Brothers Nawaf Alhazmi and Salem Alhazmi, two of the men who will allegedly hijack Flight 77, go through a security screening checkpoint at Washington’s Dulles International Airport. They are screened at the west checkpoint in the airport’s main terminal. Both men have one carry-on bag. After entering the checkpoint, Salem Alhazmi walks through a metal detector without setting off the alarm and so is allowed to continue on his way. However, Nawaf Alhazmi sets off the alarm when he passes through it and so he has to walk through a second metal detector. He again sets off the alarm. He is therefore hand-wanded by a member of staff and has his carry-on bag swiped by an explosive trace detector. These checks apparently find no problems and so he is allowed to proceed on his way. Salem Alhazmi’s bag is not physically inspected while the two men are at the checkpoint, nor are the contents of Nawaf Alhazmi’s bag. Security camera footage will later reveal that Nawaf Alhazmi has an unidentified item clipped to the rim of the back pocket of his pants. One of the other Flight 77 hijackers passed through the west checkpoint a minute ago (see 7:35 a.m. September 11, 2001) and two more passed through it 17 minutes before that (see 7:18 a.m. September 11, 2001). The FAA’s Washington Civil Aviation Security Field Office will investigate the security screening at Dulles Airport today and the screeners who were on duty will recall having encountered no suspicious activity and nothing out of the ordinary this morning.

7:40 a.m. September 11, 2001: Flight 11 Pushes Back from Gate; Reports Conflict over Which Gate It Leaves From
American Airlines Flight 11 pushes back from the gate at Boston’s Logan Airport. [9/11 Commission, 7/24/2004, pp. 2] There are discrepancies over which gate it leaves from. Most early reports state that it pushes out from Gate 26 in Terminal B of the airport. [Boston Globe, 9/12/2001; Chicago Sun-Times, 9/13/2001; Daily Telegraph, 9/16/2001; Washington Post, 9/16/2001; Bernstein, 2002, pp. 179; Der Spiegel, 2002, pp. 36] However, one unnamed Logan Airport employee will say it leaves from Gate 32, also in Terminal B. [Boston Globe, 9/11/2001] The transcript of radio communications with the flight confirms it left from Gate 32, and the 9/11 Commission also later states this. [New York Times, 10/16/2001; 9/11 Commission, 7/24/2004, pp. 451] The reason for the discrepancy in these reports is unclear. Flight 11, a Boeing 767 with a capacity of 158 passengers, is about half full on this day, with 81 passengers on board (including the five hijackers), along with the two pilots and nine flight attendants. [9/11 Commission, 8/26/2004, pp. 6] It will take off at 7:59 (see (7:59 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 4]
Before 7:59 a.m. September 11, 2001: Inter Flight Phone Call Between Hijackers
Hijacker Mohamed Atta on Flight 11 calls hijacker Marwan Alshehhi in Flight 175 as both planes sit on the runway. They presumably confirm the plot is on. [Time, 8/4/2002]
7:45 a.m. September 11, 2001: Hijackers’ Bags Contain Airline Uniforms
Hijackers Mohamed Atta and Abdulaziz Alomari board Flight 11. Atta’s bags are not loaded onto the plane in time and will later be found by investigators. Investigators will discover airline uniforms in one of the bags. [Boston Globe, 9/18/2001] It will not be explained why Atta would have obtained these uniforms only to put them in his checked-in baggage, where he would be unable to access them.
7:59 a.m. September 11, 2001: Flight 11 Is Late Taking Off
Flight 11 takes off from Boston’s Logan Airport, 14 minutes after its scheduled 7:45 departure time. [Washington Post, 9/12/2001; CNN, 9/17/2001; Los Angeles Times, 9/20/2001; Guardian, 10/17/2001; ABC News, 7/18/2002; Associated Press, 8/21/2002; Newsday, 9/10/2002; 9/11 Commission, 6/17/2004

Shortly Before 8:00 a.m. September 11, 2001: Two Passengers Allegedly Get Off Flight 93 Just Before Take-off
Two passengers leave Flight 93 after hearing an announcement that there will be a five-minute delay in the plane pushing back from the gate. This is according to Terry Tyksinski, a longtime flight attendant with United Airlines, who says a customer service supervisor who witnessed the incident told her about it six months after 9/11. The two first-class passengers are reportedly of dark complexion, “kind of black, not black.” According to Tyksinski, the supervisor notes their names and is subsequently twice interviewed by the FBI. [Longman, 2002, pp. xiii-xiv] No other accounts, including the 9/11 Commission Report, mention this incident. [9/11 Commission, 7/24/2004] And while Flight 93 is delayed on the ground until 8:42 a.m., reports state that it pushes back from the gate just one minute later than its scheduled departure, rather than there being a five-minute delay as Tyksinski suggests. [Boston Globe, 11/23/2001; MSNBC, 9/11/2006] There will only be 37 passengers on Flight 93, including the four hijackers. This is 20 percent of the plane’s passenger capacity of 182 and, according to the 9/11 Commission, “is considerably below the 52 percent average load factor for Flight 93 for Tuesdays in the three-month period prior to September 11.” [9/11 Commission, 8/26/2004, pp. 36]
