Major General Larry Arnold, the commander of the 1st Air Force whose mission includes the protection of the continental US against air attacks, tells the Associated Press that he is deeply worried by the possibility of an airborne terrorist attack. He says: “I lie awake worrying. It is one thing to put a truck inside the twin trade towers and blow it up. It is quite another to be able to fly a weapon across our borders. That is an attack, a direct attack, an unambiguous attack from outside our country.” In 1999, a study commissioned by Arnold emphasized the continued importance of the Air Force’s air sovereignty mission and the threat of terrorism (see 1999). [Associated Press, 2/1/2000; Associated Press, 8/2/2002; Filson, 2003, pp. 92] As one of the top commanders of NORAD, Arnold will play a pivotal role on the morning of 9/11 (see (8:42 a.m.) September 11, 2001, (10:08 a.m.-10:10 a.m.) September 11, 2001, and 10:31 a.m. September 11, 2001).

Captain Charles Leidig. 
Captain Charles Leidig. [Source: US Navy]Brigadier General Montague Winfield, the deputy director for operations (DDO) in the National Military Command Center (NMCC) at the Pentagon, leaves his post to attend a pre-scheduled meeting, allowing a colleague, who only recently qualified to take over his position, to stand in for him, and not returning to his post until after the terrorist attacks have ended. [9/11 Commission, 7/21/2003 pdf file; 9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 6/17/2004]
Winfield Attends Air Force-Convened Meeting - Winfield leaves his post to attend what a 9/11 Commission memorandum will call “an unrelated, closed-door personnel meeting convened by the Air Force to discuss the rating of Air Force officers.” [9/11 Commission, 7/21/2003 pdf file] Another Commission memorandum will state that this meeting is a “session for general officers who rated Air Force officers.” It is unclear whether the meeting takes place somewhere in the NMCC or outside the center. The Commission memorandum will only say that it takes place “elsewhere in [Joint Chiefs of Staff] spaces.” At least one of the NMCC’s other qualified DDOs, Brigadier General Norman Seip, is also attending it.
Winfield Asked Colleague to Replace Him on Previous Day - Winfield is temporarily replaced as DDO by Captain Charles Leidig. Leidig only joined the operations directorate of the Joint Chiefs of Staff in July 2001, when he assumed duties as the deputy for Command Center operations. In that, his usual role, he is responsible for the maintenance, operation, and training of watch teams for the NMCC. He qualified to stand in as the DDO in the NMCC about a month ago, in August 2001. The previous afternoon, Winfield asked Leidig to relieve him for a portion of his duty this morning, and Leidig agreed to do so.
Leidig Takes Over as DDO - As arranged, Leidig takes over from Winfield as DDO at 8:30 a.m., allowing Winfield to attend his meeting. Upon arrival at the NMCC, Leidig receives the intelligence and other turn over briefings. After seeing the reports of the plane crashes in New York on television, he will be responsible for convening a significant event conference (see 9:29 a.m.-9:34 a.m. September 11, 2001), which he soon upgrades to an air threat conference (see 9:37 a.m.-9:39 a.m. September 11, 2001). [9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 6/17/2004 pdf file]
Winfield Does Not Resume Duties until Attacks Are Over - Even though it becomes obvious that a coordinated attack is under way when television shows the second plane hitting the World Trade Center at 9:03 a.m. (see 9:03 a.m. September 11, 2001), Winfield apparently remains in his meeting instead of resuming his duties as DDO (see (Shortly After 9:03 a.m.) September 11, 2001). He will only take over from Leidig as DDO after Flight 93 crashes in Pennsylvania, apparently at around 10:30 a.m. (see (10:30 a.m.) September 11, 2001). [9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 6/17/2004] In later interviews for television, Winfield will give the impression that he remained in charge of the NMCC throughout the 9/11 attacks, and make no mention of having allowed a stand-in to take his place during this most critical period of time.

NORAD fails to notify the National Military Command Center (NMCC) at the Pentagon that aircraft have been hijacked before the NMCC initiates a significant event conference in response to the terrorist attacks. [9/11 Commission, 6/9/2004] NORAD’s Northeast Air Defense Sector (NEADS) was alerted to the first hijacking, of Flight 11, at 8:37 a.m. (see (8:37 a.m.) September 11, 2001) and it is alerted to the second hijacking, of Flight 175, at 9:03 a.m. (see (9:03 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20, 23] And yet, according to an after-action report produced by the NMCC, NORAD does not contact the NMCC to alert it to these incidents before the significant event conference commences, at 9:29 a.m. (see 9:29 a.m.-9:34 a.m. September 11, 2001). [9/11 Commission, 6/9/2004]
NORAD Does Not Provide Information to Deputy Director - Captain Charles Leidig, the acting deputy director for operations in the NMCC, will later say that he “does not remember getting a lot of information from NORAD” before the significant event conference begins. [9/11 Commission, 4/29/2004 pdf file] NMCC personnel apparently learn that an aircraft has been hijacked when an officer in the center calls the FAA at 9:00 a.m. (see 9:00 a.m. September 11, 2001). [9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 5/5/2004; 9/11 Commission, 7/24/2004, pp. 35]
NORAD First Mentions a Hijacking at 9:33 a.m. - NORAD will apparently talk to the NMCC about a hijacking for the first time at around 9:33 a.m., when its representative on the significant event conference states that they “concur that [a] hijacked aircraft is still airborne [and] heading towards Washington, DC.” [US Department of Defense, 9/11/2001; US Department of Defense, 9/11/2001 pdf file] (They will presumably be referring to the incorrect information that Flight 11 is still in the air after it has crashed into the World Trade Center (see 9:21 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 26] )
NORAD Does Not Request a Conference - Additionally, according to the NMCC’s after-action report, NORAD “does not request any conference at [National Command Authority] level” prior to the commencement of the significant event conference. [9/11 Commission, 6/9/2004] The significant event conference is actually initiated by Leidig. The NMCC has an important role to play in an emergency like the current crisis. Its job under these circumstances “is to gather the relevant parties and establish the chain of command between the National Command Authority—the president and the secretary of defense—and those who need to carry out their orders,” according to the 9/11 Commission Report. [9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 37] It is also “the focal point within [the] Department of Defense for providing assistance” when there is a hijacking in US airspace, according to a recent military instruction (see June 1, 2001).

Two F-15 fighter jets are scrambled from Otis Air National Guard Base in Cape Cod, Massachusetts, which is 153 miles from New York City. The fighters are launched in response to the hijacked Flight 11, but this plane is already crashing into the World Trade Center at this time (see 8:46 a.m. September 11, 2001). [Washington Post, 9/15/2001; CNN, 9/17/2001; North American Aerospace Defense Command, 9/18/2001; 9/11 Commission, 6/17/2004]
Delay - The FAA’s Boston Center alerted NORAD’s Northeast Air Defense Sector (NEADS) to the hijacking of Flight 11 and requested that fighter jets be scrambled at just before 8:38 a.m. (see (8:37 a.m.) September 11, 2001), but the mission crew commander at NEADS only instructed the leader of his weapons team to launch the Otis fighters at 8:45 a.m. (see 8:45 a.m. September 11, 2001). [Vanity Fair, 8/1/2006]
Otis Aircraft Head to Runway - As soon as the pilots at Otis Air Base are strapped into their aircraft, the green light directing them to launch goes on. They start their engines and taxi out of the hangar to the nearest runway. One of the pilots, Lt. Col. Timothy Duffy, radios his command post for guidance, asking, “Do you have words?” The response he gets is, “Possible hijack, American Flight 11, 737, flight level 290 [29,000 feet], over JFK [International Airport in New York City].” (This flight information is partly incorrect, since American 11 is a 767, not a 737.) According to the Cape Cod Times, the jets will be up in the air before their radar kicks in. [Cape Cod Times, 8/21/2002; Spencer, 2008, pp. 42] The Otis pilots have already been preparing for the scramble order to come since learning of the hijacking from the FAA’s Cape Cod facility, some time shortly after 8:34 a.m. (see (8:36 a.m.-8:41) September 11, 2001). [BBC, 9/1/2002; Spencer, 2008, pp. 27-30] Their jets are reportedly not airborne until seven minutes after being scrambled, at 8:53 a.m. (see 8:53 a.m. September 11, 2001) and there will be conflicting accounts of what their original destination is (see (8:53 a.m.-9:05 a.m.) September 11, 2001).

Those in the National Military Command Center (NMCC) within the Pentagon see the second plane hitting the World Trade Center live on television. According to Dan Mangino, an operations officer at the center, the staff there had thought the first WTC crash was a “terrible accident,” but after seeing the second one, “we knew immediately that it was a terrorist attack.” The American Forces Press Service later reports, “Personnel in the center shifted into hyperdrive.… Phones in the center began ringing off the hook.” Mangino says he initiates “the process to stand up a working group in advance of the direction that would come down later.” One of his deputies is responsible for this process. Yet, despite this supposed urgency, Mangino later recalls that he “knew he would have little time in the days ahead, so he quickly ran to the concourse to get some money out of an automated teller machine.” He will not arrive back at the NMCC until after the Pentagon is hit. [American Forces Press Service, 9/7/2006] Brigadier General Montague Winfield had earlier on allowed a colleague to temporarily take over from him as the NMCC’s deputy director for operations (see 8:30 a.m. September 11, 2001). Yet, despite the obvious emergency now taking place, he does not retake charge of the center until more than an hour later, at around 10:15-10:30 a.m. (see (Shortly After 9:03 a.m.) September 11, 2001). [9/11 Commission, 6/17/2004] Furthermore, according to the 9/11 Commission, the NMCC does not begin a “significant event” conference call in response to the attacks until 9:29 a.m., which is 26 minutes after the South Tower is hit (see 9:29 a.m.-9:34 a.m. September 11, 2001).

