Major General Larry Arnold, the commander of the Continental United States NORAD Region (CONR), participates in a video teleconference with other senior NORAD officials and is therefore unavailable when NORAD’s Northeast Air Defense Sector (NEADS) tries contacting him for authorization to scramble fighter jets in response to the hijacked Flight 11. [Filson, 2002; 9/11 Commission, 5/23/2003; 9/11 Commission, 7/24/2004, pp. 20; Spencer, 2008, pp. 31] Arnold is in the video teleconferencing room at CONR headquarters, at Tyndall Air Force Base, Florida.
Teleconference Discussing ‘Russian Exercise’ – Robert Del Toro, an intelligence officer with the 1st Air Force who is in the room with Arnold, will tell the 9/11 Commission that the teleconference is “about the Russian exercise.” [9/11 Commission, 2/2/2004 
] Del Toro is presumably referring to either the Russian Air Force exercise that NORAD is currently monitoring (see September 9, 2001) or the exercise, Vigilant Guardian, that NORAD is currently running, which reportedly includes a simulated war against Russia (see (8:00 a.m.) September 11, 2001). [North American Aerospace Defense Command, 9/9/2001; Arkin, 2005, pp. 545; Denver Post, 8/28/2011]
NORAD Officials from US and Canada on Teleconference – It is unclear exactly who else is participating in the teleconference. Arnold will tell the 9/11 Commission that as well as “our folks”—presumably referring to some of his colleagues at CONR—it includes “the NORAD staff.” The “NORAD staff” presumably includes officials from NORAD’s operations center in Cheyenne Mountain, Colorado, and its headquarters at Peterson Air Force Base, Colorado. [9/11 Commission, 5/23/2003] Arnold will tell author Leslie Filson that the teleconference includes “the CINC”—presumably meaning General Ralph Eberhart, the commander in chief of NORAD, who is at Peterson Air Force Base—and also officials from the Alaskan NORAD Region (ANR) and the Canadian NORAD Region (CANR). [Filson, 2002; 9/11 Commission, 3/1/2004 ]
Arnold Not Alerted to Hijacking – While Arnold is on the teleconference, NEADS calls CONR to alert him to the suspected hijacking of Flight 11 (see (8:38 a.m.) September 11, 2001), but no one at CONR interrupts the teleconference to fetch him or pass on to him the urgent message from NEADS. Arnold will only learn of the hijacking after the teleconference ends (see (8:40 a.m.) September 11, 2001) and he will then call NEADS back (see (8:42 a.m.) September 11, 2001). [9/11 Commission, 5/23/2003; Spencer, 2008, pp. 31, 38]
8:38 a.m.-8:43 a.m. September 11, 2001: NORAD Personnel Mistake Hijacking for Part of an Exercise
When the FAA’s Boston Center first contacts NORAD’s Northeast Air Defense Sector (NEADS) to notify it of the hijacking of Flight 11 (see (8:37 a.m.) September 11, 2001), personnel there initially mistake the hijacking for a simulation as part of an exercise. 
