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

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

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

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

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

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). [New York Times, 10/16/2001; MSNBC, 9/11/2002; 9/11 Commission, 7/24/2004, pp. 18; 9/11 Commission, 8/26/2004, pp. 7 and 10-11]

FAA’s Boston CenterFAA’s Boston Center [Source: ABC News]According to some reports, Boston flight control decides that Flight 11 has probably been hijacked, but apparently, it does not notify other flight control centers for another five minutes, and does not notify NORAD for approximately 20 minutes. [New York Times, 9/15/2001; Newsday, 9/23/2001] ABC News will later say, “There doesn’t seem to have been alarm bells going off, [flight] controllers getting on with law enforcement or the military. There’s a gap there that will have to be investigated.” [ABC News, 9/14/2001] (Note the conflicting account at 8:21 a.m. (see (8:21 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.

American Airlines has problems contacting the FAA’s Command Center in Herndon, Virginia, about the problems with its aircraft, according to four managers working at the airline’s System Operations Control (SOC) center in Fort Worth, Texas, on this day. Craig Marquis, Craig Parfitt, Joe Bertapelle, and Mike Mulcahy will later tell the 9/11 Commission that American Airlines has “a hard time on 9/11 in getting in touch with Herndon.” They will say that “[p]recious minutes were lost in building the communications bridge” between the SOC and the Command Center. The cause of these communication problems is unknown. [9/11 Commission, 11/19/2003 pdf file] The SOC has known that there are problems on Flight 11 since 8:21 a.m., when Marquis received a call from a supervisor at the airline’s Southeastern Reservations Office in North Carolina, alerting him to a call that had been received from one of the plane’s flight attendants about the emergency taking place (see 8:21 a.m. September 11, 2001). Presumably the SOC starts trying to contact the FAA Command Center soon after receiving this call. It is known that the SOC will make contact with the Command Center at 9:16 a.m., if not earlier (see 9:16 a.m.-9:18 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 9, 15] Bill Halleck, an air traffic control specialist at the SOC, is at least able to reach the FAA’s Boston Center regarding Flight 11 at 8:29 a.m. (see 8:29 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 5, 453] The four American Airlines managers will also tell the 9/11 Commission, “In the event that the [American Airlines] SOC was aware that it was the first to know about an incident [with an aircraft], the protocol would have been for the SOC manager on duty [i.e. Marquis] to have immediately autodialed to the Herndon manager on duty [i.e. Ben Sliney] with the information.” However, the FAA “knew what was going on because of the intercepted communications from the cockpit.” [9/11 Commission, 11/19/2003 pdf file] (FAA air traffic controllers have been aware of problems with Flight 11 since around 8:14 a.m., when they lost communication with the plane (see 8:14 a.m.-8:24 a.m. September 11, 2001), and they subsequently hear communications made by the hijackers on the plane, beginning at 8:24 a.m. (see 8:24 a.m. September 11, 2001).

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

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).

Bill Halleck, an air traffic control specialist at the American Airlines System Operations Control (SOC) center in Fort Worth, Texas, calls the FAA’s Boston Center to ask about the status of Flight 11 and is told that the plane has deviated from its flight path, air traffic controllers have lost communication with it and have lost its transponder signal, and they have heard a possible threat being made in the background over the radio. This call is American Airlines’ first contact with FAA controllers regarding Flight 11. [9/11 Commission, 3/25/2004, pp. 15; 9/11 Commission, 4/26/2004; 9/11 Commission, 4/26/2004 pdf file]
Manager Told Halleck to Call FAA - At 8:21 a.m., Craig Marquis, the manager on duty at the SOC, received a call from a supervisor at the American Airlines Southeastern Reservations Office in North Carolina, alerting him to a call the office had received from Betty Ong, a flight attendant on Flight 11, reporting the emergency on her plane (see 8:21 a.m. September 11, 2001). Marquis had replied that he would get in touch with air traffic control about this. [9/11 Commission, 8/26/2004, pp. 9] He asked Halleck to contact the FAA’s Boston Center and find out what is happening with Flight 11. Immediately after receiving this request, Halleck calls the traffic management unit (TMU) at the Boston Center. [9/11 Commission, 1/8/2004 pdf file; 9/11 Commission, 4/26/2004 pdf file]
Boston Center Tells Halleck Details of Crisis - When the call is answered, Halleck introduces himself and then says, “[W]e’re trying to find out the status to what you know about our Flight 11.” The Boston Center controller replies that Flight 11’s last reported altitude was below 29,000 feet. He reports that the flight has altered course, saying, “He was heading west, but right now he’s pointed southwest of Albany.” Furthermore, he says, “we lost frequency with him,” meaning communication has been lost with the plane, and adds that the plane’s transponder has been turned off.
Controller Heard a 'Threat in the Background' on Flight 11 - The controller at the TMU also tells Halleck that the Boston Center controller dealing with Flight 11 “heard on the frequency a threat in the background, but that’s unconfirmed and we’re trying to pull the tape [recording of the radio communication] at this time.” Halleck asks for clarification that the controller handling Flight 11 “heard a background noise in the cockpit,” and is told: “Like a threat. Yes, sir.” The controller at the TMU adds that he has been told that it is believed the pilot’s microphone on Flight 11 was keyed, and so the controller handling the flight “heard in the background, like, yeah, ‘Return to an airport… or I’ll kill you,’ or something to that effect.” He also says the plane is not squawking any emergency transponder codes. Halleck says he is tracking Flight 11 on the aircraft situation display, and the controller replies that the Boston Center is currently tracking the plane with primary radar only. The controller ends by telling Halleck, “That is all we have.” [American Airlines, 9/11/2001, pp. 56-57; American Airlines, 9/11/2001, pp. 58; 9/11 Commission, 1/8/2004 pdf file]
Halleck Does Not Pass On Information from Flight Attendant - With this call, Halleck is the first person at American Airlines to speak to FAA air traffic control personnel about Flight 11. [9/11 Commission, 4/26/2004; 9/11 Commission, 4/26/2004 pdf file] During the call, he does not tell the Boston Center controller about the ongoing conversation between American Airlines and Ong, or what Marquis has learned from this conversation. [United States District Court for the Southern District of New York, 1/16/2009 pdf file] Halleck will promptly pass on the information from the Boston Center to Marquis, and this will lead American Airlines to suspect that Flight 11 has been hijacked (see 8:33 a.m. September 11, 2001).

Gerard Arpey.Gerard Arpey. [Source: American Airlines]Gerard Arpey, American Airlines’ executive vice president of operations, learns of the trouble on Flight 11 and then heads to the airline’s System Operations Control (SOC) center, but he is unable to contact the airline’s president to alert him to the crisis at this time. [9/11 Commission, 1/8/2004 pdf file]
Arpey Told about Call from Flight Attendant - At around 8:30 a.m., Arpey, who is in his office at American Airlines’ headquarters in Fort Worth, Texas, makes a routine phone call to the nearby SOC. [9/11 Commission, 1/27/2004; 9/11 Commission, 8/26/2004, pp. 12] The call is answered by Joseph Bertapelle, the manager of SOC operations coordination/air traffic systems. [9/11 Commission, 1/8/2004 pdf file] Bertapelle tells Arpey about a phone call the airline has received from Betty Ong, a flight attendant on the hijacked Flight 11. [9/11 Commission, 1/27/2004; 9/11 Commission, 8/26/2004, pp. 12] Since 8:18 a.m., Ong has been on the phone with employees at the American Airlines Southeastern Reservations Office in North Carolina (see 8:18 a.m. September 11, 2001), and one of those employees has been relaying the information Ong provides to Craig Marquis, the manager on duty at the SOC (see (8:21 a.m.) September 11, 2001). [9/11 Commission, 11/19/2003 pdf file; 9/11 Commission, 8/26/2004, pp. 8-9]
Arpey Wonders if Ong's Call Is Genuine - Bertapelle tells Arpey that Marquis has learned that Ong said there were “bad guys” on her plane and a flight attendant had been stabbed. Arpey wonders if the call from Ong is genuine. Considering the number of “crank” calls the airline receives, he will later comment, he is “conditioned to be somewhat skeptical.” However, when Bertapelle says Ong has reported a cockpit intrusion (see 8:22 a.m.-8:24 a.m. September 11, 2001), this information makes Arpey think “that the incident could be the real thing.”
Arpey Unable to Reach Airline's President - Immediately after the call with Bertapelle ends, Arpey tries calling Don Carty, the president of American Airlines, to let him know what is happening. [9/11 Commission, 1/8/2004 pdf file; 9/11 Commission, 8/26/2004, pp. 12] But Carty is at home answering e-mails and so has not yet arrived at his office. Arpey therefore leaves a message, requesting that Carty call him as soon as possible.
Arpey Heads to Operations Center, Learns Details of Hijacking - Arpey briefs his executive assistant on what he has learned about the trouble on Flight 11. [Wall Street Journal, 10/15/2001; 9/11 Commission, 1/27/2004] He then heads to the SOC, along with Dan Huffman, American Airlines’ senior vice president of maintenance and engineering. [9/11 Commission, 1/8/2004 pdf file] The SOC is about a mile away from the airline’s headquarters, and Arpey will recall that he arrives there at between 8:35 a.m. and 8:40 a.m. After he reaches the SOC, managers there tell him they are now treating Flight 11 as a confirmed hijacking. Arpey is told that the plane’s pilots are still not responding to calls from the flight attendants and that Ong said a passenger in first class had been stabbed, possibly fatally (see 8:33 a.m. September 11, 2001). He learns that the FAA has notified the airline that, instead of heading west on its intended flight path, Flight 11 is heading south; the plane’s transponder has been turned off; and the pilots are not responding to radio calls (see 8:29 a.m. September 11, 2001). [9/11 Commission, 1/27/2004] Arpey also learns that airline managers are setting up the System Operations Command Center in order to deal with the emergency (see (Between 8:40 a.m. and 8:55 a.m.) September 11, 2001), and because they are doing this, he will say, he “knew that they had concluded the incident was real.” [9/11 Commission, 1/8/2004 pdf file; 9/11 Commission, 8/26/2004, pp. 12] As executive vice president of operations, Arpey is responsible for American Airlines’ worldwide flight operations, and he will therefore be directly involved in the airline’s subsequent emergency response efforts and other operational decisions throughout the day.

