At some time shortly before 10 a.m.—as early as 9:40 a.m. according to one report—air traffic manager Dennis Fritz, in the control tower at Johnstown-Cambria County Airport, 70 miles east of Pittsburgh, receives a call from Cleveland Air Traffic Control reporting a large, suspicious aircraft about 20 miles south of them, descending below six thousand feet. Despite the clear day, Fritz and his colleagues can see no plane approaching through binoculars. Soon afterwards, in response to another call from Cleveland, Fritz orders trainees and custodial staff to evacuate the tower, yet he is still unable to see any plane approaching. Less than a minute later, though, Cleveland calls a third time, saying to disregard the evacuation: The plane has turned south and they have lost radar contact with it. [Pittsburgh Post-Gazette, 9/12/2001; Knight Ridder, 9/13/2001; Pittsburgh Post-Gazette, 10/28/2001; Longman, 2002, pp. 197] Wells Morrison is the agent in charge of the FBI’s Mon Valley Resident Agency, a satellite of its Pittsburgh field office. He too receives a phone call informing him of this flight, though he doesn’t say whom it is from. He contacts the Johnstown FBI office and instructs its agents to head to the Johnstown Airport. [Kashurba, 2002, pp. 109-110] Flight 93 crashes around 10:03 a.m. or soon thereafter (see (10:03 a.m.-10:10 a.m.) September 11, 2001), going down in a field just 14 miles south of Johnstown.

] However, the plane can be—and is—tracked using primary radar by Cleveland flight controllers and at United headquarters. Altitude can no longer be determined, except by visual sightings from other aircraft. The plane’s speed begins to vary wildly, fluctuating between 600 and 400 mph before eventually settling around 400 mph. [Longman, 2002, pp. 77, 214; 9/11 Commission, 6/17/2004 ]
9:40 a.m. September 11, 2001: FAA Command Center Identifies Ten Possible Hijacked Planes
Newark, New Jersey, air traffic controller Bob Varcadipane is talking on the phone with the FAA Command Center. He is told that the Command Center is still suspicious of at least ten planes for one reason or another, all possible hijackings. [MSNBC, 9/11/2002]
9:41 a.m.-9:42 a.m. September 11, 2001: Mysterious White Jet Seen Circling above the White House
Several television networks interrupt their coverage of events in New York to report that a mysterious white aircraft is circling over the White House and the Capitol. 
At 9:41 a.m., Peter Jennings of ABC News reports that “there is a plane circling the White House at the moment. And they’re clearing the grounds there.… And this plane circling the White House adds to the trauma that people are feeling today, but we have no idea precisely what the means.” [ABC News, 9/11/2001] At 9:52 a.m., CNN correspondent John King, who is standing about 200 yards from the White House, says: “About 10 minutes ago, there was a white jet circling overhead. Now, you generally don’t see planes in the area over the White House. That is restricted air space. No reason to believe that this jet was there for any nefarious purposes, but the Secret Service was very concerned, pointing up at the jet in the sky. It is out of sight now, best we can tell.” [CNN, 9/11/2001] Another CNN correspondent, Kate Snow, also reports seeing a plane at around this time, “circling over the Capitol.” She says: “Now whether that may have been an Air Force plane, it’s unclear. But that seemed to be the reason, according to security guards that I talked with, towards the evacuation of the Capitol.” [CNN, 9/11/2001] (The Capitol is reportedly evacuated at 9:48 a.m. (see 9:48 a.m. September 11, 2001). [Fox News, 9/11/2003] ) At 9:55 a.m., NBC News turns to a live report from its correspondent Bob Kur, who recalls: “And in the most surreal of this morning’s scenes here at the White House, a white plane, a very big jet, was flying an unusual pattern near the White House over Lafayette Park, very slowly. It made one circle and then we have not seen it since. There was a lot of concern about what that plane might be. But, again, it’s only speculation, but most people say that since flights have been cleared from US air space, and it was a totally white plane, looked unusual to all of us, that it was a government plane of some kind.” [NBC 4, 9/11/2001]
