Counterterrorism “tsar” Richard Clarke begins a crisis response video conference by asking FAA Administrator Jane Garvey what she knows. Garvey replies: “The two aircraft that went in [to the WTC] were American flight 11, a 767, and United 175, also a 767. Hijacked.” She says that she has put a hold on all takeoffs and landings in New York and Washington, then states, “We have reports of eleven aircraft off course or out of communications.” Clarke and Garvey discuss the feasibility of canceling all takeoffs nationally, and grounding all planes in the air. Garvey says it is possible, but will take time. [Clarke, 2004, pp. 4-5]
