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

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

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

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).

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

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

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

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.

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

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

The daily threat briefing at NORAD’s Northeast Air Defense Sector (NEADS) includes no indication of any increase in the terrorist threat level. Lieutenant Colonel Mark Stuart, an intelligence officer working in the NEADS battle cab, will tell the 9/11 Commission that for his threat briefing today, there is “‘zero’ intelligence available concerning any increase in the terrorist threat level.” He will say that a briefing two days ago, on September 9, similarly “contained nothing on the terrorist threat.” Stuart will say the last briefing at NEADS that mentioned the threat posed by Osama bin Laden was on July 14, “as part of the increased threat warning during summer 2001” (see July 14, 2001).

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

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

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

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

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

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

The Command Center immediately establishes a teleconference between the Boston, New York, and Cleveland air traffic control centers, so Boston can help the other centers understand what is happening, in case Flight 11 should enter their airspace. Minutes later, in line with the standard hijacking protocol, the Command Center will pass on word of the suspected hijacking to the FAA’s Washington headquarters (see 8:32 a.m. September 11, 2001).

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

A number of pilots with the 102nd Fighter Wing at Otis Air National Guard Base in Massachusetts are preparing to take off for a training mission and see two of their unit’s fighter jets being scrambled in response to the hijacked Flight 11, but they are not asked to respond to the emerging crisis themselves and continue with their preparations for the training mission. [102nd Fighter Wing, 2001; Richard, 2010, pp. 9-12]
Pilots Preparing for Training over the Atlantic - The pilots are preparing to fly a defensive counter-air mission in an area of military training airspace over the Atlantic Ocean, southeast of Long Island, known as “Whiskey 105.” [Richard, 2010, pp. 10, 12; Airman, 9/3/2011] According to most accounts, six of the 102nd Fighter Wing’s F-15 fighters will be participating in the training mission. [102nd Fighter Wing, 2001; North American Aerospace Defense Command, 9/11/2001; Cape Cod Times, 9/11/2006; Spencer, 2008, pp. 155] But Major Martin Richard, one of the pilots involved, will write in a 2010 book that eight of the unit’s F-15s take part in the mission. Richard will recall that after the coordination briefing for the training mission, he goes to the “life support shop” and puts on his flying gear, and then goes to the operations desk. There, the unit’s supervisor of flying, Lieutenant Colonel Jon Treacy, briefs the pilots preparing for the training mission on current weather and airfield updates, and gives them the status of a KC-135 tanker plane that will be refueling their fighters during the training mission. Richard then heads to his F-15, inspects it, and speaks to his crew chief.
Pilots Notice Commotion as Fighters Are Scrambled - As Richard starts his fighter’s engines, he notices a commotion on one side of the flight line ramp. He will recall: “The broken, disjointed communication over the ultra high frequency (UHF) radio indicated confusion. Members of the 102nd Security Forces Squadron, the cops, marshaled into protective positions. Two vehicles appeared with their blue emergency lights flashing. We all knew what was going on.” The 102nd Fighter Wing keeps a pair of F-15s on alert—armed, fueled up, and ready to take off within minutes of a scramble order—and, Richard will recall, “[T]he alert aircraft were being scrambled.” [Richard, 2010, pp. 10-11]
Pilots Watch Alert Fighters Take Off, but Unconcerned about This - The pilots preparing to take off for the training mission idle their engines and wait while the two alert fighters take off (see 8:46 a.m. September 11, 2001). [102nd Fighter Wing, 2001] Richard will describe: “I watched from my jet as the clamshell doors on the alert hangars opened, heard the alert jets’ engines whine to life, and saw them aggressively emerge from the facility like an eager predator in search of its prey. Suddenly, the command post announced, ‘Scramble!’ They blasted off, shattering the previously still, calm, peaceful morning.” [Richard, 2010, pp. 12] The pilots involved in the training mission are apparently unaware of why these fighters are being scrambled. [Cape Cod Times, 9/11/2006] Richard will recall: “I wasn’t too concerned when I saw the scrambled aircraft take off. We see many scrambles during the year and most all are just aircraft or vessels that can’t be identified but are friendly.” [102nd Fighter Wing, 2001]
Pilots Continue Preparing for Training - Once the two alert fighters are airborne, the pilots on the ground continue preparing for their training mission. “Back on the flight line,” Richard will recall, “I arranged my formation for takeoff and followed the standard procedures en route to our training area southwest of Martha’s Vineyard.” [Richard, 2010, pp. 12] Richard and the other pilots will begin their training mission in Whiskey 105 (see (9:00 a.m.-9:24 a.m.) September 11, 2001). They will only learn of the first crash at the World Trade Center and be recalled to their base at around 9:25 a.m. (see (9:25 a.m.-9:45 a.m.) September 11, 2001), and some of them will take off again to help protect US airspace, but that will only be after the terrorist attacks have ended (see (10:30 a.m.) September 11, 2001 and (Shortly After 10:30 a.m.) September 11, 2001).

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

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

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

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

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

Col. Jon Treacy, commander of the 101st Fighter Squadron at Otis, phones NORAD’s Northeast Air Defense Sector (NEADS) to report the FAA’s request for help and get authorization to launch fighters.

Major General Larry Arnold, the commander of the Continental United States NORAD Region (CONR), learns of the possible hijacking of Flight 11 after leaving a video teleconference, but initially thinks the reported hijacking is part of a NORAD training exercise. [Filson, 2002; Code One Magazine, 1/2002] Arnold, who is at CONR headquarters, at Tyndall Air Force Base, Florida, has been in the video teleconferencing room, participating in a teleconference with other senior NORAD officials (see (8:30 a.m.-8:40 a.m.) September 11, 2001). [9/11 Commission, 2/2/2004 pdf file; Spencer, 2008, pp. 31] Colonel Robert Marr, the battle commander at NORAD’s Northeast Air Defense Sector (NEADS), recently tried phoning Arnold to get authorization to scramble fighter jets in response to the hijacked Flight 11, but no one at CONR interrupted the teleconference to fetch Arnold, and so Marr left an urgent message for the CONR commander (see (8:38 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20; Spencer, 2008, pp. 31]
Note Informs Arnold of Hijacking - Arnold is now in the video teleconferencing room with Robert Del Toro, an intelligence officer with the 1st Air Force, discussing the just-concluded teleconference, when his executive officer, Kelley Duckett, hands him a note with Marr’s message on it. The note says the FAA’s Boston Center is reporting a hijacking and requesting assistance with it, and asks that Arnold phone Marr back immediately. [Filson, 2002; 9/11 Commission, 5/23/2003; 9/11 Commission, 2/2/2004 pdf file; 9/11 Commission, 2/3/2004 pdf file]
Arnold Thinks Hijacking Is 'Part of the Exercise' - NORAD is currently in the middle of a major training exercise called Vigilant Guardian. [Code One Magazine, 1/2002; Arkin, 2005, pp. 545] Arnold will later say that, as a result, when he learns of the possible hijacking: “The first thing that went through my mind was: ‘Is this part of the exercise? Is this some kind of a screw-up?’” [ABC News, 9/11/2002] According to author Lynn Spencer, “Even as NORAD’s commander for the continental United States, Arnold is not privy to everything concerning the exercise.” The exercise “is meant to test commanders also, to make sure that their war machine is operating as it should.”
Arnold Told Hijacking Is 'Real-World' - Since a simulated hijacking is scheduled as part of the day’s exercise (see (9:40 a.m.) September 11, 2001), Arnold asks Duckett, “Is this part of the exercise?” Duckett replies that the hijacking is real-world. [Spencer, 2008, pp. 38] Arnold will say that “understanding this is real-world is obviously important, so I rushed downstairs to our battle staff position.” [Filson, 2002] It occurs to Arnold that it has been many years since NORAD handled a hijacking (see February 11, 1993). He is relieved that, “because we were in the middle of an exercise,” he recently reviewed the protocol for what to do in response to a hijacking, and so “we were pretty well familiar with those procedures.” [9/11 Commission, 5/23/2003; Spencer, 2008, pp. 38] Arnold will promptly phone Marr and instruct him to go ahead and scramble fighters in response to the hijacking (see (8:42 a.m.) September 11, 2001).

