September 11, 2001 Timeline

Tuesday, September 11, 2001 dawns warm and nearly cloudless in the eastern United States. Millions of men and women ready themselves for work. Some make their way to the Twin Towers, the signature structures of the World Trade Center complex in New York City. Others go to Arlington, Virginia, to the Pentagon. Across the Potomac River, the United States Congress is back in session. At the other end of Pennsylvania Avenue, people begin to line up for a White House tour. In Sarasota, Florida, President George W. Bush goes for an early morning run.1 It is an ordinary late summer day.

The day is perfect for flying, what some pilots call “severe clear”. According to the Federal Aviation Administration, “peak summer traffic demands had diminished and air traffic controllers were expecting a routine, on-time day.”2 Thousands of passengers board commercial aircraft, heading for business meetings, returning home from conferences, meeting friends or family for vacations. Among the many aircraft preparing to fly on that Tuesday morning are four flights which will be boarded by 19 passengers carrying weapons and a plan to hijack the planes and use them as missiles to destroy targets in New York City and Washington D.C. It is an attack against America. The flights are:

American Airlines Flight 11 – Boston, MA to Los Angeles, CA – a Boeing 767 with 81 passengers and 11 crew members; take-off time: 7:59 a.m.

United Airlines Flight 175 – Boston, MA to Los Angeles, CA – a Boeing 767 with a 56 passengers and 9 crew members; take-off time: 8:14 a.m.

American Airlines Flight 77 – Washington, D.C. to Los Angeles, CA – a Boeing 757 with 58 passengers and 6 crew members; take-off time: 8:20 a.m.

United Airlines Flight 93 – Newark, NJ to San Francisco, CA – a Boeing 757 with 37 passengers and 7 crew members; take-off time: 8:42 a.m.3

(Times indicated are Eastern Standard Time)

The following timeline focuses primarily on events related to United Airlines Flight 93, the plane which did not strike the terrorists’ intended target. Events on board Flight 11 and Flight 175 are identified as relating to the attacks at the World Trade Center. Events on board Flight 77 are identified as relating to the attack at the Pentagon. The events of September 11, 2001 were unprecedented and complex. The reporting of these events has been conflicting. New information about the attacks and the response to the attacks continues to be released. This timeline is based on the most complete information available at this time, and will be revised or updated as new information becomes available.

9:21 am: Confusion regarding Flight 11 leads to military action
The nation’s Air Traffic Control System and the military struggle to deal with an unprecedented multiple hijacking in which planes are used as weapons. They receive an erroneous report that Flight 11 has not crashed into the World Trade Center, but instead is still airborne and on a course for Washington, D.C. In response, fighter jets are scrambled from Langley Air Force Base, but without orders to engage. In fact, the fighter pilots are not aware of the hijackings.42

Hijackers wearing red bandanas around their foreheads, break into the cockpit of Flight 93 as it flies over eastern Ohio. Flight 93 suddenly drops 685 feet in altitude. Cleveland Center hears the first of two radio transmissions from an unidentified aircraft. During the first broadcast, the captain or first officer declares “Mayday” amid the sounds of a physical struggle in the cockpit. The second radio transmission, 35 seconds later, indicates that the fight is continuing. The captain or first officer is heard shouting, “Hey get out of here—get out of here—get out of here.”48 Noticing that Flight 93 has made an unauthorized altitude change, the controller, John Werth, suspects that the transmission originated with that flight. He asks, “Somebody call Cleveland?”49
9:29 am: Cleveland Center tries to reach Flight 93
Controller John Werth continues calling Flight 93, “United ninety-three, verify three-five-zero (thirty-five thousand feet).” There is no reply. Werth makes numerous attempts to contact Flight 93 without receiving any acknowledgement. Controllers at Cleveland Center move other aircraft away from Flight 93 due to the lack of acknowledgement. Several other aircraft on the frequency confirm hearing unusual sounds of an unknown origin.50

An out-of-breath hijacker, probably Jarrah, makes this announcement which was heard and recorded by Air Traffic Control: “Ladies and Gentlemen: Here the captain, please sit down keep remaining sitting. We have a bomb on board. So, sit.” Jarrah then programmed the plane’s autopilot to turn the aircraft around and head east.52 The cockpit voice recorder also captures the voice of a woman, most likely a flight attendant, who is held captive in the cockpit. Based on this overheard transmission, Cleveland Center reports to the Herndon Command Center (FAA) that Flight 93 may have a bomb on board.53

9:33 am: Controller and Dispatcher attempt contact with Flight 93
Cleveland Center, responding to the radio transmission from the hijacked plane, asks, “We just, ah, we didn’t get it clear . . . Is that United Ninety Three calling?” A new text warning message from United Airlines is sent to Flight 93 and other aircraft: “Highsecurity alert. Secure cockpit.”54

