At the FAA’s Cleveland Center, an air traffic controller hears a transmission, presumably made by Flight 93 hijacker-pilot Ziad Jarrah, stating: “Ladies and gentlemen: Here the captain, please sit down, keep remaining sitting. We have a bomb on board. So, sit.” [9/11 Commission, 7/24/2004, pp. 12; 9/11 Commission, 8/26/2004, pp. 39] As the 9/11 Commission later notes, “Like [Mohamed] Atta on Flight 11, Jarrah apparently did not know how to operate the communication radios; thus his attempts to communicate with the passengers were broadcast on the [air traffic control] channel.” [9/11 Commission, 8/26/2004, pp. 98] While this communication is assumed to have come from Flight 93, an early FAA report states that it came “from an unknown origin.” [Federal Aviation Administration, 9/17/2001 pdf file] According to Newsweek, just prior to the communication, Cleveland Center controllers heard the sound of screaming from the flight. [Newsweek, 9/22/2001] The 9/11 Commission states that, around the time of the transmission, the plane’s cockpit voice recording indicates “that a woman, most likely a flight attendant, was being held captive in the cockpit. She struggled with one of the hijackers who killed or otherwise silenced her.” [9/11 Commission, 7/24/2004, pp. 12; 9/11 Commission, 8/26/2004, pp. 39] Though the Cleveland air traffic controller understands the hijacker’s communication, he responds to it: “Calling Cleveland Center, you’re unreadable. Say again, slowly.” He also notifies his supervisor who passes the information up the chain of command, and the FAA’s Command Center is subsequently informed, “United 93 may have a bomb on board.” At 9:34 the Command Center will relay this information to FAA headquarters (see 9:34 a.m. September 11, 2001).

According to the 9/11 Commission, word of Flight 93’s hijacking reaches FAA headquarters. By this time, headquarters has established an open line of communication with the FAA Command Center at Herndon, Virginia. It had instructed the center to poll all flight control centers about suspect aircraft. So, at this time, the Command Center passes on Cleveland’s message: “United 93 may have a bomb on board.” The FAA headquarters apparently does not forward this information to the military, despite having the responsibility for doing so. Ben Sliney, the FAA’s national operations manager at its Herndon Command Center, will later recount, “I do know that all the information was being relayed to headquarters and, at least as far as we were concerned, it should have been. We thought it had been given to the military at each juncture.” The Command Center continually updates FAA headquarters on Flight 93 until it crashes. [9/11 Commission, 6/17/2004; CBC, 9/12/2006]

Military officers at the FAA’s Command Center are informed of the hijacking of Flight 93, according to the FAA’s National Operations Manager Ben Sliney. If such notification is given, it is presumably shortly after the Command Center learns of the hijacking (see 9:34 a.m. September 11, 2001). Sliney will later tell the 9/11 Commission: “Available to us at the Command Center of course is the military cell, which was our liaison with the military services. They were present at all of the events that occurred on 9/11.” He will add, “The normal protocols for the events that were transpiring then—that is to say hijacked aircraft, which requires a notification to NORAD—those, at least I was given to understand, were made promptly—the notifications on each hijack.” The FAA’s acting Deputy Administrator Monte Belger will add: “[T]here were military people on duty at the FAA Command Center, as Mr. Sliney said. They were participating in what was going on. There were military people in the FAA’s Air Traffic Organization in a situation room. They were participating in what was going on.” [9/11 Commission, 6/17/2004] If the cell is notified, it is unclear what, if anything, the military liaison officers—Colonel John Czabaranek, Lieutenant Colonel Michael-Anne Cherry, and Major Kevin Bridges (see (Between 9:04 a.m. and 9:25 a.m.) September 11, 2001)—at the Command Center do with the information about Flight 93’s hijacking. The 9/11 Commission will say that the first notification to the military about Flight 93 comes at 10:07 a.m. (see 10:05 a.m.-10:08 a.m. September 11, 2001).

The FAA’s Cleveland Center notifies the FAA’s Great Lakes Regional Operations Center about the screams and statements it heard from an unknown origin, but that are believed to have come from Flight 93. These transmissions were heard between 9:28 and 9:39 (see (9:28 a.m.) September 11, 2001, (9:32 a.m.) September 11, 2001 and (9:39 a.m.) September 11, 2001). [Federal Aviation Administration, 9/17/2001 pdf file] The FAA’s Herndon Command Center and Washington headquarters were alerted to Flight 93 several minutes earlier (see 9:34 a.m. September 11, 2001).

United Airlines official Sandy Rogers calls Ellen King at the FAA’s Command Center to discuss Flight 93. The timing of the call is not known specifically, although it appears to be after the Pentagon was hit and could not be long after Flight 93 is thought to have crashed, which is shortly after 10:00 a.m. (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001). Rogers tells King that Flight 93 has been hijacked, and King responds, “Oh God… thank you,” indicating she was previously unaware of the hijacking. However, the FAA had been aware of the situation since a few minutes after the hijacking took place (see (9:33 a.m.) September 11, 2001 and 9:34 a.m. September 11, 2001). Rogers also says: “It’s over Hagerstown now and you’re not aware of it. It’s heading toward Washington, DC, and we are under a threat of a hijacking on board and this flight is out of our control now heading toward Washington, DC.” Rogers states that United Airlines is “advising the military” about the plane and King also says that the FAA will do the same. [Federal Aviation Administration, 10/14/2003, pp. 37-39 pdf file] However, there are no other reports of Flight 93 ever being over Hagerstown, which is in Maryland. Flight 93 is said to crash in Shanksville, Pennsylvania, and is thought never to reach Maryland. There will be some—apparently mistaken—reports that the plane is still airborne after it is thought to have crashed (see (Between 10:10 a.m. and 10:15 a.m.) September 11, 2001 and 10:10 a.m.-10:11 a.m. September 11, 2001), and this may be another such report.