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

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

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

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

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

Juarez / Defense Intelligence Agency]Lieutenant Colonel Mark Stuart, an intelligence officer at NORAD’s Northeast Air Defense Sector (NEADS), calls the National Military Joint Intelligence Center (NMJIC) at the Pentagon regarding the hijacking of Flight 11, but the center is unable to provide him with any more information than he already has. [9/11 Commission, 10/30/2003 pdf file] NEADS was alerted to the hijacking of Flight 11 at 8:37 a.m. (see (8:37 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] Stuart now calls the Air Force desk at the NMJIC about it. [9/11 Commission, 10/30/2003 pdf file] The NMJIC, located in the Joint Staff area of the Pentagon, constantly monitors worldwide developments for any looming crises that might require US involvement. [Washington Times, 9/25/1997; Joint Chiefs of Staff, 2/6/2006] It “forms the heart of timely intelligence support to national-level contingency operations,” according to James Clapper, a former director of the Defense Intelligence Agency. And during a crisis, it “serves as a clearinghouse for all requests for national-level intelligence information.” [Joint Forces Quarterly, 3/1994 pdf file] However, Stuart will later recall that the NMJIC can provide him with “no additional relevant information” on the hijacking. Stuart then calls Robert Del Toro, an intelligence officer with the 1st Air Force at Tyndall Air Force Base, Florida. But, Stuart will say, the 1st Air Force also has “no further information” about the hijacking. [9/11 Commission, 10/30/2003 pdf file]

An intelligence officer at NORAD’s Northeast Air Defense Sector (NEADS) checks the SIPRNET—the Department of Defense’s classified version of the Internet—for information relating to the hijacking of Flight 11, but finds none. [Northeast Air Defense Sector, 9/11/2001; 9/11 Commission, 10/30/2003 pdf file] NEADS was alerted to the hijacking of Flight 11 at 8:37 a.m. (see (8:37 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] Since then, Lieutenant Colonel Mark Stuart, an intelligence officer at NEADS, has contacted various facilities, in search of further information about it. He called the FBI’s Strategic Information and Operations Center (see (8:48 a.m.) September 11, 2001), the National Military Joint Intelligence Center at the Pentagon, and 1st Air Force headquarters in Florida (see (Shortly After 8:48 a.m.) September 11, 2001), but none of them had any additional information on the crisis. Stuart now informs Colonel Robert Marr, the battle commander at NEADS, of his efforts. He also directs a “Major Edick”—another intelligence officer at NEADS—to search the SIPRNET for information on the hijacking. However, Stuart will later say, Edick is unable to find any such information on the SIPRNET “that morning or afternoon.” [Northeast Air Defense Sector, 9/11/2001; 9/11 Commission, 10/30/2003 pdf file]

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

NEADS Calls New York Center - Master Sergeant Maureen Dooley, the leader of the ID techs, tells Watson: “Update New York! See if they lost altitude on that plane altogether.” Watson immediately calls the FAA’s New York Center and asks, “Did you just hear the information regarding the World Trade Center?” When the person who answers her call says no, Watson explains, “Being hit by an aircraft.” The person at New York Center says, “You’re kidding,” but Watson adds, “It’s on the world news.” [Vanity Fair, 8/1/2006] One of the NEADS technicians is finally able to display the live CNN coverage on one of the 15-foot screens at the front of the room.

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

[Washington Post, 9/15/2001; North American Aerospace Defense Command, 9/18/2001; 9/11 Commission, 7/24/2004, pp. 20] It is now eight minutes since the mission crew commander at NORAD’s Northeast Air Defense Sector (NEADS) ordered that the jets be launched (see 8:45 a.m. September 11, 2001). [Vanity Fair, 8/1/2006] It is 40 minutes since air traffic controllers had their last communication with Flight 11 (see 8:13 a.m. September 11, 2001), and 28 minutes since they became certain that the aircraft was hijacked (see (8:25 a.m.) September 11, 2001).

Possible news that a 737 just hit the World Trade Center. This is a real-world.… Continue taking the fighters down to the New York City area, JFK [International Airport] area, if you can. Make sure that the FAA clears it—your route all the way through.… Let’s press with this.” [Vanity Fair, 8/1/2006] Yet there will be conflicting reports of the fighters’ destination (see (8:53 a.m.-9:05 a.m.) September 11, 2001), with some accounts saying they are directed toward military-controlled airspace off the Long Island coast.

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

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

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

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

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

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

The minute Flight 175 hits the South Tower, fighter pilot Major Daniel Nash will recall, clear visibility allows him to see smoke pour out of Manhattan, even though NORAD will say he is 71 miles away from there. [Cape Cod Times, 8/21/2002] The other Otis pilot, Lieutenant Colonel Timothy Duffy, recalls, “We’re 60 miles out, and I could see the smoke from the towers.” They call NORAD’s Northeast Air Defense Sector (NEADS) for an update, and, as Duffy will recall: “At that point, they said the second aircraft just hit the World Trade Center. That was news to me. I thought we were still chasing American [Airlines Flight] 11.” [ABC News, 9/14/2002] In another account Duffy will relate: “It was right about then when they said the second aircraft had just hit the World Trade Center, which was quite a shock to both [Nash] and I, because we both thought there was only one aircraft out there. We were probably 70 miles or so out when the second one hit. So, we were just a matter of minutes away.” [BBC, 9/1/2002] He asks NEADS for clarification of their mission, but the request is met with “considerable confusion.” [Aviation Week and Space Technology, 6/3/2002] Bob Varcadipane, a Newark, New Jersey, air traffic controller who sees the Flight 175 crash, will claim: “I remember the two F-15s. They were there moments after the impact. And I was just—said to myself, ‘If only they could have gotten there a couple minutes earlier.’ They just missed it.” [MSNBC, 9/11/2002] However, the 9/11 Commission appears to believe that the pilots never get near New York City at this time. According to the Commission’s account, lacking a clear target, the Otis fighters took off toward military controlled airspace over the ocean, off the coast of Long Island. A map released by the Commission indicates that at 9:03 they are about 100 miles away and heading southwest instead of west to New York City. [9/11 Commission, 6/17/2004] Tape recordings of the NEADS operations floor reveal Major Kevin Nasypany telling Colonel Robert Marr, “Fighters are south of—just south of Long Island.” [Vanity Fair, 8/1/2006] The 9/11 Commission says that, at 9:10 a.m., the FAA’s Boston Center tells the Otis fighters about the second WTC tower being struck.

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

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

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

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

The two F-15s launched from Otis Air National Guard Base in response to Flight 11 finally exit their “holding pattern” off the Long Island coast, and fly directly toward New York. [9/11 Commission, 8/26/2004, pp. 26] According to the 9/11 Commission, the two fighters had been sent to the military-controlled airspace over the Atlantic Ocean because they lacked a target, and so have been flying in this area for the last few minutes (see 9:09 a.m.-9:13 a.m. September 11, 2001). They are currently about 115 miles from the city. [9/11 Commission, 7/24/2004, pp. 20 and 24] Visibility is extremely clear and Lt. Col. Timothy Duffy, one of the two Otis pilots, will later recall that he can see the World Trade Center towers burning in the distance. He has just called NORAD’s Northeast Air Defense Sector (NEADS) and asked: “What do you want me to do next? What do you need from me right this second?” [Cape Cod Times, 8/21/2002; Filson, 2003, pp. 63]
NEADS Takes Control of Airspace - At NEADS, battle commander Colonel Robert Marr had lost patience waiting for approval from the FAA to send the Otis jets to New York, and so has just declared “AFIO” (Authorization for Interceptor Operations) for New York airspace, which gives the military authority to enter that airspace without permission (see (9:12 a.m.) September 11, 2001). [Spencer, 2008, pp. 113] Therefore, a couple of minutes after Duffy made his inquiry, NEADS weapons controller Major Steve Hedrick gets back to him to relay the AFIO directive. Hedrick instructs Duffy: “Proceed direct to Manhattan and set up combat air patrol. NORAD has taken over control of the airspace.” Duffy confirms, “Okay, got that.”
Fighters Request Lower Altitude Clearance - Duffy, who is currently flying at 20,000 feet, immediately requests clearance from the FAA to fly at lower altitude. He calls its New York Center and identifies himself with his military call sign, saying, “Panta 4-5 needs to go direct to New York City and I need lower [altitude]… right now.” The controller gives him a heading and clears him to descend to 18,000 feet. After the two Otis jets exit military airspace at 9:13, they descend to 18,000 feet and Duffy asks the New York Center controller again for lower altitude clearance. He is given permission to descend to 16,000 feet, and upon further requests is allowed to go down to 11,000 feet. Finally, Duffy insists, “Guys, I need all the way to the surface!” and the controller replies: “Roger. Panta 4-5 is clear all altitudes.” “They just gave us the airspace,” Duffy will later recall. [Filson, 2003, pp. 63; Spencer, 2008, pp. 113-114]
Conflicting Times - According to the 9/11 Commission, the two Otis fighters will arrive over Manhattan at 9:25 (see 9:25 a.m. September 11, 2001), but numerous witnesses on the ground there will later recall only noticing fighters overhead after 10:00 a.m. (see (9:45 a.m.-10:45 a.m.) September 11, 2001).

