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

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

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

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

A military instruction is issued by the chairman of the Joint Chiefs of Staff, outlining the procedure for dealing with hijackings within the United States. The instruction, titled “Aircraft Piracy (Hijacking) and Destruction of Derelict Airborne Objects,” states that “the administrator, Federal Aviation Administration (FAA), has exclusive responsibility to direct law enforcement activity related to actual or attempted aircraft piracy (hijacking) in the ‘special aircraft jurisdiction’ of the United States. When requested by the administrator, Department of Defense will provide assistance to these law enforcement efforts.” It adds that the National Military Command Center (NMCC) within the Pentagon “is the focal point within Department of Defense for providing assistance. In the event of a hijacking, the NMCC will be notified by the most expeditious means by the FAA. The NMCC will, with the exception of immediate responses as authorized by reference d, forward requests for DOD assistance to the secretary of defense for approval.” [US Department of Defense, 6/1/2001 pdf file] Some will later assume that this requirement for defense secretary approval was new with this instruction. [New York Observer, 6/20/2004] But it has in fact been a requirement since 1997, when the previous instruction was issued, if not earlier. [US Department of Defense, 7/31/1997 pdf file] Although the defense secretary has this responsibility, the 9/11 Commission will conclude that, on the day of 9/11, the “secretary of defense did not enter the chain of command until the morning’s key events were over.” [9/11 Commission, 7/24/2004, pp. 15 pdf file] Secretary of Defense Donald Rumsfeld will later claim that, up to 9/11, terrorism and domestic hijackings were “a law enforcement issue.” [9/11 Commission, 3/23/2004; PBS, 3/25/2004; US Department of Defense, 6/14/2005]

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.

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

The North American Aerospace Defense Command (NORAD), which is responsible for detecting and responding to any attack on the mainland United States, is in the early stages of a major training exercise called Vigilant Guardian that is to take place off the shores of the northeastern US and Canada. The exercise is not scheduled to really take off until the following day, September 11 (see (6:30 a.m.) September 11, 2001), but simulated intelligence briefings and meetings are now being held to set the stage for the mock engagements to come. According to author Lynn Spencer, Vigilant Guardian “is the kind of war game that the Russians usually respond to, even in this post-Cold War era.” The Russians have in fact announced that they will be deploying aircraft to several of their “Northern Tier” bases on September 11. Russian jets have penetrated North American airspace during previous NORAD exercises, and Colonel Robert Marr, the commander of NORAD’s Northeast Air Defense Sector (NEADS), has prepared for them to do so again during the current exercise. If this happens, armed US fighter jets will intercept the Russian aircraft and escort them back to their own territory. In case there is any confrontation, Marr has ordered that his alert fighter jets be loaded with additional fuel and weapons. According to Spencer, on September 11, all alert fighters will be “loaded with live missiles in anticipation of any show of force that might be needed to respond to the Russians.” [Spencer, 2008, pp. 3-5] NORAD has already announced that it is deploying fighters to Alaska and Northern Canada to monitor a Russian air force exercise being conducted in the Russian Arctic and North Pacific Ocean throughout this week (see September 9, 2001). [BBC, 2001, pp. 161; North American Aerospace Defense Command, 9/9/2001] According to the 9/11 Commission, the Vigilant Guardian exercise will in fact postulate “a bomber attack from the former Soviet Union.” [9/11 Commission, 7/24/2004, pp. 458]

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. [Denver Post, 8/28/2011]
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). [North American Aerospace Defense Command, 9/9/2001] The battle staff members in Cheyenne Mountain are positioned to deal with both this operation and the exercise.

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]

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

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

The battle cab at NORAD’s Northeast Air Defense Sector (NEADS) is staffed this morning due to the sector’s participation in the training exercise, Vigilant Guardian. [9/11 Commission, 10/28/2003 pdf file; 9/11 Commission, 10/30/2003 pdf file; Jones, 2011, pp. 24] The battle cab is a glass-walled command area that overlooks the NEADS operations floor. [Filson, 2003, pp. 55; 9/11 Commission, 7/24/2004, pp. 460] The “battle staff”—presumably the personnel working in it—is only formed when a training exercise or an “air defense event” is underway, according to Lieutenant Colonel Dawne Deskins, who is on duty in the battle cab. [9/11 Commission, 10/30/2003 pdf file] Because NEADS is currently participating in an exercise, therefore, the battle cab is manned this morning. [9/11 Commission, 10/30/2003 pdf file] “If the exercise had not been planned, there would not have been any staffing in the battle cab,” Lieutenant Colonel Ian Sanderson, who is also in the battle cab this morning, will later say. He will add that if a battle cab has not already been formed and is required, it would be necessary to call the NEADS director of operations in order to arrange for one to be set up. Forming a battle cab would only take a few minutes once it is understood that a serious incident is taking place, according to Sanderson. Sanderson will comment that if the battle staff had not already been in place when the terrorist attacks began this morning, the NEADS operations floor would still have functioned the same way. But the advantage of already having the battle staff in place is that “key figures of authority [are] there and ready to respond” when NEADS learns of the crisis. [9/11 Commission, 10/29/2003 pdf file] Vigilant Guardian is a major annual air defense exercise simulating an attack on the United States (see (6:30 a.m.) September 11, 2001). Across NORAD, “from Alaska to Canada and throughout the continental United States,” author Leslie Filson will describe, “battle staffs [are] poised to fight the simulated air war” this morning, due to their participation in it.

John Hartling.John Hartling. [Source: NBC News]By 8:34 a.m., Flight 11 has entered airspace managed by Boston Center air traffic controller John Hartling. [MSNBC, 9/11/2002; 9/11 Commission, 7/24/2004, pp. 19] Although Boston controller Pete Zalewski, who was managing Flight 11, concluded the plane was hijacked almost ten minutes earlier (see (8:25 a.m.) September 11, 2001), at the time the blip for Flight 11 appears on Hartling’s radar screen, Hartling is unaware that a hijacking is taking place. According to author Lynn Spencer, the reason is that “The concentration required for the job is so intense that controllers operate on a need-to-know basis. They don’t need to know what’s happening in other controllers’ sectors unless it might affect their own airspace, and distractions are rigorously kept to a minimum.” Tom Roberts, another Boston Center controller, has just been relieved from duty for a scheduled coffee break, and comes over to Hartling’s desk. Referring to Flight 11’s radar track, he tells Hartling, “This—this aircraft, we believe, is hijacked, and he’s last reported at 29,000 feet.” However, Hartling is incredulous. He will later recall that when Roberts says the plane is hijacked, “I didn’t believe him.” This is because “I didn’t think that that stuff would happen anymore, especially in this country.” Hartling continues tracking Flight 11 as it heads toward New York. Although its transponder has been turned off (see (Between 8:13 a.m. and 8:21 a.m.) September 11, 2001), he can tell that, at almost 600 mph, it is flying far faster than the 450 mph it should be moving at.

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).

NORAD fails to notify the National Military Command Center (NMCC) at the Pentagon that aircraft have been hijacked before the NMCC initiates a significant event conference in response to the terrorist attacks. [9/11 Commission, 6/9/2004] NORAD’s Northeast Air Defense Sector (NEADS) was alerted to the first hijacking, of Flight 11, at 8:37 a.m. (see (8:37 a.m.) September 11, 2001) and it is alerted to the second hijacking, of Flight 175, at 9:03 a.m. (see (9:03 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20, 23] And yet, according to an after-action report produced by the NMCC, NORAD does not contact the NMCC to alert it to these incidents before the significant event conference commences, at 9:29 a.m. (see 9:29 a.m.-9:34 a.m. September 11, 2001). [9/11 Commission, 6/9/2004]
NORAD Does Not Provide Information to Deputy Director - Captain Charles Leidig, the acting deputy director for operations in the NMCC, will later say that he “does not remember getting a lot of information from NORAD” before the significant event conference begins. [9/11 Commission, 4/29/2004 pdf file] NMCC personnel apparently learn that an aircraft has been hijacked when an officer in the center calls the FAA at 9:00 a.m. (see 9:00 a.m. September 11, 2001). [9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 5/5/2004; 9/11 Commission, 7/24/2004, pp. 35]
NORAD First Mentions a Hijacking at 9:33 a.m. - NORAD will apparently talk to the NMCC about a hijacking for the first time at around 9:33 a.m., when its representative on the significant event conference states that they “concur that [a] hijacked aircraft is still airborne [and] heading towards Washington, DC.” [US Department of Defense, 9/11/2001; US Department of Defense, 9/11/2001 pdf file] (They will presumably be referring to the incorrect information that Flight 11 is still in the air after it has crashed into the World Trade Center (see 9:21 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 26] )
NORAD Does Not Request a Conference - Additionally, according to the NMCC’s after-action report, NORAD “does not request any conference at [National Command Authority] level” prior to the commencement of the significant event conference. [9/11 Commission, 6/9/2004] The significant event conference is actually initiated by Leidig. The NMCC has an important role to play in an emergency like the current crisis. Its job under these circumstances “is to gather the relevant parties and establish the chain of command between the National Command Authority—the president and the secretary of defense—and those who need to carry out their orders,” according to the 9/11 Commission Report. [9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 37] It is also “the focal point within [the] Department of Defense for providing assistance” when there is a hijacking in US airspace, according to a recent military instruction (see June 1, 2001).

Colin Scoggins, the military liaison at the FAA’s Boston Center, calls the FAA’s New York Center but is quickly cut off when the air traffic controller who answers says the center is busy dealing with a hijacking. According to author Lynn Spencer, Scoggins “calls New York Center to notify them that American 11 appears to be descending toward New York, most likely to land at JFK” International Airport. But the controller who takes the call snaps at him: “We’re too busy to talk. We’re working a hijack,” and then hangs up. According to Spencer, the New York Center controller is referring to Flight 175, but “Scoggins just figures that he’s talking about American 11. He has no idea that a second airliner is in crisis.” However, the timing of this call is unclear. If it is made while Flight 11 is descending toward New York, this would mean it occurs in the minutes before 8:46, when Flight 11 crashes (see 8:46 a.m. September 11, 2001). But in Spencer’s account, the call is made just after New York Center controller Dave Bottiglia notices that Flight 175’s transponder code has changed and he calls out to another controller, “I can’t get a hold of UAL 175 at all right now and I don’t know where he went to” (see 8:51 a.m.-8:53 a.m. September 11, 2001). [Spencer, 2008, pp. 48-49] The transcript of radio communications between the New York Center and Flight 175 shows that this would mean Scoggins’s call occurs around 8:53 a.m.-8:54 a.m., about seven minutes after Flight 11 crashes.