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

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

Flight controllers ask the United Airlines Flight 175 pilots to look for a lost American Airlines plane 10 miles to the south—a reference to Flight 11. They respond that they can see it. They are told to keep away from it. [Guardian, 10/17/2001; Boston Globe, 11/23/2001; 9/11 Commission, 6/17/2004] Apparently, Flight 175 is not told Flight 11 has been hijacked. Flight 175 itself is hijacked a few minutes later (see 8:41 a.m.-8:42 a.m. September 11, 2001).

Technicians at NORAD’s Northeast Air Defense Sector (NEADS) try frantically to locate Flight 11 on their radar scopes, but are supposedly hindered by their outdated equipment. [Spencer, 2008, pp. 31-32] NEADS has just been alerted to the hijacking of Flight 11 (see (8:37 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] Its technicians realize they need to find the location of the hijacked plane quickly, so that the weapons team will be able to pass this information on to any fighter jets that are launched after it.
Locating Flight 11 Is a 'Grueling Process' - Author Lynn Spencer will later explain: “To identify American 11, the surveillance and ID techs must go through a grueling process. Their radar scopes are filled with hundreds of radar returns not just from aircraft but from weather systems, ground interference, and what’s called anomalous propagation—false returns caused by conditions in the atmosphere, or by such obstructions as flocks of birds. The technicians must first determine which radar data on their screens is for aircraft, which they do by monitoring its movement, which is distinctive for planes. The technician must observe for at least 36 seconds to a minute just to confirm that a blip is in fact an aircraft track. The tech must attach what’s called a tactical display number to it, which tells the computer to start tracking and identifying the target. If the target is in fact a plane, then over a period of 12-20 seconds, the computer will start to generate information on the track: heading, speed, altitude, latitude, longitude, and the identifying information being transmitted by the transponder.” However, Flight 11’s transponder has been switched off (see (Between 8:13 a.m. and 8:21 a.m.) September 11, 2001). Therefore, “With the hundreds of pieces of radar data filling their screens, and little information as to the location of the flight,” the task of locating it “is daunting.”
Radar Equipment Supposedly Unsuitable - Spencer will suggest that trying to locate Flight 11 is made more difficult because the radar equipment at NEADS is outdated and unsuited to the task at hand. She writes: “[T]he NEADS radar equipment is different from that used by air traffic controllers. It’s much older, developed in the 1970s and brought into use by NEADS in the early 1980s. The system was designed to monitor the shoreline for incoming high-altitude threats: missiles coming from across the ocean. Slow and cumbersome, and not nearly as user friendly as more modern equipment, the NEADS monochromic radar displays are not designed to take internal FAA radar data or to identify radar tracks originating from inside the United States. The system offers little, if any, such low-level coverage over the country.” [Spencer, 2008, pp. 31-32] Several of the NEADS personnel will later complain of their inability to locate Flight 11 on their scopes (see Shortly After 8:37 a.m. September 11, 2001). But Master Sergeant Joe McCain, the mission crew commander technician at NEADS, believes he has located Flight 11 on the radar screen just before it crashes into the World Trade Center (see 8:45 a.m.-8:46 a.m. September 11, 2001).

Flight 175 passes from the airspace of the FAA’s Boston Center to the airspace of the New York Center, which is in Ronkonkoma, New York. [9/11 Commission, 8/26/2004, pp. 20] New York Center air traffic controller Dave Bottiglia takes over monitoring the flight from Boston Center controller John Hartling (see (8:34 a.m.) September 11, 2001). Flight 175 waits nearly 45 seconds to check in with Bottiglia. According to author Lynn Spencer, this is “rather long, and Bottiglia is just about to call the plane.” But then Captain Victor Saracini, the pilot of Flight 175, makes radio contact, saying, “New York, United 175 heavy.” [Gregor, 12/21/2001 pdf file; Spencer, 2008, pp. 36]

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

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

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

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

In the event of an order to scramble the unit’s two F-16s that are kept on “alert,” his job would be to man the battle cab and serve as the supervisor of flying (SOF), being responsible for getting any necessary information about the mission to the pilots. Borgstrom’s fiancée, Jen, calls him at the base and asks, “Did you hear that some airplane just ran into the World Trade Center?” [Spencer, 2008, pp. 116; Tampa Tribune, 6/8/2008] This is the first that Borgstrom has heard about the attack. [Longman, 2002, pp. 63] He replies, “Probably some idiot out sightseeing or someone trying to commit suicide in a Cessna 172,” but Jen tells him, “It’s a pretty big fire for a small airplane.”
Intelligence Officer Warns, 'Get Ready' - The chief enlisted manager then enters Borgstrom’s office and informs him that Darrin Anderson, the unit’s intelligence officer, is on the phone from the wing’s base in Fargo, “and needs to talk to you right away.” Borgstrom heads to the main reception desk and takes the call. After asking if Borgstrom is aware of what happened in New York, Anderson tells him, “[W]e think there might be more to this, so you guys get ready.” Borgstrom tells the chief enlisted manager about this call and then heads out toward the alert hangars.
Pilot Learns of Attack - Meanwhile, in one of the hangars, the crew chief goes upstairs with some information for Major Dean Eckmann, who is one of the pilots on alert duty. Eckmann is unaware of events in New York. When his crew chief informs him a plane has hit the WTC, he replies: “Poor, dumb sucker. I hope no one in the building got hurt.” Before Eckmann has a chance to switch on the television to check the news, a Klaxon horn sounds, indicating that the two alert pilots at Langley are to go to “battle stations.” [Longman, 2002, pp. 64; Spencer, 2008, pp. 116-117] According to the 9/11 Commission, this battle stations signal occurs at 9:09 a.m. (see (9:09 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 24] Eckmann, along with Borgstrom and another of the unit’s pilots, will take off in order to defend Washington, DC at 9:30 a.m. (see (9:25 a.m.-9:30 a.m.) September 11, 2001).

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

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

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

Mike McCormick.Mike McCormick. [Source: Associated Press]Mike McCormick, the head of the FAA’s New York Center, sees the coverage of the first World Trade Center attack on CNN. He assumes that Flight 175, which he is tracking on his radar screen, is also headed into the WTC. He will recall: “Probably one of the most difficult moments of my life was the 11 minutes from the point I watched that aircraft, when we first lost communications until the point that aircraft hit the World Trade Center. For those 11 minutes, I knew, we knew, what was going to happen, and that was difficult.” [CNN, 8/12/2002] Yet, according to the 9/11 Commission, the New York Center will not notify NORAD’s Northeast Air Defense Sector (NEADS) about Flight 175 until around the time it crashes, at 9:03 a.m. (see (9:03 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). Flight 11 crashed into the World Trade Center seven minutes ago (see 8:46 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 7, 19 and 459]
Commander Wants Fighters Sent to New York - In Rome, New York, NEADS has just received news of the plane hitting the WTC (see 8:51 a.m. September 11, 2001). Major Kevin Nasypany, the facility’s mission crew commander, is asked what to do with the Otis fighters. He responds: “Send ‘em to New York City still. Continue! Go! This is what I got. Possible news that a 737 just hit the World Trade Center. This is a real-world.… Continue taking the fighters down to the New York City area, JFK [International Airport] area, if you can. Make sure that the FAA clears it—your route all the way through.… Let’s press with this.” [Vanity Fair, 8/1/2006] Yet there will be conflicting reports of the fighters’ destination (see (8:53 a.m.-9:05 a.m.) September 11, 2001), with some accounts saying they are directed toward military-controlled airspace off the Long Island coast.

However, even though the controller managing Flight 175 said, “we may have a hijack” at 8:53 a.m. (see 8:51 a.m.-8:53 a.m. September 11, 2001), the 9/11 Commission will conclude that NORAD’s Northeast Air Defense Sector (NEADS) is not notified about the aircraft until 9:03 a.m. (see (9:03 a.m.) September 11, 2001).

