Colin Scoggins, the military liaison at the FAA’s Boston Center, calls NORAD’s Northeast Air Defense Sector (NEADS) to report a low-flying airliner he has spotted six miles southeast of the White House. He can offer no details regarding its identity. The plane is reportedly Flight 77, but as it has its transponder turned off, no one realizes this at the time. The news of the plane “sets off a frenzy.” Major Kevin Nasypany orders Major James Fox, head of the NEADS weapons team, “Get your fighters there as soon as possible!” Staff Sergeant William Huckabone says, “Ma’am, we are going AFIO [emergency military control of the fighters] right now with Quit 2-5 [the Langley Air Force Base fighters]” (see 9:36 a.m. September 11, 2001), and adds, “They are going direct Washington.” [Vanity Fair, 8/1/2006] The Langley fighters will arrive over Washington some time around 10 a.m. (see (Between 9:49 a.m. and 11:00 a.m.) September 11, 2001).
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]
9:40 a.m. September 11, 2001: Hijacking Simulation Scheduled as Part of NORAD Exercise
As part of a NORAD training exercise, a simulated plane hijacking was scheduled to occur around this time. It was to have been based around politically motivated perpetrators taking command of an aircraft, landing it on a Cuba-like island, and seeking asylum there. The hijacking was one of several simulated scenarios prepared for the day. Details of the other scenarios are unknown. Major Kevin Nasypany, the mission crew commander at NORAD’s Northeast Air Defense Sector (NEADS) who’d helped designed the exercise, initially thought the reports of Flight 11 being hijacked were because “Somebody started the exercise early.” [Vanity Fair, 8/1/2006] The exercise was canceled after the second plane hit the World Trade Center (see (Shortly After 9:03 a.m.) September 11, 2001).
Shortly After 9:41 a.m. September 11, 2001: NEADS Tries Unsuccessfully to Get Minnesota Jets Scrambled after Delta 1989
NORAD’s Northeast Air Defense Sector (NEADS) tries to get fighter jets from a military unit in Duluth, Minnesota, sent after Delta Air Lines Flight 1989, but the unit is unable to respond. [9/11 Commission, 1/22/2004 ] NEADS has been contacted by the FAA’s Boston Center and incorrectly told that Delta 1989 is a possible hijacking (see 9:39 a.m. September 11, 2001). The aircraft is just south of Toledo, Ohio, and Colonel Robert Marr and Major Kevin Nasypany order the troops at NEADS to call Air National Guard bases in that area to see if any of them can launch fighters. [9/11 Commission, 2004; Vanity Fair, 8/1/2006]
NEADS Calls Duluth – The staff attempts to get a unit in Duluth to send jets toward the Delta flight. [9/11 Commission, 1/22/2004 ; 9/11 Commission, 1/23/2004 ] Presumably the unit they call is the 148th Fighter Wing of the Minnesota Air National Guard, which is located at the Duluth International Airport and flies the F-16 Fighting Falcon. [GlobalSecurity (.org), 8/21/2005] Unlike Otis Air National Guard Base and Langley Air Force Base, the 148th FW at Duluth is not one of NORAD’s seven “alert” sites around the US. However, its mission does include “air superiority and air defense functions.” [Airman, 12/1999; US Air Force, 2004; 9/11 Commission, 7/24/2004, pp. 17]
Duluth Has ‘Nobody Available’ – The Duluth unit is unable to respond to NEADS’s request for help. [9/11 Commission, 1/22/2004 ] The reason for this is unclear. At 9:46 a.m., a member of staff on the NEADS operations floor will report that “Duluth has night flying, so there’s nobody available.” [North American Aerospace Defense Command, 9/11/2001; Donaldson and Johnson, 6/2008, pp. 47 ] Marr will subsequently instruct NEADS personnel to contact every Air National Guard unit in the Northeast US with instructions to get their fighters airborne (see (Between 9:50 a.m. and 10:00 a.m.) September 11, 2001). NEADS will also order Air National Guard jets from Selfridge and Toledo to intercept Delta 1989 (see (9:55 a.m.) September 11, 2001 and 10:01 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 28; Spencer, 2008, pp. 178-180]