A CNN comparison between video footage of this plane and an official Air Force photograph will suggest it is an E-4B. This is a militarized version of a Boeing 747 that is used as a flying command post. An E-4B has in fact just been launched from Andrews Air Force Base, just outside Washington, DC (see (9:27 a.m.) September 11, 2001), so this could plausibly be the same plane as is witnessed by the reporters. Two government sources familiar with the incident will later tell CNN the plane was a military aircraft, but that its details are classified. Even by 2007, the Pentagon, FAA, and Secret Service will have offered no public explanation for this plane over the White House. [Verton, 2003, pp. 143-144; CNN, 9/12/2007] In 2009, John Farmer, the former senior counsel to the 9/11 Commission, will claim that this “mystery plane” is an E-4B with the call sign “Venus 77” that takes off from Andrews Air Force Base at around 9:45 a.m. (see (9:45 a.m.) September 11, 2001). [Farmer, 2009, pp. 206-207, 372]
Between 9:41 a.m. and 9:50 a.m. September 11, 2001: Langley Jets Heading in Wrong Direction, Redirected to Washington
A weapons director at NORAD’s Northeast Air Defense Sector (NEADS) notices that the three F-16s launched from Langley Air Force Base (see (9:25 a.m.-9:30 a.m.) September 11, 2001) are going in the wrong direction, and so he contacts them to get them on the correct course.
Citino Thinks FAA Has Redirected Fighters – The weapons director, Master Sergeant Steve Citino, recently forwarded coordinates to the jets, sending them to Washington, DC. However, according to author Lynn Spencer, he inadvertently gave them incorrect coordinates (see 9:40 a.m. September 11, 2001). Now, shortly afterwards, Citino notices that the jets are going in the wrong direction. However, he does not realize his mistake with the coordinates, and instead assumes that the FAA’s Washington Center has redirected the jets so as to avoid air traffic. [Spencer, 2008, pp. 180-181] He makes this assumption even though NEADS recently declared AFIO (Authorization for Interceptor Operations) for Washington airspace, thereby giving the military authority over the FAA for that airspace (see 9:36 a.m. September 11, 2001). [Spencer, 2008, pp. 113, 150]
Fighters Given Correct Destination – Citino radios one of the three Langley AFB pilots, Captain Craig Borgstrom, and gives him the correct course heading. Citino adds: “Just to reiterate. You are under AFIO control! Take all direction from Huntress!” (“Huntress” is the call sign for NEADS.) Borgstrom acknowledges the order, but mentions that the new heading conflicts with the coordinates he has just been given. He says, “We’re showing a CAP [combat air patrol] point of 250 [heading], 20 miles.” Citino snaps back at him: “Negative! That’s incorrect! The CAP is 312, 20 miles!” Borgstrom then relays the correct coordinates to his lead pilot, Major Dean Eckmann, and the three Langley jets set off toward their new destination. [Spencer, 2008, pp. 181]
9:41 a.m.-10:06 a.m. September 11, 2001: Cleveland Center Controller Tracks Flight 93
Cleveland Center air traffic controller Bill Keaton is responsible for guiding high-altitude flights in the airspace where Flight 93 turned off its transponder (see (9:40 a.m.) September 11, 2001). After its transponder goes off, he follows Flight 93 on his radar scope as it travels across his sector, headed toward Washington, DC, and is instructed not to let any other aircraft come within 20 miles of it. Because its transponder is off, Keaton cannot tell the plane’s altitude. He sees it disappear from his scope at the time it crashes. [USA Today, 8/11/2002; Cleveland Free Times, 9/6/2006]
After 9:40 a.m. September 11, 2001: Officials at White House Bothered by TV and Video Conference Technical Problems
Government officials in the Presidential Emergency Operations Center (PEOC) below the White House are frustrated at technical problems they have with the televisions in the center, which mean they are unable to get audio from both the TV broadcast channels and the videoconferencing system at the same time. [White House, 11/1/2001; Newsweek, 12/30/2001] Two large television screens are built into a wall of the PEOC conference room, and, according to journalist and author Stephen Hayes, for most of the day one of them is tuned to CNN and the other to the Fox News Channel. Hayes will write, “Watching the uninterrupted news coverage not only provided new and timely information; it also allowed officials in the shelter [i.e. the PEOC] to understand, as they designed their public response, what exactly the American people were seeing.” [Hayes, 2007, pp. 337, 342]
