9/11 Timeline

John Ogonowski, who will pilot American Airlines Flight 11—the first plane to hit the World Trade Center—on 9/11, is not originally supposed to be on that flight, but is scheduled to fly it shortly before September 11. The original pilot is Walter Sorenson. But, according to the Georgetown Record, Sorenson is “disappointed when he [is] replaced by Captain John Ogonowski, who [has] seniority over Sorenson and requested to fly [on 9/11].” [Georgetown Record, 9/18/2003; Georgetown Record, 9/7/2005] However, other reports indicate Ogonowski is later unhappy about having to fly on September 11, and tries, unsuccessfully, to switch to another flight. [Public Radio International, 9/13/2002] Thomas McGuinness, who will be the co-pilot of Flight 11 on 9/11, is, like Ogonowski, not originally supposed to be on that flight, but arranges to take it on the afternoon before September 11 (see September 10, 2001). [Peter Scheibner, 8/30/2011; KSAX, 1/20/2012] Pilots on two of the other aircraft hijacked on 9/11 are also not originally scheduled to fly that day, but are booked onto those planes shortly before September 11 (see Shortly Before September 11, 2001 and Shortly Before September 11, 2001). [New York Times, 9/13/2001; Denver Post, 12/16/2001; MSNBC, 9/11/2006]

Pilot Jason Dahl, who will be at the controls of United Airlines Flight 93—the fourth hijacked aircraft—on 9/11, is not originally scheduled for that flight, but wants to get in extra hours so he can take time off work for his fifth wedding anniversary on September 14. [Pittsburgh Post-Gazette, 10/28/2001; MSNBC, 9/11/2006] Therefore, some time shortly before 9/11, he trades a trip later in September in order to fly September 11. [Denver Post, 12/16/2001; Longman, 2002, pp. 1] Yet the week before September 11, he sends out an e-mail seeking another pilot to take his place, so he can have that day with his family. [Rocky Mountain News, 9/12/2001; New York Times, 9/15/2001; San Francisco Chronicle, 9/17/2001] Pilots on two of the other aircraft hijacked on 9/11 are also not originally scheduled to fly that day, but are booked onto those planes shortly before September 11 (see September 10, 2001, Shortly Before September 11, 2001, and Shortly Before September 11, 2001).

Willie Brown. [Source: San Francisco City Government]Eight hours prior to the terrorist attacks, San Francisco Mayor Willie Brown receives a warning from his “security people at the airport,” advising him to be cautious in traveling. [San Francisco Chronicle, 9/12/2001] Later reports will claim that this is because someone saw the State Department warning of September 7 (see September 7, 2001), which focused on the threat to military personnel in Asia. Brown is scheduled to fly to New York the next morning. [US Department of State, 9/7/2001; San Francisco Chronicle, 9/12/2001; San Francisco Chronicle, 9/14/2001] The source of the warning, and why it is personally issued to Brown, will remain unknown.

Chris Lyons, a newspaper delivery driver, sees four or five Middle Eastern men near the entrance of Portland airport, from where alleged hijackers Mohamed Atta and Abdulaziz Alomari will later take a plane to Boston (see (6:00 a.m.) September 11, 2001). The men are speaking Arabic among themselves and hauling about ten suitcases into the airport. Lyons later says they “stuck out because usually no one is around at that hour.” After 9/11, local police will say they don’t think the men are connected to the attacks. However, Lyons is concerned that they might have been “support people,” because, he says, “It’s just too much of a coincidence that this group of businessmen was leaving Portland the morning of the terrorist attacks.” [Portland Press Herald, 9/22/2001; Portland Press Herald, 10/21/2001]

Abdulaziz Alomari (a passport stamp overlaps part of his face). [Source: FBI]Having spent the previous night at the Comfort Inn in Portland, Maine (see September 10, 2001), hijackers Mohamed Atta and Abdulaziz Alomari check out at 5:33 a.m. and drive their rented Nissan to the nearby Portland International Jetport Airport, entering its parking lot at 5:40 a.m. The FBI will later seize their car there. [Observer, 9/16/2001; Portland Press Herald, 10/5/2001; Federal Bureau of Investigation, 10/5/2001; Newsday, 4/17/2006] Their flight is due to take off for Boston at 6:00 a.m. (see (6:00 a.m.) September 11, 2001). The Boston Globe points out, “Any significant delay would foil [Atta’s] big plans for the day.” [Boston Globe, 9/16/2001] The 9/11 Commission later concludes: “The Portland detour almost prevented Atta and Omari from making Flight 11 out of Boston.” [9/11 Commission, 6/16/2004]

Michael Tuohey. [Source: CNN]9/11 hijackers Mohamed Atta and Abdulaziz Alomari check in at the US Airways counter at Portland International Jetport. [Portland Press Herald, 10/5/2001; Federal Bureau of Investigation, 10/5/2001] They are wearing ties and jackets. Atta checks in two bags, Alomari none. Atta is randomly selected for additional security scrutiny by the FAA’s Computer Assisted Passenger Prescreening System (CAPPS) (see (6:20 a.m.-7:48 a.m.) September 11, 2001). However, the only consequence is that his checked bags will be held off the plane until it is confirmed that he has boarded. [9/11 Commission, 7/24/2004, pp. 1; 9/11 Commission, 8/26/2004, pp. 2 ; CNN, 3/3/2006] Noting that their flight is soon due to leave, the ticket agent who checks them in, Michael Tuohey, says, “You’re cutting it close.” [Portland Press Herald, 3/6/2005] Tuohey thinks the pair seems unusual. He notices they both have $2,500 first-class, one-way tickets. He later comments, “You don’t see many of those.” Atta looks “like a walking corpse. He looked so angry.” In contrast, Tuohey will say, Alomari can barely speak English and has “a goofy smile, I can’t believe he knew he was going to die that day.” Tuohey will later recount, “I thought they looked like two Arab terrorists but then I berated myself for the stereotype and did nothing.” [Philadelphia Daily News, 2/24/2005; Mirror, 9/11/2005; CNN, 3/3/2006] Atta becomes angry when Tuohey informs him he will have to check in again in Boston. He complains that he was assured he would have a “one-step check-in.” [9/11 Commission, 8/26/2004, pp. 2 ; Associated Press, 3/7/2005] Tuohey will be recalled to work later in the day to speak to an FBI agent about his encounter with Atta and Alomari. He is shown video footage of them passing through the airport’s security checkpoint upstairs (see (Between 5:45 a.m. and 5:53 a.m.) September 11, 2001). Although recognizing the two men, he notices that in the video they are no longer wearing the jackets and ties they’d had on when checking in just minutes before. He assumes they must have taken these off and tucked them into their carry-on baggage. He is also informed that the security camera behind his own desk, which should have captured the two hijackers, has in fact been out of order for some time. [Portland Press Herald, 3/6/2005; CNN, 3/3/2006]

Note the different times on the two time stamps, one in the middle, one at the bottom. [Source: FBI]Minutes after arriving at the Portland airport, hijackers Mohamed Atta and Abdulaziz Alomari pass through the airport’s single security checkpoint, on the way to boarding their 6 a.m. flight to Boston. The checkpoint has a surveillance camera pointing at it, which captures them as they go through. [Time, 9/24/2001; 9/11 Commission, 8/26/2004, pp. 2-3 ] Some reports say the pair passes through at 5:53 a.m. [Associated Press, 9/14/2001; New York Times, 9/14/2001; Washington Post, 9/14/2001] Other reports put it earlier, at 5:45 a.m. [Portland Press Herald, 10/5/2001; Federal Bureau of Investigation, 10/5/2001; 9/11 Commission, 8/26/2004, pp. 3 ] Strangely, when stills from the surveillance camera are later publicly released, they show two time stamps, one of 5:45 and another of 5:53. [Guardian, 9/21/2001; Federal Bureau of Investigation, 10/4/2001] When they’d checked in just minutes earlier, Atta and Alomari were observed wearing ties and jackets (see 5:43 a.m. September 11, 2001). But in the security video footage, they have just open-necked shirts, with no jackets or ties. [Philadelphia Daily News, 2/24/2005; Portland Press Herald, 3/6/2005; CNN, 3/3/2006]

9/11 hijackers Mohamed Atta and Abdulaziz Alomari’s flight from Portland to Boston takes off. [Federal Bureau of Investigation, 10/4/2001] Their plane, Colgan Air Flight 5930, is a 19-seat Beechcraft 1900. [Federal Bureau of Investigation, 2001; 9/11 Commission, 8/26/2004, pp. 3 ] Fellow passengers Vincent Meisner and Roger Quirion will later say Atta and Alomari board separately, keep quiet, and do not draw attention to themselves. [Chicago Sun-Times, 9/16/2001; Washington Post, 9/16/2001] Quirion, says: “They struck me as business travelers. They were sitting down, talking, seems like they were going over some paperwork.” [CBS News, 10/12/2001]

National Security Adviser Condoleezza Rice arrives at her office at the White House. [Bumiller, 2007, pp. xi] Rice will later recall that today is intended to be “a normal day, foreign visitors, several meetings.” [MSNBC, 9/11/2002] Usually she or her deputy, Stephen Hadley, goes along on presidential trips to handle any national security questions that might come up, so one of them would have gone with President Bush the previous day for his two-day trip to Florida (see September 10, 2001). [Dallas Morning News, 9/9/2001; Bumiller, 2007, pp. xi] But, as Rice will later recall, Bush’s trip is “such a short trip that we decided not to do that.” [MSNBC, 9/11/2002] In their place, they have sent Navy Captain Deborah Loewer, the director of the White House Situation Room. [Bumiller, 2007, pp. xi]

Odigo’s logo. [Source: Odigo]Two employees of Odigo, Inc., an Israeli company, receive warnings of an imminent attack in New York City about two hours before the first plane hits the WTC. Odigo, one of the world’s largest instant messaging companies, has its headquarters two blocks from the WTC. The Odigo Research and Development offices where the warnings were received are located in Herzliyya, a suburb of Tel Aviv. Israeli security and the FBI were notified immediately after the 9/11 attacks began. The two employees claim not to know who sent the warnings. “Odigo service includes a feature called People Finder that allows users to seek out and contact others based on certain interests or demographics. [Alex] Diamandis [Odigo vice president of sales and marketing] said it was possible that the attack warning was broadcast to other Odigo members, but the company has not received reports of other recipients of the message.” [Ha'aretz, 9/26/2001; Washington Post, 9/27/2001] Odigo claims the warning did not specifically mention the WTC, but the company refuses to divulge what was specified, claiming, “Providing more details would only lead to more conjecture.” [Washington Post, 9/28/2001] However, a later newspaper report claims that the message declared “that some sort of attack was about to take place. The notes ended with an anti-Semitic slur. ‘The messages said something big was going to happen in a certain amount of time, and it did—almost to the minute,’ said Alex Diamandis, vice president of sales for the high-tech company… He said the employees did not know the person who sent the message, but they traced it to a computer address and have given that information to the FBI.” [Washington Post, 10/4/2001] Odigo gave the FBI the Internet address of the message’s sender so the name of the sender could be found. [Deutsche Presse-Agentur (Hamburg), 9/26/2001] Two months later, it is reported that the FBI is still investigating the matter, but there have been no reports since. [Courier Mail, 11/20/2001]

President Bush has just spent the night at the Colony Beach and Tennis Resort on Longboat Key, Florida. [Sarasota Herald-Tribune, 9/10/2002] He wakes up around 6:00 a.m. and is preparing for his morning jog. [New York Times, 9/16/2001; Daily Telegraph, 12/16/2001; MSNBC, 10/27/2002] A van occupied by men of Middle Eastern descent arrives at the Colony Beach Resort, stating they have a “poolside” interview with the president. They do not have an appointment and are turned away. [Longboat Observer, 9/26/2001] Some question whether this was an assassination attempt modeled on the one used on Afghan leader Ahmed Massoud two days earlier (see September 9, 2001). [Time, 8/4/2002] Longboat Key Fire Marshal Carroll Mooneyhan was reported to have overheard the conversation between the men and the Secret Service, but he later denies the report. The newspaper that reported this, the Longboat Observer stands by its story. [St. Petersburg Times, 7/4/2004] Witnesses recall seeing Mohamed Atta in the Longboat Key Holiday Inn a short distance from where Bush was staying as recently as September 7, the day Bush’s Sarasota appearance was publicly announced (see September 7, 2001). [Longboat Observer, 11/21/2001; St. Petersburg Times, 7/4/2004]

All the alleged 9/11 hijackers reportedly check in at the airports from where they board Flights 11, 175, 77, and 93. [9/11 Commission, 7/24/2004, pp. 1-4; 9/11 Commission, 8/26/2004, pp. 27, 89, 93 ] Since 1998, the FAA has required air carriers to implement a program called the Computer Assisted Passenger Prescreening System (CAPPS). This identifies those passengers who might be a security risk, based upon suspicious behavior such as buying one-way tickets or paying with cash. CAPPS also randomly assigns some passengers to receive additional security scrutiny. If a particular passenger has been designated as a “selectee,” this information is transmitted to the airport’s check-in counter, where a code is printed on their boarding pass. At the airport’s security checkpoints, selectees are subjected to additional security measures. [US News and World Report, 4/1/2002; 9/11 Commission, 1/27/2004; US Congress, 3/17/2004; 9/11 Commission, 8/26/2004, pp. 2, 85 ] Their baggage is to be screened for explosives or held off the plane until they have boarded. Supposedly, the thinking behind this is that someone smuggling a bomb onto a plane won’t get onto that same flight. According to the 9/11 Commission, nine of the 19 hijackers are flagged by the CAPPS system before boarding Flights 11, 175, 77, and 93. [Washington Post, 1/28/2004; 9/11 Commission, 7/24/2004, pp. 84; United States of America v. Zacarias Moussaoui, a/k/a Shaqil, a/k/a Abu Khalid al Sahrawi, Defendant, 3/6/2006] In addition, Mohamed Atta was selected when he checked in at the airport in Portland, for his earlier connecting flight to Boston (see 5:33 a.m.-5:40 a.m. September 11, 2001). All of the hijackers subsequently pass through security checkpoints before boarding their flights. [9/11 Commission, 7/24/2004, pp. 1-4]

All five Flight 175 hijackers reportedly check in at Boston’s Logan Airport, pass through a security checkpoint, and board their plane during this period. The five hijackers are Marwan Alshehhi, Fayez Ahmed Banihammad, Hamza Alghamdi, Ahmed Alghamdi, and Mohand Alshehri. [9/11 Commission, 8/26/2004, pp. 89 ] The FAA has a program in place called CAPPS, which selects passengers for more thorough security screening based on suspicious behavior such as buying a one-way ticket or paying with cash (see (6:20 a.m.-7:48 a.m.) September 11, 2001). Although reports claim that between two and five of the Flight 175 hijackers have one-way tickets, none are selected by CAPPS. [WorldNetDaily, 4/24/2002; US Congress, 9/26/2002; US Congress, 9/26/2002; Washington Post, 1/28/2004; 9/11 Commission, 8/26/2004, pp. 18 ] Two of them have problems answering security questions at the ticket counter (see (6:20 a.m.-6:53 a.m.) September 11, 2001). At the security checkpoint, all five would pass through a walk-through metal detector, and an X-ray machine would screen their carry-on luggage. But Logan Airport has no video surveillance of its checkpoints (see 1991-2000), so there is no documentary evidence of exactly when they go through, or how they are processed. Jennifer Gore, the young supervisor overseeing the checkpoint, is later unable to recall seeing any of them. The Globe and Mail will explain, “[S]he was trained to look for metal bits in bags and in clothes, not people.” [Globe and Mail, 9/7/2002; 9/11 Commission, 7/24/2004, pp. 2; 9/11 Commission, 8/26/2004, pp. 18 ]

Two of the Flight 175 hijackers approach a customer service representative at the United Airlines ticket counter at Boston’s Logan Airport. The two appear unaccustomed to traveling. One tells the representative, Gail Jawahir, that he needs a ticket, though upon examining his documents she finds he already has one. Both men have problems answering standard security questions, which Jawahir has to repeat very slowly until they give the routine, reassuring answers. There is conflicting evidence over their identities. Jawahir will place her encounter with the men at “shortly before 7 a.m.” Shown photos of the alleged hijackers after 9/11, she will indicate that one of the two she encountered resembled Mohand Alshehri, suggesting the two were Alshehri and Fayez Ahmed Banihammad, who checked in at 6:53 a.m. Yet she recalls the two having the same last name and having assigned seats on Row 9 of the plane, suggesting they were Ahmed and Hamza Alghamdi, who checked in at 6:20 a.m. [9/11 Commission, 7/24/2004, pp. 2, 451; 9/11 Commission, 8/26/2004, pp. 17-18, 89 ]

