Just after President Bush authorizes the military to shoot down threatening aircraft, he speaks with Secretary of Defense Donald Rumsfeld about this, according to some accounts. According to the Washington Post, Bush gave the shootdown authorization after taking off on Air Force One (see (Shortly After 9:56 a.m.) September 11, 2001). He then talks “to Rumsfeld to clarify the procedures military pilots should follow in trying to force an unresponsive plane to the ground before opening fire on it. First, pilots would seek to make radio contact with the other plane and tell the pilot to land at a specific location. If that failed, the pilots were to use visual signals. These included having the fighters fly in front of the other plane. If the plane continued heading toward what was seen as a significant target with apparently hostile intent, the US pilot would have the authority to shoot it down.” [Washington Post, 1/27/2002] Journalist and author Bill Sammon will give a similar account, saying that, having spoken with Vice President Dick Cheney soon after Air Force One took off, Bush “then explained the shootdown order to Donald Rumsfeld, who was at the still-burning Pentagon.” [Sammon, 2002, pp. 102] The 9/11 Commission will concur that the “president apparently spoke to Secretary Rumsfeld for the first time… shortly after 10:00.” However, contradicting earlier accounts, it will say, “No one can recall the content of this conversation, but it was a brief call in which the subject of shootdown authority was not discussed” (see (10:00 a.m.-10:30 a.m.) September 11, 2001). According to the Commission, furthermore, the phone call between Bush and Cheney where the president gives the shootdown authorization is not until 10:18 (see 10:18 a.m.-10:20 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 41 and 43] Bush’s senior adviser Karl Rove, who is on Air Force One with the president, will also say this critical call occurs “at about 10:20,” and add that, after it, Bush reports that he has just talked to Rumsfeld as well as Cheney. [MSNBC, 9/11/2002] Rumsfeld will indicate he first learns that shootdown authorization has been given from Cheney rather than Bush, telling the 9/11 Commission that the vice president “informed me of the president’s authorization to shoot down hostile aircraft” over the air threat conference call. [9/11 Commission, 3/23/2004 ] The conversation he is referring to does not occur until 10:39 a.m. (see 10:39 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 43]
