The 9/11 Commission Report
From Chapter 1, sections 1.1 and 1.2

These sections of chapter one detail the hijacking of American Airlines Flight 11 as it left Logan Airport in Boston for Los Angeles until it crashed into the North Tower of The World Trade Center at 8:46 AM, and the homeland defense reaction to the hijacking. [note: where possible, recordings of the actual aircraft/air traffic control transmissions have been inserted in the appropriate places]

From Chapter 1, Section 1:
The Hijacking of American 11
American Airlines Flight 11 provided nonstop service from Boston to Los Angeles. On September 11, Captain John Ogonowski and First Officer Thomas McGuinness piloted the Boeing 767. It carried its full capacity of nine flight attendants. Eighty-one passengers boarded the flight with them (including
the five terrorists).

The plane took off at 7:59. Just before 8:14, it had climbed to 26,000 feet, not quite its initial assigned cruising altitude of 29,000 feet. All communications and flight profile data were normal. About this time the “Fasten Seatbelt” sign would usually have been turned off and the flight attendants would have begun
preparing for cabin service.

At that same time, American 11 had its last routine communication with the ground when it acknowledged navigational instructions from the FAA’s air traffic control (ATC) center in Boston. Sixteen seconds after that transmission, ATC instructed the aircraft’s pilots to climb to 35,000 feet. That message and all subsequent attempts to contact the flight were not acknowledged. From this and other evidence, we believe the hijacking began at 8:14 or shortly thereafter.

Reports from two flight attendants in the coach cabin, Betty Ong and Madeline “Amy” Sweeney, tell us most of what we know about how the hijacking happened. As it began, some of the hijackers—most likely Wail al Shehri and Waleed al Shehri,who were seated in row 2 in first class—stabbed the two unarmed flight attendants who would have been preparing for cabin service.

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. Ong speculated that they had “jammed their way” in. 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.

At the same time or shortly thereafter, Atta—the only terrorist on board trained to fly a jet—would have moved to the cockpit from his business-class seat, possibly accompanied by Omari.As this was happening, passenger Daniel Lewin, who was seated in the row just behind Atta and Omari,was stabbed by one of the hijackers—probably Satam al Suqami, who was seated directly behind Lewin. Lewin had served four years as an officer in the Israeli military. He may have made an attempt to stop the hijackers in front of him, not realizing that another was sitting behind him.

The hijackers quickly gained control and sprayed Mace, pepper spray, or some other irritant in the first-class cabin, in order to force the passengers and flight attendants toward the rear of the plane.They claimed they had a bomb.

About five minutes after the hijacking began, Betty Ong contacted the American Airlines Southeastern Reservations Office in Cary, North Carolina, via an AT&T airphone to report an emergency aboard the flight. This was the first of several occasions on 9/11 when flight attendants took action outside the scope of their training, which emphasized that in a hijacking, they were to communicate with the cockpit crew. The emergency call lasted approximately 25 minutes, as Ong calmly and professionally relayed information about events taking place aboard the airplane to authorities on the ground.

At 8:19, Ong reported: “The cockpit is not answering, somebody’s stabbed in business class—and I think there’s Mace—that we can’t breathe—I don’t know, I think we’re getting hijacked.” She then told of the stabbings of the two flight attendants.

At 8:21, one of the American employees receiving Ong’s call in North Carolina, Nydia Gonzalez, alerted the American Airlines operations center in Fort Worth,Texas, reaching Craig Marquis, the manager on duty. Marquis soon realized this was an emergency and instructed the airline’s dispatcher responsible for the flight to contact the cockpit. At 8:23, the dispatcher tried unsuccessfully to contact the aircraft. Six minutes later, the air traffic control specialist in American’s operations center contacted the FAA’s Boston Air Traffic Control Center about the flight. The center was already aware of the problem.

