At some time between 10:10 and 10:15, a military aide told the Vice President and others that the aircraft was 80 miles out. Vice President Cheney was asked for authority to engage the aircraft.218 His reaction was described by Scooter Libby as quick and decisive, “in about the time it takes a batter to decide to swing.” The Vice President authorized fighter aircraft to engage the inbound plane. He told us he based this authorization on his earlier conversation with the President.The military aide returned a few minutes later, probably between 10:12 and 10:18, and said the aircraft was 60 miles out. He again asked for authorization to engage.The Vice President again said yes.

At the conference room table was White House Deputy Chief of Staff Joshua Bolten. Bolten watched the exchanges and, after what he called “a quiet moment,” suggested that the Vice President get in touch with the President and confirm the engage order. Bolten told us he wanted to make sure the President was told that the Vice President had executed the order. He said he had not heard any prior discussion on the subject with the President.

The Vice President was logged calling the President at 10:18 for a two minute conversation that obtained the confirmation. On Air Force One, the President’s press secretary was taking notes; Ari Fleischer recorded that at 10:20, the President told him that he had authorized a shootdown of aircraft if necessary.

Minutes went by and word arrived of an aircraft down in Pennsylvania.

Those in the shelter wondered if the aircraft had been shot down pursuant to this authorization.