9:58 a.m. September 11, 2001: NEADS Requests Help from Western Air Defense Sector
Major Kevin Nasypany, the mission crew commander at NORAD’s Northeast Air Defense Sector (NEADS), calls NORAD’s Western Air Defense Sector (WADS), which is at McChord Air Force Base in Washington State, to request assistance. He says: “I’d like to… steal some aircraft out of Fargo from you guys.… Bring up the weapons too, if possible,” to which WADS replies: “Yep, ok. We will do that.” [North American Aerospace Defense Command, 9/11/2001] The three F-16s launched from Langley Air Force Base at 9:30 (see (9:25 a.m.-9:30 a.m.) September 11, 2001) are in fact from the North Dakota Air National Guard’s 119th Fighter Wing, which, though based at Fargo, ND, has had a detachment of two F-16s on alert at Langley since late 2000. However, these are under the command of NEADS, not WADS. [Virginian-Pilot, 9/22/2001; New York Times, 10/16/2001; McChord Air Museum, 2007] It is therefore not clear what specific fighters are now being referred to when Nasypany speaks of the “aircraft out of Fargo,” nor is it clear if and when these planes are launched. Colonel John Cromwell, the commander of WADS, will later recall that he calls every fighter wing commander west of the Mississippi, and by midday (3:00 p.m. ET) has more than 100 fighter jets on alert. [News Tribune (Tacoma, WA), 6/3/2006]
10:00 a.m. September 11, 2001: NEADS Commander Complains about Senior Officer Interfering on Operations Floor
Major Kevin Nasypany, the mission crew commander at NORAD’s Northeast Air Defense Sector (NEADS), complains about Lieutenant Colonel Ian Sanderson—an officer from the NEADS battle cab—spending time on the operations floor, where, Nasypany says, he has been “circumventing my system.” [North American Aerospace Defense Command, 9/11/2001] Sanderson is the NEADS Sector Operations Control Center (SOCC) director. He is also beginning his training as a fighter director on this day. [9/11 Commission, 10/29/2003 ] He is one of a number of senior personnel working in the battle cab, which is a glass-walled room overlooking the NEADS operations floor. [Filson, 2003, pp. 55; 9/11 Commission, 10/30/2003 ] However, he has also been spending time on the operations floor.
Director Is ‘Circumventing My System’ – Nasypany therefore now complains, “Got to get Ian [Sanderson] off the floor.” He adds that Sanderson has been “on it, circumventing my system here.” [North American Aerospace Defense Command, 9/11/2001] (As the mission crew commander (MCC), Nasypany is supposed to be in charge of the entire operations floor. [Spencer, 2008, pp. 25] ) He continues with his complaint, saying that Sanderson is “not an MCC” and so he “needs to stay up there” in the battle cab. [North American Aerospace Defense Command, 9/11/2001]
Director Says He ‘Did Not Interfere’ – Despite Nasypany’s grievance that he has been “circumventing my system,” Sanderson will tell the 9/11 Commission that his “first inclination” after the first World Trade Center tower was hit had been to “step back and let everyone do their jobs.” He will say that in “wartime”—presumably referring to situations like the present crisis—“there really is no function for the SOCC director.” His role on this day is therefore, partly, “to stay out of everyone’s way.” Sanderson will also say he is “parental” to the NEADS personnel, and, in contrast with Nasypany’s complaint about him, will say he “did not interfere.”