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

Norman Seip.Norman Seip. [Source: US Air Force]A National Operations and Intelligence Watch Officer Network (NOIWON) conference call is established to allow government agencies in the Washington, DC, area to quickly share information regarding the ongoing events, but the call reportedly contributes little of value to the emergency response to the terrorist attacks. [Federal Aviation Administration, 9/11/2001; Federal Aviation Administration, 9/11/2001; 9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 7/13/2004; Government Executive, 6/1/2009] The NOIWON call is convened by the CIA sometime between 9:16 a.m. and 9:25 a.m., according to FAA chronologies. [Federal Aviation Administration, 9/11/2001; Federal Aviation Administration, 9/11/2001; Federal Aviation Administration, 9/17/2001 pdf file] According to an officer at the Pentagon, the White House Situation Room is taking the lead at the time he answers the NOIWON call. [9/11 Commission, 5/5/2004]
FAA Participates in Call - At the FAA headquarters in Washington, the NOIWON call is answered by Bart Merkley, one of two officers on duty in the ACI Watch—a small, 24-hour intelligence facility located on the building’s third floor. [9/11 Commission, 7/13/2004] Merkley stays on the call for its entire duration. He passes onto it information he has learned from the Tactical Net—a teleconference established by the operations center at FAA headquarters at 8:50 a.m. [Federal Aviation Administration, 9/17/2001 pdf file; 9/11 Commission, 5/19/2004]
NMCC Participates in Call - At the National Military Command Center (NMCC) at the Pentagon, the initial call on the NOIWON line is answered by Commander Pat Gardner, the assistant deputy director for operations. [9/11 Commission, 5/5/2004] Subsequently, Brigadier General Norman Seip will take over the line and remain on it for most of the day. According to a 9/11 Commission memorandum, this is because the “White House Situation Room insisted on having a flag officer on an open line” with it. [9/11 Commission, 7/21/2003 pdf file]
NOIWON Call of Little Use - The NOIWON call apparently contributes little of value to the emergency response to the terrorist attacks. Darrel Smith, who is working alongside Merkley in the ACI Watch at FAA headquarters, will tell the 9/11 Commission that he “does not remember any useful or significant information coming as a result of the NOIWON call.” [9/11 Commission, 7/13/2004] Captain Charles Leidig, the acting deputy director for operations in the NMCC throughout the attacks, will tell the Commission that he “recalled no situational awareness that came from the NOIWON call.” [9/11 Commission, 4/29/2004 pdf file] Gardner will say he “doesn’t remember specifically what was discussed” on the call. [9/11 Commission, 5/5/2004] FAA records will state, “It is believed that the [Department of Defense] received information” concerning the attacks over the NOIWON call, but the FAA “holds no records of that communication.” [Federal Aviation Administration, 9/11/2001]
Call Delays Establishing of NMCC's Conference - Furthermore, the NOIWON call delays the Pentagon’s response to the attacks. The NMCC’s usual first action in response to a crisis is to establish a “significant event conference” in order to gather and disseminate information from government agencies, and discuss what actions should be taken. However, the NOIWON call reportedly intervenes with the preparations for such a conference call. According to a 9/11 Commission memorandum, “The NMCC abandoned its attempt to convene a [significant event conference] so its watch officers could participate in the NOIWON conference.” [9/11 Commission, 7/21/2003 pdf file; 9/11 Commission, 6/17/2004] The significant event conference will therefore only commence at 9:29 a.m. (see 9:29 a.m.-9:34 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 37]
No Recording of Call - The NOIWON is described as “a dedicated secure telephone system with a conferencing capability for the rapid exchange and sharing of high interest and time-sensitive information between Washington-area operations centers.” [Government Executive, 6/1/2009] During breaking crises it is used by the major national security watch centers around Washington, including the NMCC and the National Military Joint Intelligence Center at the Pentagon, the State Department Operations Center, the State Department’s Bureau of Intelligence and Research, the CIA’s operations center, the NSA’s operations center, and the White House Situation Room. [Radi, 3/1997 pdf file] The 9/11 Commission will later request a transcript of the NOIWON call conducted on this day, but despite “multiple searches,” no recording of it will be found.

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

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

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

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

A number of fighter jets from Otis Air National Guard Base in Massachusetts that are out over the Atlantic Ocean on a training mission are notified of the first crash at the World Trade Center and then return to their base. The fighters belong to the 102nd Fighter Wing. [102nd Fighter Wing, 2001; 9/11 Commission, 1/7/2004 pdf file; Richard, 2010, pp. 13-14; Airman, 9/3/2011] According to most accounts, six of the unit’s F-15 fighters are taking part in the training mission. [102nd Fighter Wing, 2001; North American Aerospace Defense Command, 9/11/2001; Cape Cod Times, 9/11/2006; Spencer, 2008, pp. 155] But Major Martin Richard, one of the pilots involved, will write in a 2010 book that eight F-15s are taking part. [Richard, 2010, pp. 10]
Fighters Recalled for 'Possible Use' - The fighters took off from Otis Air Base at 9:00 a.m. for their “defensive counter-air” mission in an area of military training airspace over the Atlantic Ocean, southeast of Long Island, known as “Whiskey 105” (see (9:00 a.m.-9:24 a.m.) September 11, 2001). [9/11 Commission, 10/14/2003 pdf file; Airman, 9/3/2011] Following the second attack on the WTC at 9:03 a.m., commanders at Otis Air Base convened and decided to recall all aircraft out on training (see Shortly After 9:03 a.m. September 11, 2001). [Spencer, 2008, pp. 153-154] A member of staff at NORAD’s Northeast Air Defense Sector (NEADS) tells a colleague that the fighters in Whiskey 105 are being recalled to Otis for “possible use, so we’ve got more aircraft [on] standby.” [North American Aerospace Defense Command, 9/11/2001]
Controller Tells Fighters to Return to Base - The fighters are recalled to their base at around 9:25 a.m. [9/11 Commission, 10/14/2003 pdf file; 9/11 Commission, 1/7/2004 pdf file] Shortly after they arrive in Whiskey 105, Richard is called by an air traffic controller at the FAA’s Boston Center. [Cape Cod Times, 9/11/2006] Richard will later note that “for a controller to interrupt our training mission was out of the norm.” [Richard, 2010, pp. 13] According to Airman, the controller tells Richard: “There’s something going on in New York. I think you guys need to get back to your base.” [Airman, 9/3/2011] But Richard will recall that the controller says, “[A]n aircraft just crashed into the World Trade Center and I think you should return to base immediately.” Richard replies, “Copy,” meaning he understands. However, he will say: “I was a bit confused. I didn’t know the extent of the pandemonium residing just outside of our sterile training airspace.” [Richard, 2010, pp. 13]
Pilot Not Told Why Alert Jets Were Scrambled - Before taking off from Otis Air Base, Richard had seen the two of his unit’s fighters that are kept on “alert”—ready for immediate launch—taking off in response to the hijacked Flight 11 (see 8:46 a.m. September 11, 2001), but he had been unaware of why they were being scrambled (see (8:30 a.m.-8:59 a.m.) September 11, 2001). Therefore, Richard will recall, “When the FAA announced that the World Trade [Center] tower had been struck by an aircraft, I asked if this was why the alert pilots had been scrambled.” However, he will say, he “got no reply.” It is unclear whether the pilots on the training mission are informed of the aircraft hijackings at this time. Richard will recall, “[W]hen it came over the radio that it was a possible hijacking, it sure got our attention,” but he will not say when this radio communication occurs. [102nd Fighter Wing, 2001; Cape Cod Times, 9/11/2006]
Supervisor Tells Pilot to Get Back to Base - Richard hurriedly dials the radio frequency to contact Lieutenant Colonel Jon Treacy, his unit’s supervisor of flying, who controls flying operations from the ground. [Richard, 2010, pp. 13] Richard asks, “Do you need us back on base?” and Treacy replies, “Get back here as soon as you can.” [Cape Cod Times, 9/11/2006]
Fighters Have Too Much Fuel to Land - The fighters were split apart over the Whiskey 105 airspace for their training mission. Rather than spending time getting them back together, Richard orders the pilots to go back to base in flights of two jets. Furthermore, another problem will delay their return: the fighters all have too much fuel to be able to land. Therefore, Richard will write, “Rather than dump the fuel overboard, which would take upwards of six to nine minutes, we got together in twos and did some basic fighter maneuvering.” These maneuvers, which are done in full afterburner, are “the most expeditious way to get to landing weight.” As the pilots request clearance to fly out of Whiskey 105 and back to Otis Air Base, their radios become crowded with communications. Richard comments, “It sounds like we are at war.”
Pilots Told to Stay at Their Aircraft after Landing - The pilots still have little idea what is going on, so Richard contacts Treacy for an update. However, Treacy has nothing concrete to tell him and only says, “After you land, stay at your jets; we’ll run the classified packs out to you.” These “classified packs” fit into the leg pocket of a pilot’s g-suit, and include the classified codes and guidance pilots fly with when on alert. Richard will write, “In light of recent events, it seemed we had been drafted for alert duty.” [Richard, 2010, pp. 13-14]
Pilots Told to Prepare Fighters for Alert - The fighters arrive at Otis Air Base around 20 minutes after they are called back there, according to author Lynn Spencer. As they taxi in, the pilots receive an instruction over their radios from Treacy, who tells them, “Cock your jets for alert!” They have never received such an order before. It means that instead of parking and shutting down their aircraft, they must prepare them to be scrambled from the flight line, with all of the instruments, controls, and switches set ready for immediate takeoff orders. After doing as instructed, the pilots head into the operations building to find out what is happening. [Spencer, 2008, pp. 155] Most of the squadron personnel are huddled by the television in the break room, watching the coverage of the terrorist attacks. One of the life support technicians turns to Richard and says, “It’s a goddamn Tom Clancy novel!” Richard will comment, “It was obvious now that we were at war.” [Richard, 2010, pp. 14] A number of the fighters that come back from the training mission, which have no ordnance on them, will be armed and also refueled, ready to take off to protect US airspace. [102nd Fighter Wing, 2001] The first fighters to subsequently take off from Otis Air Base will launch at around 10:30 a.m. (see (10:30 a.m.) September 11, 2001 and (Shortly After 10:30 a.m.) September 11, 2001).