Lieutenant Colonel Dawne Deskins, mission crew chief for the Vigilant Guardian exercise currently taking place (see (6:30 a.m.) September 11, 2001), will later say that initially she and everybody else at NEADS think the call from Boston Center is part of Vigilant Guardian. [Newhouse News Service, 1/25/2002] Although most of the personnel on the NEADS operations floor have no idea what the day’s exercise is supposed to entail, most previous major NORAD exercises included a hijack scenario. [USA Today, 4/18/2004; Utica Observer-Dispatch, 8/5/2004] The day’s exercise is in fact scheduled to include a simulated hijacking later on. [Vanity Fair, 8/1/2006] Major Kevin Nasypany, the NEADS mission crew commander, had helped design the day’s exercise. Thinking the reported hijacking is part of it, he actually says out loud, “The hijack’s not supposed to be for another hour.” [Vanity Fair, 8/1/2006] In the ID section, at the back right corner of the NEADS operations floor, technicians Stacia Rountree, Shelley Watson, and Maureen Dooley react to the news. Dooley, the leader of the ID section, tells the other members of her team: “We have a hijack going on. Get your checklists. The exercise is on” (see (8:38 a.m.) September 11, 2001). Rountree asks, “Is that real-world?” Dooley confirms, “Real-world hijack.” Watson says, “Cool!” [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 25] When NEADS Commander Robert Marr sees his personnel reacting to the news of the hijacking (see (8:38 a.m.) September 11, 2001), he reportedly thinks the day’s exercise “is kicking off with a lively, unexpected twist.” Even when a colleague informs him, “It’s a hijacking, and this is real life, not part of the exercise,” Marr thinks: “This is an interesting start to the exercise. This ‘real-world’ mixed in with today’s simex [simulated exercise] will keep [my staff members] on their toes.” [Spencer, 2008, pp. 26] Major General Larry Arnold, who is at Tyndall Air Force Base, Florida, also later says that when he first hears of the hijacking, in the minutes after NEADS is alerted to it, “The first thing that went through my mind was, is this part of the exercise? Is this some kind of a screw-up?” [ABC News, 9/11/2002; 9/11 Commission, 5/23/2003] According to author Lynn Spencer: “Even as NORAD’s commander for the continental United States, Arnold is not privy to everything concerning the exercise. The simex is meant to test commanders also, to make sure that their war machine is operating as it should.” [Spencer, 2008, pp. 38] At 8:43 a.m., Major James Fox, the leader of the NEADS weapons team, comments, “I’ve never seen so much real-world stuff happen during an exercise.” [Vanity Fair, 8/1/2006]
8:38 a.m. September 11, 2001: NEADS Commander Tries Calling Superior for Permission to Launch Fighters, but Has to Leave Message
Colonel Robert Marr, the battle commander at NORAD’s Northeast Air Defense Sector (NEADS), tries phoning Major General Larry Arnold, the commander of the Continental United States NORAD Region (CONR), to get authorization to scramble fighter jets in response to the hijacked Flight 11, but Arnold is in a teleconference, so Marr has to leave an urgent message requesting that Arnold call him back. [9/11 Commission, 7/24/2004, pp. 20; Spencer, 2008, pp. 31]
Arnold Unavailable to Authorize Launching Fighters – Marr has just learned that the FAA is requesting NORAD assistance with a possible hijacking (see (8:38 a.m.) September 11, 2001), and has therefore ordered that fighter jets at Otis Air National Guard Base, Massachusetts, be placed on “battle stations,” with the pilots in the cockpits but the engines turned off (see (8:40 a.m.) September 11, 2001). [Filson, 2003, pp. 55; 9/11 Commission, 7/24/2004, pp. 20] He now tries calling Arnold at CONR headquarters, at Tyndall Air Force Base, Florida, to get authorization to scramble the fighters. However, Arnold is in a teleconference with other senior NORAD officials (see (8:30 a.m.-8:40 a.m.) September 11, 2001) and is therefore unavailable to talk to Marr. [Spencer, 2008, pp. 31]
Marr Leaves Urgent Message for Arnold – Marr talks to Colonel Randy Morris, the assistant director of the CONR Regional Air Operations Center, and tells him about the possible hijacking. Morris replies that such an event “falls under law enforcement jurisdiction.” Marr says the FAA has requested military assistance with the hijacking and NEADS is “forward leaning” fighters from Otis Air Base, referring to his order to place Otis fighters on battle stations. [9/11 Commission, 2/3/2004 ] Marr leaves an urgent message for Arnold, stating that he is dealing with a hijacking and requesting that Arnold call him back. [9/11 Commission, 5/23/2003; Spencer, 2008, pp. 31] Arnold will be given Marr’s message after he leaves the teleconference (see (8:40 a.m.) September 11, 2001) and will promptly call Marr back (see (8:42 a.m.) September 11, 2001). [Filson, 2002; 9/11 Commission, 5/23/2003; 9/11 Commission, 2/3/2004 ] It is unclear why no one interrupts the teleconference to fetch Arnold to come and talk with Marr right away, or at least to immediately pass on Marr’s message.
