to locate the plane. [Federal Aviation Administration, 9/12/2001 pdf file; 9/11 Commission, 10/2/2003 pdf file]
New Flight Plan Causes False Reports of Plane Approaching Washington - According to author Lynn Spencer, the new flight plan creates a “coast track” of Flight 93 on the traffic situation displays at air traffic control facilities. “A coast track,” Spencer will write, “differs from a radar track in that it is not supported by radar returns but rather by a computer-generated, projected course for the flight. Although this track did not appear on controller radar screens, its presence on their [traffic situation displays] allowed Washington controllers to monitor the flight’s progression toward Washington.” According to Spencer, the presence of this coast track leads to incorrect reports of an aircraft approaching Washington in the minutes after Flight 93 crashes. She will write, “A controller in Washington, unaware that the flight had crashed, was calling position reports for the coast track of United 93 to the White House (see (Between 10:10 a.m. and 10:18 a.m.) September 11, 2001)… as well as the FBI at the Pentagon (where firefighters were evacuated and the firefight suspended in anticipation of a second impact)” (see (10:15 a.m.-10:38 a.m.) September 11, 2001).

Since around 9:54, Flight 93 passenger Elizabeth Wainio has been speaking by phone with her stepmother Esther Heymann (see (9:54 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 44] Wainio ends her call saying, “They’re getting ready to break into the cockpit. I have to go. I love you. Good-bye.” She then hangs up. [Longman, 2002, pp. 172] The 9/11 Commission concludes that the passengers’ revolt against the hijackers that Wainio is referring to begins at 9:57 a.m. [9/11 Commission, 8/26/2004, pp. 45] Yet according to journalist and author Jere Longman, Wainio’s call lasts 11 minutes, and ends at “just past ten” o’clock, which is several minutes after the revolt starts. [Longman, 2002, pp. 171-172] In fact, if Wainio’s call began around 9:54, as is officially claimed, and lasts 11 minutes, it would end around 10:05. This is after official accounts claim Flight 93 crashed, but before the crash time of 10:06 later provided by an analysis of seismic records (see (10:03 a.m.-10:10 a.m.) September 11, 2001). However, according to the 9/11 Commission and a summary of passenger phone calls presented at the 2006 Zacarias Moussaoui trial, Wainio’s call only lasts four-and-a-half minutes. This would mean it ends just shortly after the passenger revolt begins.

An F-16 flies over New York City on September 12, 2001. Smoke is still rising from the World Trade Center. [Source: Air National Guard]An air traffic controller at the FAA’s New York Center radios the pilots launched from Otis Air National Guard Base in response to Flight 11 (see 8:46 a.m. September 11, 2001) and tells them they may have to take out a hijacked aircraft. One of the two Otis pilots, Major Daniel Nash, will later recall, “The New York controller did come over the radio and say if we have another hijacked aircraft we’re going to have to shoot it down.” [BBC, 9/1/2002] However, he will add that this is just “an off-the-cuff statement.” [Cape Cod Times, 8/21/2002] It is unclear at what time this communication occurs, though a BBC documentary will place it at about the time the South Tower collapses, which would be around 9:59 a.m. [BBC, 9/1/2002] NORAD’s Northeast Air Defense Sector (NEADS) has already radioed one of the Otis pilots to check that he is prepared to shoot down a hijacked aircraft (see (9:35 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 10:18 a.m.) September 11, 2001 and 10:10 a.m.-10:11 a.m. September 11, 2001), and this may be another such report.

Flight 93’s transponder, which was switched off after Flight 93 was hijacked, is turned back on just before the plane crashes, thereby revealing the plane’s altitude to air traffic controllers at the FAA’s Cleveland Center. [Federal Bureau of Investigation, 9/11/2001; MSNBC, 9/11/2002] A transponder is a device that sends a plane’s identifying information, speed, and altitude to controllers’ radar screens. [Washington Post, 9/16/2001] Flight 93’s transponder was switched off at around 9:40 a.m. (see (9:40 a.m.) September 11, 2001), although Cleveland Center controllers have still been able to follow Flight 93 on “primary radar,” which shows less information about a flight (see (9:41 a.m.-10:06 a.m.) September 11, 2001). [Federal Bureau of Investigation, 1/8/2002; 9/11 Commission, 7/24/2004, pp. 29; Cleveland Plain Dealer, 7/3/2011]
Plane Shown to Be Flying at 8,200 Feet - Flight 93’s transponder is reactivated at 10:02 a.m. and 50 seconds, and then stays on for “approximately 20 seconds,” according to “information from the flight data” provided to the FBI later today by Rick Kettell, the manager of the Cleveland Center. After the transponder is turned back on, Flight 93’s radar track is observed by Cleveland Center controllers Linda Justice and Stacey Taylor. The information from the transponder shows them that Flight 93 is at an altitude of 8,200 feet. [Federal Bureau of Investigation, 9/11/2001; Federal Aviation Administration, 9/16/2001 pdf file; 9/11 Commission, 10/2/2003 pdf file]
Plane Soon Disappears from Radar Screens - Flight 93 will crash into the ground at 10:03 a.m. and 11 seconds, according to the 9/11 Commission Report, less than 30 seconds after the transponder is reactivated (see (10:03 a.m.-10:10 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 30] Cleveland Center controllers will see the plane completely disappear from their radar screens around that time. [MSNBC, 9/11/2002] A Cleveland Center controller will then report, apparently over an FAA teleconference, that Flight 93’s transponder “came on briefly and then it went back off with the primary, and now we’ve lost him completely.” [Federal Aviation Administration, 9/11/2001] “I had two radar hits on [Flight 93],” Taylor will recall, adding that she then “lost the primary target on [Flight 93] and we suspected it had gone down.” [Federal Aviation Administration, 9/16/2001 pdf file] The reason Flight 93’s transponder is switched back on just before the plane crashes is unclear. Taylor will comment, a year after 9/11: “That’s something we’ve always wanted to know. Why did the transponder come back on?” She will say Cleveland Center controllers wondered this because they believed that “the hijackers had shut it off so that they couldn’t be tracked.” [MSNBC, 9/11/2002]

Smoke rising, minutes after Flight 93 crashes in Pennsylvania.Smoke rising, minutes after Flight 93 crashes in Pennsylvania. [Source: CNN]Exactly when Flight 93 crashes is unclear. According to NORAD, Flight 93 crashes at 10:03 a.m. [North American Aerospace Defense Command, 9/18/2001] The 9/11 Commission gives an exact time of 11 seconds after 10:03 a.m. It will claim this “time is supported by evidence from the staff’s radar analysis, the flight data recorder, NTSB [National Transportation Safety Board] analysis, and infrared satellite data.” It does note that “[t]he precise crash time has been the subject of some dispute.” [9/11 Commission, 6/17/2004] However, a seismic study authorized by the US Army and drafted by scientists Won-Young Kim and Gerald Baum to determine when the plane crashed will conclude that the crash happened at 10:06:05 a.m. [Kim and Baum, 2002 pdf file; San Francisco Chronicle, 12/9/2002] The discrepancy is so puzzling that the Philadelphia Daily News will publish an article on the issue, titled “Three-Minute Discrepancy in Tape.” This notes that leading seismologists agree on the 10:06 a.m. time, give or take a couple of seconds. [Philadelphia Daily News, 9/16/2002] The New York Observer will note that, in addition to the seismology study, “The FAA gives a crash time of 10:07 a.m. In addition, the New York Times, drawing on flight controllers in more than one FAA facility, put the time at 10:10 a.m. Up to a seven-minute discrepancy? In terms of an air disaster, seven minutes is close to an eternity. The way our nation has historically treated any airline tragedy is to pair up recordings from the cockpit and air traffic control and parse the timeline down to the hundredths of a second. However, as [former Inspector General of the Transportation Department] Mary Schiavo points out, ‘We don’t have an NTSB (National Transportation Safety Board) investigation here, and they ordinarily dissect the timeline to the thousandth of a second.’” [New York Observer, 2/15/2004]

