One of the ID technicians at NORAD's Northeast Air Defense Sector (NEADS) calls the FAA's Boston Center, and learns that there have been "threats in the cockpit" of Flight 11. The communications team at NEADS is currently trying to quickly find out all they can about the hijacked plane, such as its flight number, tail number, and where it is. ID tech Shelley Watson calls the management desk at the Boston Center, which had alerted NEADS to the hijacking minutes earlier (see (8:37 a.m.) September 11, 2001), wanting to make sure she has all the information that is available on Flight 11. Her call is answered by Boston Center's military liaison, Colin Scoggins. Scoggins tells Watson: "He's being hijacked. The pilot's having a hard time talking to the... I mean, we don't know. We don't know where he's goin'. He's heading towards Kennedy [International Airport in New York City]. He's... 35 miles north of Kennedy now at 367 knots. We have no idea where he's goin' or what his intentions are." Scoggins says, "I guess there's been some threats in the cockpit," and adds, "We'll call you right back as soon as we know more info." Master Sergeant Maureen Dooley is standing over Watson, relaying any pertinent information she hears to Major Kevin Nasypany. She calls to him, "Okay, he said threat to the cockpit!"

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 pdf file; 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 pdf file; 9/11 Commission, 2/3/2004 pdf file]

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]

At the FAA's Herndon Command Center, the national operations manager, Ben Sliney, learns more details of the hijacking of Flight 11, and becomes involved with the emergency response to it. [Spencer, 2008, pp. 21]

A supervisor at the Command Center informed Sliney of the suspected hijacking at just before 8:30 (see 8:28 a.m. September 11, 2001). Soon after, the supervisor interrupted a meeting Sliney was in, to tell him American Airlines had called to report the deteriorating situation on Flight 11 (see 8:30 a.m.-8:40 a.m. September 11, 2001).

Sliney Receives More Details - Sliney heads to the center's operations floor, where the supervisor gives him further details of the call from American Airlines, including information about flight attendant Betty Ong's phone call from Flight 11 (see 8:19 a.m. September 11, 2001). The supervisor says the plane's transponder has been switched off (see (Between 8:13 a.m. and 8:21 a.m.) September 11, 2001), which means no flight data is showing on the screens of air traffic controllers, and the latest information from the FAA's Boston Center is that Flight 11 has turned south, and is now 35 miles north of New York City. On one of the large screens at the front of the Command Center that shows flight trajectories, Sliney can see that the track for Flight 11 is in "ghost." This means that, because no transponder data is being received, the computer is displaying track information based on previously stored track data.

Sliney Seeks Information, Requests Teleconference - Sliney instructs his staff to contact facilities along the path the flight appears to be on, to find if anyone is in contact with it or tracking it. [Spencer, 2008, pp. 1 and 19-21] He will later recall, "I figured we'd try to get the people on the ground, the towers in the area, the police departments, anyone we could get to give us information on where this flight was." [Canadian Broadcasting Corporation, 9/10/2006]

Sliney then requests a teleconference between the FAA's Boston Center, New York Center, and FAA headquarters in Washington, so they can share information about the flight in real time. [Spencer, 2008, pp. 21]

The Command Center has already initiated a teleconference between the Boston, New York, and Cleveland Centers, immediately after it was notified of the suspected Flight 11 hijacking. [9/11 Commission, 8/26/2004, pp. 11]

However, Sliney apparently does not request military assistance. According to author Lynn Spencer, "The higher echelons at headquarters in Washington will make the determination as to the necessity of military assistance in dealing with the hijacking." [Spencer, 2008, pp. 21]

Nancy Wyatt, a manager at the American Airlines flight services office at Logan International Airport in Boston, talks on the phone with an employee at the American Airlines System Operations Control (SOC) center, and passes on to them information that is being provided by a flight attendant on the hijacked Flight 11, but the SOC employee advises Wyatt to keep quiet about the hijacking. [American Airlines, 9/11/2001, pp. 34-41; 9/11 Commission, 2004, pp. 4; 9/11 Commission, 8/26/2004, pp. 14; Rutgers Law Review, 9/7/2011, pp. 14 pdf file]

Amy Sweeney, a flight attendant on Flight 11, called the flight services office at 8:32 a.m., and has since then been providing details of the trouble on her plane to Michael Woodward, an American Airlines flight services manager at Logan Airport (see (8:32 a.m.-8:44 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 11]

Wyatt Passes on Details of Call in Real Time - Wyatt, who, like Woodward, is an American Airlines flight services manager, calls the American Airlines SOC in Fort Worth, Texas, at 8:40 a.m. Her call is answered by Ray Howland. [Federal Bureau of Investigation, 9/15/2001, pp. 2-4; 9/11 Commission, 2004, pp. 4; 9/11 Commission, 8/26/2004, pp. 14]

During the call, Wyatt is able to pass on information to Howland in real time, because she is standing next to Woodward and so is hearing his side of the conversation with Sweeney, and she is also able to read the notes he is taking, based on what Sweeney tells him. [9/11 Commission, 1/25/2004 pdf file]

Wyatt Unclear about Name of Flight Attendant - Wyatt is unclear about the identity of the flight attendant Woodward is talking to. At the start of the call with Howland, she says, "We've got the flight attendants on the line here." A couple of minutes later, she says, "We've got... Betty Ong, the purser, on the line." [American Airlines, 9/11/2001, pp. 34-41]

However, Ong is currently on the phone with the American Airlines Southeastern Reservations Office in North Carolina (see 8:18 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 8]

Finally, another couple of minutes later and after checking with Woodward, Wyatt tells Howland, "Amy Sweeney is on the phone."