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

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.

After 9/11, NORAD and other sources will claim that NORAD’s Northeast Air Defense Sector (NEADS) is notified at this time that Flight 175 has been hijacked. [Washington Post, 9/12/2001; CNN, 9/17/2001; North American Aerospace Defense Command, 9/18/2001; Associated Press, 8/19/2002; Newsday, 9/10/2002] However, the FAA’s New York Center, which is handling Flight 175, first alerts its military liaison about the hijacking at around 9:01 (see 9:01 a.m.-9:02 a.m. September 11, 2001). In addition, according to the 9/11 Commission, NEADS is not informed until two minutes later (see (9:03 a.m.) September 11, 2001). [9/11 Commission, 6/17/2004] According to the Commission, the first “operational evidence” that there is something wrong on Flight 175 is not until 8:47, when its transponder code changes (see 8:46 a.m.-8:47 a.m. September 11, 2001), and it is not until 8:53 that the air traffic controller handling it concludes that Flight 175 may be hijacked (see 8:51 a.m.-8:53 a.m. September 11, 2001).

Flight 175 stops transmitting its transponder signal. It is currently flying near the New Jersey-Pennsylvania border. [Guardian, 10/17/2001; Newsday, 9/10/2002; 9/11 Commission, 6/17/2004] However, the transponder is turned off for only about 30 seconds, and then comes back on as a signal that is not designated for any plane on this day. Then, within the space of a minute, it is changed to another new code. But New York Center air traffic computers do not correlate either of these new transponder codes with Flight 175. Consequently, according to an early FAA report, “the secondary radar return (transponder) indicating aircraft speed, altitude, and flight information began to coast and was no longer associated with the primary radar return.” Therefore, while controllers are able “to track the intruder easily… they couldn’t identify it.” However, Dave Bottiglia, the New York Center air traffic controller responsible for Flight 175, is currently trying to locate the already-crashed Flight 11, and therefore supposedly does not notice the transponder code changes on Flight 175 until 8:51 a.m. (see 8:51 a.m.-8:53 a.m. September 11, 2001). [Federal Aviation Administration, 9/17/2001 pdf file; Washington Post, 9/17/2001; 9/11 Commission, 8/26/2004, pp. 21] According to a “Flight Path Study” by the National Transportation Safety Board, the change of Flight 175’s transponder code is the “first indication of deviation from normal routine.” [National Transportation Safety Board, 2/19/2002 pdf file]

[Source: NBC News]After being focused on Flight 11, Dave Bottiglia, an air traffic controller at the FAA’s New York Center, first notices problems with Flight 175. [MSNBC, 9/11/2002; 9/11 Commission, 7/24/2004, pp. 21] Both Flight 11 and Flight 175 have been in the airspace that Bottiglia is responsible for monitoring (see 8:40 a.m. September 11, 2001 and (8:42 a.m.-8:46 a.m.) September 11, 2001). Bottiglia has just watched Flight 11’s radar blip disappear, which means the plane has dipped below his radar’s coverage area, so is below 2,000 feet. But he does not yet realize it has crashed. He says aloud, “Well, we know he’s not high altitude anymore.” [MSNBC, 9/11/2002; Spencer, 2008, pp. 37] Around this time, Flight 175’s transponder changes twice in the space of a minute (see 8:46 a.m.-8:47 a.m. September 11, 2001).
Conflicting Accounts - According to MSNBC, “within seconds” of losing Flight 11’s blip, “Bottiglia has another unexpected problem.” While looking for Flight 11, he realizes that Flight 175 is also missing, and “instinctively… knows the two [planes] are somehow related.” He asks another controller to take over all of his other planes. [MSNBC, 9/11/2002] But according to the 9/11 Commission’s account, Bottiglia is still trying to locate Flight 11 after it crashes, and so it is not until 8:51 a.m. that he notices the problem with Flight 175 (see 8:51 a.m.-8:53 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 21]
'An Intruder over Allentown' - Around the time Flight 175 changes its transponder code, air traffic controller Curt Applegate, who is sitting at the radar bank next to Bottiglia’s, sees a blip that might be the missing Flight 11. He shouts out: “Look. There’s an intruder over Allentown.” According to the Washington Post, “In air traffic jargon, an ‘intruder’ is a plane with an operating transponder that has entered restricted airspace without permission.” In fact, it is the missing Flight 175. [Washington Post, 9/17/2001; MSNBC, 9/11/2002] However, these accounts make no mention of NORAD being notified about the problems with Flight 175 at this time. But according to a NORAD timeline released shortly after 9/11, NORAD’s Northeast Air Defense Sector (NEADS) was alerted about Flight 175 by the FAA several minutes earlier, at 8:43 a.m. (see 8:43 a.m. September 11, 2001).

CNN is the first major network to show the footage of the crash site. It breaks into a commercial and anchor Carol Lin says, “This just in. You are looking at… obviously a very disturbing live shot there—that is the World Trade Center, and we have unconfirmed reports this morning that a plane has crashed into one of the towers of the World Trade Center.” CNN then switches to Sean Murtagh, the network’s vice president of finance, who says in a live telephone interview, “I just witnessed a plane that appeared to be cruising at a slightly lower than normal altitude over New York City. And it appears to have crashed into—I don’t know which tower it is—but it hit directly in the middle of one of the World Trade Center towers. It was a jet, maybe a two-engine jet, maybe a 737… a large passenger commercial jet… It was teetering back and forth, wing-tip to wing-tip, and it looks like it has crashed into—probably, twenty stories from the top of the World Trade Center—maybe the eightieth to eighty-fifth floor. There is smoke billowing out of the World Trade Center.” [CNN, 9/11/2001; Bamford, 2004, pp. 16-17] Many reports do not come until a few minutes later.

[Source: Publicity photo]Apparently, managers at United Airlines’ System Operations Control (SOC) center, just outside Chicago, are unaware of any unfolding emergency until they see CNN reporting the burning World Trade Center (see 8:48 a.m. September 11, 2001). “Within minutes,” the air traffic control coordinator at United Airlines’ headquarters, located next to the SOC, calls an official at the FAA’s Herndon Command Center to confirm that the plane that just hit the WTC was not one of United’s aircraft. The FAA official tells him the plane had been a hijacked American Airlines 757. Soon afterwards, the air traffic control coordinator briefs Bill Roy and Mike Barber—the director and the dispatch manager at United’s SOC—on this information from the FAA. Barber then tries notifying United’s top corporate officials about it. However, he is unable to because the airline’s pager system is not working.

The United Airlines System Operations Control center.The United Airlines System Operations Control center. [Source: United Airlines]Andy Studdert, United Airlines’ chief operating officer, learns that an American Airlines plane has crashed into the World Trade Center and goes to his airline’s operations center to help respond to the incident, but when he gets there he is told that one of his airline’s planes, Flight 175, is missing. Studdert is in a meeting at United Airlines’ headquarters, near Chicago, with Jim Goodwin, the airline’s chairman and CEO; Rono Dutta, the airline’s president; and three or four other individuals. [Wall Street Journal, 10/15/2001; Chicago Tribune, 7/16/2003; 9/11 Commission, 11/20/2003 pdf file] The meeting, in Goodwin’s office, is about union negotiations. [Center for Values-Driven Leadership, 4/23/2012] Meanwhile, personnel in the airline’s System Operations Control (SOC) center have seen the television coverage of the burning North Tower and been informed that the WTC was hit by an American Airlines plane (see (Shortly After 8:48 a.m.) September 11, 2001). Bill Roy, the SOC director, called the adjacent headquarters building and passed on the news to Studdert’s secretary, Maryann Irving.
Managers Are Baffled at the News of the Crash - Irving now runs to Goodwin’s office and, once there, tells Studdert: “Andy, call the SOC. An American plane just went into the World Trade Center.” [Wall Street Journal, 10/15/2001; 9/11 Commission, 11/20/2003 pdf file] The men in the office, Studdert will later recall, say to each other: “That’s nuts. That can’t happen. There’s no way, under any circumstances, that an airline pilot is gonna hit the World Trade Center.” [Center for Values-Driven Leadership, 4/23/2012] Studdert thinks the plane that hit the WTC “couldn’t have been American Airlines, because that wasn’t an ordinary flight route.” [9/11 Commission, 11/20/2003 pdf file] The men in Goodwin’s office switch on a TV and see the coverage of the WTC on fire.
Manager Learns that a United Airlines Flight Is Missing - Studdert immediately goes to respond to the incident. Although the plane that reportedly hit the WTC doesn’t belong to United Airlines, according to Studdert, “there’s a fraternity… of the airlines, so we would help each other during a crisis.” He heads across the complex to the SOC—the operations center. [Center for Values-Driven Leadership, 4/23/2012] The operations center is a room about the size of a football field in which around 300 people are working, tracking planes and pulling up information relating to the airline’s flights. [Longman, 2002, pp. 77] When Studdert arrives there, he says aloud, “Confirm American into the World Trade Center.” [Chicago Tribune, 7/16/2003; Center for Values-Driven Leadership, 4/23/2012] However, someone in the operations center informs him that contact has now been lost with a United Airlines plane, Flight 175. A few minutes later, Studdert is told that a supervisor at the airline’s maintenance office in San Francisco called and said Flight 175 has been reported as hijacked (see Shortly Before 9:00 a.m. September 11, 2001). [Wall Street Journal, 10/15/2001; Chicago Tribune, 7/16/2003; 9/11 Commission, 11/20/2003 pdf file; 9/11 Commission, 8/26/2004, pp. 22]
Manager Tells Employees, 'This Is Not a Drill' - Studdert is concerned that personnel in the operations center might think the apparent crisis is a scenario in a training exercise. [Chicago Tribune, 7/16/2003] This is because 12 days ago he held a surprise exercise in which contact was lost with a United Airlines plane flying over the Pacific Ocean and airline personnel were led to believe the aircraft had crashed (see August 30, 2001). [USA Today, 8/12/2002; Studdert, 5/26/2015 pdf file; Dubuque Telegraph Herald, 11/12/2015] It is possible that personnel in the operations center are indeed confused over whether the current crisis is simulated, as part of another exercise. According to the Chicago Tribune, Studdert senses “disbelief among his employees” and so he tells them, “This is not a drill.” [Chicago Tribune, 7/16/2003] But according to USA Today, “the staff already knows” this is not another exercise. [USA Today, 8/12/2002]
Airline Employees See Second Crash on TV - At 9:03 a.m., Studdert and his colleagues see Flight 175 crashing into the South Tower of the WTC live on television (see 9:03 a.m. September 11, 2001). [Wall Street Journal, 10/15/2001] Studdert, however, is unsure whether this second plane to hit the WTC was a United Airlines flight, because the clarity of the image on television is too poor to tell. [9/11 Commission, 11/20/2003 pdf file] Studdert will be involved in activating his airline’s crisis center in response to the attacks (see (9:00 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.

