The Federal Aviation Administration (FAA) holds a training exercise based on the scenario of an aircraft hijacking, which involves a real plane playing the part of the hijacked aircraft. The exercise will be described to the 9/11 Commission in 2004 by Major Paul Goddard, who is the chief of live exercises for the North American Aerospace Defense Command (NORAD) at the time of the 9/11 attacks. According to Goddard, the exercise, held in 1995, is called “Twin Star” and the FAA invites NORAD to participate in it, “since a real commercial airliner was to be shadowed by a fighter intercept.” Goddard will tell the 9/11 Commission his understanding is that the exercise involves the entire FAA system, and the National Military Command Center (NMCC) at the Pentagon also participates in it. [9/11 Commission, 3/4/2004] Colin Scoggins, the military operations specialist at the FAA’s Boston Center on 9/11, will describe what is apparently this exercise when he is interviewed by the 9/11 Commission in 2003. He will say he believes the exercise is “joint FAA/military” and is conducted “in 1995 or 1996.” According to Scoggins, the exercise involves “a military scramble to escort a hijacked aircraft,” but the fighter jets taking part are “unable to intercept” the mock hijacked plane. [9/11 Commission, 9/22/2003 
] Apparently describing the same exercise in a documentary film, Scoggins will say, “We had run a hijack test years before [9/11] and the fighters never got off on the appropriate heading, and it took them forever to catch up.” [Michael Bronner, 2006]
8:25 a.m.-8:35 a.m. September 11, 2001: Military Liaison Arrives Late at Boston Center, Learns of First Hijacking
Colin Scoggins, the military liaison at the FAA’s Boston Center, arrives at work an hour late and is informed of the hijacking of Flight 11. [Federal Aviation Administration, 9/20/2001; WAMU, 8/3/2006; Spencer, 2008, pp. 32-33] Scoggins is an experienced air traffic controller and specializes in airspace, procedures, and military operations. He is responsible for managing operating agreements between the Boston Center and other air traffic control facilities, and between Boston Center and the military. He is also responsible for generating the military schedules that keep FAA facilities synchronized with military airspace requirements, and has therefore developed personal relationships with most of the military units in his region. [Spencer, 2008, pp. 32-33]
Arrives One Hour Late – In a 2006 radio interview, Scoggins will recall that he arrives at work one hour late, saying, “That morning I actually came in, took an hour early on the front of my shift, so I didn’t get in until 8:30.” [WAMU, 8/3/2006] But in a statement that will be provided to the 9/11 Commission, he says he arrives at the Boston Center slightly earlier, at “about 8:25 a.m.” [Federal Aviation Administration, 9/20/2001] When he enters the building, a colleague tells him about the hijacking of Flight 11. [Spencer, 2008, pp. 33]
Heads to Credit Union – Rather than going immediately to help deal with the hijacking, Scoggins heads to the credit union at the center. He will recall, “I wasn’t in a rush because when hijacks do occur, sometimes too many people try to get involved, but instead they just get in the way.”
Mentions that Hijacked Plane Could Hit a Building – When he gets to the credit union, Scoggins decides he should go to the center’s traffic management unit, to make sure that fighter jets are launched in response to the hijacking. As he will later recall, he says to an employee at the credit union that “if it really came to it,” and fighter jets “had to stop the hijack from hitting a building or something, there wasn’t much [the fighters] could do.” [Federal Aviation Administration, 9/20/2001]
Updated on Hijacking – Scoggins then heads to the center’s operational floor, arriving there at about 8:35. [WAMU, 8/3/2006; Griffin, 2007, pp. 335] He goes to the traffic management unit and the desk of Daniel Bueno, who is the unit’s supervisor. Bueno brings Scoggins up to date on the details of the hijacking. He tells him: “It sounds real. We heard a Mideastern or Arabic voice on radio. They’ve also turned off the transponder to prevent the hijack code from appearing.” Bueno says the Boston Center controllers are still tracking the primary radar return for Flight 11, but they lack information on its altitude. According to author Lynn Spencer, it occurs to Scoggins that NORAD’s Northeast Air Defense Sector (NEADS) might be able to provide altitude information for Flight 11, “because the FAA radar system filters out certain altitude information that NEADS gets.” He will therefore phone NEADS as soon as he arrives at his station (see (8:35 a.m.) September 11, 2001). [Spencer, 2008, pp. 33]