Officials Have Problems with Television and Video Conference Audio – But, National Security Adviser Condoleezza Rice will later recall, the “only frustration” among those in the PEOC is “that we kept having trouble getting the TV to work.… [W]e were having trouble with the, some of the video link.” Therefore, “if you were trying to do the video conference, you had trouble doing TV.” [White House, 11/1/2001] The “video conference” Rice refers to is presumably the White House video teleconference being conducted by counterterrorism chief Richard Clarke (see (9:10 a.m.) September 11, 2001 and 9:25 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 36] Anna Perez, Rice’s communications counselor, will add, “[Y]ou couldn’t do the SVTS [secure video teleconference system] at the same time you could do the CNN.” [White House, 11/1/2001] Eric Edelman, a member of Vice President Dick Cheney’s staff, will recall: “[T]he video conference that Dick Clarke was chairing was going on.… [W]e could see that, so that was on the screen, we could follow that. Not always with audio… sometimes with audio, sometimes not.” [White House, 10/25/2001] According to Hayes, however, the problem is in fact that “[a]lthough the two televisions on the wall could be tuned to different channels, they could get audio from only one.” Consequently, “On several occasions, the officials could see notices of ‘breaking news’ without being able to hear the details of those updates.” [Hayes, 2007, pp. 342]
‘Everybody’ in PEOC Frustrated by TV Problem – Rice will recall that the problem with the televisions is “kind of frustrating to everybody.” [White House, 11/1/2001] One unnamed official will recall that Cheney, who is in the PEOC for much of the day, is “cranked up” about the problem and repeatedly demands that it be fixed. [Hayes, 2007, pp. 342] Mary Matalin, a counselor to Cheney, will recall, “You can have sound on one or the other [i.e. the TV broadcasts or the video teleconference], and [Cheney] found that technically imperfect.” [CNN, 9/11/2002; CNN, 9/14/2002] According to Newsweek, this is the only thing that causes Cheney’s composure to break and leads to him showing any irritation while he is in the PEOC. [Newsweek, 12/30/2001]
Accounts Conflict over Whether Problem Is Fixed – It is unclear whether this technical problem with the televisions gets fixed. According to Perez, PEOC personnel are able to fix it. “It took them a little while, but they did get it together. They got it right,” she will say. [White House, 11/1/2001] But according to Hayes, the problem remains unfixed. [Hayes, 2007, pp. 342] Clarke will later give a different account of the problem with getting audio from television broadcasts and the video conference simultaneously. He will write that when he goes down to the PEOC sometime around midday (see (Shortly Before 12:30 p.m.) September 11, 2001), Army Major Mike Fenzel complains to him, “I can’t hear the crisis conference because Mrs. Cheney [Lynne Cheney, the wife of the vice president] keeps turning down the volume on you so she can hear CNN.” [Clarke, 2004, pp. 18]
Shortly After 9:40 a.m. September 11, 2001: DC Air National Guard Commander Wherley Wants Orders from Someone More Senior before He Will Launch Fighters
Brigadier General David Wherley, the commander of the District of Columbia Air National Guard (DCANG), speaks to a Secret Service agent over the phone, but declines the agent’s request to launch DCANG fighter jets without first receiving an order to do so from someone more senior. [Spencer, 2008, pp. 184]
Wherley Takes over Call – Wherley has just arrived at the headquarters of the DCANG’s 121st Fighter Squadron at Andrews Air Force Base, near Washington (see (Shortly After 9:39 a.m.) September 11, 2001). At the operations desk there, Major Daniel Caine passed Wherley a phone he was talking over, before heading off to prepare to get airborne. [Filson, 2003, pp. 78; Vogel, 2007, pp. 445]
Caller Wants Jets over Washington – Wherley finds that the caller Caine was speaking with is from the Secret Service. They want the DCANG to put up a combat air patrol (CAP) over Washington. But, according to author Lynn Spencer: “Wherley knows that there has never been a CAP anywhere over this country, much less over Washington. Such a request—coming from someone not even in the military—is unheard of.” Wherley understands the power of the Secret Service, and knows that with its responsibility to protect the president it clearly has some authority over other agencies, including the military. “But still, such an order from a Secret Service agent seems rather far-reaching.” He therefore tells the caller, “I would feel more comfortable receiving such an order from someone higher in the chain of command, preferably in the military.”