Alarmed because his younger brother works at the WTC, he calls him immediately. Adam Arias works for an investment company on the 84th floor of the South Tower. According to some accounts, Don Arias tells his brother that the aircraft that crashed into the North Tower was likely a hijacked plane that he has been informed of, and orders him to “Get out of there. Go home.” [Florida State Times, 11/2001; Newhouse News Service, 1/25/2002; Airman, 9/2002] But according to Newsday, Don Arias tells his brother he has heard there is “another hijacked airliner and might be another attack.” [Newsday, 10/30/2001] This would be consistent with an early NORAD timeline, which had the agency receiving notification of the second hijacking at 8:43 a.m. (see 8:43 a.m. September 11, 2001). However, later accounts, including the 9/11 Commission Report, will claim NORAD only hears of it around the time the plane hits the South Tower (see (9:03 a.m.) September 11, 2001).

Flight 77’s transponder is turned off, meaning that the aircraft’s speed, altitude, and flight information are no longer visible on radar displays at the FAA’s Indianapolis Center. [Federal Aviation Administration, 9/17/2001 pdf file; National Transportation Safety Board, 2/19/2002 pdf file; 9/11 Commission, 7/24/2004, pp. 9] The Indianapolis Center air traffic controller in charge of Flight 77 watched the plane go off course and head southwest before its data disappeared from his radar screen. He looks for primary radar signals along the aircraft’s projected flight path as well as in the airspace where it had started to turn, but cannot find it. [9/11 Commission, 6/17/2004] He tries contacting the plane repeatedly, saying “American 77, Indy,” and: “American 77, Indy, radio check. How do you read?” But there is no response. [New York Times, 10/16/2001; New York Times, 10/16/2001]
NEADS Not Contacted - US News and World Report will later comment, “[E]xperts say that an airliner making a 180-degree turn followed by a transponder turnoff should have been a red flag to controllers.” It will quote Robert Cauble, a 20-year veteran of Navy air traffic control, who says: “The fact that the transponder went off, they should have picked up on that immediately. Everyone should have been on alert about what was going on.” [US News and World Report, 10/8/2001] Yet the Indianapolis Center supposedly does not notify NORAD’s Northeast Air Defense Sector (NEADS). According to the 9/11 Commission, NEADS will only learn that Flight 77 is missing at 9:34 a.m. (see 9:34 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 26-27]

He mistakenly assumes Flight 77 has experienced an electrical or mechanical failure. [Guardian, 10/17/2001; 9/11 Commission, 6/17/2004] After he informs other Indianapolis Center personnel of the developing situation, they will clear all other aircraft from the plane’s westerly route so their safety will not be affected if Flight 77 is still flying along its original path but unable to be heard.

Now ten.” [Newsday, 9/10/2002; Vanity Fair, 8/1/2006] Dave Bottiglia, the controller responsible for monitoring Flight 175, will later comment that 10,000 feet per minute is “absolutely unheard of for a commercial jet. It is unbelievable for the passengers in the back to withstand that type of force as they’re descending. [The hijackers are] actually nosing the airplane down and doing what I would call a ‘power dive.’” [The Learning Channel, 8/20/2006] While Flight 175 is in this rapid descent, it heads directly into the paths of several other aircraft, and narrowly avoids a mid-air collision with flight Midex 7 (see (9:01 a.m.) September 11, 2001).

Jim Goodwin.Jim Goodwin. [Source: Chicago Tribune]Rich Miles, the manager at the United Airlines System Operations Control (SOC) center just outside Chicago, receives a call from a supervisor at United’s maintenance office in San Francisco, informing him that Flight 175 has been reported as hijacked. [Wall Street Journal, 10/15/2001; 9/11 Commission, 8/26/2004, pp. 22] The maintenance office received a call minutes earlier from a flight attendant on United 175, who said their plane had been hijacked (see 8:52 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 7-8] When the supervisor tells Miles about this, he initially responds, “No, the information we’re getting is that it was an American 757.” (The FAA has just informed United Airlines that the plane that hit the World Trade Center was a hijacked American Airlines 757 (see (Shortly After 8:48 a.m.) September 11, 2001).) But the supervisor insists, “No, we got a call from a flight attendant on 175.” [Wall Street Journal, 10/15/2001] Miles notifies his boss Bill Roy, the SOC director, about this information. Roy then contacts United’s CEO Jim Goodwin and its chief operating officer Andy Studdert, who are in a meeting at the airline’s headquarters, located next to the SOC. Roy then begins the process of activating the crisis center at the United headquarters, which will take about 30 minutes to complete.

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).

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

Moments before Flight 175 crashes into the World Trade Center, Colin Scoggins, the military liaison at the FAA’s Boston Center, calls NORAD’s Northeast Air Defense Sector (NEADS) to notify it that there is a second hijacked aircraft over the US. Scoggins learned of the second hijacking on the FAA headquarters’ hijack teleconference (see (Shortly Before 9:02 a.m.) September 11, 2001) and senses that he should call NEADS with this latest information. According to author Lynn Spencer, Scoggins “imagines that he must be one of dozens of FAA facilities flooding [NEADS] with phone calls. What he doesn’t know is that his is in fact the only one giving them information about the flights this morning, other than the coverage on CNN.” [Spencer, 2008, pp. 82] However, the 9/11 Commission will say that NEADS also learns of the second hijacking around this time from the FAA’s New York Center, stating, “The first indication that the NORAD air defenders had of the second hijacked aircraft, United 175, came in a phone call from New York Center to NEADS at 9:03” (see (9:03 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 23] Just after Scoggins reports the second hijacking to NEADS, those on the NEADS operations floor see the live television coverage of Flight 175 hitting the South Tower on a screen at the front of the room. [Spencer, 2008, pp. 82] Apparently, Scoggins’s phone call continues for several minutes: According to the 9/11 Commission, “Between 9:04 a.m. and 9:07 a.m., the NEADS identification technicians were on the phone with FAA Boston Center seeking further information on Flight 175 when Boston Center confirmed a second crash at the World Trade Center.” [9/11 Commission, 8/26/2004, pp. 24]

The 9/11 Commission will later conclude that the FAA’s New York Center tells NORAD’s Northeast Air Defense Sector (NEADS) that Flight 175 has been hijacked at this time. The Commission will refer to this as “the first indication that the NORAD air defenders had of the second hijacked aircraft.” The notification is apparently received from the military liaison at the New York Center (see 9:01 a.m.-9:02 a.m. September 11, 2001). [9/11 Commission, 6/17/2004]
NEADS Technician Announces 'Second Possible Hijack' - Tape recordings of the NEADS operations floor will reveal ID tech Stacia Rountree answering the call from the New York Center, and saying out loud, “They have a second possible hijack!” [Vanity Fair, 8/1/2006] Colonel Robert Marr, the NEADS battle commander, will claim he first learns that an aircraft other than Flight 11 has been hijacked when he sees Flight 175 crash into the World Trade Center on television. [Aviation Week and Space Technology, 6/3/2002] Lieutenant Colonel Dawne Deskins will claim that when she sees Flight 175 hitting the South Tower on television, “we didn’t even know there was a second hijack.” [Filson, 2003, pp. 59]
Conflicting Accounts - However, these accounts contradict NORAD’s claim that it makes shortly after 9/11 that NEADS was first notified about Flight 175 at 8:43 a.m. (see 8:43 a.m. September 11, 2001). [North American Aerospace Defense Command, 9/18/2001] Additionally, as Flight 175 crashes into the WTC, Canadian Captain Mike Jellinek, who is working at NORAD’s Cheyenne Mountain, Colorado operations center, is on the phone with NEADS. He sees the crash live on television and asks NEADS, “Was that the hijacked aircraft you were dealing with?” The reply is yes. (However, it is unclear whether Jellinek is referring to Flight 175 or to the smoke coming from the crash of Flight 11.) [Toronto Star, 12/9/2001] If the 9/11 Commission’s account is correct, several questions remain unanswered. Flight 175 lost radio contact at 8:42 a.m. (see 8:41 a.m.-8:42 a.m. September 11, 2001) and changed transponder signals at 8:47 a.m. (see 8:46 a.m.-8:47 a.m. September 11, 2001); an air traffic controller declared it possibly hijacked sometime between 8:46 a.m. and 8:53 a.m. (see (Shortly After 8:46 a.m.) September 11, 2001); and an air traffic control manager called it hijacked at 8:55 a.m.(see (8:55 a.m.) September 11, 2001). The Commission will not explain why the New York Center waits 10 to 16 minutes before warning NEADS that Flight 175 is possibly hijacked. [9/11 Commission, 6/17/2004]

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]

Within minutes of the second World Trade Center tower being hit, United Airlines tells the FAA’s Boston Center that Flight 175 is down. This is according to Colin Scoggins, a civilian manager who is the military liaison at the Boston Center. Scoggins will later recall, “When we phoned United [after the second tower was hit], they confirmed that United 175 was down, and I think they confirmed that within two or three minutes.” [Vanity Fair, 8/1/2006] However, according to the 9/11 Commission, even though by 9:20 United Airlines suspects that the second plane to hit the WTC was Flight 175 (see Between 9:10 a.m. and 9:20 a.m. September 11, 2001), at that time the identity of the crashed aircraft is “still unconfirmed.” It is not until 9:22 that United issues an advisory to its facilities, stating that Flight 175 has been in an accident in New York (see 9:22 a.m. September 11, 2001).