In response to the terrorist attacks in the United States, the Russian military cancels a major training exercise it has been holding, turning back its bomber aircraft and calling off planned missile testing. [Toronto Star, 12/9/2001; Defense Video and Imagery Distribution System, 9/8/2011] The Russian Air Force began the exercise—which was being conducted over the North Atlantic, Pacific, and Arctic Oceans—on September 10 (see September 10, 2001), and had planned for it to continue until September 14. NORAD has deployed fighter jets to Alaska and Northern Canada to monitor the exercise (see September 9, 2001).
Russians Cancel Exercise to Avoid Confusion - The Russians now call off their exercise, “to avoid misunderstandings, since US defenses were now on high alert in case of further possible terrorist attacks,” according to BBC correspondent Bridget Kendall. [BBC, 2001, pp. 161; North American Aerospace Defense Command, 9/9/2001; Washington Times, 9/11/2001] “The Russians knew NORAD would have its hands full,” the Toronto Star will report. Lieutenant Colonel William Glover, the commander of NORAD’s Air Warning Center, will say the Russians stop their exercise “because they understood the magnitude of what had happened to us in the United States. They didn’t want any questions; they didn’t want us worrying about what they would be doing or entering our Air Defense Identification Zone.”
Russia Tells US about Canceling Exercise - The Russians notify the US of their actions. Captain Michael Jellinek, the director of plans, requirements, and readiness at NORAD’s Cheyenne Mountain Operations Center in Colorado, will later recall: “They sent the message to the State Department clearly and unambiguously: ‘Don’t worry about our movements, we’re going to stay down for a while.’”
Russia's Actions Are 'Very Helpful' to US - It is unclear when exactly the Russians call off their exercise. According to the Toronto Star, they “immediately” cancel it “on seeing the attacks in New York and Washington.” Glover will say the Russians notify the US that they are stopping their exercise “after the United Flight 93 went into Shanksville” (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001). Jellinek will call the Russians’ actions in canceling their exercise “[v]ery, very useful. Very helpful.” Glover will comment, “[T]hat was amazing to me, personally, the fact that they stopped their exercise and… that they told us that they were going to stop the exercise.” [Toronto Star, 12/9/2001; Defense Video and Imagery Distribution System, 9/8/2011] Russian President Vladimir Putin will contact the White House and inform National Security Adviser Condoleezza Rice that the Russians are voluntarily canceling their exercise (see Between 10:32 a.m. and 11:45 a.m. September 11, 2001).

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]

The military liaison at the FAA’s Cleveland Center is informed that Flight 93 has been hijacked and is given information about its location. It is unclear when the liaison first receives this information, but it must happen before 10:07, as he telephones NORAD’s Northeast Air Defense Sector (NEADS) at this time to pass on the information (see 10:05 a.m.-10:08 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 30] Military liaison officers at the FAA’s Command Center are also said to be informed of the hijacking of Flight 93 (see After 9:34 a.m. September 11, 2001).

The FAA’s Cleveland Center, which had the last contact with Flight 93 before it crashed, suggests that no distress signal indicating a plane crash has occurred was picked up at the time Flight 93 went down. [Federal Aviation Administration, 9/11/2001; Federal Aviation Administration, 9/11/2001] Flight 93 reportedly crashed in rural Pennsylvania at 10:03 a.m. (see (10:03 a.m.-10:10 a.m.) September 11, 2001). [National Transportation Safety Board, 2/19/2002 pdf file; 9/11 Commission, 7/24/2004, pp. 30; USA Today, 9/11/2008] An air traffic controller at the Cleveland Center now says, apparently over an FAA teleconference, that someone has reported seeing black smoke in the vicinity of Flight 93’s last known position, near Johnstown, Pennsylvania. The controller then says, “We’re trying to see if we can get an ELT check.” [Federal Aviation Administration, 9/11/2001; Federal Aviation Administration, 9/11/2001] An “ELT” is an emergency locator transmitter, a device carried on most general aviation aircraft in the US that is designed to automatically start transmitting a distress signal if a plane should crash, so as to help search and rescue efforts in locating the downed aircraft. [Federal Aviation Administration, 3/23/1990; Federal Aviation Administration, 7/12/2001; Aircraft Owners and Pilots Association, 1/22/2009] The Cleveland Center controller’s information, as an FAA timeline will later state, therefore indicates that “[n]o ELT” signal has been picked up in the area where Flight 93 apparently crashed “at this time.” [Federal Aviation Administration, 9/11/2001] Someone at the FAA’s Command Center in Herndon, Virginia, acknowledges the controller’s communication, responding, “Copy that, Command Center.” [Federal Aviation Administration, 9/11/2001] Whether anyone will subsequently report picking up an ELT signal in the area where Flight 93 apparently crashed is unclear. Major Allan Knox, who works at the Air Force Rescue Coordination Center, which is “the contact for credible” ELT signals, will tell the 9/11 Commission that he “does not recall an ELT detection being brought to his attention” today. [9/11 Commission, 10/1/2003 pdf file; 9/11 Commission, 10/6/2003 pdf file] However, an ELT signal was picked up in the New York area by the pilot of an aircraft minutes before Flight 11 crashed into the North Tower of the World Trade Center (see 8:44 a.m. September 11, 2001) and another ELT signal was picked up in the New York area by the same pilot minutes before Flight 175 crashed into the South Tower (see 8:58 a.m. September 11, 2001).

Unaware the aircraft has crashed, United Airlines flight dispatcher Ed Ballinger instructs Flight 93 not to divert to Washington. At 10:10, he sends a text message to Flight 93, stating: “Don’t divert to DC. Not an option.” A minute later, he resends this same message to it. [9/11 Commission, 1/27/2004; 9/11 Commission, 8/26/2004, pp. 46] Someone on Flight 93 had contacted the FAA at 9:30, requesting a new flight plan with the destination of Washington (see 9:30 a.m. September 11, 2001), and at 9:55 the pilot hijacker reprogrammed the plane’s navigational system for the new destination of Washington’s Reagan National Airport (see 9:55 a.m. September 11, 2001). United Airlines will not confirm that Flight 93 has crashed until around 10:15 (see (10:07 a.m.-10:15 a.m.) September 11, 2001), and will notify its employees of this at 10:17 (see 10:17 a.m. September 11, 2001).

An officer at NORAD’s operations center in Cheyenne Mountain, Colorado, calls NORAD’s Northeast Air Defense Sector (NEADS) and asks it to stop “exercise inputs” being sent to the operations center.
NORAD Calls Chief of Exercises at NEADS - The NORAD officer, a “Captain Taylor,” calls NEADS, where the phone is answered by Captain Brian Nagel. [North American Aerospace Defense Command, 9/11/2001] Nagel is chief of NEADS live exercises. [Filson, 2003, pp. 74] After introducing himself, Taylor says, “What we need you to do right now is to terminate all exercise inputs coming into Cheyenne Mountain.” Nagel gives Taylor an extension number and suggests that he call it to get the exercise inputs stopped. Taylor replies, “I’ll do that.” [North American Aerospace Defense Command, 9/11/2001] According to an article in Vanity Fair, “inputs” are simulated scenarios that are put into play for training exercises. [Vanity Fair, 8/1/2006] NORAD has been conducting a major exercise this morning called Vigilant Guardian (see (6:30 a.m.) September 11, 2001). [Arkin, 2005, pp. 545]
Exercise Includes Simulated Radar Information - Taylor is presumably referring specifically to false tracks that have been transmitted onto NORAD radar screens for the exercise. NORAD has the capability to inject simulated material, including mass attacks, into the system during exercises, “as though it was being sensed for the first time by a radar site.” [US Department of Defense, 1/15/1999] All of the operations personnel at NEADS have been instructed to “have their sim switches turned ‘on’” (presumably to allow simulated information to appear on their radar screens) from September 6 until the end of Vigilant Guardian, on September 13. An information page on the exercise stated that a “sim test track will be in place and forward told [i.e. transferred to a higher level of command] to both NORAD and CONR,” NORAD’s Continental United States Region. [Northeast Air Defense Sector, 8/23/2001]
Exercise Supposedly Called Off Earlier - More than 50 members of the battle staff at the NORAD operations center have been participating in Vigilant Guardian this morning. [Airman, 3/2002; 9/11 Commission, 3/1/2004 pdf file] Some accounts will claim this exercise was canceled shortly after 9:03 a.m., when the second World Trade Center tower was hit (see (Shortly After 9:03 a.m.) September 11, 2001). [Airman, 3/2002; Filson, 2003, pp. 59] And a report in the Toronto Star will state, “Any simulated information” for the exercise was “purged from the [radar] screens” at the operations center shortly before the second tower was hit (see (9:00 a.m.) September 11, 2001). [Toronto Star, 12/9/2001] But a member of staff at NEADS complained at 9:30 a.m. about simulated material still appearing on radar screens there, and at 9:34 a.m. the NEADS surveillance technicians were instructed to turn off their “sim switches” (see 9:34 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]