Norman Seip.Norman Seip. [Source: US Air Force]A National Operations and Intelligence Watch Officer Network (NOIWON) conference call is established to allow government agencies in the Washington, DC, area to quickly share information regarding the ongoing events, but the call reportedly contributes little of value to the emergency response to the terrorist attacks. [Federal Aviation Administration, 9/11/2001; Federal Aviation Administration, 9/11/2001; 9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 7/13/2004; Government Executive, 6/1/2009] The NOIWON call is convened by the CIA sometime between 9:16 a.m. and 9:25 a.m., according to FAA chronologies. [Federal Aviation Administration, 9/11/2001; Federal Aviation Administration, 9/11/2001; Federal Aviation Administration, 9/17/2001 pdf file] According to an officer at the Pentagon, the White House Situation Room is taking the lead at the time he answers the NOIWON call. [9/11 Commission, 5/5/2004]
FAA Participates in Call - At the FAA headquarters in Washington, the NOIWON call is answered by Bart Merkley, one of two officers on duty in the ACI Watch—a small, 24-hour intelligence facility located on the building’s third floor. [9/11 Commission, 7/13/2004] Merkley stays on the call for its entire duration. He passes onto it information he has learned from the Tactical Net—a teleconference established by the operations center at FAA headquarters at 8:50 a.m. [Federal Aviation Administration, 9/17/2001 pdf file; 9/11 Commission, 5/19/2004]
NMCC Participates in Call - At the National Military Command Center (NMCC) at the Pentagon, the initial call on the NOIWON line is answered by Commander Pat Gardner, the assistant deputy director for operations. [9/11 Commission, 5/5/2004] Subsequently, Brigadier General Norman Seip will take over the line and remain on it for most of the day. According to a 9/11 Commission memorandum, this is because the “White House Situation Room insisted on having a flag officer on an open line” with it. [9/11 Commission, 7/21/2003 pdf file]
NOIWON Call of Little Use - The NOIWON call apparently contributes little of value to the emergency response to the terrorist attacks. Darrel Smith, who is working alongside Merkley in the ACI Watch at FAA headquarters, will tell the 9/11 Commission that he “does not remember any useful or significant information coming as a result of the NOIWON call.” [9/11 Commission, 7/13/2004] Captain Charles Leidig, the acting deputy director for operations in the NMCC throughout the attacks, will tell the Commission that he “recalled no situational awareness that came from the NOIWON call.” [9/11 Commission, 4/29/2004 pdf file] Gardner will say he “doesn’t remember specifically what was discussed” on the call. [9/11 Commission, 5/5/2004] FAA records will state, “It is believed that the [Department of Defense] received information” concerning the attacks over the NOIWON call, but the FAA “holds no records of that communication.” [Federal Aviation Administration, 9/11/2001]
Call Delays Establishing of NMCC's Conference - Furthermore, the NOIWON call delays the Pentagon’s response to the attacks. The NMCC’s usual first action in response to a crisis is to establish a “significant event conference” in order to gather and disseminate information from government agencies, and discuss what actions should be taken. However, the NOIWON call reportedly intervenes with the preparations for such a conference call. According to a 9/11 Commission memorandum, “The NMCC abandoned its attempt to convene a [significant event conference] so its watch officers could participate in the NOIWON conference.” [9/11 Commission, 7/21/2003 pdf file; 9/11 Commission, 6/17/2004] The significant event conference will therefore only commence at 9:29 a.m. (see 9:29 a.m.-9:34 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 37]
No Recording of Call - The NOIWON is described as “a dedicated secure telephone system with a conferencing capability for the rapid exchange and sharing of high interest and time-sensitive information between Washington-area operations centers.” [Government Executive, 6/1/2009] During breaking crises it is used by the major national security watch centers around Washington, including the NMCC and the National Military Joint Intelligence Center at the Pentagon, the State Department Operations Center, the State Department’s Bureau of Intelligence and Research, the CIA’s operations center, the NSA’s operations center, and the White House Situation Room. [Radi, 3/1997 pdf file] The 9/11 Commission will later request a transcript of the NOIWON call conducted on this day, but despite “multiple searches,” no recording of it will be found.

Personnel on the operations floor at NORAD’s Northeast Air Defense Sector (NEADS) confirm to their mission crew commander (MCC) that they are prepared to issue an order to fighter pilots, telling them to fire on a commercial airliner.
MCC Concerned about Possible Shootdown - Major Kevin Nasypany, the NEADS MCC, is concerned about what might happen next as the day’s crisis unfolds. He realizes he may need to order fighter jets under his command to shoot down an errant aircraft. He therefore starts walking up and down the operations floor, impatiently asking all his section heads and weapons technicians, “Are you prepared to follow an order to shoot down a civilian airliner?” All of them affirm that they will issue such an order if required to do so.
Nasypany Confers with Marr - Satisfied with their answers, Nasypany gets on the phone to Colonel Robert Marr, who is in the NEADS battle cab, and asks him, “Have we already asked the questions?” What Nasypany means is, have they asked about getting authorization to take out a threatening aircraft? According to author Lynn Spencer, “Those authorizations, [Nasypany] knows, are going to have to come from the president himself, passed down from senior NORAD command in Colorado Springs.” Marr replies that Major General Larry Arnold, who is at the Continental US NORAD Region (CONR) headquarters in Florida, is seeking the necessary authorizations and is prepared to take any action required. Nasypany then briefs Marr on the armaments on board the fighters NEADS has had launched (see 8:46 a.m. September 11, 2001). He adds: “My recommendation, if we have to take anybody out, large aircraft, we use AIM-9s in the face. If need be.” He means that if there is another hijacking, the most effective way to bring the plane down would be to fire a missile into its nose. [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 140-141]
Pilots Do Not Receive Shootdown Authorization - At around 9:35 a.m., according to Spencer, a NEADS weapons controller will ask one of the pilots that launched in response to the first hijacking whether he would be willing to shoot down a hijacked aircraft (see (9:35 a.m.) September 11, 2001). [Spencer, 2008, pp. 153] According to the 9/11 Commission, however, NEADS personnel will only learn that NORAD has been cleared to shoot down threatening aircraft at 10:31 a.m., and even then they will not pass this order along to the fighter pilots (see 10:31 a.m. September 11, 2001).

According to the 9/11 Commission, NEADS is contacted by the FAA’s Boston Center. Colin Scoggins, Boston Center’s military liaison, tells it: “I just had a report that American 11 is still in the air, and it’s on its way towards—heading towards Washington.… That was another—it was evidently another aircraft that hit the tower. That’s the latest report we have.… I’m going to try to confirm an ID for you, but I would assume he’s somewhere over, uh, either New Jersey or somewhere further south.” The NEADS official asks: “He—American 11 is a hijack?… And he’s heading into Washington?” Scoggins answers yes both times and adds, “This could be a third aircraft.” Somehow Boston Center has been told by FAA headquarters that Flight 11 is still airborne, but the 9/11 Commission will say it hasn’t been able to find where this mistaken information came from.
Scoggins Makes Error - Vanity Fair magazine will later add, “In Boston, it is Colin Scoggins who has made the mistaken call.” Scoggins will explain why he believes he made this error: “With American Airlines, we could never confirm if [Flight 11] was down or not, so that left doubt in our minds.” He says he was monitoring a conference call between FAA centers (see 8:28 a.m. September 11, 2001), “when the word came across—from whom or where isn’t clear—that American 11 was thought to be headed for Washington.” However, Boston Center was never tracking Flight 11 on radar after losing sight of it near Manhattan: “The plane’s course, had it continued south past New York in the direction it was flying before it dipped below radar coverage, would have had it headed on a straight course toward DC. This was all controllers were going on.” Scoggins says, “After talking to a supervisor, I made the call and said [American 11] is still in the air.” [Northeast Air Defense Sector, 9/11/2001; 9/11 Commission, 6/17/2004; Vanity Fair, 8/1/2006]
Myers Refers to Mistaken Report - In the hours following the attacks, acting Chairman of the Joint Chiefs of Staff Richard Myers will apparently refer to this erroneous report that Flight 11 is still airborne and heading toward Washington, telling the Associated Press that “prior to the crash into the Pentagon, military officials had been notified that another hijacked plane had been heading from the New York area to Washington.” Myers will say “he assumed that hijacked plane was the one that hit the Pentagon, though he couldn’t be sure.” [Associated Press, 9/11/2001]