John Sherman (left) and Rob Hargis (right). [Source: T.J. Kirkpatrick / MCT]A spontaneous training exercise is held in the White House Situation Room, based on the scenario of a terrorist bombing in Yemen. In recent months, the Situation Room has been extra vigilant due to the increased reporting of a possible terrorist attack on US interests in the Middle East. Presumably influenced by these concerns, Rob Hargis, the senior duty officer in the Situation Room, now holds an impromptu drill. He says to the others in the room: “Okay, there’s been a large bombing in Yemen. Who does what?” Further details of the exercise are unknown. Commenting on it, John Sherman, one of Hargis’s two assistants, will later say: “We were pretty keen on recognizing an event early. But we had no thoughts that morning about an attack on the homeland.”
Situation Room Is the 'Nerve Center' of Crisis Management - The Situation Room is a multi-room facility on the ground floor of the White House’s West Wing. It is staffed around the clock by personnel from each military branch, the State Department, and the intelligence agencies. [McClatchy Newspapers, 8/29/2011] Its mission is to provide current intelligence and crisis support to the National Security Council staff, the national security adviser, and the president. Its watch teams provide 24-hour monitoring of international events. [Studies in Intelligence, 1997] Throughout the terrorist attacks later this morning, the White House Situation Room will serve as “the nerve center of presidential crisis management,” according to McClatchy Newspapers. However, its director, Navy Captain Deborah Loewer, is away from the White House on this day, accompanying President Bush on his visit to Florida. [McClatchy Newspapers, 8/29/2011]

Sergeant Matt Rosenberg, an army medic at the Pentagon, is studying “a new medical emergency disaster plan based on the unlikely scenario of an airplane crashing into the place.” [Washington Post, 9/16/2001] The day before, Rosenberg later recalls in an interview with the Office of Medical History, he called the FBI with questions about who would have medical jurisdiction if such an event were to take place. “Believe it or not, the day prior to the incident, I was just on the phone with the FBI, and we were talking ‘so who has command should this happen, who has the medical jurisdiction, who does this, who does that,’ and we talked about it and talked about it, and he helped me out a lot. And then the next day, during the incident, I actually found him. He was out there on the incident that day.” [Office of Medical History, 9/2004, pp. 9]

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

The Joint Surveillance System (JSS). [Source: Dr. Steven R. Bussolari, MIT Lincoln Laboratory]Military radar in Massachusetts, which is used by NORAD’s Northeast Air Defense Sector (NEADS), is out of use this morning in order to undergo maintenance work. [9/11 Commission, 10/27/2003 ; 9/11 Commission, 10/27/2003 ]
Radar Scheduled to Go Down - The J53 radar in North Truro, Massachusetts, is one of a number of radar sites that NEADS receives data from. [United States Space Command, 12/30/1995; Jane's C4I Systems, 9/1/2005; North American Aerospace Defense Command, 10/23/2006 ] It has a range of 250 miles. According to Technical Sergeant Jeffrey Richmond, the assistant air surveillance technician at NEADS, J53 is scheduled to go down this morning for some major repairs to be carried out. [9/11 Commission, 10/27/2003 ; 9/11 Commission, 10/27/2003 ]
NEADS Personnel Refer to Radar - A member of staff at NEADS apparently refers to the J53 radar being offline shortly after those on the NEADS operations floor learn of the Flight 11 hijacking (see (8:38 a.m.) September 11, 2001) and while they are trying to locate the hijacked aircraft. She mentions that NEADS technicians “still should be able to get it” (presumably referring to the plane’s radar track) “without 53.” [North American Aerospace Defense Command, 9/11/2001] (According to Richmond, the area covered by J53 is overlapped by other radars, “so the need for radar to undergo routine maintenance is accounted for.”) ID technician Shelley Watson will later recall that the NEADS ID desk uses the J53 radar as a point from which it attempts to locate Flight 11. At some time during the morning, Richmond insists that J53 be put back online at some capacity. Whether this happens is unstated. [9/11 Commission, 10/27/2003 ; 9/11 Commission, 10/27/2003 ]
Radar Part of 'Joint Surveillance System' - The J53 radar site is part of the Joint Surveillance System (JSS). [Transportation Safety Board of Canada, 9/2/1998; US Department of the Air Force, 11/1/1999 ; 9/11 Commission, 2004] The JSS consists of “long-range radar sites around the perimeter of the US, with data shared by the [Department of Defense], FAA, Customs, and others.” A 2003 Department of Defense report will state that, at the time of the 9/11 attacks, US air defense relies “largely on outward looking ground-based radars, specifically, the Joint Surveillance System.” [US Department of Defense, 7/2003 ] According to General Ralph Eberhart, the commander of NORAD, NORAD has access to the JSS, “which is that system that rings the United States and looks out.” He will say this system “looks for that foreign threat. It looks for someone coming into our airspace that’s not authorized.” [US Congress. Senate. Armed Services Committee, 10/25/2001]

the Portland-Boston flight used by 9/11 hijackers Mohamed Atta and Abdulaziz Alomari arrives on time at Boston’s Logan Airport. [Der Spiegel, 2002] They cross a parking lot on their way to the departure terminal for Flight 11, and are observed asking for directions. The other three Flight 11 hijackers arrive at Logan in a rented car around this same time (see (6:45 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 5 ]

Flight 11 hijackers Waleed Alshehri, Wail Alshehri, and Satam Al Suqami arrive at Boston’s Logan Airport in a rental car, which they park in the airport’s central parking lot. [9/11 Commission, 8/26/2004, pp. 5 ] An unidentified man who arrives at Logan Airport at “about 6:30 a.m.” for an early flight has an argument with several Middle Eastern men over a parking space, before moving on, according to the News of the World. Some early press reports will say his confrontation is with five men. [Boston Herald, 9/12/2001; Daily Telegraph, 9/13/2001; ABC News, 9/14/2001; News of the World, 9/16/2001] However, the 9/11 Commission will later describe the incident differently. It will say there are just three Middle Eastern men, and the man ends up parked next to them. One of the Middle Eastern men opens his car door to get out and then spends time “fiddling with his things,” thus trapping the man in his car. Eventually the man has to force his way out, but the Middle Eastern men are completely unresponsive to him, saying nothing. The man will report the incident to authorities after hearing of the attacks. However, whether he identifies the men as Flight 11 hijackers is unstated. The hijackers’ car, which is associated with either Wail or Waleed Alshehri, will be found in the lot later in the day of 9/11. [9/11 Commission, 8/26/2004, pp. 85 ] Authorities will find Arabic-language flight training manuals inside the Mitsubishi rental. [Associated Press, 9/12/2001; Boston Herald, 9/12/2001; Daily Telegraph, 9/13/2001]

About an hour before boarding Flight 93, 9/11 hijacker Ziad Jarrah phones his girlfriend, Aysel Senguen, who is currently recovering from a minor operation in a hospital in Germany, where she lives. [Los Angeles Times, 10/23/2001; Observer, 8/22/2004] Senguen will later recount, “[H]e was very brief. He said he loved me three times. I asked what was up. He hung up shortly afterwards.… It was so short and rather strange him saying that repeatedly.” [Reuters, 11/19/2002; Guardian, 11/20/2002] Some accounts say Jarrah makes this call from his hotel, the Days Inn in Newark. Other accounts claim he makes it from a payphone at the airport, although he does not actually check in there until later on, at 7:39 a.m. [PBS, 1/17/2002; 9/11 Commission, 7/24/2004, pp. 532; Observer, 8/22/2004; Sunday Herald (Glasgow), 8/22/2004; 9/11 Commission, 8/26/2004, pp. 35 ]

During this period, all five Flight 11 hijackers check in at Boston’s Logan Airport and board their plane, bound for Los Angeles. The FAA has a program in place called the Computer Assisted Passenger Prescreening System (CAPPS), which is designed to identify those passengers most likely requiring additional scrutiny by airport security (see (6:20 a.m.-7:48 a.m.) September 11, 2001). Ticket records will show that CAPPS selects three of the Flight 11 hijackers at Logan: Since Waleed Alshehri checks no bags his selection has no consequences; Wail Alshehri and Satam Al Suqami have their bags scanned for explosives, but are not stopped. All five hijackers would need to pass through a security checkpoint to reach the departure gate for their flight. Each would have been screened as they walked through a metal detector calibrated to detect items with at least the metal content of a small-caliber handgun. If they’d set this off, they would have been screened with a handheld metal detector. An X-ray machine would have screened their carry-on luggage. However, Logan Airport has no video surveillance of its security checkpoints (see 1991-2000), so there is no documentary evidence of exactly when they pass through them, or if alarms are triggered. According to the 9/11 Commission, none of the checkpoint supervisors later recall seeing any of the Flights 11 hijackers, or report anything suspicious having occurred. [9/11 Commission, 1/27/2004; 9/11 Commission, 7/24/2004, pp. 1-2; 9/11 Commission, 8/26/2004, pp. 5-6 ] However, a WorldNetDaily article will claim that some Logan staff members recall seeing Mohamed Atta (see (6:50 a.m.-7:40 a.m.) September 11, 2001). [WorldNetDaily, 9/21/2001] The Boston Globe will later comment, “aviation specialists have said it is unlikely that more rigorous attention to existing rules would have thwarted the 10 hijackers who boarded two jets at Logan on Sept. 11. At the time, the knives and box-cutters they were carrying were permitted.” [Boston Globe, 10/17/2001]

According to later reports, the alarm system in WTC 7 is placed on “TEST” status for a period due to last eight hours. This ordinarily happens during maintenance or other testing, and any alarms received from the building are generally ignored. [National Institute of Standards and Technology, 6/2004, pp. 28 ]

According to an article on the conservative news website WorldNetDaily, alleged lead 9/11 hijacker Mohamed Atta almost misses Flight 11 and has to rush to the departure gate at Boston’s Logan Airport. The article is based on the account of an unnamed American Airlines employee at Logan, and claims Atta is running late because his connecting flight from Portland was delayed (see (6:00 a.m.) September 11, 2001). However, the 9/11 Commission claims that this plane was “on time,” and says Atta is observed at Logan with Abdulaziz Alomari, asking for directions in a parking lot (see 6:45 a.m. September 11, 2001). The employee says that at the baggage check-in, when asked security questions, Atta claims he does not speak English. A supervisor is called for, who just sends him towards the departure gate, as it is close to his plane’s take-off time. Atta rushes through the security checkpoint, then down to the gate, where he shows up perspiring. The employee comments, “The nitwit. You know, they’d been planning it for five years, and he’s running late for the flight.” An American Airlines spokeswoman will refuse to comment on this account, saying all American employees have been ordered not to speak to the press. [WorldNetDaily, 9/21/2001; 9/11 Commission, 8/26/2004, pp. 3, 5 ]

A three-minute call is made from a payphone at Boston’s Logan Airport, in the gate area from where Flight 175 will later depart, to 9/11 hijacker Mohamed Atta’s cell phone. The 9/11 Commission will report, “We presume Shehhi [i.e., hijacker Marwan Alshehhi] made the call, but we cannot be sure.” According to the commission, this is Atta and Alshehhi’s final conversation. [9/11 Commission, 7/24/2004, pp. 1, 451; 9/11 Commission, 8/26/2004, pp. 4 ] According to other reports, though, they later speak again briefly by cellphone while waiting for their planes to take off (see (Before 7:59 a.m.) September 11, 2001). [New York Times, 11/4/2001; Time, 8/4/2002]

The Vice President’s Residence. [Source: David Bohrer/ White House]Just before 7:00 a.m., Vice President Dick Cheney sits in the library of the vice president’s residence at the Naval Observatory in Washington, DC, for his regular CIA briefing. His solo briefing is more detailed than the president’s because he asks for more material. According to journalist and author Stephen Hayes, the briefing is “unremarkable.” Cheney typically sets off for the three-mile drive to the White House at 7:30 a.m. He usually joins the president for his intelligence briefing, but with Bush away in Florida, there is no briefing at the White House on this day. [Hayes, 2007, pp. 327-328] According to David Kuo, a special assistant to the president, Cheney arrives at the White House at just after 7:00 a.m. this morning. Kuo will later recall that Cheney “looked like an absentminded professor, deep in thought, oblivious to the world.” [Kuo, 2006, pp. 183]

New York City’s Emergency Operations Center (EOC) set up at Pier 92 on the Hudson River following the 9/11 attacks. [Source: ArcNews]At Pier 92 on the Hudson River, preparations are underway for a training exercise due to take place there the following day. The exercise, called Tripod, which had been scheduled months earlier, is intended to test how well New York’s Office of Emergency Management (OEM) can administer treatment in response to a biological-terrorism attack (see September 12, 2001). [New York Magazine, 10/15/2001; Giuliani, 2002, pp. 355] Pier 92, located just over four miles north-northwest of the World Trade Center, has been set up as a model distribution station where the simulated victims will be treated. [Jenkins and Edwards-Winslow, 9/2003, pp. 15 and 20] Ken Longert, the owner of a theatrical lighting business, arrives at the pier at 7:00 a.m. to help get the place ready for the exercise. He will later recall, “Two or three hundred cadets [presumably with the New York police and fire departments] were there, learning the proper procedures in case some kind of disaster hit New York.” Longert will recall that, seconds after the second WTC tower is hit at 9:03, “all the people from OEM disappeared” from the pier. [DiMarco, 2007, pp. 457-458] After OEM’s original command center is destroyed when WTC 7—where it is located—collapses (see (5:20 p.m.) September 11, 2001), Pier 92 will be selected as the location for the substitute command center. [9/11 Commission, 5/19/2004] Members of OEM staff have also arrived early this morning at the OEM offices in WTC 7 to prepare for the exercise (see 8:48 a.m. September 11, 2001). [Jenkins and Edwards-Winslow, 9/2003, pp. 15]

According to the 9/11 Commission, between 7:03 a.m. and 7:39 a.m. the four alleged Flight 93 hijackers check in at the United Airlines ticket counter at Newark (New Jersey) Liberty International Airport. Only Ahmad Alhaznawi is selected for additional scrutiny by airport security under the FAA’s CAPPS program (see (6:20 a.m.-7:48 a.m.) September 11, 2001). The only consequence is that his checked bag is screened for explosives, and not loaded onto the plane until it is confirmed that he has boarded. [9/11 Commission, 1/27/2004; 9/11 Commission, 7/24/2004, pp. 4; 9/11 Commission, 8/26/2004, pp. 35 ] On their way to boarding the plane, all four would pass through a security checkpoint, which has three walk-through metal detectors, two X-ray machines, and explosive trace detection equipment. [9/11 Commission, 8/26/2004, pp. 97 ] The 9/11 Commission later claims Newark Airport has no video cameras monitoring its security checkpoints, so there is no documentary evidence showing when the hijackers passed through the checkpoint or what alarms may have been triggered. [9/11 Commission, 7/24/2004, pp. 4; 9/11 Commission, 8/26/2004, pp. 35 ] However, Michael Taylor, the president of a security company, who has done consulting work for the New York Port Authority (which operates the airport), claims that Newark does use security cameras at the time of 9/11. [Boston Herald, 9/29/2001] All of the screeners on duty at the checkpoint are subsequently interviewed, and none report anything unusual or suspicious having occurred. [9/11 Commission, 7/24/2004, pp. 4; 9/11 Commission, 8/26/2004, pp. 35 ] The 9/11 Commission later concludes that the passports of Ahmad Alhaznawi and fellow Flight 93 hijacker Ahmed Alnami have suspicious indicators and could have been linked to al-Qaeda, but it does not elaborate on this.

