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

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

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. [Freni, 2003, pp. 29; 9/11 Commission, 7/24/2004, pp. 460; 9/11 Commission, 8/26/2004, pp. 30 pdf file]
Airline and Possibly Pentagon Learn of Flight 77 Problems - While NEADS is not alerted about the errant aircraft, a controller at the Indianapolis Center will contact American Airlines at 8:58 to inform it that contact has been lost with Flight 77 (see 8:58 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 30 pdf file] And an article in the New York Times will indicate that the Pentagon’s National Military Command Center (NMCC) promptly becomes aware of the problems with Flight 77 (see (Shortly After 8:51 a.m.) September 11, 2001).

An air traffic controller at the FAA’s Indianapolis Center contacts the American Airlines dispatch office in Texas, and informs it that contact has been lost with Flight 77. The controller is a sector radar associate, whose job is to help with hand-offs and to coordinate with other sectors and facilities. He speaks to American Airlines dispatcher Jim McDonnell. [9/11 Commission, 8/26/2004, pp. 30 pdf file; Spencer, 2008, pp. 63] The controller begins, “This is Indianapolis Center trying to get a hold of American 77.” McDonnell asks for clarification, “Who you trying to get a hold of?” and the controller replies: “American 77.… On frequency 120.27.… We were talking to him and all of a sudden it just, uh…” McDonnell interjects: “Okay, all right. We’ll get a hold of him for you.” The call comes to an abrupt end and the controller then continues trying to contact Flight 77. [New York Times, 10/16/2001; Spencer, 2008, pp. 63-64] Soon after this call, American Airlines’ executive vice president of operations, Gerard Arpey, will give an order to stop all American flight takeoffs in the Northeast US (see Between 9:00 a.m. and 9:10 a.m. September 11, 2001). By 8:59 a.m., American Airlines begins attempts to contact Flight 77 using ACARS (a digital communications system used primarily for aircraft-to-airline messages). Within minutes, some time between 9:00 a.m. and 9:10 a.m., American will get word that United Airlines also has lost contact with a missing airliner (presumably Flight 175). When reports of the second WTC crash come through after 9:03 a.m., one manager will mistakenly shout, “How did 77 get to New York and we didn’t know it?” [Wall Street Journal, 10/15/2001; 9/11 Commission, 7/24/2004, pp. 454; 9/11 Commission, 8/26/2004, pp. 31 pdf file] The sector radar associate at the Indianapolis Center will call American Airlines again about Flight 77 at 9:02, and again speak with McDonnell (see 9:02 a.m. September 11, 2001).

According to CIA Director George Tenet, “Only minutes” after the South Tower is hit, the CIA’s Counterterrorist Center (CTC) receives a report that at least one other commercial passenger jet plane is unaccounted for. [Tenet, 2007, pp. 163] The CTC is based at the CIA headquarters in Langley, and is run by the agency’s operations division. It gathers intelligence and runs covert operations abroad. It employs hundreds of analysts, and includes experts assigned from Defense Department intelligence agencies, the Pentagon’s Central Command, the FBI, the National Security Agency, the Federal Aviation Administration, and other government agencies. According to the Los Angeles Times, “It serves as the nerve center for the CIA’s effort to disrupt and deter terrorist groups and their state sponsors.” [St. Petersburg Times, 10/2/2001; Los Angeles Times, 10/12/2001] Further details of the unaccounted-for plane, and where the CTC learns of it from, are unclear. The plane is presumably Flight 77, which veered off course at 8:54 (see (8:54 a.m.) September 11, 2001), and was evidently lost by 8:56 (see 8:56 a.m. September 11, 2001). [New York Times, 10/16/2001; 9/11 Commission, 7/24/2004, pp. 9] The FAA will later claim it had established several phone bridges at around 8:50 a.m., which included various government agencies, on which it shared “real-time information… about the unfolding events, including information about loss of communication with aircraft, loss of transponder signals, unauthorized changes in course, and other actions being taken by all the flights of interest, including Flight 77” (see (8:50 a.m.) September 11, 2001). [9/11 Commission, 5/23/2003] So the CTC may have learned of the errant plane by this means. Yet the 9/11 Commission will claim the FAA’s phone bridges were not established until about 9:20 (see (9:20 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 36] And NORAD is supposedly only alerted to Flight 77 at 9:24, according to some accounts (see (9:24 a.m.) September 11, 2001), or 9:34, according to others (see 9:34 a.m. September 11, 2001).