8:35 a.m. September 11, 2001: Boston Center Military Liaison Makes His First Call to NEADS, Though 9/11 Commission Does Not Mention It
Colin Scoggins, the military liaison at the FAA’s Boston Center, claims he makes his first call to NORAD’s Northeast Air Defense Sector (NEADS) regarding Flight 11. He later recalls that he informs NEADS that the aircraft is “20 [miles] south of Albany, heading south at a high rate of speed, 600 knots.” [Griffin, 2007, pp. 43] Flight 11 was over Albany at 8:26 (see (8:26 a.m.-8:29 a.m.) September 11, 2001). [Federal Aviation Administration, 9/17/2001 ] At such a high speed, it would have reached 20 miles south of there around 8:28. However, Scoggins says he is quite certain he only arrives on the floor at Boston Center at around 8:35. He says that although he’d later tried to write up a chronology of events, he “couldn’t get a timeline that made any sense.” Furthermore, Scoggins claims that even before he’d arrived, Joseph Cooper, a Boston Center air traffic management specialist, had already phoned NEADS about the hijacking. [Griffin, 2007, pp. 43 and 335] The 9/11 Commission makes no mention of either call. It says “the first notification received by the military—at any level—that American 11 had been hijacked” is when Boston Center calls NEADS just before 8:38 a.m. (see (8:37 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] However, a report by ABC News is more consistent with Scoggins’ claims, indicating that Boston Center contacts NEADS about the hijacking earlier, at around 8:31. [ABC News, 9/11/2002] (Boston Center also contacts the FAA’s Cape Cod facility at 8:34 and requests that it notify the military about Flight 11 (see 8:34 a.m. September 11, 2001). Apparently around the same time, it tries contacting a military unit at Atlantic City (see (8:34 a.m.) September 11, 2001).) Scoggins says he makes “about 40 phone calls to NEADS” in total on this day. [Griffin, 2007, pp. 43] NEADS Commander Robert Marr later comments that Scoggins “deserves a lot of credit because he was about the only one that was feeding us information. I don’t know exactly where he got it. But he was feeding us information as much as he could.” [Michael Bronner, 2006]
Shortly After 8:37 a.m. September 11, 2001: NEADS Staff Unable to Locate Hijacked Planes on Radar Screens
Members of staff at NORAD’s Northeast Air Defense Sector (NEADS) have difficulty locating Flight 11 and other aircraft on their radar screens. 
Lt. Col. Dawne Deskins of NEADS will say that when the FAA first calls and reports the first hijacking (see (8:37 a.m.) September 11, 2001), “He [FAA] gave me the latitude and longitude of that track… [but] there was nothing there.” [Fox News, 9/8/2002] Colin Scoggins, the military liaison at the FAA’s Boston Center, later recalls: “I was giving NEADS accurate location information on at least five instances where AA 11 was, yet they could never identify him.… I originally gave them an F/R/D, which is a fix/radial/distance from a known location; they could not identify the target. They requested latitude/longitudes, which I gave them; they still could not identify the AA 11.… I gave them 20 [miles] south of Albany heading south at a high rate of speed, 600 knots, then another call at 50 south of Albany.” [Griffin, 2007, pp. 47] Master Sergeant Kevin Foster and Staff Sergeant Mark Rose, also working at NEADS this morning, later complain about their inability to locate the hijacked planes. After being informed of the first hijacking, reportedly: “As they had practiced countless times before, the NEADS team quickly began searching their [radar] screens for the plane. Because they had been informed its transponder was off, they knew to look for a tiny dash instead of the usual dot. But radar systems also use such lines to indicate weather patterns, so NEADS personnel began urgently clicking their computer cursors on each stray line to see if information indicating an aircraft would appear.” Yet, after receiving further calls indicating more hijackings, “the inability to find the hijacked planes on the radar, despite their best efforts, was difficult.” According to Foster, “We were trying to find the tracks, and not being able to was very frustrating.” [Utica Observer-Dispatch, 8/5/2004] NEADS Staff Sergeant Larry Thornton will recall: “Once we were called by the FAA, we could find split-second hits on what we thought we were looking for. But the area was so congested and it was incredibly difficult to find. We were looking for little dash marks in a pile of clutter and a pile of aircraft on a two-dimensional scope.” Each fluorescent green pulsating dot on their radar scopes represents an airplane, and there are thousands currently airborne, especially over the busy northeast US. [Filson, 2003, pp. 56]