After conferring with the FAA’s New England regional office and contacting representatives of the Air Transport Association, the FAA’s Boston Center decides to issue a Notice to Airmen, warning pilots to heighten cockpit security. [9/11 Commission, 8/26/2004, pp. 24-25] Following the second attack on the World Trade Center, Terry Biggio, the operations manager at the Boston Center, is concerned that there may be additional attacks. He therefore asks a manager at the FAA’s New England regional office if warnings could be sent to airborne aircraft via “ACARS or something,” advising them to increase their cockpit security. [9/11 Commission, 8/26/2004, pp. 24] (ACARS is an e-mail system that allows personnel on the ground to rapidly communicate with those in the cockpit of an aircraft. [9/11 Commission, 8/26/2004, pp. 9] ) Biggio is particularly concerned about the need to warn airborne international flights that are scheduled to arrive at New York’s JFK International Airport. On the advice of a New England Region representative, Boston Center decides to contact Air Transport Association representatives through the FAA’s Herndon Command Center and ask them to formally request that airlines warn their aircraft to heighten cockpit security. According to the 9/11 Commission, though, Biggio is “[n]ot content to rely on the airlines to warn their aircraft,” and so decides that the Boston Center will issue a Notice to Airmen (“NOTAM”) to heighten cockpit security in light of the attacks in New York. [9/11 Commission, 8/26/2004, pp. 24-25] The NOTAM system is the communication method used to define the rules of the day for air traffic controllers and pilots. With the status of equipment, airports, and rules changing frequently, the NOTAM system is used to distribute any changes to all pilots and controllers. [Freni, 2003, pp. 86] Two or three minutes later, controllers at the Boston Center will contact all the aircraft in their airspace by radio and advise them to increase cockpit security (see 9:09 a.m.-9:10 a.m. September 11, 2001).

Terry Biggio, the operations manager at the FAA’s Boston Center, instructs the air traffic controllers at his center to contact all aircraft in the center’s airspace by radio and inform them of the events taking place in New York. He tells the controllers to also advise the aircraft to heighten their cockpit security in light of these events. [9/11 Commission, 7/24/2004, pp. 23; 9/11 Commission, 8/26/2004, pp. 25] According to author Lynn Spencer, previously “No transmission of that kind has ever been made on air traffic control frequencies.” Controller Jim Ekins is the first to act. He announces over all the radio frequencies in the sector: “All aircraft! Due to recent events that have unfolded in the Boston sector, you are advised to increase cockpit security. Allow no entry to your cockpit!” According to Spencer, other controllers nearby overhear and realize: “Yes! That’s exactly what we need to tell them!” [Spencer, 2008, pp. 98] The Boston Center air traffic controllers then immediately execute Biggio’s order, and give the warning to their aircraft. [9/11 Commission, 8/26/2004, pp. 25] However, Spencer will write: “Communications with controllers are [usually] as dry as they come, and to many pilots this announcement is so out of their realm of understanding, training, and experience that it simply doesn’t make sense. It actually agitates some, who cannot help but view it as some new kind of ‘FAA bureaucratic bullsh_t.’” [Spencer, 2008, pp. 99] Boston Center will subsequently ask the FAA’s Herndon Command Center to issue a similar cockpit security alert nationwide, but the Command Center apparently will not act on this request (see (9:15 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 23] United Airlines will issue a company-wide order at 9:21 for its dispatchers to warn their flights to secure their cockpits (see 9:21 a.m. September 11, 2001).

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.

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]

Shortly after he learns a second plane has hit the World Trade Center, United Airlines flight dispatcher Ed Ballinger takes the initiative to begin sending a warning message to the flights he is monitoring, including Flight 93 and Flight 175 (although this aircraft has already crashed). [9/11 Commission, 7/24/2004, pp. 11; 9/11 Commission, 8/26/2004, pp. 26 and 37] Ballinger is responsible for monitoring United’s aircraft flying from the East Coast to the West Coast. He has 16 such flights he is in charge of. [Chicago Daily Herald, 4/14/2004] He sends out a text message to his airborne flights: “Beware any cockpit intrusion… Two aircraft in NY hit [World] Trade Center builds.” [9/11 Commission, 7/24/2004, pp. 11; 9/11 Commission, 8/26/2004, pp. 26] Although United Airlines has suspected Flight 175 as being hijacked since around 9:00 a.m. (see Shortly Before 9:00 a.m. September 11, 2001), Ballinger is still responsible for multiple flights. (In contrast to United, American Airlines has a policy that flight dispatchers should only manage the hijacked flight, and be relieved of responsibility for their other flights.) [9/11 Commission, 7/24/2004, pp. 455-456] Ballinger’s warning is therefore sent out to his aircraft in groups, and will not be sent to Flight 93 until 9:23 a.m. (see 9:23 a.m.-9:26 a.m. September 11, 2001). Unaware that it was the second plane that hit the WTC, Ballinger will also send the message to Flight 175 (see 9:23 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 26 and 37] Ballinger begins sending out these warnings two minutes before United Airlines instructs its dispatchers to warn their flights to secure their cockpit doors (see 9:21 a.m. September 11, 2001). [9/11 Commission, 1/27/2004; 9/11 Commission, 7/24/2004, pp. 455] According to the 9/11 Commission, his text message represents “the first occasion on 9/11 when either American or United sent out such a warning to their airborne aircraft.” [9/11 Commission, 8/26/2004, pp. 37] Ballinger will later recall: “As soon as I had a grasp of what was going on… I sent [the warning] out immediately. It was before [Transportation Secretary Norman] Mineta, and even before the airlines told us to alert the crews.” [Chicago Daily Herald, 4/14/2004]

United Airlines Flight 23, a Boeing 767 bound from JFK International Airport in New York to Los Angeles, cancels its takeoff and may thus avoid becoming the morning’s fifth hijacked plane. It was scheduled to depart at 8:30 a.m., but was late in pushing back from the gate and is still waiting in line to take off. [Associated Press, 9/13/2001; New York Times, 10/20/2001] The plane’s pilots, Tom Mannello and Carol Timmons, have heard a report over their radio that a plane has flown into the World Trade Center. They then receive a text message from United Airlines dispatcher Ed Ballinger, which reportedly states: “We have gone to heightened security. Do not open cockpit doors. Secure the cockpit.” [Spencer, 2008, pp. 102-103] This is presumably the message Ballinger sent out at 9:19 (see 9:19 a.m. September 11, 2001), though it seems to be more like a description of the message he sends out at 9:32 (see 9:32 a.m.-9:33 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 37 and 39]
Pilots Alarmed at Warning - Having never received a warning like this before, the pilots are alarmed. Timmons starts barricading the cockpit door with their suitcases while Mannello grabs the crash ax for protection. Mannello calls the plane’s lead flight attendant to inform her of the threat, and tells her not to open the cockpit door under any circumstances. Soon afterwards, she calls back and informs him: “We [the plane’s flight attendants] just think you should know this because we think it is unusual. We have four young Arab men sitting in first class this morning.” [Spencer, 2008, pp. 103] (Other accounts will claim there are three or even six suspicious passengers on the flight. [Associated Press, 9/13/2001; Chicago Daily Herald, 4/14/2004] ) Mannello hasn’t been told what the reported threat is about or if it relates to Arabs, so simply thanks the attendant for the information. Minutes later, the pilots receive a radio message from ground control, announcing, “All aircraft, be advised that the airport is now closed.” A subsequent message announces the airport is being evacuated. Mannello decides to move his aircraft back to the terminal. [Spencer, 2008, pp. 103-104]
Arab Passengers Become Aggressive - After the passengers are told their flight has been canceled, the Arab men become upset. They stand up and start urgently consulting with each other, and then refuse to return to their seats. [Associated Press, 9/13/2001; New York Times, 10/20/2001] One official will later describe: “These guys got belligerent, and said something like, ‘We’ve got to be on this plane.’ They expressed a desire to remain on the plane and resisted getting off.” [New York Times, 9/14/2001] According to the Associated Press, “The argument with a member of the flight crew became so heated that the crew member called airport security. But before security arrived, the men had vanished.” [Associated Press, 9/13/2001]
Evidence Indicates Plans for Hijacking Plane - Authorities will later check the men’s unclaimed baggage and find box-cutters, copies of the Koran, and al-Qaeda instruction sheets. [Chicago Daily Herald, 4/14/2004; Spencer, 2008, pp. 105] In 2002, apparently referring to this incident, Lieutenant General Ken Pennie, the deputy commander of NORAD, will state, “We suspect there might have been more than just the four aircraft involved” as targets for the 9/11 attacks. [Globe and Mail, 6/13/2002] The FBI will investigate this incident and go through the flight manifest to determine the names of the Arab men, who are believed to have had ticketed reservations. [Associated Press, 9/13/2001; New York Times, 9/14/2001] Investigators will interview the plane’s crew nearly half a dozen times. But no information about the suspicious Arab passengers is ever released to the public. [Spencer, 2008, pp. 105] On September 14, it is reported that investigators believe at least one of these passengers was among a number of individuals taken into custody at JFK and La Guardia Airports the previous day (see September 13-14, 2001). [New York Times, 9/14/2001] However, these detained individuals are soon cleared of any connection with the events of 9/11 and are released. [Associated Press, 9/14/2001] In 2004, Representative Mark Kirk (R-IL) will say the suspicious Flight 23 passengers were never found and are likely still at large. [Chicago Daily Herald, 4/14/2004]

United Airlines issues a companywide order for its flight dispatchers to warn their flights to secure their cockpit doors. [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].