Unclear if Marr Needs Authorization to Scramble Fighters – It is also unclear why Marr seeks authorization from his superior before ordering that fighters be scrambled. According to Lieutenant Colonel Dawne Deskins, the aircraft control and warning officer at NEADS, the mission crew commander at NEADS—i.e. Major Kevin Nasypany—“is the lowest level rank that has the authority to give a scramble order.” However, Deskins will tell the 9/11 Commission: “[S]ince Colonel Marr was in the battle cab, it was his role. Since the decision involved a civilian aircraft, he had to be the one who made the decision.” [9/11 Commission, 10/30/2003 ] The 1st Air Force’s book about the 9/11 attacks will similarly state that the “sector commander” at NEADS, i.e. Marr, “would have authority to scramble the airplanes.” [Filson, 2003, pp. 50] But Arnold will say the reason the Otis fighters are placed on battle stations instead of being scrambled immediately is that aircraft hijacking is “considered a law enforcement issue.” The correct procedure, according to Arnold, is therefore that, if the FAA wants fighters scrambled, it should call the duty officer at the National Military Command Center at the Pentagon. He in turn contacts the NORAD operations center in Cheyenne Mountain, Colorado, to see if fighters are available. The operations center then seeks permission from someone representing the secretary of defense. Finally, “Once that is approved, then we scramble aircraft,” Arnold will say (see June 1, 2001). [Filson, 2002; Code One Magazine, 1/2002; 9/11 Commission, 5/23/2003]
8:40 a.m. September 11, 2001: CONR Commander Arnold Learns of Hijacking upon Leaving Teleconference, Thinks It Is Part of Exercise
Major General Larry Arnold, the commander of the Continental United States NORAD Region (CONR), learns of the possible hijacking of Flight 11 after leaving a video teleconference, but initially thinks the reported hijacking is part of a NORAD training exercise. [Filson, 2002; Code One Magazine, 1/2002] Arnold, who is at CONR headquarters, at Tyndall Air Force Base, Florida, has been in the video teleconferencing room, participating in a teleconference with other senior NORAD officials (see (8:30 a.m.-8:40 a.m.) September 11, 2001). [9/11 Commission, 2/2/2004 ; Spencer, 2008, pp. 31] Colonel Robert Marr, the battle commander at NORAD’s Northeast Air Defense Sector (NEADS), recently tried phoning Arnold to get authorization to scramble fighter jets in response to the hijacked Flight 11, but no one at CONR interrupted the teleconference to fetch Arnold, and so Marr left an urgent message for the CONR commander (see (8:38 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20; Spencer, 2008, pp. 31]
Note Informs Arnold of Hijacking – Arnold is now in the video teleconferencing room with Robert Del Toro, an intelligence officer with the 1st Air Force, discussing the just-concluded teleconference, when his executive officer, Kelley Duckett, hands him a note with Marr’s message on it. The note says the FAA’s Boston Center is reporting a hijacking and requesting assistance with it, and asks that Arnold phone Marr back immediately. [Filson, 2002; 9/11 Commission, 5/23/2003; 9/11 Commission, 2/2/2004 ; 9/11 Commission, 2/3/2004 ]
Arnold Thinks Hijacking Is ‘Part of the Exercise’ – NORAD is currently in the middle of a major training exercise called Vigilant Guardian. [Code One Magazine, 1/2002; Arkin, 2005, pp. 545] Arnold will later say that, as a result, when he learns of the possible hijacking: “The first thing that went through my mind was: ‘Is this part of the exercise? Is this some kind of a screw-up?’” [ABC News, 9/11/2002] According to author Lynn Spencer, “Even as NORAD’s commander for the continental United States, Arnold is not privy to everything concerning the exercise.” The exercise “is meant to test commanders also, to make sure that their war machine is operating as it should.”
