Preparations are underway at the Pentagon heliport, located about 150 feet from the west side of the building, for the expected arrival of President Bush at around midday. Bush had left from the Pentagon the previous day for his visit to Florida. He occasionally uses the Pentagon heliport rather than the White House grounds when going by helicopter to and from Air Force One at Andrews Air Force Base. [Goldberg et al., 2007, pp. 64] The White House grounds are unavailable because the annual Congressional picnic is scheduled to take place there this afternoon. The White House hosts this event for members of Congress and select staffers; around 1,200 guests are due to attend, until the attacks lead to it being canceled. [Scripps Howard News Service, 9/11/2001; Scheib and Friedman, 2007, pp. 254-255; Hayes, 2007, pp. 344] Three firefighters from the fire department at nearby Fort Myer had arrived at the Pentagon at around 7:30 a.m. to man the fire station next to the heliport.

; Goldberg et al., 2007, pp. 65] “Every day they have an aircraft flying, we’re there,” firefighter Alan Wallace will later explain. [Pentagram, 9/14/2001] Wallace decides to pull the fire truck out of the fire station and place it in a position more accessible to the heliport landing pad. [First Due News, 4/17/2003] The truck is equipped with the special chemical foam used in fighting jet fuel fires. [Goldberg et al., 2007, pp. 65] Wallace parks it about 15 feet from the Pentagon’s west wall, facing toward the landing pad. Wallace will recall that with many vehicles—belonging to the Secret Service and other agencies—expected to be around for the president’s arrival, he “wanted the crash truck out of the station and parked in a good location, for easy access to the heliport in case of an emergency.” [First Due News, 4/17/2003] When the Pentagon is hit at 9:37 a.m., the aircraft will crash into an area of the building next to the heliport (see 9:37 a.m. September 11, 2001).

9:20 a.m. September 11, 2001: Fire Chief Warns Firefighters at Pentagon that Washington Could be Target for Attack
A fire chief calls his firefighters who are manning the fire station at the Pentagon’s heliport, and warns them that there could be more attacks, and Washington could be a target. [First Due News, 4/17/2003; Creed and Newman, 2008, pp. 20-21] Chief Charles Campbell works with the fire department at Fort Myer, an army base 1.5 miles northwest of the Pentagon, which sends three of its firefighters each day to man the fire station at the Pentagon heliport. [Pentagram, 11/2/2001] Campbell calls the station to make sure his firefighters there—Alan Wallace, Mark Skipper, and Dennis Young—are aware of what is going on in New York. He tells them, “These were intentional acts of terrorism.” He speaks “to each of the three firefighters, making sure they [are] all on their toes and ready to respond to an unexpected incident.” Wallace will recall that Campbell “wanted to be sure we were aware of everything going on around the fire station.” Campbell says there could be more attacks, and that “If it had happened in New York, it could happen in Washington.” As Wallace recalls, Campbell says “Washington, DC could very well be a target and if that happened, our fire truck could be dispatched to an incident.” [First Due News, 4/17/2003; Creed and Newman, 2008, pp. 20-21] Yet, while Campbell believes an attack on Washington is likely, neither the Pentagon nor any government buildings in Washington will be evacuated before the Pentagon is hit at 9:37 (see Before 9:37 a.m. September 11, 2001 and Before 9:37 a.m. September 11, 2001). [CNN, 9/16/2001] The Fort Myer firefighters will narrowly escape suffering serious injuries when the Pentagon attack occurs (see 9:37 a.m. September 11, 2001). [Pentagram, 11/2/2001]
9:36 a.m.-9:39 a.m. September 11, 2001: Emergency Workers See and Promptly Report Low-Flying Flight 77 Approaching the Pentagon and Crashing
Several police officers and firefighters see the low-flying Flight 77 as it approaches the Pentagon and crashes. They quickly report this to their own agencies or to the Arlington County Emergency Communications Center (ECC), which is the focal point of all police and fire 911 calls for the county. [Goldberg et al., 2007, pp. 66] 