Flight 77’s transponder is turned off, meaning that the aircraft’s speed, altitude, and flight information are no longer visible on radar displays at the FAA’s Indianapolis Center. [Federal Aviation Administration, 9/17/2001 pdf file; National Transportation Safety Board, 2/19/2002 pdf file; 9/11 Commission, 7/24/2004, pp. 9] The Indianapolis Center air traffic controller in charge of Flight 77 watched the plane go off course and head southwest before its data disappeared from his radar screen. He looks for primary radar signals along the aircraft’s projected flight path as well as in the airspace where it had started to turn, but cannot find it. [9/11 Commission, 6/17/2004] He tries contacting the plane repeatedly, saying “American 77, Indy,” and: “American 77, Indy, radio check. How do you read?” But there is no response. [New York Times, 10/16/2001; New York Times, 10/16/2001]
NEADS Not Contacted - US News and World Report will later comment, “[E]xperts say that an airliner making a 180-degree turn followed by a transponder turnoff should have been a red flag to controllers.” It will quote Robert Cauble, a 20-year veteran of Navy air traffic control, who says: “The fact that the transponder went off, they should have picked up on that immediately. Everyone should have been on alert about what was going on.” [US News and World Report, 10/8/2001] Yet the Indianapolis Center supposedly does not notify NORAD’s Northeast Air Defense Sector (NEADS). According to the 9/11 Commission, NEADS will only learn that Flight 77 is missing at 9:34 a.m. (see 9:34 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 26-27]
Controller Thinks Plane Suffered Mechanical Failure - While several air traffic control centers were reportedly informed of the Flight 11 hijacking as early as 8:25 a.m. (see 8:25 a.m. September 11, 2001), according to the 9/11 Commission, the controller handling Flight 77 does not realize other aircraft have been hijacked, and he is unaware of the situation in New York. He mistakenly assumes Flight 77 has experienced an electrical or mechanical failure. [Guardian, 10/17/2001; 9/11 Commission, 6/17/2004] After he informs other Indianapolis Center personnel of the developing situation, they will clear all other aircraft from the plane’s westerly route so their safety will not be affected if Flight 77 is still flying along its original path but unable to be heard.

But controller Jim Bohleber says, “No, he’s too fast and low, he’ll never make Newark.” [Newsday, 9/10/2002] The controllers start speculating what Flight 175 is aiming for, with one of them guessing the Statue of Liberty. [Vanity Fair, 8/1/2006] They are astonished at the extraordinary rate at which it is descending (see (8:58 a.m.-9:03 a.m.) September 11, 2001).

Air traffic controllers at the FAA’s New York Center who are watching Flight 175 on the radar screen (see (8:57 a.m.-9:03 a.m.) September 11, 2001) see the aircraft descending at an astonishing rate of up to 10,000 feet per minute. [The Learning Channel, 8/20/2006] From 8:58 a.m., Flight 175 is constantly descending toward New York. [National Transportation Safety Board, 2/19/2002 pdf file] One of the New York Center controllers, Jim Bohleber, is looking at his radar scope and calls out the plane’s rate of descent every 12 seconds, each time the screen updates, saying: “It’s six thousand feet a minute. Now it’s eight. Now ten.” [Newsday, 9/10/2002; Vanity Fair, 8/1/2006] Dave Bottiglia, the controller responsible for monitoring Flight 175, will later comment that 10,000 feet per minute is “absolutely unheard of for a commercial jet. It is unbelievable for the passengers in the back to withstand that type of force as they’re descending. [The hijackers are] actually nosing the airplane down and doing what I would call a ‘power dive.’” [The Learning Channel, 8/20/2006] While Flight 175 is in this rapid descent, it heads directly into the paths of several other aircraft, and narrowly avoids a mid-air collision with flight Midex 7 (see (9:01 a.m.) September 11, 2001).

[9/11 Commission, 7/24/2004, pp. 7-8] When the supervisor tells Miles about this, he initially responds, “No, the information we’re getting is that it was an American 757.” (The FAA has just informed United Airlines that the plane that hit the World Trade Center was a hijacked American Airlines 757 (see (Shortly After 8:48 a.m.) September 11, 2001).) But the supervisor insists, “No, we got a call from a flight attendant on 175.” [Wall Street Journal, 10/15/2001] Miles notifies his boss Bill Roy, the SOC director, about this information.

In an apparent reference to the hijacking on a phone bridge with other air traffic control facilities, Mulligan first says the situation is escalating (see (9:01 a.m.) September 11, 2001) and adds, “Just get me somebody who has the authority to get military in the air now.” Mulligan then drops out of the teleconference for a short while, but returns and says: “It’s OK. I’ve got it taken care of over here. I got… my military guy. We got some interceptors in the air.” [Federal Aviation Administration, 10/14/2003, pp. 15-17 pdf file] According to the 9/11 Commission Report, Mulligan says this between 9:01 and 9:02.

Moments before Flight 175 crashes into the World Trade Center, Colin Scoggins, the military liaison at the FAA’s Boston Center, calls NORAD’s Northeast Air Defense Sector (NEADS) to notify it that there is a second hijacked aircraft over the US. Scoggins learned of the second hijacking on the FAA headquarters’ hijack teleconference (see (Shortly Before 9:02 a.m.) September 11, 2001) and senses that he should call NEADS with this latest information. According to author Lynn Spencer, Scoggins “imagines that he must be one of dozens of FAA facilities flooding [NEADS] with phone calls. What he doesn’t know is that his is in fact the only one giving them information about the flights this morning, other than the coverage on CNN.” [Spencer, 2008, pp. 82] However, the 9/11 Commission will say that NEADS also learns of the second hijacking around this time from the FAA’s New York Center, stating, “The first indication that the NORAD air defenders had of the second hijacked aircraft, United 175, came in a phone call from New York Center to NEADS at 9:03” (see (9:03 a.m.) September 11, 2001).

[North American Aerospace Defense Command, 9/18/2001] Additionally, as Flight 175 crashes into the WTC, Canadian Captain Mike Jellinek, who is working at NORAD’s Cheyenne Mountain, Colorado operations center, is on the phone with NEADS. He sees the crash live on television and asks NEADS, “Was that the hijacked aircraft you were dealing with?” The reply is yes. (However, it is unclear whether Jellinek is referring to Flight 175 or to the smoke coming from the crash of Flight 11.) [Toronto Star, 12/9/2001] If the 9/11 Commission’s account is correct, several questions remain unanswered. Flight 175 lost radio contact at 8:42 a.m. (see 8:41 a.m.-8:42 a.m. September 11, 2001) and changed transponder signals at 8:47 a.m. (see 8:46 a.m.-8:47 a.m. September 11, 2001); an air traffic controller declared it possibly hijacked sometime between 8:46 a.m. and 8:53 a.m. (see (Shortly After 8:46 a.m.) September 11, 2001); and an air traffic control manager called it hijacked at 8:55 a.m.(see (8:55 a.m.) September 11, 2001). The Commission will not explain why the New York Center waits 10 to 16 minutes before warning NEADS that Flight 175 is possibly hijacked. [9/11 Commission, 6/17/2004]

NORAD’s Northeast Air Defense Sector (NEADS) in Rome, NY, has just received a phone call informing it of the hijacking of Flight 175 (see (9:03 a.m.) September 11, 2001), and several personnel have witnessed the plane crashing into the second World Trade Center tower live on CNN. There is considerable confusion on the operations floor over whether the plane seen on TV is the hijacking they have just been informed of. Tape recordings capture NEADS personnel in the background trying to make sense of things: “Is this explosion part of that that we’re lookin’ at now on TV?“… “And there’s a possible second hijack also—a United Airlines“… “Two planes?” Someone comments, “I think this is a damn input, to be honest.” [Vanity Fair, 8/1/2006] Another person replies, “Then this is a damned messed-up input!” [Spencer, 2008, pp. 84] “Input” refers to a simulations input, as part of a training exercise. [Vanity Fair, 8/1/2006] NORAD has the capacity to inject simulated material, including mass attacks, during exercises, “as though it was being sensed for the first time by a radar site.” [US Department of Defense, 1/15/1999] At least one military exercise this morning is reported to include simulated information injected onto radar screens (see (9:00 a.m.) September 11, 2001). [Toronto Star, 12/9/2001] At the current time, despite the earlier crash of Flight 11, NORAD has yet to cancel a major exercise it is in the middle of (see (Shortly After 9:03 a.m.) September 11, 2001).

