Air Traffic Control (12)


(8:24 am) September 11, 2001: Boston Air Traffic Controllers Hear Flight 11 Hijacker Say, 'We Have Some Planes,' but Uncertain of Origin of Transmission 

Because the talkback button on Flight 11 has been activated, Boston Center air traffic controllers can hear a hijacker on board say to the passengers: “We have some planes. Just stay quiet and you’ll be OK. We are returning to the airport.” [Boston Globe, 11/23/2001; 9/11 Commission, 7/24/2004, pp. 19 Air traffic controller Pete Zalewski recognizes this as a foreign, Middle Eastern-sounding voice, but does not make out the specific words “we have some planes.” He responds, “Who’s trying to call me?” Seconds later, in the next transmission, the hijacker continues: “Nobody move. Everything will be OK. If you try to make any moves you’ll endanger yourself and the airplane. Just stay quiet.” [New York Times, 10/16/2001; 9/11 Commission, 6/17/2004; MSNBC, 9/9/2006] Bill Peacock, the FAA director of air traffic services, later claims, “We didn’t know where the transmission came from, what was said and who said it.” David Canoles, the FAA’s manager of air traffic evaluations and investigations, adds: “The broadcast wasn’t attributed to a flight. Nobody gave a flight number.” [Washington Times, 9/11/2002] Similarly, an early FAA report will state that both these transmissions came from “an unknown origin.” [Federal Aviation Administration, 9/17/2001] Zalewski asks for an assistant to help listen to the transmissions coming from the plane, and puts its frequency on speakers so others at Boston Center can hear. Because Zalewski didn’t understand the initial hijacker communication from Flight 11, the manager of Boston Center instructs the center’s quality assurance specialist to “pull the tape” of the transmission, listen to it carefully, and then report back. They do this, and by about 9:03 a.m. a Boston manager will report having deciphered what was said in the first hijacker transmission (see 9:03 a.m. September 11, 2001). [9/11 Commission, 6/17/2004; MSNBC, 9/9/2006] Fellow Boston controller Don Jeffroy also hears the tape of the hijacker transmissions, though he doesn’t state at what time. He says: “I heard exactly what Pete [Zalewski] heard. And we had to actually listen to it a couple of times just to make sure that we were hearing what we heard.” [MSNBC, 9/11/2002] At some point, Ben Sliney, the national operations manager at the FAA’s Herndon Command Center, gets word of the “We have some planes” message, and later says the phrase haunts him all morning. American Airlines Executive Vice President for Operations Gerard Arpey is also informed of the “strange transmissions from Flight 11” at some point prior to when it crashes at 8:46 a.m. [USA Today, 8/12/2002] Boston Center will receive a third transmission from Flight 11 about ten minutes later (see 8:34 a.m. September 11, 2001).


(8:25 am) September 11, 2001: Boston Center Starts Notifying Chain of Command 

Boston flight control begins notifying the chain of command that a suspected hijacking of Flight 11 is in progress. Those notified include the center’s own facility manager, the FAA’s New England Regional Operations Center (ROC) in Burlington, Massachusetts, and the FAA Command Center in Herndon, Virginia. [Federal Aviation Administration; 9/11 Commission, 8/26/2004, pp. 11] According to the 9/11 Commission, this is consistent with FAA protocol: “From interviews of controllers at various FAA centers, we learned that an air traffic controller’s first response to an aircraft incident is to notify a supervisor, who then notifies the traffic management unit and the operations manager in charge. The FAA center next notifies the appropriate regional operations center (ROC), which in turn contacts FAA headquarters.” [9/11 Commission, 7/24/2004, pp. 458] But according to Ben Sliney, the national operations manager at the FAA’s Command Center, “the protocol was in place that the center that reported the hijacking would notify the military.… I go back to 1964, where I began my air traffic career, and they have always followed the same protocol.” [9/11 Commission, 6/17/2004] Yet Boston Center supposedly will not contact NORAD about Flight 11 until about 12 minutes later (see (8:37 a.m.) September 11, 2001). Already about ten minutes have passed since controllers first noticed a loss of contact with Flight 11 (see 8:15 a.m. September 11, 2001). Boston reportedly also contacts several other air traffic control centers about the suspected hijacking at this time (see 8:25 a.m. September 11, 2001).