Jon Treacy.Jon Treacy. [Source: US Air Force]Otis Air National Guard Base in Cape Cod, Massachusetts, receives the order from NORAD’s Northeast Air Defense Sector (NEADS) to launch all its available fighter jets.
Commander Briefs Pilots - A number of Otis pilots that were recalled from a training mission about an hour earlier (see (9:25 a.m.-9:45 a.m.) September 11, 2001) and other pilots that have recently come to the base from their homes are gathered in front of the operations desk. Squadron commander Lieutenant Colonel Jon Treacy tells them: “This is what we know. This is clearly a national emergency. Two aircraft have been hijacked and flown into the World Trade Center. The Pentagon has been attacked. We need to get all our jets ready to go because we’re not sure where this is heading. We have information that there are more coming.” He instructs the pilots: “You must be prepared to meet any surprise.… You may be taking out an airliner. You must engage. You cannot fail. Our nation is relying on us.” He gives them their assignments, saying whether they are required to fly now or whether they will be needed later on, to take over when other pilots have landed.
Launch Order Received - Just after Treacy finishes giving his briefing, someone comes into the room yelling out that NEADS has called the base with important orders. The person says, “We have to get everything we have airborne now!” [Spencer, 2008, pp. 244-245] NEADS started contacting Air National Guard bases around the Northeast US by about 10:00 a.m., with the instruction to get their fighters airborne (see (Between 9:50 a.m. and 10:00 a.m.) September 11, 2001). [Toledo Blade, 12/9/2001; Spencer, 2008, pp. 180]
Pilots Head Out, but Most Jets Not Yet Armed - Treacy yells at his men, “Go, go, go!” and then the pilots run out to their aircraft. But, according to author Lynn Spencer, since the time the group of pilots returned from their training mission, “there has not been time to do much more than fuel their jets.” Most of the base’s fighters “are still unarmed. Despite the furious pace of the weapons handlers, only a handful of jets have been uploaded with some armament.” The first two F-15s that take off from Otis Air Base in response to the NEADS order will both be unarmed (see (10:30 a.m.) September 11, 2001). [Spencer, 2008, pp. 245-246] Another two F-15s will take off shortly after them with their guns loaded, but one of them will have only one missile loaded instead of two (see (Shortly After 10:30 a.m.) September 11, 2001). [Cape Cod Times, 9/11/2006; Richard, 2010, pp. 15-16, 18] Two F-15s that are kept on alert at Otis Air Base took off at 8:46 a.m. in response to the hijacking of Flight 11 (see 8:46 a.m. September 11, 2001).

Joe McGrady.Joe McGrady. [Source: John P. Meyer]Two F-15 fighter jets take off from Otis Air National Guard Base in Cape Cod, Massachusetts, the first to do so after NORAD’s Northeast Air Defense Sector (NEADS) ordered the base to launch all of its available aircraft (see (10:20 a.m.) September 11, 2001). However, these two fighters are unarmed. [9/11 Commission, 10/14/2003 pdf file; Spencer, 2008, pp. 245-246] The 102nd Fighter Wing of the Massachusetts Air National Guard operates from Otis Air Base, and is responsible for defending the northeastern US against various threats, including terrorist attacks. [Cape Cod Times, 9/12/2001; Cape Cod Times, 9/12/2001] The aircraft maintenance squadron officer started preparing the unit’s F-15s for combat less than 15 minutes after the second attack in New York (see (9:15 a.m.) September 11, 2001). [Spencer, 2008, pp. 155] But despite the reportedly “furious pace of the weapons handlers” who “hurried to fix all available jets with live weapons,” only a few fighters have so far been loaded with any armament. [Cape Cod Times, 9/8/2002; Spencer, 2008, pp. 245]
Fighters Launch with No Weapons - The first two fighters to take off are piloted by Dennis Doonan and Joe McGrady. As they are the first pilots to start their F-15s and taxi off the flight line (the parking and servicing area for aircraft), they are paired up. But Doonan suddenly realizes that, though he is being sent into a combat situation, his fighter is unarmed. He radios McGrady and tells him, “I’m Winchester!” (“Winchester” is the code word for having no weapons.) McGrady’s aircraft is also unarmed, so McGrady immediately radios squadron commander Lieutenant Colonel Jon Treacy and in a panic tells him: “We’re Winchester, SOF [supervisor of flying]! We’re Winchester!” But Treacy instructs him: “Just go! You need to get airborne now!” McGrady and Doonan head out for takeoff, not knowing where they are going or what they will have to do, but realizing that if they have to take out a target, they must do so with their own aircraft. Once they are airborne, they will intercept a KC-10 tanker plane and four A-10 jets (see (11:04 a.m.) September 11, 2001), and then set up a combat air patrol over Boston. [Spencer, 2008, pp. 245-247]
Other Fighters Take Off Armed - Another two F-15s will take off from Otis Air Base shortly after McGrady and Doonan’s fighters (see (Shortly After 10:30 a.m.) September 11, 2001). These aircraft will have had their guns loaded and armed for use, but one of them will take off with only one missile loaded instead of two. [Cape Cod Times, 9/11/2006; Richard, 2010, pp. 15-16, 18] The 102nd Fighter Wing’s two F-15s that are kept on “alert”—armed and ready for immediate takeoff—launched at 8:46 a.m., in response to the hijacked Flight 11 (see 8:46 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] Fourteen of the base’s fighters will be “mission capable” by the end of the day, and six fighters will be airborne at a time, according to Technical Sergeant Michael Kelly, the full-time technician in the command post at Otis Air Base.

Two F-15s take off from Otis Air National Guard Base in Massachusetts, becoming the second pair of fighter jets to take off from the base after NORAD’s Northeast Air Defense Sector (NEADS) ordered it to launch all of its available aircraft. [9/11 Commission, 10/14/2003 pdf file; Spencer, 2008, pp. 245-246; Richard, 2010, pp. 18] The fighters belong to the 102nd Fighter Wing, which is based at Otis Air Base, and are piloted by Major Martin Richard and Major Robert Martyn. [102nd Fighter Wing, 2001; Cape Cod Times, 9/11/2006] The 102nd Fighter Wing launched its two F-15s that are kept on “alert”—ready for immediate takeoff—at 8:46 a.m., in response to the hijacked Flight 11 (see 8:46 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] Another two of the unit’s F-15s have just taken off (see (10:30 a.m.) September 11, 2001). [Spencer, 2008, pp. 245-246] Richard is one of several 102nd Fighter Wing pilots who were out for a training mission over the Atlantic Ocean earlier this morning (see (9:00 a.m.-9:24 a.m.) September 11, 2001). The pilots were called back to their base following the attacks in New York (see (9:25 a.m.-9:45 a.m.) September 11, 2001). It is unclear whether Martyn also participated in the training. [Cape Cod Times, 9/11/2006]
Pilot Doesn't Know What Is Going On - After landing back at Otis Air Base, Richard headed into the operations building and phoned his wife. He told her, “I don’t know what’s going on, but I am going flying.” Richard will later recall: “My feelings were of trepidation. I didn’t know what was going on and didn’t know what the two scrambled aircraft [i.e. the two fighters launched from his base in response to Flight 11] were doing.” Richard and Martyn had then been called to the operations desk, where Lieutenant Colonel Jon Treacy, their unit’s supervisor of flying, told them they would be flying two of the first four fighters to be subsequently taking off from the base. [102nd Fighter Wing, 2001; Richard, 2010, pp. 14-15] Around that time, NEADS called the unit and instructed it to launch all of its available fighters, and the pilots had then been sent out to their aircraft (see (10:20 a.m.) September 11, 2001). [Spencer, 2008, pp. 245]
Fighter Only Has One Missile Loaded - When he arrived at his fighter, Richard found Technical Sergeant Matthew Jackson loading the second of two AIM-9 heat-seeking missiles onto it. Dennis Mills, the crew chief, told Richard that his plane was fueled up and had a “hot gun with bullets,” meaning the 20mm gun was loaded and armed for use. Richard, who was impatient to get airborne, instructed Jackson to not bother loading the second missile onto his aircraft.
Intelligence Officer Warns of Eight Suspicious Aircraft - Then, Sergeant Joe Kelleher, the unit’s intelligence specialist, arrived, out of breath. Kelleher said: “There are up to eight airliners airborne with bombs on board. We know of an American [Airlines] jet out of Dulles [International Airport] and a United [Airlines] jet. I think you are going after the United jet.” The United Airlines aircraft he referred to, according to Richard, was Flight 93. [Richard, 2010, pp. 15-16] However, this plane crashed in Pennsylvania 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). [9/11 Commission, 7/24/2004, pp. 30] Richard will comment, “We were finding out real-time what the actual air picture was, and the information was not accurate.” Kelleher continued: “They are turning jets away from Europe and the rumor is some have crashed because they’ve run out of fuel. It’s friggin’ chaos!”
Fighters Take Off from Base - In their fighters, Richard and Martyn now taxi to the runway and take off from Otis Air Base. While climbing to altitude, Richard keeps his fighter’s engines in afterburner so as to gather the most speed he can. [Richard, 2010, pp. 16, 18] Richard and Martyn will be directed to intercept a C-130 military cargo plane (see (After 10:35 a.m.) September 11, 2001), and will subsequently be sent over New York to intercept and identify aircraft there (see (11:00 a.m.-6:00 p.m.) September 11, 2001).