Logo of the 552nd Air Control Wing.Logo of the 552nd Air Control Wing. [Source: US Air Force]An Airborne Warning and Control System (AWACS) plane on a training mission in the Washington, DC, area is instructed to return to its base in Oklahoma, even though its advanced communications and surveillance capabilities would significantly benefit the military’s air defense efforts in response to the terrorist attacks. The AWACS belongs to the 552nd Air Control Wing, located at Tinker Air Force Base in Oklahoma. [US Air Force, 4/1/2000; GlobalSecurity (.org), 4/16/2006; Spencer, 2008, pp. 265] It has been flying a training mission somewhere near Washington (see Before 9:55 a.m. September 11, 2001). [Code One Magazine, 1/2002]
AWACS Sent Back to Oklahoma - According to author Lynn Spencer, the AWACS is directed to return to Tinker Air Force Base “in the immediate confusion after the attacks.” The exact time the plane’s crew receives this order, and the identity of the person or organization that gives the order, are unstated. NORAD’s Northeast Air Defense Sector (NEADS) will contact the AWACS later on, and instruct it to turn around and head to Washington, to provide radio and radar coverage over the capital (see (11:25 a.m.) September 11, 2001). [Spencer, 2008, pp. 265-266]
AWACS Has Advanced Surveillance and Communication Capabilities - The AWACS, also called the E-3 Sentry, is a modified Boeing 707 that provides surveillance, command, control, and communications to military commanders. [New York Times, 9/23/1995; GlobalSecurity (.org), 4/16/2006; US Air Force, 9/22/2015] According to a US Air Force manual, the plane’s “advanced surveillance radar provides long-range, low-level detection of aircraft targets over all types of terrain.” [US Air Force, 4/1/2000] It can track friendly and enemy aircraft over a 300-mile radius. [New York Times, 9/23/1995] Mark Rosenker, the director of the White House Military Office, will say that AWACS planes “give you the big picture in the sky. They’re able to identify what’s a friend, what’s a foe.” [White House, 8/29/2002]
AWACS Would Help NEADS Contact Fighters - These planes are particularly important to NEADS. [9/11 Commission, 10/30/2003 pdf file] Spencer will describe: “The NEADS radio transmitter, like all radio transmitters, operates by line of sight. This means that the radio signals, which travel in a straight line, require an unobstructed path between the transmitter and the [fighter] jets” that NEADS is trying to communicate with this morning. Due to the curvature of the earth and the distance between NEADS, in Rome, New York, and Washington, the fighters’ launched to protect the capital (see 9:24 a.m. September 11, 2001 and (9:50 a.m.) September 11, 2001) will be unable to pick up the NEADS signal on their radio receivers when they descend below 20,000 feet, after arriving over Washington (see (Between 9:49 a.m. and 11:00 a.m.) September 11, 2001 and (11:25 a.m.) September 11, 2001). “What’s needed,” Spencer will write, “is an AWACS plane, which has the capability to provide both radar and radio coverage over a citywide area.” [Spencer, 2008, pp. 265]

Gary Walters.Gary Walters. [Source: C-SPAN]Gary Walters, the chief White House usher, and a few of his colleagues take the time to clear up the White House grounds ready for when President Bush returns, and even continue with the task after the White House is evacuated. Earlier this morning, many White House staffers were busy preparing for the annual Congressional picnic, which was scheduled to take place this evening (see 8:30 a.m. September 11, 2001). About 170 to 180 picnic tables have been set up on the South Lawn for the event. After he learns that a second plane has crashed into the World Trade Center (see 9:03 a.m. September 11, 2001), Walters decides to start moving the picnic tables off the lawn so Bush’s helicopter will be able to land on the grounds when the president returns to the White House. [National Journal, 8/31/2002; Values in World Thought, 4/4/2006; Peter Schnall, 7/12/2016]
Usher Arranges to Clear the Lawn - He coordinates with the National Park Service, which is in charge of the White House grounds, to determine who will be clearing away the picnic tables. [Brower, 2015, pp. 257] He then sets about moving the tables. “I got the staff together and started sending them out to the south grounds—anybody I could think of—because I knew that we had to try to move as quickly as possible,” he will later recall. [National Journal, 8/31/2002] However, at about 9:45 a.m., the White House is evacuated after the Secret Service learns of a possible threat against it (see (9:45 a.m.) September 11, 2001). [Associated Press, 2001 pdf file; CNN, 9/12/2001]
Staffers Continue Clearing the Grounds, despite the Danger - Around this time, Walters sees the smoke coming from the Pentagon, which was attacked at 9:37 a.m. (see 9:37 a.m. September 11, 2001), and realizes the White House could be hit next. And yet he decides that he needs to stay where he is in order to clear up the grounds. “As far as I was concerned, my responsibility was there at the White House,” he will comment. [Brower, 2015, pp. 258] “I knew we had to get those tables out,” he will state, adding, “I even felt more urgency, since obviously this was a coordinated attack now.” [National Journal, 8/31/2002] While the Secret Service is ordering people to run for their lives, Walters grabs a few of his colleagues and tells them they need to stay and help clear away the picnic tables. “I got the word that everybody was evacuating, but we had something that we needed to do,” he will comment. [Brower, 2015, pp. 258] After hearing that another suspicious plane is approaching, however, Walters and his colleagues go to the southeast knoll, a rise in the White House lawn, and just stand there, watching the sky and waiting.
Lawn Is Cleared by Early Afternoon - By around 11:00 a.m., they are becoming impatient. Walters therefore says, “Guys, let’s go move some picnic tables.” The men then start carrying the picnic tables off the lawn. A police officer joins them and eventually about a dozen people are helping them to move the tables. By around 1:00 p.m. all of the tables have been removed from the lawn. At about 3:45 p.m., Walters is called by someone from the military, who asks him to clear the South Lawn so the president’s helicopter will be able to land there. Walters laughs and says this has already been done. [National Journal, 8/31/2002] The president’s helicopter, with Bush on board, will land on the South Lawn at around 6:55 p.m. (see (6:54 p.m.) September 11, 2001). [CNN, 9/12/2001; Rove, 2010, pp. 263]
Usher Will Later Justify His Actions - Walters will, in 2016, explain why he made the effort to clear up the White House grounds, despite the danger to himself and his colleagues. “One of the things that I turned to in my own mind on 9/11 was the role that the White House plays in disasters, wars,” he will say, adding, “People have a tendency to turn to the White House.” He will continue: “And I knew that the president wasn’t gonna be satisfied talking from a bunker somewhere or away from the White House. And that’s why we put the effort that we did into cleaning up the south grounds, so that [his] helicopter could land there. That was what the American people were used to seeing—the presidential helicopter coming in—and the president was going to address the nation from the Oval Office.” [Peter Schnall, 7/12/2016]

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

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

Major Kevin Nasypany, the mission crew commander at NORAD’s Northeast Air Defense Sector (NEADS), instructs a colleague of his to send a tanker plane from McGuire Air Force Base in New Jersey into military training airspace over the Atlantic Ocean. Ten minutes ago, NEADS contacted McGuire Air Force Base and asked if it had any tankers available to support the fighter jets that took off from Otis Air National Guard Base in response to the hijacking of Flight 11. An officer at McGuire said the base had two KC-10 tankers airborne and these planes were carrying plenty of fuel (see 9:04 a.m. September 11, 2001).
Staffer Is Told to Send a Tanker into Training Airspace - A member of staff at NEADS now discusses what to do with these tankers with Nasypany. “We’ve got McGuire offering two more tankers if we need them,” he says. Nasypany says in response, “Okay” and then instructs, “Get me that KC-10, stick him in 107.” [North American Aerospace Defense Command, 9/11/2001; North American Aerospace Defense Command, 9/11/2001] “107” is “Whiskey 107,” an area over the Atlantic Ocean, about 70 miles east of Atlantic City, New Jersey, that is frequently used for military training. [CNN, 2/7/1997; New York Times, 2/7/1997; Global Security (.org), 5/7/2011] The staffer asks Nasypany if he wants to send one or both of the tankers into Whiskey 107. Nasypany replies, “One” and adds: “Two KC-10s should do it fine. Put him in 107.”
Both Tankers Are Apparently Sent over the Ocean - Nasypany then tells another person about the tankers and what he intends to do with them. “I got two offers up from McGuire for KC-10s,” he says, adding, “I’m taking one KC-10, putting him in Whiskey 107, gonna hold him there for the Langley guys.” [North American Aerospace Defense Command, 9/11/2001; North American Aerospace Defense Command, 9/11/2001] The “Langley guys” are the F-16 fighters at Langley Air Force Base in Virginia that have been put on “battle stations” (see (9:09 a.m.) September 11, 2001) and will be scrambled at 9:24 a.m. (see 9:24 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 24, 27] Despite what Nasypany has said, both—not just one—of the KC-10s from McGuire Air Force Base will apparently be directed into Whiskey 107. At 9:25 a.m., Nasypany will tell a colleague he has “two KC-10s” out of McGuire and he is “sticking them in Whiskey 107.” [North American Aerospace Defense Command, 9/11/2001; North American Aerospace Defense Command, 9/11/2001]