(8:37 am) September 11, 2001: Boston Center Notifies NEADS of Hijacking, against Normal Procedures; Accounts Conflict over Timing 

The FAA’s Boston Center calls NORAD’s Northeast Air Defense Sector (NEADS) in Rome, NY, to alert it to the suspected hijacking of Flight 11. According to the 9/11 Commission, this is “the first notification received by the military “at any level” that American 11 had been hijacked.” [9/11 Commission, 7/24/2004, pp. 20; 9/11 Commission, 8/26/2004, pp. 13] The call is made by Joseph Cooper, an air traffic controller at the Boston Center, and answered by Jeremy Powell, a technical sergeant on the NEADS operations floor. [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 25] Beginning the call, Cooper says: “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.” Powell replies, “Is this real-world or exercise?” Cooper answers, “No, this is not an exercise, not a test.” [9/11 Commission, 7/24/2004, pp. 20] Shortly into the call, Powell passes the phone on to Lieutenant Colonel Dawne Deskins. Deskins identifies herself to Cooper, and he tells her, “We have a hijacked aircraft and I need you to get some sort of fighters out here to help us out.” [Newhouse News Service, 1/25/2002; ABC News, 9/11/2002; Bamford, 2004, pp. 8; Spencer, 2008, pp. 26]

Military Claims Call Goes against Procedure - The 1st Air Force’s official history of the response to the 9/11 attacks will later suggest that Boston Center is not following normal procedures when it makes this call to NEADS. It states: “If normal procedures had taken place Powell probably wouldn’t have taken that phone call. Normally, the FAA would have contacted officials at the Pentagon’s National Military Command Center who would have contacted the North American Aerospace Defense Command. The secretary of defense would have had to approve the use of military assets to assist in a hijacking, always considered a law enforcement issue.” The only explanation it gives for this departure from protocol is that “nothing was normal on Sept. 11, 2001, and many say the traditional chain of command went by the wayside to get the job done.” [Filson, 2003, pp. 51]

Accounts Conflict over Time of Call - There will be some conflict between different accounts, as to when this vital call from Boston Center to NEADS occurs. An ABC News documentary will indicate it is made as early as 8:31 a.m. [ABC News, 9/11/2002] Another ABC News report will state, “Shortly after 8:30 a.m., behind the scenes, word of a possible hijacking [reaches] various stations of NORAD.” [ABC News, 9/14/2002] NEADS logs indicate the call occurs at 8:40 a.m., and NORAD will report this as the time of the call in a press release on September 18, 2001. [Federal Aviation Administration, 9/17/2001; North American Aerospace Defense Command, 9/18/2001] The 8:40 time will be widely reported in the media prior to the 9/11 Commission’s 2004 report. [Associated Press, 8/21/2002; BBC, 9/1/2002; CNN, 9/11/2002] But tape recordings of the NEADS operations floor that are referred to in the 9/11 Commission Report place the call at 8:37 and 52 seconds. [9/11 Commission, 7/24/2004, pp. 20; Vanity Fair, 8/1/2006] If the 8:37 a.m. time is correct, this would mean that air traffic controllers have failed to successfully notify the military until approximately 12 minutes after they became certain that Flight 11 had been hijacked (see 8:25 a.m. September 11, 2001), 16 minutes after Flight 11’s transponder signal was lost, and 24 minutes after the plane’s pilots made their last radio contact. [9/11 Commission, 6/17/2004] At 8:34, the Boston Center tried contacting the military through the FAA’s Cape Cod facility, which is located on Otis Air National Guard Base, but was told that it needed to call NEADS. [9/11 Commission, 7/24/2004, pp. 20; Spencer, 2008, pp. 22]


(8:46 am) September 11, 2001: New York Center Air Traffic Controllers Notice Problems with Flight 175 

After being focused on Flight 11, Dave Bottiglia, an air traffic controller at the FAA’s New York Center, first notices problems with Flight 175. [MSNBC, 9/11/2002; 9/11 Commission, 7/24/2004, pp. 21] Both Flight 11 and Flight 175 have been in the airspace that Bottiglia is responsible for monitoring. Bottiglia has just watched Flight 11’s radar blip disappear, which means the plane has dipped below his radar’s coverage area, so is below 2,000 feet. But he does not yet realize it has crashed. He says aloud, “Well, we know he’s not high altitude anymore.” [MSNBC, 9/11/2002; Spencer, 2008, pp. 37] Around this time, Flight 175’s transponder changes twice in the space of a minute (see 8:46 a.m.-8:47 a.m. September 11, 2001).