Hijackers in a Dulles Airport, Washington, security checkpoint, from left to right: Nawaf Alhazmi gets searched, Khalid Almihdhar, and Hani Hanjour. [Source: FBI] (click image to enlarge)Around 7:15 a.m., Flight 77 hijackers Majed Moqed and Khalid Almihdhar check in at the American Airlines ticket counter at Washington’s Dulles International Airport. [9/11 Commission, 7/24/2004, pp. 2-3; 9/11 Commission, 8/26/2004, pp. 27 ] The FAA has a computer system in place, called CAPPS, which identifies those passengers most likely requiring additional scrutiny by airport security (see (6:20 a.m.-7:48 a.m.) September 11, 2001). CAPPS selects both men, but the only consequence is that Moqed’s luggage is not loaded onto Flight 77 until after his boarding is confirmed. [9/11 Commission, 1/27/2004; 9/11 Commission, 8/26/2004, pp. 27-28 ] Dulles Airport has surveillance cameras monitoring its security checkpoints, and video later viewed by the 9/11 Commission shows the two passing through the Main Terminal’s west security screening checkpoint at 7:18 a.m. When they go through, their carry-on bags fail to set off any alarms, but both men set off the alarm when they pass through the first metal detector. They are directed to a second metal detector, where Almihdhar passes, but Moqed fails again. He is subjected to a personal screening with a metal detection hand wand. This time he is cleared and permitted to pass through the checkpoint. [9/11 Commission, 1/27/2004; 9/11 Commission, 7/24/2004, pp. 3] The other three Flight 77 hijackers pass through the security checkpoint about 20 minutes later (see (7:25 a.m.-7:36 a.m.) September 11, 2001). The 9/11 Commission later concludes that Almihdhar’s passport was “suspicious” and could have been linked to al-Qaeda, but it does not explain why or how. [Baltimore Sun, 1/27/2004]

The specially modified C-135 nicknamed ‘Speckled Trout.’ [Source: United States Air Force]General Henry Shelton, the chairman of the Joint Chiefs of Staff, takes off to fly to Europe for a NATO conference, and will therefore be away from the US when the 9/11 terrorist attacks occur. [Giesemann, 2008, pp. 20, 22; Shelton, Levinson, and McConnell, 2010, pp. 430-433] Shelton is scheduled to attend a meeting of the Military Committee—NATO’s highest military authority—in Budapest, Hungary, on September 12, to discuss the situation in the Balkans, the European Security and Defense Identity, and NATO’s new force structure. On his return journey, he is set to stop in London, Britain, to be knighted by the Queen. [North Atlantic Treaty Organization, 9/10/2001; North Atlantic Treaty Organization, 9/11/2001; Shelton, Levinson, and McConnell, 2010, pp. 430] Shelton takes off from Andrews Air Force Base, just outside Washington, DC, on a specially modified C-135 (the military version of a Boeing 707) nicknamed “Speckled Trout.” Normally he flies on a VIP Boeing 757 often used by the vice president, but that aircraft is presently unavailable, so he is flying instead on the C-135, which is usually reserved for the Air Force chief of staff. Those accompanying Shelton on the flight include his wife, Carolyn; his executive assistant, Colonel Doug Lute; his aides, Master Sergeant Mark Jones and Lieutenant Commander Suzanne Giesemann; and his personal security agent, Chief Warrant Officer Marshall McCants. [Giesemann, 2008, pp. 20-22; Shelton, Levinson, and McConnell, 2010, pp. 431, 434] When Shelton is out of the country, General Richard Myers, the vice chairman of the Joint Chiefs of Staff, is designated by law as acting chairman of the Joint Chiefs of Staff in his place. Shelton will later recall, “Until I crossed back into United States airspace, all the decisions would be [Myers’s] to make, in conjunction with Secretary [of Defense Donald] Rumsfeld and the president.” [Myers, 2009, pp. 10; Shelton, Levinson, and McConnell, 2010, pp. 432] After learning of the attacks in New York, Shelton will give the order for his plane to return to the US (see (8:50 a.m.-10:00 a.m.) September 11, 2001). [Giesemann, 2008, pp. 22-23; Shelton, Levinson, and McConnell, 2010, pp. 431] However, he will only arrive at the National Military Command Center at the Pentagon very late in the afternoon (see 5:40 p.m. September 11, 2001). [Myers, 2009, pp. 159]

Hijacker brothers Salem (white shirt) and Nawaf Alhazmi (dark shirt) pass through security in Dulles Airport in Washington. [Source: FBI] (click image to enlarge)Flight 77 hijacker Hani Hanjour checks in at the American Airlines ticket counter at Washington’s Dulles International Airport some time between 7:25 a.m. and 7:35 a.m., the 9/11 Commission will later estimate. (American Airlines will be unable to locate information confirming his check-in time.) [9/11 Commission, 8/26/2004, pp. 93 ]
Hanjour Almost Stopped? - Hanjour is selected for additional scrutiny by airport security under the FAA’s CAPPS program (see (6:20 a.m.-7:48 a.m.) September 11, 2001), but this has no consequences. [9/11 Commission, 1/27/2004; 9/11 Commission, 7/24/2004, pp. 3; 9/11 Commission, 8/26/2004, pp. 27-28 ] In 2003, former CIA official Vincent Cannistraro will claim: “This person goes through the metal detection machine and it starts buzzing.… They call the person out so that they can do a hand search. Just as the person was beginning to do that, a pretty woman walks by and the guard looks at her and waves the guy on. Well, that person happened to be Hani Hanjour, and he basically had box cutters and razor blades in his pockets.” [Fouda and Fielding, 2003, pp. 143] It is unclear how Cannistraro may have known this, and presumably he is speculating as to what Hanjour has in his pockets.
Alhazmi Brothers Seem Suspicious - The final two Flight 77 hijackers, brothers Nawaf and Salem Alhazmi, check in at approximately 7:29 a.m. The customer service representative makes both of them CAPPS selectees, because one of them cannot provide photo identification and seems unable to understand English, and he finds both of them suspicious. However, the only consequence is that Salem Alhazmi’s luggage is not loaded onto the plane until it is confirmed that he has boarded. Surveillance cameras monitor the security checkpoints at Dulles Airport. According to the 9/11 Commission’s review of security footage, Hanjour passes through the main terminal’s west security screening checkpoint at 7:35 a.m. He proceeds through the metal detector without setting off the alarm, and his two carry-on bags set off no alarms when placed on the X-ray belt. The Alhazmis arrive at the same checkpoint a minute later. Salem Alhazmi successfully clears the metal detector and is permitted through the checkpoint. Nawaf Alhazmi sets off the alarms for both the first and second metal detectors, and is subsequently subjected to a personal screening with a metal detection hand wand before being passed. His shoulder bag is swiped by an explosive trace detector and returned without further inspection. [9/11 Commission, 1/27/2004; 9/11 Commission, 7/24/2004, pp. 3; 9/11 Commission, 8/26/2004, pp. 27-28 ] Immediately after the attacks, when the FAA’s local civil aviation security office investigates the security screening at Dulles on 9/11, it will find the airport’s screeners recall nothing out of the ordinary, and cannot recall any of the passengers they screened having been CAPPS selectees. [9/11 Commission, 7/24/2004, pp. 3; 9/11 Commission, 8/26/2004, pp. 93 ] The 9/11 Commission will later conclude that the Alhazmi brothers’ passports are “suspicious” and could have been linked to al-Qaeda, but it will not explain why or how. [Baltimore Sun, 1/27/2004]

American Airlines Flight 11 pushes back from the gate at Boston’s Logan Airport. [9/11 Commission, 7/24/2004, pp. 2] There are discrepancies over which gate it leaves from. Most early reports state that it pushes out from Gate 26 in Terminal B of the airport. [Boston Globe, 9/12/2001; Chicago Sun-Times, 9/13/2001; Daily Telegraph, 9/16/2001; Washington Post, 9/16/2001; Bernstein, 2002, pp. 179; Der Spiegel, 2002, pp. 36] However, one unnamed Logan Airport employee will say it leaves from Gate 32, also in Terminal B. [Boston Globe, 9/11/2001] The transcript of radio communications with the flight confirms it left from Gate 32, and the 9/11 Commission also later states this. [New York Times, 10/16/2001; 9/11 Commission, 7/24/2004, pp. 451] The reason for the discrepancy in these reports is unclear. Flight 11, a Boeing 767 with a capacity of 158 passengers, is about half full on this day, with 81 passengers on board (including the five hijackers), along with the two pilots and nine flight attendants. [9/11 Commission, 8/26/2004, pp. 6 ] It will take off at 7:59 (see (7:59 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 4]

Hijacker Mohamed Atta on Flight 11 calls hijacker Marwan Alshehhi in Flight 175 as both planes sit on the runway. They presumably confirm the plot is on. [Time, 8/4/2002]

9/11 hijackers Mohamed Atta and Abdulaziz Alomari board Flight 11. Atta’s bags are not loaded onto the plane in time and are later found by investigators. Investigators later find airline uniforms and many other remarkable items. [Boston Globe, 9/18/2001] It is later reported that at least two other hijackers on Flight 11 use stolen uniforms and IDs to board the plane. [Sunday Herald (Glasgow), 9/16/2001] It has not been explained why the hijackers would have bothered to get these uniforms only to put them in their checked-in baggage where they would not be able to access them.

Two passengers leave Flight 93 after hearing an announcement that there will be a five-minute delay in the plane pushing back from the gate. This is according to Terry Tyksinski, a longtime flight attendant with United Airlines, who says a customer service supervisor who witnessed the incident told her about it six months after 9/11. The two first-class passengers are reportedly of dark complexion, “kind of black, not black.” According to Tyksinski, the supervisor notes their names and is subsequently twice interviewed by the FBI. [Longman, 2002, pp. xiii-xiv] No other accounts, including the 9/11 Commission Report, mention this incident. [9/11 Commission, 7/24/2004] And while Flight 93 is delayed on the ground until 8:42 a.m., reports state that it pushes back from the gate just one minute later than its scheduled departure, rather than there being a five-minute delay as Tyksinski suggests. [Boston Globe, 11/23/2001; MSNBC, 9/11/2006] There will only be 37 passengers on Flight 93, including the four hijackers. This is 20 percent of the plane’s passenger capacity of 182 and, according to the 9/11 Commission, “is considerably below the 52 percent average load factor for Flight 93 for Tuesdays in the three-month period prior to September 11.” [9/11 Commission, 8/26/2004, pp. 36 ]

As well as the secretary of defense, others in attendance include Rumsfeld’s senior military assistant, Navy Vice Admiral Edmund Giambastiani Jr.; Deputy Defense Secretary Paul Wolfowitz; Pete Geren, a special assistant to Rumsfeld; and Representatives John Mica (R-FL), Mark Steven Kirk (R-IL), Mac Thornberry (R-TX), Roger Wicker (R-MS), Robin Hayes (R-NC), Doug Bereuter (R-NE), John Hostettler (R-IN), Kay Granger (R-TX), John Shimkus (R-IL), Randy “Duke” Cunningham (R-CA), and Christopher Cox (R-CA).

And as that breakfast was breaking up, the first plane had hit the World Trade tower.” [PBS Frontline, 10/26/2004; PBS, 10/26/2004] By “chairman of the Joint Chiefs of Staff,” White presumably means Richard Myers, who is the acting chairman on this day, in place of Henry Shelton who is out of the country (see 7:15 a.m. September 11, 2001). [American Forces Press Service, 9/8/2006] During the course of the meeting Rumsfeld predicts that some kind of “shocking” world event will occur in the near future (see (Before 8:46 a.m.) September 11, 2001). Most accounts suggest the meeting is adjourned soon after the time the first World Trade Center tower is hit, presumably around 8:50 a.m., though one report says it ends at about 9:00 a.m. Just prior to the meeting ending, Rumsfeld is handed a note informing him of the crash (see Shortly After 8:46 a.m. September 11, 2001). Giambastiani also sees this note. Whether the other people in attendance are notified of the crash at this time is unknown. [Larry King Live, 12/5/2001; US Department of Defense, 8/12/2002; PBS, 10/26/2004; American Forces Press Service, 9/8/2006] White will later recall, “We all went on with the day’s business,” after leaving the meeting. White heads off to give a speech at the nearby Army Navy Country Club. [PBS Frontline, 10/26/2004] Rumsfeld, Wolfowitz, and Giambastiani return to their offices.

A helicopter and its crew that are always on standby for “contingency” missions in the Washington area are away from base early this morning conducting a traffic survey, but apparently return at some point before the Pentagon is hit. The crew belongs to the 12th Aviation Battalion. [US Army Center for Military History, 11/14/2001 ; Army Center of Military History, 11/14/2001 ] The 12th Aviation Battalion is stationed at Davison Army Airfield at Fort Belvoir, located 12 miles south of the Pentagon. It is the aviation support unit for the Military District of Washington, and operates UH-1 “Huey” and UH-60 Black Hawk helicopters. [Military District of Washington, 8/2000] According to a chief warrant officer with the unit, the 12th Aviation Battalion has “two crews that are always on standby for any kind of contingency mission.” It is one of these crews that is “out flying around doing a traffic survey.” [Army Center of Military History, 11/14/2001 ] The exact time period during which the crew and their helicopter are away from base is unstated, but they apparently return to Davison Airfield before 9:37 a.m., when the Pentagon is hit (see Shortly Before 9:37 a.m. September 11, 2001). [US Army Center for Military History, 11/14/2001 ] They will be the first crew with the battalion to take off in support of the rescue operations at the Pentagon once the unit’s aircraft are permitted to launch again following the attack. Others members of the 12th Aviation Battalion are also away from base this morning, for weapons training (see 8:46 a.m.-9:37 a.m. September 11, 2001). [Army Center of Military History, 11/14/2001 ]

The daily threat briefing at NORAD’s Northeast Air Defense Sector (NEADS) includes no indication of any increase in the terrorist threat level. Lieutenant Colonel Mark Stuart, an intelligence officer working in the NEADS battle cab, will tell the 9/11 Commission that for his threat briefing today, there is “‘zero’ intelligence available concerning any increase in the terrorist threat level.” He will say that a briefing two days ago, on September 9, similarly “contained nothing on the terrorist threat.” Stuart will say the last briefing at NEADS that mentioned the threat posed by Osama bin Laden was on July 14, “as part of the increased threat warning during summer 2001.” [9/11 Commission, 10/30/2003 ; 9/11 Commission, 1/20/2004] NEADS, which is based in Rome, New York, will be responsible for coordinating the US military’s response to the hijackings later this morning (see 8:45 a.m. September 11, 2001 and 9:24 a.m. September 11, 2001). [Vanity Fair, 8/1/2006; Shenon, 2008, pp. 203]

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]

Jeff Ford. [Source: Thomas Doscher / US Air Force]Personnel in NORAD’s operations center in Cheyenne Mountain, Colorado, take part in a major Cold War-style training exercise called Vigilant Guardian, a war game in which the theoretical enemy is Russia. [9/11 Commission, 3/1/2004 ; Denver Post, 8/28/2011; Colorado Springs Gazette, 9/10/2011] All of NORAD, including its subordinate units (see (6:30 a.m.) September 11, 2001), participates in the exercise. [Northeast Air Defense Sector, 8/23/2001; Canadian Broadcasting Corporation, 9/8/2011] More than 50 people in the NORAD Battle Management Center in Cheyenne Mountain take part. [Airman, 3/2002; Defense Video and Imagery Distribution System, 9/8/2011] Vigilant Guardian is an annual exercise and is scheduled to last two weeks. [Arkin, 2005, pp. 545; Canadian Broadcasting Corporation, 9/8/2011] It has been underway for several days. Those in the Cheyenne Mountain Operations Center (CMOC) have been participating in it “for at least three or four days,” according to Lieutenant Colonel Steven Armstrong, NORAD’s chief of plans and forces. [North American Aerospace Defense Command, 9/9/2011]
Vigilant Guardian Is a 'Full-Blown Nuclear War' Exercise - Vigilant Guardian is a “transition to wartime operations command post exercise,” according to an information page for its participants. [Northeast Air Defense Sector, 8/23/2001] The 1st Air Force’s book about 9/11 will describe it as a “simulated air war.” [Filson, 2003, pp. 55] Lieutenant Colonel William Glover, the commander of NORAD’s Air Warning Center, will later recall that it involves NORAD “simulating war.… You know, attacks coming from the outside, Soviet-style bombers coming in, cruise-missile attacks, that type of thing.” [Canadian Broadcasting Corporation, 9/8/2011] Ken Merchant, NORAD’s joint exercise design manager, will tell the 9/11 Commission that Vigilant Guardian is a “full-blown nuclear war” exercise, and includes bomber response and intercontinental ballistic missile response. [9/11 Commission, 3/4/2004]
Russia Is Imagined Enemy - The theoretical enemy in the exercise is Russia. [Denver Post, 8/28/2011] According to the 9/11 Commission Report, the exercise “postulated a bomber attack from the former Soviet Union.” [9/11 Commission, 7/24/2004, pp. 458] Merchant will explain that “NORAD must use Russia in its exercises at the strategic level since no other country poses a great enough threat to NORAD’s capabilities and responsibilities.” [9/11 Commission, 3/4/2004]
Personnel Updated on Exercise during Shift Change - Armstrong will later recall that today starts off “like any other day. We came in thinking it would be a normal day… we did a standard shift changeover in the morning and we were getting right into where we were at in relation to the exercise.” He will describe that in a shift change during the exercise, “We’d say, ‘Okay, here’s what happened during the night shift (or the day shift),’ and we’d give each other an update, and then we’d start planning for whatever was on the agenda for that day.” [North American Aerospace Defense Command, 9/9/2011] According to the Denver Post, after commencing his shift, Armstrong “mapped out strategy in a chess game of ever-escalating scenarios, from strained diplomacy to the outbreak of conventional warfare that headed inexorably toward nuclear conflict” with Russia. [Denver Post, 8/28/2011]
B-1 Bomber Scheduled to Fly out over Pacific Ocean - The “planned big event for the day” in the exercise is “supposed to be a B-1 bomber that was flying out of Fairchild Air Force Base [in Washington State] and going out over the Pacific,” according to Jeff Ford, an Air Force lieutenant colonel who is working in the CMOC. Ford will add that there are “other things going on as part of the exercise, air exercise events, and then some scripted inputs that we were reacting to there in the Air Warning Center, whether it be unknown aircraft that we scramble aircraft for to intercept—or whatever.” [Defense Video and Imagery Distribution System, 9/8/2011]
Exercise Posture Allegedly Helps Response to Attacks - Vigilant Guardian will reportedly end after 9:03 a.m., when the second plane hits the World Trade Center (see (Shortly After 9:03 a.m.) September 11, 2001), and the CMOC personnel participating in it will then become involved in responding to the real-world attacks. [Airman, 3/2002; Toronto Star, 11/11/2008] Glover will claim that the CMOC’s response to the terrorist attacks benefits from the position the operations center is in for the exercise. He will say NORAD is “lucky” because “all the directorates such as operations, logistics, security, all those folks were up in the [Cheyenne] Mountain on an exercise posture.” He will add that “these are the same folks that we would bring up in case of contingencies or in time of going to war. So, in reality, I had all the guys up into the NORAD Battle Management Center that I needed to conduct the exercise as well as the contingency operations that happened on 9/11.” [Defense Video and Imagery Distribution System, 9/8/2011]
NORAD Monitoring Russian Exercise - NORAD was created in 1958, during the Cold War, to protect North American airspace against nuclear attacks from the Soviet Union. [New York Times, 4/25/2004; Canadian Broadcasting Corporation, 8/6/2004; Legion Magazine, 11/2004] According to the Toronto Star, “Whether it’s a simulation or a real-world event, the role of the [CMOC] is to fuse every critical piece of information NORAD has into a concise and crystalline snapshot.” [Toronto Star, 12/9/2001] As well as the Vigilant Guardian exercise, NORAD is currently in the middle of an operation called Northern Vigilance, with its fighter jets deployed to Alaska and Northern Canada to monitor an exercise being run by the Russian Air Force (see September 9, 2001). [North American Aerospace Defense Command, 9/9/2001] The battle staff members in Cheyenne Mountain are positioned to deal with both this operation and the exercise. [9/11 Commission, 3/1/2004 ]