Arnold Told Hijacking Is ‘Real-World’ – Since a simulated hijacking is scheduled as part of the day’s exercise (see (9:40 a.m.) September 11, 2001), Arnold asks Duckett, “Is this part of the exercise?” Duckett replies that the hijacking is real-world. [Spencer, 2008, pp. 38] Arnold will say that “understanding this is real-world is obviously important, so I rushed downstairs to our battle staff position.” [Filson, 2002] It occurs to Arnold that it has been many years since NORAD handled a hijacking (see February 11, 1993). He is relieved that, “because we were in the middle of an exercise,” he recently reviewed the protocol for what to do in response to a hijacking, and so “we were pretty well familiar with those procedures.” [9/11 Commission, 5/23/2003; Spencer, 2008, pp. 38] Arnold will promptly phone Marr and instruct him to go ahead and scramble fighters in response to the hijacking (see (8:42 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20; Spencer, 2008, pp. 38-39]
8:42 a.m. September 11, 2001: CONR Commander Arnold Tells NEADS Commander Marr to Scramble Fighters
Major General Larry Arnold, the commander of the Continental United States NORAD Region (CONR), calls Colonel Robert Marr, the battle commander at NORAD’s Northeast Air Defense Sector (NEADS), who is seeking authorization to scramble fighter jets in response to the hijacked Flight 11, and instructs him to “go ahead and scramble them, and we’ll get authorities later.” [9/11 Commission, 7/24/2004, pp. 20; Spencer, 2008, pp. 38-39] After learning that the FAA wants NORAD assistance with a possible hijacking (see (8:38 a.m.) September 11, 2001), Marr tried calling Arnold at CONR headquarters, at Tyndall Air Force Base, Florida, for permission to scramble fighters from Otis Air National Guard Base in Massachusetts (see (8:38 a.m.) September 11, 2001). Arnold was in a teleconference (see (8:30 a.m.-8:40 a.m.) September 11, 2001), so Marr left a message requesting that Arnold call him back. [Aviation Week and Space Technology, 6/3/2002; Filson, 2003, pp. 55-56; Spencer, 2008, pp. 31] With the teleconference now over, Arnold calls Marr on a secure phone line and is informed of the ongoing situation. [9/11 Commission, 5/23/2003; 9/11 Commission, 2/3/2004 ]
Marr Reports Hijacking, Wants to Scramble Fighters – Marr says the FAA’s Boston Center is “reporting a possible hijacked aircraft, real-world, somewhere north of JFK Airport.” He says, “I’ve got Otis [fighters] going battle stations [i.e. with the pilots in the cockpits but the engines turned off] and I’d like to scramble them to military airspace while we try to get approval for an intercept.” Arnold had wondered if the reported hijacking was a simulation, as part of a NORAD training exercise taking place on this day (see (8:40 a.m.) September 11, 2001), and therefore asks, “Confirm this is real-world?” Marr confirms that the hijacking is “real-world.”
Marr Lacks Details of Hijacked Flight – Arnold asks where the hijacked aircraft is and Marr replies: “We don’t have a good location. The FAA says they don’t have it on their scopes, but had it west of Boston and thought it was now heading to New York.” Arnold then asks, “Do we have any other information, type, tail, number of souls on board?” to which Marr replies, “I don’t have all the particulars yet, but we’ll pass them on as we get them.”