Conflicting Accounts - According to MSNBC, “within seconds” of losing Flight 11’s blip, “Bottiglia has another unexpected problem.” While looking for Flight 11, he realizes that Flight 175 is also missing, and “instinctively… knows the two [planes] are somehow related.” He asks another controller to take over all of his other planes. [MSNBC, 9/11/2002] But according to the 9/11 Commission’s account, Bottiglia is still trying to locate Flight 11 after it crashes, and so it is not until 8:51 a.m. that he notices the problem with Flight 175. [9/11 Commission, 8/26/2004, pp. 21]

‘An Intruder over Allentown’ - Around the time Flight 175 changes its transponder code, air traffic controller Curt Applegate, who is sitting at the radar bank next to Bottiglia’s, sees a blip that might be the missing Flight 11. He shouts out: “Look. There’s an intruder over Allentown.” According to the Washington Post, “In air traffic jargon, an ‘intruder’ is a plane with an operating transponder that has entered restricted airspace without permission.” In fact, it is the missing Flight 175. [Washington Post, 9/17/2001; MSNBC, 9/11/2002] However, these accounts make no mention of NORAD being notified about the problems with Flight 175 at this time. But according to a NORAD timeline released shortly after 9/11, NORAD’s Northeast Air Defense Sector (NEADS) was alerted about Flight 175 by the FAA several minutes earlier, at 8:43 a.m. [North American Aerospace Defense Command, 9/18/2001]


(8:51 am - 8:53 am) September 11, 2001: Air Traffic Controller Declares Flight 175 as Possibly Hijacked 

According to the 9/11 Commission, Dave Bottiglia, the air traffic controller handling Flight 175, only notices now that this flight’s transponder signal has changed (see 8:46 a.m.-8:47 a.m. September 11, 2001). Bottiglia asks Flight 175 to return to its proper transponder code. There is no response. Beginning at 8:52 a.m., he makes repeated attempts to contact it, but there is still no response. Bottiglia contacts another controller at 8:53 a.m., and says: “We may have a hijack. We have some problems over here right now. I can’t get a hold of UAL 175 at all right now and I don’t know where he went to.” [New York Times, 10/16/2001; 9/11 Commission, 6/17/2004; Spencer, 2008, pp. 48] This account apparently conflicts with earlier accounts that claim NORAD’s Northeast Air Defense Sector (NEADS) was notified at 8:43 a.m. that Flight 175 had been hijacked (see 8:43 a.m. September 11, 2001). [North American Aerospace Defense Command, 9/18/2001]


(8:56 am) September 11, 2001: Flight 77's Transponder Signal Disappears, yet NEADS Is Not Alerted 

Flight 77’s transponder is turned off, meaning that the aircraft’s speed, altitude, and flight information are no longer visible on radar displays at the FAA’s Indianapolis Center. [Federal Aviation Administration, 9/17/2001; National Transportation Safety Board, 2/19/2002; 9/11 Commission, 7/24/2004, pp. 9] The Indianapolis Center air traffic controller in charge of Flight 77 watched the plane go off course and head southwest before its data disappeared from his radar screen. He looks for primary radar signals along the aircraft’s projected flight path as well as in the airspace where it had started to turn, but cannot find it. [9/11 Commission, 6/17/2004] He tries contacting the plane repeatedly, saying “American 77, Indy,” and: “American 77, Indy, radio check. How do you read?” But there is no response. [New York Times, 10/16/2001; New York Times, 10/16/2001]

NEADS Not Contacted - US News and World Report will later comment, ”[E]xperts say that an airliner making a 180-degree turn followed by a transponder turnoff should have been a red flag to controllers.” It will quote Robert Cauble, a 20-year veteran of Navy air traffic control, who says: “The fact that the transponder went off, they should have picked up on that immediately. Everyone should have been on alert about what was going on.” [US News and World Report, 10/8/2001] Yet the Indianapolis Center supposedly does not notify NORAD’s Northeast Air Defense Sector (NEADS). According to the 9/11 Commission, NEADS will only learn that Flight 77 is missing at 9:34 a.m. (see 9:34 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 26-27]

Controller Thinks Plane Suffered Mechanical Failure - While several air traffic control centers were reportedly informed of the Flight 11 hijacking as early as 8:25 a.m. (see 8:25 a.m. September 11, 2001), according to the 9/11 Commission, the controller handling Flight 77 does not realize other aircraft have been hijacked, and he is unaware of the situation in New York. He mistakenly assumes Flight 77 has experienced an electrical or mechanical failure. [Guardian, 10/17/2001; 9/11 Commission, 6/17/2004] After he informs other Indianapolis Center personnel of the developing situation, they will clear all other aircraft from the plane’s westerly route so their safety will not be affected if Flight 77 is still flying along its original path but unable to be heard. [Freni, 2003, pp. 29; 9/11 Commission, 7/24/2004, pp. 460; 9/11 Commission, 8/26/2004, pp. 30]