[Source: Discovery Channel]At “approximately 9:15 a.m.,” according to the 9/11 Commission, Daniel Bueno, a supervisor at the FAA’s Boston Center, asks the FAA’s Herndon Command Center to contact all the FAA centers nationwide and instruct them to issue an alert, informing all airborne aircraft of the events unfolding in New York and advising them to heighten their cockpit security. Boston Center air traffic controllers have recently issued a similar alert to all aircraft in their airspace (see 9:09 a.m.-9:10 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 25-26] However, the 9/11 Commission will conclude, “We have found no evidence to suggest that the Command Center acted on this request or issued any type of cockpit security alert.” [9/11 Commission, 7/24/2004, pp. 23] According to author Lynn Spencer, “The request never makes it to Ben Sliney,” the national operations manager at the Command Center. “Tragically, it is lost in the confusion and never gets past the staff person monitoring Sliney’s desk as events rapidly spiral out of control.” [Spencer, 2008, pp. 99] But Ellen King, a Command Center manager, offers a different explanation. She will tell the 9/11 Commission that the FAA culture and mindset on 9/11 are such that the FAA “would never have relayed this message directly to all pilots.… [T]he FAA would pass situational awareness to the airline company representatives who, in turn, would determine if such action was necessary.” [9/11 Commission, 8/26/2004, pp. 26 and 92]

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

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

[Source: United Airlines]Just before 9:22, United Airlines headquarters, located outside Chicago, begins the “lockout” procedure to restrict access to passenger and crew information about Flight 175. [9/11 Commission, 8/26/2004, pp. 26] This procedure is standard for airlines in safety and security incidents. As the 9/11 Commission will later describe, “It acknowledges an emergency on the flight and isolates information so that the case can be managed by top leadership at the airlines in a way that protects information from being altered or released, and also protects the identities of the passengers and crew.” [9/11 Commission, 8/26/2004, pp. 12-13] This procedure begins almost 40 minutes after Flight 175 was hijacked (see (Between 8:42 a.m. and 8:46 a.m.) September 11, 2001), and about 35 minutes after the plane’s transponder signal changed (see 8:46 a.m.-8:47 a.m. September 11, 2001).

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

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

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

Flight 93 makes its last normal communication with air traffic control before being hijacked, acknowledging a routine radio transmission from the FAA’s Cleveland Center. [9/11 Commission, 7/24/2004, pp. 28] Flight 93 checked in with the Cleveland Center a couple of minutes earlier (see 9:24 a.m.-9:25 a.m. September 11, 2001). At 9:27, the Cleveland controller, John Werth, alerts it to another aircraft 12 miles away and to its right, at 37,000 feet: “United 93, that traffic for you is one o’clock, 12 miles east, bound three-seven-zero.” Seconds later, Flight 93 responds, “Negative contact, we’re looking, United 93.” Less than a minute after this, the hijackers appear to enter Flight 93’s cockpit (see (9:28 a.m.) September 11, 2001).

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

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

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).

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

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

The Fleet Area Control and Surveillance Facility in Virginia Beach, Virginia, takes control of the three F-16 fighter jets launched from Langley Air Force Base (see (9:25 a.m.-9:30 a.m.) September 11, 2001), even though, according to air traffic controllers at the facility, it should not be communicating with the fighters. [9/11 Commission, 12/3/2003 pdf file; 9/11 Commission, 12/3/2003 pdf file; 9/11 Commission, 2004; 9/11 Commission, 1/9/2004] The Fleet Area Control and Surveillance Facility, known as “Giant Killer,” is the Navy air traffic control agency that handles all over-water military operations. [Spencer, 2008, pp. 143; US Navy, 2/11/2016] The flight plan for the Langley F-16s puts the fighters into its airspace (see (9:30 a.m.) September 11, 2001). [9/11 Commission, 12/3/2003 pdf file] The facility consequently takes over control of the aircraft from the FAA’s Norfolk Terminal Radar Approach Control (TRACON) (see 9:31 a.m.-9:33 a.m. September 11, 2001). [9/11 Commission, 2004; 9/11 Commission, 1/9/2004]
Fighters Shouldn't Be Switched to the Facility's Frequency, Controller Will Say - However, according to Senior Chief Petty Officer Darren Clipper, an air traffic controller at the facility, the Norfolk TRACON “should not have switched the flight to Giant Killer frequency, plain and simple.” “Giant Killer should not have been talking to the fighters,” Clipper will state. He will tell the 9/11 Commission that Giant Killer is “not expected to be [one of the] participants in active air scrambles.” If NORAD’s Northeast Air Defense Sector (NEADS) scrambles fighters, he will say, the “onus is on the fighters and NEADS to go where they want to go,” and “it is Giant Killer’s responsibility to stay out of the way.” Based on the scramble order for the Langley fighters (see 9:24 a.m. September 11, 2001), Clipper will say, the FAA’s Washington Center and the Norfolk TRACON “should have made sure there was a clear path for the fighters to go direct” to the control of NEADS. [9/11 Commission, 12/3/2003 pdf file]
Other Controllers Say the Facility Does Not Handle Scrambled Jets - Petty Officer Matthew Barcus, another controller at Giant Killer, will say a similar thing to what Clipper does. “Most of the time, Giant Killer does not talk to the scrambled aircraft,” he will tell the 9/11 Commission. He will say that a scrambled flight “is usually handed off to [NEADS] by Norfolk” TRACON or the FAA’s Washington Center. [9/11 Commission, 12/3/2003 pdf file] And Lieutenant Commander Mary Klug, the operations officer at the facility, will tell the 9/11 Commission that Giant Killer does “not normally control scrambled aircraft.” [9/11 Commission, 12/3/2003 pdf file] However, author Lynn Spencer will apparently contradict Clipper, Barcus, and Klug, writing, “Protocol dictates that Giant Killer direct the jets until they reach Washington Center’s airspace, where the FAA controllers take over.” [Spencer, 2008, pp. 149]
Pilot Has Poor Experiences of Dealing with the Facility - Major Brad Derrig, the pilot of one of the fighters scrambled from Langley Air Force Base, will tell the 9/11 Commission that his experience with Giant Killer is that the facility is “not very good.” Sometimes, he will say, when Langley fighters have contacted Giant Killer, controllers at the facility “didn’t know who the air defense fighters were.” [9/11 Commission, 12/1/2003]

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.

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

Colin Scoggins, the military liaison at the FAA’s Boston Center, calls NORAD’s Northeast Air Defense Sector (NEADS) to report a low-flying airliner he has spotted six miles southeast of the White House. He can offer no details regarding its identity. The plane is reportedly Flight 77, but as it has its transponder turned off, no one realizes this at the time. The news of the plane “sets off a frenzy.” Major Kevin Nasypany orders Major James Fox, head of the NEADS weapons team, “Get your fighters there as soon as possible!” Staff Sergeant William Huckabone says, “Ma’am, we are going AFIO [emergency military control of the fighters] right now with Quit 2-5 [the Langley Air Force Base fighters]” (see 9:36 a.m. September 11, 2001), and adds, “They are going direct Washington.” [Vanity Fair, 8/1/2006] The Langley fighters will arrive over Washington some time around 10 a.m. (see (Between 9:49 a.m. and 11:00 a.m.) September 11, 2001).

