Air traffic controllers at Washington’s Reagan National Airport fail to notify the Pentagon and a nearby Army airfield about an unidentified aircraft, later determined to be Flight 77, which they are tracking as it approaches the capital. [US Army Center for Military History, 11/14/2001 pdf file; 9/11 Commission, 8/26/2004, pp. 33]
Controllers Call Secret Service but Not Military - Controllers in the Terminal Radar Approach Control (TRACON) at Reagan National Airport are aware of the unidentified, fast-moving aircraft that is approaching the White House from at least as early as 9:33 a.m. (see (9:33 a.m.) September 11, 2001). [Federal Aviation Administration, 9/17/2001 pdf file; 9/11 Commission, 7/24/2004, pp. 9, 39; Spencer, 2008, pp. 145-146] (However, those in the airport’s control tower possibly only learn of it slightly later (see (9:36 a.m.) September 11, 2001). [Spencer, 2008, pp. 158] ) Although a supervisor at the TRACON promptly alerts the Secret Service at the White House to the aircraft (see (9:33 a.m.) September 11, 2001), none of the Reagan Airport controllers contact the Pentagon or the nearby Davison Army Airfield about it. [Federal Aviation Administration, 9/17/2001 pdf file; US Army Center for Military History, 11/14/2001 pdf file]
Aviation Unit Located near Pentagon - Davison Army Airfield is located at Fort Belvoir, an Army base 12 miles south of the Pentagon. The airfield’s principal missions include maintaining “a readiness posture in support of contingency plans,” exercising “operational control” of the local airspace, and providing “aviation support for the White House, US government officials, Department of Defense, Department of the Army, and other government agencies.” The 12th Aviation Battalion, which is the aviation support unit for the Military District of Washington, is stationed at Davison Airfield. The battalion operates UH-1 “Huey” and UH-60 Black Hawk helicopters. [Pentagram, 5/7/1999; Military District of Washington, 8/2000] Its airfield operations unit—Davison Airfield Management—operates and maintains the heliport at the Pentagon. [Soldiers Magazine, 7/2006]
Tower Supervisor Unhappy - The supervisor of air traffic control currently working in the control tower at Davison Airfield will be unhappy about the failure of the Reagan Airport controllers to alert his unit or the Pentagon to the approaching aircraft. He will voice his complaints when he later talks to one of those controllers. The supervisor will later recall: “I was asking him, ‘Did you know that the aircraft was coming this way?’ And he said: ‘Yes. We were tracking him for so many miles.’”
Controller: 'It Never Occurred to Me' to Call Military - The supervisor will ask the controller: “Why you didn’t say anything to Davison? Why you didn’t say anything to the Pentagon? Because if you would have said something, my controller at the Pentagon would have called the DPS unit,” meaning the Defense Protective Service, which guards the Pentagon, “and it would have alerted them that there was something coming to Washington, DC, an aircraft with hostile intentions or something.” The controller will reply, “Well, you know what, it never occurred to me,” and say, “we didn’t know that he was going to hit the Pentagon.” [US Army Center for Military History, 11/14/2001 pdf file]

After seeing the explosion from the attack on the Pentagon, air traffic controllers at Washington’s Reagan National Airport promptly alert others to the crash, with a supervisor reporting that the crashed aircraft was an American Airlines 757. [Federal Aviation Administration, 9/18/2001; Spencer, 2008, pp. 158-159] Reagan Airport is less than a mile from the Pentagon. [St. Petersburg Times, 9/19/2001] In its control tower, supervisor Chris Stephenson had looked out the window and seen Flight 77 approaching (see (9:36 a.m.) September 11, 2001). He watched it flying a full circle and disappearing behind a building in nearby Crystal City, before crashing into the Pentagon. Stephenson sees the resulting fireball and a mass of paper debris that fills the air. He calls the airport’s Terminal Radar Approach Control (TRACON) and reports: “It was an American 757! It hit the Pentagon. It was a 757 and it hit the Pentagon. American!” [USA Today, 8/11/2002; Spencer, 2008, pp. 158-159] Other controllers see the fireball from the crash. One of them, David Walsh, activates the crash phone, which instantly connects the control tower to airport operations, as well as fire and police departments. He yells down the line: “Aircraft down at the Pentagon! Aircraft down at the Pentagon!” [Federal Aviation Administration, 9/18/2001; McDonnell, 2004, pp. 19-20 pdf file; Spencer, 2008, pp. 158-159] Reagan Airport controllers contact controllers at Washington Dulles International Airport, who hear over the speakers in their room: “Dulles, hold all of our inbound traffic. The Pentagon’s been hit.” [ABC News, 10/24/2001]