Airline and Possibly Pentagon Learn of Flight 77 Problems - While NEADS is not alerted about the errant aircraft, a controller at the Indianapolis Center will contact American Airlines at 8:58 to inform it that contact has been lost with Flight 77 (see 8:58 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 30] And an article in the New York Times will indicate that the Pentagon’s National Military Command Center (NMCC) promptly becomes aware of the problems with Flight 77 (see (Shortly After 8:51 a.m.) September 11, 2001). [New York Times, 9/15/2001]


(9:09 am - 9:13 am) September 11, 2001: Otis Fighters Remain in Holding Pattern over Ocean instead of Defending New York City 

The two F-15 fighter jets launched from Otis Air National Guard Base in response to Flight 11 (see 8:46 a.m. September 11, 2001) have been directed to “Whiskey 105,” a military airspace training area over the Atlantic Ocean, just south of Long Island. According to the 9/11 Commission, “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.” [9/11 Commission, 7/24/2004, pp. 20; Spencer, 2008, pp. 85] Otis pilot Major Daniel Nash will later comment, “Neither the civilian controller or the military controller knew what they wanted us to do.” [Cape Cod Times, 8/21/2002]

‘Pushback’ from FAA Controllers - By 9:08 a.m., Major Kevin Nasypany, the NEADS mission crew commander, had learned of the second World Trade Center crash and wanted to send the Otis fighters to New York City. However, according to Vanity Fair, the NEADS “weapons techs get ‘pushback’ from civilian FAA controllers, who have final authority over the fighters as long as they are in civilian airspace. The FAA controllers are afraid of fast-moving fighters colliding with a passenger plane, of which there are hundreds in the area, still flying normal routes.” [9/11 Commission, 8/26/2004, pp. 25; Vanity Fair, 8/1/2006] Author Lynn Spencer will add: ”[L]ocal FAA controllers are busy shutting down New York’s airspace and are less than eager to grant the fighters access to the civilian airspace. They’re afraid of fast-moving fighters colliding with the hundreds of airliners that are still in the area. Many of those flights are doing unpredictable things just now, such as canceling their flight plans and changing course, and controllers are not convinced that they can provide adequate separation if fast-moving fighters are added to the mix. They just need a few more minutes, they keep saying.”

New York Center Not Answering Phone - Nasypany tries contacting the military liaison at the FAA’s New York Center, but no one is answering the phone. According to Spencer, “He wants the Otis fighters over New York, not in military airspace 100 miles off the coast, but he has little choice. Without permission from the FAA to penetrate the civil airspace over New York, NEADS must advise the Otis F-15 pilots… to continue to remain clear of the city.” [Spencer, 2008, pp. 111-112]

Director Wants Jets ‘Closer In’ - At 9:10 a.m., the senior director on the NEADS operations floor tells the weapons director, “I want those fighters closer in.” [9/11 Commission, 7/24/2004, pp. 459] NEADS weapons controller Major Steve Hedrick asks Major James Fox, the weapons team leader, “Can we give [the fighters] a mission?” Fox replies, “Right now their mission is to hold.” [Spencer, 2008, pp. 111] Then, at around 9:11 a.m., either the senior weapons director at NEADS or his technician instructs the Otis fighters to “remain at current position [holding pattern] until FAA requests assistance.”

Fighters Exit Holding Pattern for New York - Just before 9:13 a.m., the Otis pilots tell their controller at the FAA’s Boston Center that they need to establish a combat air patrol over New York. [9/11 Commission, 7/24/2004, pp. 459] According to the 9/11 Commission, “Radar data show that at 9:13, when the Otis fighters were about 115 miles away from the city, the fighters exited their holding pattern and set a course direct for Manhattan” (see 9:13 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 24]


(9:21 am) September 11, 2001: Boston Air Traffic Control Center Mistakenly Tells NEADS Flight 11 Is Still Airborne 

According to the 9/11 Commission, NEADS is contacted by the FAA’s Boston Center. Colin Scoggins, Boston Center’s military liaison, tells it: “I just had a report that American 11 is still in the air, and it’s on its way towards—heading towards Washington.… That was another—it was evidently another aircraft that hit the tower. That’s the latest report we have.… I’m going to try to confirm an ID for you, but I would assume he’s somewhere over, uh, either New Jersey or somewhere further south.” The NEADS official asks: “He—American 11 is a hijack?… And he’s heading into Washington?” Scoggins answers yes both times and adds, “This could be a third aircraft.” Somehow Boston Center has been told by FAA headquarters that Flight 11 is still airborne, but the 9/11 Commission will say it hasn’t been able to find where this mistaken information came from.