Personnel on the operations floor at NORAD’s Northeast Air Defense Sector (NEADS) are confused over the nature and effect of an order they have received, which states that the military can shoot down aircraft that do not respond to its directions, and they do not pass this order on to fighter pilots under their command. [9/11 Commission, 7/24/2004, pp. 42-43; 9/11 Commission, 8/26/2004, pp. 47; Spencer, 2008, pp. 240-241; Farmer, 2009, pp. 228-229] NEADS has just received a message over the NORAD computer chat system from Larry Arnold, the commander of the Continental United States NORAD Region (CONR), stating that Vice President Dick Cheney has authorized NORAD to shoot down suspicious aircraft (see 10:31 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 42]
Weapons Director Alerted to Order - Major Steve Ovens sees the chat message and alerts Major James Fox, the leader of the NEADS weapons team, to it. Ovens says: “We need to read this. Region commander has declared that we can shoot down tracks that do not respond to our direction. Okay?” Fox replies, “Okay,” but Ovens is unconvinced that he has understood Arnold’s message, so he says again, “The region commander has declared that we can shoot down aircraft that do not respond to our directions, okay?” Fox replies, “Copy that.”
NEADS Director Opposes Order - Ovens continues, “So if you’re trying to divert somebody and he won’t divert…” but Fox says, “DO [the director of operations] is saying no.” According to author Lynn Spencer, Fox means that Colonel Lanny McNeely, the NEADS director of operations, is indicating “no.” McNeely has “understood that the battle staff wanted to keep shootdown authority in the [NEADS] battle cab. The commanders were not prepared to pass such authorizations to airborne fighters.” [North American Aerospace Defense Command, 9/11/2001; Spencer, 2008, pp. 240-241] However, a 9/11 Commission memorandum will state that McNeely is away from NEADS on this day, in Texas, and no one is currently sitting in the director of operations position. [9/11 Commission, 10/30/2003 pdf file] According to John Farmer, the senior counsel to the 9/11 Commission, Fox is instead referring to Colonel Robert Marr, the NEADS battle commander, saying “no,” not McNeely. [Farmer, 2009, pp. 229]
Fox Agrees to Pass on Order to Commander - Ovens responds: “No? It came over the chat.… You got a conflict on that direction?” Fox replies, “Right now, no, but…” Showing Fox the chat message, Ovens says: “Okay. You read that from the vice president, right? Vice president has cleared…” Fox reads the message out loud, saying, “Vice president has cleared us to intercept traffic and shoot them down if they do not respond, per CONR CC.” Finally, he says, “Okay, I will pass it to MCC,” meaning Major Kevin Nasypany, the NEADS mission crew commander. [North American Aerospace Defense Command, 9/11/2001; Spencer, 2008, pp. 241]
NEADS Does Not Pass on Order to Pilots - NEADS personnel will later express to the 9/11 Commission their “considerable confusion over the nature and effect” of this shootdown order, and explain why they fail to pass it on to the fighter jets from Otis Air National Guard Base (see 8:46 a.m. September 11, 2001) and Langley Air Force Base (see 9:24 a.m. September 11, 2001) that are under their command. Nasypany and Fox indicate to the Commission that “they did not pass the order to the fighters circling Washington and New York because they were unsure how the pilots would, or should, proceed with this guidance.” Consequently, “while leaders in Washington believed that the fighters above them had been instructed to ‘take out’ hostile aircraft, the only orders actually conveyed to the pilots were to ‘ID type and tail.’” [9/11 Commission, 7/24/2004, pp. 43; Farmer, 2009, pp. 229]

The press incorrectly reports that an airliner has crashed on or near Camp David. [Daily Record (Baltimore), 9/12/2001; US Department of Transportation, 3/2002] Camp David is the presidential retreat, located about 70 miles north of Washington, DC, in the Catoctin Mountains of Maryland. [Federation of American Scientists, 10/2/2000; Associated Press, 7/30/2007] On Air Force One, at 10:37, White House chief of staff Andrew Card relays to the president the incorrect report of the crash. [Sammon, 2002, pp. 108] At around 11:09, CBS News reports that “a plane apparently has crashed at or near Camp David.” [Broadcasting and Cable, 8/26/2002] An early article by Forbes states, “There are reports of a fourth airliner [having] been brought down near Camp David… by US military fighters.” [Forbes, 9/11/2001] And an early report by the Northwestern Chronicle similarly states, “Air Force officials say an airliner has been forced down by F-16 fighter jets near Camp David.” [Northwestern Chronicle, 9/11/2001] Theresa Hahn, the catering manager for a restaurant in the Camp David area, hears the erroneous report. She subsequently describes, “Lots of fire trucks were on the road and no one can get up there.” But J. Mel Poole, the Catoctin Mountain Park superintendent, states there has been “no crash at Camp David.” [Daily Record (Baltimore), 9/12/2001] At some point, the FAA calls the military to confirm the crash, and is reassured that no crash occurred at Camp David. [Freni, 2003, pp. 42] The actual Flight 93 crash site is about 85 miles northwest of Camp David. [PBS, 9/11/2001] The Secret Service reportedly tells the White House that Flight 93 may have been on a course for Camp David. [Pittsburgh Channel, 9/11/2001] And, following a military briefing, Representative James Moran (D-VA) tells reporters that Flight 93 was apparently heading for Camp David. [Associated Press, 9/11/2001; Wall Street Journal, 9/12/2001] (However, the 9/11 Commission will later state that its intended target was either the White House or the Capitol building. [9/11 Commission, 7/24/2004, pp. 14] ) The source of the incorrect report of the Camp David crash is unclear. However, when the FAA’s Washington Center first informed NEADS that Flight 93 had crashed, at 10:15, it simply reported that it had gone down “somewhere up northeast of Camp David” (see 10:15 a.m. September 11, 2001), so this may have created some of the confusion. [Vanity Fair, 8/1/2006] There are also numerous false reports of terrorist attacks having taken place in Washington, DC around this time (see (Between 9:50-10:40 a.m.) September 11, 2001). Some commentators make the connection that the 9/11 attacks come 23 years after the signing of the Camp David accords—a peace agreement between Israel and Egypt—on September 17, 1978. [Forbes, 9/11/2001; Village Voice, 9/11/2001; Daily Record (Baltimore), 9/12/2001] WCBS reports, “[T]here is speculation that perhaps, perhaps, this may be in retaliation for those accords.” [Broadcasting and Cable, 8/26/2002]