Arnold Tells Marr to Scramble Fighters – According to author Lynn Spencer, in response to Marr’s request to scramble the Otis fighters, “Arnold’s instincts tell him to act first and seek authorizations later.” [Spencer, 2008, pp. 38-39] He therefore says, “Go ahead and scramble them, and we’ll get authorities later.” [Filson, 2003, pp. 56; 9/11 Commission, 7/24/2004, pp. 20] Marr tells Arnold he will “scramble Otis to military airspace” while they try to figure out what is going on. [Grant, 2004, pp. 20] Arnold will later recall that it is his and Marr’s intention to place the fighters in “Whiskey 105”—military airspace over the Atlantic Ocean, just south of Long Island—“since neither he nor Marr knew where the hijacked aircraft was.” [9/11 Commission, 2/3/2004 ] Arnold ends by saying, “Let me know when the jets get airborne,” and adds that he will “run this up the chain” of command. Marr will then direct the NEADS mission crew commander to issue the scramble order (see 8:45 a.m. September 11, 2001). Meanwhile, Arnold will call the NORAD operations center in Cheyenne Mountain, Colorado, about the hijacking, and officers there tell him they will contact the Pentagon to get the necessary clearances for the scramble (see (8.46 a.m.) September 11, 2001). [Filson, 2003, pp. 56; Spencer, 2008, pp. 39]
8:45 a.m. September 11, 2001: NEADS Commanders Give Order to Launch Otis Jets
On the operations floor at NORAD’s Northeast Air Defense Sector (NEADS), Major Kevin Nasypany, the facility’s mission crew commander, instructs Major James Fox, the leader of the weapons team, to launch fighter jets from Otis Air National Guard Base in Cape Cod, Massachusetts. [Vanity Fair, 8/1/2006] Nasypany has just received this order—to launch the jets—from Colonel Robert Marr, the NEADS battle commander. [9/11 Commission, 8/26/2004, pp. 15 and 88] Marr issued it after seeking permission to do so from Major General Larry Arnold, the commanding general of NORAD’s Continental Region (CONR) (see (8:42 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] Marr will later claim, “My intent was to scramble Otis to military airspace while we found out what was going on.” [Filson, 2003, pp. 56] Nasypany gives Fox a coordinate for just north of New York City, and tells him, “Head ‘em in that direction.” [Vanity Fair, 8/1/2006] The jets will be scrambled from Otis a minute later (see 8:46 a.m. September 11, 2001), but there will be conflicting accounts of what their initial destination is (see (8:53 a.m.-9:05 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] Interestingly, the 9/11 Commission will later state that, “Because of a technical issue, there are no NEADS recordings available of the NEADS senior weapons director and weapons director technician position responsible for controlling the Otis scramble.” [9/11 Commission, 7/24/2004, pp. 459]
8.46 a.m. September 11, 2001: NORAD Operations Center Director Agrees to Scrambling of Fighters in Response to Hijacking
The NORAD operations center in Cheyenne Mountain, Colorado, receives a call notifying it that the FAA has requested military assistance with a hijacking, and senior officers there agree with the decision that has been made to launch fighter jets in response to the hijacking, and say they will call the Pentagon to get the necessary clearance for this. [Filson, 2003, pp. 56; 9/11 Commission, 3/1/2004 ; Spencer, 2008, pp. 39] Major General Larry Arnold, the commander of the Continental United States NORAD Region, has just talked over the phone with Colonel Robert Marr at NORAD’s Northeast Air Defense Sector (NEADS), and Marr suggested to him that fighters be scrambled in response to the hijacked Flight 11. Arnold told Marr to go ahead with the scramble and said he would sort out getting authorization for it (see (8:42 a.m.) September 11, 2001). Arnold therefore now calls the Cheyenne Mountain Operations Center (CMOC). The call is answered by Captain Michael Jellinek, the command director on duty there. [Aviation Week and Space Technology, 6/3/2002; Spencer, 2008, pp. 38-39] Arnold says the FAA has requested assistance for an ongoing hijacking. [9/11 Commission, 3/1/2004 ]