Scoggins Makes Error - Vanity Fair magazine will later add, “In Boston, it is Colin Scoggins who has made the mistaken call.” Scoggins will explain why he believes he made this error: “With American Airlines, we could never confirm if [Flight 11] was down or not, so that left doubt in our minds.” He says he was monitoring a conference call between FAA centers (see 8:28 a.m. September 11, 2001), “when the word came across—from whom or where isn’t clear—that American 11 was thought to be headed for Washington.” However, Boston Center was never tracking Flight 11 on radar after losing sight of it near Manhattan: “The plane’s course, had it continued south past New York in the direction it was flying before it dipped below radar coverage, would have had it headed on a straight course toward DC. This was all controllers were going on.” Scoggins says, “After talking to a supervisor, I made the call and said [American 11] is still in the air.” [Northeast Air Defense Sector, 9/11/2001; 9/11 Commission, 6/17/2004; Vanity Fair, 8/1/2006]

Myers Refers to Mistaken Report - In the hours following the attacks, acting Chairman of the Joint Chiefs of Staff Richard Myers will apparently refer to this erroneous report that Flight 11 is still airborne and heading toward Washington, telling the Associated Press that “prior to the crash into the Pentagon, military officials had been notified that another hijacked plane had been heading from the New York area to Washington.” Myers will say “he assumed that hijacked plane was the one that hit the Pentagon, though he couldn’t be sure.” [Associated Press, 9/11/2001]


(9:28 am) September 11, 2001: Cleveland Flight Control Hears Sounds of Struggle as Flight 93 Is Hijacked

According to the 9/11 Commission, less than a minute after Flight 93 acknowledged a routine radio transmission from the FAA’s Cleveland Center (see 9:27 a.m. September 11, 2001), John Werth—the controller handling the flight—and pilots of other aircraft in the vicinity of Flight 93 hear “a radio transmission of unintelligible sounds of possible screaming or a struggle from an unknown origin.” [9/11 Commission, 6/17/2004; CBS News, 9/10/2006] Someone, presumably Flight 93’s pilot Jason Dahl, is overheard by controllers as he shouts, “Mayday!” [New York Times, 7/22/2004] Seconds later, the controller responds, “Somebody call Cleveland?” Then there are more sounds of screaming and someone yelling, “Get out of here, get out of here.” [Newsweek, 9/22/2001; Observer, 12/2/2001; MSNBC, 7/30/2002; 9/11 Commission, 6/17/2004] Then the voices of the hijackers can be heard talking in Arabic. The words are later translated to show they are talking to each other, saying, “Everything is fine.” [Newsweek, 12/3/2001] Later, passenger phone calls will describe two dead or injured bodies just outside the cockpit; presumably these are the two pilots. [New York Times, 7/22/2004]


(9:32 am) September 11, 2001: Flight 93 Hijacker Tells Passengers Bomb Is Onboard; Air Traffic Controller Overhears 

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] 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). [9/11 Commission, 7/24/2004, pp. 28]


(10:05 am - 10:08 am) September 11, 2001: NEADS Alerted to Flight 93, Reportedly for the First Time 

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; US Department of Defense, 6/1/2001]

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; 9/11 Commission, 1/23/2004] 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]


(12:16 pm) September 11, 2001: US Airspace Cleared of All Civilian Aircraft 

US airspace is clear of all civilian air traffic, with the exception of a small number of law enforcement and emergency operations aircraft. Otherwise, only military aircraft are airborne. [Federal Aviation Administration, 9/18/2001; Federal Aviation Administration, 4/15/2002; USA Today, 8/12/2002] The FAA’s Command Center in Herndon, Virginia, announces that the airspace has been successfully shut down. [Spencer, 2008, pp. 269] At 9:26 a.m., the Command Center ordered a national ground stop that prevented any aircraft from taking off (see 9:26 a.m. September 11, 2001), and at 9:45 a.m. it ordered FAA facilities to instruct all aircraft to land at the nearest airport (see 9:45 a.m. September 11, 2001). Since then, about 4,500 commercial and general aviation aircraft have landed without incident. This is the first time ever that all civilian aircraft in the United States have been grounded. [US Congress. House. Committee On Transportation And Infrastructure, 9/21/2001; Federal Aviation Administration, 3/21/2002; 9/11 Commission, 7/24/2004, pp. 29] Author Pamela Freni will later comment that this clearing of the skies was “a tremendous feat accomplished by a huge team that had never even practiced this part of the game before.” Frank Hatfield, the air traffic division manager for the FAA’s eastern region, will comment: “What we did on September 11 was done amazingly well. It was almost like World War II, the way the airplanes were handled.” [Freni, 2003, pp. 69] At 12:30 p.m., the FAA will report that there are 50 flights in US airspace, but none of them are reporting any problems.
