According to the 9/11 Commission: “An Air Force lieutenant colonel working in the White House Military Office [joins] the [NMCC’s air threat] conference and state[s] that he had just talked to Deputy National Security Adviser Stephen Hadley. The White House request[s]: (1) the implementation of Continuity of Government measures, (2) fighter escorts for Air Force One, and (3) the establishment of a fighter combat air patrol over Washington, DC.” [9/11 Commission, 6/17/2004 ] Counterterrorism “tsar” Richard Clarke gave the order to implement the Continuity of Government plan a few minutes earlier, from inside the White House Situation Room (see (Between 9:45 a.m. and 9:56 a.m.) September 11, 2001). Before that, he had requested a fighter escort for Air Force One (see (Between 9:30 a.m. and 9:37 a.m.) September 11, 2001) and combat air patrols over all major US cities (not just Washington), according to his own recollection (see (Between 9:38 a.m. and 9:45 a.m.) September 11, 2001).