The National Miilitary Command Center, inside the Pentagon.The National Miilitary Command Center, inside the Pentagon. [Source: US Department of Defense]The National Military Command Center (NMCC) at the Pentagon finally commences and runs a “significant event conference” in response to the ongoing crisis, 26 minutes after the second plane hit the World Trade Center and officers in the NMCC realized the US was under terrorist attack. [9/11 Commission, 6/17/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 37; American Forces Press Service, 9/7/2006]
NMCC Directors Decided to Establish Conference - After those in the NMCC saw Flight 175 hitting the WTC live on television at 9:03 a.m. (see 9:03 a.m. September 11, 2001), Captain Charles Leidig, the acting deputy director for operations (DDO) in the center throughout the attacks, and Commander Pat Gardner, the assistant DDO, talked about the need to convene a significant event conference so there could be a discussion of what actions were to be taken in response. The DDO and the assistant DDO are the two officers responsible for deciding what type of conference the NMCC should convene, and when it should do so. Because there is no specific procedure for dealing with terrorist attacks, Leidig and Gardner decided a significant event conference would most suit their needs, because it would have the flexibility of allowing more people to be added in as required. They also discussed who would need to be on this conference. [9/11 Commission, 4/29/2004 pdf file] But Major Charles Chambers, who is currently on duty in the NMCC, will give a slightly different account. According to Chambers, Staff Sergeant Val Harrison had a phone in her hand and said NORAD was asking for a significant event conference. Leidig had agreed, and so Harrison started establishing the conference.
Conference Begins with Recap of Situation - According to Chambers, “The computer does a mass dialing to connect to those command centers that are always included” in an NMCC conference call, but Harrison also had to manually call the civilian agencies that were going to be included in the conference, such as the FAA, the FBI, and the Federal Emergency Management Agency (FEMA). [US Department of Defense, 9/2001] The conference then begins at 9:29 a.m. with a brief recap: Two aircraft have hit the WTC, there is a confirmed hijacking of Flight 11, and fighter jets have been scrambled from Otis Air National Guard Base in Massachusetts (see 8:46 a.m. September 11, 2001). The FAA is asked to provide an update, but its line is silent as the agency has not yet been added to the call (see (9:29 a.m.-12:00 p.m.) September 11, 2001). A minute later, Leidig states that it has just been confirmed that Flight 11 is still airborne and is heading toward Washington, DC. (This incorrect information apparently arose minutes earlier during a conference call between FAA centers (see 9:21 a.m. September 11, 2001).) [9/11 Commission, 7/24/2004, pp. 37] NMCC conference calls are moderated by the DDO. [9/11 Commission, 7/21/2003 pdf file] Leidig will tell the 9/11 Commission that they are conducted over “a special phone circuit, and it’s classified to be able to pass information, relay information between very senior leadership all the way over to the White House.” [9/11 Commission, 6/17/2004]
NMCC Struggled to Convene Conference - Some officers currently on duty in the NMCC will later complain about circumstances that delayed the establishing of the significant event conference. Chambers will recall that the conference took “much longer than expected to bring up.” [US Department of Defense, 9/2001] Gardner will tell the 9/11 Commission that the NMCC had been “struggling to build the conference,” which “didn’t get off as quickly as hoped.” [9/11 Commission, 5/5/2004] He will describe his “frustration that it wasn’t brought up more quickly.” [9/11 Commission, 5/12/2004]
Other Conference and Connection Problems Delayed Call - Preparations for the conference were disrupted as a result of the CIA convening a National Operations and Intelligence Watch Officer Network (NOIWON) conference call between government agencies in the Washington area, reportedly at sometime between 9:16 a.m. and 9:25 a.m. (see (Between 9:16 a.m. and 9:25 a.m.) September 11, 2001). According to a 9/11 Commission memorandum, the NMCC had “abandoned its attempt to convene a [significant event conference] so its watch officers could participate in the NOIWON conference.” [Federal Aviation Administration, 9/11/2001; Federal Aviation Administration, 9/11/2001; 9/11 Commission, 7/21/2003 pdf file] Another factor that slowed attempts to convene the significant event conference was a problem with connecting some agencies to it. According to Chambers, “A couple of the civil agencies couldn’t be reached and others kept dropping off moments after connecting.” He will recall, “We finally decided to proceed without those agencies that were having phone problems.” [US Department of Defense, 9/2001] Leidig had announced that the NMCC would have to start without those agencies and add them to the conference later on. [9/11 Commission, 5/12/2004]
Call Ends after Five Minutes - The significant event conference ends after only a few minutes, following a recommendation by NORAD that it be reconvened as an “air threat conference.” It is brought to an end at around 9:34 a.m., and will resume as an air threat conference at 9:37 a.m. (see 9:37 a.m.-9:39 a.m. September 11, 2001).

Counterterrorism “tsar” Richard Clarke, who is in the White House Situation Room, requests a fighter escort for Air Force One and authorization for the Air Force to shoot down threatening aircraft. According to Clarke’s own account, when they see President Bush starting his short speech from the Booker Elementary School library on television (at about 9:30), he and others in the Situation Room briefly discuss getting the president away from the school to somewhere safer. Clarke then telephones the Presidential Emergency Operations Center (PEOC) below the White House, which contains Vice President Dick Cheney and others. He speaks with Army Major Mike Fenzel and instructs him: “Mike, somebody has to tell the president he can’t come right back here [to Washington]. Cheney, Condi, somebody. Secret Service concurs. We do not want them saying where they are going when they take off. Second, when they take off, they should have fighter escort. Three, we need to authorize the Air Force to shoot down any aircraft—including a hijacked passenger flight—that looks like it is threatening to attack and cause large-scale death on the ground. Got it?” Fenzel replies, “Roger that, Dick, get right back to you.” This conversation appears to take place shortly before the Pentagon attack occurs, so roughly around 9:35 or 9:36, as soon afterwards Secret Service Director Brian Stafford slips Clarke a note stating that radar shows an aircraft heading their way (see (9:37 a.m.) September 11, 2001), and then Ralph Seigler, the Situation Room deputy director, reports an explosion having occurred at the Pentagon. [Clarke, 2004, pp. 6-7] However, it is unclear how long it takes for Clarke’s requests to be implemented. According to some accounts, fighters do not arrive to accompany Air Force One until an hour or more after it takes off (see (11:29 a.m.) September 11, 2001). Reports are also contradictory as to when shootdown authorization is given for the Air Force. According to Clarke’s own recollections, it is given between around 9:38 and 9:56 (see (9:38 a.m.) September 11, 2001 and (Between 9:45 a.m. and 9:56 a.m.) September 11, 2001). Other accounts, including that of the 9/11 Commission, state that it is not given until after 9:56, possibly as late as 10:20 (see (Shortly After 9:56 a.m.) September 11, 2001 and 10:18 a.m.-10:20 a.m. September 11, 2001).

In the middle of the 9/11 attacks, General Ralph Eberhart, the commander of NORAD, drives from his NORAD headquarters office at Peterson Air Force Base, Colorado to the NORAD operations center in Cheyenne Mountain, about a dozen miles away. The journey reportedly takes him 45 minutes and en route he loses a cell phone call with Vice President Cheney. The reason he makes this journey is unknown, though it is reported that there are superior communications capabilities available at Cheyenne Mountain. [Colorado Springs Gazette, 6/16/2006; Denver Post, 7/28/2006; Washington Post, 7/29/2006] The exact times when Eberhart departs Peterson AFB and arrives at Cheyenne Mountain are unclear. General Richard Myers says that Eberhart phones him from Peterson either just before or just after the Pentagon is hit, which suggests that Eberhart heads out some time between 9:35 a.m. and 9:40 a.m. [Armed Forces Radio And Television Service, 10/17/2001; 9/11 Commission, 6/17/2004] Eberhart tells the 9/11 Commission that when he arrives at the NORAD operations center, the order to shoot down hijacked aircraft has already been passed down NORAD’s chain of command. According to the commission’s timeline, this would indicate he arrives after 10:31 a.m. (see 10:31 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 42] Yet other reports state that the massive blast doors to Cheyenne Mountain are shut at around 10:15 a.m. (see (10:15 a.m.) September 11, 2001), which suggests that Eberhart arrives earlier.

Dan Shanower.Dan Shanower. [Source: Family photo / Associated Press]Petty Officer Jason Lhuillier is on duty at the Chief of Naval Operations Intelligence Plot (CNO-IP). This small intelligence unit is located within the Navy Command Center at the Pentagon, on the first floor of the building’s southwest face. Since learning of the second plane hitting the WTC, he and his colleagues have been trying to build the intelligence picture, liaising with such agencies as the CIA and the Defense Intelligence Agency. Shortly before the Pentagon is struck, Lhuillier receives a phone call from the National Military Joint Intelligence Center (NMJIC). [Washington Post, 9/16/2001; Washington Post, 1/20/2002; Daily Telegraph, 9/11/2002] Like the National Military Command Center (NMCC), the NMJIC is located in the Joint Staff area of the Pentagon. It constantly monitors worldwide developments for any looming crises that might require US involvement. [Washington Times, 9/25/1997; Joint Chiefs of Staff, 2/6/2006] The caller informs Lhuillier, “We’ve got indications of another aircraft that’s been hijacked. It’s heading out to DC.” [Daily Telegraph, 9/11/2002] The caller may possibly be referring to the same incorrect report that was received by the NMCC at around 9:30 a.m., that Flight 11 is still airborne and heading toward Washington (see 9:29 a.m.-9:34 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 37] Lhuillier then interrupts a meeting between Commander Dan Shanower, who is in charge of the CNO-IP, and six others, to tell them about this third plane. Commander David Radi, an aide to Admiral William Fallon, the vice chief of naval operations, is in his Pentagon office about 100 yards from the CNO-IP. He has also heard fragmentary reports about another hijacked plane heading towards Washington, and that fighter jets are being scrambled. He calls the CNO-IP for more information, but is only told, “We’re working on it.” Radi later recalls that he’d wondered where the plane might be heading: “I’m thinking to myself, ‘Well, the Pentagon, the White House or the Capitol.’” Within minutes, the Pentagon is struck. The CNO-IP will be destroyed in the impact, and seven people working in it will be killed. [Washington Post, 1/20/2002; Arlington County Police Department, 2/21/2002; Daily Telegraph, 9/11/2002]