Boston Center knew of a problem on the flight in part because just before 8:25 the hijackers had attempted to communicate with the passengers. The microphone was keyed, and immediately one of the hijackers said, “Nobody move. Everything will be okay. If you try to make any moves, you’ll endanger yourself and the airplane. Just stay quiet.” Air traffic controllers heard the transmission; Ong did not. The hijackers probably did not know how to operate the cockpit radio communication system correctly, and thus inadvertently broadcast their message over the air traffic control channel instead of the cabin
public-address channel.

Also at 8:25, and again at 8:29, Amy Sweeney got through to the American Flight Services Office in Boston but was cut off after she reported someone was hurt aboard the flight. Three minutes later, Sweeney was reconnected to the office and began relaying updates to the manager, Michael Woodward.

At 8:26, Ong reported that the plane was “flying erratically.” A minute later, Flight 11 turned south. American also began getting identifications of the hijackers, as Ong and then Sweeney passed on some of the seat numbers of those who had gained unauthorized access to the cockpit.

Sweeney calmly reported on her line that the plane had been hijacked; a man in first class had his throat slashed; two flight attendants had been stabbed—one was seriously hurt and was on oxygen while the other’s wounds seemed minor; a doctor had been requested; the flight attendants were unable to contact the cockpit; and there was a bomb in the cockpit. Sweeney told Woodward that she and Ong were trying to relay as much information as they could to people on the ground.

At 8:38, Ong told Gonzalez that the plane was flying erratically again. Around this time Sweeney told Woodward that the hijackers were Middle Easterners, naming three of their seat numbers. One spoke very little English and one spoke excellent English. The hijackers had gained entry to the cockpit, and she did not know how. The aircraft was in a rapid descent.

At 8:41, Sweeney told Woodward that passengers in coach were under the impression that there was a routine medical emergency in first class. Other flight attendants were busy at duties such as getting medical supplies while Ong and Sweeney were reporting the events.

At 8:41, in American’s operations center, a colleague told Marquis that the air traffic controllers declared Flight 11 a hijacking and “think he’s [American 11] headed toward Kennedy [airport in New York City]. They’re moving everybody out of the way. They seem to have him on a primary radar. They seem to think that he is descending.”

At 8:44, Gonzalez reported losing phone contact with Ong. About this same time Sweeney reported to Woodward, “Something is wrong. We are in a rapid descent . . .we are all over the place.” Woodward asked Sweeney to look out the window to see if she could determine where they were. Sweeney responded: “We are flying low. We are flying very, very low. We are flying way too low.” Seconds later she said, “Oh my God we are way too low.” The phone call ended.

At 8:46:40, American 11 crashed into the North Tower of the World Trade Center in New York City. All on board, along with an unknown number of people in the tower, were killed instantly.


From Chapter 1, Section 2:
American Airlines Flight 11
FAA Awareness. Although the Boston Center air traffic controller realized at an early stage that there was something wrong with American 11, he did not immediately interpret the plane’s failure to respond as a sign that it had been hijacked. At 8:14, when the flight failed to heed his instruction to climb to 35,000 feet, the controller repeatedly tried to raise the flight. He reached out to the pilot on the emergency frequency. Though there was no response, he kept trying to contact the aircraft.

At 8:21, American 11 turned off its transponder, immediately degrading the information available about the aircraft. The controller told his supervisor that he thought something was seriously wrong with the plane, although neither suspected a hijacking. The supervisor instructed the controller to follow standard procedures for handling a “no radio” aircraft. The controller checked to see if American Airlines could establish communication with American 11. He became even more concerned as its route changed, moving into another sector’s airspace. Controllers immediately began to move aircraft out of its path, and asked other aircraft in the vicinity to look for American 11.

At 8:24:38, the following transmission came from American 11:

American 11: We have some planes. Just stay quiet, and you’ll be okay. We are returning to the airport.