According to former counterterrorism “tsar” Richard Clarke, around this time the acting Chairman of the Joint Chiefs of Staff Richard Myers speaks to him via video link (see 9:28 a.m. September 11, 2001). During their conversation, Myers mentions, “We are in the middle of Vigilant Warrior, a NORAD exercise.” [Clarke, 2004, pp. 5] However, no other references have been found to this exercise, “Vigilant Warrior.” Considering that exercise terms are “normally an unclassified nickname,” [Chairman of the Joint Chiefs of Staff, 4/23/1998 pdf file] this is perhaps a little odd. Could Richard Clarke have mistakenly been referring to the Vigilant Guardian exercise (see (6:30 a.m.) September 11, 2001), which is taking place on 9/11? According to a later news report though, NORAD confirms that “it was running two mock drills on Sept. 11 at various radar sites and Command Centers in the United States and Canada,” one of these being Vigilant Guardian. [New Jersey Star-Ledger, 12/5/2003] If this is correct then there must be another NORAD exercise on 9/11. If not “Vigilant Warrior,” a possibility is that the exercise referred to by Richard Clarke is in fact “Amalgam Warrior,” which is a NORAD-sponsored, large-scale, live-fly air defense and air intercept field training exercise. Amalgam Warrior usually involves two or more NORAD regions and is held twice yearly, in the spring for the West Coast and in the autumn for the East Coast. [US Congress, n.d.; Airman, 1/1996; Arkin, 2005, pp. 254; GlobalSecurity (.org), 4/27/2005] Is it possible that in 2001 the East Coast Amalgam Warrior is being held earlier than usual (like Global Guardian (see 8:30 a.m. September 11, 2001)) and is taking place on 9/11? In support of this possibility is a 1997 Defense Department report that describes the Stratcom exercise Global Guardian, saying it “links with other exercise activities sponsored by the Chairman, Joint Chiefs of Staff, and the Unified Commands.” The exercises it links with are Crown Vigilance (an Air Combat Command exercise), Apollo Guardian (a US Space Command exercise), and—significantly—the NORAD exercises Vigilant Guardian and Amalgam Warrior. [US Department of Defense, 5/1997; GlobalSecurity (.org), 4/27/2005] Since in 2001, Vigilant Guardian (see (6:30 a.m.) September 11, 2001) is occurring the same time as Global Guardian, might Amalgam Warrior be as well? In his book Code Names, William Arkin says that Amalgam Warrior is “sometimes combined with Global Guardian.” [Arkin, 2005, pp. 254] Amalgam Warrior tests such activities as tracking, surveillance, air interception, employing rules of engagement, attack assessment, electronic warfare, and counter-cruise-missile operations. A previous Amalgam Warrior in 1996 involved such situations as tracking unknown aircraft that had incorrectly filed their flight plans or wandered off course, in-flight emergencies, terrorist aircraft attacks, and large-scale bomber strike missions. Amalgam Warrior 98-1 was NORAD’s largest ever exercise and involved six B-1B bombers being deployed to Eielson Air Force Base, Alaska, to act as an enemy threat by infiltrating the aerial borders of North America. [Airman, 1/1996; Arkin, 2005, pp. 254; GlobalSecurity (.org), 4/27/2005] Another Amalgam Warrior in fall 2000 similarly involved four B-1 bombers acting as enemy forces trying to invade Alaska, with NORAD going from tracking the unknown aircraft to sending up “alert” F-15s in response. [Eielson News Service, 10/27/2000; Associated Press, 10/29/2000] If either one (or both) of these exercises ending with the name “Warrior” is taking place on 9/11, this could be very significant, because the word “Warrior” indicates that the exercise is a Joint Chiefs of Staff-approved, Commander in Chief, NORAD-sponsored field training exercise. [North American Aerospace Defense Command, 8/25/1989] Real planes would be pretending to be threats to the US and real fighters would be deployed to defend against them.

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

According to the 9/11 Commission, by 9:30 a.m. American Airlines confirms that Flight 11 crashed into the World Trade Center. This is almost 45 minutes after the attack occurred. Earlier, at around 9:16, an American air traffic control specialist had only told the FAA that the airline “thought” the first plane to hit the WTC had been Flight 11 (see 9:16 a.m.-9:18 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 15-16] However, Colin Scoggins, a civilian manager at the FAA’s Boston Center, will later claim that American Airlines refused to confirm that its plane had hit the WTC for several hours afterwards. He will claim this lack of confirmation was a factor in his mistakenly reporting that Flight 11 was still airborne at 9:21 (see 9:21 a.m. September 11, 2001). He says, “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. With American Airlines, we could never confirm if it was down or not, so that left doubt in our minds.” [Vanity Fair, 8/1/2006] Yet American Airlines had the advantage over United that two of its flight attendants on Flight 11 had been in extensive contact by phone, up until a couple of minutes before their plane crashed. Amy Sweeney had been talking to Michael Woodward, a manager at the American Airlines flight services office at Boston’s Logan Airport (see 8:22 a.m.-8:24 a.m. September 11, 2001). And Betty Ong had been in contact with the airline’s Southeastern Reservations Office in North Carolina, with details of this call being continuously relayed to its System Operations Control (SOC) in Fort Worth, Texas (see 8:21 a.m. September 11, 2001).

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

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

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

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

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

Timothy Brown.Timothy Brown. [Source: Valorous Media, Inc.]Firefighter Timothy Brown, a supervisor at New York City’s Office of Emergency Management (OEM), tries calling the White House and other agencies in Washington, DC, about getting fighter jets to protect New York, but is unable to reach them. [Project Rebirth, 6/30/2002 pdf file; TEDx Talks, 10/7/2015] Brown headed to the Fire Department’s command post in the lobby of the North Tower after the first hijacked plane crashed into the World Trade Center, at 8:46 a.m. (see 8:46 a.m. September 11, 2001). After arriving there, he discussed the need to have fighters over New York with senior officials. [City of New York, 1/15/2002; Firehouse, 1/31/2003]
Firefighter Heard about an Additional Suspicious Aircraft - After the second hijacked plane crashed into the WTC, at 9:03 a.m. (see 9:03 a.m. September 11, 2001), personnel in the OEM’s Emergency Operations Center contacted the FAA and requested “air security” over New York (see (Shortly After 9:03 a.m.) September 11, 2001). [Jenkins and Edwards-Winslow, 9/2003, pp. 16 pdf file] Brown went to the lobby of the South Tower to help open a command post. [Project Rebirth, 6/30/2002 pdf file; TEDx Talks, 10/7/2015] While there, he will later recall, he heard over his radio that another suspicious aircraft was heading toward New York and that “we should be prepared to get hit again” (see (9:30 a.m.) September 11, 2001).
Firefighter Asks to Be Connected to the White House - At some point, he decides to try and call Washington, to make sure that New York will be getting air cover. [Firehouse, 1/31/2003] He goes to the phones in the southeast corner of the South Tower’s lobby and tries to find one that works. Eventually he finds one that has a dial tone. [City of New York, 1/15/2002; Project Rebirth, 6/30/2002 pdf file] He dials zero and then talks to the operator. [TEDx Talks, 10/7/2015] He tells her New York is under terrorist attack and he needs to talk to the White House to make sure the city has air cover.
Operator Cannot Reach Agencies in Washington - The operator tries hard to reach the White House. “She tried many different ways to get me through, many different offices in the White House,” Brown will recall. However, she is unable to get through, since the phones in Washington are overwhelmed. “Apparently [operators] had been getting a volume of phone calls similar to mine, of people trying to get through to federal agencies, trying to get help,” Brown will comment. [Project Rebirth, 6/30/2002 pdf file] Brown then learns from the operator about the attack on the Pentagon, which occurred at 9:37 a.m. (see 9:37 a.m. September 11, 2001). After failing to reach the White House, he says to her, “Well then get me the Pentagon” and she replies that the Pentagon has been attacked. “That’s the first time we knew it, knew that it was also under attack,” he will recall. [TEDx Talks, 10/7/2015] He also asks the operator to try and connect him to the Federal Emergency Management Agency (FEMA), which has its headquarters in Washington, but she is unable to reach it.
Firefighter Talks to the State Emergency Management Office - Finally, she is able to connect him to the New York State Emergency Management Office (SEMO) in Albany.