Charlie Wells. [Source: Publicity photo]Having returned to the Colony Beach and Tennis Resort after his morning jog, President Bush meets for a brief chat in his penthouse suite with Manatee County Sheriff Charlie Wells, Sarasota County Sheriff Bill Balkwill, Sarasota Police Chief Gordon Jolly, and Manatee County Sheriff’s Colonel Ken Pearson. Wells later recalls the president was “totally unsuspecting about what is to happen.… It looked like, to me, he’s saying, ‘Glad to see you, but I’m ready to get on to the school and meet the kids.’” The four law enforcement officials will later travel to the Sarasota school in the president’s motorcade. [Sammon, 2002, pp. 36; Sarasota Herald-Tribune, 9/10/2002]

Brenton Greene. [Source: National Communications System]CIA representatives give a briefing to a little-known government agency called the National Communications System (NCS) at a facility just outside Washington, DC, where they discuss the threat that international terrorists pose to the US’s telecommunications infrastructure. The NCS is a relatively small agency that works to ensure the uninterrupted availability of critical communications networks during times of national crisis. It will play an important role in the response and recovery efforts following the terrorist attacks in New York and at the Pentagon, when damage to the World Trade Center area severely impairs the local telecommunications infrastructure. [Verton, 2003, pp. 135-137; National Communications System, 2004, pp. 56 ]
Briefing Attended by Public and Private Sectors Representatives - The briefing is held at what journalist and author Dan Verton will call “a secure facility outside of Washington, DC.” Presumably this is the NCS’s National Coordinating Center in Arlington, Virginia. Attendees include Brenton Greene, the director of the NCS since April 2001, and representatives from seven other federal agencies and over 40 technology and communications companies that operate many of the US’s most critical communications networks. The representatives from the private sector, according to Verton, are all “senior executives from their respective companies, and all had government security clearances that granted them access to the most sensitive intelligence data pertaining to threats to the infrastructures that formed not only the lifelines of their businesses but the lifelines of the nation as well.”
CIA Outlines Threat to Telecommunications Infrastructure - Although Greene is a 25-year veteran of the Navy’s submarine force and is “used to classified briefings and operating in the shadows,” the current briefing, according to Verton, promises “to be different from any other he had taken part in.” The CIA representatives begin it at 8:00 a.m. by outlining the growing international terrorist threat to the US telecommunications infrastructure.
Terrorists Aware of Benefits of Targeting Telecommunications - Verton will describe that the briefing participants then agree that there is “a growing body of evidence relating to the increased sophistication in information warfare (IW) capabilities of foreign nations.” Additionally, a cyber-attack against computer systems in the US “would likely involve a major disruption of key telecommunications infrastructures serving other sectors of the economy, including banking and finance, electric power, and air traffic control.” Greene will later comment: “Everything runs on telecom. If it’s a major cyber-event, it’s going to have a physical tail. If it’s a major physical event, it’s going to have a cyber-tail.” The CIA representatives say that some terrorist organizations are also becoming aware of the potential offered by targeting the telecommunications infrastructure.
Briefing Continues despite News of First Crash - Shortly after 8:46 a.m., when the first plane hits the WTC, Navy Captain J. Katharine Burton enters the briefing room and whispers to Greene the news of what has happened. With no further information available and no evidence that the crash was anything more than an accident, Greene calmly passes on the news to the other people in the room, and then orders the briefing to continue. The CIA representatives therefore go on until news arrives of the second plane hitting the WTC at 9:03 a.m., and televisions are turned on to CNN, which is showing live coverage from New York. Greene will later recall: “It was clear then that there was some threat. When the second plane hit, I said: ‘I’m leaving. I need to go look at the implications of this.’” [Verton, 2003, pp. 135-139, 141]
9/11 Attacks Are 'the Most Significant Challenge' to the NCS - The NCS will play a key role in the government’s response to the 9/11 attacks, which result in severe damage and impairment to the telecommunications infrastructure serving the area around the WTC. [National Communications System, 2004, pp. 56 ] Greene will later recall that the destruction caused by the attacks becomes “the most significant challenge that the National Communications System had ever seen.” [Verton, 2003, pp. 151] The NCS’s National Coordinating Center is activated, and supports response and recovery efforts (see (8:48 a.m.) September 11, 2001). After leaving the briefing, Greene will head to his “Continuity of Government” site, from where the status of the communications network is constantly monitored, and priorities and repairs are coordinated. [9/11 Commission, 3/16/2004 ]

Many aircraft at Andrews Air Force Base, which is just a few miles outside Washington, DC, are taking part in training exercises. James Ampey, an FAA air traffic controller who is currently on duty in the control tower at the base, will later recall that there are “an unusually high number of aircraft taking off and landing at Andrews [this] morning, because previously scheduled military exercises [are] underway.” [9/11 Commission, 7/28/2003 ] It is unclear what specific exercises these aircraft are participating in, and the exact time period Ampey is referring to.
Militarized 747 Involved in 'Global Guardian' Exercise - According to journalist and author Dan Verton, around the time of the Pentagon attack, “civilian and military officials [are] boarding a militarized version of a Boeing 747, known as the E-4B National Airborne Operations Center (NAOC), at an airfield outside of the nation’s capital. They [are] preparing to conduct a previously scheduled Defense Department exercise” (see (Shortly Before 9:37 a.m.) September 11, 2001). [Verton, 2003, pp. 143-144] This airfield could well be Andrews Air Force Base, which is just 10 miles from Washington. [GlobalSecurity (.org), 1/21/2006] The exercise being referred to is apparently the US Strategic Command’s annual exercise, Global Guardian, for which three E-4Bs are reportedly launched (see 8:30 a.m. September 11, 2001 and Before 9:00 a.m. September 11, 2001). [Omaha World-Herald, 2/27/2002; Omaha World-Herald, 9/8/2002] Whether other aircraft that are taking off or landing at Andrews are participating in Global Guardian is unknown.
NORAD Exercise, 'Vigilant Guardian' - Another major exercise taking place this morning is called Vigilant Guardian. All of the North American Aerospace Defense Command (NORAD) is participating in it (see (6:30 a.m.) September 11, 2001). [Newhouse News Service, 1/25/2002; Aviation Week and Space Technology, 6/3/2002] However, Andrews is not one of NORAD’s seven “alert” sites around the US. [Airman, 12/1999] And the 113th Wing of the District of Columbia Air National Guard, which is based at Andrews, is not part of the NORAD air defense force. [Aviation Week and Space Technology, 9/9/2002; Filson, 2003, pp. 76] Furthermore, members of the 113th Wing have just returned from a major training exercise in Nevada (see Late August-September 8, 2001), and so, with only a few pilots and planes available, today is a “light flying day” for their unit. [9/11 Commission, 3/11/2004 ] Presumably the 113th Wing is therefore not currently participating in Vigilant Guardian or any other major exercises.
Numerous Units at Andrews - There are, however, many units at Andrews that may be participating in exercises. Among more than 60 separate organizations located at the base are units from the Army, Navy, Marine Corps, Air Force Reserve, and Air National Guard. [DC Military (.com), 6/2001; GlobalSecurity (.org), 1/21/2006] These units include Marine Fighter Attack Squadron 321 (VMFA-321), which flies the F/A-18 Hornet fighter jet, and Naval Air Facility, Washington, DC, which has numerous aircraft available, including the F/A-18 Hornet. [DC Military (.com), 2/9/2001; DC Military (.com), 6/2001]
Andrews Units Respond to Attacks - DC Air National Guard fighters will later take off from Andrews to protect Washington in response to the morning’s attacks (see (10:38 a.m.) September 11, 2001, 10:42 a.m. September 11, 2001, and 11:11 a.m. September 11, 2001). [Aviation Week and Space Technology, 9/9/2002] And a member of VMFA-321 calls NORAD’s Northeast Air Defense Sector (NEADS) at around 9:50 a.m. to offer his unit’s assistance in response to the attacks (see (9:50 a.m.) September 11, 2001). [Spencer, 2008, pp. 188]

From left to right: Senator Bob Graham (D), Senator Jon Kyl (R), and Representative Porter Goss (R). [Source: US Senate, National Park Service, US House of Representatives]Around 8:00 a.m., on September 11, 2001, ISI Director Lt. Gen. Mahmood Ahmed is at a breakfast meeting at the Capitol with the chairmen of the House and Senate Intelligence Committees, Senator Bob Graham (D-FL) and Representative Porter Goss (R-FL), a 10-year veteran of the CIA’s clandestine operations wing. Also present at the meeting are Senator Jon Kyl (R-AZ) and the Pakistani ambassador to the US, Maleeha Lodhi, as well as other officials and aides. (Goss, Kyl, and Graham had just met with Pakistani President Pervez Mushrraf in Pakistan two weeks earlier (see August 28-30, 2001)). [Salon, 9/14/2001; Washington Post, 5/18/2002] Graham and Goss will later co-head the joint House-Senate investigation into the 9/11 attacks, which will focus on Saudi government involvement in the 9/11 attacks, but will say almost nothing about possible Pakistani government connections to al-Qaeda and the 9/11 attacks (see August 1-3, 2003 and December 11, 2002). [Washington Post, 7/11/2002] Note that Senator Graham should have been aware of a report made to his staff the previous month (see Early August 2001) that one of Mahmood’s subordinates had told a US undercover agent that the WTC would be destroyed. Some evidence suggests that Mahmood ordered that $100,000 be sent to hijacker Mohamed Atta (see October 7, 2001).
Pakistan's Demands - Graham will later say of the meeting: “We were talking about terrorism, specifically terrorism generated from Afghanistan.” The New York Times will report that bin Laden is specifically discussed. [Vero Beach Press Journal, 9/12/2001; Salon, 9/14/2001; New York Times, 6/3/2002] The US wants more support from Pakistan in its efforts to capture bin Laden. However, Mahmood says that unless the US lifts economic sanctions imposed on Pakistan and improves relations, Pakistan will not oppose the Taliban nor provide intelligence and military support to get bin Laden. He says, “If you need our help, you need to address our problems and lift US sanctions.” He also encourages the US to engage the Taliban diplomatically to get them to change, instead of isolating them. Pakistani journalist Ahmed Rashid will later comment, “It was absurd for Mahmood to insist now that the Americans engage with the Taliban, when [Pakistan’s] own influence over them was declining and al-Qaeda’s increasing.”
Meeting Interrupted by 9/11 Attacks - Zamir Akram, an accompanying Pakistani diplomat, leaves the room for a break. While outside, he sees a group of Congressional aides gathered around a television set. As Akram walks up to the TV, he sees the second plane crashing into the World Trade Center. He immediately runs back to the meeting to the tell the others. But even as he gets there, a congressional aide comes in to say that Capitol Hill is being evacuated. The aide says, “There is a plane headed this way.” Mahmood and the rest of the Pakistani delegation immediately leave and attempt to return to the Pakistani embassy. But they are stuck in traffic for three hours before they get there. [Rashid, 2008, pp. 26-27]

Former President George H. W. Bush, along with former First Lady Barbara Bush, leaves Washington, DC, by private jet, bound for a speaking engagement in St. Paul, Minnesota. The Bushes spent the previous night at the White House. They had flown to Washington the previous day to attend several meetings and a dinner. One of the meetings attended by the former president was the annual investor conference of the Carlyle Group, which was also attended by Shafig bin Laden, one of Osama bin Laden’s brothers (see (9:00 a.m.) September 11, 2001). They are later informed of the WTC attacks while on their jet. Due to all planes being grounded, they have to land in Milwaukee, Wisconsin. [CBS News, 11/1/2002; CNN, 10/25/2003; Newsweek, 10/27/2003]

An “emergency drill” has been scheduled for today, to take place on the 97th floor of the WTC South Tower. [New York Times, 3/31/2006; New York Times, 4/1/2006] A team of technology consultants from California is visiting investment firm Fiduciary Trust for this drill. (Fiduciary Trust has offices on the 97th floor.) [USA Today, 9/13/2001; Dwyer and Flynn, 2005, pp. 77; New York Times, 3/30/2006] No further details are reported as to what it entails, or who the technology consultants are. However, California-based software company Oracle Corp. will later report that six of its consultants were working on the 97th floor of the South Tower on 9/11 and are subsequently missing. So presumably these were the workers involved with the drill. [InfoWorld, 9/13/2001; Associated Press, 9/14/2001]

WTC leaseholder Larry Silverstein is supposed to be working today in the temporary offices of his company, Silverstein Properties, on the 88th floor of the North Tower. However, at his Park Avenue apartment, Silverstein’s wife reportedly “laid down the law: The developer could not cancel an appointment with his dermatologist, even to meet with tenants at his most important property.” [New York Observer, 3/17/2003; New York Magazine, 4/18/2005] He is therefore not at the WTC when it is hit, and first hears of the attacks when an associate calls him from the lobby of one of the WTC buildings. [Real Deal, 1/2004] Two of Silverstein’s children—his son, Roger, and daughter, Lisa—work for his company and have been regularly attending meetings with WTC tenants at Windows on the World (the restaurant at the top of the North Tower). Yet this morning they are running late. According to the New York Observer, “If the attack had happened just a little later, Mr. Silverstein’s children would likely have been trapped at Windows.” [New York Observer, 3/17/2003] Fifty-four of Silverstein Properties’ 160 staff are in the North Tower when it is hit, and four of them die. [Globe and Mail, 9/7/2002] Silverstein signed the lease on the WTC less than two months previously, and later will attempt to get $7 billion in insurance for the destruction of the towers (see July 24, 2001).