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]

The FAA’s Cleveland Center.The FAA’s Cleveland Center. [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).

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

[Source: Federation of American Scientists]A technician at NORAD’s Northeast Air Defense Sector (NEADS) instructs personnel on the NEADS operations floor to turn off their “sim switches,” apparently so as to remove from their radar screens simulated information for a training exercise that was being conducted this morning. [Northeast Air Defense Sector, 8/23/2001; North American Aerospace Defense Command, 9/11/2001; 9/11 Commission, 2004]
Staffer Complained, 'Let's Get Rid of This Goddamn Sim' - A few minutes earlier, at 9:30 a.m., a member of staff on the operations floor complained about simulated information—presumably false tracks—appearing on NEADS radar screens. He said: “You know what, let’s get rid of this godd_mn sim. Turn your sim switches off. Let’s get rid of that crap.” [North American Aerospace Defense Command, 9/11/2001; North American Aerospace Defense Command, 9/11/2001] (A “sim switch” presumably allows simulated material on radar scopes to be turned on or off.)
Technician Instructs, 'Turn Off Your Sim Switches' - Now a member of NEADS staff, who according to a 9/11 Commission document is Technical Sergeant Jeffrey Richmond, gives an instruction to the NEADS surveillance technicians, “All surveillance, turn off your sim switches.” Seconds later, apparently in response to this instruction, someone on the operations floor tells a colleague, “You got your sim switches down.” [North American Aerospace Defense Command, 9/11/2001; 9/11 Commission, 2004]
Sim Switches Turned On for Day's Exercise - Simulated material (“sim”) is apparently appearing on NEADS radar screens because of the NORAD training exercise, Vigilant Guardian, that was being conducted this morning (see (6:30 a.m.) September 11, 2001). Former Deputy Secretary of Defense John Hamre has revealed that NORAD has the capacity to inject simulated material into the system, “as though it was being sensed for the first time by a radar site.” In a training exercise in December 1998, for example, NORAD ran “30 different simulations, some of them being mass attacks, some of them being single missiles.” An information page on the current exercise stated, “All of NEADS, operations personnel are to have their sim switches turned ‘on’ starting at 1400Z 6 Sept. 01 till endex [the end date of the exercise].” Since Vigilant Guardian was originally scheduled to continue until September 13, this would mean NEADS personnel had their sim switches turned on this morning. [US Department of Defense, 1/15/1999; Northeast Air Defense Sector, 8/23/2001]
Radar Equipment Set to Display 'Sim Tracks' - A memo outlining special instructions for Vigilant Guardian participants further detailed how NORAD equipment needed to be set to display simulated material during the exercise. It stated: “The exercise will be conducted sim over live on the air sovereignty string. The Q-93 must be placed in the mixed mode to allow the telling [i.e. the communicating of information between facilities] of sim tracks.” [Northeast Air Defense Sector, 8/23/2001] The Q-93 is a piece of equipment used by NORAD, which is described as “a suite of computers and peripheral equipment configured to receive plot data from ground radar systems,” and which “performs track processing.” [General Accounting Office, 12/24/1992 pdf file; Federation of American Scientists, 4/23/2000] The Q-93 also “receives flight plans from the FAA, and has bi-directional communications with NORAD headquarters and a real-time link to AWACS [Airborne Warning and Control System planes].” [Satterthwaite, Corman, and Herm, 6/2002]
Exercise Supposedly Canceled Earlier On - While NEADS radar scopes are still displaying simulated material as late as 9:34 a.m., some accounts will claim the Vigilant Guardian 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 according to a report in the Toronto Star, “Any simulated information” for the exercise was “purged from the [radar] screens” at NORAD’s operations center in Cheyenne Mountain, Colorado, shortly before the second WTC tower was hit (see (9:00 a.m.) September 11, 2001). [Toronto Star, 12/9/2001] However, NEADS will receive a phone call from the operations center at 10:12 a.m. in which the caller asks it to “terminate all exercise inputs coming into Cheyenne Mountain” (see 10:12 a.m. September 11, 2001).

Personnel at NORAD’s Northeast Air Defense Sector (NEADS) are following Flight 93 while it is still flying west and before it reverses course, according to the accounts of some NEADS and NORAD officials, but their claims will be disputed by the 9/11 Commission. [Filson, 2003, pp. 68, 71; 9/11 Commission, 10/30/2003 pdf file; 9/11 Commission, 8/26/2004, pp. 100-101]
NEADS Watches Flight 93 Heading West - Colonel Robert Marr, the battle commander at NEADS, will later recall that around this time, “his focus” is on Flight 93, which, he will say, is “circling over Chicago.” [9/11 Commission, 10/27/2003 pdf file] Marr will tell author Leslie Filson that the flight is being monitored by NEADS personnel while it is still flying west. He will describe: “We don’t have fighters that way and we think [Flight 93 is] headed toward Detroit or Chicago. I’m thinking Chicago is the target.” Marr will say NEADS contacts an Air National Guard base in the area, “so they [can] head off 93 at the pass” (see (9:55 a.m.) September 11, 2001). [Filson, 2003, pp. 68]
NORAD Watching Flight 93 When It Changes Course - Lieutenant Colonel Mark Stuart, an intelligence officer who is in the NEADS battle cab with Marr, will give a similar account. He will say that when the Flight 93 “incident began to unfold,” it was his “professional judgment that the plane was going to strike the Sears Tower in Chicago, and he passed that judgment to Colonel Marr.” [9/11 Commission, 10/30/2003 pdf file] And Major General Larry Arnold, the commander of the Continental United States NORAD Region, will say that NORAD personnel are already following Flight 93 at 9:36 a.m., when it reverses course and heads back east (see (9:36 a.m.) September 11, 2001). He will tell Filson, “[W]e watched the 93 track as it meandered around the Ohio-Pennsylvania area and started to turn south toward [Washington,] DC.” [National Transportation Safety Board, 2/19/2002 pdf file; Filson, 2003, pp. 71; 9/11 Commission, 8/26/2004, pp. 41] Marr will similarly say “that he distinctly remembers watching [Flight 93] come west and turn over Cleveland.” [9/11 Commission, 1/23/2004 pdf file]
9/11 Commission Says No One at NORAD Watches Flight 93 - However, the 9/11 Commission will dispute these accounts. It will state: “The record demonstrates… that no one at any level in NORAD… ever ‘watched the 93 track’ start to turn south towards Washington, DC. In fact, the military never saw Flight 93 at all.” [9/11 Commission, 8/26/2004, pp. 101] NEADS will first be alerted to Flight 93 significantly later, at 10:07 a.m., according to the 9/11 Commission (see 10:05 a.m.-10:08 a.m. September 11, 2001).
Officer May Have Confused Flight 93 with Delta 1989 - The 9/11 Commission will suggest to Marr that he was mistaking Flight 93 for Delta Air Lines Flight 1989, an aircraft that is incorrectly reported as having been hijacked around this time (see (9:28 a.m.-9:33 a.m.) September 11, 2001 and 9:39 a.m. September 11, 2001). Marr will respond that he may have confused Flight 93 with Delta 1989, but say that “he believes the last point at which he saw Flight 93 was when it was over Ohio, before it turned off its transponder,” which happens at 9:41 a.m. (see (9:40 a.m.) September 11, 2001). [9/11 Commission, 1/23/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 27-30] Senior officials, including Marr and Arnold, will claim that the US military continues following Flight 93 after it reverses course and is heading toward Washington (see (9:36 a.m.-10:06 a.m.) September 11, 2001). [Filson, 2003, pp. 71, 73] Stuart will say that after Flight 93 changes course, he “and other NEADS people knew it was headed to DC.” [9/11 Commission, 10/30/2003 pdf file]

Having followed a seemingly normal course until now, after reaching the Cleveland area, Flight 93 suddenly makes a sharp turn to the south. It then makes another turn back eastward, cutting through West Virginia’s Northern Panhandle before re-entering Pennsylvania. [Washington Post, 9/12/2001; Pittsburgh Post-Gazette, 9/13/2001; 9/11 Commission, 8/26/2004, pp. 41] Having thus turned 180 degrees, it now heads toward Washington, DC. [CNN, 9/13/2001]

The Pentagon explodes. 
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]

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

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

[CNN, 9/17/2001; MSNBC, 9/3/2002; MSNBC, 9/11/2002; 9/11 Commission, 6/17/2004] However, the plane can be—and is—tracked using primary radar by Cleveland flight controllers and at United headquarters.

From 9:42 a.m., one of the Command Center managers (exactly who is unstated) gives the headquarters several updates on Flight 93’s progress and location. At 9:46 a.m., White tells Jeff Griffith, the FAA’s deputy director of air traffic, that Flight 93 is “29 minutes out of Washington, DC, and tracking toward us.” Two minutes later, in another conversation with Griffith, White confirms that Flight 93 has reversed course and is heading toward Washington.

[9/11 Commission, 1/22/2004 pdf file] NEADS has been contacted by the FAA’s Boston Center and incorrectly told that Delta 1989 is a possible hijacking (see 9:39 a.m. September 11, 2001). The aircraft is just south of Toledo, Ohio, and Colonel Robert Marr and Major Kevin Nasypany order the troops at NEADS to call Air National Guard bases in that area to see if any of them can launch fighters.

The air traffic control tower at Pittsburgh International Airport is evacuated, because of concerns that Flight 93, which is heading in the direction of the airport, could crash into it.

