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] )
8:29 a.m. September 11, 2001: American Airlines Makes First Contact with FAA about Flight 11, Learns Details of Crisis
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]
8:33 a.m. September 11, 2001: Information from FAA about Flight 11 Leads American Airlines to Suspect Plane Is Hijacked
Craig Marquis, the manager on duty at the American Airlines System Operations Control (SOC) center in Fort Worth, Texas, is told details of the crisis with Flight 11 that have just been received from the FAA’s Boston Center, and this information leads American Airlines to suspect that Flight 11 has been hijacked. [9/11 Commission, 8/26/2004, pp. 12] Minutes earlier, Marquis instructed Bill Halleck, an air traffic control specialist at the SOC, to contact the Boston Center to find out what was happening with Flight 11, and Halleck has just done so (see 8:29 a.m. September 11, 2001). [9/11 Commission, 1/8/2004 ; 9/11 Commission, 4/26/2004 ] Halleck now calls Marquis and tells him what he learned about Flight 11 from his call with the Boston Center. He says the aircraft is at “29,000 feet. They’ve lost comm [communications] with ‘em. Turned off his transponder. Tracking his primary [radar track] only. Was westbound. Turned southbound. Said the controller heard on the [radio] frequency, the pilot apparently adjust his mike… lot of loud voices… that sounded threatening.” Halleck then tells Marquis the details of this possible threat in the cockpit of Flight 11 that the Boston Center heard over radio. He says, “Something about ‘return or I’ll kill ya,’ or something to that effect… or threatening dialogue.” Halleck adds that he asked the Boston Center to pass on to the SOC “any information or updates” it subsequently receives. After Marquis hears this information from Halleck, he asks Halleck to “pull” Flight 11 up on his aircraft situation display. Following Halleck’s report to Marquis, American Airlines “now suspected that Flight 11 had been hijacked,” according to the 9/11 Commission. [American Airlines, 9/11/2001, pp. 7-19; 9/11 Commission, 8/26/2004, pp. 12]
8:37 a.m.-8:39 a.m. September 11, 2001: Flight 11 Attendant Betty Ong Says Her Plane Is ‘Flying Sideways’ and Descending
Betty Ong, a flight attendant on the hijacked Flight 11, tells American Airlines employees on the ground that her plane is flying erratically, and then says it is in a rapid descent. [American Airlines, 9/11/2001, pp. 7-19; 9/11 Commission, 8/26/2004, pp. 13] Ong is on the phone with employees at the American Airlines Southeastern Reservations Office in North Carolina (see 8:18 a.m. September 11, 2001). One of these employees, Nydia Gonzalez, is simultaneously relaying the information Ong provides to Craig Marquis, the manager on duty at the American Airlines System Operations Control (SOC) center in Texas (see (8:21 a.m.) September 11, 2001). [9/11 Commission, 11/19/2003 ; 9/11 Commission, 8/26/2004, pp. 8-9] Ong reports that all of the passengers on Flight 11 have been moved out of the first class section of the plane, back to the coach section. Gonzalez passes this information on to Marquis.
Ong Says Flight 11 Is ‘Flying Sideways’ – Gonzalez then asks Ong, “What’s going on honey?” Ong previously mentioned that Flight 11 was flying erratically (see 8:25 a.m. September 11, 2001), but she subsequently said it had stabilized (see 8:28 a.m. September 11, 2001). She now says the plane is flying erratically again. [American Airlines, 9/11/2001, pp. 7-19; 9/11 Commission, 8/26/2004, pp. 13] Vanessa Minter, an employee at the reservations office, will later recall that Ong describes the way the plane is being flown by saying it is “flying sideways.” According to Minter, another reservations office employee, Winston Sadler, then asks Ong if she means the plane is flying erratically and Ong says yes. [Federal Bureau of Investigation, 9/12/2001, pp. 38-41] Gonzalez will similarly recall that Ong says the plane is “flying sideways, erratically.” [Federal Bureau of Investigation, 9/12/2001, pp. 69-71] Gonzalez relays the information to Marquis, telling him, “The aircraft is erratic again, flying very erratically.”