Just after 8 a.m., President Bush sits down at his hotel on Longboat Key, Florida, for his daily intelligence briefing with Mike Morell, his CIA briefer. They discuss developments in the Middle East, and particularly the Palestinian situation. According to the London Telegraph, “The president’s briefing appears to have included some reference to the heightened terrorist risk reported throughout the summer,” but it contains nothing serious enough to cause Bush to call National Security Adviser Rice, who is currently on her way from her home to her office at the White House. However, journalist and author Ronald Kessler will contradict this, claiming, “Bush placed a call to Condoleezza Rice and asked her to follow up on a few points.” The briefing ends by around 8:15 a.m. [Daily Telegraph, 12/16/2001; Kessler, 2004, pp. 136; Tenet, 2007, pp. 165]

Flight 93 is delayed for 41 minutes on the runway at Newark Airport, New Jersey. It will take off at 8:42 a.m. [Newsweek, 9/22/2001; Pittsburgh Post-Gazette, 10/28/2001; Boston Globe, 11/23/2001] Apparently, it has to wait in a line of about a dozen planes before it can take off. [USA Today, 8/11/2002] According to the Pittsburgh Post-Gazette, the delay is partly due to a fire at the airport the previous afternoon that had led to the runways being closed for 34 minutes. [CNN, 9/10/2001; Bergen Record, 9/11/2001; Pittsburgh Post-Gazette, 10/28/2001] But the 9/11 Commission says it is “because of the airport’s typically heavy morning traffic.” [9/11 Commission, 7/24/2004, pp. 10] And the Boston Globe later reports that United Airlines “will not explain why” Flight 93 was delayed on the runway. [Boston Globe, 11/23/2001] NBC News comments, “That delay would give passengers on Flight 93 the time to realize that this was a suicide mission and the chance to thwart it.” [MSNBC, 9/11/2006] CNN adds that it therefore “likely saved the White House or the US Capitol from destruction.” [CNN, 9/11/2006]

The September 11, 2001 attacks. From left to right: The World Trade Center, Pentagon, and Flight 93 crash. [Source: unknown] (click image to enlarge)The 9/11 attack: Four planes are hijacked, two crash into the WTC, one into the Pentagon, and one crashes into the Pennsylvania countryside. Nearly 3,000 people are killed.

The last routine communication takes place between air traffic control and the pilots of Flight 11 at 8:13 and 29 seconds. Boston Center air traffic controller Pete Zalewski is handling the flight, and instructs it to turn 20 degrees to the right. Pilot John Ogonowski immediately acknowledges the instruction, but seconds later he fails to respond to a command to climb to 35,000 feet. Zalewski repeatedly tries to reach the pilot over the next ten minutes, even using the emergency frequency, but gets no response (see 8:14 a.m.-8:24 a.m. September 11, 2001). The 9/11 Commission concludes that Flight 11 is hijacked at 8:14, or shortly afterwards (see 8:14 a.m. September 11, 2001). [New York Times, 10/16/2001; MSNBC, 9/11/2002; 9/11 Commission, 6/17/2004; 9/11 Commission, 7/24/2004, pp. 4]

In the event of a hijacking, all airline pilots are trained to key an emergency four-digit code into their plane’s transponder. This would surreptitiously alert air traffic controllers, causing the letters “HJCK” to appear on their screens. [CNN, 9/13/2001; Newsday, 9/13/2001; News (Portugal), 8/3/2002; 9/11 Commission, 7/24/2004, pp. 17-18] The action, which pilots should take the moment a hijack situation is known, only takes seconds to perform. [Christian Science Monitor, 9/12/2001; CNN, 9/12/2001] Yet during the hijackings of flights 11, 175, 77, and 93, none of the pilots do this. [CNN, 9/11/2001]

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

[Source: Mary Schwalm / North Andover Eagle-Tribune]The air traffic control tower at Logan International Airport in Boston is called by the FAA’s Boston Center and told that communication with Flight 11 has been lost, but when the tower supervisor looks at the plane through his binoculars, he can see nothing outwardly wrong with it. [North Andover Eagle-Tribune, 9/6/2011; CNHI News Service, 9/9/2011] Flight 11 took off from Logan Airport at 7:59 a.m. (see (7:59 a.m.) September 11, 2001). It was in communication with the Logan control tower before being passed on to the FAA’s Boston Center. All communications between the Logan tower and Flight 11 were routine, and tower operators received no indication that anything was wrong with the flight. [Boston Globe, 9/12/2001; Federal Aviation Administration, 9/17/2001 ; New York Times, 10/16/2001] But since the Boston Center instructed it to ascend to 35,000 feet, just before 8:14 a.m. (see 8:13 a.m. September 11, 2001), Flight 11 has failed to respond to all air traffic controller communications (see 8:14 a.m.-8:24 a.m. September 11, 2001). [Federal Aviation Administration, 9/17/2001 ; New York Times, 10/16/2001; 9/11 Commission, 8/26/2004, pp. 7 ]
Tower Supervisor Sees Nothing Wrong with Flight 11 - The Boston Center now calls the Logan tower to alert it to the problem. “We got a call in the tower that communication with the plane had been lost,” Mike Hilliard, the tower supervisor, will later recall. Then, Hilliard will say, the radar room, which is on a level below the tower room, “called and asked if we could still see the plane.” Hilliard looks at the radar screen and can see Flight 11’s track. He then grabs his binoculars, looks out the window through them, and can see Flight 11, because the sun is reflecting off its aluminum fuselage. The aircraft is flying “at 15,000 feet, and he wasn’t trailing vapor or smoke,” Hilliard will recall. Hilliard therefore informs the radar room that he cannot see anything wrong with the plane.
Assistant Says, 'I Hope It's Not a Hijack' - One of Hilliard’s assistants then says to the supervisor, “I hope it’s not a hijack.” This gives Hilliard an uneasy feeling. He replies, “It better not be, because if they got the airplane that quick, it’s a team that took the airplane.” He says to his assistant that the problem with Flight 11 has “got to be mechanical,” and then adds, “Nobody can get a plane that quick.” [North Andover Eagle-Tribune, 9/6/2011; CNHI News Service, 9/9/2011] The 9/11 Commission will conclude that Flight 11 is hijacked at around 8:14 a.m. (see 8:14 a.m. September 11, 2001). Flight 175, the second plane to crash into the World Trade Center, takes off from Logan Airport at 8:14 a.m. (see 8:14 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 4, 7]

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 ]

The 9/11 Commission will later conclude that Flight 11 is hijacked at 8:14 or shortly after. It will state, “Information supplied by eyewitness accounts indicates that the hijackers initiated and sustained their command of the aircraft using knives (as reported by two flight attendants); violence, including stabbing and slashing (as reported by two flight attendants); the threat of violence (as indicated by a hijacker in radio transmissions received by air traffic control); Mace (reported by one flight attendant); the threat of a bomb, either fake or real (reported by one flight attendant); and deception about their intentions (as indicated by a hijacker in a radio transmission received by air traffic control).” [9/11 Commission, 8/26/2004, pp. 8 ] The Commission says, “We do not know exactly how the hijackers gained access to the cockpit; FAA rules required that the doors remain closed and locked during flight.… Perhaps the terrorists stabbed the flight attendants to get a cockpit key, to force one of them to open the cockpit door, or to lure the captain or first officer out of the cockpit. Or the flight attendants may just have been in their way.” [9/11 Commission, 7/24/2004, pp. 5] Pilots are trained to handle hijackings by staying calm, complying with any requests, and, if possible, dialing an emergency four-digit code on their plane’s transponder. It only takes a few seconds to dial this code. [CNN, 9/12/2001] Yet, as the Boston Globe notes, “It appears that the hijackers’ entry was surprising enough that the pilots did not have a chance to broadcast a traditional distress call” (see (8:13 a.m.-9:28 a.m.) September 11, 2001). [Boston Globe, 11/23/2001] The Los Angeles Times reports that, when flight attendant Amy Sweeney makes a phone call from the plane, she says the hijackers have “just gained access to the cockpit.” [Los Angeles Times, 9/20/2001] Yet her first attempted call is not until 8:22, and, according to official accounts, her first call that stays connected is at 8:25, well past when the 9/11 Commission says the hijacker takeover occurs. [9/11 Commission, 8/26/2004, pp. 9-10 ; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] According to an employee at the FAA’s Boston Center, Flight 11 is hijacked while it is over Gardner, Massachusetts, about 45 miles northwest of Boston. [Telegraph (Nashua), 9/12/2001; Associated Press, 9/13/2001]

Flight 175 takes off from Boston’s Logan Airport, 16 minutes after its scheduled 7:58 departure time. [Washington Post, 9/12/2001; CNN, 9/17/2001; Guardian, 10/17/2001; Associated Press, 8/21/2002; Newsday, 9/10/2002]

John Ogonowski. [Source: Associated Press]At some unknown point after the hijacking begins, Flight 11’s talkback button is activated, which enables Boston flight controllers to hear what is being said in the cockpit. It is unclear whether John Ogonowski, the pilot, activates the talkback button, or whether a hijacker accidentally does so when he takes over the cockpit. A controller later says, “The button [is] being pushed intermittently most of the way to New York.” An article later notes that “his ability to do so also indicates that he [is] in the driver’s seat much of the way” to the WTC. Such transmissions continue until about 8:38 a.m. [Christian Science Monitor, 9/13/2001; MSNBC, 9/15/2001] However, Ogonowski fails to punch a four-digit emergency code into the plane’s transponder, which pilots are taught to do the moment a hijack situation is known (see (8:13 a.m.-9:28 a.m.) September 11, 2001).

Booker Elementary School in nearby Sarasota. With them are Secretary of Education Rod Paige, Bush’s senior adviser Karl Rove, and White House Chief of Staff Andrew Card. Kress goes over some key points for the talk Bush is due to give to the press after reading with the students at the school. However, Kress will later recall that the “president is a very punctual person,” and “I’ve never known him to be late.” Yet, “we finished the briefing on that fateful day, and we continued to talk for another ten minutes about people and politics in Texas. The time to leave came and passed.” Kress adds, “That struck me as unusual.” [Kessler, 2004, pp. 136-137; Dallas Morning News, 9/10/2006] According to the official schedule, the president is supposed to leave the resort at 8:30 a.m. for the drive to the school. [St. Petersburg Times, 7/4/2004] Yet, according to one account, he will not leave until as late as 8:39 (see (8:35 a.m.) September 11, 2001). [Washington Times, 10/7/2002]

Sara Low. [Source: Family photo / Associated Press]According to a computer presentation put forward as evidence in the 2006 trial of Zacarias Moussaoui, an unknown person—or persons—makes four calls from Flight 11. These are at 08:16:50, 08:20:11, 08:25:31, and 08:28:33. The calls do not appear to have gone through properly: they are each described as “On button pressed, no call made.” Though the trial exhibit identifies the caller(s) only as “Unknown Caller,” other evidence suggests that at least one of the calls is made by—or on behalf of—Sara Low, who is one of the plane’s flight attendants. Her father, Mike Low, later says he learned from FBI records that his daughter had given her childhood home phone number in Arkansas to another of the flight attendants, Amy Sweeney, for her to report the hijacking. Low speculates that the reason his daughter gave this particular number was that she had just moved home, and so, in the stress of the hijacking, her childhood phone number was the only one she could remember. The Moussaoui trial presentation lists Sweeney as making five calls from the plane. However, it says these are all to the American Airlines office at Boston’s Logan Airport. [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006; New York Times, 9/4/2007] Sara Low lets Sweeney use her father’s calling card in order to make these five calls from an Airfone (see 8:22 a.m.-8:24 a.m. September 11, 2001). [New York Observer, 6/20/2004]

Betty Ong. [Source: The Eagle-Tribune]Betty Ong, a flight attendant on Flight 11, begins relaying information about the trouble on her plane to employees at the American Airlines Southeastern Reservations Office in Cary, North Carolina. [9/11 Commission, 7/24/2004, pp. 5] Ong has just called the reservations office to report the hijacking of Flight 11, and is on the line with two employees there: Vanessa Minter and Winston Sadler (see 8:18 a.m. September 11, 2001). [Federal Bureau of Investigation, 9/12/2001, pp. 38-41; 9/11 Commission, 7/24/2004, pp. 453]
Ong Describes Hijacking but Gives Wrong Flight Number - Ong tells Minter and Sadler: “The cockpit’s not answering, somebody’s stabbed in business class, and I think there’s Mace, that we can’t breathe.… I think we’re getting hijacked.” Sadler asks Ong what flight she is on and Ong replies, incorrectly, “Flight 12.” She says her plane just left Boston and is supposed to go to Los Angeles, and the pilots are not answering the phone in the cockpit. She says she is in the jump seat, 3R, which is at the back of the plane, behind the coach section. [American Airlines, 9/11/2001, pp. 3-6; 9/11 Commission, 8/26/2004, pp. 6, 8 ] However, Amy Sweeney, another flight attendant who makes a call from Flight 11, is in the next-to-last row of passenger seats in the coach section of the plane, and she will say that Ong is sitting next to her (see (8:32 a.m.-8:44 a.m.) September 11, 2001). [New York Observer, 2/15/2004; New York Observer, 6/20/2004; 9/11 Commission, 8/26/2004, pp. 11 ]
Ong Says Two Flight Attendants Stabbed - Sadler asks Ong her name and she replies: “My name is Betty Ong. I’m number three [flight attendant] on Flight 11.” She says the number one flight attendant and the number five flight attendant have been stabbed. [American Airlines, 9/11/2001, pp. 3-6] These two attendants are Barbara Arestegui and Karen Martin. [9/11 Commission, 8/26/2004, pp. 6 ] Ong says, “Nobody knows who stabbed who and we can’t even get up to business class right now, ‘cause nobody can breathe.” She also says: “We can’t get into the cockpit. The door won’t open.” [American Airlines, 9/11/2001, pp. 3-6] Sadler takes notes of the call, using his computer “scratch pad.” [Federal Bureau of Investigation, 9/12/2001, pp. 42-44] He notifies Ong of this, saying, “I’m taking it down, all the information.” He tells Ong, “We’re also, you know, of course, recording this.” [American Airlines, 9/11/2001, pp. 3-6]
Ong Receiving Details of Hijacking from Colleague - During the entire conversation, Sadler will later recall, Ong seems to be talking to someone in the background and receiving information from them. [Federal Bureau of Investigation, 9/12/2001, pp. 42-44] This person is presumably Sara Low, another of the flight attendants, who was assigned to the front of the plane and so would have witnessed the hijacking when it happened. [Associated Press, 3/5/2009; New York Daily News, 3/6/2009; Arkansas Democrat-Gazette, 9/11/2011] Ong will keep repeating herself during the call, Minter will recall, such as repeatedly mentioning the stabbings on her plane. [Federal Bureau of Investigation, 9/12/2001, pp. 38-41] Nydia Gonzalez, a supervisor at the reservations office, has been alerted to the call and will soon join it (see 8:21 a.m. September 11, 2001).