The controller only heard something unintelligible; he did not hear the specific words “we have some planes.” The next transmission came seconds later:

American 11: Nobody move. Everything will be okay. If you try to make any moves, you’ll endanger yourself and the airplane. Just stay quiet.

The controller told us that he then knew it was a hijacking. He alerted his supervisor, who assigned another controller to assist him. He redoubled his efforts to ascertain the flight’s altitude. Because the controller didn’t understand the initial transmission, the manager of Boston Center instructed his quality assurance specialist to “pull the tape” of the radio transmission, listen to it closely, and report back.

Between 8:25 and 8:32, in accordance with the FAA protocol, Boston Center managers started notifying their chain of command that American 11 had been hijacked. At 8:28, Boston Center called the Command Center in Herndon to advise that it believed American 11 had been hijacked and was heading toward
New York Center’s airspace.

By this time, American 11 had taken a dramatic turn to the south. At 8:32, the Command Center passed word of a possible hijacking to the Operations Center at FAA headquarters. The duty officer replied that security personnel at headquarters had just begun discussing the apparent hijack on a conference call with the New England regional office. FAA headquarters began to follow the hijack protocol but did not contact the NMCC to request a fighter escort.

The Herndon Command Center immediately established a teleconference between Boston, New York, and Cleveland Centers so that Boston Center could help the others understand what was happening.

At 8:34, the Boston Center controller received a third transmission from American 11:

American 11: Nobody move please. We are going back to the airport. Don’t try to make any stupid moves.

In the succeeding minutes, controllers were attempting to ascertain the altitude of the southbound flight.

Military Notification and Response. Boston Center did not follow the protocol in seeking military assistance through the prescribed chain of command. In addition to notifications within the FAA, Boston Center took the initiative, at 8:34, to contact the military through the FAA’s Cape Cod facility. The center also tried to contact a former alert site in Atlantic City, unaware it had been phased out. At 8:37:52, Boston Center reached NEADS. This was the first notification received by the military—at any level—that American 11 had been hijacked:

FAA: Hi. Boston Center TMU [Traffic Management Unit], we have a problem here.We have a hijacked aircraft headed towards New York, and we need you guys to,we need someone to scramble some F-16s
or something up there, help us out.

NEADS: Is this real-world or exercise?

FAA: No, this is not an exercise, not a test.

NEADS ordered to battle stations the two F-15 alert aircraft at Otis Air Force Base in Falmouth, Massachusetts, 153 miles away from New York City. The air defense of America began with this call.

At NEADS, the report of the hijacking was relayed immediately to Battle Commander Colonel Robert Marr. After ordering the Otis fighters to battle stations, Colonel Marr phoned Major General Larry Arnold, commanding general of the First Air Force and NORAD’s Continental Region. Marr sought authorization to scramble the Otis fighters. General Arnold later recalled instructing Marr to “go ahead and scramble them, and we’ll get authorities later.” General Arnold then called NORAD headquarters to report.

F-15 fighters were scrambled at 8:46 from Otis Air Force Base. But NEADS did not know where to send the alert fighter aircraft, and the officer directing the fighters pressed for more information: “I don’t know where I’m scrambling these guys to. I need a direction, a destination.” Because the hijackers had turned off the plane’s transponder, NEADS personnel spent the next minutes searching their radar scopes for the primary radar return. American 11 struck the North Tower at 8:46. Shortly after 8:50, while NEADS personnel were still trying to locate the flight, word reached them that a plane had hit the World Trade Center.

Radar data show the Otis fighters were airborne at 8:53. Lacking a target, they were vectored toward military-controlled airspace off the Long Island coast. To avoid New York area air traffic and uncertain about what to do, the fighters were brought down to military airspace to “hold as needed.” From 9:09
to 9:13, the Otis fighters stayed in this holding pattern.

In summary, NEADS received notice of the hijacking nine minutes before it struck the North Tower. That nine minutes’ notice before impact was the most the military would receive of any of the four hijackings.