Cleveland Center Notifies Pittsburgh Tower - At 9:44 a.m., an air traffic controller at the FAA’s Cleveland Center calls the Pittsburgh Airport control tower and notifies it of the loss of radio contact with Flight 93, and the loss of a secondary radar return from that aircraft (see (9:40 a.m.) September 11, 2001). The Cleveland Center controller also says Flight 93 has made an unanticipated turn (see (9:36 a.m.) September 11, 2001), and its flight path will take it close to Pittsburgh Airport, if not directly over it. [Federal Aviation Administration, 3/21/2002, pp. 11-12 pdf file] The controller at the Pittsburgh tower who answers the call, apparently Paul Delfine, begins tracking Flight 93’s primary target on radar, and calls over his operations supervisor, Mal Fuller. [Federal Aviation Administration, 9/17/2001 pdf file; Lancaster New Era, 11/3/2006]
Supervisor Orders Evacuation - Delfine points to a plane—which Fuller only later learns is Flight 93—on a radar scope. He tells Fuller it was hijacked over Cleveland, and controllers don’t know where it is heading. Fuller will later recall: “In two sweeps of the radar, I could tell it was going very fast. It was headed directly for the control tower.” Fuller is aware of the attacks on the World Trade Center and the Pentagon, and, at 9:49, gives the order, “Evacuate the facility.” [Pittsburgh Post-Gazette, 9/23/2001; Lancaster New Era, 11/3/2006] By 9:51, the facility has been evacuated. [Federal Aviation Administration, 9/17/2001 pdf file] However, one controller refuses to leave his post and remains in the tower. [Spencer, 2008, pp. 193-194]
Employees Do Not See Flight 93 Overhead - Some of the evacuated employees are so upset that they immediately head home. Others mill around in a parking lot. Fuller will later guess that Flight 93 passed directly overhead as he was heading outside, but he assumes it was too high for anyone to see it. He will recall: “We watched and watched and watched. We never saw anything.” [Lancaster New Era, 11/3/2006]
Controllers Return to Facility - Minutes after evacuating, at 9:56 a small number of tower controllers will volunteer to return to their facility. Once back inside, they find that Flight 93’s track is no longer visible on their radar screens. At 10:05 a.m., tower personnel will contact the FAA’s Herndon Command Center to explain why they evacuated. They say they did so because there had been an aircraft, thought to be Flight 93, which appeared to be on a collision course with the tower, and this aircraft allegedly had a bomb on board. [Federal Aviation Administration, 9/17/2001 pdf file; Federal Aviation Administration, 3/21/2002, pp. 12-13 pdf file] Around the time the Pittsburgh Airport control tower evacuates, while Flight 93 is heading east, NEADS battle commander Colonel Robert Marr hears that the FAA’s Cleveland Center is being evacuated (see (10:17 a.m.) September 11, 2001).

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.

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).

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).

Leo Mullin.Leo Mullin. [Source: Publicity photo]Leo Mullin, the CEO of Delta Air Lines, calls FAA Administrator Jane Garvey at FAA headquarters in Washington, DC, and reports that four Delta aircraft are missing. Mullin, who is at his company’s headquarters in Atlanta, Georgia, tells Garvey: “We can’t find four of our planes. Four of our transponders are off.” [USA Today, 8/13/2002; Spencer, 2008, pp. 186] The identities of these aircraft are unstated. Whether they include Delta Flight 1989, which FAA air traffic controllers have mistakenly reported as being a possible hijacking (see (9:28 a.m.-9:33 a.m.) September 11, 2001 and 9:39 a.m. September 11, 2001), is unclear. At 9:27 a.m., the FAA’s Boston Center reported that this plane was missing (see 9:27 a.m. September 11, 2001). [North American Aerospace Defense Command, 9/11/2001; 9/11 Commission, 5/23/2003] But, according to the 9/11 Commission, Delta 1989 “never turned off its transponder.” [9/11 Commission, 7/24/2004, pp. 28] USA Today will report that, after “early reports that a bomb, then hijackers, might be aboard, Delta CEO Leo Mullin, 58, had nervously tracked [Delta 1989] from the company’s headquarters in Atlanta. Every five minutes, a new report came in. None seemed clear.” [USA Today, 8/13/2002]

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). [Federal Aviation Administration, 9/11/2001] According to Major Allan Knox, who works at the Air Force Rescue Coordination Center at Langley Air Force Base in Virginia, most ELT signals are false alarms.

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

Douglas Champagne.Douglas Champagne. [Source: David Kujawa / US Air Force]Although NORAD’s Northeast Air Defense Sector (NEADS) has contacted Selfridge Air National Guard Base in Michigan, reportedly to arrange that two of its F-16s be diverted from a training mission to intercept either Flight 93 or Delta Air Lines Flight 1989 (accounts conflict over which aircraft is concerned), the pilots of those jets apparently never receive an order to intercept a plane, and so return directly to their base. [Filson, 2003, pp. 68, 71; Wolverine Guard, 9/2006 pdf file; Mount Clemens-Clinton-Harrison Journal, 9/6/2006; Spencer, 2008, pp. 178] However, some accounts will claim the pilots are indeed ordered to intercept the suspect aircraft. [ABC News, 8/30/2002; Associated Press, 8/30/2002; Post-Standard (Syracuse), 3/27/2005; Spencer, 2008, pp. 188]
Jets Returning from Training Mission - The F-16s, piloted by Lieutenant Colonel Tom Froling and Major Douglas Champagne of the 127th Wing, had taken off from Selfridge Air National Guard Base at around 8:50 a.m. for a routine training mission at Grayling Range in central northern Michigan. The two pilots were oblivious to the attacks taking place in New York and Washington. [Filson, 2003, pp. 68; GlobalSecurity (.org), 4/26/2005; Wolverine Guard, 9/2006 pdf file] When they started heading back to Selfridge after completing their training mission, they began hearing “unusual radio traffic” as air traffic controllers began diverting flights from their original destinations. [Mount Clemens-Clinton-Harrison Journal, 9/6/2006]
Pilots Learn of Plane Hitting Pentagon - Froling will later recall: “Something strange was occurring and I couldn’t put my finger on what was happening. I could hear [the FAA’s] Cleveland Center talking to the airlines and I started putting things together and knew something was up.” [Filson, 2003, pp. 68-70] Champagne hears an air traffic controller stating that a plane has crashed at the Pentagon. He then hears the Cleveland Center announcing a “demon watch,” which means pilots have to contact their operations center for more information.
Commander Asks if Pilots Have Used up Their Ammunition - When Champagne calls the Selfridge base, his operations group commander, General Michael Peplinski, wants to know if he and Froling have used up their ammunition during the training mission. Champagne will recall: “[Peplinski] asked if we had expended all our munitions and specifically asked if we had strafed. We replied that all ordnance was gone. I assumed we had strafed without clearance and had injured someone down range. We had no idea what was happening on the Eastern seaboard.” [Wolverine Guard, 9/2006 pdf file; Mount Clemens-Clinton-Harrison Journal, 9/6/2006]
Pilots Directed to Return to Base - According to author Lynn Spencer, because a commander with the 127th Wing agreed to turn the two F-16s over to NEADS (see (9:55 a.m.) September 11, 2001), Champagne and Froling are instructed to call NEADS. When they do so, they are ordered to intercept Delta 1989. [Spencer, 2008, pp. 178, 180, 188] But according to other accounts, they are “ordered south in case United Airlines 93 was targeting Chicago.” [ABC News, 9/11/2002; Post-Standard (Syracuse), 3/27/2005] However, according to two reports based on interviews with Champagne, Peplinski only instructs the two pilots to return to their base and land on its auxiliary runway.
Pilots Apparently Not Ordered to Intercept Aircraft - Accounts based on interviews with the pilots will make no mention of the jets being directed to intercept Delta 1989 or Flight 93. According to Champagne, the air traffic controller’s announcement that an aircraft hit the Pentagon “was the only indication we received that other aircraft and buildings were involved.” Champagne will say that “he and his colleague never received orders to intercept [Flight 93] in any way.” The two pilots “had no ammunition… and only an hour’s worth of fuel remaining. And as they approached Selfridge amid the puzzling radio transmissions, they still were oblivious to what was transpiring.” [Filson, 2003, pp. 68-70; Wolverine Guard, 9/2006 pdf file; Mount Clemens-Clinton-Harrison Journal, 9/6/2006]
Jets Land at Base - The two F-16s land back at Selfridge Air National Guard Base at 10:29 a.m. [9/11 Commission, 10/27/2003 pdf file] As Champagne pulls in his aircraft, his friend Captain Sean Campbell approaches and mouths the words to him: “It’s bad. It’s really, really bad.” [Wolverine Guard, 9/2006 pdf file; Mount Clemens-Clinton-Harrison Journal, 9/6/2006]

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.

NORAD’s Northeast Air Defense Sector (NEADS) contacts an Air National Guard unit in Toledo, Ohio, and requests that it launch two fighter jets in response to the attacks. [WTOL, 9/11/2006; Lynn Spencer, 2008; Spencer, 2008, pp. 178]
First Time that Unit Has Answered a NORAD Request - The 180th Fighter Wing of the Ohio Air National Guard is based at Toledo Express Airport. It has 20 F-16 fighter jets and about three dozen pilots. [Toledo Blade, 12/9/2001] Its “primary mission” is “to provide combat ready F-16C and support units capable of deploying worldwide in minimum response time.” [180th Fighter Wing, 9/19/2001; GlobalSecurity (.org.), 10/21/2001] The unit is not one of NORAD’s seven alert facilities around the US, and this is believed to be the first time it has ever answered a request for help from NORAD. [Airman, 12/1999; Toledo Blade, 12/9/2001]
Call due to Concern over Delta 1989 - According to author Lynn Spencer, a weapons technician at NEADS makes the call to the 180th FW due to concerns about Delta Air Lines Flight 1989, which is incorrectly thought to have been hijacked (see 9:39 a.m. September 11, 2001). [Spencer, 2008, pp. 177-178] NEADS has already contacted units in Minnesota and Michigan about this aircraft (see (Shortly After 9:41 a.m.) September 11, 2001 and (9:55 a.m.) September 11, 2001). [9/11 Commission, 1/23/2004 pdf file; Vanity Fair, 8/1/2006] The weapons technician calls the Toledo unit after Master Sergeant Joe McCain gives an update across the NEADS operations floor: “Delta [19]89! Hard right turn!” According to Spencer, the weapons technician knows the 180th FW is much better positioned than the Selfridge unit’s fighters are to reach Delta 1989. [Spencer, 2008, pp. 178]
NORAD Commander Gives Different Explanation - But according to Larry Arnold, the commander of the Continental United States NORAD Region, the weapons technician’s call might also be in response to concerns over Flight 93. Arnold will say that NEADS calls the 180th FW “because we thought [Flight] 93 or Delta Flight 1989 might be headed toward Chicago.” [Filson, 2003, pp. 71] Two Toledo pilots who initially answer the call from NEADS appear to believe the call is a joke, but their wing commander then picks up the line and responds appropriately (see 10:01 a.m. September 11, 2001). [Spencer, 2008, pp. 178-179]
Unit Prepared for Crisis Like This - Although it is not one of NORAD’s alert facilities, Lt. Col. Gary Chudzinski, a former commander of the 180th FW, will later comment that the Toledo unit has always been aware that it could be alerted to crises such as the current one, “but you just don’t expect it.” According to General Paul Sullivan, who heads all Ohio Air National Guard units, the 180th FW’s pilots practice “air interception,” but a typical mission focuses on either a plane ferrying drugs or enemy fighters approaching America’s coasts. [Airman, 12/1999; Toledo Blade, 12/9/2001] Two 180th FW jets will take off from the Toledo unit at 10:17 a.m. (see 10:17 a.m. September 11, 2001). [Toledo Blade, 12/9/2001; WTOL, 9/11/2006]