Two F-15 fighter jets from Otis Air National Guard Base, Massachusetts, patrol the airspace over New York, first assisting and then later replacing another pair of F-15s that arrived over the city earlier on. [9/11 Commission, 10/14/2003 pdf file; Cape Cod Times, 9/11/2006; Richard, 2010, pp. 25-26, 88] The two fighters belong to the 102nd Fighter Wing, and are piloted by Major Martin Richard and Major Robert Martyn. They took off from Otis Air Base at around 10:30 a.m. (see (Shortly After 10:30 a.m.) September 11, 2001) and have already intercepted a military cargo plane that was returning to the US from England (see (After 10:35 a.m.) September 11, 2001). [102nd Fighter Wing, 2001; Westover Patriot, 10/2001 pdf file; 9/11 Commission, 10/14/2003 pdf file; Richard, 2010, pp. 18-20]
Fighters Directed toward New York - The fighters were flying southwest toward New York when their pilots received orders from NORAD’s Northeast Air Defense Sector (NEADS), instructing them to “continue southwest and set up a combat air patrol over bull’s-eye.” “Bull’s-eye”—the reference point from which all positional reporting originates—had been set as the location of the now-collapsed World Trade Center towers. The fighters therefore continued toward the city.
FAA's New York Center Does Not Respond to Communication - Richard and Martyn tried checking in with the FAA’s New York Center, but received no reply. NEADS therefore instructed them to instead check in with the FAA’s New York Terminal Radar Approach Control. As they were flying to New York, NEADS also told the two pilots that their mission was “to intercept, divert, or, if unsuccessful in those, to call them for authorization to shoot down” aircraft. Richard will later comment, “That certainly got our attention.” [102nd Fighter Wing, 2001; Richard, 2010, pp. 24]
Fighters Join Two Aircraft Already over New York - Two fighters that took off from Otis Air Base at 8:46 a.m. in response to the hijacked Flight 11 (see 8:46 a.m. September 11, 2001), piloted by Lieutenant Colonel Timothy Duffy and Major Daniel Nash, arrived over New York earlier in the morning (see 9:25 a.m. September 11, 2001 and (9:45 a.m.-10:45 a.m.) September 11, 2001) and established a combat air patrol over the city. [9/11 Commission, 7/24/2004, pp. 20, 24; Boston Globe, 9/11/2005] Richard and Martyn arrive, joining these two fighters over New York, at approximately 11:00 a.m., Nash will say. [9/11 Commission, 10/14/2003 pdf file]
Fighters Set Up a 'Point Defense' around New York - Martyn then calls Duffy over the radio. Referring to his own fighter by its call sign, Martyn says, “Panta one is on station at 15,000 feet.” Duffy instructs him, “Panta one, orbit over bull’s-eye and stand by.” Richard will describe the tactic the four fighters then employ, writing: “Duff decided to set up a point defense around the city.… Ground Zero was our reference point and the targets in the area were called out in reference to it.… Since we were flying in a void of actionable information, we decided that the most effective way to win this battle was to let the enemy come to us.” [Richard, 2010, pp. 25-26] While Duffy and Nash fly about 10,000 feet above New York, Richard and Martyn fly at around 18,000 feet. [Filson, 10/2/2002]
Fighters Intercept and Identify Aircraft - Richard will recall that he and Martyn “darted around the city, chasing down airliners, helicopters, and anything else in the air,” making sure that “everything in the air was visually identified, intercepted, and guided to land at the closest airfield.” [Richard, 2010, pp. 36] They spend several hours identifying helicopters that have no flight plans and are heading for Ground Zero. Many of these helicopters belong to organizations that want to help, and are there to provide relief and aid. [102nd Fighter Wing, 2001; Richard, 2010, pp. 74] When necessary, the two fighters are able to refuel from a KC-135 tanker plane that is orbiting above them at 20,000 feet.
Fighters Replaced by Other Aircraft from Otis Air Base - After Duffy and Nash head back to Otis Air Base (see (2:15 p.m.) September 11, 2001), Richard and Martyn continue clearing the skies over New York and eastern New Jersey. Richard will describe the following few hours as “mostly boredom interspersed with moments of sheer terror.” [Richard, 2010, pp. 72, 74, 88] Richard and Martyn finally return to Otis Air Base at around 6:00 p.m. [102nd Fighter Wing, 2001] Another two F-15s belonging to the 102nd Fighter Wing take their place patrolling the airspace above New York. These fighters are flown by pilots that Richard will only refer to by their nicknames, “Psycho Davis” and “Doo Dah Ray.” These pilots participated, along with Richard, in a training mission over the Atlantic Ocean early this morning (see (9:00 a.m.-9:24 a.m.) September 11, 2001).

The two F-15 fighter jets that launched from Otis Air National Guard Base in Cape Cod, Massachusetts, in response to the hijacked Flight 11 (see 8:46 a.m. September 11, 2001) land back at their base after flying a combat air patrol (CAP) over New York City. [Aviation Week and Space Technology, 6/3/2002; Filson, 10/2/2002] The F-15s, which belong to the 102nd Fighter Wing of the Massachusetts Air National Guard, are piloted by Major Daniel Nash and Lieutenant Colonel Timothy Duffy. [Rosenfeld and Gross, 2007, pp. 35]
Fighters Intercepted about 100 Aircraft - Duffy and Nash’s job during the CAP was to identify and divert all aircraft from the Manhattan area. Duffy will later recall, “We would pull up next to them and tip our wings or fly across in front of them to get them to leave the area.” [102nd Fighter Wing, 2001; 9/11 Commission, 1/7/2004 pdf file] He will say that during their time flying over Manhattan, “All of the sudden, you get contacts coming toward the city that are unidentified and aren’t talking to anybody, and we were getting real nervous.” [Filson, 10/22/2002] Duffy will estimate that the two fighters intercepted and escorted about 100 aircraft in total, including emergency, military, and news helicopters, plus dozens of small private planes whose pilots were unaware of the attacks on New York. Some of those pilots had seen the smoke over the city and decided to investigate. [Aviation Week and Space Technology, 6/3/2002; Cape Cod Times, 8/21/2002]
One Fighter over Manhattan at All Times - Duffy and Nash had alternated their responsibilities, so that one of them would remain over Manhattan at all times while the other would intercept aircraft or be refueled by a tanker plane over the ocean (see (Shortly After 9:35 a.m.) September 11, 2001). After flying the CAP for about two hours, they were joined by a couple more F-15s from Otis Air Base (see (11:00 a.m.-6:00 p.m.) September 11, 2001). While those jets flew at around 18,000 feet, Nash and Duffy remained at around 10,000 feet. [Cape Cod Times, 8/21/2002; Filson, 10/2/2002; Filson, 10/22/2002; 9/11 Commission, 1/7/2004 pdf file] Eventually, after several hours flying over Manhattan, Nash and Duffy were ordered to return to their base.
Base Hectic with Activity - Upon landing, they find that Otis Air Base is very different to how it was when they took off. Rows and rows of their unit’s fighters are lined up near the runway, surrounded by about 100 maintenance personnel who are frantically working to prepare the aircraft for battle. [Spencer, 2008, pp. 273-274] Armed security officers in flak jackets are guarding every entrance to the base; personnel are swarming in the buildings; and officers are trying to locate all the reserve pilots.
Pilot Learns of Pentagon Attack - The two fighter pilots had been poorly informed about what was going on regarding the terrorist attacks, and were only told in passing by an air traffic controller that there had been an attack in Washington (see (8:53 a.m.-10:30 a.m.) September 11, 2001). After he gets out of his plane, Nash is informed by a crew member that an aircraft crashed into the Pentagon. [Cape Cod Times, 8/21/2002; Michael Bronner, 2006] Nash and Duffy subsequently go to their unit’s “intelligence shop” and describe what they have done since taking off from the base hours earlier.

One of the pilots of the two F-15s from the 102nd Fighter Wing that took off in response to the hijacked Flight 11 (see 8:46 a.m. September 11, 2001) is told by a colleague that the military has shot down an aircraft over Pennsylvania. After the fighter pilots, Major Daniel Nash and Lieutenant Colonel Timothy Duffy, land at Otis Air National Guard Base in Cape Cod, Massachusetts, having spent the past few hours flying a combat air patrol over New York (see (2:15 p.m.) September 11, 2001), a “bunch of people” at the base start telling them “what was going on,” Nash will later recall. A crew chief tells Nash that an F-16 fighter jet shot down a fourth airliner over Pennsylvania. Nash will comment, “Obviously that wasn’t true, so there were lots of rumors floating around.” [Cape Cod Times, 8/21/2002; Filson, 10/2/2002] Some early news reports suggested the possibility of a plane having been shot down by the US military (see 11:28 a.m.-11:50 a.m. September 11, 2001). [Forbes, 9/11/2001; TCM Breaking News, 9/11/2001] But the Pentagon has by now informed the White House that the military did not shoot down Flight 93 over Pennsylvania (see (Shortly After 12:00 p.m.) September 11, 2001).

