A number of fighter jets from Otis Air National Guard Base in Massachusetts that are out over the Atlantic Ocean on a training mission are notified of the first crash at the World Trade Center and then return to their base. The fighters belong to the 102nd Fighter Wing. [102nd Fighter Wing, 2001; 9/11 Commission, 1/7/2004 
; Richard, 2010, pp. 13-14; Airman, 9/3/2011] According to most accounts, six of the unit’s F-15 fighters are taking part in the training mission. [102nd Fighter Wing, 2001; North American Aerospace Defense Command, 9/11/2001; Cape Cod Times, 9/11/2006; Spencer, 2008, pp. 155] But Major Martin Richard, one of the pilots involved, will write in a 2010 book that eight F-15s are taking part. [Richard, 2010, pp. 10]
Fighters Recalled for ‘Possible Use’ – The fighters took off from Otis Air Base at 9:00 a.m. for their “defensive counter-air” mission in an area of military training airspace over the Atlantic Ocean, southeast of Long Island, known as “Whiskey 105” (see (9:00 a.m.-9:24 a.m.) September 11, 2001). [9/11 Commission, 10/14/2003 ; Airman, 9/3/2011] Following the second attack on the WTC at 9:03 a.m., commanders at Otis Air Base convened and decided to recall all aircraft out on training (see Shortly After 9:03 a.m. September 11, 2001). [Spencer, 2008, pp. 153-154] A member of staff at NORAD’s Northeast Air Defense Sector (NEADS) tells a colleague that the fighters in Whiskey 105 are being recalled to Otis for “possible use, so we’ve got more aircraft [on] standby.” [North American Aerospace Defense Command, 9/11/2001]
Controller Tells Fighters to Return to Base – The fighters are recalled to their base at around 9:25 a.m. [9/11 Commission, 10/14/2003 ; 9/11 Commission, 1/7/2004 ] Shortly after they arrive in Whiskey 105, Richard is called by an air traffic controller at the FAA’s Boston Center. [Cape Cod Times, 9/11/2006] Richard will later note that “for a controller to interrupt our training mission was out of the norm.” [Richard, 2010, pp. 13] According to Airman, the controller tells Richard: “There’s something going on in New York. I think you guys need to get back to your base.” [Airman, 9/3/2011] But Richard will recall that the controller says, “[A]n aircraft just crashed into the World Trade Center and I think you should return to base immediately.” Richard replies, “Copy,” meaning he understands. However, he will say: “I was a bit confused. I didn’t know the extent of the pandemonium residing just outside of our sterile training airspace.” [Richard, 2010, pp. 13]
Pilot Not Told Why Alert Jets Were Scrambled – Before taking off from Otis Air Base, Richard had seen the two of his unit’s fighters that are kept on “alert”—ready for immediate launch—taking off in response to the hijacked Flight 11 (see 8:46 a.m. September 11, 2001), but he had been unaware of why they were being scrambled (see (8:30 a.m.-8:59 a.m.) September 11, 2001). Therefore, Richard will recall, “When the FAA announced that the World Trade [Center] tower had been struck by an aircraft, I asked if this was why the alert pilots had been scrambled.” However, he will say, he “got no reply.” It is unclear whether the pilots on the training mission are informed of the aircraft hijackings at this time. Richard will recall, “[W]hen it came over the radio that it was a possible hijacking, it sure got our attention,” but he will not say when this radio communication occurs. [102nd Fighter Wing, 2001; Cape Cod Times, 9/11/2006]
Supervisor Tells Pilot to Get Back to Base – Richard hurriedly dials the radio frequency to contact Lieutenant Colonel Jon Treacy, his unit’s supervisor of flying, who controls flying operations from the ground. [Richard, 2010, pp. 13] Richard asks, “Do you need us back on base?” and Treacy replies, “Get back here as soon as you can.” [Cape Cod Times, 9/11/2006]
Fighters Have Too Much Fuel to Land – The fighters were split apart over the Whiskey 105 airspace for their training mission. Rather than spending time getting them back together, Richard orders the pilots to go back to base in flights of two jets. Furthermore, another problem will delay their return: the fighters all have too much fuel to be able to land. Therefore, Richard will write, “Rather than dump the fuel overboard, which would take upwards of six to nine minutes, we got together in twos and did some basic fighter maneuvering.” These maneuvers, which are done in full afterburner, are “the most expeditious way to get to landing weight.” As the pilots request clearance to fly out of Whiskey 105 and back to Otis Air Base, their radios become crowded with communications. Richard comments, “It sounds like we are at war.”