Daniel Lewin. [Source: Akamai Technologies]An FAA memo written on the evening of 9/11, and later leaked, will suggest that a man on Flight 11 is shot and killed by a gun before the plane crashes into the World Trade Center. The “Executive Summary,” based on information relayed by a flight attendant to the American Airlines Operation Center, states “that a passenger located in seat 10B [Satam Al Suqami] shot and killed a passenger in seat 9B [Daniel Lewin] at 9:20 a.m.” (Note that since Flight 11 crashes at 8:46, the time must be a typographical error, probably meaning 8:20). A report in Israeli newspaper Ha’aretz on September 17 will identify Lewin as a former member of the Israel Defense Force Sayeret Matkal, Israel’s most successful Special Operations unit. [United Press International, 3/6/2002] Sayeret Matkal is a deep penetration unit that has been involved in assassinations, the theft of foreign signals intelligence materials, and the theft and destruction of foreign nuclear weaponry. It is best known for the 1976 rescue of 106 passengers at Entebbe Airport in Uganda. [New Yorker, 10/29/2001] Lewin founded Akamai, a successful computer company, and his connections to Sayeret Matkal will remain hidden until the gun story becomes known. [Guardian, 9/15/2001] FAA and American Airline officials will later deny the gun story and suggest that Lewin is probably stabbed to death instead. [Washington Post, 3/2/2002; United Press International, 3/6/2002] Officials assert that the leaked document was a “first draft,” and subsequently corrected, but decline to release the final draft, calling it “protected information.” However, an FAA official present when the memo is drafted will dispute the FAA’s claim, asserting that “[t]he document was reviewed for accuracy by a number of people in the room, including myself and a couple of managers of the operations center.” [WorldNetDaily, 3/7/2002] This unnamed official is probably Bogdan Dzakovic, a leader of the FAA’s “red team” conducting covert security inspections. He will later tell the 9/11 Commission: “There are serious indications that the FAA deceived the public about what happened on 9/11. On the afternoon of September 11, 2001, I was working in one of the FAA operations centers collecting information on details of what happened during the hijacking. We received information that a firearm was used on one of the hijacked aircraft.… That evening the administrator of FAA requested an executive summary covering the day’s activities, and this information about a gun was included in the summary. Days later, without any explanation or questioning of the summary’s author, the administrator publicly announced that no guns had been used in the hijacking. Several months passed when the press re-surfaced this issue. FAA’s initial response was that no so such executive summary existed. Later, when confronted with the document, FAA admitted the executive summary existed, but denied its accuracy. Sometime later I learned that another operations center also received a report that a firearm was used.… There were also reports of a possible explosive threatened on a flight.” [CBS News, 2/25/2002; 9/11 Commission, 5/22/2003; Village Voice, 2/8/2005]

Peggy Houck, a flight dispatcher at the American Airlines System Operations Control (SOC) center in Fort Worth, Texas, is contacted by an American Airlines flight and told that air traffic control has asked the aircraft to try to contact Flight 11. Houck is working at the desk for American Airlines’ transcontinental flights and is therefore the dispatcher responsible for Flight 11. [Federal Bureau of Investigation, 9/11/2001, pp. 5-7; 9/11 Commission, 1/8/2004 ; 9/11 Commission, 8/26/2004, pp. 9 ] Under FAA rules, dispatchers licensed by the agency are responsible for following aircraft in flight. Once a plane is in the air, a dispatcher must monitor its progress, relay safety information to the captain, and handle any problems. American Airlines assigns a dispatcher to each of its flights. [Dallas Morning News, 6/13/2002; Sydney Morning Herald, 6/14/2002; 9/11 Commission, 8/26/2004, pp. 86 ] Houck will later tell the FBI that the flight that calls her has sent a message to Flight 11 stating something along the lines of, “Good morning, ATC [air traffic control] wants you on [a certain radio frequency] and requests an acknowledgment,” but received no reply. Houck has, until now, had no direct contact with Flight 11 and the communication she receives from this other aircraft is the first indication she has of any problem on Flight 11. [Federal Bureau of Investigation, 9/11/2001, pp. 5-7; 9/11 Commission, 8/26/2004, pp. 9 ] Details of the aircraft that calls Houck are unclear. Houck will tell the 9/11 Commission, in 2004, that it is a “Seattle-Boston” flight. [9/11 Commission, 1/8/2004 ] However, interviewed by the FBI later today, she will refer to it as “another Boston flight,” suggesting that—like Flight 11—it had taken off from Logan International Airport in Boston. [Federal Bureau of Investigation, 9/11/2001, pp. 5-7] Houck, or another dispatcher at the SOC, will subsequently send an ACARS text message to Flight 11, but receive no response to it (see 8:23 a.m.-8:25 a.m. September 11, 2001).

[Grant, 2004, pp. 19] Marr tells Arnold that the personnel on the NEADS operations floor are ready to begin the exercise. Marr will tell the 9/11 Commission that his “primary communication” on this day “is to higher headquarters,” presumably meaning Arnold. However, the two men are not on a continual open line. [9/11 Commission, 1/23/2004 ] Arnold will tell the Commission that he and Marr “did not stay on the line continually, but spoke when information needed to be passed,” throughout the day.

Nydia Gonzalez. [Source: 9/11 Commission]Nydia Gonzalez, a supervisor at the American Airlines Southeastern Reservations Office in Cary, North Carolina, joins a phone call between two employees at her office and Betty Ong, a flight attendant on the hijacked Flight 11. [9/11 Commission, 8/26/2004, pp. 8-9 ] Ong called the reservations office at 8:18 a.m. to report the hijacking (see 8:18 a.m. September 11, 2001), and has since then been talking to two employees there: Vanessa Minter and Winston Sadler. Sadler pushed the emergency button on his phone to alert personnel in the operations area of the reservations office, so that one of them could pick up the call from Ong. A colleague of Gonzalez’s initially picked up the call, but Gonzalez quickly takes over from them. [Federal Bureau of Investigation, 9/12/2001, pp. 38-41; 9/11 Commission, 7/24/2004, pp. 453; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] Gonzalez, Minter, and Sadler are in different areas of the reservations office, but all three of them are able to monitor Ong’s call. [9/11 Commission, 11/19/2003 ]
Supervisor Told of Stabbings on Flight 11 - The first thing Gonzalez says when she joins the call is: “This is operations. What flight number are we talking about?” Ong earlier told Minter and Sadler, incorrectly, that she was on “Flight 12,” not Flight 11 (see 8:19 a.m. September 11, 2001). Sadler therefore tells Gonzalez, “Flight 12.” Ong quickly corrects him, saying: “We’re on Flight 11 right now. This is Flight 11.… Boston to Los Angeles.” She also repeats information she previously gave to Minter and Sadler, saying, “Our number one [flight attendant] has been stabbed and our [number] five [flight attendant] has been stabbed.” [American Airlines, 9/11/2001, pp. 3-6]
Supervisor Notifies Airline's Operations Center - Gonzalez is an operations specialist, and her responsibilities include monitoring any emergency situations with American Airlines flights and forwarding information to the American Airlines System Operations Control (SOC) center in Fort Worth, Texas. [9/11 Commission, 1/27/2004 ; Spencer, 2008, pp. 17] She immediately realizes the seriousness of the situation on Flight 11 and therefore, while remaining connected to Ong’s call, phones the SOC on a separate line to notify it of the problem (see (8:21 a.m.) September 11, 2001). [9/11 Commission, 11/19/2003 ; 9/11 Commission, 8/26/2004, pp. 9 ] Gonzalez will later recall that she finds Ong to be “calm, professional, and in control throughout the call.” [9/11 Commission, 1/27/2004 ] She will also say that during the time she is monitoring Ong’s call, she does not hear much commotion in the background. [Federal Bureau of Investigation, 9/12/2001, pp. 69-71]

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.

Madeline ‘Amy’ Sweeney. [Source: Nashua Telegraph / Getty Images]Madeline “Amy” Sweeney, a flight attendant on Flight 11, makes two unsuccessful attempts at calling the American Airlines flight services office at Logan International Airport in Boston. [9/11 Commission, 8/26/2004, pp. 9-10 ; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] Flight 11 took off from Logan Airport at 7:59 a.m. (see (7:59 a.m.) September 11, 2001). [New York Times, 9/13/2001] The American Airlines flight services office at the airport manages the scheduling and operation of flight attendants. Attendants go there to check in for duty and fill in their pre-flight paperwork, among other things. The office’s phone number is well known to the American Airlines flight attendants who operate out of Logan Airport. [9/11 Commission, 1/25/2004 ; 9/11 Commission, 8/26/2004, pp. 9 ] Sweeney first tries phoning the flight services office at 8:22 a.m., but the call fails to connect. Her second attempted call, two minutes later, also fails to connect. [9/11 Commission, 8/26/2004, pp. 9-10 ; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] Sweeney tries making the calls from a passenger seat in the next-to-last row of the coach section of the plane. She makes the attempted calls on an Airfone, using a calling card given to her by Sara Low, another of the plane’s flight attendants. [New York Observer, 2/15/2004; New York Observer, 6/20/2004; Arkansas Democrat-Gazette, 9/11/2011] Sweeney will finally reach the American Airlines flight services office on her third attempt to do so, at 8:25 a.m., and alert its staff to what is happening on her plane (see 8:25 a.m. September 11, 2001). [Federal Bureau of Investigation, 9/11/2001, pp. 57-58; 9/11 Commission, 8/26/2004, pp. 10 ]

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 ] 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 ] (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). [9/11 Commission, 7/24/2004, pp. 18-19] )

The American Airlines System Operations Control center in Fort Worth, Texas. [Source: American Airlines]Employees at the American Airlines System Operations Control (SOC) center in Fort Worth, Texas, send ACARS text messages to the pilots of the hijacked Flight 11, but receive no response. At 8:23 a.m., a flight dispatcher at the SOC sends an ACARS message to Flight 11. ACARS, meaning Aircraft Communications and Reporting System, is an e-mail system enabling company personnel on the ground to rapidly communicate with those in the cockpit of an in-flight aircraft. The message says: “Good morning.… ATC [air traffic control] looking for you on [radio frequency] 135.32.” No response is received from Flight 11. [9/11 Commission, 8/26/2004, pp. 9-10 ] It is unclear which dispatcher sends this ACARS message. Peggy Houck, the dispatcher responsible for Flight 11, will tell the 9/11 Commission, in 2004, that she tries to reach the flight “via the ACARS system” shortly after 8:20 a.m. [9/11 Commission, 1/8/2004 ] However, when she is interviewed by the FBI later today, Houck will say that “another” American Airlines dispatcher, besides herself, “sent an ACARS message to Flight 11… based upon ATC’s attempts to contact Flight 11.” [Federal Bureau of Investigation, 9/11/2001, pp. 5-7] At 8:25 a.m., Bob Marino, an American Airlines air traffic control specialist at the SOC, sends another ACARS message to Flight 11. This says: “Plz contact Boston Center ASAP.… They have lost radio contact and your transponder signal.” Again, no response is received from the plane. Subsequent ACARS messages sent to Flight 11 will also receive no reply. [9/11 Commission, 3/25/2004, pp. 14; 9/11 Commission, 8/26/2004, pp. 10 ]

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 ] 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, 8/13/2002] Boston Center will receive a third transmission from Flight 11 about ten minutes later (see (8:34 a.m.) September 11, 2001).

Colin Scoggins. [Source: John P. Meyer]Colin Scoggins, the military liaison at the FAA’s Boston Center, arrives at work an hour late and is informed of the hijacking of Flight 11. [Federal Aviation Administration, 9/20/2001; WAMU, 8/3/2006; Spencer, 2008, pp. 32-33] Scoggins is an experienced air traffic controller and specializes in airspace, procedures, and military operations. He is responsible for managing operating agreements between the Boston Center and other air traffic control facilities, and between Boston Center and the military. He is also responsible for generating the military schedules that keep FAA facilities synchronized with military airspace requirements, and has therefore developed personal relationships with most of the military units in his region. [Spencer, 2008, pp. 32-33]
Arrives One Hour Late - In a 2006 radio interview, Scoggins will recall that he arrives at work one hour late, saying, “That morning I actually came in, took an hour early on the front of my shift, so I didn’t get in until 8:30.” [WAMU, 8/3/2006] But in a statement that will be provided to the 9/11 Commission, he says he arrives at the Boston Center slightly earlier, at “about 8:25 a.m.” [Federal Aviation Administration, 9/20/2001] When he enters the building, a colleague tells him about the hijacking of Flight 11. [Spencer, 2008, pp. 33]
Heads to Credit Union - Rather than going immediately to help deal with the hijacking, Scoggins heads to the credit union at the center. He will recall, “I wasn’t in a rush because when hijacks do occur, sometimes too many people try to get involved, but instead they just get in the way.”
Mentions that Hijacked Plane Could Hit a Building - When he gets to the credit union, Scoggins decides he should go to the center’s traffic management unit, to make sure that fighter jets are launched in response to the hijacking. As he will later recall, he says to an employee at the credit union that “if it really came to it,” and fighter jets “had to stop the hijack from hitting a building or something, there wasn’t much [the fighters] could do.” [Federal Aviation Administration, 9/20/2001]
Updated on Hijacking - Scoggins then heads to the center’s operational floor, arriving there at about 8:35. [WAMU, 8/3/2006; Griffin, 2007, pp. 335] He goes to the traffic management unit and the desk of Daniel Bueno, who is the unit’s supervisor. Bueno brings Scoggins up to date on the details of the hijacking. He tells him: “It sounds real. We heard a Mideastern or Arabic voice on radio. They’ve also turned off the transponder to prevent the hijack code from appearing.” Bueno says the Boston Center controllers are still tracking the primary radar return for Flight 11, but they lack information on its altitude. According to author Lynn Spencer, it occurs to Scoggins that NORAD’s Northeast Air Defense Sector (NEADS) might be able to provide altitude information for Flight 11, “because the FAA radar system filters out certain altitude information that NEADS gets.” He will therefore phone NEADS as soon as he arrives at his station (see (8:35 a.m.) September 11, 2001). [Spencer, 2008, pp. 33]

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 ] , 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).

Boston flight control begins notifying the chain of command that a suspected hijacking of Flight 11 is in progress. Those notified include the center’s own facility manager, the FAA’s New England Regional Operations Center (ROC) in Burlington, Massachusetts, and the FAA Command Center in Herndon, Virginia (see 8:28 a.m. September 11, 2001). [Federal Aviation Administration, 9/17/2001 ; 9/11 Commission, 8/26/2004, pp. 11 ] According to the 9/11 Commission, this is consistent with FAA protocol: “From interviews of controllers at various FAA centers, we learned that an air traffic controller’s first response to an aircraft incident is to notify a supervisor, who then notifies the traffic management unit and the operations manager in charge. The FAA center next notifies the appropriate regional operations center (ROC), which in turn contacts FAA headquarters.” [9/11 Commission, 7/24/2004, pp. 458] But according to Ben Sliney, the national operations manager at the FAA’s Command Center, “the protocol was in place that the center that reported the hijacking would notify the military.… I go back to 1964, where I began my air traffic career, and they have always followed the same protocol.” [9/11 Commission, 6/17/2004] Yet Boston Center supposedly will not contact NORAD about Flight 11 until about 12 minutes later (see (8:37 a.m.) September 11, 2001). Already about ten minutes have passed since controllers first noticed a loss of contact with Flight 11 (see (8:15 a.m.) September 11, 2001). Boston reportedly also contacts several other air traffic control centers about the suspected hijacking at this time (see 8:25 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 ] 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).

Sean O’Keefe. [Source: Bill Ingalls / NASA]Sean O’Keefe, the deputy director of the Office of Management and Budget, stops by Vice President Dick Cheney’s White House office for an unscheduled visit. According to journalist and author Stephen Hayes, Cheney’s colleagues have learned to keep any impromptu sessions with him short and succinct. Yet O’Keefe spends more than 20 minutes with the vice president. Cheney is scheduled to meet John McConnell, his chief speechwriter, at 8:30 a.m. Yet McConnell is left waiting outside the office while the vice president is deep in discussion with O’Keefe. According to Hayes, while the topic of O’Keefe and Cheney’s conversation seems urgent at present, “In time, neither man would be able to recall what it was that had been so important.” [Hayes, 2007, pp. 328-330] O’Keefe is a former Pentagon comptroller, and had been a close confidant of Dick Cheney’s when he was the secretary of defense, in the early 1990s. He was also secretary of the navy from 1992 to 1993. [New York Times, 7/7/1992; New York Times, 2/3/2003]

Amy Sweeney, a flight attendant on Flight 11, finally reaches the American Airlines flight services office at Logan International Airport in Boston, and tells the employee who answers the call about the trouble on her plane. Sweeney’s two previous attempts at calling the flight services office failed to connect (see 8:22 a.m.-8:24 a.m. September 11, 2001). But her third attempted call is answered by Evelyn Nunez, a passenger service agent for American Airlines. [Federal Bureau of Investigation, 9/11/2001, pp. 57-58; 9/11 Commission, 2004, pp. 4; 9/11 Commission, 8/26/2004, pp. 9-10 ]
Sweeney Says Two Attendants Stabbed, One Passenger Had Throat Cut - Sweeney talks fast during the call. She says she is an American Airlines flight attendant, but does not give her name. Nunez will later tell the FBI that Sweeney says that “Flight 12 at Gate 32 had two flight attendants stabbed.” [Federal Bureau of Investigation, 9/11/2001, pp. 57-58] (Although Sweeney is on Flight 11, not Flight 12, Flight 11 departed from Gate 32 at Logan Airport (see 7:40 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 7 ] ) Sweeney says a passenger seated in row 9 of the plane had their throat cut by a passenger in seat 10B. [Federal Bureau of Investigation, 9/11/2001, pp. 57-58] This would be a reference to passenger Daniel Lewin being attacked by hijacker Satam Al Suqami (see (8:20 a.m.) September 11, 2001). [Ha'aretz, 7/22/2004; 9/11 Commission, 7/24/2004, pp. 5] Sweeney also says there is a bomb on the plane. [Federal Bureau of Investigation, 9/11/2001, pp. 57-58]
Sweeney Given Details of Hijacking by Another Flight Attendant - Sweeney makes this call from the next-to-last row of passenger seats in the coach section of her plane, using an Airfone. [New York Observer, 2/15/2004; New York Observer, 6/20/2004] She gets her information about the trouble on Flight 11 from Sara Low, another of the flight attendants, who was assigned to the front of the plane and so would have witnessed the hijacking when it happened. [Boston Herald, 12/15/2008; Associated Press, 3/5/2009] But after 1 minute and 47 seconds, the call is cut off. [9/11 Commission, 7/24/2004, pp. 6; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006]
Flight Services Manager Overhears Call - Michael Woodward, an American Airlines flight services manager at Logan Airport, hears Nunez talking on the phone to Sweeney. Nunez is talking in a “rather loud” voice, Woodward will recall, and keeps saying to Sweeney: “What, what, what?… Who’s hurt?… What?” When Woodward asks what is wrong, Nunez says she has received an odd phone call, in which the caller said someone was hurt on Flight 12. “She indicated that someone had been hurt, stabbed,” Woodward will recall. Woodward will tell the 9/11 Commission that he mistakenly thinks the incident the caller described “was air rage, because there was a lot of that type of thing going on at the time.” He thinks that “maybe there was a disturbance in the terminal.” Woodward will subsequently head to a departure gate to see if anything is wrong there (see (8:27 a.m.) September 11, 2001). [9/11 Commission, 1/25/2004 ]
Agent Determines Name of Hijacker - Nunez immediately calls flight operations for American Airlines to determine the status of Flight 12, the plane Sweeney said she was on. Nunez learns that it was in fact Flight 11 that recently left Logan Airport. She then runs a computer check to find the name of the passenger Sweeney identified, who was in seat 10B on Flight 11. Nunez determines that the passenger was Al Suqami. [Federal Bureau of Investigation, 9/11/2001, pp. 57-58] Sweeney will call the American Airlines flight services office again at 8:29 a.m. and 8:32 a.m. (see 8:29 a.m. September 11, 2001 and (8:32 a.m.-8:44 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 6; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006]