Carl Levin.Carl Levin. [Source: Publicity photo]Air Force General Richard Myers is questioned about the US military’s response to the 9/11 attacks when he appears before the Senate Armed Services Committee for his confirmation hearing as chairman of the Joint Chiefs of Staff, but his answers are vague and confused, and he claims, incorrectly, that no fighter jets were scrambled in response to the hijackings until after the Pentagon was hit. [Shenon, 2008, pp. 119; Farmer, 2009, pp. 241-243] Myers has been the vice chairman of the Joint Chiefs of Staff since March 2000. [US Air Force, 9/2005] With General Henry Shelton, the chairman of the Joint Chiefs of Staff, flying toward Europe on the morning of September 11 (see (8:50 a.m.-10:00 a.m.) September 11, 2001), he served as the acting chairman of the Joint Chiefs of Staff during the 9/11 attacks. [Myers, 2009, pp. 10; Shelton, Levinson, and McConnell, 2010, pp. 431-433]
Myers Says Fighters Were Only Scrambled after the Pentagon Attack - During the hearing, Senator Carl Levin (D-MI) asks if the Department of Defense was contacted by “the FAA or the FBI or any other agency” after the first two hijacked aircraft crashed into the World Trade Center, at 8:46 a.m. and 9:03 a.m. (see 8:46 a.m. September 11, 2001 and 9:03 a.m. September 11, 2001), but before 9:37 a.m., when the Pentagon was hit (see 9:37 a.m. September 11, 2001). Myers replies, “I don’t know the answer to that question.” Levin then asks if the military was “asked to take action against any specific aircraft” during the attacks. Myers answers, “When it became clear what the threat was, we did scramble fighter aircraft, AWACS, radar aircraft, and tanker aircraft to begin to establish orbits in case other aircraft showed up in the FAA system that were hijacked.” Myers elaborates later in the hearing, telling Senator Bill Nelson (D-FL): “[A]fter the second tower was hit, I spoke to the commander of NORAD, General [Ralph] Eberhart (see (9:37 a.m.) September 11, 2001). And at that point, I think the decision was at that point to start launching aircraft.” But he tells Levin that “to the best of my knowledge,” the order to scramble fighters was only given “after the Pentagon was struck.”
Flight 93 Was Not Shot Down, Myers Says - Myers addresses the military’s response to Flight 93, the fourth hijacked plane, which crashed in a field in Pennsylvania (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001). He says: “[I]f my memory serves me… we had launched on the one that eventually crashed in Pennsylvania. I mean, we had gotten somebody close to it, as I recall.” However, he adds, “I’ll have to check that out.” When Levin mentions that there have been “statements that the aircraft that crashed in Pennsylvania was shot down,” Myers responds, “[T]he armed forces did not shoot down any aircraft.” He says, “[W]e never actually had to use force.” Although Myers appears unclear about when the North American Aerospace Defense Command (NORAD) launched fighters in response to the hijackings, he is more confident when he states: “At the time of the first impact on the World Trade Center, we stood up our Crisis Action Team. That was done immediately. So we stood it up. And we started talking to the federal agencies.” [US Congress, 9/13/2001]
NORAD and the 9/11 Commission Contradict Myers's Account - Myers’s claim that fighters were only launched in response to the hijackings after the Pentagon was hit will later be contradicted by the accounts of NORAD and the 9/11 Commission, which state that fighters were ordered to take off from Otis Air National Guard Base in Cape Cod, Massachusetts, at 8:46 a.m. (see 8:46 a.m. September 11, 2001) and from Langley Air Force Base in Virginia at 9:24 a.m. (see 9:24 a.m. September 11, 2001). [North American Aerospace Defense Command, 9/18/2001; 9/11 Commission, 7/24/2004, pp. 20, 27] The 9/11 Commission will also contradict Myers’s claim that the military launched fighters in response to Flight 93 and “had gotten somebody close to it.” “By the time the military learned about the flight,” the 9/11 Commission Report will state, “it had crashed.” [9/11 Commission, 7/24/2004, pp. 34]
Myers's Testimony Prompts Criticism in the Media - Journalist and author Philip Shenon will question why Myers, a veteran Air Force fighter pilot, would give such an inaccurate account of the military’s response to the 9/11 attacks during the hearing. “It seemed obvious that Myers, of all people at the Pentagon, would want to know—would demand to know—how jet fighters under NORAD’s control had responded on the morning of September 11 to the threat in the skies,” he will write. [US Congress, 9/13/2001; Shenon, 2008, pp. 119] John Farmer, the senior counsel to the 9/11 Commission, will comment that “Myers’s evident confusion about precisely what had occurred prompted criticism in the media and a quick, if contradictory, response from the administration.” [Farmer, 2009, pp. 243] Major General Paul Weaver, director of the Air National Guard, will provide a more detailed account of the military’s response to the hijackings in an “impromptu hallway interview” at the Pentagon on September 14 (see September 14, 2001). [Dallas Morning News, 9/14/2001] And four days later, NORAD will release a timeline of its response to the hijackings (see September 18, 2001). [North American Aerospace Defense Command, 9/18/2001]

Major General Paul Weaver, director of the Air National Guard, provides reporters with details of the 9/11 attacks and the US military’s response to the hijackings. Speaking at the Pentagon, Weaver gives reporters a detailed account of what happened on September 11. He says Air National Guard planes responded to the hijackings on orders from NORAD’s Northeast Air Defense Sector (NEADS), which was alerted to the hijackings by the Federal Aviation Administration (FAA).
Fighters Took Off Too Late to Catch Flight 175 - Weaver says that at 8:53 a.m., seven minutes after Flight 11 crashed into the North Tower of the World Trade Center (see 8:46 a.m. September 11, 2001), two F-15 fighter jets took off from Otis Air National Guard Base in Cape Cod, Massachusetts, in pursuit of Flight 175, the second plane to be hijacked (see 8:46 a.m. September 11, 2001 and 8:53 a.m. September 11, 2001). However, Weaver says, the FAA had only told NEADS that “there was an airplane that had a problem,” and at that time it was unclear if Flight 175 had been hijacked. He says that although the fighters flew at over 500 miles per hour, they were unable to catch up with Flight 175 before it hit the South Tower of the WTC at 9:03 a.m. (see 9:03 a.m. September 11, 2001).
More Fighters Were Launched Just before Pentagon Was Hit - Weaver says Flight 77, the third aircraft to be hijacked, flew west for 45 minutes and then turned east, and its transponder was turned off. He does not claim that the military received notice that it had been hijacked, but says NEADS scrambled F-16 fighters that were on alert at Langley Air Force Base in Virginia at 9:35 a.m. (see 9:24 a.m. September 11, 2001 and (9:25 a.m.-9:30 a.m.) September 11, 2001). Two minutes later, at 9:37 a.m., the Pentagon was hit (see 9:37 a.m. September 11, 2001). The F-16s, he says, subsequently remained on patrol over the Pentagon.
No Fighters Took Off to Intercept Flight 93 - Weaver says no fighters were scrambled to chase after Flight 93, the fourth hijacked plane, which crashed in a field in Pennsylvania (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001). “There was no notification for us to launch airplanes,” he tells the reporters. “We weren’t even close.” [Dallas Morning News, 9/14/2001; Farmer, 2009, pp. 244] (However, also on this day, Deputy Defense Secretary Paul Wolfowitz contradicts Weaver’s claim. He tells PBS’s NewsHour, “[W]e were already tracking in on that plane that crashed in Pennsylvania,” and adds, “[T]he Air Force was in a position to do so [i.e. shoot Flight 93 down] if we had had to.” [NewsHour with Jim Lehrer, 9/14/2001; Farmer, 2009, pp. 245] ) Weaver says that even if fighters had caught up with the hijacked planes, they may have been unable to stop them reaching their targets. “You’re not going to get an American pilot shooting down an American airliner,” he says. “We don’t have permission to do that.” According to Weaver, only the president can issue an order to shoot down an American airliner. [Dallas Morning News, 9/14/2001]
Weaver's Account Is the 'Most Accurate' Prior to the 9/11 Commission's Investigation - The account he gives to reporters today, according to John Farmer, the senior counsel to the 9/11 Commission, will be “the last public statement uttered by General Weaver on the subject and proved to be the most accurate account of events issued until the 9/11 Commission’s investigation.” [Farmer, 2009, pp. 245] Apparently after Weaver issues his statement to the reporters, an Air Force spokesman, speaking on condition of anonymity, adds that no regular Air Force planes were scrambled during the 9/11 attacks, “because continental air defense is the mission of the Air National Guard.” He says regular Air Force fighters “have air superiority as their mission,” which means they train “to deploy somewhere where we are engaged in hostile action and secure the skies.” These fighters, according to the spokesman, “ordinarily are not ready to fly on short notice and their pilots are not on standby to defend the United States.” [Dallas Morning News, 9/14/2001]
Pentagon Has Been Slow to Answer Questions about Response to Hijackings - The Washington Post will comment, “Questions about the time it took US military planes to respond to the threat of several hijacked aircraft speeding toward the nation’s financial and military centers have dogged the Pentagon since the attacks.” It will add, “Top Pentagon officials have been slow to respond to press inquiries for a timeline that would establish the exact times that civil aviation authorities became aware of the hijackings, when US military commanders were notified, and when US fighter jets took to the air.” [Washington Post, 9/15/2001] The previous day, Air Force General Richard Myers was questioned about the military’s response to the attacks before the Senate Armed Services Committee, but his answers were vague and confused (see September 13, 2001). [US Congress, 9/13/2001; Farmer, 2009, pp. 241-242] NORAD will release its own timeline of the events of September 11 and its response to the hijackings on September 18 (see September 18, 2001).