The National Military Command Center (NMCC) at the Pentagon commences an “air threat conference” at 9:37 a.m. in response to the terrorist attacks, which will last for more than eight hours and have numerous high-level government and military officials participating at various times.
NORAD Reports Two More Hijackings - Captain Charles Leidig opens the call at 9:39 a.m. [9/11 Commission, 7/24/2004, pp. 37-38] As the acting deputy director for operations (DDO) in the NMCC during the attacks, Leidig is responsible for moderating the air threat conference and generating a military response to the crisis. [9/11 Commission, 4/29/2004 pdf file] He begins the call saying: “An air attack against North America may be in progress. NORAD, what’s the situation?” NORAD says it has conflicting reports, and its latest information is of “a possible hijacked aircraft taking off out of JFK [International Airport in New York], en route to Washington, DC.” [9/11 Commission, 7/24/2004, pp. 38] NORAD says the FAA has also passed it information about a second additional hijacking. Major Charles Chambers, who is currently on duty in the NMCC, will later recall, “This was probably a communications mix-up, but we all thought for a while that there were a total of five hijackings.” [US Department of Defense, 9/2001]
NMCC Reports Pentagon Attack - The NMCC reports that there has been a crash into the mall side of the Pentagon and requests that the secretary of defense be added to the conference. (However, despite being in the Pentagon when it is hit, Defense Secretary Donald Rumsfeld will not enter the NMCC and join the air threat conference until around 10:30 a.m. (see (10:30 a.m.) September 11, 2001).) [9/11 Commission, 7/24/2004, pp. 38] The air threat conference is broadcast over a loudspeaker inside the NMCC. [US News and World Report, 8/31/2003] According to Chambers, “Questions were flying left and right on the conference, and trying to keep things straight was very difficult.” [US Department of Defense, 9/2001]
NORAD Recommended Air Threat Conference - Leidig and Commander Pat Gardner, the assistant DDO, had earlier on decided to convene an all-purpose “significant event conference” in response to the attacks on the World Trade Center. That call commenced at 9:29 a.m. (see 9:29 a.m.-9:34 a.m. September 11, 2001). NORAD had recommended that it be reconvened as an air threat conference. [9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 37] According to Chambers, an air threat conference is used when aircraft are considered to be hostile and involves many more people than are in a significant event conference, including the chairman of the Joint Chiefs of Staff, the secretary of defense, and officials from the White House. [US Department of Defense, 9/2001] However, Leidig thought a significant event conference was the correct kind of call for the situation. He will tell the 9/11 Commission that an air threat conference “had Cold War implications and brought a different group of people to a conference.” [9/11 Commission, 4/29/2004 pdf file] Gardner will say that threat conferences are intended for dealing with external threats. [9/11 Commission, 5/12/2004]
Deputy Director Ordered Upgrading of Conference - All the same, Leidig gave the order to transition to an air threat conference. [9/11 Commission, 7/24/2004, pp. 37] He will tell the 9/11 Commission that, in retrospect, the reason he thinks he did so “was because he perceived an air threat at that time.” [9/11 Commission, 4/29/2004 pdf file] Therefore, the significant event conference was brought to an end at around 9:34 a.m., and resumes as an air threat conference three minutes later. [9/11 Commission, 7/24/2004, pp. 37] Staff Sergeant Val Harrison could have established the air threat conference either by leaving all of those participating in the significant event conference on the line and then adding new participants one at a time, or by simply hanging up on everyone in the significant event conference and then having the computer do a mass dialing. Harrison recommended the second option. Leidig had agreed, and directed her to disconnect the conference call and start over.
Problem with Connecting Some Agencies - As happened with the significant event conference, there are problems connecting several agencies to the air threat conference. [US Department of Defense, 9/2001] Despite repeated attempts, operators struggle to get the FAA connected (see (9:29 a.m.-12:00 p.m.) September 11, 2001), and it will take until 10:17 a.m. for an FAA representative to finally join the call (see 10:17 a.m. September 11, 2001). [9/11 Commission, 7/21/2003 pdf file; 9/11 Commission, 7/24/2004, pp. 37] Other agencies had not understood what Leidig meant about convening the new conference, and so did not hang up their phones when the NMCC disconnected the previous conference call. As a result, all the NMCC got from them was a busy signal over the line. Chambers will recall, “As with the [significant event conference], it took longer than expected to convene the [air threat conference].” [US Department of Defense, 9/2001]
Top Officials Participate - Throughout the more than eight hours the air threat conference is running for, numerous key officials will participate in it at various times, including President Bush, Vice President Dick Cheney, Deputy National Security Adviser Stephen Hadley, acting Chairman of the Joint Chiefs of Staff Richard Myers, military personnel from the Presidential Emergency Operations Center below the White House, and the president’s military aide on Air Force One. [9/11 Commission, 7/24/2004, pp. 37] Brigadier General Montague Winfield, the original DDO, who had Leidig take his place so he could attend a pre-scheduled meeting (see 8:30 a.m. September 11, 2001), will later recall, “All of the governmental agencies… that were involved in any activity that was going on in the United States… were in that conference.” [ABC News, 9/11/2002]
Winfield Runs Conference after Returning to Post - Winfield will take over the running of the air threat conference from Leidig after returning to his post at around 10:30 a.m. (see (10:30 a.m.) September 11, 2001). [CNN, 9/4/2002; 9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 6/17/2004] But although NMCC conference calls are moderated by the DDO, Rumsfeld will use the DDO’s phone to participate in the air threat conference, meaning that Winfield is unable to moderate the conference when the defense secretary is participating.

According to one account, counterterrorism “tsar” Richard Clarke is given the go-ahead to authorize Air Force jets to shoot down threatening aircraft around this time. In late 2003, Clarke will recall to ABC News that, minutes earlier, he’d picked up the phone in the White House Situation Room and called Vice President Dick Cheney, who is in the Presidential Emergency Operations Center (PEOC) below the White House. He’d told him: “We have fighters aloft now. We need authority to shoot down hostile aircraft.” [ABC News, 11/29/2003] This call appears to be one Clarke also describes in his 2004 book Against all Enemies, though in that account he will describe having made his request to Army Major Mike Fenzel, who is also in the PEOC, rather than directly to Cheney. According to that account, the call occurred shortly before Clarke learns of the Pentagon attack, so roughly around 9:36 (see (Between 9:30 a.m. and 9:37 a.m.) September 11, 2001). [Clarke, 2004, pp. 6-7] Clarke describes to ABC News, “I thought that would take forever to get that [shootdown] authority.” But, “The vice president got on the phone to the president, got back to me, I would say within two minutes, and said, ‘Do it.’” [ABC News, 11/29/2003] If correct, this would mean the president authorizes military fighters to shoot down threatening aircraft at around 9:37-9:38. However, around this time, the president and vice president are reportedly having difficulty communicating with each other, while Bush heads from the Booker Elementary School to the Sarasota airport (see (9:34 a.m.-9:43 a.m.) September 11, 2001). [New York Times, 6/18/2004; Canadian Broadcasting Corporation, 9/10/2006] Furthermore, this account contradicts several others. In his 2004 book, Clarke will describe being told to inform the Pentagon it has shootdown authorization slightly later, some time between 9:45 and 9:56 (see (Between 9:45 a.m. and 9:56 a.m.) September 11, 2001). [Clarke, 2004, pp. 8] According to journalists Bob Woodward and Bill Sammon, Bush gives the shootdown authorization in a phone call with Cheney shortly after 9:56 (see (Shortly After 9:56 a.m.) September 11, 2001). [Sammon, 2002, pp. 102; Woodward, 2002, pp. 17-18; Washington Post, 1/27/2002] The 9/11 Commission will say he gives it in a call at 10:18 (see 10:18 a.m.-10:20 a.m. September 11, 2001).

According to his own account, counterterrorism “tsar” Richard Clarke is informed that President Bush has authorized the military to shoot down threatening aircraft. Clarke had requested that this authorization be given at around 9:36 (see (Between 9:30 a.m. and 9:37 a.m.) September 11, 2001). In his 2004 book Against all Enemies he will state that he receives a response shortly after the time people begin rapidly evacuating from the White House, and while Air Force One is getting ready to take off. This would therefore be sometime between 9:45 and 9:56. He gets a phone call from the Presidential Emergency Operations Center (PEOC) below the White House, where Vice President Dick Cheney and National Security Adviser Condoleezza Rice are located. On the other end is Army Major Mike Fenzel. Fenzel tells Clarke: “Air Force One is getting ready to take off, with some press still on board. He’ll divert to an air base. Fighter escort is authorized. And… tell the Pentagon they have authority from the president to shoot down hostile aircraft, repeat, they have authority to shoot down hostile aircraft.” Clarke replies, “Roger that.” In his recollection of this call, Clarke comments, “I was amazed at the speed of the decisions coming from Cheney and, through him, from Bush.” Clarke then gets the attention of those on the video conference screen for the Pentagon, and informs them, “the president has ordered the use of force against aircraft deemed to be hostile.” [CNN, 9/12/2001; Clarke, 2004, pp. 7-8] This description contradicts several other accounts of when the president gives the shootdown authorization. In late 2003, Clarke tells ABC News he gets the go-ahead from the vice president “within two minutes” after he requested shootdown authorization, meaning therefore around 9:37-9:38 (see (9:38 a.m.) September 11, 2001). [ABC News, 11/29/2003] Some accounts say that Bush gives the authorization later, at shortly after 9:56 (see (Shortly After 9:56 a.m.) September 11, 2001). [Sammon, 2002, pp. 102; Washington Post, 1/27/2002] According to the 9/11 Commission, it is not given until around 10:18 (see 10:18 a.m.-10:20 a.m. September 11, 2001).