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

James Roche.James Roche. [Source: United States Air Force]General John Jumper, the Air Force chief of staff, and James Roche, the secretary of the Air Force, head to the Air Force Operations Center in the basement of the Pentagon, where they will assist the Air Force’s response to the terrorist attacks. [CNN, 10/10/2001; Air Force Print News, 9/11/2003; Air Force Magazine, 9/2011 pdf file] Roche learned about the attacks on the World Trade Center while he was holding a breakfast meeting with several members of Congress in his office on the fourth floor of the Pentagon. He then arranged for the members of Congress to return to their offices, but stayed in his own office (see (Shortly After 8:48 a.m.) September 11, 2001). [Air Force Magazine, 9/2011 pdf file] Jumper learned about the attacks during a staff meeting he was chairing, but initially continued the meeting (see (9:00 a.m.-9:20 a.m.) September 11, 2001). [Goldberg et al., 2007, pp. 136] He adjourned it at 9:20 a.m., according to the Daytona Beach News-Journal. [Daytona Beach News-Journal, 9/7/2004 pdf file] He then headed up to Roche’s office. [Airman, 9/15/2011]
Roche and Jumper Possibly Unaware of Plane Approaching Washington - In the office now with Roche and Jumper are Colonel Philip Breedlove, Roche’s senior military assistant, and Colonel Jack Egginton, executive officer to the Air Force chief of staff. [Air Force Magazine, 9/2011 pdf file] It is unclear whether the men in Roche’s office realized a suspicious aircraft was approaching Washington, DC, before the Pentagon was hit, at 9:37 a.m. (see 9:37 a.m. September 11, 2001). Lieutenant General Lance Lord, assistant vice chief of staff of the Air Force, will later say that those who attended Jumper’s staff meeting “heard there was another plane inbound to Washington” as they were heading to their offices after the meeting. [Air Force Space Command News Service, 9/5/2002] And Egginton will say that a few minutes before the Pentagon was hit, “We received word that another aircraft was headed toward Washington.” [Air Force Print News, 9/11/2003] But according to the Midland Reporter-Telegram, Jumper’s staff had “no idea that they [i.e. the Pentagon] would be the next target for terrorists.” [Midland Reporter-Telegram, 4/2/2002]
Roche and Jumper Possibly Initially Unaware that the Pentagon Had Been Attacked - Breedlove will recall that shortly before the Pentagon was hit, while Roche and Jumper had their backs to the window, he and Egginton “saw an airplane go by really close to the building.” People who work at the Pentagon or visit it regularly are used to seeing planes flying by, near the building. “But that one seemed closer than any other,” Breedlove will comment. [Air Force Magazine, 9/2011 pdf file] However, it is unclear whether the men in Roche’s office immediately realized the Pentagon had been attacked when it was hit. The office is on the opposite side of the building to where the attack occurred and so, according to some accounts, Roche and Jumper did not feel the impact. They only realized something was wrong when they saw “people running down the halls and trying to evacuate the premises,” according to the Midland Reporter-Telegram. Roche will say that all he initially knew was that “the building was putting out the alert that something had gone wrong.” “It was amazing, from inside the building, how little we knew about what actually went on,” Tim Green, assistant executive to the Air Force chief of staff, who is with Jumper, will comment. “People outside of the building… probably knew more about what happened from the news than I did.” [CNN, 10/10/2001; Midland Reporter-Telegram, 4/2/2002] Egginton and Breedlove, however, will contradict these accounts. “I felt the building shake upon impact,” Egginton will say. Breedlove will recall, “We felt a tremor in the building and then alarms start flashing.”
Roche and Jumper Taken to Operations Center - Breedlove will say that, in response to the attack on the Pentagon, he promptly arranges for Jumper and Roche to be escorted to the Air Force Operations Center, in the basement of the Pentagon’s C Ring. He will recall that he hits the “duress button” and then security officers enter Roche’s office almost immediately. “We said, ‘We need to get to the bunker; we need to get down to our operations area,’” he will say. [Air Force Print News, 9/11/2003; Air Force Magazine, 9/2011 pdf file] Roche, though, will give a different account. He will say that his office had been “on the phone to our Operations Center” and then “we were called down,” presumably by whoever they were talking to in the Operations Center. [CNN, 10/10/2001] Roche and Jumper are escorted to the Operations Center through “smoke, alarms, and throngs of people heading for the exits,” Egginton will recall. [Air Force Print News, 9/11/2003]
Roche and Jumper Learn a Plane Hit the Pentagon - In the Operations Center, members of the Air Force Crisis Action Team have already begun to assemble so as to help provide assistance to civil authorities in New York (see (9:00 a.m.) September 11, 2001). [Goldberg et al., 2007, pp. 136] When Roche and Jumper reach the center, they will learn that the Pentagon has been hit by an aircraft (see After 9:37 a.m. September 11, 2001). [CNN, 10/10/2001] Other Air Force officials, including Lord, also head to the Operations Center after the Pentagon is hit. [Lompoc Record, 9/11/2003]

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

The transponder signal from Flight 93 ceases. [CNN, 9/17/2001; MSNBC, 9/3/2002; MSNBC, 9/11/2002; 9/11 Commission, 6/17/2004] However, the plane can be—and is—tracked using primary radar by Cleveland flight controllers and at United headquarters. Altitude can no longer be determined, except by visual sightings from other aircraft. The plane’s speed begins to vary wildly, fluctuating between 600 and 400 mph before eventually settling around 400 mph. [Longman, 2002, pp. 77, 214; 9/11 Commission, 6/17/2004]

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

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). NEADS will also order Air National Guard jets from Selfridge and Toledo to intercept Delta 1989 (see (9:55 a.m.) September 11, 2001 and 10:01 a.m. September 11, 2001).

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

The White House mess.The White House mess. [Source: Unknown]People at the White House are ordered to go to the “mess,” the senior staff dining room. David Kuo, a special assistant to the president, and John Bridgeland, the director of the White House Domestic Policy Council, will later recall being ordered to go downstairs to the mess by armed Secret Service agents. Meanwhile, Anita McBride, the acting director of White House personnel, is instructed by members of the Secret Service to “go through West Wing offices and tell everyone to ‘get out’ and stay put” in the mess. [Kuo, 2006, pp. 185; Politico, 9/9/2011; Bridgeland, 2012, pp. 3] Mary Matalin, a counselor to Vice President Dick Cheney, will recall, “Everyone still remaining in the West Wing was shepherded to the White House mess, where we were to await further instructions.” [Carville and Matalin, 2014, pp. 138]
Mess Is a 'Tiny, Unsecure' Facility - The White House mess is an exclusive dining facility run by the US Navy, located in the basement of the West Wing, just under the Oval Office. [All Hands, 12/1/2001; National Review, 10/8/2013] Bridgeland will recall thinking “how odd it was” for White House staffers to all be evacuated to this “tiny, unsecure” facility. [Bridgeland, 2012, pp. 4] People in the mess are watching television or just waiting.

Fifty people stood there, shocked, quiet, confused.” [Kuo, 2006, pp. 185]
People Ordered to the Mess after the Pentagon Attack - The exact time at which staffers are ordered to go to the mess is unclear. Matalin will recall being told to go there “moments” after she sees Cheney being evacuated from his office, which would be some time shortly after 9:36 a.m. (see (9:36 a.m.) September 11, 2001).

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

Engine Company 16.Engine Company 16. [Source: District of Columbia Fire and Emergency Medical Services Department]The District of Columbia Fire Department (DCFD) sends engines to the White House after the Secret Service incorrectly reports that a plane has crashed into the presidential residence and the building is on fire. As well as reporting the supposed plane crash and fire, the Secret Service says the White House, or at least part of it (the specific details are unclear), has collapsed. In response to the report, the fire communications center dispatches a “box alarm” from Engine Company 16, the station that serves the White House. [Washington City Paper, 9/21/2001; Journal of Emergency Medical Services, 4/2002 pdf file; Firehouse Magazine, 10/31/2002] A box alarm consists of four engines, two trucks, a rescue company, and a battalion chief. [Journal of Emergency Medical Services, 4/2002 pdf file] Since the alleged incident is at the White House—the home of the US president—the response is increased by sending an additional battalion chief and the deputy fire chief, Rogers Massey, to deal with it. And because a building collapse has been reported, the DCFD’s cave-in task force, which comprises Rescue 3, Battalion Chief 3, Engine 15, and the hazmat (hazardous materials) task force, is also sent. However, when the crews arrive at the White House, they are promptly told to leave. A uniformed Secret Service officer waves them away and says: “Get the f_ck outta here! There’s a plane coming in!” Lieutenant Jeff Wright, one of the firefighters involved in the response, will later recall the turn of events, saying: “It was mass confusion. We go down to the White House and no one knows what’s going on. We could see smoke coming from Virginia [where the Pentagon is located].” The report of the incident at the White House is investigated and determined to be unfounded. However, after he receives intelligence reports from the FBI, Special Operations Battalion Chief Michael Sellitto decides he will keep his units near the White House in case attacks should subsequently occur there or at the Capitol building. [Washington City Paper, 9/21/2001; Journal of Emergency Medical Services, 4/2002 pdf file; Firehouse Magazine, 10/31/2002] The DCFD will also respond to the attack on the Pentagon, which occurred at 9:37 a.m. (see 9:37 a.m. September 11, 2001). It will dispatch a box alarm to the Department of Defense’s headquarters at around 9:48 a.m. [DCFD (.com), 9/12/2001; Washington City Paper, 9/21/2001; Goldberg et al., 2007, pp. 72]

NORAD fails to notify the Pentagon’s air threat conference call that its fighter jets have set up a combat air patrol (CAP) over Washington, DC, until at least 50 minutes after the CAP has been established. [US Department of Defense, 9/11/2001 pdf file; US Department of Defense, 9/11/2001; 9/11 Commission, 6/9/2004] The National Military Command Center (NMCC) at the Pentagon commenced an air threat conference call at 9:37 a.m. in response to the terrorist attacks (see 9:37 a.m.-9:39 a.m. September 11, 2001). A NORAD representative has been on the conference from the outset. [9/11 Commission, 7/24/2004, pp. 37-38] However, an after-action report produced by the NMCC will state that NORAD is “unable to provide accurate updates on [the] CAP status in [the] air threat conference.” It takes “50 minutes from the time the CAP [is] established overhead DC for NORAD to report it in the conference.” [9/11 Commission, 6/9/2004]
Combat Air Patrol Is Established by 10:00 a.m. - F-16 fighters that were scrambled from Langley Air Force Base, Virginia, at 9:24 a.m. (see 9:24 a.m. September 11, 2001) reach Washington and set up a CAP over the city at 9:49 a.m., according to a timeline provided to CNN by “informed defense officials.” [CNN, 9/17/2001] The 9/11 Commission, however, will conclude that the F-16s establish the CAP at “approximately 10:00 a.m.” (see (Between 9:49 a.m. and 11:00 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 34] This would mean that NORAD informs the air threat conference call that a CAP has been established over Washington at around 10:39 a.m. to 10:50 a.m., according to the NMCC’s after-action report.
Transcripts Suggest NORAD Reports the CAP at a Later Time - However, transcripts of the air threat conference call will indicate that NORAD reports that a CAP has been established over Washington even later than this, at 10:55 a.m. At about 10:08 a.m., the NORAD representative on the conference is asked if they can provide “information on fighter coverage over the Washington area.” The NORAD representative says, “We have no further information at this point.” At 10:40 a.m., the NORAD representative indicates that a CAP has not yet been established, but will be soon. They report: “We have confirmation currently of two fighters… currently inbound. Estimate time 10 minutes overhead at CAP point north of Langley [Air Force Base] for protection of the Washington, DC, area.”
NORAD Says the CAP Has Been Established at 10:55 a.m. - But 13 minutes later, at 10:53 a.m., the NORAD representative says there is still no CAP over Washington. They report, “We have two F-16s scrambling out of Andrews Air Force Base,” just outside Washington (see 10:42 a.m. September 11, 2001), but add that there is “no airborne CAP at this time.” Two minutes later, the NORAD representative indicates that a CAP has at last been set up over Washington. “We have a report of two fighters airborne over DC,” they say. At around 11:05 a.m., the NORAD representative will be asked to confirm “that two F-16s are still on CAP in the vicinity of Washington” and they will reply, “That is affirmative.” [US Department of Defense, 9/11/2001 pdf file; US Department of Defense, 9/11/2001]