NORAD (North American Air Defense) broadcasts this message: “Vice President has cleared to us to intercept tracks of interest and shoot them down if they do not respond.” The NEADS commander did not pass this order along to the fighter pilots circling over New York and Washington because the commander was unsure how the pilots would, or should, proceed with this guidance. 107

6:00 pm: Governor Ridge views Flight 93 crash site, holds press conference
Pennsylvania Governor Tom Ridge, after assessing the Flight 93 crash site, holds a news conference: “It’s difficult to describe the range of emotions everyone feels when they not only learn about these incidents today, but they’ve actually seen them. The dictionary is inadequate, and there just aren’t enough words. But I guess the range of emotions goes from rage and anger to sorrow to horror to, I guess, a sense of nausea that we all feel.”111 He calls on Pennsylvanians to give their prayers, their blood and their talent. He was affected most by what he cannot see: “the most telling site is a large, gaping hole. Very little debris is visible.”112 He promised “a forceful and appropriate response” to those responsible for the “irrational, cowardly, despicable, unconscionable, and immoral” actions that caused United Airlines Flight 93 to crash near Shanksville.113

Terrorist attacks can shake the foundations of our biggest buildings, but they cannot touch the foundation of America. These acts shatter steel, but they cannot dent the steel of American resolve . . . . America and our friends and allies join with all those who want peace and security in the world, and we stand together to win the war against terrorism. This is a day when all Americans from every walk of life unite in our resolve for justice and peace . . . . None of us will ever forget this day, yet we go forward to defend freedom and all that is good and just in our world.”114

This is the opening paragraph of the 9/11 Commission Report. All references to the 9/11 Commission Report in this timeline refer to the 2006 edition of the report which includes the Third Monograph, “The Four Flights and Civil Aviation Security.” This document was re-released in September, 2005 absent many of the initial redactions, following a review undertaken by the Administration at the request of the 9/11 Public Discourse Project, a non-profit organization founded by the former 9/11 Commissioners, to continue the work of the Commission.

According to the Canadian Broadcasting Corporation’s program, “The Fifth Estate”, Jarrah mailed an incorrectly addressed farewell letter to Senguen on September 10. When the letter was returned to the United States it was discovered by FBI investigators. Translated from German, it contains the phrases, “I did not flee from you, but did what I was supposed to do. You ought to be very proud, because it is an honor and you will see the result(s) and everybody will be happy.” (Canadian Broadcasting Corporation, “The Fifth Estate”, “The Pilot – The Story of Ziad Jarrah, originally aired October 10, 2001, updated January 19, 2005.

The letter was found in the suitcase of Mohamed Atta which did not make the transfer from his first flight from Portland, ME to Boston, MA and therefore was not on board Flight 11 when it crashed into the World Trade Center. The letter was found in the vehicle of Nawaf Alhazmi in the parking lot at Dulles International Airport, the departure point for Flight 77 which later crashed into the Pentagon. Finally, the letter was recovered at the Flight 93 crash site.

100 9/11 Commission Report, 46. In the course of its research, the staff of the 9/11 Commission identified inaccuracies in the official testimony given to the Commission by the Department of Defense (DoD) and the Federal Aviation Administration (FAA) in regard to the timeline of events on September 11, 2001.

These erroneous statements first appeared in press releases, testimony before Congress, and reports compiled by the agencies in the days after the crash and were repeated in print and television interviews, books and films over the next several years, including the Air Force official history of September 11, Air War Over America. Specifically, the Commission identified the following four erroneous statements: 1.

The FAA notified the DoD at 9:16 a.m. of the United Flight 93 hijacking. The actual time was 10:07 a.m.;

  1. The FAA notified DoD at 9:24 a.m. of the American Flight 77 hijacking. The actual time was 9:34 a.m.;

  2. DoD scrambled fighters from Langley Air Force Base in response to the hijackings of United Flight 93 and American Flight 77. The fighters were actually scrambled in response to an erroneous report that American Flight 11 was heading south toward Washington, D.C.; 4. DoD was tracking United Flight 93 and intended to intercept the aircraft if it approached Washington, D.C. DoD was not aware of the United Flight 93 hijacking until after the flight crashed. The Inspector General of the Department of Defense verified these inaccuracies in the record and the testimony in a Memorandum released on September 12, 2006. The Inspector General attributes the inaccurate statements to “a lack of capabilities and thoroughness within DoD to accurately reconstruct the response to the sequence of events of September 11, 2001.” Both DoD and the FAA provided the public and the Commission with corrected information, but confusion remains due to the wide distribution of the earlier, inaccurate timelines. The 9/11 Commission Report clearly links its findings to logs maintained that day by the military and the FAA.