Director Responsible for Recalling Off-Duty Personnel – The SOCC director, according to Sanderson, serves as “an internal look at the operations on the SOCC [operations] floor,” and “involves manning and procedures of floor operations.” On this day, Sanderson is responsible for ensuring that the operations floor has additional personnel, and for coordinating fighter jets from bases that are not NORAD assets. Sanderson will say he is “primarily concerned with calling back the operations personnel” who are off duty. [9/11 Commission, 10/29/2003 ]
10:05 a.m.-10:08 a.m. September 11, 2001: NEADS Alerted to Flight 93, Reportedly for the First Time
The military liaison at the FAA’s Cleveland Center calls NORAD’s Northeast Air Defense Sector (NEADS) and alerts it to the hijacked Flight 93. According to the 9/11 Commission, this is the first notification NEADS receives about Flight 93, but it comes too late, since the plane has already crashed (see (10:06 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 30; 9/11 Commission, 8/26/2004, pp. 46]
‘Bomb on Board’ Flight 93 – At 10:05 a.m., the military liaison at the Cleveland Center, who is unaware that Flight 93 has just crashed, calls NEADS to inform it that Flight 93 is heading toward Washington, DC. Even though communicating with NEADS is not one of his responsibilities, he wants to make sure it is in the loop. [Spencer, 2008, pp. 224] At NEADS, the call is answered by Tech Sergeant Shelley Watson. Shortly into the call, at 10:07, the military liaison tells her: “We got a United 93 out here. Are you aware of that?” He continues, “That has a bomb on board.” Watson asks: “A bomb on board? And this is confirmed? You have a mode three [beacon code], sir?” The military liaison replies, “No, we lost his transponder” (see (9:40 a.m.) September 11, 2001). The news about Flight 93 is shouted out to Major Kevin Nasypany, the NEADS mission crew commander. Nasypany responds: “Gimme the call sign. Gimme the whole nine yards.… Let’s get some info, real quick. They got a bomb?”
Liaison Wants Fighters Sent toward Flight 93 – The military liaison continues, asking Watson if NEADS scrambled fighter jets in response to Delta 1989, an aircraft that was mistakenly reported as having been hijacked (see (9:28 a.m.-9:33 a.m.) September 11, 2001 and 9:39 a.m. September 11, 2001). Watson replies: “We did. Out of Selfridge and Toledo” (see (9:55 a.m.) September 11, 2001 and 10:01 a.m. September 11, 2001), and says these jets are airborne. When the military liaison asks if the fighters can be directed to where Flight 93 is, Watson asks him if the Cleveland Center has latitude and longitude coordinates for this aircraft. The military liaison replies that he has not got this information available right now. All he knows is that Flight 93 has “got a confirmed bomb on board… and right now, his last known position was in the Westmoreland area.… Which is… in the Pittsburgh, Pennsylvania, area.” [North American Aerospace Defense Command, 9/11/2001; Vanity Fair, 8/1/2006]
NEADS Searches on Radar – The news of a bomb on board Flight 93 spreads quickly at NEADS, and personnel there search for the aircraft’s primary return on their radar screens. But because the plane has already crashed, they will be unable to locate it. NEADS will only learn that Flight 93 has crashed at 10:15 a.m., during a call with the FAA’s Washington Center (see 10:15 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 30-31]
FAA Failed to Notify Military Earlier – The Cleveland Center’s notification to NEADS about Flight 93 comes 39 minutes after the plane was hijacked (see (9:28 a.m.) September 11, 2001) and 33 minutes after FAA headquarters was alerted to the hijacking (see 9:34 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 11, 28] At the time NEADS is alerted to Flight 93, NORAD is similarly uninformed about this aircraft, according to the 9/11 Commission. The Commission will state, “At 10:07, its representative on the air threat conference call stated that NORAD had ‘no indication of a hijack heading to DC at this time.’” According to the Commission, the National Military Command Center (NMCC) at the Pentagon learned about the Flight 93 hijacking slightly earlier on, at 10:03 a.m. (see 10:03 a.m. September 11, 2001). However, the NMCC was notified by the White House, not the FAA. [9/11 Commission, 7/24/2004, pp. 42] A former senior FAA executive, speaking on condition of anonymity, will later try to explain why it takes the FAA so long to alert NEADS to Flight 93. He will say, “Our whole procedures prior to 9/11 were that you turned everything [regarding a hijacking] over to the FBI.” [Vanity Fair, 8/1/2006] Yet military instructions contradict this, stating, “In the event of a hijacking, the NMCC will be notified by the most expeditious means by the FAA.” [US Department of Defense, 7/31/1997 ; US Department of Defense, 6/1/2001 ]