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

Johnstown-Cambria County Airport.Johnstown-Cambria County Airport. [Source: JMSA Today]At some time shortly before 10 a.m.—as early as 9:40 a.m. according to one report—air traffic manager Dennis Fritz, in the control tower at Johnstown-Cambria County Airport, 70 miles east of Pittsburgh, receives a call from Cleveland Air Traffic Control reporting a large, suspicious aircraft about 20 miles south of them, descending below six thousand feet. Despite the clear day, Fritz and his colleagues can see no plane approaching through binoculars. Soon afterwards, in response to another call from Cleveland, Fritz orders trainees and custodial staff to evacuate the tower, yet he is still unable to see any plane approaching. Less than a minute later, though, Cleveland calls a third time, saying to disregard the evacuation: The plane has turned south and they have lost radar contact with it.

Alice Hoglan, the mother of Mark Bingham, a passenger on Flight 93, informs the FBI that her son has just phoned her from the plane, and then calls Bingham’s cell phone and leaves two voicemail messages. [Federal Bureau of Investigation, 9/17/2001; Barrett, 2002, pp. 157-158] Alice Hoglan is currently staying at the home of her brother, Vaughn Hoglan, and his wife in Saratoga, California. [Longman, 2002, pp. 129; San Francisco Chronicle, 9/10/2003] Bingham has just called her and told her his flight was taken over by three men who said they had a bomb, but the call got broken off after less than three minutes (see (9:37 a.m.) September 11, 2001).

Bingham's Mother Realizes Flight 93 Will Likely Crash - No one in the Hoglan household was aware of the terrorist attacks in New York and at the Pentagon. But after the call from Bingham ends, Vaughn Hoglan switches on the television to see if there is any news about Flight 93 and the family sees, for the first time, the recorded footage of Flight 175 crashing into the World Trade Center (see 9:03 a.m. September 11, 2001). [BBC, 12/2001; Barrett, 2002, pp. 157] Alice Hoglan then realizes the hijacking of Flight 93 is part of a “grand and ugly scheme,” and that her son’s plane will likely crash, too. [San Francisco Chronicle, 1/28/2005; San Jose Mercury News, 9/10/2011]
Bingham's Mother Tells the FBI about the Hijacking - Being a flight attendant with United Airlines, she calls her airline to ask about her son’s plane. [Los Gatos Patch, 8/25/2011] However, she will later recall, all she gets is a recorded message, which states, “United Flight 93 left Newark at 8:01 a.m. and will arrive San Francisco, Gate 82, at 11:19 a.m.” [BBC, 12/2001] She also calls 9-1-1 to report what has happened. She is put through to the San Francisco division of the FBI and speaks to an agent there. [Federal Bureau of Investigation, 9/17/2001] The agent asks her a series of questions about the hijackers on Flight 93, but she is unable to answer them.
Bingham's Mother Leaves Messages for Her Son - Alice Hoglan then tries calling her son twice on his cell phone, intending to let him know the full scale of the attack that his plane’s hijacking is part of. On both occasions, she has to leave messages on his voicemail. She makes the first call at 9:54 a.m. (Because she is flustered, she miscalculates the East Coast time by an hour during the call and also mistakenly says Flight 93 might be used as a “target” rather than as a “weapon.”) She says: “Mark, this is your mom. It’s 10:54 a.m. [Eastern Time]. The news is that it’s been hijacked by terrorists. They are planning to probably use the plane as a target to hit some site on the ground. So, if you possibly can, try to overpower these guys if you can, ‘cause they will probably use the plane as a target. I would say go ahead and do everything you can to overpower them, because they’re hellbent. Try to call me back if you can. You know the number here. Okay, I love you sweetie. Bye.” A minute or so later she calls Bingham’s cell phone again and leaves a second, similar message. Among other things, she urges her son to “group some people and perhaps do the best you can to get control of [the plane].” [Barrett, 2002, pp. 157-158; San Jose Mercury News, 9/10/2011; McMillan, 2014, pp. 122] Bingham will never receive these messages.

An F-16C Fighting Falcon of the 148th Fighter Wing.An F-16C Fighting Falcon of the 148th Fighter Wing. [Source: Brett R. Ewald / US Air Force]NORAD’s Northeast Air Defense Sector (NEADS) tries to get fighter jets from a military unit in Duluth, Minnesota, sent after Delta Air Lines Flight 1989, but the unit is unable to respond. [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. [9/11 Commission, 2004; Vanity Fair, 8/1/2006]
NEADS Calls Duluth - The staff attempts to get a unit in Duluth to send jets toward the Delta flight. [9/11 Commission, 1/22/2004 pdf file; 9/11 Commission, 1/23/2004 pdf file] Presumably the unit they call is the 148th Fighter Wing of the Minnesota Air National Guard, which is located at the Duluth International Airport and flies the F-16 Fighting Falcon. [GlobalSecurity (.org), 8/21/2005] Unlike Otis Air National Guard Base and Langley Air Force Base, the 148th FW at Duluth is not one of NORAD’s seven “alert” sites around the US. However, its mission does include “air superiority and air defense functions.” [Airman, 12/1999; US Air Force, 2004; 9/11 Commission, 7/24/2004, pp. 17]
Duluth Has 'Nobody Available' - The Duluth unit is unable to respond to NEADS’s request for help. [9/11 Commission, 1/22/2004 pdf file] The reason for this is unclear. At 9:46 a.m., a member of staff on the NEADS operations floor will report that “Duluth has night flying, so there’s nobody available.” [North American Aerospace Defense Command, 9/11/2001; Donaldson and Johnson, 6/2008, pp. 47 pdf file] Marr will subsequently instruct NEADS personnel to contact every Air National Guard unit in the Northeast US with instructions to get their fighters airborne (see (Between 9:50 a.m. and 10:00 a.m.) September 11, 2001).

According to the accounts of numerous witnesses on the ground near the World Trade Center, military fighter jets are first noticed flying over Manhattan either shortly before or soon after the second collapse, at 10:28 a.m. Some witnesses recall fighters arriving just before this collapse:
bullet Emergency medical technicians Dulce McCorvey and Michael D’Angelo hear fighters flying over Manhattan at unspecified times after the first tower’s collapse. [City of New York, 10/3/2001; City of New York, 10/24/2001]
bullet Fire Lieutenant Sean O’Malley and firefighters Pete Giudetti and Dan Potter notice jet fighters flying overhead soon before the second collapse. [City of New York, 10/12/2001; City of New York, 12/6/2001; Smith, 2002, pp. 49-50]
Other witnesses say the fighters arrive soon after this collapse:
bullet Deputy Fire Chief Robert Browne, police officer Peter Moog, and emergency medical technicians Richard Zarrillo and Jason Katz notice fighters overhead immediately after, or fairly soon after, the second tower’s collapse. [City of New York, 10/24/2001; City of New York, 10/25/2001; City of New York, 12/20/2001; Fink and Mathias, 2002, pp. 79-80]
bullet Mayor Rudolph Giuliani, Police Commissioner Bernard Kerik, and Office of Emergency Management Director Richard Sheirer are heading north together after leaving their temporary command post on Barclay Street (see (9:50 a.m.-10:10 a.m.) September 11, 2001). In some accounts, all three of them recollect hearing the first military jets overhead soon after the second tower’s collapse. [Kerik, 2001, pp. 339-340; Giuliani, 2002, pp. 14; 9/11 Commission, 5/18/2004 pdf file] However, according to another account, Giuliani hears the first jet slightly earlier, at around 10:20 a.m. And, in his private testimony before the 9/11 Commission, Kerik claims to have heard a fighter jet coming when he was heading to the temporary command post on Barclay Street, i.e. shortly before 9:50 a.m. [Barrett and Collins, 2006, pp. 348-349]
A few witnesses claim the fighters arrive earlier on, before the first collapse at 9:59 a.m.:
bullet Emergency medical technician Frank Puma and Port Authority Freedom of Information Administrator Cathy Pavelec say they see fighter jets overhead at unspecified times before the first collapse. [City of New York, 12/12/2001; Fink and Mathias, 2002, pp. 68]
The fighter(s) are presumably the F-15s launched from Otis Air Force Base at 8:46 a.m. (see 8:46 a.m. September 11, 2001). However, the 9/11 Commission will claim that these arrived over Manhattan at 9:25 a.m. (see 9:25 a.m. September 11, 2001), which is significantly earlier than most of the witnesses on the ground recall.