Pilots Told to Stay at Their Aircraft after Landing – The pilots still have little idea what is going on, so Richard contacts Treacy for an update. However, Treacy has nothing concrete to tell him and only says, “After you land, stay at your jets; we’ll run the classified packs out to you.” These “classified packs” fit into the leg pocket of a pilot’s g-suit, and include the classified codes and guidance pilots fly with when on alert. Richard will write, “In light of recent events, it seemed we had been drafted for alert duty.” [Richard, 2010, pp. 13-14]
Pilots Told to Prepare Fighters for Alert – The fighters arrive at Otis Air Base around 20 minutes after they are called back there, according to author Lynn Spencer. As they taxi in, the pilots receive an instruction over their radios from Treacy, who tells them, “Cock your jets for alert!” They have never received such an order before. It means that instead of parking and shutting down their aircraft, they must prepare them to be scrambled from the flight line, with all of the instruments, controls, and switches set ready for immediate takeoff orders. After doing as instructed, the pilots head into the operations building to find out what is happening. [Spencer, 2008, pp. 155] Most of the squadron personnel are huddled by the television in the break room, watching the coverage of the terrorist attacks. One of the life support technicians turns to Richard and says, “It’s a goddamn Tom Clancy novel!” Richard will comment, “It was obvious now that we were at war.” [Richard, 2010, pp. 14] A number of the fighters that come back from the training mission, which have no ordnance on them, will be armed and also refueled, ready to take off to protect US airspace. [102nd Fighter Wing, 2001] The first fighters to subsequently take off from Otis Air Base will launch at around 10:30 a.m. (see (10:30 a.m.) September 11, 2001 and (Shortly After 10:30 a.m.) September 11, 2001). [9/11 Commission, 10/14/2003 ; Spencer, 2008, pp. 244-246]
9:27 a.m. September 11, 2001: Boston Center Tells NEADS that Delta 1989 Is Missing
The FAA’s Boston Center contacts NORAD’s Northeast Air Defense Sector (NEADS) and reports that another aircraft, Delta Air Lines Flight 1989, is missing. [9/11 Commission, 5/23/2003; 9/11 Commission, 6/17/2003; 9/11 Commission, 2004] Why the Boston Center does this is unclear, since Delta 1989 is currently being handled by the FAA’s Cleveland Center, not the Boston Center. [USA Today, 8/13/2002; 9/11 Commission, 7/24/2004, pp. 10] And, according to the 9/11 Commission, Delta 1989 “never turned off its transponder,” so it should still be clearly visible on radar. [9/11 Commission, 7/24/2004, pp. 16, 28] Twelve minutes later, at 9:39, Boston Center will call NEADS and incorrectly tell it that Delta 1989 is a possible hijack (see 9:39 a.m. September 11, 2001). [9/11 Commission, 2004; Vanity Fair, 8/1/2006]
9:35 a.m. September 11, 2001: Boston Center and NEADS Decide to Send Home Fighter Jets on Training
The traffic management unit (TMU) at the FAA’s Boston Center calls NORAD’s Northeast Air Defense Sector (NEADS) to ask whether military planes out on training should be sent home. Boston Center asks, “The military aircraft that are in the air right now, we’re wondering if we should tell them to return to base if they’re just on training missions, or what you guys suggest?” NEADS replies, “No, they’re actually on the active air for the DO [director of operations] out there,” but adds, “We did send the ones home in 105 that were on the training mission.” This is presumably a reference to some fighters from Otis Air National Guard Base that were training in “Whiskey 105,” which is military training airspace southeast of Long Island (see (9:00 a.m.-9:24 a.m.) September 11, 2001 and (9:25 a.m.-9:45 a.m.) September 11, 2001). Boston Center mentions that there are other military aircraft still airborne for training, and asks, “In general, anybody that’s training?” After consulting with colleagues, the member of staff at NEADS tells Boston, “Yes, go ahead and send them home.” [North American Aerospace Defense Command, 9/11/2001] NEADS was involved in a major training exercise this morning, though this was reportedly canceled shortly after the second WTC tower was hit (see (Shortly After 9:03 a.m.) September 11, 2001). [Newhouse News Service, 1/25/2002; Airman, 3/2002]
9:39 a.m. September 11, 2001: Boston Center Informs NEADS of Possible Hijacking of Delta 1989
Colin Scoggins, the military liaison at the FAA’s Boston Center, contacts NORAD’s Northeast Air Defense Sector (NEADS) and incorrectly notifies it that another aircraft, Delta Air Lines Flight 1989, is a possible hijacking. [9/11 Commission, 2004; Vanity Fair, 8/1/2006] Boston Center previously called NEADS at 9:27 and said that Delta 1989 was missing (see 9:27 a.m. September 11, 2001). [North American Aerospace Defense Command, 9/11/2001; 9/11 Commission, 5/23/2003]