8:38 a.m. September 11, 2001: Boston Center Military Liaison Updates NEADS on Flight 11
Colin Scoggins, the military liaison at the FAA’s Boston Center, makes a brief phone call to NORAD’s Northeast Air Defense Sector (NEADS) to see if it has been able to find any further information about Flight 11. [Spencer, 2008, pp. 32-33] Boston Center has just alerted NEADS to the hijacking of Flight 11 (see (8:37 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20] Scoggins asks the ID technician who answers his call, “Have you identified the radar target for American 11?” The ID tech says they are still searching for it. Scoggins then tells her that Flight 11 is “50 miles south of Albany,” but, according to author Lynn Spencer, this information “won’t be of much help to NEADS Surveillance,” because “[t]heir monochromic displays aren’t even capable of showing the outline of states, much less those of cities like Albany or New York.” [Spencer, 2008, pp. 33] (However, despite this supposed inadequate capability, NEADS is reportedly able to spot Flight 11 shortly before it crashes into the World Trade Center (see 8:45 a.m.-8:46 a.m. September 11, 2001), locating its radar track “going down the Hudson Valley, straight in from the north toward New York.” [Filson, 2003, pp. 56] ) As NEADS has no new information to offer him, Scoggins quickly ends the call. According to Spencer’s account, this is the first time Scoggins calls NEADS this morning, after arriving at the Boston Center minutes earlier (see (8:25 a.m.-8:35 a.m.) September 11, 2001). [Spencer, 2008, pp. 33] But according to a description Scoggins gives to author David Ray Griffin in 2007, it appears that this is his second call, after an initial call at around 8:35 (see (8:35 a.m.) September 11, 2001). Scoggins will tell Griffin that he first called NEADS to inform it that Flight 11 was “20 [miles] south of Albany heading south at a high rate of speed, 600 knots,” and then he makes “another call at 50 [miles] south of Albany.” [Griffin, 2007, pp. 47]
8:40 a.m. September 11, 2001: NEADS Learns of Threat to Flight 11 Cockpit
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!” [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 34]
Between 8:40 a.m. and 8:46 a.m. September 11, 2001: NEADS Calls Atlantic City Unit, but Phone Is Not Answered
Colin Scoggins, the military liaison at the FAA’s Boston Center, calls NORAD’s Northeast Air Defense Sector (NEADS) and suggests that it contact a military unit at Atlantic City, New Jersey. However, when NEADS tries phoning the unit, the call is not answered.
Scoggins Notices Otis Jets Not Yet Launched – Scoggins had called NEADS at around 8:38 a.m., regarding the hijacked Flight 11 (see (8:38 a.m.) September 11, 2001). A few minutes after this, he notices that fighter jets have not yet launched from Otis Air National Guard Base, at Cape Cod, Massachusetts, and calls NEADS again. He suggests that it should try to get jets launched from Atlantic City. [Spencer, 2008, pp. 32-34] Atlantic City International Airport is the home of the 177th Fighter Wing of the New Jersey Air National Guard. [GlobalSecurity (.org), 8/21/2005] As author Lynn Spencer will describe, Scoggins “knows that Atlantic City is no longer an alert facility, but he also knows that they launch F-16s for training flights every morning at nine. He figures that the pilots are probably already in their planes and ready to go. They’re unarmed, but they’re a lot closer to New York City than the Otis fighters on Cape Cod, and the military serves only a monitoring purpose in hijacking anyway.” [Spencer, 2008, pp. 33-34] Two F-16s from the 177th Fighter Wing are in fact already airborne and performing their training mission, and are just a few minutes flying time from New York City (see 8:46 a.m.-9:03 a.m. September 11, 2001). [Bergen Record, 12/5/2003] Scoggins will later recount: “I requested that we take from Atlantic City very early in the [morning], not launch from the ground but those already airborne in Warning Area 107 [a training area] if they were there, which I believe they were.” He will add that the 177th Fighter Wing does not “have an intercept mission; it was taken away a long time ago. [But] NEADS could have called them and asked them to cancel their [training] mission and divert.” [Griffin, 2007]