NORAD Director Approves Decision to Launch Fighters – Jellinek passes on the details of the request to Major General Rick Findley, NORAD’s director of operations, who has just finished the night shift and is returning to the CMOC battle cab from breakfast. Jellinek will later recall: “I pick up the other phone because I know [Findley is] there. One button and I’m talking to him. It’s faster to do that than walk around the window, say the same thing.” [Calgary Herald, 10/1/2001; Canadian Broadcasting Corporation, 11/27/2001; Toronto Star, 12/9/2001] Findley “concurs with Arnold’s assessment and decision to scramble the fighters,” according to author Lynn Spencer, and quickly approves the fighters’ launch. [Aviation Week and Space Technology, 6/3/2002; Spencer, 2008, pp. 39] He “immediately gives the thumbs up” through the window, according to Jellinek. [Canadian Broadcasting Corporation, 11/27/2001] Arnold will say he is told (presumably by Jellinek): “Yeah, we’ll work this with the National Military Command Center [at the Pentagon]. Go ahead and scramble the aircraft.” [Filson, 2002; Filson, 2003, pp. 56] According to Findley: “At that point, all we thought was we’ve got an airplane hijacked and we were going to provide an escort as requested [by the FAA]. We certainly didn’t know it was going to play out as it did.” [Ottawa Citizen, 9/11/2002]
NORAD Personnel Request Permission for Scramble – Findley will say that after the CMOC receives the call from Arnold, he “knew what to do, and so did everybody else on the battle staff.” He tells the members of the battle staff to “open up our checklist” and “follow our NORAD instruction,” which includes having “to ask in either Ottawa or Washington, ‘Is it okay if we use NORAD fighters to escort a potential hijacked aircraft?’” [CNN, 9/11/2006] Findley and the others in the CMOC will subsequently see the coverage on CNN, reporting that a plane has hit the World Trade Center, but do not initially realize the plane involved was the hijacked aircraft they have been called about (see (8:48 a.m.) September 11, 2001). [Calgary Herald, 10/1/2001; Ottawa Citizen, 9/11/2002; Defense Video and Imagery Distribution System, 9/8/2011]
8:53 a.m.-9:05 a.m. September 11, 2001: Otis Fighters Head toward New York Area; Accounts Conflict over Exact Destination
The two F-15 fighter jets launched from Otis Air National Guard Base in Cape Cod respond to the hijacking of Flight 11, but there will be conflicting accounts regarding their initial destination. The fighters were scrambled at 8:46 (see 8:46 a.m. September 11, 2001), and are airborne by 8:53 (see 8:53 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20]
Flying toward New York City – News reports shortly after 9/11 will say that, after taking off, the Otis fighters begin “racing towards New York City.” [CBS News, 9/14/2001; CNN, 9/14/2001; Cape Cod Times, 9/15/2001] Other news reports similarly say they initially head toward New York City. [Washington Post, 9/12/2001; Aviation Week and Space Technology, 6/3/2002; Fox News, 9/8/2002] Major General Larry Arnold, the commanding general of NORAD’s Continental Region, will say the fighters are “coming to New York.” [MSNBC, 9/23/2001; Slate, 1/16/2002] Lieutenant Colonel Timothy Duffy, the lead Otis pilot, tells the BBC, “When we took off we started climbing a 280-heading, basically towards New York City.” [BBC, 9/1/2002] In one account, Duffy recalls that, after launching, he calls for the location of his target and is told, “Your contact’s over Kennedy,” meaning New York’s JFK International Airport. Duffy will add, “[W]e started heading right down to Long Island, basically.” [ABC News, 9/11/2002; Bamford, 2004, pp. 15] In another account, he says that he and the other Otis pilot, Major Daniel Nash, “climbed up, [and] we were supersonic going down to Long Island.” [Filson, 2003, pp. 57]