NEADS Technicians Respond – At NEADS, Stacia Rountree, the ID technician who takes Scoggins’s call, announces to her colleagues: “Delta ‘89, that’s the hijack. They think it’s possible hijack.… South of Cleveland.” The plane’s transponder is still on, and she adds, “We have a code on him now.” Rountree’s team leader, Master Sergeant Maureen Dooley, instructs: “Pick it up! Find it!” The NEADS technicians quickly locate Delta 1989 on their radar screens, just south of Toledo, Ohio, and start alerting other FAA centers to it. [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 177] NEADS mission crew commander Major Kevin Nasypany will be notified by his staff of the suspected hijacking at about 9:41 or 9:42 a.m. [9/11 Commission, 1/22/2004 ] NEADS never loses track of Delta 1989. It will follow it on radar as it reverses course over Toledo, heads east, and then lands in Cleveland (see (10:18 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 28] It will order Air National Guard fighter jets from Selfridge and Toledo to intercept the flight (see (9:55 a.m.) September 11, 2001 and 10:01 a.m. September 11, 2001). [Spencer, 2008, pp. 178-179] But it will soon learn that Delta 1989 is not in fact hijacked. [9/11 Commission, 7/24/2004, pp. 28]
Cleveland Center, Not Boston, Handling Delta 1989 – Although Boston Center notifies NEADS of the suspected hijacking, Delta 1989 is in fact being handled by the FAA’s Cleveland Center. [USA Today, 8/13/2002; 9/11 Commission, 7/24/2004, pp. 10-12] Cleveland Center air traffic controllers suspected that Delta 1989 had been hijacked at around 9:30 a.m. (see (9:28 a.m.-9:33 a.m.) September 11, 2001), but apparently only informed the FAA’s Command Center, and not NEADS, of this. [USA Today, 8/13/2002] To explain why Boston Center alerts NEADS to the flight, the 9/11 Commission will later comment that, “Remembering the ‘we have some planes’ remark” (see 8:24 a.m. September 11, 2001), the Boston Center simply “guessed that Delta 1989 might also be hijacked.”
Similar to First Two Hijacked Planes – Like Flights 11 and 175, the two aircraft that have crashed into the World Trade Center (see 8:46 a.m. September 11, 2001 and 9:03 a.m. September 11, 2001), Delta 1989 took off from Boston’s Logan Airport. [9/11 Commission, 7/24/2004, pp. 27-28] According to the New York Times, it left there at about the same time as Flights 11 and 175 did, meaning around 8:00 to 8:15 a.m. [New York Times, 10/18/2001; 9/11 Commission, 7/24/2004, pp. 32] Like those two aircraft, it is a Boeing 767. [USA Today, 8/13/2002; 9/11 Commission, 7/24/2004, pp. 27-28] But, unlike those flights, its transponder has not been turned off, and so it is still transmitting a beacon code. [9/11 Commission, 7/24/2004, pp. 28; Vanity Fair, 8/1/2006] It is unclear what Delta 1989’s intended destination is. According to some accounts, like Flights 11 and 175 were, it is bound for Los Angeles. [Associated Press, 9/11/2001; New York Times, 10/18/2001; USA Today, 8/13/2002; Arizona Daily Star, 9/24/2007; Spencer, 2008, pp. 167] Other accounts will say that its destination is Las Vegas. [9/11 Commission, 7/24/2004, pp. 28; Vanity Fair, 8/1/2006] Personnel at NEADS are apparently informed that Las Vegas is the intended destination. Around this time, one member of staff there tells her colleagues that the flight is “supposed to go to Vegas.” [North American Aerospace Defense Command, 9/11/2001]
One of Numerous Incorrect Reports – The 9/11 Commission will comment: “During the course of the morning, there were multiple erroneous reports of hijacked aircraft (see (9:09 a.m. and After) September 11, 2001). The report of American 11 heading south was the first (see 9:21 a.m. September 11, 2001); Delta 1989 was the second.” [9/11 Commission, 7/24/2004, pp. 28]
Shortly After 10:20 a.m. September 11, 2001: FAA’s Boston Center Declares ‘ATC Zero’
Managers at the FAA’s Boston Center declare “air traffic control zero” (“ATC zero”), which completely shuts down the center’s airspace, after a report is received of a possible airborne threat to their facility. [Federal Aviation Administration, 9/20/2001; Spencer, 2008, pp. 243] The Boston Center in Nashua, New Hampshire, has received a call from the FAA’s New England regional office, informing it that an unidentified aircraft is heading its way. In response, the center’s managers immediately order the evacuation of the facility (see (Shortly After 10:20 a.m.) September 11, 2001). At the same time, they make the declaration of ATC zero. [Spencer, 2008, pp. 243] The declaration of ATC zero means aircraft are not permitted to depart from, arrive at, or travel through the center’s airspace until further notice. [9/11 Commission, 8/26/2004, pp. 24] According to author Lynn Spencer, ATC zero means all the aircraft a center is handling are pushed “onto neighboring sectors, and any new airplanes from adjacent sectors are turned back, at the sector boundaries if necessary.” [Spencer, 2008, pp. 68] Although the exact time the managers declare ATC zero at is unclear, the Boston Center notifies the FAA’s Herndon Command Center of the declaration at 10:35 a.m. At 11:41 a.m., the ATC zero alert at the Boston Center is canceled. [Federal Aviation Administration, 3/21/2002] The FAA’s New York Center declared ATC zero at 9:05 a.m. (see 9:05 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 24]