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

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

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

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

I’m calling to say good-bye.” She says a “really nice person” next to her has handed her the phone and told her to call her family. News reports suggest this person is Lauren Grandcolas, who had been assigned a seat by Wainio in row 11 of the plane. [Pittsburgh Post-Gazette, 10/28/2001; Longman, 2002, pp. 167-168; MSNBC, 9/3/2002; MSNBC, 9/11/2006] But according to a summary of passenger phone calls presented at the 2006 Zacarias Moussaoui trial, Wainio and Grandcolas are now separated and sitting in different areas of the plane. Wainio is now in row 33 along with fellow passenger Marion Britton and an unnamed flight attendant. [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] According to some reports, Wainio is using a cell phone. Newsweek states that she actually tells her stepmother she is using a cell phone loaned to her by another passenger. [Newsweek, 9/22/2001; Chicago Tribune, 9/30/2001] But the Pittsburgh Post-Gazette claims she uses an Airfone. [Pittsburgh Post-Gazette, 10/28/2001] According to Longman, there are “long silences” throughout the call. [MSNBC, 7/30/2002] Heymann cannot hear anyone in the background: “She could not hear any conversation or crying or yelling or whimpering. Nothing.” [Longman, 2002, pp. 172] Longman describes that Heymann gets the feeling her stepdaughter is “resigned to what was going to happen to her. And that she actually seemed to be leaving her body, going to a better place. She had had two grandmothers who were deceased, and at one point she told her [step]mother, ‘They’re waiting for me.’” [MSNBC, 7/30/2002] Wainio also talks about her family, and says she is worried about how her brother and sister will handle this terrible news. [Longman, 2002, pp. 168] Accounts conflict over how long her call lasts and when it ends (see (Between 9:58 a.m. and 10:05 a.m.) September 11, 2001).

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).

An air traffic controller at the FAA’s Cleveland Center enters a new flight plan for Flight 93 into the FAA computer system, giving a new destination of Reagan National Airport in Washington, DC. Flight 93 is currently flying in the airspace covered by the Cleveland Center’s Imperial Sector radar position, which is being managed by controller Linda Justice. [Federal Aviation Administration, 9/11/2001; St. Petersburg Times, 9/12/2001; 9/11 Commission, 10/2/2003 pdf file; Lynn Spencer, 2008]
Controller Enters New Flight Plan for Flight 93 - Justice changes the flight’s destination code from “SFO,” the code for San Francisco International Airport, to “DCA,” the code for Ronald Reagan Washington National Airport. [St. Petersburg Times, 9/12/2001] An FAA chronology will specify that she changes the flight plan “direct HGR [the code for Hagerstown Regional Airport in Maryland] to DCA.” [Federal Aviation Administration, 9/11/2001] Another FAA chronology will similarly state that Justice reroutes Flight 93 “direct to Hagerstown direct to Washington National.” [Federal Aviation Administration, 12/6/2001] Flight 93’s tag therefore now reads, “Hagerstown—National,” according to Justice. [9/11 Commission, 10/2/2003 pdf file]
New Flight Plan Not Due to Communication with Pilot - The reason Justice enters a new flight plan for Flight 93 is unclear. A minute earlier, the hijacker pilot on Flight 93 reprogrammed the plane’s navigational system for the new destination of Reagan Airport (see 9:55 a.m. September 11, 2001). [Longman, 2002, pp. 182; 9/11 Commission, 7/24/2004, pp. 457] And according to the St. Petersburg Times, controllers typically only change a plane’s destination when this is requested by the pilots. [St. Petersburg Times, 9/12/2001] But one of the FAA chronologies will state that Justice’s change to the flight plan is “not a result of any communication with the pilot.” [Federal Aviation Administration, 9/11/2001]
Flight Plan Changed to Aid Handoff to Washington Controllers - Justice will later explain why she changes the flight plan. She will state that Flight 93 appears to be heading toward the airspace of the FAA’s Washington Center, and so, in “an attempt to expedite the situation,” she enters the change of routing to reflect Hagerstown Airport to Reagan Airport. She will say she does this “only to forward [the] information [about Flight 93] to the sectors the aircraft appeared to be tracking toward.” [Federal Aviation Administration, 9/12/2001 pdf file] Justice will tell the 9/11 Commission that she changes the routing when she sees Flight 93 is heading eastbound. She will say, “The easiest way to do a handoff is to change the flight plan,” and also say she changes the flight plan “to show that Washington Center was the recipient.” According to Justice, the “controversial step” she takes is “putting in Hagerstown, because the misconception was that she had communicated with the plane and cleared it through.” [9/11 Commission, 10/2/2003 pdf file] John Werth, another controller at the Cleveland Center, will tell the 9/11 Commission that Justice enters the new destination for Flight 93 “because she knew it would be easier to track the primary [radar track for the aircraft] when the computer has a flight plan to work with.” [9/11 Commission, 10/1/2003 pdf file] After changing the flight plan, Justice calls the Potomac Sector radar position at the Washington Center and tells the controller there to “pull up the data block” for Flight 93. Justice will say it is clear to the Washington Center controller that she has created the new destination in order to make it easier to locate the plane. [Federal Aviation Administration, 9/12/2001 pdf file; 9/11 Commission, 10/2/2003 pdf file]
New Flight Plan Causes False Reports of Plane Approaching Washington - According to author Lynn Spencer, the new flight plan creates a “coast track” of Flight 93 on the traffic situation displays at air traffic control facilities. “A coast track,” Spencer will write, “differs from a radar track in that it is not supported by radar returns but rather by a computer-generated, projected course for the flight. Although this track did not appear on controller radar screens, its presence on their [traffic situation displays] allowed Washington controllers to monitor the flight’s progression toward Washington.” According to Spencer, the presence of this coast track leads to incorrect reports of an aircraft approaching Washington in the minutes after Flight 93 crashes. She will write, “A controller in Washington, unaware that the flight had crashed, was calling position reports for the coast track of United 93 to the White House (see (Between 10:10 a.m. and 10:15 a.m.) September 11, 2001)… as well as the FBI at the Pentagon (where firefighters were evacuated and the firefight suspended in anticipation of a second impact)” (see (10:15 a.m.-10:38 a.m.) September 11, 2001).

We were told just to follow the president.” [Code One Magazine, 1/2002]

[Airman, 12/1999; Air Force Magazine, 2/2002]
Pilots Not Told What Their Target Is - Two of the F-16s sent toward Air Force One are on the ground at Ellington Field and have been placed on “battle stations,” with the pilots sitting in the cockpits, when the scramble order is received.

[American Defender, 12/2001 pdf file; Spencer, 2008, pp. 255] Among the four pilots are Shane Brotherton and Randy Roberts. Their new mission is so secret that their commander does not tell them where they are going. When they ask what their target is, the commander says, “You’ll know when you see it.” Brotherton will later recall, “I didn’t have any idea what we were going up [for] until that point.” [CBS News, 9/11/2002; Spencer, 2008, pp. 255]
Jets First to Reach Air Force One - At least two of the 147th Fighter Wing F-16s will be seen from Air Force One at around 11:30 a.m., although an official will tell reporters on board that fighters are escorting the plane about 15 minutes before that time (see (11:29 a.m.) September 11, 2001).

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

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

Just after President Bush authorizes the military to shoot down threatening aircraft, he speaks with Secretary of Defense Donald Rumsfeld about this, according to some accounts. According to the Washington Post, Bush gave the shootdown authorization after taking off on Air Force One (see (Shortly After 9:56 a.m.) September 11, 2001). He then talks “to Rumsfeld to clarify the procedures military pilots should follow in trying to force an unresponsive plane to the ground before opening fire on it. First, pilots would seek to make radio contact with the other plane and tell the pilot to land at a specific location. If that failed, the pilots were to use visual signals. These included having the fighters fly in front of the other plane. If the plane continued heading toward what was seen as a significant target with apparently hostile intent, the US pilot would have the authority to shoot it down.” [Washington Post, 1/27/2002] Journalist and author Bill Sammon will give a similar account, saying that, having spoken with Vice President Dick Cheney soon after Air Force One took off, Bush “then explained the shootdown order to Donald Rumsfeld, who was at the still-burning Pentagon.” [Sammon, 2002, pp. 102] The 9/11 Commission will concur that the “president apparently spoke to Secretary Rumsfeld for the first time… shortly after 10:00.” However, contradicting earlier accounts, it will say, “No one can recall the content of this conversation, but it was a brief call in which the subject of shootdown authority was not discussed” (see (10:00 a.m.-10:30 a.m.) September 11, 2001). According to the Commission, furthermore, the phone call between Bush and Cheney where the president gives the shootdown authorization is not until 10:18 (see 10:18 a.m.-10:20 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 41 and 43] Bush’s senior adviser Karl Rove, who is on Air Force One with the president, will also say this critical call occurs “at about 10:20,” and add that, after it, Bush reports that he has just talked to Rumsfeld as well as Cheney. [MSNBC, 9/11/2002] Rumsfeld will indicate he first learns that shootdown authorization has been given from Cheney rather than Bush, telling the 9/11 Commission that the vice president “informed me of the president’s authorization to shoot down hostile aircraft” over the air threat conference call. [9/11 Commission, 3/23/2004] The conversation he is referring to does not occur until 10:39 a.m. (see 10:39 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 43]