Without a Target, Heading for Military Airspace – According to some accounts, however, the two Otis fighters do not initially head toward Manhattan. Major James Fox, the leader of the weapons team at NORAD’s Northeast Air Defense Sector (NEADS), will later recall: “We had no idea where [Flight 11] was. We just knew it was over land, so we scrambled [the Otis fighters] towards land.” [Newhouse News Service, 1/25/2002] The 9/11 Commission will conclude that, after taking off, because they are “Lacking a target,” the fighters are “vectored toward military-controlled airspace off the Long Island coast.” [9/11 Commission, 7/24/2004, pp. 20] Colonel Robert Marr, the battle commander at NEADS, says that when the Otis fighters took off, his “intent was to scramble [them] to military airspace while we found out what was going on.” He says that, before 9:03 a.m. when the second World Trade Center tower is hit, the fighters are “heading down south toward Whiskey 105 and we don’t really have a mission for them at this point.” Whiskey 105 is military training airspace southeast of Long Island, a few minutes flying time from New York City. [Filson, 2003, pp. 56 and 58-59]
To New York, Then Redirected to Military Airspace – Other accounts will say the Otis fighters initially head toward New York City, but are subsequently redirected to the military airspace off Long Island (see 8:54 a.m.-8:55 a.m. September 11, 2001). According to author Lynn Spencer, after taking off, Duffy and Nash fly “supersonic toward New York for approximately 15 minutes.” But just after the second WTC tower is hit, Duffy suggests to the weapons controller at NEADS that the two fighters head to the Whiskey 105 training airspace off Long Island, and that is where they then go. [Spencer, 2008, pp. 83-85] Tape recordings of the NEADS operations floor will reveal that, at 8:45 a.m., Major Kevin Nasypany, the facility’s mission crew commander, gave Major Fox a coordinate north of New York City, and told him to “Head [the Otis jets] in that direction” (see 8:45 a.m. September 11, 2001). Then, at 8:52, he told one of his staff members, “Send ‘em to New York City still” (see 8:53 a.m. September 11, 2001). But, according to Vanity Fair, shortly after the second tower is hit, the NEADS weapons technicians get “pushback” from civilian FAA controllers, who are “afraid of fast-moving fighters colliding with a passenger plane,” so the two fighters are directed to a “holding area” just off the coast, near Long Island (see 9:09 a.m.-9:13 a.m. September 11, 2001). [Vanity Fair, 8/1/2006] Accounts are also unclear regarding what speed the Otis jets fly at after taking off (see (8:53 a.m.-9:05 a.m.) September 11, 2001).
8:53 a.m.-9:05 a.m. September 11, 2001: Otis Fighters Fly toward New York Area; Accounts Unclear over Speed
The two F-15 fighter jets that took off from Otis Air National Guard Base in Cape Cod head toward the New York area. But accounts will be unclear regarding what speed they fly at as they respond to the hijacking of Flight 11. The two jets were scrambled from Otis at 8:46 (see 8:46 a.m. September 11, 2001), and are airborne by 8:53 (see 8:53 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20]
Flying Supersonic – In a number of accounts, it is claimed the fighters fly faster than the speed of sound. [Cape Cod Times, 8/21/2002] Lead pilot Lt. Col. Timothy Duffy will tell the BBC: “I was supersonic.… I don’t know what we could have done to get there any quicker.” [BBC, 9/1/2002] He tells ABC News, “[W]e go supersonic on the way, which is kind of nonstandard for us.” [ABC News, 9/11/2002] According to author Lynn Spencer, “against regulations, [Duffy] takes his plane supersonic, breaking the sound barrier as he passes through 18,000 feet. This is a violation that can get a pilot into a good deal of trouble since the sonic boom tends to break windows in the homes down below.” When the other Otis pilot, Major Daniel Nash, radios and says, “You’re supersonic,” Duffy responds, “Yeah, I know, don’t worry about it.” Then, “Without hesitation, [Nash] follows his lead” and also goes supersonic.