An air traffic controller at the FAA’s Cleveland Center enters a new flight plan for Flight 93 into the FAA computer system, giving a new destination of Reagan National Airport in Washington, DC. Flight 93 is currently flying in the airspace covered by the Cleveland Center’s Imperial Sector radar position, which is being managed by controller Linda Justice. [Federal Aviation Administration, 9/11/2001; St. Petersburg Times, 9/12/2001; 9/11 Commission, 10/2/2003 pdf file; Lynn Spencer, 2008]
Controller Enters New Flight Plan for Flight 93 - Justice changes the flight’s destination code from “SFO,” the code for San Francisco International Airport, to “DCA,” the code for Ronald Reagan Washington National Airport. [St. Petersburg Times, 9/12/2001] An FAA chronology will specify that she changes the flight plan “direct HGR [the code for Hagerstown Regional Airport in Maryland] to DCA.” [Federal Aviation Administration, 9/11/2001] Another FAA chronology will similarly state that Justice reroutes Flight 93 “direct to Hagerstown direct to Washington National.” [Federal Aviation Administration, 12/6/2001] Flight 93’s tag therefore now reads, “Hagerstown—National,” according to Justice. [9/11 Commission, 10/2/2003 pdf file]
New Flight Plan Not Due to Communication with Pilot - The reason Justice enters a new flight plan for Flight 93 is unclear. A minute earlier, the hijacker pilot on Flight 93 reprogrammed the plane’s navigational system for the new destination of Reagan Airport (see 9:55 a.m. September 11, 2001). [Longman, 2002, pp. 182; 9/11 Commission, 7/24/2004, pp. 457] And according to the St. Petersburg Times, controllers typically only change a plane’s destination when this is requested by the pilots. [St. Petersburg Times, 9/12/2001] But one of the FAA chronologies will state that Justice’s change to the flight plan is “not a result of any communication with the pilot.” [Federal Aviation Administration, 9/11/2001]
Flight Plan Changed to Aid Handoff to Washington Controllers - Justice will later explain why she changes the flight plan. She will state that Flight 93 appears to be heading toward the airspace of the FAA’s Washington Center, and so, in “an attempt to expedite the situation,” she enters the change of routing to reflect Hagerstown Airport to Reagan Airport. She will say she does this “only to forward [the] information [about Flight 93] to the sectors the aircraft appeared to be tracking toward.” [Federal Aviation Administration, 9/12/2001 pdf file] Justice will tell the 9/11 Commission that she changes the routing when she sees Flight 93 is heading eastbound. She will say, “The easiest way to do a handoff is to change the flight plan,” and also say she changes the flight plan “to show that Washington Center was the recipient.” According to Justice, the “controversial step” she takes is “putting in Hagerstown, because the misconception was that she had communicated with the plane and cleared it through.” [9/11 Commission, 10/2/2003 pdf file] John Werth, another controller at the Cleveland Center, will tell the 9/11 Commission that Justice enters the new destination for Flight 93 “because she knew it would be easier to track the primary [radar track for the aircraft] when the computer has a flight plan to work with.” [9/11 Commission, 10/1/2003 pdf file] After changing the flight plan, Justice calls the Potomac Sector radar position at the Washington Center and tells the controller there to “pull up the data block” for Flight 93. Justice will say it is clear to the Washington Center controller that she has created the new destination in order to make it easier to locate the plane. [Federal Aviation Administration, 9/12/2001 pdf file; 9/11 Commission, 10/2/2003 pdf file]
New Flight Plan Causes False Reports of Plane Approaching Washington - According to author Lynn Spencer, the new flight plan creates a “coast track” of Flight 93 on the traffic situation displays at air traffic control facilities. “A coast track,” Spencer will write, “differs from a radar track in that it is not supported by radar returns but rather by a computer-generated, projected course for the flight. Although this track did not appear on controller radar screens, its presence on their [traffic situation displays] allowed Washington controllers to monitor the flight’s progression toward Washington.” According to Spencer, the presence of this coast track leads to incorrect reports of an aircraft approaching Washington in the minutes after Flight 93 crashes. She will write, “A controller in Washington, unaware that the flight had crashed, was calling position reports for the coast track of United 93 to the White House (see (Between 10:10 a.m. and 10:15 a.m.) September 11, 2001)… as well as the FBI at the Pentagon (where firefighters were evacuated and the firefight suspended in anticipation of a second impact)” (see (10:15 a.m.-10:38 a.m.) September 11, 2001).

President Bush talks on the phone to Vice President Dick Cheney. Cheney recommends that Bush authorize the military to shoot down any plane that might be under the control of hijackers. “I said, ‘You bet,’” Bush later recalls. “We had a little discussion, but not much.” [USA Today, 9/16/2001; Newsday, 9/23/2001; Washington Post, 1/27/2002; CBS News, 9/2/2003] Bush recalls that this isn’t a difficult decision for him to make, “once I realized there was a protocol… because again, I now realized we’re under attack. This is a war.” According to journalists Bob Woodward and Bill Sammon, this call between Bush and Cheney takes place shortly after 9:56, when Air Force One took off from the Sarasota airport. [Sammon, 2002, pp. 102; Woodward, 2002, pp. 17-18; Washington Post, 1/27/2002] Consistent with this, Bush and Cheney will tell the 9/11 Commission that Bush gives the shootdown authorization during a call estimated to occur between about 10:00 and 10:15 (see (Between 10:00 a.m. and 10:15 a.m.) September 11, 2001). But the 9/11 Commission will say the authorization is given in a later call, at 10:18 (see 10:18 a.m.-10:20 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 40-41] Bush later indicates that he doesn’t make any major decisions about how to respond to the attacks until after boarding Air Force One, which fits with these accounts of him approving shootdown authorization after take off. [White House, 12/4/2001; Wall Street Journal, 3/22/2004 pdf file] But according to counterterrorism “tsar” Richard Clarke, the authorization is given earlier, at some point between about 9:38 and 9:56 (see (9:38 a.m.) September 11, 2001 and (Between 9:45 a.m. and 9:56 a.m.) September 11, 2001).

[Source: David Bohrer / White House] (click image to enlarge)According to the 9/11 Commission, Vice President Dick Cheney is told that the Air Force is trying to establish a combat air patrol (CAP) over Washington. Cheney, who is in the Presidential Emergency Operations Center (PEOC) below the White House, then calls President Bush on Air Force One to discuss the rules of engagement for this CAP. Cheney later tells the 9/11 Commission that he’d felt “it did no good to establish the CAP unless the pilots had instructions on whether they were authorized to shoot if the plane would not divert.” He recalls that “the president signed off on that concept.” Bush will recall this phone call and emphasize to the 9/11 Commission that, during it, he had authorized the shootdown of hijacked aircraft. National Security Adviser Condoleezza Rice, who is in the PEOC with Cheney, will tell the Commission she recalls hearing Cheney inform the president: “Sir, the CAPs are up. Sir, they’re going to want to know what to do.” Then she hears Cheney say, “Yes sir.” However, as the Commission will later note, “Among the sources that reflect other important events that morning there is no documentary evidence for this call, although the relevant sources are incomplete” (see (Mid 2004)). [9/11 Commission, 7/24/2004, pp. 40-41] Reportedly, some members of the Commission’s staff will not believe this call between Bush and Cheney ever took place. [Newsweek, 6/20/2004] Cheney phones Bush at 10:18 (see 10:18 a.m.-10:20 a.m. September 11, 2001). According to the 9/11 Commission, it is in fact during that call that Bush authorizes the military to shoot down threatening aircraft. [9/11 Commission, 7/24/2004, pp. 41]

General Henry Shelton, the chairman of the Joint Chiefs of Staff, talks over the phone with General Richard Myers, the vice chairman of the Joint Chiefs of Staff, who is at the Pentagon, and is given information about the Pentagon attack and the military’s response to the terrorist attacks. Shelton took off at 7:15 a.m. to fly to Europe for a NATO conference (see 7:15 a.m. September 11, 2001). He learned of the attacks in New York while his plane was over the Atlantic Ocean, and has just been told of a “big explosion at the Pentagon” (see (8:50 a.m.-10:00 a.m.) September 11, 2001).
First Report Is of a Hand Grenade Going Off at Pentagon - Shelton heads to the communications console just behind the plane’s cockpit. From there, he talks over a secure, encrypted phone line with Myers, who is in the National Military Command Center (NMCC) at the Pentagon. Myers updates Shelton on what is known about the explosion at the Pentagon. He says the first report is that a hand grenade went off in the Pentagon parking lot.
Myers Updates Shelton on Military Response to Attacks - Myers then gives Shelton a complete status report. He says: “We’ve transitioned the SIEC [significant event conference] into an air threat conference call, which is in progress as we speak (see 9:29 a.m.-9:34 a.m. September 11, 2001 and 9:37 a.m.-9:39 a.m. September 11, 2001). FAA has requested that NORAD take over control of US airspace. Fighters have scrambled to escort Air Force One (see (After 9:56 a.m.) September 11, 2001) and we’re sending AWACS up to provide further monitoring (see Before 9:55 a.m. September 11, 2001). We’ve escalated to Threatcon Delta and are about to launch the NAOC [National Airborne Operations Center plane]. Bases around the world are locked tight, [Deputy Secretary of Defense Paul] Wolfowitz has been relocated to Site R (see (11:00 a.m.) September 11, 2001), plus, [Deputy National Security Adviser Stephen] Hadley has requested we implement full ‘Continuity of Government measures’ (see 9:59 a.m. September 11, 2001), and we are proceeding along those lines.”
Myers Says Plane Hit the Pentagon - Myers is then interrupted by some commotion in the background. When he returns to the line, he tells Shelton, “Okay, we just got the word: the prior report was incorrect; it was not a hand grenade that exploded, it was another commercial airline that struck the Pentagon.” He then continues with his status report, saying, “[P]er the president, we’ve gone weapons free in the event of a hijacked aircraft or one that threatens the White House.” [Giesemann, 2008, pp. 20, 22-24; Shelton, Levinson, and McConnell, 2010, pp. 430-433]
Shelton Wants to Return to Washington - Myers will tell the 9/11 Commission that after he arrives at the NMCC—presumably referring to the time of this phone call—he “recommended General Shelton return to Washington, DC.” [9/11 Commission, 6/17/2004 pdf file] But Shelton will recall that he tells Myers, “I need you to call Ed Eberhart [General Ralph Eberhart, the commander of NORAD] at NORAD and let him know that we’re coming back [to Washington] on Speckled Trout [the nickname of the plane he is on], and tell him that I would consider it a personal favor if he would see to it that the chairman and his crew are not shot down on their way back to Andrews.” Myers confirms, “Will do.” According to Shelton, his plane is called back 10 minutes later “with confirmation that we had been officially cleared to fly through the shutdown airspace.” [Shelton, Levinson, and McConnell, 2010, pp. 433] But according to Captain Rob Pedersen, the flight navigator on Shelton’s plane, it is several hours before the plane is cleared to enter the US airspace (see (After 9:45 a.m.) September 11, 2001). [Air Force Magazine, 9/2011 pdf file] The plane will therefore only land at Andrews Air Force Base, near Washington, at 4:40 p.m. (see 4:40 p.m. September 11, 2001) and Shelton will only arrive at the NMCC an hour after that (see 5:40 p.m. September 11, 2001). [Federal Aviation Administration, 9/11/2001 pdf file; Myers, 2009, pp. 159] The exact time of the call between Shelton and Myers is unclear, though it would be at some time after about 10:00 a.m., when Myers arrives at the NMCC (see (Between 9:55 a.m. and 10:25 a.m.) September 11, 2001).