Wyatt Passes on Hijackers' Seat Numbers - Based on Sweeney's information, Wyatt says that Flight 11 "is in a rapid descent." She tells Howland that the hijackers were in seats 9D, 9G, and 10B, and she says one of them "speaks no English." She also reports, several minutes into the call, that the hijackers are "in the cockpit." Wyatt tells Howland that two flight attendants, Karen Martin and Barbara Arestegui, have been stabbed. [American Airlines, 9/11/2001, pp. 34-41]

Referring to passenger Daniel Lewin, who was attacked by one of the hijackers (see (8:20 a.m.) September 11, 2001), she says: "There is severe bleeding. There is a slashed throat." She subsequently says, "There is a passenger also injured." [American Airlines, 9/11/2001, pp. 34-41; WBUR, 9/8/2011]

Airline Wants Information Withheld from Plane's Crew - During the call, Howland tells Wyatt that the SOC wants some information to be withheld from Sweeney and the other crew members on Flight 11. After Wyatt says the flight attendants on Flight 11 "are concerned" because they "don't know what's going on in the cockpit," Howland replies that the SOC is "trying to get in contact with the cockpit," but then says, "We don't really want to tell Sweeney that." Wyatt confirms: "Okay, don't. Okay, okay. Got it." And when Wyatt later asks: "Do we know where that plane is going to right now?" Howland replies: "We don't know.... It looks like it's going to JFK" International Airport in New York, but he then says: "I mean, we don't really want to give a whole lot of information to that flight. Okay?" Wyatt confirms: "Okay, we're not. We're not giving them that information to that flight."

Airline Employees Told to Keep Quiet about Hijacking - Wyatt and Howland also want American Airlines employees on the ground to keep quiet about the hijacking. At about 8:46 a.m., while she is still on the phone with Howland, Wyatt says to a colleague of hers: "Evelyn, don't mention this to anyone. Me, you, Beth. Just the five of us. Okay?" [American Airlines, 9/11/2001, pp. 34-41]

("Evelyn" and "Beth" are Evelyn Nunez and Elizabeth Williams, two American Airlines employees at Logan Airport. [Federal Bureau of Investigation, 9/11/2001, pp. 57-58; Federal Bureau of Investigation, 9/13/2001, pp. 3-4; 9/11 Commission, 1/25/2004 pdf file] )

Near the end of her call with Howland, Wyatt asks, "What do you want us to do as far as just keeping our mouths shut and not... ?" Howland answers simply, "That's basically it." [American Airlines, 9/11/2001, pp. 34-41] Wyatt notifies Howland when the call from Sweeney gets disconnected, at around 8:45 a.m. (see (8:44 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 14] Her call with Howland ends at 8:48 a.m. [9/11 Commission, 2004, pp. 4]

Craig Marquis, the manager on duty at the American Airlines System Operations Control (SOC) center in Fort Worth, Texas, instructs Bill Halleck, an air traffic control specialist at the SOC, to tell FAA air traffic controllers to treat Flight 11 as an emergency. [American Airlines, 9/11/2001, pp. 7-19; 9/11 Commission, 11/19/2003 pdf file; 9/11 Commission, 8/26/2004, pp. 14]

Halleck contacted the FAA's Boston Center at 8:29 a.m. to inquire about Flight 11 (see 8:29 a.m. September 11, 2001), and at 8:33 a.m. he called Marquis and passed on what he had just learned from the Boston Center about the crisis with the aircraft (see 8:33 a.m. September 11, 2001). That information, according to the 9/11 Commission, led American Airlines to suspect that Flight 11 had been hijacked. [9/11 Commission, 8/26/2004, pp. 11-12]

Marquis now instructs Halleck, "Tell [air traffic control] to handle this as an emergency." According to a 9/11 Commission memorandum, "At this point, Marquis was just confirming it was a hijack and he wanted to make sure Halleck was communicating the emergency to the [air traffic control] system." Halleck answers that FAA controllers are treating Flight 11 as a hijacking, saying, "They have in there, it's been hijacked." Marquis replies: "It is. Okay." Halleck adds that FAA controllers "don't know what his altitude is... they think he's descending. They think he's headed toward Kennedy [JFK International Airport in New York]... they're moving everybody out of the way." Referring to Betty Ong, a flight attendant on Flight 11, Marquis tells Halleck, "I'm talking to the flight attendant in the back of the plane and she says the plane is descending." [American Airlines, 9/11/2001, pp. 7-19; American Airlines, 1/15/2002; 9/11 Commission, 11/19/2003 pdf file]