Rich Miles, the manager of United Airlines’ System Operations Control center outside Chicago, tries to initiate the “lockout” procedure for Flight 93, which would acknowledge an emergency on the flight and safeguard information about it, but he is unable to do so. At some time between 9:45 a.m. and 9:50 a.m., the United Airlines maintenance facility in San Francisco contacted Miles about a call it had just received from an attendant on Flight 93, reporting that her plane had been hijacked (see 9:35 a.m. September 11, 2001). In response, Miles attempts to initiate a lockout of Flight 93. Lockout is a standard procedure for airlines in safety and security incidents, which isolates information about a flight so the case can be managed by the airline’s top leadership, and protects the identities of the passengers and crew. But Miles is unable activate this procedure. According to the 9/11 Commission, this is because United Airlines has already conducted a lockout of Flight 175 (see (9:21 a.m.) September 11, 2001), and its computer system is not presently set up to deal simultaneously with two such procedures.

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

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

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).

Members of New York Police Department’s elite Emergency Service Unit (ESU) are given an order that means they have to get out of the World Trade Center or delay entering it and consequently many of them will avoid being killed when the South Tower collapses, at 9:59 a.m. [Keegan and Davis, 2006, pp. 101-102; Appel, 2009, pp. 112-113] The ESU is a highly trained organization comprised of first response rescuers. [City of New York, 6/29/2002] Its members respond to situations that require the most specialized training, such as hostage taking and water rescue, and use the most advanced equipment. [Keegan and Davis, 2006, pp. 101]
Officers Are Ordered to Come Down from the WTC - Inspector Ronald Wasson, commanding officer of the ESU, earlier on divided his officers into four teams of five or six men and then sent two teams into each of the Twin Towers to assist the rescue operation. [New York Daily News, 11/11/2001] But now, ESU commanders give the order for the unit’s members to “go tactical.” This means the officers in the towers have to come out of the buildings and go to the unit’s SWAT (special weapons and tactics) vans; put on their BDU (battle dress uniform) suits, flak jackets, and Kevlar helmets; and arm themselves with heavy weapons and assault rifles.
Commander Thinks Terrorists Might Attack the First Responders - The decision to order ESU officers to go tactical is made by Wasson, according to a book by Lieutenant William Keegan of the Port Authority Police Department. [Keegan and Davis, 2006, pp. 101-102] Wasson is currently assembled with a number of other ESU officers outside the Twin Towers, at the corner of West and Vesey Streets. [Appel, 2009, pp. 68] He decides that ESU officers should go tactical due to his concern that armed terrorists might attack the first responders at the WTC. He is “worried that with all his personnel inside the buildings, he [has] no way to protect the cops, firefighters, or civilians from the kind of low-intensity warfare—snipers, automatic weapons, car bombs, hostage situations—he [is] sure [will] follow the attack,” Keegan will write. He believes it is the responsibility of the New York Fire Department to deal with the fires in the Twin Towers, while the Police Department should be preparing for what might happen next. Many ESU members will come out of the towers after receiving the order to go tactical, according to Keegan. [Keegan and Davis, 2006, pp. 101-102]
Order Is Given after an Officer Hears of the Pentagon Attack - However, according to author Anthea Appel, the order to go tactical is made by Sergeant Tom Sullivan, another ESU officer. Sullivan is currently at the corner of West and Vesey Streets along with Wasson, getting ready to take two teams into the WTC. At 9:56 a.m., after hearing over his radio about the attack on the Pentagon, which occurred at 9:37 a.m. (see 9:37 a.m. September 11, 2001), he exclaims, “Screw rescue!” He then pulls his men back and announces that all ESU teams will be “going in tactical,” according to Appel. “I want heavy vests, helmets, rifles, and machine guns,” he says. In response to his announcement, ESU officers start taking off their rescue gear and putting on combat gear. They take off their safety helmets and replace them with ballistic helmets. They take off their air tanks, unbuckle their Roco harnesses, and put on more body armor over their bulletproof vests. They also unlock their gun bins and take out shotguns, submachine guns, and assault rifles. Some officers grumble under their breath, annoyed at being held back. “They didn’t like wasting time fiddling around with equipment,” Appel will comment, “and this sudden switch interrupted their adrenaline momentum.” They will be in the middle of changing into their combat gear when the South Tower collapses (see 9:59 a.m. September 11, 2001). [Appel, 2009, pp. 112-113]
Order Is Wrong but Saves Lives - The order to go tactical will turn out to be mistaken as there are no attacks by armed terrorists on the first responders at the WTC. However, as a result of it being issued, numerous ESU members will be outside the Twin Towers instead of inside the buildings when the South Tower comes down and many of them will therefore avoid being killed in the collapse. While 14 ESU members will die in the WTC collapses, a far greater number will survive, Keegan will write, “because Wasson’s order pulled them out of the towers and saved their lives.” [Keegan and Davis, 2006, pp. 102] One ESU member, Detective Frank DeMasi, will conclude that Sullivan “definitely saved his life when he made that last-minute decision to switch from rescue to tactical mode,” according to Appel, since the delay while they changed into their combat gear “kept DeMasi and his teammates from walking into the South Tower before it collapsed.” [Appel, 2009, pp. 265-266]

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

NORAD’s Northeast Air Defense Sector (NEADS) receives a call from a NORAD unit in Canada, reporting another suspected hijacked aircraft that is heading south from Canada, across the border toward Washington, DC. [Vanity Fair, 8/1/2006]
Aircraft Reported on Chat System - A member of staff at NEADS relays to their colleagues that the aircraft is from an “unknown departure airport, heading towards Washington,” but they do not “know any codes or anything” else about it. [North American Aerospace Defense Command, 9/11/2001] Another member of staff at NEADS calls the Canadian unit for more information. A Lance Corporal Nicholson there says only that he has seen “something on the chat” about a “possible” aircraft. [North American Aerospace Defense Command, 9/11/2001; North American Aerospace Defense Command, 9/11/2001] (Nicholson is presumably referring to NORAD’s computer chat system. [Spencer, 2008, pp. 139] )
Fighter Unit Contacted - According to author Lynn Spencer, NEADS battle commander Colonel Robert Marr contacts a military unit in Syracuse, New York, to get fighter jets sent after the suspicious flight. [Spencer, 2008, pp. 223] However, the first jets to launch from Syracuse will not take off until 10:42 a.m. (see 10:42 a.m. September 11, 2001). [Post-Standard (Syracuse), 9/12/2001]
Report Is a False Alarm - The suspected hijacking is soon revealed to be a false alarm. Nicholson will call from Canada and tell NEADS: “Be advised… that our [intelligence team] is not assessing that there is an actual aircraft problem. It’s just that there could be problems from our area.… There’s no actual aircraft that we suspect as being a danger.” He will add that his intelligence people “haven’t got any particular aircraft in mind.” [North American Aerospace Defense Command, 9/11/2001; Vanity Fair, 8/1/2006]
Numerous Erroneous Reports - This is one of the numerous mistaken reports of hijackings received during the course of the morning (see (9:09 a.m. and After) September 11, 2001). According to Vanity Fair: “In the barrage of information and misinformation, it becomes increasingly difficult for the controllers [at NEADS] to keep count of how many suspected hijackings are pending. So far, it is known that three have hit buildings, but given the uncertainty about the fates of American 11 and American 77—no one knows yet that this is the plane that hit the Pentagon—the sense at NEADS is that there are possibly three hijacked jets still out there, and who knows how many more yet to be reported.” At the time NEADS is informed of the suspicious aircraft coming in from Canada, “no one on the military side is aware that United 93 has been hijacked.” [Vanity Fair, 8/1/2006]