The military liaison at the FAA’s Cleveland Center calls NORAD’s Northeast Air Defense Sector (NEADS) and alerts it to the hijacked Flight 93. According to the 9/11 Commission, this is the first notification NEADS receives about Flight 93, but it comes too late, since the plane has already crashed (see (10:06 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 30; 9/11 Commission, 8/26/2004, pp. 46]
'Bomb on Board' Flight 93 - At 10:05 a.m., the military liaison at the Cleveland Center, who is unaware that Flight 93 has just crashed, calls NEADS to inform it that Flight 93 is heading toward Washington, DC. Even though communicating with NEADS is not one of his responsibilities, he wants to make sure it is in the loop. [Spencer, 2008, pp. 224] At NEADS, the call is answered by Tech Sergeant Shelley Watson. Shortly into the call, at 10:07, the military liaison tells her: “We got a United 93 out here. Are you aware of that?” He continues, “That has a bomb on board.” Watson asks: “A bomb on board? And this is confirmed? You have a mode three [beacon code], sir?” The military liaison replies, “No, we lost his transponder” (see (9:40 a.m.) September 11, 2001). The news about Flight 93 is shouted out to Major Kevin Nasypany, the NEADS mission crew commander. Nasypany responds: “Gimme the call sign. Gimme the whole nine yards.… Let’s get some info, real quick. They got a bomb?”
Liaison Wants Fighters Sent toward Flight 93 - The military liaison continues, asking Watson if NEADS scrambled fighter jets in response to Delta 1989, an aircraft that was mistakenly reported as having been hijacked (see (9:28 a.m.-9:33 a.m.) September 11, 2001 and 9:39 a.m. September 11, 2001). Watson replies: “We did. Out of Selfridge and Toledo” (see (9:55 a.m.) September 11, 2001 and 10:01 a.m. September 11, 2001), and says these jets are airborne. When the military liaison asks if the fighters can be directed to where Flight 93 is, Watson asks him if the Cleveland Center has latitude and longitude coordinates for this aircraft. The military liaison replies that he has not got this information available right now. All he knows is that Flight 93 has “got a confirmed bomb on board… and right now, his last known position was in the Westmoreland area.… Which is… in the Pittsburgh, Pennsylvania, area.” [North American Aerospace Defense Command, 9/11/2001; Vanity Fair, 8/1/2006]
NEADS Searches on Radar - The news of a bomb on board Flight 93 spreads quickly at NEADS, and personnel there search for the aircraft’s primary return on their radar screens. But because the plane has already crashed, they will be unable to locate it. NEADS will only learn that Flight 93 has crashed at 10:15 a.m., during a call with the FAA’s Washington Center (see 10:15 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 30-31]
FAA Failed to Notify Military Earlier - The Cleveland Center’s notification to NEADS about Flight 93 comes 39 minutes after the plane was hijacked (see (9:28 a.m.) September 11, 2001) and 33 minutes after FAA headquarters was alerted to the hijacking (see 9:34 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 11, 28] At the time NEADS is alerted to Flight 93, NORAD is similarly uninformed about this aircraft, according to the 9/11 Commission. The Commission will state, “At 10:07, its representative on the air threat conference call stated that NORAD had ‘no indication of a hijack heading to DC at this time.’” According to the Commission, the National Military Command Center (NMCC) at the Pentagon learned about the Flight 93 hijacking slightly earlier on, at 10:03 a.m. (see 10:03 a.m. September 11, 2001). However, the NMCC was notified by the White House, not the FAA. [9/11 Commission, 7/24/2004, pp. 42] A former senior FAA executive, speaking on condition of anonymity, will later try to explain why it takes the FAA so long to alert NEADS to Flight 93. He will say, “Our whole procedures prior to 9/11 were that you turned everything [regarding a hijacking] over to the FBI.” [Vanity Fair, 8/1/2006] Yet military instructions contradict this, stating, “In the event of a hijacking, the NMCC will be notified by the most expeditious means by the FAA.” [US Department of Defense, 7/31/1997 pdf file; US Department of Defense, 6/1/2001 pdf file]
NORAD Commanders Claim Earlier Awareness of Flight 93 - Two senior NORAD officials will contradict the 9/11 Commission’s conclusion, and claim they were aware of Flight 93 well before it crashed (see Shortly Before 9:36 a.m. September 11, 2001 and (9:36 a.m.-10:06 a.m.) September 11, 2001). [Filson, 2003, pp. 68, 71-73] Colonel Robert Marr, the NEADS battle commander, will tell the Commission that, while the flight was still airborne, “his focus was on UAL 93, which was circling over Chicago,” and he “distinctly remembers watching the flight UAL 93 come west, and turn over Cleveland.” [9/11 Commission, 10/27/2003 pdf file; 9/11 Commission, 1/23/2004 pdf file] Major General Larry Arnold, the commander of the Continental US NORAD Region, will recall, “[W]e watched the [Flight] 93 track as it meandered around the Ohio-Pennsylvania area and started to turn south toward DC.” [Filson, 2003, pp. 71]