The air traffic control tower at Andrews Air Force Base, near Washington, DC, broadcasts regular warnings over radio that any aircraft entering the restricted airspace around the capital will be shot down, even though, according to the 9/11 Commission, the president does not authorize the shooting down of threatening aircraft until 10:18 a.m. [9/11 Commission, 2004; 9/11 Commission, 2/17/2004; 9/11 Commission, 3/11/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 41] The Andrews control tower begins broadcasting warning messages over the Air Traffic Information System (ATIS) at 10:05 a.m. [9/11 Commission, 3/11/2004 pdf file] The ATIS is an automatic information system over which “[p]re-recorded airfield advisory information is automatically transmitted at timed intervals over the airways on a specific frequency.” [US Air Force, 10/1/1999 pdf file]
Planes Told They Could Be 'Shot Down' - A 9/11 Commission document summarizing key transmissions from the Andrews tower will show that warning messages are broadcast about once or twice every 10 minutes. The messages, which are all quite similar, include: “No fly notice. Remain clear of Andrews Class B airspace or you will be shot down,” and, “Any aircraft monitoring Andrews Approach Control frequency: remain clear of Andrews Class B airspace or you will be shot down.” [9/11 Commission, 2/17/2004] (Class B airspace is restricted airspace in which no one is supposed to fly without a working transponder and permission from an air traffic controller. The airspace around much of Washington is designated Class B airspace. [Washington Post, 9/12/2001; New York Times, 9/29/2001] )
Fighter Pilots Hear Warning - At least one of the warning messages is heard by District of Columbia Air National Guard (DCANG) fighter pilots who launch from Andrews Air Force Base at 10:42 a.m. (see 10:42 a.m. September 11, 2001) and by pilots launched from Langley Air Force Base by NORAD’s Northeast Air Defense Sector (NEADS) earlier on (see (9:25 a.m.-9:30 a.m.) September 11, 2001). DCANG pilots Marc Sasseville and Heather Penney Garcia are flying at low altitude over Washington, while the three Langley pilots are above them at around 20,000 feet. Although they are on different radio frequencies, both sets of pilots hear a message over a shared channel: “Attention all aircraft monitoring Andrews tower frequency. Andrews and Class Bravo airspace is closed. No general aviation aircraft are permitted to enter Class Bravo airspace. Any infractions will be shot down.” [Filson, 2003, pp. 82]
Officers Hear Warning - The warning messages are also heard by DCANG officers at Andrews. After hearing that violators of the Washington airspace will be shot down, Brigadier General David Wherley thinks to himself, “I guess that will be us doing the shooting.” [Washington Post, 4/8/2002; Vogel, 2007, pp. 446] Apparently referring to the warnings from the Andrews tower, Lieutenant Colonel Phil Thompson will later recall: “We kind of winced at that, because there are plenty of hard reasons to not shoot somebody down. We were really in an ID posture—and trying to really be careful.” [Aviation Week and Space Technology, 9/9/2002]
Shootdown Not Authorized until 10:18 - Although the first of the warnings is broadcast at 10:05 a.m., President Bush only gives authorization for hostile aircraft to be shot down at 10:18 a.m., according to the 9/11 Commission, in a phone call with Vice President Dick Cheney (see 10:18 a.m.-10:20 a.m. September 11, 2001). Furthermore, NEADS only learns that NORAD has been given clearance to shoot down threatening aircraft at 10:31 a.m. (see 10:31 a.m. September 11, 2001). The 9/11 Commission document of Andrews tower transmissions will show that the warnings are broadcast until at least 11:05 a.m., although presumably they continue after that.

Counterterrorism “tsar” Richard Clarke is told by White House Situation Room Deputy Director Ralph Seigler, “Secret Service reports a hostile aircraft ten minutes out.” Two minutes later, he is given an update: “Hostile aircraft eight minutes out.” In actual fact, when Flight 93 crashed at 10:06 a.m., it was still about 15 minutes away from Washington. Clarke is also told that there are 3,900 aircraft still in the air over the continental US (which is roughly accurate); four of those aircraft are believed to be piloted by terrorists (which is inaccurate by this time). Joint Chiefs of Staff Vice Chairman Richard Myers then reports: “We have three F-16s from Langley over the Pentagon. Andrews is launching fighters from the DC Air National Guard. We have fighters aloft from the Michigan Air National Guard, moving east toward a potential hostile over Pennsylvania. Six fighters from Tyndall and Ellington are en route to rendezvous with Air Force One over Florida. They will escort it to Barksdale.” [North American Aerospace Defense Command, 9/18/2001; Clarke, 2004, pp. 8-9] However, fighters do not meet up with Air Force One until about an hour later (see (11:29 a.m.) September 11, 2001). Franklin Miller, a senior national security official who is working alongside Clarke on 9/11, and another official who is also in the Situation Room, will later fail to recall hearing any warning that a plane could be only minutes away. [New York Times, 3/30/2004] The time of this incident is unstated, but the Michigan fighters are not diverted until after 10:06 a.m. (see (After 10:06 a.m.) September 11, 2001). If it takes place after 10:06 a.m., this would parallel similar warnings about Flight 93 after it has already crashed provided to Vice President Dick Cheney elsewhere in the White House (see (Between 10:10 a.m. and 10:15 a.m.) September 11, 2001).

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).

Lewis ‘Scooter’ Libby.Dick Cheney in the White House bunker, speaking to administration officials including (from left) Joshua Bolten, Karen Hughes, Mary Matalin (standing), Condoleezza Rice and I. Lewis ‘Scooter’ Libby. [Source: David Bohrer / White House] (click image to enlarge)The Secret Service, viewing projected path information about Flight 93, rather than actual radar returns, does not realize that Flight 93 has already crashed. Based on this erroneous information, a military aide tells Vice President Dick Cheney and others in the White House bunker that the plane is 80 miles away from Washington. Cheney is asked for authority to engage the plane, and he quickly provides it. The aide returns a few minutes later and says the plane is 60 miles out. Cheney again gives authorization to engage. A few minutes later and presumably after the flight has crashed or been shot down, deputy White House chief of staff Josh Bolten suggests Cheney contact President Bush to confirm the engage order. Bolten later tells the 9/11 Commission that he had not heard any prior discussion on the topic with Bush, and wanted to make sure Bush knew. Apparently, Cheney calls Bush and obtains confirmation (see 10:18 a.m.-10:20 a.m. September 11, 2001). [9/11 Commission, 6/17/2004] However, there is controversy over whether Bush approved a shootdown before this incident or whether Cheney gave himself the authority to make the decision on the spot. As Newsweek notes, it is a moot point in one sense, since the decision was made on false data and there is no plane to shoot down. [Newsweek, 6/20/2004]

A lieutenant colonel at the White House repeatedly relays to the National Military Command Center (NMCC) at the Pentagon that Vice President Dick Cheney has confirmed that fighter jets are cleared to engage an inbound aircraft if they can verify that the aircraft is hijacked. The lieutenant colonel notifies the NMCC of the authorization over the air threat conference call (see 9:29 a.m.-9:34 a.m. September 11, 2001). Cheney, who is in the Presidential Emergency Operations Center (PEOC) below the White House, said at sometime between 10:10 and 10:15 that fighters could engage an aircraft that was reportedly approaching Washington (see (Between 10:10 a.m. and 10:15 a.m.) September 11, 2001). However, it is only when Cheney calls President Bush at 10:18 a.m. that Bush confirms the shootdown order (see 10:18 a.m.-10:20 a.m. September 11, 2001). The shootdown order will be received by NORAD, and then, at 10:31 a.m., sent out to its three air defense sectors in the continental US (see 10:31 a.m. September 11, 2001).

A message is put out on NORAD’s computer chat system, notifying its three air defense sectors in the US that peacetime rules of engagement (ROE) still apply, which means fighter jets are not permitted to shoot down hostile aircraft. As a 9/11 Commission memorandum will later describe, on the chat log it is reiterated at this time “that the defensive posture [is] still peacetime ROE.” The person or organization that issues this message is unstated. NORAD’s computer chat system allows those with the proper access to communicate with each other, similarly to the way members of the public do in Internet chat rooms. The NORAD system includes three main chat rooms. The message about the current rules of engagement goes out in the chat room for the Continental US NORAD Region (CONR). This is where CONR’s three sectors—including the Northeast Air Defense Sector (NEADS), which has been coordinating the military’s response to the hijackings—communicate with each other. [9/11 Commission, 1/22/2004 pdf file; Spencer, 2008, pp. 139] It is not until 10:31 a.m. that Major General Larry Arnold, the CONR commander, will issue an instruction over the chat system, stating that NORAD has been cleared to shoot down threatening aircraft (see 10:31 a.m. September 11, 2001).