An air traffic controller at the FAA’s Indianapolis Center, which was monitoring Flight 77 when it disappeared from radar (see 8:56 a.m. September 11, 2001 and (8:56 a.m.-9:05 a.m.) September 11, 2001), learns for the first time that there has been at least one hijacking—of Flight 11—this morning, and that planes have crashed into the World Trade Center. Yet, after he passes this information on to a colleague, neither controller suspects that the missing Flight 77 might also be hijacked. [9/11 Commission, 7/24/2004, pp. 24; Spencer, 2008, pp. 105-107]
Dispatcher Gives Details of Crisis - The controller, a sector radar associate at the Indianapolis Center, calls the American Airlines dispatch office in Texas and overhears dispatcher Jim McDonnell on another call, discussing the morning’s crisis. He hears McDonnell saying, “… and it was a Boston-LA flight and [Flight] 77 is a Dulles-LA flight and, uh, we’ve had an unconfirmed report a second airplane just flew into the World Trade Center.” McDonnell then acknowledges the Indianapolis Center controller, who asks, “Did you get a hold of American 77 by chance?” McDonnell answers, “No sir, but we have an unconfirmed report the second airplane hit the World Trade Center and exploded.” The controller asks, “Say again?” McDonnell tells him: “You know, we lost American 11 to a hijacking. American 11 was a Boston to Los Angeles flight.” The controller seems shocked, saying: “I can’t really… I can’t hear what you’re saying there. You said American 11?” McDonnell replies, “Yes, we were hijacked… and it was a Boston-LA flight, and [Flight] 77 is a Dulles-LA flight and, uh, we’ve had an unconfirmed report a second airplane just flew into the World Trade Center.” The controller then abruptly ends the call, saying: “Thank you very much. Goodbye.” [New York Times, 10/16/2001; Spencer, 2008, pp. 106]
Controllers Make No Connection with Flight 77 - After hanging up, the Indianapolis Center controller immediately calls another of the center’s radar associates and repeats what he has just heard. They look through their flight plans but can find no record of Flight 11 in their system. According to author Lynn Spencer, the center’s host computer, which performs critical radar and flight management functions, only holds on to active flight plans. Therefore, several minutes after the system had stopped tracking the transponder data tag for Flight 11, its flight plan dropped out of the system. According to Spencer, the two controllers fail to connect what McDonnell has said with the disappearance of Flight 77: “The best the controllers can figure is that [Flight 11] was hijacked on the ground in New York and proceeded to take off for Los Angeles without a clearance. They’re not sure just how this is relevant to the disappearance of American 77, if at all, and they’ve done all they can do for now.… Confused, they return to their jobs.” [Spencer, 2008, pp. 106-107]
Hijacking Not Suspected - At 9:08, the Indianapolis Center contacted Air Force Search and Rescue to request that it be on the lookout for an accident involving Flight 77 (see (After 9:00 a.m.) September 11, 2001), and at 9:09 it informs the FAA regional office of a possible accident involving Flight 77 (see 9:09 a.m. September 11, 2001). However, according to the 9/11 Commission, it is not until about 9:20 that the center begins to doubt its initial assumption that Flight 77 has crashed, and discusses this concern with the FAA’s Herndon Command Center (see (9:20 a.m.-9:21 a.m.) September 11, 2001).