General Henry Shelton, the chairman of the Joint Chiefs of Staff, talks over the phone with General Richard Myers, the vice chairman of the Joint Chiefs of Staff, who is at the Pentagon, and is given information about the Pentagon attack and the military’s response to the terrorist attacks. Shelton took off at 7:15 a.m. to fly to Europe for a NATO conference (see 7:15 a.m. September 11, 2001). He learned of the attacks in New York while his plane was over the Atlantic Ocean, and has just been told of a “big explosion at the Pentagon” (see (8:50 a.m.-10:00 a.m.) September 11, 2001).
First Report Is of a Hand Grenade Going Off at Pentagon - Shelton heads to the communications console just behind the plane’s cockpit. From there, he talks over a secure, encrypted phone line with Myers, who is in the National Military Command Center (NMCC) at the Pentagon. Myers updates Shelton on what is known about the explosion at the Pentagon. He says the first report is that a hand grenade went off in the Pentagon parking lot.
Myers Updates Shelton on Military Response to Attacks - Myers then gives Shelton a complete status report. He says: “We’ve transitioned the SIEC [significant event conference] into an air threat conference call, which is in progress as we speak (see 9:29 a.m.-9:34 a.m. September 11, 2001 and 9:37 a.m.-9:39 a.m. September 11, 2001). FAA has requested that NORAD take over control of US airspace. Fighters have scrambled to escort Air Force One (see (After 9:56 a.m.) September 11, 2001) and we’re sending AWACS up to provide further monitoring (see Before 9:55 a.m. September 11, 2001). We’ve escalated to Threatcon Delta and are about to launch the NAOC [National Airborne Operations Center plane]. Bases around the world are locked tight, [Deputy Secretary of Defense Paul] Wolfowitz has been relocated to Site R (see (11:00 a.m.) September 11, 2001), plus, [Deputy National Security Adviser Stephen] Hadley has requested we implement full ‘Continuity of Government measures’ (see 9:59 a.m. September 11, 2001), and we are proceeding along those lines.”
Myers Says Plane Hit the Pentagon - Myers is then interrupted by some commotion in the background. When he returns to the line, he tells Shelton, “Okay, we just got the word: the prior report was incorrect; it was not a hand grenade that exploded, it was another commercial airline that struck the Pentagon.” He then continues with his status report, saying, “[P]er the president, we’ve gone weapons free in the event of a hijacked aircraft or one that threatens the White House.” [Giesemann, 2008, pp. 20, 22-24; Shelton, Levinson, and McConnell, 2010, pp. 430-433]
Shelton Wants to Return to Washington - Myers will tell the 9/11 Commission that after he arrives at the NMCC—presumably referring to the time of this phone call—he “recommended General Shelton return to Washington, DC.” [9/11 Commission, 6/17/2004 pdf file] But Shelton will recall that he tells Myers, “I need you to call Ed Eberhart [General Ralph Eberhart, the commander of NORAD] at NORAD and let him know that we’re coming back [to Washington] on Speckled Trout [the nickname of the plane he is on], and tell him that I would consider it a personal favor if he would see to it that the chairman and his crew are not shot down on their way back to Andrews.” Myers confirms, “Will do.” According to Shelton, his plane is called back 10 minutes later “with confirmation that we had been officially cleared to fly through the shutdown airspace.” [Shelton, Levinson, and McConnell, 2010, pp. 433] But according to Captain Rob Pedersen, the flight navigator on Shelton’s plane, it is several hours before the plane is cleared to enter the US airspace (see (After 9:45 a.m.) September 11, 2001). [Air Force Magazine, 9/2011 pdf file] The plane will therefore only land at Andrews Air Force Base, near Washington, at 4:40 p.m. (see 4:40 p.m. September 11, 2001) and Shelton will only arrive at the NMCC an hour after that (see 5:40 p.m. September 11, 2001). [Federal Aviation Administration, 9/11/2001 pdf file; Myers, 2009, pp. 159] The exact time of the call between Shelton and Myers is unclear, though it would be at some time after about 10:00 a.m., when Myers arrives at the NMCC (see (Between 9:55 a.m. and 10:25 a.m.) September 11, 2001).

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

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

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

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

[Source: Keith Srakocic/ Associated Press]Flight 93 crashes into an empty field just north of the Somerset County Airport, about 80 miles southeast of Pittsburgh, 124 miles or 15 minutes from Washington, D.C. Presumably, hijackers Ziad Jarrah, Ahmed Alhaznawi, Ahmed Alnami, Saeed Alghamdi, and all the plane’s passengers are killed instantly.

[Pittsburgh Tribune-Review, 9/12/2001; St. Petersburg Times, 9/12/2001; Pittsburgh Tribune-Review, 9/11/2002] Being “reclaimed” means the earth had been excavated down to the coal seam, the coal removed, and then the earth replaced and planted over.

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).

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

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).

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

[Source: Jon Culberson]At around 10:15 a.m., fire and rescue workers at the Pentagon in response to the attack there are evacuated away from the site, due to a warning of another hijacked aircraft flying towards Washington, DC, currently 20 minutes away. The warning is passed on by Special Agent Chris Combs, the FBI’s representative at the Pentagon crash site. Assistant Fire Chief James Schwartz then orders the fire and rescue personnel to evacuate to a highway overpass several hundred yards from the Pentagon. Combs receives the information about the inbound aircraft from the FBI’s Washington Field Office, which is in direct contact with the FAA. He then confirms it with the control tower at Washington’s Reagan National Airport. According to a report put out by the government of Arlington County, Virginia, updates are announced of the approaching aircraft “until the last warning when [it] went below radar coverage in Pennsylvania, an estimated 4 minutes flying time from the Pentagon.” [US Department of Health and Human Services, 7/2002, pp. A16 and A30 pdf file; 9/11 Commission, 7/24/2004, pp. 315] Yet if the timing of this account is correct, the approaching plane could not have been Flight 93, which crashed in Pennsylvania considerably earlier (see (10:03 a.m.-10:10 a.m.) September 11, 2001). Finally, Combs is informed by Jim Rice, his boss at the Washington Field Office, “You’re all clear.” Rice adds, incorrectly, “The plane hit Camp David.” [Creed and Newman, 2008, pp. 131] At 10:38, firefighters and rescue workers are allowed to return to the Pentagon and resume their activities. [Fire Engineering, 11/2002] There will be two more evacuations of the Pentagon site in the following 24 hours, also due to false alarms over reports of unidentified inbound aircraft (see (2:00 p.m.) September 11, 2001 and (10:00 a.m.) September 12, 2001).

Two Pentagon police officers see people—some of them members of the military—stealing crash debris from in front of the Pentagon. After the Pentagon was hit, Lt. Robbie Turner had been helping the injured at a triage area. When, at around 10:15 a.m., reports are received of a possible second plane heading for the Pentagon (see (10:15 a.m.-10:38 a.m.) September 11, 2001), he sets about evacuating people away from there. As this is going on, he later recalls: “[W]e had to try to collect up evidence, as much of the evidence as we possibly could. Take pictures of it or whatever.” However, some people are apparently trying to steal plane debris from the road in front of the Pentagon. According to Turner, “[W]e had to try to stop other people from pilfering the wreckage because, believe it or not, there were people—military personnel involved—you know, included, rather, that was picking up the wreckage of the plane from off the highway as we were running away.” [Library of Congress, 12/3/2001] Later on in the day, around 3:00 p.m., another Pentagon police officer, Roosevelt Roberts Jr., is called to the heliport near where the Pentagon was hit, and remains there for the next 13 hours. He will recall that, during this time, “we had a lot of people vandalizing, stealing evidence.” He does not specify who these people are, or what this “evidence” is that is being stolen and vandalized.