The Federal Aviation Administration (FAA) produces a chronology of the events of September 11, which it uses when it briefs the White House today, but the document fails to mention when NORAD’s Northeast Air Defense Sector (NEADS) was alerted to two of the hijacked planes. The FAA’s chronology, titled “Summary of Air Traffic Hijack Events,” incorporates “information contained in the NEADS logs, which had been forwarded, and on transcripts obtained from the FAA’s Cleveland Center, among others,” according to John Farmer, the senior counsel to the 9/11 Commission.
Document Includes Notification Times for First Two Hijacked Flights - The chronology refers “accurately to the times shown in NEADS logs for the initial notifications from FAA about the hijacking of American 11 and the possible hijacking of United 175,” according to the 9/11 Commission. It gives 8:40 a.m. as the time at which the FAA alerted NEADS to Flight 11, the first plane to be hijacked (see (8:37 a.m.) September 11, 2001), and 9:05 a.m. as the time when the FAA alerted NEADS to Flight 175, the second plane to be hijacked (see (9:03 a.m.) September 11, 2001). However, it makes no mention of when the FAA alerted NEADS to Flight 77 and Flight 93, the third and fourth planes to be hijacked. The FAA’s omission of these two notification times is “suspicious,” according to the 9/11 Commission, “because these are the two flights where FAA’s notification to NEADS was significantly delayed.”
Document Omits Notification Times for Flights 77 and 93 - The chronology, as Farmer will later point out, “makes no mention… of the notification to NEADS at 9:33 that American 77 was ‘lost’ (see 9:34 a.m. September 11, 2001) or of the notification to NEADS at 9:34 of an unidentified large plane six miles southwest of the White House (see 9:36 a.m. September 11, 2001), both of which are in the NEADS logs that the FAA reviewed” when it was putting together the timeline. It also fails to mention the call made by the FAA’s Cleveland Center to NEADS in which, at 10:07 a.m., the caller alerted NEADS to Flight 93 and said there was a “bomb on board” the plane (see 10:05 a.m.-10:08 a.m. September 11, 2001), even though this information was also “duly noted in the NEADS logs” that the FAA has reviewed.
Chronology Omits Other Key Information - The chronology, Farmer will write, reflects “a time at which the FAA was notified that the Otis [Air National Guard Base] fighters were scrambled” in response to the hijacking of Flight 11 (see 8:46 a.m. September 11, 2001), but it gives “no account of the scramble of the fighters from Langley Air Force Base” (see 9:24 a.m. September 11, 2001). It also fails to mention the report that NEADS received after Flight 11 crashed, in which it was incorrectly told the plane was still airborne and heading toward Washington, DC (see 9:21 a.m. September 11, 2001). Despite lacking information about the times when the FAA alerted NEADS to Flights 77 and 93, the FAA’s chronology is one of the documents used to brief the White House about the 9/11 attacks today (see September 17, 2001).
Investigators Were Told to Determine Exact Notification Times - The chronology is the product of investigations that began promptly in response to the 9/11 attacks. According to senior FAA officials, FAA Administrator Jane Garvey and Deputy Administrator Monte Belger “instructed a group of FAA employees (an ‘after-action group’) to reconstruct the events of 9/11.” This group, according to the 9/11 Commission, “began its work immediately after 9/11 and reviewed tape recordings, transcripts, handwritten notes, logs, and other documents in an effort to create an FAA chronology of events.” The group, according to one witness, “was specifically asked to determine exactly when the FAA notified the military that each of the four planes had been hijacked,” and “[s]everal people worked on determining correct times for FAA notifications to the military.” [Federal Aviation Administration, 9/17/2001 pdf file; 9/11 Commission, 7/29/2004; Farmer, 2009, pp. 245-247] NORAD will release a timeline of the events of September 11 and its response to the attacks a day after the FAA chronology is published (see September 18, 2001).

The North American Aerospace Defense Command (NORAD) releases a chronology of the events of September 11 and its response to the terrorist attacks that day, but the accuracy of this account will later be challenged by the 9/11 Commission. [North American Aerospace Defense Command, 9/18/2001; 9/11 Commission, 7/24/2004, pp. 34; 9/11 Commission, 7/29/2004]
NORAD Learned of First Hijackings Too Late to Defend the WTC - The chronology provides the times at which NORAD’s Northeast Air Defense Sector (NEADS) was alerted to the hijackings and when fighter jets were scrambled in response to the hijackings. It states that the Federal Aviation Administration (FAA) notified NEADS about Flight 11, the first hijacked aircraft, at 8:40 a.m. In response, the order was given to scramble two F-15 fighters from Otis Air National Guard Base in Cape Cod, Massachusetts, at 8:46 a.m. (see 8:46 a.m. September 11, 2001), the same time that Flight 11 crashed into the World Trade Center (see 8:46 a.m. September 11, 2001), and the fighters were airborne at 8:52 a.m. (see 8:53 a.m. September 11, 2001). The FAA notified NEADS about Flight 175, the second hijacked aircraft, at 8:43 a.m., according to the chronology. When Flight 175 crashed into the WTC at 9:03 a.m. (see 9:03 a.m. September 11, 2001), the chronology states, the Otis fighters were 71 miles away from New York.
Fighters Were Scrambled in Response to Flight 77 Hijacking - NEADS was alerted to Flight 77, the third hijacked aircraft, at 9:24 a.m., according to the chronology. In response, the order was given to scramble two F-16 fighters from Langley Air Force Base in Virginia (see 9:24 a.m. September 11, 2001) and these were airborne at 9:30 a.m. (see (9:25 a.m.-9:30 a.m.) September 11, 2001). But the F-16s were 105 miles from the Pentagon when it was hit at 9:37 a.m. (see 9:37 a.m. September 11, 2001). Regarding the fourth hijacked aircraft, Flight 93, the chronology gives “N/A” as the time the FAA alerted NEADS, but it also states that the FAA and NEADS discussed the flight on “a line of open communication.” At 10:03 a.m., when Flight 93 crashed in Pennsylvania (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001), the chronology states, the F-16s launched from Langley Air Force Base in response to the hijacking of Flight 77 were “in place to protect DC.” [North American Aerospace Defense Command, 9/18/2001]
9/11 Commission Disputes NORAD's Account - The 9/11 Commission Report, released in 2004, will highlight what it says are inaccuracies in NORAD’s timeline of the events of September 11. It will state that NORAD’s claim that NEADS was alerted to Flight 77 at 9:24 a.m. was incorrect. The notice NEADS received at that time, according to the report, was the incorrect claim that Flight 11 “had not hit the World Trade Center and was heading for Washington, DC” (see 9:21 a.m. September 11, 2001). “NEADS never received notice that American 77 was hijacked,” the report will state. “It was notified at 9:34 that American 77 was lost (see 9:34 a.m. September 11, 2001). Then, minutes later, NEADS was told that an unknown plane was six miles southwest of the White House” (see 9:36 a.m. September 11, 2001). The report will state that NORAD’s claim that the Langley fighters were scrambled in response to the notification about Flight 77 is also incorrect. Instead, it will state, the fighters were scrambled in response to the incorrect report that Flight 11 was still airborne and heading south. [9/11 Commission, 7/24/2004, pp. 34]
9/11 Commission Disputes NORAD's Account regarding Flights 175 and 93 - Furthermore, whereas NORAD’s chronology claims that NEADS discussed Flight 93 with the FAA on “a line of open communication,” the 9/11 Commission Report will state that NEADS “first received a call about United 93 from the military liaison at [the FAA’s] Cleveland Center at 10:07,” by which time the plane “had already crashed” (see 10:05 a.m.-10:08 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 30] And while NORAD states that the FAA notified NEADS about Flight 175 at 8:43 a.m., according to the report, the first notification came “in a phone call from [the FAA’s] New York Center to NEADS at 9:03” (see (9:03 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 23]
Military Has Been Slow to Provide Details of Its Response on September 11 - US military officials, according to the Washington Post, “have been slow to respond to press inquiries for a timeline that would establish the exact times that civil aviation authorities became aware of the hijackings, when US military commanders were notified, and when US fighter jets took to the air.” [Washington Post, 9/15/2001] On September 13, Air Force General Richard Myers was questioned about the military’s response to the 9/11 attacks before the Senate Armed Services Committee, but his answers were vague and confused (see September 13, 2001). [US Congress, 9/13/2001; Farmer, 2009, pp. 241-242] A day later, Major General Paul Weaver, director of the Air National Guard, provided reporters with details of the military’s response to the hijackings in an “impromptu hallway interview” at the Pentagon (see September 14, 2001).