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

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

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: Vanity Fair] (click image to enlarge)One of the pilots that took off from Langley Air Force Base (see (9:25 a.m.-9:30 a.m.) September 11, 2001) calls NORAD’s Northeast Air Defense Sector (NEADS) to relay information he has received about an aircraft over the White House, and is promptly instructed to intercept this aircraft. [Vanity Fair, 8/1/2006]
Borgstrom Wants Instructions - The three F-16s that took off from Langley Air Force Base are now flying in the Baltimore-Washington area. They have just heard a warning over the radio that errant aircraft will be shot down, and received an instruction from the Secret Service to protect the White House (see (10:00 a.m.) September 11, 2001). The FAA’s Washington Center also notified them of a suspicious aircraft flying at high speed toward the White House. In response, pilot Craig Borgstrom radios NEADS and asks weapons director Steve Citino for instructions on what to do. [Spencer, 2008, pp. 222-223] Borgstrom says: “Baltimore [the Washington Center] is saying something about an aircraft over the White House. Any words?” Citino replies: “Negative. Stand by,” and then relays Borgstrom’s message to Major James Fox, the leader of the NEADS weapons team. Fox then notifies Major Kevin Nasypany, the NEADS mission crew commander, of the aircraft over the White House.
Ordered to Intercept - Instinctively, Nasypany responds, “Intercept!” and he then elaborates, “Intercept and divert that aircraft away from there.” Citino passes this instruction to the Langley fighters, telling them their mission is to “intercept aircraft over White House. Use FAA for guidance.” Fox then adds: “Divert the aircraft away from the White House. Intercept and divert it.” Borgstrom confirms the order, saying, “Divert the aircraft.”
Unidentified Aircraft a False Alarm - As the F-16s head for the White House, the NEADS controllers are unable to find the building on their dated equipment, and also have trouble communicating with the Langley pilots. NEADS personnel speculate that the unidentified object is probably just a helicopter or smoke from the burning Pentagon. Minutes later, the suspect aircraft will be realized to probably be one of the Langley fighters, mistakenly reported by a Washington Center air traffic controller who was unaware of the military’s scrambles. Citino will comment: “That was cool. We intercepted our own guys.” [North American Aerospace Defense Command, 9/11/2001; Vanity Fair, 8/1/2006]

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

The mission crew commander at NORAD’s Northeast Air Defense Sector (NEADS) tells members of his staff that the fighter jets launched from Langley Air Force Base (see (9:25 a.m.-9:30 a.m.) September 11, 2001) have “negative clearance to shoot” aircraft over Washington. [North American Aerospace Defense Command, 9/11/2001; 9/11 Commission, 6/17/2003; Vanity Fair, 8/1/2006; Spencer, 2008, pp. 226-227]
Marr Does Not Pass on Authorization - NEADS battle commander Colonel Robert Marr has just been talking on the phone with Major General Larry Arnold, the commander of NORAD’s Continental US Region, and the two men have discussed whether fighters should be authorized to shoot down hostile aircraft (see (10:08 a.m.-10:10 a.m.) September 11, 2001). According to author Lynn Spencer, Arnold told Marr that if a suspicious aircraft cannot be diverted, “then we’ll shoot it down.” However, this is not the instruction that Marr then passes on to Major Kevin Nasypany, the NEADS mission crew commander. [Spencer, 2008, pp. 225-227] Marr will later tell the 9/11 Commission that at this time, he “may have had the authority” to order a plane shot down, “but he never gave [Nasypany] clearance to fire.” Marr “does not believe at this point there was a clearance to ‘kill.’” [9/11 Commission, 1/23/2004 pdf file]
Order Issued: 'Negative Clearance to Fire' - Nasypany relays the instructions Marr gives him to those on the operations floor, saying: “Negative. Negative clearance to shoot.” He then adds: “ID. Type. Tail.” This means the orders are for fighter jets to identify aircraft by their type and tail number, and nothing more. [North American Aerospace Defense Command, 9/11/2001; 9/11 Commission, 8/26/2004, pp. 46-47; Vanity Fair, 8/1/2006] About a minute later, Nasypany’s instructions will be passed to the Langley pilots (see 10:11 a.m. September 11, 2001).

A weapons director at NORAD’s Northeast Air Defense Sector (NEADS) informs the fighter jets launched from Langley Air Force Base (see (9:25 a.m.-9:30 a.m.) September 11, 2001) that they do not have permission to shoot down aircraft over Washington, though he is delayed in giving this instruction due to communications problems.

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

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

With reports of another airplane headed toward Washingon, fire and rescue workers were directed to temporarily move away from the Pentagon.With reports of another airplane headed toward Washingon, fire and rescue workers were directed to temporarily move away from the Pentagon. [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).

[Source: Jodi Joice / US Air Force]Two F-16 fighter jets take off from a military unit in Toledo, Ohio, in response to the morning’s attacks, but accounts will conflict over what their mission is and who the pilots are. [Toledo Blade, 12/9/2001; Filson, 2003, pp. 71; WTOL, 9/11/2006] The 180th Fighter Wing of the Ohio Air National Guard is based at Toledo Express Airport. Although the unit is not one of NORAD’s seven alert facilities around the US, it has recently received a call from NORAD’s Northeast Air Defense Sector (NEADS), requesting that it launch two of its fighters (see 10:01 a.m. September 11, 2001). [Airman, 12/1999; Toledo Blade, 12/9/2001; WTOL, 9/11/2006; Spencer, 2008, pp. 178-179] The 180th Maintenance Squadron, which is responsible for maintaining the unit’s aircraft and equipment, was also contacted, and has loaded the F-16s’ guns with 500 rounds of 20-caliber ammunition. [180th Fighter Wing, 9/19/2001; WTOL, 9/11/2006]
Jets Head East - The two F-16s, which were being set up for training missions, now take off and head east. [Toledo Blade, 12/9/2001] According to author Lynn Spencer, they are piloted by Scott Reed and Ed Rinke. [Spencer, 2008, pp. 179] However, a local television station will report that the pilots are Scott Reed and Keith Newell. [WTOL, 9/11/2006]
Mission Unclear - It is unclear what role the two jets play in defending the nation. Toledo Air National Guard officials will later refuse to talk about this morning’s events, even in the general terms permitted by the military. [Toledo Blade, 12/9/2001] According to Spencer, NEADS wanted the 180th FW jets to respond to Delta Air Lines Flight 1989, which is incorrectly thought to have been hijacked and will land in Cleveland at around 10:18 (see (10:18 a.m.) September 11, 2001). The 9/11 Commission will similarly say the Toledo jets are ordered to intercept Delta 1989. [Federal Aviation Administration, 9/16/2001; 9/11 Commission, 7/24/2004, pp. 27-28; Spencer, 2008, pp. 177-178] But Larry Arnold, the commander of the Continental United States NORAD Region, will say the 180th FW was contacted “because we thought [Flight] 93 or Delta Flight 1989 might be headed toward Chicago.” [Filson, 2003, pp. 71] NEADS battle commander Colonel Robert Marr will say the two F-16s “never had a track close enough that they were directed to engage. [But] if a valid direction had come from the appropriate level to engage a target, or shoot down a target at some time, they could have done that.”
Response Is 'Very Quick' - Marr will describe the 180th FW’s response to NEADS’s request for assistance as “very, very, very quick.” [Toledo Blade, 12/9/2001] However, the fourth hijacked aircraft, Flight 93, has already crashed by the time the two jets take off (see (10:06 a.m.) September 11, 2001).

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

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

Personnel in the White House Situation Room learn of a plane supposedly flying toward the United States from Europe that appears to be hijacked, but it is subsequently determined that the alleged flight does not exist. Those in the Situation Room receive word confirming that a suspicious Northwest Airlines flight from Portugal to Philadelphia is heading toward Washington, DC. The plane is not responding to radio calls and its transponder is squawking the code for a hijacking. White House counterterrorism chief Richard Clarke gives orders for someone to find out more about the flight and what assets the US military has available to intercept it at the coast. Meanwhile, the FAA searches its data for information about the flight and officials try to contact Northwest Airlines to find out more. Those participating in Clarke’s video teleconference (see (9:10 a.m.) September 11, 2001 and 9:25 a.m. September 11, 2001) grow increasingly anxious, since no action can be taken until more details about the flight are found. Then Timothy Flanigan, the deputy White House counsel, who is in the Situation Room, has an idea. He leaves the room and finds an unsecure computer. On this, he searches travel websites for details of the suspicious flight, but finds nothing. He then checks on the Northwest Airlines website and again finds no reference to the flight. He quickly jots down everything he can find about Northwest Airlines flights from Europe and then goes to pass on his findings. After taking a seat at the conference table, he addresses Clarke, who is still searching for information about the plane. “I’ve checked and there’s no such flight,” he says. Astonished at this news, Clarke asks, “How did you check?” “I looked on their website,” Flanigan replies. Clarke then passes on the news to the other participants in the video teleconference. “I have information that there is no such flight,” he says and adds, “Check that again.” [Eichenwald, 2012, pp. 36-37] The 9/11 Commission Report will later note that there are “multiple erroneous reports of hijacked aircraft” this morning (see (9:09 a.m. and After) September 11, 2001).

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