A representative of the FAA finally joins an emergency teleconference being conducted by the National Military Command Center (NMCC) at the Pentagon, after NMCC personnel have repeatedly been unable to connect the FAA to the conference. In response to the terrorist attacks, the NMCC began a “significant event conference” at 9:29 a.m., to gather and disseminate information from government agencies (see 9:29 a.m.-9:34 a.m. September 11, 2001), and eight minutes later upgraded this to an “air threat conference” (see 9:37 a.m.-9:39 a.m. September 11, 2001). However, according to the 9/11 Commission Report, because of “equipment problems and difficulty finding secure phone numbers,” operators at the NMCC have been unable to connect the FAA to the conference (see (9:29 a.m.-12:00 p.m.) September 11, 2001). [9/11 Commission, 7/21/2003 pdf file; 9/11 Commission, 7/24/2004, pp. 37]
FAA Representative Has 'No Situational Awareness' - The air threat conference is now joined by FAA employee Rayford Brooks. [9/11 Commission, 7/24/2004, pp. 463] Brooks is on duty in the Central Altitude Reservation Function (CARF) at the FAA’s Command Center in Herndon, Virginia. This office is responsible for processing and separating altitude reservations, and coordinates military requests for priority airspace activity with FAA facilities and international agencies. [9/11 Commission, 4/5/2004; 9/11 Commission, 4/15/2004] However, Brooks has “no familiarity with or responsibility for hijackings, no access to decisionmakers, and none of the information available to senior FAA officials,” according to the 9/11 Commission Report. [9/11 Commission, 7/24/2004, pp. 37] Brooks will later recall having had “no situational awareness” of the current crisis. He only arrived at the Command Center at around 9:30 a.m. and had not been listening to the radio while driving to work. Those on the Command Center floor have not given him any instructions regarding the NMCC conference or other operational matters.
Brooks on Conference instead of Military Cell Officer - Brooks will tell the 9/11 Commission that the Air Traffic Services Cell (ATSC)—a small office located next to the CARF at the Command Center, manned by military reservists (see (Between 9:04 a.m. and 9:25 a.m.) September 11, 2001)—has asked the CARF to monitor the NMCC’s air threat conference on its behalf for three or four hours, because the ATSC does not have a working STU-III secure phone. [9/11 Commission, 4/15/2004] (A chronology of the ATSC’s actions on this day will state that the keys for the ATSC’s secure phones are recalibrated at some point, and these phones then “worked fine.” [US Air Force, 9/11/2001] )
NORAD and FAA Leaders out of Contact - Three times before 10:03 a.m., when the last hijacked plane reportedly crashed (see (10:03 a.m.-10:10 a.m.) September 11, 2001), NORAD asked for confirmation of the FAA’s presence on the NMCC’s conference, so the FAA could provide an update on the hijackings, but the FAA had not been connected at those times. As a result of the FAA’s absence from the conference, the leaders of NORAD and the FAA have effectively been out of contact with each other. [9/11 Commission, 6/17/2004; 9/11 Commission, 7/24/2004, pp. 37-38]
FAA's Absence Caused Confusion over Identities of Hijacked Planes - General Richard Myers, the acting chairman of the Joint Chiefs of Staff, will later write that the lack of communication between the NMCC and the FAA has contributed to confusion at the NMCC over the flight numbers of the aircraft that were hijacked. However, according to Myers, the NMCC could not contact the FAA over ordinary phone lines because “[t]errorists who could hijack aircraft so readily could probably also eavesdrop on unsecured phone lines.” [Myers, 2009, pp. 153]

In a phone call with Vice President Dick Cheney, President Bush authorizes the military to shoot down hostile aircraft. Minutes earlier, in the Presidential Emergency Operations Center (PEOC) below the White House, a military aide had asked Cheney for the authority to engage what appeared to be an inbound aircraft, and Cheney had promptly given it (see (Between 10:10 a.m. and 10:15 a.m.) September 11, 2001). During a subsequent quiet moment, deputy White House chief of staff Josh Bolten, who is also in the PEOC, suggested to Cheney that he contact the president to confirm the engage order. Therefore at 10:18 a.m., according to White House logs, Cheney calls Bush, who is on board Air Force One, and speaks with him for two minutes. White House press secretary Ari Fleischer notes that at 10:20 a.m., Bush informs him that he has authorized the shootdown of aircraft, if necessary. According to the 9/11 Commission, “Fleischer’s 10:20 note is the first mention of shootdown authority.” [9/11 Commission, 7/24/2004, pp. 41 and 465] Bush’s senior adviser Karl Rove, who is also on Air Force One, gives a similar account, later telling NBC News that “at about 10:20,” Bush goes from his office into the private cabin in front of it, “and took a phone call, and came back in and said that he had talked to the vice president and to the secretary of defense and gave the authorization that [the] military could shoot down any planes not under control of their crews that were gearing critical targets.” [MSNBC, 9/11/2002] But other accounts indicate the president gives the shootdown authorization earlier than this. Bush and Cheney will claim that Bush gives the authorization during a call estimated to occur between about 10:00 and 10:15 (see (Between 10:00 a.m. and 10:15 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 40] Similarly, according to journalists Bob Woodward and Bill Sammon, Bush gives it in a call with Cheney soon after 9:56, when Air Force One takes off (see (Shortly After 9:56 a.m.) September 11, 2001). [Sammon, 2002, pp. 102; Woodward, 2002, pp. 17-18; Washington Post, 1/27/2002] Counterterrorism “tsar” Richard Clarke says it is given even earlier.

The Continental United States NORAD Region (CONR) issues a message to its three air defense sectors—including the Northeast Air Defense Sector (NEADS)—stating that Vice President Dick Cheney has authorized it to shoot down suspicious aircraft.
Order Sent over Computer Chat System - About 15 minutes earlier, a military officer at the White House relayed to the Pentagon’s National Military Command Center (NMCC) that Cheney had confirmed that fighter jets were cleared to engage an inbound aircraft if they could verify that the aircraft was hijacked (see 10:14 a.m.-10:19 a.m. September 11, 2001). According to the 9/11 Commission, “It is not clear how [this] shootdown order was communicated within NORAD.” However, Major General Larry Arnold, the CONR commander, now instructs his staff to broadcast a message over a NORAD computer chat system, passing on Cheney’s authorization. The message states, “10:31 Vice president has cleared to us to intercept tracks of interest and shoot them down if they do not respond, per CONR CC [General Arnold].” The message is received at CONR’s three air defense sectors: the Western, Southeast, and Northeast. [9/11 Commission, 7/24/2004, pp. 42; Spencer, 2008, pp. 240]
Arnold Could Issue Shootdown Order Himself - Arnold, who is at the CONR air operations center at Tyndall Air Force Base in Florida, will later comment, “I have the authority in case of an emergency to declare a target hostile and shoot it down under an emergency condition… but it was comforting to know we legally had the authority from the president of the United States.” [Filson, 2002; Code One Magazine, 1/2002; Filson, 2003, pp. 75-76] The 10:31 chat message is the first notification personnel on the NEADS operations floor receive of the shootdown order. These personnel are reportedly confused over the order and do not pass it on to fighter pilots under their command (see 10:32 a.m. September 11, 2001).

Personnel on the operations floor at NORAD’s Northeast Air Defense Sector (NEADS) are confused over the nature and effect of an order they have received, which states that the military can shoot down aircraft that do not respond to its directions, and they do not pass this order on to fighter pilots under their command. [9/11 Commission, 7/24/2004, pp. 42-43; 9/11 Commission, 8/26/2004, pp. 47; Spencer, 2008, pp. 240-241; Farmer, 2009, pp. 228-229] NEADS has just received a message over the NORAD computer chat system from Larry Arnold, the commander of the Continental United States NORAD Region (CONR), stating that Vice President Dick Cheney has authorized NORAD to shoot down suspicious aircraft (see 10:31 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 42]
Weapons Director Alerted to Order - Major Steve Ovens sees the chat message and alerts Major James Fox, the leader of the NEADS weapons team, to it. Ovens says: “We need to read this. Region commander has declared that we can shoot down tracks that do not respond to our direction. Okay?” Fox replies, “Okay,” but Ovens is unconvinced that he has understood Arnold’s message, so he says again, “The region commander has declared that we can shoot down aircraft that do not respond to our directions, okay?” Fox replies, “Copy that.”
NEADS Director Opposes Order - Ovens continues, “So if you’re trying to divert somebody and he won’t divert…” but Fox says, “DO [the director of operations] is saying no.” According to author Lynn Spencer, Fox means that Colonel Lanny McNeely, the NEADS director of operations, is indicating “no.” McNeely has “understood that the battle staff wanted to keep shootdown authority in the [NEADS] battle cab. The commanders were not prepared to pass such authorizations to airborne fighters.” [North American Aerospace Defense Command, 9/11/2001; Spencer, 2008, pp. 240-241] However, a 9/11 Commission memorandum will state that McNeely is away from NEADS on this day, in Texas, and no one is currently sitting in the director of operations position. [9/11 Commission, 10/30/2003 pdf file] According to John Farmer, the senior counsel to the 9/11 Commission, Fox is instead referring to Colonel Robert Marr, the NEADS battle commander, saying “no,” not McNeely. [Farmer, 2009, pp. 229]
Fox Agrees to Pass on Order to Commander - Ovens responds: “No? It came over the chat.… You got a conflict on that direction?” Fox replies, “Right now, no, but…” Showing Fox the chat message, Ovens says: “Okay. You read that from the vice president, right? Vice president has cleared…” Fox reads the message out loud, saying, “Vice president has cleared us to intercept traffic and shoot them down if they do not respond, per CONR CC.” Finally, he says, “Okay, I will pass it to MCC,” meaning Major Kevin Nasypany, the NEADS mission crew commander. [North American Aerospace Defense Command, 9/11/2001; Spencer, 2008, pp. 241]
NEADS Does Not Pass on Order to Pilots - NEADS personnel will later express to the 9/11 Commission their “considerable confusion over the nature and effect” of this shootdown order, and explain why they fail to pass it on to the fighter jets from Otis Air National Guard Base (see 8:46 a.m. September 11, 2001) and Langley Air Force Base (see 9:24 a.m. September 11, 2001) that are under their command. Nasypany and Fox indicate to the Commission that “they did not pass the order to the fighters circling Washington and New York because they were unsure how the pilots would, or should, proceed with this guidance.” Consequently, “while leaders in Washington believed that the fighters above them had been instructed to ‘take out’ hostile aircraft, the only orders actually conveyed to the pilots were to ‘ID type and tail.’” [9/11 Commission, 7/24/2004, pp. 43; Farmer, 2009, pp. 229]