At 8:26, Flight 11, which is already way off course, makes an unplanned 100-degree turn to the south over Albany, New York. A minute later, it turns right, to the south-southwest. Then, two minutes on, at 8:29, it turns left to the south-southeast. Boston air traffic controllers never lose sight of the flight, though they can no longer determine altitude as the transponder is turned off. Its last known altitude was 29,000 feet. [Christian Science Monitor, 9/13/2001; Federal Aviation Administration, 9/17/2001 ; National Transportation Safety Board, 2/19/2002 ; MSNBC, 9/11/2002] Before this turn, the FAA had tagged Flight 11’s radar dot for easy visibility and, at American Airlines’ System Operations Control (SOC) in Fort Worth, Texas, “All eyes watched as the plane headed south. On the screen, the plane showed a squiggly line after its turn near Albany, then it straightened.” [Wall Street Journal, 10/15/2001] Boston air traffic controller Mark Hodgkins later says, “I watched the target of American 11 the whole way down.” [ABC News, 9/6/2002] However, apparently, NORAD’s Northeast Air Defense Sector (NEADS) has different radar. When they are finally told about the flight, they cannot find it (see Shortly After 8:37 a.m. September 11, 2001). NEADS has to repeatedly phone the FAA, airlines, and others, for clues as to the plane’s location. NEADS will eventually focus on a radar blip they believe might be Flight 11, and watch it close in on New York. [Newhouse News Service, 1/25/2002; Aviation Week and Space Technology, 6/3/2002; ABC News, 9/11/2002]

A Sikorsky S-76A helicopter flying over New York. [Source: Sikorsky]A helicopter is tracked on radar apparently crashing into the World Trade Center, according to a report later given by a New York air traffic controller over an FAA teleconference.
Helicopter Is 'the Only Target that We Saw ... to Fly into the Trade Center' - At around 10:15 a.m., Tom White, an operations manager at the FAA’s New York Terminal Radar Approach Control (TRACON), will tell those on the FAA teleconference that his facility tracked a Sikorsky helicopter that had taken off from the airport in Poughkeepsie, New York, and this helicopter appeared to fly into the WTC at 8:27 a.m. (see (10:15 a.m.) September 11, 2001). White will add that, after replaying radar information, it is concluded that the helicopter is “the only target that we saw in the vicinity of the Trade Center at 12:27 [Zulu time, or 8:27 a.m. Eastern time] to fly into the Trade Center.” [Federal Aviation Administration, 9/11/2001; 9/11 Commission, 5/21/2004] (However, the first crash at the WTC will not occur until 8:46 a.m. (see 8:46 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 7] ) The “Poughkeepsie airport” the helicopter took off from is presumably Dutchess County Airport. Sikorsky reportedly bases a fleet of its S-76 helicopters at Dutchess County Airport, “dispatching them to the New York metro areas as needed.” [Site Selection, 5/2000; Aviation International News, 8/1/2003] Poughkeepsie is about 70 miles north of New York City. [Pittsburgh Post-Gazette, 2/3/2008]
Helicopter 'Consistent with the Speed' of What Hits WTC - White will say the helicopter’s tail number is N7601S, that it departed the Poughkeepsie airport at 8:03 a.m., and that it then headed south at a speed of around 160 knots, or 184 miles per hour. He will add: “The tower [presumably the air traffic control tower at the Poughkeepsie airport] says the only thing they had southbound at that time was a Sikorsky helicopter, which is consistent with the speed that we followed it down.… They’re saying they replayed the radar and it’s consistent with the speed of what went into the [WTC] tower.” [Federal Aviation Administration, 9/11/2001] (However, an analysis by the US government will later estimate that Flight 11 hits the WTC at 494 miles per hour, or 429 knots, which is significantly faster than the helicopter was flying. [New York Times, 2/23/2002] )
Mistaken Information Later Corrected - It will apparently take until early afternoon for the suspicions about the Sikorsky helicopter hitting the WTC to be dismissed. An FAA chronology of this day’s events will state that at 1:00 p.m., the “Sikorsky helicopter” is “now believed not to have hit the WTC.” [Federal Aviation Administration, 1/2/2002 ] Another FAA chronology will state that at 1:04 p.m., it is reported that the Sikorsky helicopter “landed 20 minutes early, normal GE run at 12:28Z [i.e. 8:28 a.m. Eastern time] to WTC.” (It is unclear what is meant by “normal GE run.”) [Federal Aviation Administration, 9/11/2001]

Betty Ong, a flight attendant on Flight 11, tells American Airlines employees on the ground the seat numbers of two hijackers who have gained unauthorized access to the cockpit of her plane. [American Airlines, 9/11/2001, pp. 7-19; 9/11 Commission, 7/24/2004, pp. 6] Ong is on the phone with three members of staff at the American Airlines Southeastern Reservations Office in North Carolina, and has been describing to them the trouble on her plane. [Federal Bureau of Investigation, 9/12/2001, pp. 38-41; 9/11 Commission, 8/26/2004, pp. 8 ] She previously said she thought that two hijackers had forced their way into the cockpit, but could provide no description of them (see 8:22 a.m.-8:24 a.m. September 11, 2001). [American Airlines, 9/11/2001, pp. 3-6; American Airlines, 9/11/2001, pp. 7-19; Federal Bureau of Investigation, 9/12/2001, pp. 69-71]
Ong Provides Hijackers' Seat Numbers - Nydia Gonzalez, one of the reservations office employees, now asks Ong: “Do you know any information as far as the gents, the men that are in the cockpit with the pilots. Were they from first class?” Ong replies that the men were in seats 2A and 2B. [American Airlines, 9/11/2001, pp. 7-19] These seats, in the first class section of the plane, were occupied by hijackers Wail Alshehri and Waleed Alshehri. Ong would not have seen these two men, as she is at the back of the plane. [9/11 Commission, 11/19/2003 ; 9/11 Commission, 8/26/2004, pp. 6 ] However, the reservations office employees gain the impression that she is getting information from someone else, such as another flight attendant.

Gonzalez Relays Information to Airline Operations Center - Gonzalez has been passing on the information Ong provides to Craig Marquis, a manager at the American Airlines System Operations Control (SOC) center in Texas (see (8:21 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 9 ; Spencer, 2008, pp. 17-18] She has just told Marquis that, according to Ong, the “number five” flight attendant on Flight 11—Barbara Arestegui—has been stabbed, but “seems to be breathing,” and the “number one” flight attendant—Karen Martin—has been “stabbed pretty badly, and she’s lying down on the floor,” possibly unconscious. The other flight attendants are at the back of the plane with Ong, Gonzalez said. Gonzalez also told Marquis that the passengers in the coach section “might not be aware of what’s going on right now,” meaning they are unaware that their plane has been hijacked.
Ong Says Pilots Made No Announcements - Gonzalez now relays to Marquis the hijackers’ seat numbers that Ong provided, and adds that the two hijackers “are in the cockpit with the pilots.” She then returns to her conversation with Ong. She asks if the pilots have “made any announcements on the PA system.” [American Airlines, 9/11/2001, pp. 7-19] Ong says there have been no announcements. [Federal Bureau of Investigation, 9/12/2001, pp. 38-41; Federal Bureau of Investigation, 9/12/2001, pp. 69-71] Gonzalez then asks if Flight 11 is “still flying erratically” (see 8:25 a.m. September 11, 2001). Ong says that “right now it’s more or less stabilized.” [American Airlines, 9/11/2001, pp. 7-19] Later during her call with the reservations office, Ong will provide the seat number of a third hijacker on her plane (see 8:35 a.m.-8:36 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 12 ]

The FAA Command Center, the center of daily management of the US air traffic system. On 9/11 it is managed by Ben Sliney (not pictured here). [Source: CNN]The FAA’s Boston Center calls the FAA Command Center and says it believes Flight 11 has been hijacked and is heading toward the New York Center’s airspace. The Command Center immediately establishes a teleconference between the Boston, New York, and Cleveland air traffic control centers, so Boston can help the other centers understand what is happening, in case Flight 11 should enter their airspace. Minutes later, in line with the standard hijacking protocol, the Command Center will pass on word of the suspected hijacking to the FAA’s Washington headquarters (see 8:32 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 19; 9/11 Commission, 8/26/2004, pp. 11 ; Spencer, 2008, pp. 21]
National Operations Manager Learns of Hijacking - A supervisor at the Command Center promptly passes on the news of the possible hijacking to Ben Sliney, who is on his first day as the national operations manager there. The supervisor says the plane in question is “American Flight 11—a 767 out of Boston for Los Angeles.” According to author Lynn Spencer, “Sliney flashes back to the routine for dealing with hijackings from the days when they were more common.” The procedure is to “[k]eep other aircraft away from the errant plane. Give the pilots what they need. The plane will land somewhere, passengers will be traded for fuel, and difficult negotiations with authorities will begin. The incident should resolve itself peacefully, although the ones in the Middle East, he recalls, often had a more violent outcome.” Apparently not expecting anything worse to happen, Sliney continues to the conference room for the daily 8:30 staff meeting there (see 8:30 a.m.-8:40 a.m. September 11, 2001).
Command Center a 'Communications Powerhouse' - The FAA Command Center is located in Herndon, Virginia, 25 miles from Washington, DC. According to Spencer, it “is a communications powerhouse, modeled after NASA’s Mission Control. The operations floor is 50 feet wide and 120 feet long, packed with tiered rows of computer stations, and at the front, seven enormous display screens show flight trajectories and weather patterns.” The center has nearly 50 specialists working around the clock, planning and monitoring the flow of air traffic over the United States. These specialists work with airlines and air traffic control facilities to fix congestion problems and deal with weather systems. [Spencer, 2008, pp. 1 and 19-20]

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 ]
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 ; 9/11 Commission, 4/26/2004 ]
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 ]
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 ] 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 ] 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). [9/11 Commission, 8/26/2004, pp. 12 ]

Captain Charles Leidig. [Source: US Navy]Brigadier General Montague Winfield, the deputy director for operations (DDO) in the National Military Command Center (NMCC) at the Pentagon, leaves his post to attend a pre-scheduled meeting, allowing a colleague, who only recently qualified to take over his position, to stand in for him, and not returning to his post until after the terrorist attacks have ended. [9/11 Commission, 7/21/2003 ; 9/11 Commission, 4/29/2004 ; 9/11 Commission, 6/17/2004]
Winfield Attends Air Force-Convened Meeting - Winfield leaves his post to attend what a 9/11 Commission memorandum will call “an unrelated, closed-door personnel meeting convened by the Air Force to discuss the rating of Air Force officers.” [9/11 Commission, 7/21/2003 ] Another Commission memorandum will state that this meeting is a “session for general officers who rated Air Force officers.” It is unclear whether the meeting takes place somewhere in the NMCC or outside the center. The Commission memorandum will only say that it takes place “elsewhere in [Joint Chiefs of Staff] spaces.” At least one of the NMCC’s other qualified DDOs, Brigadier General Norman Seip, is also attending it.
Winfield Asked Colleague to Replace Him on Previous Day - Winfield is temporarily replaced as DDO by Captain Charles Leidig. Leidig only joined the operations directorate of the Joint Chiefs of Staff in July 2001, when he assumed duties as the deputy for Command Center operations. In that, his usual role, he is responsible for the maintenance, operation, and training of watch teams for the NMCC. He qualified to stand in as the DDO in the NMCC about a month ago, in August 2001. The previous afternoon, Winfield asked Leidig to relieve him for a portion of his duty this morning, and Leidig agreed to do so.
Leidig Takes Over as DDO - As arranged, Leidig takes over from Winfield as DDO at 8:30 a.m., allowing Winfield to attend his meeting. Upon arrival at the NMCC, Leidig receives the intelligence and other turn over briefings. After seeing the reports of the plane crashes in New York on television, he will be responsible for convening a significant event conference (see 9:29 a.m.-9:34 a.m. September 11, 2001), which he soon upgrades to an air threat conference (see 9:37 a.m.-9:39 a.m. September 11, 2001). [9/11 Commission, 4/29/2004 ; 9/11 Commission, 6/17/2004 ]
Winfield Does Not Resume Duties until Attacks Are Over - Even though it becomes obvious that a coordinated attack is under way when television shows the second plane hitting the World Trade Center at 9:03 a.m. (see 9:03 a.m. September 11, 2001), Winfield apparently remains in his meeting instead of resuming his duties as DDO (see (Shortly After 9:03 a.m.) September 11, 2001). He will only take over from Leidig as DDO after Flight 93 crashes in Pennsylvania, apparently at around 10:30 a.m. (see (10:30 a.m.) September 11, 2001). [9/11 Commission, 4/29/2004 ; 9/11 Commission, 6/17/2004] In later interviews for television, Winfield will give the impression that he remained in charge of the NMCC throughout the 9/11 attacks, and make no mention of having allowed a stand-in to take his place during this most critical period of time. [CNN, 9/4/2002; ABC News, 9/11/2002]

Tape recorders that normally record all of the air traffic monitoring stations on the operations floor at NORAD’s Northeast Air Defense Sector (NEADS) fail to record the positions of the two NEADS employees who are responsible for controlling the fighter jets launched from Otis Air National Guard Base in response to the hijacked Flight 11 (see 8:46 a.m. September 11, 2001). [9/11 Commission, 10/28/2003 ; 9/11 Commission, 7/24/2004, pp. 459; Shenon, 2008, pp. 203-204]
No Recordings of Two Radio Channels - The 9/11 Commission Report will state that “there are no NEADS recordings available of the NEADS senior weapons director and weapons director technician position responsible for controlling the Otis [Air National Guard Base] scramble.” [9/11 Commission, 7/24/2004, pp. 459] According to an e-mail sent during the Commission’s investigation by Miles Kara, one of the Commission’s staff members, the two NEADS employees whose positions are not recorded are Steve Hedrick and Brad Gardner. Kara will write: “Since we have zero evidence of the voices of Hedrick and Gardner [on the recordings of the NEADS operations floor], the NORAD position that their channels were never recorded may be accurate.… We never hear them.” [9/11 Commission, 5/25/2004] The 9/11 Commission will state, however, that it “found a single communication from the weapons director or his technician on the guard frequency at approximately 9:11, cautioning the Otis fighters, ‘remain at current position [holding pattern] until FAA requests assistance’” (see 9:09 a.m.-9:13 a.m. September 11, 2001).
Positions Not Recorded Due to 'Technical Issue' - The 9/11 Commission will say there are no recordings of the two positions because of “a technical issue,” although it will give no details of what that issue might be. [9/11 Commission, 7/24/2004, pp. 459] There are four Dictaphone multi-channel reel-to-reel tape recorders in a corner of the NEADS operations floor, which should be recording every radio channel. [Vanity Fair, 8/1/2006] These tape recorders are run by General Dynamics. Richard Crane is the technical representative of General Dynamics at NEADS who is responsible for the recordings on this day. [9/11 Commission, 10/28/2003 ; 9/11 Commission, 10/28/2003 ]

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 ]
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 ] 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 ; 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 ; 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 ] 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 ; 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. [9/11 Commission, 1/27/2004]