An air traffic controller at the FAA’s Indianapolis Center, which was monitoring Flight 77 when it disappeared from radar (see 8:56 a.m. September 11, 2001 and (8:56 a.m.-9:05 a.m.) September 11, 2001), receives confirmation from American Airlines that Flight 11 was hijacked, but apparently still does not suspect that the missing Flight 77 may also have been hijacked. [New York Times, 10/16/2001; 9/11 Commission, 7/24/2004, pp. 24] The controller, a sector radar associate at the Indianapolis Center, called the American Airlines dispatch office in Texas five minutes earlier, and was informed by dispatcher Jim McDonnell that Flight 11 had been hijacked and that two planes had hit the World Trade Center (see 9:09 a.m. September 11, 2001). [Spencer, 2008, pp. 106] He now calls the dispatch office and again speaks with McDonnell. After introducing himself, he asks, “American 11, you guys said he departed off of, uh, New York?” McDonnell replies, “Boston.” The controller continues, “Boston, he was going to LA, and it was a hijacked airplane?” McDonnell confirms, “Yes.” The controller asks, “And you, have you heard anything from American 77?” McDonnell replies, “No,” and then adds, “I talked to a winder in the center up there, and I gave them the information I got.” (What McDonnell is referring to here is unclear.) The controller thanks McDonnell, and the call ends. [New York Times, 10/16/2001] Despite receiving this information from American Airlines, according to the 9/11 Commission it is not until about 9:20 that the Indianapolis Center begins to doubt its initial assumption that Flight 77 has crashed, and discusses this concern with the FAA’s Herndon Command Center (see (9:20 a.m.-9:21 a.m.) September 11, 2001).

According to the 9/11 Commission, the FAA’s Indianapolis Center, which was monitoring Flight 77 when it disappeared from radar (see 8:56 a.m. September 11, 2001 and (8:56 a.m.-9:05 a.m.) September 11, 2001), has learned by 9:20 a.m. that there are “other hijacked aircraft,” and begins “to doubt its initial assumption that American 77 had crashed.” [9/11 Commission, 7/24/2004, pp. 24] In fact, a transcript of air traffic controller communications will show that the Indianapolis Center was informed of the Flight 11 hijacking, and that two planes had hit the World Trade Center, at 9:09 a.m. (see 9:09 a.m. September 11, 2001); five minutes later, it received confirmation of the Flight 11 hijacking (see 9:14 a.m. September 11, 2001). [New York Times, 10/16/2001] And television networks have been covering the crashes in New York since as early as 8:48 a.m. (see 8:48 a.m. September 11, 2001). [Bamford, 2004, pp. 16-17]
Other Facilities Notified - The manager at the Indianapolis Center now discusses the concern that Flight 77 may not have crashed with the FAA’s Command Center in Herndon, Virginia. This discussion prompts the Command Center to notify some FAA field facilities that Flight 77 is lost. [9/11 Commission, 8/26/2004, pp. 32 pdf file] Also at around 9:20, the Indianapolis Center operations manager contacts the FAA’s Chicago Center. He advises its operations manager of his concern that Flight 77 may have been hijacked, and says to be on the lookout, based on the events that have occurred in New York. [Federal Aviation Administration, 9/17/2001 pdf file] By 9:21, according to the 9/11 Commission, the FAA “Command Center, some FAA field facilities, and American Airlines had started to search for American 77. They feared it had been hijacked.” [9/11 Commission, 7/24/2004, pp. 24-25]

[Federal Aviation Administration, 9/17/2001 pdf file; 9/11 Commission, 8/26/2004, pp. 32 pdf file] This is almost 30 minutes after this loss of contact occurred (see 8:56 a.m. September 11, 2001), and 15 minutes after the Great Lakes regional center was informed of it (see 9:09 a.m. September 11, 2001).