Shortly After 10:20 a.m. September 11, 2001: Boston Air Traffic Control Center Evacuated following Report of Airborne Threat
The FAA’s Boston Center is evacuated after it receives a report that an unidentified aircraft is heading its way. [Federal Aviation Administration, 9/20/2001; USA Today, 8/11/2002; New Hampshire Union Leader, 9/11/2006; Spencer, 2008, pp. 243] The Boston Center, located in Nashua, New Hampshire, manages air traffic above New England, and monitored Flight 11 and Flight 175 earlier on. [USA Today, 8/11/2002; Associated Press, 8/12/2002] Employees there are already concerned because a large tractor-trailer has parked directly in front of their facility, on New Hampshire’s Route 3. State police have been called to get it away from there.
Possible Airborne Threat Leads to Evacuation – The FAA’s New England regional office in Burlington, Massachusetts, now calls the Boston Center and reports that an unidentified aircraft is heading for the facility. In response to this potential threat, managers at the center immediately order the closure and evacuation of their building. They also declare “ATC zero,” which shuts down the Boston Center’s airspace (see (Shortly After 10:20 a.m.) September 11, 2001). Employees run from the building while managers try to decide which, if any, personnel should remain in the facility. According to Colin Scoggins, the center’s military liaison, “at this time we honestly felt that we were targeted and an impact was imminent.”
Bomb Threat to Childcare Facility – Making matters worse, a bomb scare phone call is received at the center’s childcare facility, which is the employees’ usual evacuation point. Center managers therefore decide that everyone must leave the building. Employees are advised to go to either 11 Murphy Drive—an FAA administrative facility—or a nearby Holiday Inn. According to Scoggins, three or four Flight Service Data Processing System personnel remain in the basement of the Boston Center when it is evacuated, apparently because there is no paging system in their office on which they can receive the evacuation order.
Evacuation Time Unclear – The time the evacuation takes place at is unclear. According to the account of author Lynn Spencer, it occurs some time shortly after 10:20 a.m. [Federal Aviation Administration, 9/20/2001; USA Today, 8/11/2002; Spencer, 2008, pp. 242-243] At 10:34 a.m., John White, a manager at the FAA’s Command Center, reports that the Boston Center “has received a threat,” and is “going down to skeleton staffing.” [9/11 Commission, 11/4/2003] A 10:52 a.m. entry in the log of the FAA headquarters’ teleconference will state that the Boston Center is “evacuating the building.” [Federal Aviation Administration, 3/21/2002] USA Today will report that the center is evacuated at “about 11 a.m.”
Few Employees Return to Building – About 30 minutes to an hour after the building is evacuated, some of the center’s personnel will return to work. [Federal Aviation Administration, 9/20/2001; USA Today, 8/11/2002] By 12:16 p.m., the center is back in operation, but with only a skeleton staff. [Federal Aviation Administration, 3/21/2002]
Suspicious Aircraft Only a Coast Guard Plane – As it turns out, the approaching aircraft that prompts the evacuation is just a Coast Guard plane. According to Scoggins, “We had already identified it.” [Federal Aviation Administration, 9/20/2001] The aircraft was noted in a 10:18 a.m. entry in the log of the FAA headquarters’ teleconference, which stated: “Aircraft 160 miles east of Nantucket is headed westbound toward Boston at a high rate of speed.” But a log entry five minutes later, at 10:23 a.m., noted that the aircraft “is identified as a Coast Guard flight from Nantucket.” [Federal Aviation Administration, 3/21/2002] Shortly before the Boston Center is alerted to this aircraft, Scoggins had been tracking what is apparently another unidentified target on his radar screen: a slow-moving large aircraft that is also flying toward the Boston Center from the east (see (10:20 a.m.) September 11, 2001). [Spencer, 2008, pp. 242-243] The identity of that aircraft is unclear.