8:00 a.m. September 11, 2001: President Bush Briefly Meets Local Law Enforcement Officials
Having returned to the Colony Beach and Tennis Resort after his morning jog, President Bush meets for a brief chat in his penthouse suite with Manatee County Sheriff Charlie Wells, Sarasota County Sheriff Bill Balkwill, Sarasota Police Chief Gordon Jolly, and Manatee County Sheriff’s Colonel Ken Pearson. Wells later recalls the president was “totally unsuspecting about what is to happen.… It looked like, to me, he’s saying, ‘Glad to see you, but I’m ready to get on to the school and meet the kids.’” The four law enforcement officials will later travel to the Sarasota school in the president’s motorcade. [Sammon, 2002, pp. 36; Sarasota Herald-Tribune, 9/10/2002]
8:00 a.m. September 11, 2001: Neil Bush, Brother of the President, Is at the White House after Staying There Overnight
White House staffers are taking care of the activities of Neil Bush, a younger brother of President Bush, who has just spent the night at the White House. It is unclear why Neil Bush has been staying at the White House. When he later recalls the events of this morning, Gary Walters, the chief White House usher, will only say, “We… had had the president’s brother, Neil, there overnight, so we were taking care of his activities during the day, because he was going out for business.” [C-SPAN, 7/11/2011] After heading out for “business,” Neil Bush will return to the White House later this morning following the terrorist attacks. The Cincinnati Enquirer will report that he “arrived at the White House on the morning of September 11 and found ‘a war atmosphere,’ soldiers with machine guns at every turn.” [Cincinnati Enquirer, 1/29/2002] Details of Neil Bush’s activities later today are unclear. However, he will, like last night, spend tonight at the White House (see 11:08 p.m. September 11, 2001). [Sammon, 2002, pp. 134; New York Times, 9/11/2002] Neil Bush is a businessman who runs Ignite Learning, an educational software company he co-founded in 1999. [Cincinnati Enquirer, 1/29/2002; Washington Post, 12/28/2003] George H. W. Bush and Barbara Bush, the parents of the president, also spent last night at the White House (see (8:00 a.m.) September 11, 2001). [Andersen, 2002, pp. 2; CNN, 10/25/2003]
Early Morning September 11, 2001: Helicopter Crew at Aviation Unit near Pentagon Away for ‘Traffic Survey’
A helicopter and its crew that are always on standby for “contingency” missions in the Washington area are away from base early this morning conducting a traffic survey, but apparently return at some point before the Pentagon is hit. The crew belongs to the 12th Aviation Battalion. [US Army Center for Military History, 11/14/2001
; Army Center of Military History, 11/14/2001
] The 12th Aviation Battalion is stationed at Davison Army Airfield at Fort Belvoir, located 12 miles south of the Pentagon. It is the aviation support unit for the Military District of Washington, and operates UH-1 “Huey” and UH-60 Black Hawk helicopters. [Military District of Washington, 8/2000] According to a chief warrant officer with the unit, the 12th Aviation Battalion has “two crews that are always on standby for any kind of contingency mission.” It is one of these crews that is “out flying around doing a traffic survey.” [Army Center of Military History, 11/14/2001
] The exact time period during which the crew and their helicopter are away from base is unstated, but they apparently return to Davison Airfield before 9:37 a.m., when the Pentagon is hit (see Shortly Before 9:37 a.m. September 11, 2001). [US Army Center for Military History, 11/14/2001
] They will be the first crew with the battalion to take off in support of the rescue operations at the Pentagon once the unit’s aircraft are permitted to launch again following the attack. Others members of the 12th Aviation Battalion are also away from base this morning, for weapons training (see 8:46 a.m.-9:37 a.m. September 11, 2001). [Army Center of Military History, 11/14/2001

8:00 a.m. September 11, 2001: NORAD Operations Center in Colorado Participating in ‘Simulated Air War’ Training Exercise
Personnel in NORAD’s operations center in Cheyenne Mountain, Colorado, take part in a major Cold War-style training exercise called Vigilant Guardian, a war game in which the theoretical enemy is Russia. [9/11 Commission, 3/1/2004
; Denver Post, 8/28/2011; Colorado Springs Gazette, 9/10/2011] All of NORAD, including its subordinate units (see (6:30 a.m.) September 11, 2001), participates in the exercise. [Northeast Air Defense Sector, 8/23/2001; Canadian Broadcasting Corporation, 9/8/2011] More than 50 people in the NORAD Battle Management Center in Cheyenne Mountain take part. [Airman, 3/2002; Defense Video and Imagery Distribution System, 9/8/2011] Vigilant Guardian is an annual exercise and is scheduled to last two weeks. [Arkin, 2005, pp. 545; Canadian Broadcasting Corporation, 9/8/2011] It has been underway for several days. Those in the Cheyenne Mountain Operations Center (CMOC) have been participating in it “for at least three or four days,” according to Lieutenant Colonel Steven Armstrong, NORAD’s chief of plans and forces. [North American Aerospace Defense Command, 9/9/2011]