Todd Lewis.Todd Lewis. [Source: NBC]After air traffic controllers at Washington Dulles International Airport notice an unidentified aircraft, later determined to be Flight 77, approaching Washington on their radar screens (see (Between 9:25 a.m. and 9:30 a.m.) September 11, 2001 and 9:32 a.m. September 11, 2001), they initially think it is a military fighter plane, due to its high speed and the way it is being flown. [ABC News, 10/24/2001; 9/11 Commission, 7/24/2004, pp. 9] Yet the alleged hijacker pilot of Flight 77 has been known for his poor flying skills. [Washington Post, 9/30/2001; New York Times, 5/4/2002]
Aircraft Performs Elaborate Maneuver - The Dulles controllers are unable to identify the plane because its transponder—which transmits identifying information about an aircraft to radar screens—has been turned off (see 8:56 a.m. September 11, 2001). [Washington Post, 9/11/2001; Washington Post, 9/12/2001] It is flying at almost 500 miles per hour while approaching Washington, and then performs a rapid downward spiral, “dropping the last 7,000 feet in two and a half minutes,” before hitting the Pentagon (see 9:34 a.m.- 9:37 a.m. September 11, 2001). [CBS News, 9/21/2001; USA Today, 8/13/2002]
Moving 'Like a Military Aircraft' - Controller Danielle O’Brien will later recall: “The speed, the maneuverability, the way that he turned, we all thought in the radar room, all of us experienced air traffic controllers, that that was a military plane. You don’t fly a 757 in that manner. It’s unsafe.” [ABC News, 10/24/2001] Another controller, Todd Lewis, will recall: “[N]obody knew that was a commercial flight at the time. Nobody knew that was American 77.… I thought it was a military flight. I thought that Langley [Air Force Base] had scrambled some fighters and maybe one of them got up there.… It was moving very fast, like a military aircraft might move at a low altitude.” [MSNBC, 9/11/2002]
Alleged Pilot 'Could Not Fly at All' - Yet many people who have met Hani Hanjour, the hijacker allegedly at the controls of Flight 77, considered him to be a very poor pilot (see October 1996-December 1997, 1998, February 8-March 12, 2001, and (April-July 2001)). Just a month previously, an airport refused to rent him a single-engine Cessna plane because instructors there found his flying skills so weak (see Mid-August 2001). [Gazette (Greenbelt), 9/21/2001; Newsday, 9/23/2001] And an employee at a flight school Hanjour attended earlier in the year will later comment: “I’m still to this day amazed that he could have flown into the Pentagon. He could not fly at all” (see January-February 2001). [New York Times, 5/4/2002]

Danielle O’Brien.Danielle O’Brien. [Source: ABC News]At 9:32 a.m., according to the 9/11 Commission, several air traffic controllers at Washington Dulles International Airport notice a fast-moving target, which is later determined to be Flight 77, heading eastbound on their radar screens. [9/11 Commission, 7/24/2004, pp. 25; 9/11 Commission, 8/26/2004, pp. 33 pdf file] At the Terminal Radar Approach Control (TRACON) at Dulles Airport, which is 22 miles west of the Pentagon, controllers have been searching for primary radar targets since 9:21, when the facility was notified of the loss of contact with Flight 77 (see 9:21 a.m. September 11, 2001). [USA Today, 9/13/2001; Navy Times, 9/22/2001; 9/11 Commission, 7/24/2004, pp. 25]
Controllers See Fast-Moving Radar Track - They now notice an unidentified blip on their screens, heading toward the White House at unusually high speed. [Washington Post, 9/11/2001; Spencer, 2008, pp. 145] Controller Danielle O’Brien will later recall: “I noticed the aircraft. It was an unidentified plane to the southwest of Dulles, moving at a very high rate of speed.… I had literally a blip and nothing more. I slid over to the controller on my left, Tom Howell, and I asked him, ‘Do you see an unidentified plane there southwest of Dulles?’ And his response was, ‘Yes. Oh, my gosh, yes! Look how fast he is.’” According to O’Brien, the aircraft is between 12 and 14 miles away when she notices it. It is heading for what is known as Prohibited Area 56 (P-56), which is the airspace over and near the White House, at a speed of about 500 miles per hour. [ABC, 10/24/2001; ABC News, 10/24/2001; Department of Transportation, 8/4/2005] Because the plane’s transponder has been turned off (see 8:56 a.m. September 11, 2001) its identity and type are presently unknown, and the Dulles controllers initially think it is a military aircraft (see (9:25 a.m.-9:37 a.m.) September 11, 2001). [Washington Post, 9/12/2001; ABC News, 10/24/2001; 9/11 Commission, 7/24/2004, pp. 25]
TRACON Notifies Others - The Dulles TRACON alerts Washington’s Reagan National Airport (see (9:33 a.m.) September 11, 2001) and the Secret Service (see (9:33 a.m.) September 11, 2001) to the approaching aircraft. Its operations supervisor also provides continuous updates over a teleconference that has been established at the FAA’s headquarters. [Federal Aviation Administration, 9/17/2001 pdf file; 9/11 Commission, 7/24/2004, pp. 25] According to an FAA chronology that is published shortly after 9/11, the Dulles TRACON controllers notice the unidentified aircraft earlier than the 9/11 Commission says, at between 9:25 and 9:30 (see (Between 9:25 a.m. and 9:30 a.m.) September 11, 2001).

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