After air traffic controllers at Washington Dulles International Airport notice an unidentified aircraft, later determined to be Flight 77, approaching Washington on their radar screens (see (Between 9:25 a.m. and 9:30 a.m.) September 11, 2001 and 9:32 a.m. September 11, 2001), they initially think it is a military fighter plane, due to its high speed and the way it is being flown. [ABC News, 10/24/2001; 9/11 Commission, 7/24/2004, pp. 9] Yet the alleged hijacker pilot of Flight 77 has been known for his poor flying skills. [Washington Post, 9/30/2001; New York Times, 5/4/2002]
Aircraft Performs Elaborate Maneuver – The Dulles controllers are unable to identify the plane because its transponder—which transmits identifying information about an aircraft to radar screens—has been turned off (see 8:56 a.m. September 11, 2001). [Washington Post, 9/11/2001; Washington Post, 9/12/2001] It is flying at almost 500 miles per hour while approaching Washington, and then performs a rapid downward spiral, “dropping the last 7,000 feet in two and a half minutes,” before hitting the Pentagon (see 9:34 a.m.- 9:37 a.m. September 11, 2001). [CBS News, 9/21/2001; USA Today, 8/12/2002]
Moving ‘Like a Military Aircraft’ – Controller Danielle O’Brien will later recall: “The speed, the maneuverability, the way that he turned, we all thought in the radar room, all of us experienced air traffic controllers, that that was a military plane. You don’t fly a 757 in that manner. It’s unsafe.” [ABC News, 10/24/2001] Another controller, Todd Lewis, will recall: “[N]obody knew that was a commercial flight at the time. Nobody knew that was American 77.… I thought it was a military flight. I thought that Langley [Air Force Base] had scrambled some fighters and maybe one of them got up there.… It was moving very fast, like a military aircraft might move at a low altitude.” [MSNBC, 9/11/2002]
Alleged Pilot ‘Could Not Fly at All’ – Yet many people who have met Hani Hanjour, the hijacker allegedly at the controls of Flight 77, considered him to be a very poor pilot (see October 1996-December 1997, 1998, February 8-March 12, 2001, and (April-July 2001)). Just a month previously, an airport refused to rent him a single-engine Cessna plane because instructors there found his flying skills so weak (see Mid-August 2001). [Gazette (Greenbelt), 9/21/2001; Newsday, 9/23/2001] And an employee at a flight school Hanjour attended earlier in the year will later comment: “I’m still to this day amazed that he could have flown into the Pentagon. He could not fly at all” (see January-February 2001). [New York Times, 5/4/2002]
9:32 a.m. September 11, 2001: Dulles Airport Controllers Notice Flight 77 Approaching, According to 9/11 Commission
At 9:32 a.m., according to the 9/11 Commission, several air traffic controllers at Washington Dulles International Airport notice a fast-moving target, which is later determined to be Flight 77, heading eastbound on their radar screens. [9/11 Commission, 7/24/2004, pp. 25; 9/11 Commission, 8/26/2004, pp. 33] At the Terminal Radar Approach Control (TRACON) at Dulles Airport, which is 22 miles west of the Pentagon, controllers have been searching for primary radar targets since 9:21, when the facility was notified of the loss of contact with Flight 77 (see 9:21 a.m. September 11, 2001). [USA Today, 9/13/2001; Navy Times, 9/22/2001; 9/11 Commission, 7/24/2004, pp. 25]
Controllers See Fast-Moving Radar Track – They now notice an unidentified blip on their screens, heading toward the White House at unusually high speed. [Washington Post, 9/11/2001; Spencer, 2008, pp. 145] Controller Danielle O’Brien will later recall: “I noticed the aircraft. It was an unidentified plane to the southwest of Dulles, moving at a very high rate of speed.… I had literally a blip and nothing more. I slid over to the controller on my left, Tom Howell, and I asked him, ‘Do you see an unidentified plane there southwest of Dulles?’ And his response was, ‘Yes. Oh, my gosh, yes! Look how fast he is.’” According to O’Brien, the aircraft is between 12 and 14 miles away when she notices it. It is heading for what is known as Prohibited Area 56 (P-56), which is the airspace over and near the White House, at a speed of about 500 miles per hour. [ABC, 10/24/2001; ABC News, 10/24/2001; Department of Transportation, 8/4/2005] Because the plane’s transponder has been turned off (see 8:56 a.m. September 11, 2001) its identity and type are presently unknown, and the Dulles controllers initially think it is a military aircraft (see (9:25 a.m.-9:37 a.m.) September 11, 2001). [Washington Post, 9/12/2001; ABC News, 10/24/2001; 9/11 Commission, 7/24/2004, pp. 25]