Arlington County Police Department Corporal Barry Foust is stopped at traffic lights less than two miles from the Pentagon, and spots the aircraft flying low, then sees a plume of smoke. [Goldberg et al., 2007, pp. 13] He immediately calls the ECC and calmly reports: “I think we just had an airplane crash east of here. Must be in the District area.” [Washington Post, 9/17/2001; Associated Press, 9/18/2001; US Department of Health and Human Services, 7/2002, pp. C6 ] Police Motorcycle Officer Richard Cox is standing near a diner less than a mile from the Pentagon. Hearing a sudden roar, he turns and reportedly sees the plane “directly overhead… no more than a hundred feet off the ground.” [Vogel, 2007, pp. 427] He calls the ECC and reports, “It’s an American Airlines plane headed eastbound over the [Columbia] Pike, possibly headed for the Pentagon.” [Washington Post, 9/17/2001; Associated Press, 9/18/2001; US Department of Health and Human Services, 7/2002, pp. C6 ] Fire Captain Steve McCoy and his crew are traveling north on Interstate 395 in ACFD Engine 101, for a training session in Crystal City. McCoy reportedly sees “a commercial airliner in steep descent, banking sharply to its right before disappearing beyond the horizon,” followed by “a tremendous explosion” and “a massive plume of smoke and fire.” He immediately radioes ECC and reports, “We got a plane down, it looks like in the Crystal City area by the 14th Street Bridge.” Being aware of the attacks on the World Trade Center, he advises that the FBI should be notified, as this is a possible terrorist attack. [US Department of Health and Human Services, 7/2002, pp. A4 ; Goldberg et al., 2007, pp. 66] Officer Mark Bright of the Defense Protective Service (DPS)—the Pentagon’s police force—is manning the security booth at the Pentagon’s Mall entrance, when he hears a loud noise. He will recall: “I saw the plane at the Navy Annex area [a few hundred yards from the Pentagon]. I knew it was going to strike the building because it was very, very low—at the height of the street lights.” As soon as he sees it hit the Pentagon he radioes in his report of the attack, and then speeds in his police cruiser to the crash site, becoming the first officer there. [American Forces Press Service, 9/24/2001; Washington Post, 10/25/2001; Goldberg et al., 2007, pp. 152] Sergeant William Lagasse, also a member of the DPS, is filling up his patrol car at a gas station near the Pentagon. He recalls that he sees an “American Airlines 757… approximately 100 feet above the ground level, maybe 60 feet in front of me.” He watches the plane crash into the Pentagon. His first reaction is to call the DPS Communications Center and state, “An aircraft has just flown into the side of the building.” He then grabs his medical bag and dashes to the crash scene. [Washington Post, 10/25/2001; Library of Congress, 12/4/2001] Alan Wallace and Mark Skipper of the Fort Myer Fire Department are manning the fire station by the Pentagon heliport, and are outside checking their truck. Wallace glances up and sees the plane coming at them, and the two men then dive for cover (see 9:37 a.m. September 11, 2001). Wallace promptly radioes the fire department headquarters at Fort Myer, and reports that an airliner has hit the west side of the Pentagon. [Goldberg et al., 2007, pp. 65]
Partly due to these calls, many emergency responders quickly learn of the crash and are able to arrive at the Pentagon within minutes of it (see 9:40 a.m.-9:43 a.m. September 11, 2001). [Goldberg et al., 2007, pp. 66] Some fire and rescue units from Arlington County and elsewhere also respond—self-dispatching from stations or diverting from other destinations—after hearing Captain McCoy’s radio message to the ECC. [US Department of Health and Human Services, 7/2002, pp. A4 ]
9:37 a.m. September 11, 2001: Fireman Dodges Flight 77; Immediately Notifies Superior about Crashed Jumbo Jet
Fireman Alan Wallace is busy with a safety crew at the Pentagon’s heliport pad. As Wallace is walking in front of the Pentagon, he looks up and sees Flight 77 coming straight at him. It is about 25 feet off the ground, with no landing wheels visible, a few hundred yards away, and closing fast. He runs about 30 feet and dives under a nearby van. [Washington Post, 9/21/2001] The plane is traveling at about 460 mph, and flying so low that it clips the tops of streetlights. [CBS News, 9/21/2001] Using the radio in the van, he calls his fire chief at nearby Fort Myer and says, “We have had a commercial carrier crash into the west side of the Pentagon at the heliport, Washington Boulevard side. The crew is OK. The airplane was a 757 Boeing or a 320 Airbus.” [Scripps Howard News Service, 8/1/2002]