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

In a phone call with Vice President Dick Cheney, President Bush authorizes the military to shoot down hostile aircraft. Minutes earlier, in the Presidential Emergency Operations Center (PEOC) below the White House, a military aide had asked Cheney for the authority to engage what appeared to be an inbound aircraft, and Cheney had promptly given it (see (Between 10:10 a.m. and 10:15 a.m.) September 11, 2001). During a subsequent quiet moment, deputy White House chief of staff Josh Bolten, who is also in the PEOC, suggested to Cheney that he contact the president to confirm the engage order. Therefore at 10:18 a.m., according to White House logs, Cheney calls Bush, who is on board Air Force One, and speaks with him for two minutes. White House press secretary Ari Fleischer notes that at 10:20 a.m., Bush informs him that he has authorized the shootdown of aircraft, if necessary. According to the 9/11 Commission, “Fleischer’s 10:20 note is the first mention of shootdown authority.” [9/11 Commission, 7/24/2004, pp. 41 and 465] Bush’s senior adviser Karl Rove, who is also on Air Force One, gives a similar account, later telling NBC News that “at about 10:20,” Bush goes from his office into the private cabin in front of it, “and took a phone call, and came back in and said that he had talked to the vice president and to the secretary of defense and gave the authorization that [the] military could shoot down any planes not under control of their crews that were gearing critical targets.” [MSNBC, 9/11/2002] But other accounts indicate the president gives the shootdown authorization earlier than this. Bush and Cheney will claim that Bush gives the authorization during a call estimated to occur between about 10:00 and 10:15 (see (Between 10:00 a.m. and 10:15 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 40] Similarly, according to journalists Bob Woodward and Bill Sammon, Bush gives it in a call with Cheney soon after 9:56, when Air Force One takes off (see (Shortly After 9:56 a.m.) September 11, 2001). [Sammon, 2002, pp. 102; Woodward, 2002, pp. 17-18; Washington Post, 1/27/2002] Counterterrorism “tsar” Richard Clarke says it is given even earlier. He states that, at some point between about 9:38 and 9:56, he is instructed to tell the Pentagon it has authorization from the president to shoot down hostile aircraft (see (9:38 a.m.) September 11, 2001 and (Between 9:45 a.m. and 9:56 a.m.) September 11, 2001).

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

The FAA’s Boston Center is evacuated after it receives a report that an unidentified aircraft is heading its way. [Federal Aviation Administration, 9/20/2001; USA Today, 8/11/2002; New Hampshire Union Leader, 9/11/2006; Spencer, 2008, pp. 243] The Boston Center, located in Nashua, New Hampshire, manages air traffic above New England, and monitored Flight 11 and Flight 175 earlier on. [USA Today, 8/11/2002; Associated Press, 8/12/2002] Employees there are already concerned because a large tractor-trailer has parked directly in front of their facility, on New Hampshire’s Route 3. State police have been called to get it away from there.
Possible Airborne Threat Leads to Evacuation - The FAA’s New England regional office in Burlington, Massachusetts, now calls the Boston Center and reports that an unidentified aircraft is heading for the facility. In response to this potential threat, managers at the center immediately order the closure and evacuation of their building. They also declare “ATC zero,” which shuts down the Boston Center’s airspace (see (Shortly After 10:20 a.m.) September 11, 2001). Employees run from the building while managers try to decide which, if any, personnel should remain in the facility. According to Colin Scoggins, the center’s military liaison, “at this time we honestly felt that we were targeted and an impact was imminent.”
Bomb Threat to Childcare Facility - Making matters worse, a bomb scare phone call is received at the center’s childcare facility, which is the employees’ usual evacuation point. Center managers therefore decide that everyone must leave the building. Employees are advised to go to either 11 Murphy Drive—an FAA administrative facility—or a nearby Holiday Inn. According to Scoggins, three or four Flight Service Data Processing System personnel remain in the basement of the Boston Center when it is evacuated, apparently because there is no paging system in their office on which they can receive the evacuation order.
Evacuation Time Unclear - The time the evacuation takes place at is unclear. According to the account of author Lynn Spencer, it occurs some time shortly after 10:20 a.m. [Federal Aviation Administration, 9/20/2001; USA Today, 8/11/2002; Spencer, 2008, pp. 242-243] At 10:34 a.m., John White, a manager at the FAA’s Command Center, reports that the Boston Center “has received a threat,” and is “going down to skeleton staffing.” [9/11 Commission, 11/4/2003] A 10:52 a.m. entry in the log of the FAA headquarters’ teleconference will state that the Boston Center is “evacuating the building.” [Federal Aviation Administration, 3/21/2002 pdf file] USA Today will report that the center is evacuated at “about 11 a.m.”
Few Employees Return to Building - About 30 minutes to an hour after the building is evacuated, some of the center’s personnel will return to work. [Federal Aviation Administration, 9/20/2001; USA Today, 8/11/2002] By 12:16 p.m., the center is back in operation, but with only a skeleton staff. [Federal Aviation Administration, 3/21/2002 pdf file]
Suspicious Aircraft Only a Coast Guard Plane - As it turns out, the approaching aircraft that prompts the evacuation is just a Coast Guard plane. According to Scoggins, “We had already identified it.” [Federal Aviation Administration, 9/20/2001] The aircraft was noted in a 10:18 a.m. entry in the log of the FAA headquarters’ teleconference, which stated: “Aircraft 160 miles east of Nantucket is headed westbound toward Boston at a high rate of speed.” But a log entry five minutes later, at 10:23 a.m., noted that the aircraft “is identified as a Coast Guard flight from Nantucket.” [Federal Aviation Administration, 3/21/2002 pdf file] Shortly before the Boston Center is alerted to this aircraft, Scoggins had been tracking what is apparently another unidentified target on his radar screen: a slow-moving large aircraft that is also flying toward the Boston Center from the east (see (10:20 a.m.) September 11, 2001). [Spencer, 2008, pp. 242-243] The identity of that aircraft is unclear.

The Moncton Area Control Center.The Moncton Area Control Center. [Source: Nav Canada]Colin Scoggins, the military liaison at the FAA’s Boston Center, contacts NORAD’s Northeast Air Defense Sector (NEADS) and a Canadian air traffic control facility, to let them know that the Boston Center is shutting down its airspace and being evacuated, due to a possible airborne threat.
Scoggins Does Not Immediately Evacuate - The Boston Center in Nashua, New Hampshire, has just received a call from the FAA’s New England regional office, alerting it to an unidentified aircraft heading its way. In response, the center’s managers ordered the evacuation of the facility (see (Shortly After 10:20 a.m.) September 11, 2001) and declared “ATC zero,” which completely shuts down the center’s airspace (see (Shortly After 10:20 a.m.) September 11, 2001). But while others leave the building, Scoggins stays behind to make two phone calls.
Scoggins Calls Canadian Facility and NEADS - His first call is to the Moncton Center, which is the Canadian air traffic control facility that handles flights arriving from over the Atlantic. He tells a supervisor there, “We’re going to ATC zero and evacuating.” Scoggins then calls NEADS with the same information. He says: “I wanted to let you know, Boston Center has declared ATC zero and we are evacuating due to an airborne threat. It’s approaching Martha’s Vineyard and it’s coming our way.” Before hanging up, he gives NEADS the speed and coordinates of the approaching aircraft. Scoggins then heads out of the building. According to the account of author Lynn Spencer, Scoggins’s call prompts NEADS to immediately call Otis Air National Guard Base in Cape Cod, Massachusetts, and order it: “Get everything you’ve got in the air! Now!” (see (10:20 a.m.) September 11, 2001).
FBI and SWAT Teams Surround Center - By the time Scoggins is outside the Boston Center, FBI and SWAT teams are surrounding the facility. Scoggins will later recall that he sees the “Nashua SWAT team in the parking lot with automatic weapons, [and] the FBI running with the audio tapes with Bob Jones [a quality assurance specialist at the Boston Center] by their side.” [Federal Aviation Administration, 9/20/2001; Spencer, 2008, pp. 243-245] (The FBI reportedly arrived at the Boston Center “minutes after Flight 11 crashed into the World Trade Center,” and seized tape recordings of radio transmissions from the hijacked plane (see Soon after 8:46 a.m. September 11, 2001). [Christian Science Monitor, 9/13/2001] )
Scoggins Tracking Other Unidentified Plane - Before the Boston Center received the call from the FAA regional office about the approaching aircraft, Scoggins was tracking another unidentified target on his radar screen: a slow-moving aircraft also flying toward the center from the east (see (10:20 a.m.) September 11, 2001). Whether he alerts NEADS to that aircraft when he calls it is unclear. [Spencer, 2008, pp. 242-243]

Footage of the World Trade Center plays on the televisions in the background (exact time is unknown). [Source: White House]Those inside the Presidential Emergency Operations Center (PEOC) below the White House learn that an aircraft is down in Pennsylvania. (This turns out to be Flight 93.) Many of the people in the PEOC wonder whether military fighters shot it down. [Washington Post, 1/27/2002; 9/11 Commission, 7/24/2004, pp. 41] National Security Adviser Condoleezza Rice later claims that, like her, Vice President Dick Cheney initially thinks, “it must have been shot down by the fighters.” [Hayes, 2007, pp. 339] However, Eric Edelman—Cheney’s national security adviser, who is also in the PEOC—will later recall: “The vice president was a little bit ahead of us.… He said, sort of softly, and to nobody in particular, ‘I think an act of heroism just took place on that plane.’” [CNN, 9/11/2002; CNN, 9/14/2002] Yet the Pentagon does not confirm that Flight 93 was not shot down until after midday (see (Shortly After 12:00 p.m.) September 11, 2001). [Newsweek, 12/31/2001] And the phone calls from Flight 93 that indicated a passenger revolt took place are only reported later on. [Washington Post, 1/27/2002]