Ong Says Flight 11 Is in a Rapid Descent – About a minute later, Gonzalez again asks Ong, “What’s going on?” [American Airlines, 9/11/2001, pp. 7-19] Ong says her plane is descending rapidly. [Federal Bureau of Investigation, 9/11/2001, pp. 1-8; Federal Bureau of Investigation, 9/12/2001, pp. 69-71] Gonzalez passes this information on to Marquis, telling him, “Seems like the aircraft is descending quite a bit right now.” Marquis replies, “Okay, I have it on the radar here.” Marquis then asks Bill Halleck, an air traffic control specialist at the SOC, if Flight 11 is descending. [American Airlines, 9/11/2001, pp. 7-19; 9/11 Commission, 11/19/2003 ] When Halleck recently contacted the FAA’s Boston Center, he was told that air traffic controllers had lost Flight 11’s transponder signal (see 8:29 a.m. September 11, 2001). [9/11 Commission, 3/25/2004, pp. 15] He therefore tells Marquis: “We don’t know [if Flight 11 is descending]. The transponder is off, so we have no active read on him.” [American Airlines, 9/11/2001, pp. 7-19; 9/11 Commission, 11/19/2003 ]
8:40 a.m. September 11, 2001: American Airlines Manager Wants Air Traffic Control to Be Told to Treat Flight 11 as an Emergency
Craig Marquis, the manager on duty at the American Airlines System Operations Control (SOC) center in Fort Worth, Texas, instructs Bill Halleck, an air traffic control specialist at the SOC, to tell FAA air traffic controllers to treat Flight 11 as an emergency. [American Airlines, 9/11/2001, pp. 7-19; 9/11 Commission, 11/19/2003 ; 9/11 Commission, 8/26/2004, pp. 14] Halleck contacted the FAA’s Boston Center at 8:29 a.m. to inquire about Flight 11 (see 8:29 a.m. September 11, 2001), and at 8:33 a.m. he called Marquis and passed on what he had just learned from the Boston Center about the crisis with the aircraft (see 8:33 a.m. September 11, 2001). That information, according to the 9/11 Commission, led American Airlines to suspect that Flight 11 had been hijacked. [9/11 Commission, 8/26/2004, pp. 11-12] Marquis now instructs Halleck, “Tell [air traffic control] to handle this as an emergency.” According to a 9/11 Commission memorandum, “At this point, Marquis was just confirming it was a hijack and he wanted to make sure Halleck was communicating the emergency to the [air traffic control] system.” Halleck answers that FAA controllers are treating Flight 11 as a hijacking, saying, “They have in there, it’s been hijacked.” Marquis replies: “It is. Okay.” Halleck adds that FAA controllers “don’t know what his altitude is… they think he’s descending. They think he’s headed toward Kennedy [JFK International Airport in New York]… they’re moving everybody out of the way.” Referring to Betty Ong, a flight attendant on Flight 11, Marquis tells Halleck, “I’m talking to the flight attendant in the back of the plane and she says the plane is descending.” [American Airlines, 9/11/2001, pp. 7-19; American Airlines, 1/15/2002; 9/11 Commission, 11/19/2003 ]
8:45 a.m. September 11, 2001: American Airlines Managers Told about Flight 11 Problems during Conference Call
American Airlines managers are informed of what their airline has learned about the trouble on Flight 11 during a regular conference call. [Wall Street Journal, 10/15/2001; 9/11 Commission, 11/19/2003 ] In their daily morning conference call, senior American Airlines personnel usually discuss what happened on the previous day at the airline and what they are expecting in the day ahead. [9/11 Commission, 1/7/2004 ] But shortly after today’s conference call begins, Joseph Bertapelle, a manager at the airline’s System Operations Control (SOC) center in Fort Worth, Texas, announces, “Gentlemen, I have some information here I need to relay.” [Wall Street Journal, 10/15/2001] Bertapelle then passes on to the senior managers much of the information about the hijacking of Flight 11 that has been received by SOC employees Craig Marquis and Bill Halleck. Marquis, the manager on duty at the SOC, has been on the phone with a supervisor at the American Airlines Southeastern Reservations Office in North Carolina, who has been relaying to him information she received in a simultaneous phone call with Betty Ong, a flight attendant on Flight 11 (see (8:21 a.m.) September 11, 2001). [9/11 Commission, 11/19/2003 ; 9/11 Commission, 8/26/2004, pp. 8-9] And Halleck, an air traffic control specialist at the SOC, has been in contact with the FAA’s Boston Center, which gave him details of the problems with Flight 11 (see 8:29 a.m. September 11, 2001). [9/11 Commission, 3/25/2004, pp. 15] The conference call apparently only lasts a short time. Craig Parfitt, American Airlines’ managing director of dispatch operations, will later recall that at around 8:55 a.m.—10 minutes after the conference call begins—senior managers are arriving at the System Operations Command Center, located on the floor above the SOC (see (Between 8:40 a.m. and 8:55 a.m.) September 11, 2001). Presumably, some of these managers will have previously been participating in the conference call. [9/11 Commission, 11/19/2003 ]
9:16 a.m.-9:18 a.m. September 11, 2001: American Airlines Contacts FAA; Thinks Flight 77 May Have Hit the WTC
Bill Halleck, an American Airlines air traffic control specialist at the airline’s System Operations Control (SOC) in Fort Worth, Texas, phones an official at the FAA’s Herndon Command Center, to ask about the status of New York City air traffic. During their two-and-a-half minute conversation, Halleck says American thinks Flight 11 crashed into the WTC, and says that Flight 77 is “missing.” Presently, he receives an update from someone else at SOC, indicating that Flight 77 may also have crashed into the WTC (see 9:08 a.m. September 11, 2001). He wonders how it could have gotten to New York, but updates the FAA official on this news. The FAA official replies that the second WTC crash may not have been Flight 77 because “we have another call sign” for that incident. The FAA Command Center is currently uncertain of the identity of either of the planes that hit the Twin Towers, and provides no further information. [9/11 Commission, 8/26/2004, pp. 31 and 94]
