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.

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.