Flying ‘Full Blower’ – Duffy will recall, “I was in full blower all the way,” as he flies toward New York. [Aviation Week and Space Technology, 6/3/2002] In another account, he similarly says, “When we took off I left it in full afterburner the whole time.” [Filson, 2003, pp. 57] F-15s can fly at up to 1,875 miles per hour. [Cape Cod Times, 9/12/2001; US Air Force, 3/2008] According to an Otis Air Base spokeswoman, “An F-15 departing from Otis can reach New York City in 10 to 12 minutes.” [Cape Cod Times, 9/16/2001] But, according to the Boston Globe, while “In their prime, the planes can go Mach 2.5 [and] could have been to New York in less than 10 minutes,” Duffy and Nash are “flying F-15 Eagles that were built in 1977.… Because of their age and the three large fuel tanks they were carrying… the planes couldn’t attain that speed, both pilots said.” [Boston Globe, 9/11/2005]
Different Speeds Given – Various speeds will later be given for how fast the Otis jets are traveling. Consistent with Duffy’s claims of flying “supersonic,” ABC News says the two fighters fly “at Mach 1.2, nearly 900 miles per hour.” [ABC News, 9/11/2002] According to the Boston Globe, the fighters are flying at “about Mach 1.4—more than 1,000 miles per hour.” [Boston Globe, 9/11/2005] Major General Larry Arnold, the commanding general of NORAD’s Continental Region, says they fly at “about 1.5 Mach, which is, you know, somewhere—11 or 1,200 miles an hour.” [MSNBC, 9/23/2001; Slate, 1/16/2002] Major General Paul Weaver, the director of the Air National Guard, says the jets fly “like a scalded ape,” but as to their exact speed, he only says they are “topping 500 mph.” [Dallas Morning News, 9/16/2001] And by 9:03 a.m., when the second World Trade Center tower is hit, the Otis fighters are still 71 miles from New York, according to NORAD. [North American Aerospace Defense Command, 9/18/2001] The 9/11 Commission will state that they only arrive over Manhattan at 9:25 a.m. (see 9:25 a.m. September 11, 2001), though accounts of most witnesses on the ground indicate they do not arrive until after 10:00 a.m. (see (9:45 a.m.-10:45 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 24] Accounts are contradictory regarding what exact destination the Otis jets are initially heading toward after taking off (see (8:53 a.m.-9:05 a.m.) September 11, 2001).
Shortly After 9:03 a.m. September 11, 2001: NORAD Training Exercise Canceled
A NORAD training exercise that is taking place this morning, presumably Vigilant Guardian (see (6:30 a.m.) September 11, 2001), is reportedly canceled shortly after 9:03, when the second World Trade Center tower is hit. [Airman, 3/2002] NORAD Commander Larry Arnold later says that after Flight 175 hits the South Tower, “I thought it might be prudent to pull out of the exercise, which we did.” [Filson, 2003, pp. 59] According to author Lynn Spencer: “The phone calls start flying between the various NORAD command centers. General Arnold calls Maj. Gen. Rick Findley” at NORAD’s operations center in Cheyenne Mountain, Colorado, “to give him the latest information and have him withdraw all forces from the simulated exercise.” [Spencer, 2008, pp. 86] Arnold will recall, “As we pulled out of the exercise we were getting calls about United Flight 93 and we were worried about that.” [Filson, 2003, pp. 59] Some early accounts say the military receives notification of the possible hijacking of Flight 93 at around 9:16 a.m. (see 9:16 a.m. September 11, 2001). [CNN, 9/17/2001; 9/11 Commission, 5/23/2003] However, the 9/11 Commission will later claim that NORAD’s Northeast Air Defense Sector (NEADS) first receives a call about Flight 93 at 10:07 a.m. (see 10:05 a.m.-10:08 a.m. September 11, 2001). [9/11 Commission, 6/17/2004 ] Arnold will add, “Then we had another call from Boston Center about a possible hijacking, but that turned out to be the airplane that had already hit the South Tower but we didn’t know that at the time.” [Filson, 2003, pp. 59]