NORAD Commanders Claim Earlier Awareness of Flight 93 – Two senior NORAD officials will contradict the 9/11 Commission’s conclusion, and claim they were aware of Flight 93 well before it crashed (see Shortly Before 9:36 a.m. September 11, 2001 and (9:36 a.m.-10:06 a.m.) September 11, 2001). [Filson, 2003, pp. 68, 71-73] Colonel Robert Marr, the NEADS battle commander, will tell the Commission that, while the flight was still airborne, “his focus was on UAL 93, which was circling over Chicago,” and he “distinctly remembers watching the flight UAL 93 come west, and turn over Cleveland.” [9/11 Commission, 10/27/2003 ; 9/11 Commission, 1/23/2004 ] Major General Larry Arnold, the commander of the Continental US NORAD Region, will recall, “[W]e watched the [Flight] 93 track as it meandered around the Ohio-Pennsylvania area and started to turn south toward DC.” [Filson, 2003, pp. 71]
10:07 a.m. September 11, 2001: Langley Pilot Reports Aircraft over White House, Asks NEADS for Instructions
One of the pilots that took off from Langley Air Force Base (see (9:25 a.m.-9:30 a.m.) September 11, 2001) calls NORAD’s Northeast Air Defense Sector (NEADS) to relay information he has received about an aircraft over the White House, and is promptly instructed to intercept this aircraft. [Vanity Fair, 8/1/2006]
Borgstrom Wants Instructions – The three F-16s that took off from Langley Air Force Base are now flying in the Baltimore-Washington area. They have just heard a warning over the radio that errant aircraft will be shot down, and received an instruction from the Secret Service to protect the White House (see (10:00 a.m.) September 11, 2001). The FAA’s Washington Center also notified them of a suspicious aircraft flying at high speed toward the White House. In response, pilot Craig Borgstrom radios NEADS and asks weapons director Steve Citino for instructions on what to do. [Spencer, 2008, pp. 222-223] Borgstrom says: “Baltimore [the Washington Center] is saying something about an aircraft over the White House. Any words?” Citino replies: “Negative. Stand by,” and then relays Borgstrom’s message to Major James Fox, the leader of the NEADS weapons team. Fox then notifies Major Kevin Nasypany, the NEADS mission crew commander, of the aircraft over the White House.
Ordered to Intercept – Instinctively, Nasypany responds, “Intercept!” and he then elaborates, “Intercept and divert that aircraft away from there.” Citino passes this instruction to the Langley fighters, telling them their mission is to “intercept aircraft over White House. Use FAA for guidance.” Fox then adds: “Divert the aircraft away from the White House. Intercept and divert it.” Borgstrom confirms the order, saying, “Divert the aircraft.”
Unidentified Aircraft a False Alarm – As the F-16s head for the White House, the NEADS controllers are unable to find the building on their dated equipment, and also have trouble communicating with the Langley pilots. NEADS personnel speculate that the unidentified object is probably just a helicopter or smoke from the burning Pentagon. Minutes later, the suspect aircraft will be realized to probably be one of the Langley fighters, mistakenly reported by a Washington Center air traffic controller who was unaware of the military’s scrambles. Citino will comment: “That was cool. We intercepted our own guys.” [North American Aerospace Defense Command, 9/11/2001; Vanity Fair, 8/1/2006]
10:08 a.m.-10:10 a.m. September 11, 2001: NORAD Commanders Arnold and Marr Consider Possibility of Shootdown Authorization
Two senior NORAD officials, Colonel Robert Marr and Major General Larry Arnold, have to address the possibility of issuing shootdown authorization to fighter jets under their command, after a report is received about an aircraft over the White House. [Spencer, 2008, pp. 224-225]