Vigilant Guardian Is a ‘Full-Blown Nuclear War’ Exercise – Vigilant Guardian is a “transition to wartime operations command post exercise,” according to an information page for its participants. [Northeast Air Defense Sector, 8/23/2001] The 1st Air Force’s book about 9/11 will describe it as a “simulated air war.” [Filson, 2003, pp. 55] Lieutenant Colonel William Glover, the commander of NORAD’s Air Warning Center, will later recall that it involves NORAD “simulating war.… You know, attacks coming from the outside, Soviet-style bombers coming in, cruise-missile attacks, that type of thing.” [Canadian Broadcasting Corporation, 9/8/2011] Ken Merchant, NORAD’s joint exercise design manager, will tell the 9/11 Commission that Vigilant Guardian is a “full-blown nuclear war” exercise, and includes bomber response and intercontinental ballistic missile response. [9/11 Commission, 3/4/2004]
Russia Is Imagined Enemy – The theoretical enemy in the exercise is Russia. [Denver Post, 8/28/2011] According to the 9/11 Commission Report, the exercise “postulated a bomber attack from the former Soviet Union.” [9/11 Commission, 7/24/2004, pp. 458] Merchant will explain that “NORAD must use Russia in its exercises at the strategic level since no other country poses a great enough threat to NORAD’s capabilities and responsibilities.” [9/11 Commission, 3/4/2004]
Personnel Updated on Exercise during Shift Change – Armstrong will later recall that today starts off “like any other day. We came in thinking it would be a normal day… we did a standard shift changeover in the morning and we were getting right into where we were at in relation to the exercise.” He will describe that in a shift change during the exercise, “We’d say, ‘Okay, here’s what happened during the night shift (or the day shift),’ and we’d give each other an update, and then we’d start planning for whatever was on the agenda for that day.” [North American Aerospace Defense Command, 9/9/2011] According to the Denver Post, after commencing his shift, Armstrong “mapped out strategy in a chess game of ever-escalating scenarios, from strained diplomacy to the outbreak of conventional warfare that headed inexorably toward nuclear conflict” with Russia. [Denver Post, 8/28/2011]
B-1 Bomber Scheduled to Fly out over Pacific Ocean – The “planned big event for the day” in the exercise is “supposed to be a B-1 bomber that was flying out of Fairchild Air Force Base [in Washington State] and going out over the Pacific,” according to Jeff Ford, an Air Force lieutenant colonel who is working in the CMOC. Ford will add that there are “other things going on as part of the exercise, air exercise events, and then some scripted inputs that we were reacting to there in the Air Warning Center, whether it be unknown aircraft that we scramble aircraft for to intercept—or whatever.” [Defense Video and Imagery Distribution System, 9/8/2011]
Exercise Posture Allegedly Helps Response to Attacks – Vigilant Guardian will reportedly end after 9:03 a.m., when the second plane hits the World Trade Center (see (Shortly After 9:03 a.m.) September 11, 2001), and the CMOC personnel participating in it will then become involved in responding to the real-world attacks. [Airman, 3/2002; Toronto Star, 11/11/2008] Glover will claim that the CMOC’s response to the terrorist attacks benefits from the position the operations center is in for the exercise. He will say NORAD is “lucky” because “all the directorates such as operations, logistics, security, all those folks were up in the [Cheyenne] Mountain on an exercise posture.” He will add that “these are the same folks that we would bring up in case of contingencies or in time of going to war. So, in reality, I had all the guys up into the NORAD Battle Management Center that I needed to conduct the exercise as well as the contingency operations that happened on 9/11.” [Defense Video and Imagery Distribution System, 9/8/2011]
NORAD Monitoring Russian Exercise – NORAD was created in 1958, during the Cold War, to protect North American airspace against nuclear attacks from the Soviet Union. [New York Times, 4/25/2004; Canadian Broadcasting Corporation, 8/6/2004; Legion Magazine, 11/2004] According to the Toronto Star, “Whether it’s a simulation or a real-world event, the role of the [CMOC] is to fuse every critical piece of information NORAD has into a concise and crystalline snapshot.” [Toronto Star, 12/9/2001] As well as the Vigilant Guardian exercise, NORAD is currently in the middle of an operation called Northern Vigilance, with its fighter jets deployed to Alaska and Northern Canada to monitor an exercise being run by the Russian Air Force (see September 9, 2001). [North American Aerospace Defense Command, 9/9/2001] The battle staff members in Cheyenne Mountain are positioned to deal with both this operation and the exercise. [9/11 Commission, 3/1/2004