NEADS Tries Unsuccessfully to Contact Unit – The NEADS technician who takes Scoggins’s call follows his advice, and tries to call the unit at Atlantic City. He calls the only number he has for it, which is the number NEADS had previously called when it wanted to scramble 177th Fighter Wing F-16s until 1998, back when they were part of NORAD’s alert force. The number connects the technician directly to the highly secured command post. However, no one answers the phone. According to Spencer: “[T]hese days, the command post is more of a highly secured storage area, opened just once a month for drill weekends. The phone rings and rings.” [Spencer, 2008, pp. 34] The FAA’s Boston Center also attempted to call the Atlantic City unit, apparently several minutes earlier (see (8:34 a.m.) September 11, 2001). The outcome of that call is unstated. [9/11 Commission, 7/24/2004, pp. 20]
Between 8:40 a.m. and 8:54 a.m. September 11, 2001: Boston Center Military Liaison Calls New York Center with Report about Flight 11; Timing Unclear
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 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 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]
8:45 a.m.-8:46 a.m. September 11, 2001: NEADS Technician Locates Flight 11 on Radar Screen, Then Sees It Disappear over New York
Master Sergeant Joe McCain, the mission crew commander technician at NORAD’s Northeast Air Defense Sector (NEADS), believes he has located Flight 11 on the radar screen and then watches it disappear over New York, but he does not realize it has crashed. McCain is on the phone with Colin Scoggins, the military liaison at the FAA’s Boston Center. [Spencer, 2008, pp. 40-41] NEADS personnel have been unable to locate Flight 11 on their radar screens (see Shortly After 8:37 a.m. September 11, 2001). [Utica Observer-Dispatch, 8/5/2004]
McCain Locates Fast-Moving Aircraft – Now McCain believes he has found Flight 11, flying about 20 miles north of Manhattan. According to author Lynn Spencer, he “knows that planes tend to fly very specific routes, like highways in the sky, and this particular target seems not to be on any of those regular routes. It’s also very fast moving.” McCain tells Scoggins, “I’ve got a search target that seems to be on an odd heading here,” and then describes its location. Scoggins notices the target, but this is not Flight 11. Scoggins then realizes that Flight 11 is right behind the target McCain has identified, and yells to him: “There’s a target four miles behind it, that’s the one! That’s American 11!” McCain responds, “I’ve got it!” The aircraft is 16 miles north of New York’s JFK International Airport, and heading down the Hudson River valley. NEADS has no altitude for it, but the aircraft is clearly traveling very fast. After hanging up the phone, McCain calls out its coordinates to everyone on the NEADS operations floor. [Spencer, 2008, pp. 40] McCain will later recall: “It’s very unusual to find a search target, which is a plane with its transponder turned off, in that area. This plane was headed toward New York going faster than the average Cessna and was no doubt a jet aircraft. We had many clues. The plane was fast and heading in an unusual direction with no beacon. We had raw data only. Everything just kind of fit.” [Filson, 2003, pp. 56-57] (The identity of the other fast-moving aircraft McCain had noticed, four miles ahead of Flight 11, is unstated.)
Flight 11 Disappears from Radar – Less than a minute after McCain locates the track for Flight 11, it disappears. [Spencer, 2008, pp. 41] McCain will recall, “We watched that track until it faded over New York City and right after that someone came out of the break room and said the World Trade Center had been hit.” [Filson, 2003, pp. 57] However, McCain supposedly does not realize that the plane he had spotted has crashed into the WTC. According to Spencer: “[H]e knows only that the blip he has struggled so mightily to locate has now vanished. He figures that the plane has descended below his radar coverage area to land at JFK. The fact that the plane was flying much too fast for landing does not hit him; the concept that the plane might have been intentionally crashed is simply too far outside his realm of experience.” [Spencer, 2008, pp. 41]
8:46 a.m. September 11, 2001: Boston Center Notices Flight 11 Disappear from Its Radar Screens, Does Not Realize It Has Crashed
Flight 11 disappears from primary radar four seconds before it hits the North Tower of the World Trade Center (see 8:46 a.m. September 11, 2001), according to an FAA timeline. [Federal Aviation Administration, 9/17/2001 ] At the FAA’s Boston Center, Colin Scoggins, the center’s military liaison, notices the loss of the plane’s primary radar track. As the center only monitors high-level air traffic, its radar information does not pick up aircraft below 1,500 feet. But Scoggins does not realize Flight 11 has crashed. The Boston Center’s last known position for the plane before it disappears is nine miles northeast of New York’s JFK International Airport. [Spencer, 2008, pp. 49]