The FAA’s Cleveland Center has to authorize two Ohio Air National Guard fighter jets to shoot down threatening aircraft, because NORAD’s Northeast Air Defense Sector (NEADS) is unable to communicate directly with those jets and give them the authorization itself. [Spencer, 2008, pp. 241-242] The two F-16s, which belong to the 180th Fighter Wing of the Ohio Air National Guard, took off from Toledo Express Airport at 10:17 a.m. (see 10:17 a.m. September 11, 2001). [Toledo Blade, 12/9/2001; WTOL, 9/11/2006]
NEADS Unable to Contact Fighters - NEADS has just received a message, informing it that Vice President Dick Cheney has authorized NORAD to shoot down suspicious aircraft (see 10:31 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 42] A weapons officer wants to pass this important information to the two 180th FW fighter pilots. However, since the jets took off, NEADS has been unable to bring them up on their UHF frequency, and so the weapons officer has had to communicate with them indirectly, via the FAA’s Cleveland Center. He now phones the Cleveland Center and asks it to pass on the new rules of engagement to the 180th FW pilots.
Controller Passes on Shootdown Authorization - A Cleveland Center air traffic controller then radios one of those pilots, Scott Reed, and asks him, “Sting 1-1 [Reed’s call sign], Cleveland Center, do you know what your ROE is?” Reed is surprised to hear a civilian controller use the military acronym for “rules of engagement.” He responds, “Sting 1-1, no.” The controller asks, “Would you like to know?” and then tells Reed, “Sting 1-1, if you have a non-military aircraft moving toward a population center, you are clear to engage.” Reed says, “Cleveland Center, Sting 1-1, please confirm ROE.” The controller responds, “Sting 1-1, if the airplane you are vectored against does not comply with your instructions, you are cleared to engage.” According to author Lynn Spencer, Reed “is shocked; he’s just been given clearance—from a civilian controller—to shoot down a commercial airliner.” [Spencer, 2008, pp. 241-242] The two 180th FW jets never receive any subsequent orders to engage specific aircraft. According to NEADS battle commander, Colonel Robert Marr, the pilots “never had a track close enough that they were directed to engage. [But] if a valid direction had come from the appropriate level to engage a target, or shoot down a target at some time, they could have done that.” [Toledo Blade, 12/9/2001] Though it notifies the 180th FW jets, NEADS fails to pass on the shootdown authorization to the fighters from Otis Air National Guard Base and Langley Air Force Base that are under its command (see 10:32 a.m. September 11, 2001).

Vice President Dick Cheney tries to bring Defense Secretary Donald Rumsfeld up to date over the National Military Command Center’s (NMCC) conference call (see 9:29 a.m.-9:34 a.m. September 11, 2001), as Rumsfeld arrived at the NMCC just minutes earlier (see (10:30 a.m.) September 11, 2001). Cheney explains that he has given authorization for hijacked planes to be shot down and that this has been passed on to the fighter pilots. Rumsfeld asks, “So we’ve got a couple of aircraft up there that have those instructions at the present time?” Cheney replies: “That is correct. And it’s my understanding they’ve already taken a couple of aircraft out.” Then Rumsfeld says: “We can’t confirm that. We’re told that one aircraft is down but we do not have a pilot report that they did it.” Cheney is incorrect about his authorization having reached the pilots (see 10:31 a.m. September 11, 2001).

The North Portal entrance to the Cheyenne Mountain Complex in Colorado.The North Portal entrance to the Cheyenne Mountain Complex in Colorado. [Source: NORAD]The message goes out within NORAD that the military’s defense readiness condition has been raised to Defcon 3. [9/11 Commission, 6/17/2003; 9/11 Commission, 2004] Secretary of Defense Donald Rumsfeld directed that the defense readiness condition be raised from Defcon 5—the lowest level—to Defcon 3 at around 10:45 a.m. (see (10:43 a.m.-10:52 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 326, 554; Goldberg et al., 2007, pp. 131] At 10:52 a.m., an emergency action message about the increased defense readiness condition was issued. [US Department of Defense, 9/11/2001 pdf file; 9/11 Commission, 2004]
NORAD Personnel Learn of Defcon Change - Word of the change is then communicated within NORAD. At 11:03 a.m., NORAD’s Northeast Air Defense Sector (NEADS) is ordered to Defcon 3. Four minutes later, at 11:07 a.m., Lieutenant Colonel Steve Usher, the director of combat operations at the headquarters of the Continental United States NORAD Region (CONR) in Florida, announces that Defcon 3 has been ordered. [9/11 Commission, 6/17/2003] And a military log will state that “NORAD has directed Defcon change” at 11:12 a.m. [9/11 Commission, 2004] Staff Sergeant Brent Lanier, an emergency action controller in NORAD’s Cheyenne Mountain Operations Center (CMOC) in Colorado, is tasked with sending out a message about the change to the defense readiness condition. He will later recall: “I’d sent out false Defcon messages during exercises, but I never thought I’d have to send out an actual Defcon change message—but I did. It was frightening.” [Airman, 3/2002]
NORAD Officers Discuss Defcon Change - Major General Larry Arnold, the CONR commander, will tell the 9/11 Commission that he hears of the change to the defense readiness condition either from Major General Rick Findley, the director of operations at the CMOC, or from one of NORAD’s computer chat logs. [9/11 Commission, 2/3/2004 pdf file] Usher will tell the 9/11 Commission that the instruction to raise the defense readiness condition comes either from the CONR Regional Air Operations Center or from Arnold. He will add that there is an emergency action message confirming the transition. [9/11 Commission, 2/4/2004 pdf file] Arnold will recall that, at some unspecified time, he calls General Ralph Eberhart, the commander of NORAD, about the change to the defense readiness condition, with the intention of informing Eberhart “of what was ongoing.” [9/11 Commission, 2/3/2004 pdf file]
Change in Defcon Affects Who Can Declare a Target Hostile - Steve Hedrick, an air weapons officer at NEADS, will tell the 9/11 Commission that “any change in Defcon is authenticated immediately” with the fighter jets under NORAD control. He will also say that “the main change when a Defcon level changes is in who has the authority to declare a target hostile.” Hedrick will note that the order from Vice President Dick Cheney, that NORAD fighters were “cleared… to intercept tracks of interest and shoot them down if they do not respond” (see 10:31 a.m. September 11, 2001), is “distinct and different from the transition in Defcon levels.” [9/11 Commission, 10/27/2003 pdf file; 9/11 Commission, 7/24/2004, pp. 42]

John Farmer.John Farmer. [Source: Publicity photo]The team of investigators on the 9/11 Commission that is investigating the events of the morning of September 11 comes to believe that a key part of Vice President Dick Cheney’s account is false. The team, led by John Farmer, is convinced that the decision to authorize the military to shoot down threatening aircraft on 9/11 was made by Cheney alone, not by President Bush. According to journalist and author Philip Shenon: “If Farmer’s team was right, the shootdown order was almost certainly unconstitutional, a violation of the military chain of command, which has no role for the vice president. In the absence of the president, military orders should have been issued by Defense Secretary [Donald] Rumsfeld, bypassing the vice president entirely.”
No Evidence - Other than Cheney’s own account of his actions that morning, and a subsequent attempt Bush made to confirm this account, the team has found no evidence that the president was involved in making the shootdown decision before Cheney issued the order, and much evidence that he was unaware of this decision. Shenon will describe: “Even in moments of crisis, the White House keeps extraordinary records of communications involving Bush and his senior staff; every phone call is logged, along with a detailed summary of what happened during the call.… But for 9/11, the logs offered no evidence of a call between Cheney and Bush in which Bush authorized a shootdown. And Farmer’s team reviewed more than just one set of communications logs. There were seven of them—one maintained by the White House telephone switchboard, one by the Secret Service, one by the Situation Room, and four separate logs maintained by military officers working in the White House.” [Shenon, 2008, pp. 265-266]
Issued by Cheney - The Commission believes Cheney issued the shootdown order between around 10:10 a.m. and 10:15 a.m. on 9/11, in response to reports of an aircraft heading toward Washington (see (Between 10:10 a.m. and 10:15 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 41]
No Notes - Yet deputy White House chief of staff Josh Bolten, who was with Cheney at the time, had reportedly “not heard any prior conversation on the subject [of shooting down aircraft] with the president.” As Newsweek describes: “Nor did the real-time notes taken by two others in the room, Cheney’s chief of staff, ‘Scooter’ Libby—who is known for his meticulous record-keeping—or Cheney’s wife, Lynne, reflect that such a phone call between Bush and Cheney occurred or that such a major decision as shooting down a US airliner was discussed.… National Security Adviser Condoleezza Rice and a military aide said they remembered a call, but gave few specifics.” [Newsweek, 6/20/2004] The notes of White House press secretary Ari Fleischer, who had been on Air Force One with the president, show no reference to a shootdown order until several minutes after Cheney issued it (see 10:18 a.m.-10:20 a.m. September 11, 2001).
"Completely Understandable" - Daniel Marcus, the general counsel of the 9/11 Commission, will later say he thought: “[I]n many ways, it would have been completely understandable for Cheney to issue a shootdown order without authorization from Bush. Whatever the constitutional issues, it would have been difficult to second-guess Cheney about a decision to save the White House from destruction if a suicide hijacker was bearing down on the capital and there were only seconds to act.” Yet, as Marcus will recall, Cheney’s staff is “obsessed with showing that he didn’t give the order.” [Shenon, 2008, pp. 266-267]
Cheney Angry - White House lawyers will subsequently lobby the 9/11 Commission to amend its treatment of the shootdown issue in one of its staff reports (see June 15, 2004). [Newsweek, 6/20/2004] And, on this same issue, an angry Cheney will try to get the 9/11 Commission Report changed just before it is released (see Shortly Before July 22, 2004). [Shenon, 2008, pp. 411-412]