Mike Canavan testifying before the 9/11 Commission. [Source: C-SPAN]Protocols in place on 9/11 state that if the FAA requests the military to go after an airplane, “the escort service will be requested by the FAA hijack coordinator by direct contact with the National Military Command Center (NMCC).” [Federal Aviation Administration, 11/3/1998] Acting FAA Deputy Administrator Monte Belger states essentially the same thing to the 9/11 Commission, “The official protocol on that day was for the FAA headquarters, primarily through the hijack coordinator… to request assistance from the NMCC if there was a need for [Defense Department] assistance.” [9/11 Commission, 6/17/2004] However, the hijack coordinator, FAA Office of Civil Aviation Security Director Mike Canavan, is in Puerto Rico and claims to have missed out on “everything that transpired that day.” The 9/11 Commission fails to ask him if he had delegated that task to anyone else while he was gone. [9/11 Commission, 5/23/2003; 9/11 Commission, 7/24/2004, pp. 17] Monte Belger will later say simply that “an FAA security person” runs the “hijack net” open communication system during 9/11. [9/11 Commission, 6/17/2004]

Kirk Lippold. [Source: CNN]At the CIA headquarters in Langley, Virginia, three senior CIA officers—John Russack, Don Kerr, and Charlie Allen—are having breakfast with Navy Commander Kirk Lippold. Lippold was the commanding officer of the USS Cole when it was attacked in Yemen the previous year (see October 12, 2000). The men’s discussion is focused on terrorism. Lippold is upset that the American public still does not recognize the threat it poses, and says that it will take a “seminal event” to awaken them to the problem. Following the breakfast, Lippold heads to the Counterterrorist Center at CIA headquarters for some briefings. Just minutes later, after the WTC is hit, Charlie Allen will contact Lippold and tell him, “The seminal event just happened.” [Tenet, 2007, pp. 162-163]

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

At the District of Columbia Fire and EMS Training Academy, firefighters are taking part in what is described as a “counterterrorism class” or “antiterrorism exercises.” This is in preparation for the annual meetings of the International Monetary Fund (IMF) and the World Bank, which are scheduled to take place in Washington, DC, at the end of this month. Numerous individuals who will later respond to the attack on the Pentagon are in attendance. These include some firefighters with the Metropolitan Washington Airports Authority (MWAA) at Reagan National Airport. [CBS News, 9/17/2001; Goldberg et al., 2007, pp. 69 and 78] Captain Scott McKay of the Arlington County Fire Department (ACFD) is also reportedly “attending a counterterrorism class with the FBI in the District [of Columbia].” [Washington Post, 9/20/2001] And other ACFD personnel are reportedly “engaged in meetings in the District of Columbia, preparing for the upcoming International Monetary Fund (IMF) conference.” [US Department of Health and Human Services, 7/2002, pp. A4] FBI Special Agent Christopher Combs, who is the regular FBI liaison to the fire services and routinely cross-trains with regional departments, is at the Fire Academy, “training firefighters in counterterrorism tactics.” Combs serves on the FBI’s National Capital Response Squad (NCRS), an antiterrorism rapid response unit. [Goldberg et al., 2007, pp. 76] Members of the NCRS will be notified and recalled after the second WTC crash, and Combs will subsequently head to the Pentagon after hearing of the attack there, arriving at 9:49 a.m. [US Department of Health and Human Services, 7/2002, pp. C45 and 1-1]

NASA’s KC-135 in parabolic flight. [Source: NASA]A special aircraft operated by NASA is in the air over western New York State at the time of the terrorist attacks and, at one point, a large aircraft, which those on board later learn is the hijacked Flight 93, flies less than 1,000 feet below it. [Space Center Roundup, 9/2002 ] The plane, NASA 931, is a modified KC-135—a four-engine military aircraft similar to the Boeing 707. [National Aeronautics and Space Administration, 10/2000, pp. 28; National Aeronautics and Space Administration, 10/29/2004] It is used by NASA for reduced gravity research, and is known as the “Weightless Wonder” or sometimes the “Vomit Comet.” The aircraft creates weightless conditions for brief periods by flying up and down in large parabolic arcs. [NASAexplores, 1/30/2003] It is regularly operated from NASA’s Glenn Research Center in Cleveland, Ohio, next to Cleveland Hopkins International Airport, and usually flies four days a week. [National Aeronautics and Space Administration, 10/2000, pp. 140; National Journal's Technology Daily, 11/27/2002; National Aeronautics and Space Administration, 10/29/2004] A typical flight lasts two to three hours and consists of the plane flying 40 to 60 parabolas. [NASAexplores, 1/30/2003]
Scientists from Houston Conducting Microgravity Experiments - A team of scientists from NASA’s Johnson Space Center in Houston, Texas, has flown to Cleveland to conduct microgravity experiments on the KC-135. [Cleveland Free Times, 9/6/2006] Dominic Del Rosso, the test director on the plane, will later recall that the team is flying over western New York State when the terrorist attacks occur. During the routine mission, the KC-135 cruises back and forth along the New York shore of Lake Ontario, climbing and descending to create a freefall condition to simulate microgravity. Del Rosso will comment, “To think that this type of maneuver might ever seem threatening never crossed my mind until [September 11].” The plane’s crew members are notified at some point that a large plane is intersecting their flight path less than 1,000 feet below them, instead of the usual 2,000-foot minimum distance. They will later learn that this aircraft is the hijacked Flight 93, which crashes in Pennsylvania (see (10:06 a.m.) September 11, 2001). Del Rosso will recall, “After the unwanted flyby, we landed having no idea why or what was going on.” [Space Center Roundup, 9/2002 ] The scientists are unable to return to Houston on this day, as scheduled, after the FAA orders all planes to land (see (9:45 a.m.) September 11, 2001), and so have to be put up in a hotel in Cleveland. [Cleveland Free Times, 9/6/2006]

Offutt Air Force Base control tower during Global Guardian 1998. [Source: Jeffery S. Viano]As the 9/11 attacks are taking place, a large military training exercise called Global Guardian is said to be “in full swing.” It has been going on since the previous week. [Omaha World-Herald, 2/27/2002; Omaha World-Herald, 9/10/2002] Global Guardian is an annual exercise sponsored by US Strategic Command (Stratcom) in cooperation with US Space Command and NORAD. One military author defines Stratcom as “the single US military command responsible for the day-to-day readiness of America’s nuclear forces.” [Arkin, 2005, pp. 59]
Exercise Tests Military's Ability to Fight a Nuclear War - Global Guardian is a global readiness exercise involving all Stratcom forces and aims to test Stratcom’s ability to fight a nuclear war. It is one of many “practice Armageddons” that the US military routinely stages. [Bulletin of the Atomic Scientists, 11/1/1997; Associated Press, 2/21/2002; Omaha World-Herald, 2/27/2002; Omaha World-Herald, 9/10/2002] It links with a number of other military exercises, including Crown Vigilance (an Air Combat Command exercise), Apollo Guardian (a US Space Command exercise), and the NORAD exercises Vigilant Guardian and Amalgam Warrior. [US Department of Defense, 5/1997; GlobalSecurity (.org), 4/27/2005] Global Guardian is both a command post and a field training exercise, and is based around a fictitious scenario designed to test the ability of Stratcom and its component forces to deter a military attack against the US. Hundreds of military personnel are involved. [US Congress, n.d.; Collins Center Update, 12/1999 ; Times-Picayune, 9/8/2002] The exercise involves “a lot of the elements of what ultimately would be the nuclear command and control system in support of a national emergency,” according to Admiral Richard Mies, the commander in chief of Stratcom. It includes an “exercise secretary of defense” and “an exercise president.” Mies will say that because of the exercise, “A lot of [Stratcom’s] command and control systems that, in peacetime, are normally not on alert were at a much, much higher state of alert [on September 11] and we had a number of aircraft, manned control aircraft that were airborne that were simulating their wartime roles.” [NET News, 12/27/2011]
Exercise Normally Held in October or November - According to a 1998 Internet article by the British American Security Information Council—an independent research organization—Global Guardian is held in October or November each year. [Kristensen, 10/1998] In his book Code Names, NBC News military analyst William Arkin dates this exercise for October 22-31, 2001. [Arkin, 2005, pp. 379] And a military newspaper reported in March 2001 that Global Guardian was scheduled for October 2001. [Space Observer, 3/23/2001, pp. 2 ] If this is correct, then some time after March, the exercise must have been rescheduled for early September.
Exercise Includes a 'Computer Network Attack' - Furthermore, a 1998 Defense Department newsletter reported that for several years Stratcom had been incorporating a computer network attack (CNA) into Global Guardian. The attack involved Stratcom “red team” members and other organizations acting as enemy agents, and included attempts to penetrate the command using the Internet and a “bad” insider who had access to a key command and control system. The attackers “war dialed” the phones to tie them up and sent faxes to numerous fax machines throughout the Command. They also claimed they were able to shut down Stratcom’s systems. Reportedly, Stratcom planned to increase the level of computer network attack in future Global Guardian exercises. [IAnewsletter, 6/1998 ] It is unclear if a computer network attack is incorporated into Global Guardian in 2001.

Fire truck parked outside the Pentagon. [Source: Jon Culberson]Preparations are underway at the Pentagon heliport, located about 150 feet from the west side of the building, for the expected arrival of President Bush at around midday. Bush had left from the Pentagon the previous day for his visit to Florida. He occasionally uses the Pentagon heliport rather than the White House grounds when going by helicopter to and from Air Force One at Andrews Air Force Base. [Goldberg et al., 2007, pp. 64] The White House grounds are unavailable because the annual Congressional picnic is scheduled to take place there this afternoon. The White House hosts this event for members of Congress and select staffers; around 1,200 guests are due to attend, until the attacks lead to it being canceled. [Scripps Howard News Service, 9/11/2001; Scheib and Friedman, 2007, pp. 254-255; Hayes, 2007, pp. 344] Three firefighters from the fire department at nearby Fort Myer had arrived at the Pentagon at around 7:30 a.m. to man the fire station next to the heliport. [Newsweek, 9/28/2001; JEMS, 4/2002, pp. 22 ; Goldberg et al., 2007, pp. 65] “Every day they have an aircraft flying, we’re there,” firefighter Alan Wallace will later explain. [Pentagram, 9/14/2001] Wallace decides to pull the fire truck out of the fire station and place it in a position more accessible to the heliport landing pad. [First Due News, 4/17/2003] The truck is equipped with the special chemical foam used in fighting jet fuel fires. [Goldberg et al., 2007, pp. 65] Wallace parks it about 15 feet from the Pentagon’s west wall, facing toward the landing pad. Wallace will recall that with many vehicles—belonging to the Secret Service and other agencies—expected to be around for the president’s arrival, he “wanted the crash truck out of the station and parked in a good location, for easy access to the heliport in case of an emergency.” [First Due News, 4/17/2003] When the Pentagon is hit at 9:37 a.m., the aircraft will crash into an area of the building next to the heliport (see 9:37 a.m. September 11, 2001). [USA Today, 9/12/2001; American Forces Press Service, 9/7/2006]

At Fort Belvoir, an army base 12 miles south of the Pentagon, Lt. Col. Mark R. Lindon is conducting a “garrison control exercise” when the 9/11 attacks begin. The object of this exercise is to “test the security at the base in case of a terrorist attack.” Lindon later says, “I was out checking on the exercise and heard about the World Trade Center on my car radio. As soon as it was established that this was no accident, we went to a complete security mode.” Staff Sgt. Mark Williams of the Military District of Washington Engineer Company at Fort Belvoir also later says: “Ironically, we were conducting classes about rescue techniques when we were told of the planes hitting the World Trade Center.” Williams’ team is one of the first response groups to arrive at the site of the Pentagon crash and one of the first to enter the building following the attack. [Connection Newspapers, 9/5/2002] A previous MASCAL (mass casualty) training exercise was held at Fort Belvoir a little over two months earlier (see June 29, 2001). It was “designed to enhance the first ready response in dealing with the effects of a terrorist incident involving an explosion.” [MDW News Service, 7/5/2001] Located at Fort Belvoir is Davison Army Airfield, from where UH-1 “Huey” and UH-60 Black Hawk helicopters fly. Davison’s mission includes maintaining “a readiness posture in support of contingency plans,” and providing “aviation support for the White House, US government officials, Department of Defense, Department of the Army, and other government agencies.” [Pentagram, 5/7/1999; Military District of Washington, 8/2000]

A number of pilots with the 102nd Fighter Wing at Otis Air National Guard Base in Massachusetts are preparing to take off for a training mission and see two of their unit’s fighter jets being scrambled in response to the hijacked Flight 11, but they are not asked to respond to the emerging crisis themselves and continue with their preparations for the training mission. [102nd Fighter Wing, 2001; Richard, 2010, pp. 9-12]
Pilots Preparing for Training over the Atlantic - The pilots are preparing to fly a defensive counter-air mission in an area of military training airspace over the Atlantic Ocean, southeast of Long Island, known as “Whiskey 105.” [Richard, 2010, pp. 10, 12; Airman, 9/3/2011] According to most accounts, six of the 102nd Fighter Wing’s F-15 fighters will be participating in the training mission. [102nd Fighter Wing, 2001; North American Aerospace Defense Command, 9/11/2001; Cape Cod Times, 9/11/2006; Spencer, 2008, pp. 155] But Major Martin Richard, one of the pilots involved, will write in a 2010 book that eight of the unit’s F-15s take part in the mission. Richard will recall that after the coordination briefing for the training mission, he goes to the “life support shop” and puts on his flying gear, and then goes to the operations desk. There, the unit’s supervisor of flying, Lieutenant Colonel Jon Treacy, briefs the pilots preparing for the training mission on current weather and airfield updates, and gives them the status of a KC-135 tanker plane that will be refueling their fighters during the training mission. Richard then heads to his F-15, inspects it, and speaks to his crew chief.
Pilots Notice Commotion as Fighters Are Scrambled - As Richard starts his fighter’s engines, he notices a commotion on one side of the flight line ramp. He will recall: “The broken, disjointed communication over the ultra high frequency (UHF) radio indicated confusion. Members of the 102nd Security Forces Squadron, the cops, marshaled into protective positions. Two vehicles appeared with their blue emergency lights flashing. We all knew what was going on.” The 102nd Fighter Wing keeps a pair of F-15s on alert—armed, fueled up, and ready to take off within minutes of a scramble order—and, Richard will recall, “[T]he alert aircraft were being scrambled.” [Richard, 2010, pp. 10-11]
Pilots Watch Alert Fighters Take Off, but Unconcerned about This - The pilots preparing to take off for the training mission idle their engines and wait while the two alert fighters take off (see 8:46 a.m. September 11, 2001). [102nd Fighter Wing, 2001] Richard will describe: “I watched from my jet as the clamshell doors on the alert hangars opened, heard the alert jets’ engines whine to life, and saw them aggressively emerge from the facility like an eager predator in search of its prey. Suddenly, the command post announced, ‘Scramble!’ They blasted off, shattering the previously still, calm, peaceful morning.” [Richard, 2010, pp. 12] The pilots involved in the training mission are apparently unaware of why these fighters are being scrambled. [Cape Cod Times, 9/11/2006] Richard will recall: “I wasn’t too concerned when I saw the scrambled aircraft take off. We see many scrambles during the year and most all are just aircraft or vessels that can’t be identified but are friendly.” [102nd Fighter Wing, 2001]
Pilots Continue Preparing for Training - Once the two alert fighters are airborne, the pilots on the ground continue preparing for their training mission. “Back on the flight line,” Richard will recall, “I arranged my formation for takeoff and followed the standard procedures en route to our training area southwest of Martha’s Vineyard.” [Richard, 2010, pp. 12] Richard and the other pilots will begin their training mission in Whiskey 105 (see (9:00 a.m.-9:24 a.m.) September 11, 2001). They will only learn of the first crash at the World Trade Center and be recalled to their base at around 9:25 a.m. (see (9:25 a.m.-9:45 a.m.) September 11, 2001), and some of them will take off again to help protect US airspace, but that will only be after the terrorist attacks have ended (see (10:30 a.m.) September 11, 2001 and (Shortly After 10:30 a.m.) September 11, 2001). [102nd Fighter Wing, 2001; 9/11 Commission, 10/14/2003 ; Spencer, 2008, pp. 244-246]
Unit's Mission Is to Protect Northeast US - The 102nd Fighter Wing at Otis Air Base, according to its own statement, has aircraft and their crews “on continuous 24-hour, 365-day alert to guard our skies.” The unit says its “mission is to protect the Northeast United States from armed attack from another nation, terrorist attack, and activities such as smuggling, illicit drug activity, and illegal immigration.” Its large area of responsibility includes “the major industrial centers of Boston, New York, Philadelphia, Detroit, and all national command centers in Washington, DC.” [Cape Cod Times, 9/12/2001] The 102nd Fighter Wing is equipped with 18 F-15 Eagles, including the two that are kept on alert. [Boston Globe, 9/15/2001; Cape Cod Times, 9/21/2001]