Wayne Allard.Wayne Allard. [Source: Publicity photo]General Ralph Eberhart, the commander of the North American Aerospace Defense Command (NORAD), appears before the Senate Armed Services Committee and gives NORAD’s account of the events of September 11 and the military’s response to the terrorist attacks that day, but the 9/11 Commission will later find that some of the information he provides is incorrect. [US Congress. Senate, 10/25/2001; 9/11 Commission, 7/29/2004; Farmer, 2009, pp. 248] Eberhart was at NORAD headquarters at Peterson Air Force Base, Colorado, and then went to NORAD’s operations center in Cheyenne Mountain when the 9/11 attacks were taking place. [9/11 Commission, 3/1/2004 pdf file; 9/11 Commission, 3/1/2004] NORAD released a timeline of its response to the hijackings on September 18 (see September 18, 2001) and Eberhart’s testimony is consistent with that account. [North American Aerospace Defense Command, 9/18/2001]
Eberhart Says Fighters Were Scrambled in Response to First Hijacking - During the hearing, Eberhart tells Senator Wayne Allard (R-CO) that after the Federal Aviation Administration (FAA) alerted NORAD to the first hijacking, of Flight 11 (see (8:37 a.m.) September 11, 2001), NORAD ordered two F-15 fighter jets to take off from Otis Air National Guard Base in Cape Cod, Massachusetts (see 8:46 a.m. September 11, 2001), “almost simultaneously to the first crash” at the World Trade Center (see 8:46 a.m. September 11, 2001). Eberhart says that after he learned a plane had hit the WTC, he was initially unsure if that plane was Flight 11. “I’m sitting there hoping that someone has made a mistake; there has been an accident; that this isn’t the hijacked airplane [that hit the WTC], because there is confusion,” he recalls. He says he was informed that “it was a light commuter airplane” that hit the WTC, although, he says, it “didn’t look like that was caused by a light commuter airplane.”
Fighters Didn't Have Enough Time to Stop Second Crash - Eberhart says the FAA notified NORAD that there was “a second hijacked plane”—referring to Flight 175—“somewhere in there,” but although the Otis fighters were “flying toward New York” after being scrambled, they were still eight minutes away from the city when Flight 175 crashed into the WTC at 9:03 a.m. (see 9:03 a.m. September 11, 2001). “Tragically, there was just too much distance between Otis and New York City to get there in time,” Eberhart comments.
Eberhart Says NORAD Learned Flight 77 Was Hijacked before It Crashed - Eberhart says the first documented instance NORAD has of the FAA notifying it about Flight 77, the third aircraft to be hijacked, was at 9:24 a.m. After the hearing, in responses submitted for the record, Eberhart adds that the FAA notified NORAD’s Northeast Air Defense Sector (NEADS) that Flight 77 “was headed towards Washington, DC.” NEADS, he states, “then passed this information to NORAD’s Air Warning Center and Command Center in Cheyenne Mountain, and to the Continental US NORAD Region’s Regional Air Operations Center.”
Fighters Were Scrambled Too Late to Prevent the Pentagon Attack - Eberhart says NORAD launched two F-16 fighters from Langley Air Force Base in Virginia “as soon as” the FAA alerted it to the hijacking of Flight 77 (see 9:24 a.m. September 11, 2001). However, he says, these fighters were still “approximately 13 minutes away from Washington, DC, when that tragic crash [at the Pentagon] occurred.”
Eberhart Is Unaware of Reason for FAA's Delay in Contacting NORAD - Senator Carl Levin (D-MI) tells Eberhart: “The timeline that we’ve been given is that at 8:55 on September 11, American Airlines Flight 77 began turning east, away from its intended course. And at 9:10, Flight 77 was detected by the FAA radar over West Virginia heading east. That was after the two planes had struck the World Trade Center towers. Then 15 minutes later, at 9:25, the FAA notified NORAD that Flight 77 was headed toward Washington.” In light of this, he asks, “[D]o you know why it took 15 minutes for the FAA to notify NORAD?” Eberhart replies: “I do not know, sir, why it took that amount of time for FAA. I hate to say it, but you’ll have to ask FAA.” Senator John Warner (R-VA), who has an extensive military background, tells Eberhart he is “a little bit stunned that you don’t know why that delay occurred.” He continues, saying, “I would have thought by now all of you in this chain would have gone back, rehearsed these things, figured out what happened, what went wrong, so that we ensure it won’t happen again.” In his responses submitted for the record, Eberhart suggests possible reasons for the delay, stating that after the FAA lost radar contact with Flight 77, it “began to receive calls from outside agencies with reports of a possible downed aircraft. Additionally, the loss of radio contact with the aircraft added to the confusion.” Consequently, he states, “I believe the FAA was faced with conflicting information, which hindered them from making an accurate assessment of the actual location of the aircraft.”
Eberhart Says NORAD Was Following Flight 93 before It Crashed - Eberhart says NORAD was aware of the problems with Flight 93, the fourth hijacked plane, before it crashed in Pennsylvania (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001). He tells Allard that the FAA “knew before it deviated its flight pattern” that Flight 93 “was hijacked.” He says NORAD had been “trying to decide, initially, if that flight was going to continue west and if there was some other target for that flight. Was it Chicago? Was it St. Louis? And what might we do to launch an aircraft to intercept it.” But he says that after the FAA reacquired Flight 93 on radar, NORAD thought the plane “was headed probably for Washington, DC, but maybe New York.” He says NORAD decided at that time to keep the Otis and Langley fighters in place over New York and Washington. If another suspicious plane was approaching, he says, “our intent was to go out and meet that aircraft and destroy it if we needed to, if it entered either Washington, DC, or New York City airspace.” However, in his responses submitted for the record, Eberhart states that the “data/log entries received by NORAD from the FAA [after September 11] do not show a time or entry indicating the FAA specifically notified the Pentagon that United Airlines Flight 93 was hijacked.” He also states that NORAD “did not notify” the National Military Command Center (NMCC) at the Pentagon that Flight 93 had been hijacked.
9/11 Commission Disputes Some of Eberhart's Claims - Several claims Eberhart makes in the hearing will be contradicted by evidence uncovered by the 9/11 Commission during its investigation of the terrorist attacks. Whereas Eberhart says the military was first notified about the hijacking of Flight 77 at 9:24 a.m. and implies that this notification prompted the scrambling of fighters from Langley Air Force Base, according to John Farmer, the senior counsel to the 9/11 Commission, “[T]he first notification regarding American 77 occurred at 9:34, when it was reported ‘lost’” (see 9:34 a.m. September 11, 2001). [US Congress. Senate, 10/25/2001; Farmer, 2009, pp. 248-254] The notice NEADS received at 9:24 a.m., according to the 9/11 Commission Report, was the incorrect claim that Flight 11 “had not hit the World Trade Center and was heading for Washington, DC” (see 9:21 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 34] Consequently, Farmer will write, “the scramble of the Langley fighters did occur as an immediate reaction to a notification about hijacking, but that notification was not, as [Eberhart’s] testimony implies, a report that American 77 was hijacked, but the report that American 11 was still airborne and heading for Washington.” And while Eberhart claims the FAA told NEADS that Flight 77 was heading toward Washington, according to Farmer: “The FAA never notified NEADS that American 77 was heading for Washington, DC. There is no such notification recorded on any tape or in any log maintained at NEADS or at NORAD.” Furthermore, while Eberhart claims the military was following Flight 93 on radar before it crashed and was in position to shoot it down if it approached Washington, Farmer will write that “in fact, NEADS never located United 93 on radar, because the plane had already crashed by the time NEADS was notified.” [Farmer, 2009, pp. 251, 254-255]