Colin Scoggins, the military liaison at the FAA's Boston Center, calls the FAA's New York Center but is quickly cut off when the air traffic controller who answers says the center is busy dealing with a hijacking. According to author Lynn Spencer, Scoggins "calls New York Center to notify them that American 11 appears to be descending toward New York, most likely to land at JFK" International Airport. But the controller who takes the call snaps at him: "We're too busy to talk. We're working a hijack," and then hangs up. According to Spencer, the New York Center controller is referring to United Airlines Flight 175, but "Scoggins just figures that he's talking about American 11. He has no idea that a second airliner is in crisis." However, the timing of this call is unclear. If it is made while Flight 11 is descending toward New York, this would mean it occurs in the minutes before 8:46, when American Airlines Flight 11 crashes (see 8:46 a.m. September 11, 2001). But in Spencer's account, the call is made just after New York Center controller Dave Bottiglia notices that Flight 175's transponder code has changed and he calls out to another controller, "I can't get a hold of UAL 175 at all right now and I don't know where he went to" (see 8:51 a.m.-8:53 a.m. September 11, 2001). [Spencer, 2008, pp. 48-49] The transcript of radio communications between the New York Center and Flight 175 shows that this would mean Scoggins's call occurs around 8:53 a.m.-8:54 a.m., about seven minutes after Flight 11 crashes. [New York Times, 10/16/2001]

While flying south along the Hudson River, Flight 11 passes almost directly over the Indian Point nuclear power plant in Buchanan, NY, about 30 miles north of New York City. [New York Times, 4/4/2002; Bergen Record, 4/7/2002]

The New Yorker will later comment, "An attack on a nuclear power plant would seem to fulfill, almost perfectly, al-Qaeda's objective of using America's technology against it," and the New York Times will report, "Everyone within at least a 50-mile radius would be in danger if something terrible happened at Indian Point. That 50-mile radius contains more than 7 percent of the entire population of the United States—20 million people." [New York Times, 4/4/2002; New Yorker, 2/24/2003]

Mohamed Atta supposedly earlier considered targeting a nuclear facility on 9/11, but the other suicide pilots did not like the idea (see Between July 9 and July 16, 2001).

Technicians at NORAD's Northeast Air Defense Sector (NEADS) try frantically to locate Flight 11 on their radar scopes, but are supposedly hindered by their outdated equipment. [Spencer, 2008, pp. 31-32]

NEADS has just been alerted to the hijacking of Flight 11 (see (8:37 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20]

Its technicians realize they need to find the location of the hijacked plane quickly, so that the weapons team will be able to pass this information on to any fighter jets that are launched after it.

Locating Flight 11 Is a 'Grueling Process' - Author Lynn Spencer will later explain: "To identify American 11, the surveillance and ID techs must go through a grueling process. Their radar scopes are filled with hundreds of radar returns not just from aircraft but from weather systems, ground interference, and what's called anomalous propagation—false returns caused by conditions in the atmosphere, or by such obstructions as flocks of birds. The technicians must first determine which radar data on their screens is for aircraft, which they do by monitoring its movement, which is distinctive for planes. The technician must observe for at least 36 seconds to a minute just to confirm that a blip is in fact an aircraft track. The tech must attach what's called a tactical display number to it, which tells the computer to start tracking and identifying the target. If the target is in fact a plane, then over a period of 12-20 seconds, the computer will start to generate information on the track: heading, speed, altitude, latitude, longitude, and the identifying information being transmitted by the transponder." However, Flight 11's transponder has been switched off (see (Between 8:13 a.m. and 8:21 a.m.) September 11, 2001). Therefore, "With the hundreds of pieces of radar data filling their screens, and little information as to the location of the flight," the task of locating it "is daunting."

Radar Equipment Supposedly Unsuitable - Spencer will suggest that trying to locate Flight 11 is made more difficult because the radar equipment at NEADS is outdated and unsuited to the task at hand. She writes: "The NEADS radar equipment is different from that used by air traffic controllers. It's much older, developed in the 1970s and brought into use by NEADS in the early 1980s. The system was designed to monitor the shoreline for incoming high-altitude threats: missiles coming from across the ocean. Slow and cumbersome, and not nearly as user friendly as more modern equipment, the NEADS monochromatic radar displays are not designed to take internal FAA radar data or to identify radar tracks originating from inside the United States. The system offers little, if any, such low-level coverage over the country." [Spencer, 2008, pp. 31-32]

Several of the NEADS personnel will later complain of their inability to locate Flight 11 on their scopes (see Shortly After 8:37 a.m. September 11, 2001). But Master Sergeant Joe McCain, the mission crew commander technician at NEADS, believes he has located Flight 11 on the radar screen just before it crashes into the World Trade Center (see 8:45 a.m.-8:46 a.m. September 11, 2001).