TRACON Notifies Others – The Dulles TRACON alerts Washington’s Reagan National Airport (see (9:33 a.m.) September 11, 2001) and the Secret Service (see (9:33 a.m.) September 11, 2001) to the approaching aircraft. Its operations supervisor also provides continuous updates over a teleconference that has been established at the FAA’s headquarters. [Federal Aviation Administration, 9/17/2001 
; 9/11 Commission, 7/24/2004, pp. 25] According to an FAA chronology that is published shortly after 9/11, the Dulles TRACON controllers notice the unidentified aircraft earlier than the 9/11 Commission says, at between 9:25 and 9:30 (see (Between 9:25 a.m. and 9:30 a.m.) September 11, 2001). [Federal Aviation Administration, 9/17/2001 ]
9:34 a.m.- 9:37 a.m. September 11, 2001: Flight 77 Flies Complex Near-Circular Loop before Striking Pentagon
Before crashing into the Pentagon, Flight 77 performs a rapid downward spiral, flying almost a complete circle and descending 7,000 feet in two and a half minutes. [CBS News, 9/21/2001]
330-Degree Turn – At 9:34 a.m., Flight 77 is about 3.5 miles west-southwest of the Pentagon. But, at an altitude of around 7,000 feet, it is flying too high to hit its target. [CBS News, 9/21/2001; New York Times, 10/16/2001; National Transportation Safety Board, 2/19/2002 ] Based on an analysis of radar data and information from the plane’s flight data recorder, a 2002 National Transportation Safety Board report will describe the maneuver the aircraft then performs: “[Flight 77] started a right 330-degree descending turn to the right. At the end of the turn, the aircraft was at about 2,000 feet altitude and four miles southwest of the Pentagon. Over the next 30 seconds, power was increased to near maximum and the nose was pitched down in response to control column movements.” The aircraft accelerates to about 530 miles per hour as it closes in on the Pentagon. [National Transportation Safety Board, 2/19/2002 ]
Controllers Watch on Radar – Air Traffic Controllers at Washington Dulles International Airport follow Flight 77 on their radar screens as it performs this maneuver. Danielle O’Brien will later recall: “John, our supervisor, relayed verbatim, ‘OK, he’s 12 miles west, he’s moving very fast eastbound.… Eleven miles west.’ And it was just a countdown. Ten miles west, nine miles west.… And it went six, five, four, and I had it in my mouth to say three, and all of a sudden the plane turned away. In the room it was almost a sense of relief.” [ABC, 10/24/2001; ABC News, 10/24/2001] Todd Lewis will recall that the aircraft “was heading right towards a prohibited area in downtown Washington.… Then it turned south and away from the prohibited area, which seemed like a momentary sigh of relief, and it disappeared. But it was going away from Washington, which seemed to be the right thing.” [MSNBC, 9/11/2002] However, O’Brien will continue: “[T]he plane turned back. He continued in the right-hand turn, made a 360-degree maneuver.… We lost radar contact with that aircraft. And we waited. And we waited.” [ABC, 10/24/2001; ABC News, 10/24/2001]
Maneuver Indicates Advanced Flying Skills – According to CBS News, “The steep turn” made by Flight 77 “was so smooth… sources say, it’s clear there was no fight for control going on.” The “complex maneuver suggests the hijackers had better flying skills than many investigators first believed.” [CBS News, 9/21/2001] Aviation experts will conclude that this maneuver was the work of “a great talent… virtually a textbook turn and landing.” [Washington Post, 9/10/2002] Due to the aircraft’s high speed and the way it is being flown, Dulles Airport controllers mistake it for a military fighter jet (see (9:25 a.m.-9:37 a.m.) September 11, 2001). [Washington Post, 9/12/2001; ABC News, 10/24/2001; MSNBC, 9/11/2002] Yet the hijacker allegedly at the controls, Hani Hanjour, was considered to be a very poor pilot at numerous flight schools he attended (see October 1996-December 1997, 1998, January-February 2001, February 8-March 12, 2001, (April-July 2001), and Mid-August 2001).