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]

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]

Tape recordings of the operations floor at NORAD’s Northeast Air Defense Sector (NEADS) indicate that some military personnel are uncertain whether a training exercise that was being conducted on this day has been canceled. NEADS has been participating in a major exercise called Vigilant Guardian. [Newhouse News Service, 1/25/2002] This was reportedly called off “shortly after” the second WTC tower was hit at 9:03 (see (Shortly After 9:03 a.m.) September 11, 2001). [Airman, 3/2002] But at 10:06, someone calls NEADS and asks, “Is the exercise knocked off?” to which they are told, “Yes.” Two minutes later, a member of the NEADS staff is heard saying, “If this is an exercise input, this is a good one.” [North American Aerospace Defense Command, 9/11/2001] It is around this time that NEADS is first alerted to Flight 93 (although this plane has already crashed) (see 10:05 a.m.-10:08 a.m. September 11, 2001) and also hears a report of an unidentified aircraft over the White House (see 10:07 a.m. September 11, 2001). So presumably it is one of these incidents that is considered a possible “exercise input,” meaning a simulated scenario. [Vanity Fair, 8/1/2006]

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).

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).

Air traffic controllers at the FAA’s Cleveland Center.Air traffic controllers at the FAA’s Cleveland Center. [Source: Paul M. Walsh]Most members of staff at the FAA’s Cleveland Center are evacuated from the facility, due to a report of a small aircraft flying erratically above the center. [Federal Aviation Administration, 3/21/2002, pp. S-19 pdf file; Newsnet5, 8/12/2002; Associated Press, 8/15/2002] The Cleveland Center, in Oberlin, Ohio, had the last contact with Flight 93 before it crashed. [Associated Press, 6/15/2002] The center’s air traffic controllers have been working on clearing the skies over the US after FAA facilities were ordered to instruct all aircraft to land at the nearest airport (see (9:45 a.m.) September 11, 2001). [Newsnet5, 8/12/2002; Lake County News-Herald, 9/10/2011]
Operations Manager Orders Evacuation - The police in Oberlin now contact the Cleveland Center and warn it about a small plane that is still airborne and circling above the facility. As a result, the decision is made to evacuate the center. [Federal Aviation Administration, 9/17/2001, pp. 9 pdf file; Associated Press, 8/15/2002; Cleveland Plain Dealer, 7/3/2011] The order to evacuate is apparently given by Leo Wolbers, the center’s operations manager. Wolbers will later recall, “[W]e made the decision to evacuate all non-essential personnel and get as many controllers out as possible.” He will say that he gathers together the supervisors at the center “to make sure they all knew to tell their controllers to get the planes down as quickly and safely as possible, and then leave the center.” [Federal Aviation Administration, 9/19/2001, pp. 6-7 pdf file; 9/11 Commission, 10/2/2003 pdf file] Non-essential personnel are sent home, while essential personnel who leave the building go to the parking lot. By 10:30 a.m., the facility will be running on a skeleton crew of eight controllers and eight supervisors.
Center Considered a Possible Terrorist Target - The Cleveland Center is evacuated “because someone feared the facility could be targeted for a terrorist attack,” according to the Cleveland Plain Dealer. [Federal Aviation Administration, 9/12/2001, pp. 70 pdf file; Cleveland Plain Dealer, 7/3/2011] But Bill Keaton, a controller at the center, thinks to himself that “the evacuation [is] a little silly.” He will comment: “Though Cleveland Center might be a great strategic target, it was an awful terrorist target. Most people have no idea what goes on at a [air traffic control] center, and the terrorists were striking symbolic targets… the World Trade Center, the Pentagon.” [Lorain Morning Journal, 9/11/2011]
Center Is Searched - Around the time it is being evacuated, the Cleveland Center is receiving a number of bomb threats (see 10:07 a.m.-10:21 a.m. September 11, 2001). [Federal Aviation Administration, 3/21/2002, pp. S-17, S-19 pdf file] Possibly in response to these, the building is searched, apparently during the period when many of its employees are outside in the parking lot. Wolbers will recall, “After we got all of our aircraft on the ground, we went to one person in each area until the building was searched and found to be secure.” [Federal Aviation Administration, 9/19/2001, pp. 6-7 pdf file] Around two hours after the evacuation, employees who left the building but have not gone home will go back inside and return to their posts. By then, though, the airspace will be empty, apart from some military aircraft, and so the controllers will have little to do. [Cleveland Plain Dealer, 7/3/2011]
Identity of Plane Unknown - The suspicious aircraft that prompted the evacuation is not identified. Rick Kettell, the manager of the Cleveland Center, will recall that it “flew off to the north and we lost radar on it.” Eleven months after 9/11, the FAA will reportedly still be investigating what the plane was and what it was doing.

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

Brigadier General Montague Winfield finally returns to his post as the deputy director for operations (DDO) in the National Military Command Center (NMCC) at the Pentagon, after leaving a colleague, who only recently qualified to take over the position, to stand in for him throughout the terrorist attacks. [9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 6/17/2004] At 8:30 a.m. Winfield left his post to attend a pre-scheduled meeting that was unrelated to the morning’s attacks and had been convened by the Air Force. Since that time, Captain Charles Leidig has replaced him as the DDO (see 8:30 a.m. September 11, 2001). Leidig, the deputy for Command Center operations, only qualified to stand in as the DDO in the NMCC about a month ago. Even though officers in the NMCC realized the US was under terrorist attack when the second plane hit the World Trade Center at 9:03 a.m., Winfield did not return to his post at that time (see (Shortly After 9:03 a.m.) September 11, 2001). [9/11 Commission, 7/21/2003 pdf file; 9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 6/17/2004 pdf file]
Winfield Returns to His Post, but Timing Unclear - Now Winfield finally relieves Leidig and resumes his duties as DDO. This happens after Flight 93 has crashed in Pennsylvania (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001), although the exact time is unclear. In a private interview with the 9/11 Commission, Leidig will say he is “certain that Winfield returned [from the meeting] after the Pentagon was hit” at 9:37 a.m. (see 9:37 a.m. September 11, 2001), but he “is not certain of Winfield’s arrival in relationship with the vice chairman” of the Joint Chiefs of Staff, General Richard Myers. [9/11 Commission, 4/29/2004 pdf file] (According to the 9/11 Commission Report, Myers arrived at the NMCC shortly before 10:00 a.m. (see (Between 9:55 a.m. and 10:25 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 38] ) Winfield then takes over as DDO “at some point in relation to the report of the Pennsylvania crash,” according to Leidig. As the 9/11 Commission will point out, since the crash of Flight 93 happened around 10:03 a.m., “any reporting would be after that time.” [9/11 Commission, 4/29/2004 pdf file] During a public hearing of the 9/11 Commission, Leidig will similarly say that Winfield takes over from him “[r]ight after we resolved what was going on with United 93.” He will also say that a report over the NMCC’s air threat conference at 10:37 a.m., about an anonymous threat against Air Force One (see (10:32 a.m.) September 11, 2001), occurs “right after I was relieved on the watch by General Winfield.” [9/11 Commission, 6/17/2004] This would indicate that Winfield takes over from Leidig at around 10:30 a.m.
Unclear If Winfield Returns to Post Immediately after Meeting - It is also unclear whether Winfield returns to his position as DDO immediately after leaving the Air Force-convened meeting, or he allowed Leidig to continue in his place even while he was available to resume his duties. A 9/11 Commission memorandum will state, “Winfield transitioned into the position [of DDO] upon his return to the NMCC,” following the meeting. [9/11 Commission, 7/21/2003 pdf file] Leidig will recall that he “looked up at one point and General Winfield was standing next to him.” He will also recall that Myers “looked at him at one time and realized the coordinator [i.e. the DDO] was not a general as the position called for, and asked who the general or admiral was that had duty that day.” The guidance that was subsequently given was “to get General Winfield briefed up and in the chair.”
Leidig Listens to Conference before Returning to Post - After Winfield returns to his position as DDO, Leidig initially “stands next to him and listens to the [NMCC’s air threat] conference.” Leidig will then transition into his regular job, which involves making sure the NMCC operates properly, and start dealing with the smoke coming into the center and other issues effecting operations there.

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).

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]

United Airlines issues a press release confirming that Flight 93 has crashed. Flight 93 went down in Pennsylvania shortly after 10:00 a.m. (see (10:06 a.m.) September 11, 2001). The release states: “United Airlines has confirmed one of its flights has crashed near Pittsburgh, Pennsylvania. United Flight 93, a Boeing 757 aircraft, is the flight number involved. The flight originated in Newark and was bound for San Francisco.” The release adds, “United is deeply concerned about a further flight, United Flight 175, a Boeing 767, which was bound from Boston to Los Angeles.” [United Airlines, 9/11/2001] Although Flight 175 hit the World Trade Center at 9:03 (see 9:03 a.m. September 11, 2001), United Airlines will not publicly confirm it has crashed until 11:53 a.m. (see 11:53 a.m. September 11, 2001).