Wherley Told to Call ‘Operations Center’ – According to Spencer, the agent gives Wherley “a phone number and tells him to call over to the White House Operations Center, where Vice President [Dick] Cheney has been ushered.” [Spencer, 2008, pp. 184] Presumably the “Operations Center” is the Presidential Emergency Operations Center (PEOC) below the White House, where Cheney is evacuated to by his Secret Service agents (see (Shortly After 9:03 a.m.) September 11, 2001). [ABC News, 9/14/2002; 9/11 Commission, 7/24/2004, pp. 39-40] However, other accounts, including Wherley’s interview with the 9/11 Commission, will state that Wherley subsequently calls someone at the Secret Service’s White House Joint Operations Center (JOC), not the PEOC (see (9:45 a.m.) September 11, 2001). [Filson, 2003, pp. 79; 9/11 Commission, 8/28/2003] (Wherley’s current call is also with an agent at the JOC. [9/11 Commission, 3/8/2004 ; 9/11 Commission, 3/11/2004 ] )
9:41 a.m.-9:48 a.m. September 11, 2001: FAA Command Center Notifies FAA Headquarters about Flight 93 Problems
The FAA’s Command Center in Herndon, Virginia, provides updates to FAA headquarters in Washington, DC, about the problems with Flight 93. At 9:41 a.m., John White, a manager at the Command Center, is talking to Doug Davis, the special assistant for technical operations in air traffic services at FAA headquarters. White says that Flight 93 has reversed course from its intended flight path (see (9:36 a.m.) September 11, 2001), its transponder signal has been lost (see (9:40 a.m.) September 11, 2001), and it is now descending and heading east. From 9:42 a.m., one of the Command Center managers (exactly who is unstated) gives the headquarters several updates on Flight 93’s progress and location. At 9:46 a.m., White tells Jeff Griffith, the FAA’s deputy director of air traffic, that Flight 93 is “29 minutes out of Washington, DC, and tracking toward us.” Two minutes later, in another conversation with Griffith, White confirms that Flight 93 has reversed course and is heading toward Washington.

9:41 a.m. September 11, 2001: Passenger Mark Bingham Makes Two Unsuccessful Attempted Calls from Flight 93
Mark Bingham, a passenger on Flight 93, makes two attempts at calling his mother, Alice Hoglan, from the plane after his previous call with her was cut off, but both attempts are unsuccessful. [Federal Bureau of Investigation, 9/17/2001; 9/11 Commission, 5/13/2004 ] Bingham tries making the calls using a GTE Airfone near the back of the plane. [9/11 Commission, 5/13/2004 ; McMillan, 2014, pp. 122] He has just spoken to Hoglan, but the call broke off after less than three minutes (see (9:37 a.m.) September 11, 2001). [Federal Bureau of Investigation, 9/11/2001; 9/11 Commission, 5/13/2004 ] He tries calling her again a minute and a half after that call ended, but dials the wrong number by mistake. He tries calling her once more 33 seconds later, but despite dialing the correct number this time, the attempt is unsuccessful. The first of these unsuccessful calls lasts 0 seconds while the second lasts three seconds, according to information that will later be derived from a study of GTE Airfone records of calls from Flight 93. [9/11 Commission, 5/13/2004 ] Hoglan will make no mention of her phone ringing at the time her son attempts these two calls when she is interviewed by the FBI about her experiences this morning. [Federal Bureau of Investigation, 9/11/2001; Federal Bureau of Investigation, 9/17/2001]
