(9:37 a.m.) September 11, 2001: Counterterrorism ‘Tsar’ Clarke Learns of Aircraft Approaching White House

Barbara Riggs.Barbara Riggs. [Source: Miles B. Norman / Elmira Star-Gazette]Counterterrorism “tsar” Richard Clarke learns of an aircraft heading toward the White House. Clarke, who is in the White House Situation Room, is passed a note by Secret Service Director Brian Stafford, which says, “Radar shows aircraft headed this way.” [Clarke, 2004, pp. 7] Around this time, the FAA’s Boston Center is reporting a low-flying aircraft six miles southeast of the White House (see 9:36 a.m. September 11, 2001), so this is presumably the same airliner to which Stafford’s note refers. [Vanity Fair, 8/1/2006] Clarke later comments that the Secret Service is aware of the approaching plane because it has “a system that allowed them to see what FAA’s radar was seeing.” [Clarke, 2004, pp. 7] Secret Service agent Barbara Riggs, who is in the agency’s Washington headquarters, will later corroborate this, recalling: “Through monitoring radar and activating an open line with the FAA, the Secret Service was able to receive real time information about… hijacked aircraft. We were tracking two hijacked aircraft as they approached Washington, DC, and our assumption was that the White House was a target.” [PCCW Newsletter, 3/2006] Stafford informs Clarke that he is going to evacuate the White House complex. (This evacuation appears to take place at around 9:45 (see (9:45 a.m.) September 11, 2001).) Those in the Situation Room are then informed that there has been an explosion at the Pentagon, and soon after that a plane has hit it. [Clarke, 2004, pp. 7]