United Airlines finally issues a press release confirming that Flight 175 has crashed, nearly three hours after this aircraft hit the World Trade Center (see 9:03 a.m. September 11, 2001). The release states, “United Airlines has now confirmed that two of its aircraft have crashed.” These include “United Flight 175, a Boeing 767 aircraft, [that] departed from Boston at 7:58 a.m. local time, bound for Los Angeles, with 56 passengers onboard, two pilots and seven flight attendants.” [United Airlines, 9/11/2001] United Airlines previously issued a press release, at 11:17, confirming the crash of Flight 93 (see 11:17 a.m. September 11, 2001), but this had stated that the airline was, at that time, only “deeply concerned” about Flight 175. [United Airlines, 9/11/2001] However, at 9:22, the United Airlines System Operations Control manager had issued an advisory to all the airline’s facilities, stating that Flight 175 had been in an accident in New York (see 9:22 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 26] And Colin Scoggins, the military liaison at the FAA’s Boston Center, will later claim that United confirmed to the center that Flight 175 was down, “within two or three minutes” (see (9:06 a.m.) September 11, 2001).

However, two of the four flight numbers it provides are wrong. [Draper, 2007, pp. 143] Yet, by late morning, American Airlines and United Airlines had already issued press releases confirming that the four planes that crashed were flights 11, 175, 77, and 93 (see 11:17 a.m. September 11, 2001, (11:18 a.m.) September 11, 2001, and 11:53 a.m. September 11, 2001).

Barry Mawn.Barry Mawn. [Source: Associated Press]On September 13, New York authorities take into custody ten people of Middle Eastern descent at JFK International and La Guardia Airports, reportedly fearing they intend to hijack aircraft and commit another suicidal terrorist attack on a US target. This leads to all three major New York-area airports—JFK, La Guardia, and Newark—being abruptly shut down, just hours after they reopened for the first time since the 9/11 attacks took place. [Associated Press, 9/14/2001; Dallas Morning News, 9/14/2001; New York Times, 9/14/2001; Washington Post, 9/14/2001]
Armed and Carrying False ID - According to the Washington Post, the detained individuals are carrying knives and false identification. [Washington Post, 9/14/2001] Four of them are reportedly arrested as they try to board a flight from JFK Airport to Los Angeles, and a woman is held on suspicion of assisting these four. Some of the four are reported as having pilots’ certificates from Flight Safety International in Vero Beach, Florida, where some of the alleged 9/11 hijackers are currently believed to have taken flying lessons. Later on, the other five men are arrested at La Guardia Airport “under similar circumstances.” [Dallas Morning News, 9/14/2001] According to the New York Times, “Law enforcement officials said one of those held was carrying a false pilot’s identification.” Furthermore, several of the detained men “showed up at the airport with tickets for flights canceled on Tuesday [September 11] and tried to use them.” Investigators say they believe one of the men had been among a group of passengers that behaved suspiciously and became aggressive after their aircraft—United Airlines Flight 23—had its takeoff canceled on the morning of 9/11 (see (After 9:19 a.m.) September 11, 2001). New York Police Commissioner Bernard Kerik says one of the men arrested at JFK Airport “attempted to clear security and he was stopped.” [New York Times, 9/14/2001]
Men Released, No Connections Found to 9/11 Attacks - However, the following morning the FBI announces that none of the detainees had any connection to the 9/11 attacks, and all but one of them have been released. Barry Mawn, the head of the New York FBI office, says: “The reporting that has been going on all night, I can definitively tell you, is inaccurate.… [W]e did talk to approximately a dozen individuals. We have only one individual left who is still being questioned by the task force. All other ten have been released.” [CNN, 9/14/2001; PBS, 9/14/2001] Justice Department spokeswoman Mindy Tucker says that no knives, box cutters, guns, or other weapons were found on the individuals. [Washington Post, 9/15/2001] After talking to the directors of the FBI and CIA, Senator Joseph Biden (D-DE) tells CNN that the detained men had “no connection whatsoever to what happened at the World Trade towers or the Pentagon, or this organizational network.” He explains: “One guy, an actual pilot, got on the plane, coincidentally had his brother’s identification as well. His brother happened to live in the apartment complex that was one in Boston where some of [the alleged hijackers] had actually been.” Biden adds: “Ten other people were going to a Boeing conference. They had stickers on their bags.… The folks at the airport thought, hey, wait a minute, are they impersonating crew? And they weren’t.” Biden says the one man who has not yet been released “was a screwball who was acting out, you know, acting out and saying and demanding.… Making problems, and they arrested him.” By 11:20 a.m. on September 14, the three New York-area airports are reopened.

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).

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).

The FBI claims on this day that there were six hijacking teams on the morning of 9/11. [New York Times, 9/19/2001; Guardian, 10/13/2001] A different report claims investigators are privately saying eight. [Independent, 9/25/2001] However, the reports below suggest there may have been as many as nine aborted flights, leading to a potential total of 13 hijackings:

Alternately, they may have been planning an attack for September 15, 2001. Their names are Mohammed Azmath and Ayub Ali Khan, whose real name according to later reports is Syed Gul Mohammad Shah. [New York Times, 9/19/2001]
bullet There may have been an attempt to hijack United Airlines Flight 23 flying from JFK Airport, New York to Los Angeles around 9:00 a.m. Shortly after 9:00 a.m., United Airlines flight dispatcher Ed Ballinger sent out a warning about the first WTC crash to the flights he was handling (see 9:19 a.m. September 11, 2001). Because of this warning, the crew of Flight 23 told the passengers it had a mechanical problem and immediately returned to the gate. Ballinger was later told by authorities that six men initially wouldn’t get off the plane. When the men finally disembarked, they disappeared into the crowd and never returned. Later, authorities checked their luggage and found copies of the Koran and al-Qaeda instruction sheets. [Associated Press, 9/14/2001; Chicago Daily Herald, 4/14/2004] In mid-2002, a NORAD deputy commander says “we don’t know for sure” if Flight 23 was to have been hijacked. [Globe and Mail, 6/13/2002]
bullet According to anonymous FAA officials, a plane bound for Chicago, home of the Sears Tower, could have been another target for hijacking. The plane landed unexpectedly at the Cleveland airport after the FAA initiated a national ground stop. Four Middle Eastern men had deplaned and left the airport before officials could detain them for questioning. [Freni, 2003, pp. 81]
bullet A box cutter knife was found under a seat cushion on American Airlines Flight 160, a 767 that would have flown from San Diego to New York on the morning of 9/11 but for the air ban. [Chicago Tribune, 9/23/2001]
The FBI is said to be seeking a number of passengers who failed to board the same, rescheduled flights when the grounding order on commercial planes in the US was lifted. [BBC, 9/18/2001] The Independent points out suspicions have been fueled “that staff at US airports may have played an active role in the conspiracy and helped the hijackers to circumvent airport security.” They also note, “It is possible that at least some of the flights that have come under scrutiny were used as decoys, or as fallback targets.” [Independent, 9/25/2001]

Mohammed Azmath, left, and Syed Gul Mohammad Shah/ Ayub Ali  Khan, right.Mohammed Azmath, left, and Syed Gul Mohammad Shah/ Ayub Ali Khan, right. [Source: Associated Press]The New York Times reports that, although 830 people have been arrested in the 9/11 terrorism investigation (a number that eventually exceeds between 1,200 and 2,000 (see November 5, 2001), there is no evidence that anyone now in custody was a conspirator in the 9/11 attacks. Furthermore, “none of the nearly 100 people still being sought by the [FBI] is seen as a major suspect.” Of all the people arrested, only four, Zacarias Moussaoui, Ayub Ali Khan, Mohammed Azmath, and Nabil al-Marabh, are likely connected to al-Qaeda. [New York Times, 10/21/2001] Three of those are later cleared of ties to al-Qaeda. After being kept in solitary confinement for more than eight months without seeing a judge or being assigned a lawyer, al-Marabh pleads guilty to the minor charge of entering the United States illegally (see September 3, 2002) and is deported to Syria (see January 2004). There is considerable evidence al-Marabh did have ties to al-Qaeda and even the 9/11 plot (see September 2000; January 2001-Summer 2001; January 2001-Summer 2001; Spring 2001; Early September 2001). [Washington Post, 6/12/2002; Canadian Broadcasting Corporation, 8/27/2002] On September 12, 2002, after a year in solitary confinement and four months before he was able to contact a lawyer, Mohammed Azmath pleads guilty to one count of credit card fraud, and is released with time served. Ayub Ali Khan, whose real name is apparently Syed Gul Mohammad Shah, is given a longer sentence for credit card fraud, but is released and deported by the end of 2002. [Village Voice, 9/25/2002; New York Times, 12/31/2002] By December 2002, only 6 are known to still be in custody, and none have been charged with any terrorist acts (see December 11, 2002). On September 24, 2001, Newsweek reported that “the FBI has privately estimated that more than 1,000 individuals—most of them foreign nationals—with suspected terrorist ties are currently living in the United States.” [Newsweek, 10/1/2001]

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]

Subash Gurung.Subash Gurung. [Source: CNN/Courtesy WLS-TV]A young Nepalese man named Subash Gurung is arrested at Chicago’s O’Hare airport trying to board a United Airlines flight to Omaha with numerous knives, a can of mace, and a stun gun. He is in the US on an expired student visa. He is unemployed at the time of his arrest. Gurung claims that he was in a hurry and was unaware of the knives and other items in his luggage. But CNN reports that Gurung gave as his address an apartment building in Chicago that was also used by one of two terror suspects arrested on September 12, 2001 (see September 19, 2001 and After and October 20, 2001). This individual, Ayub Ali Khan (whose real name is apparently Syed Gul Mohammad Shah), lived in New Jersey but also used a Chicago address. A CNN government source says “many phone calls were made to and from that apartment, and credit card bills were paid from that address.” After being released by local police on bond, Gurung will be re-arrested the following day by the FBI for a weapons violation. Despite the apparent link to Ayub Ali Khan, the FBI denies any terror connection: “There is no allegation that this incident involves any suspected terrorist activity.” [CNN, 11/5/2001; CNN, 11/6/2001] Gurung will be convicted of a weapons charge in October 2002, and then deported.