Aircraft over White House – Marr, the battle commander at NORAD’s Northeast Air Defense Sector (NEADS) in Rome, New York, is in the NEADS battle cab. On the NEADS operations floor, mission crew commander Major Kevin Nasypany has just learned of a report of an aircraft flying over the White House (see 10:07 a.m. September 11, 2001), and now talks to Marr over the phone. Nasypany asks: “Okay, did you hear that? Aircraft over the White House. What’s the word? Intercept and what else?” Marr has a phone to each ear and does not hear what Nasypany says. Nasypany therefore repeats, “Aircraft… over… the White House!” pausing on each word for emphasis. [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 224]
Commanders Discuss Shootdown Order – The news of an aircraft over the White House forces Marr and Arnold, with whom he has been communicating, to address the issue of authorizing the shooting down of aircraft. [Spencer, 2008, pp. 225] Arnold, the commander of NORAD’s Continental US Region (CONR), is at the CONR air operations center at Tyndall Air Force Base in Florida. [Code One Magazine, 1/2002] According to author Lynn Spencer, he has not yet received any instructions from his higher-ups regarding shootdown authorization. “He talked to Major General Rick Findley,” who is at NORAD’s operations center in Colorado, “and asked him to get shootdown authority from the vice president, but he’s still heard nothing back.” [Spencer, 2008, pp. 225]
Arnold Possibly Authorizes Shootdown – Arnold will later tell author Leslie Filson that he has “the authority in case of an emergency to declare a target hostile and shoot it down under an emergency condition.” [Filson, 2003, pp. 75] But according to Vanity Fair, he only passes the current request for rules of engagement further up his chain of command. [Vanity Fair, 8/1/2006] However, Spencer will claim otherwise, stating, “In light of the imminent attack on the White House,” Arnold “decides he will exercise the authority he has to protect the nation in an emergency.” He tells Marr: “We will intercept and attempt to divert. If we can’t, then we’ll shoot it down.” [Spencer, 2008, pp. 225]
Alleged Shootdown Authorization Not Passed On – Minutes later, though, Nasypany will tell his staff that the pilots that took off from Langley Air Force Base (see (9:25 a.m.-9:30 a.m.) September 11, 2001) have “negative clearance to shoot” aircraft over Washington (see 10:10 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 31] And according to the 9/11 Commission, NEADS only learns that NORAD has been given clearance to shoot down threatening aircraft at 10:31 a.m., and even then it does not pass this order along to the fighter pilots under its command (see 10:31 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 42-43]
10:10 a.m. September 11, 2001: NEADS Personnel Told Langley Fighters Cannot Shoot Down Hijacked Planes
The mission crew commander at NORAD’s Northeast Air Defense Sector (NEADS) tells members of his staff that the fighter jets launched from Langley Air Force Base (see (9:25 a.m.-9:30 a.m.) September 11, 2001) have “negative clearance to shoot” aircraft over Washington. [North American Aerospace Defense Command, 9/11/2001; 9/11 Commission, 6/17/2003; Vanity Fair, 8/1/2006; Spencer, 2008, pp. 226-227]
Marr Does Not Pass on Authorization – NEADS battle commander Colonel Robert Marr has just been talking on the phone with Major General Larry Arnold, the commander of NORAD’s Continental US Region, and the two men have discussed whether fighters should be authorized to shoot down hostile aircraft (see (10:08 a.m.-10:10 a.m.) September 11, 2001). According to author Lynn Spencer, Arnold told Marr that if a suspicious aircraft cannot be diverted, “then we’ll shoot it down.” However, this is not the instruction that Marr then passes on to Major Kevin Nasypany, the NEADS mission crew commander. [Spencer, 2008, pp. 225-227] Marr will later tell the 9/11 Commission that at this time, he “may have had the authority” to order a plane shot down, “but he never gave [Nasypany] clearance to fire.” Marr “does not believe at this point there was a clearance to ‘kill.’” [9/11 Commission, 1/23/2004 ]
Order Issued: ‘Negative Clearance to Fire’ – Nasypany relays the instructions Marr gives him to those on the operations floor, saying: “Negative. Negative clearance to shoot.” He then adds: “ID. Type. Tail.” This means the orders are for fighter jets to identify aircraft by their type and tail number, and nothing more. [North American Aerospace Defense Command, 9/11/2001; 9/11 Commission, 8/26/2004, pp. 46-47; Vanity Fair, 8/1/2006] About a minute later, Nasypany’s instructions will be passed to the Langley pilots (see 10:11 a.m. September 11, 2001). [North American Aerospace Defense Command, 9/11/2001; 9/11 Commission, 6/17/2003]
