Vice President Dick Cheney phones President Bush and tells him the White House has received a credible threat against Air Force One. [Sammon, 2002, pp. 106-107; Woodward, 2002, pp. 18; CBS News, 9/11/2002] The White House has just received an anonymous phone call in which the caller said the president’s plane would be the next terrorist target (see (10:30 a.m.) September 11, 2001). [Woodward, 2002, pp. 18; 9/11 Commission, 7/24/2004, pp. 554] The caller referred to the plane as “Angel,” which is the Secret Service’s code name for Air Force One. [Fleischer, 2005, pp. 141-142] Details of the call were passed on to government officials, including Cheney, in the Presidential Emergency Operations Center (PEOC) below the White House. [White House, 11/19/2001; Newsweek, 12/30/2001; 9/11 Commission, 7/24/2004, pp. 554]
Cheney Tells Bush about a ‘Credible’ Threat – Cheney now tells Bush: “We’re getting reports of a threat against you. It appears credible,” Major Robert Darling of the White House Military Office, who is with Cheney in the PEOC, will later recall. Cheney says, “We’re scrambling fighter escorts and the Secret Service is taking internal precautions on board Air Force One.” [Darling, 2010, pp. 61] Bush turns to Lieutenant Colonel Thomas Gould, his military aide, and passes on the news, saying, “A call came into the White House switchboard saying, ‘Angel is next.’” Bush then continues talking with Cheney and says, “We’re at war, Dick, and we’re going to find out who did this and we’re going to kick their ass.” [Sammon, 2002, pp. 107; Fleischer, 2005, pp. 141-142]
Pilot Is Told of the Threat and Asks for a Guard at the Cockpit Door – Colonel Mark Tillman, the pilot of Air Force One, is told about the threat. [CBS News, 9/11/2002] Noting that “Angel” is “a classified call sign of Air Force One,” Tillman will comment that “the only people that knew that call sign was us, [the] Secret Service, and the staff.” Therefore, he will say, “for somebody [to] call into the White House and say that Angel was next, that was just incredible.” [US Air Force, 2/29/2012 ] “It was serious before that, but now… no longer is it a time to get the president home,” Tillman will comment. “We actually have to consider everything we say. Everything we do could be intercepted and we have to make sure that no one knows what our position is.” Tillman asks to have an armed guard at his cockpit door. Will Chandler, the chief of security, is therefore summoned to the front of the plane and stands watch at the base of the stairs leading to the cockpit. No one is then allowed up these stairs. Secret Service agents double-check the identity of everyone on the plane, while the crew reviews the emergency evacuation plan. [CBS News, 9/11/2002; Politico Magazine, 9/9/2016]
Threat Influences the Decision to Fly to Nebraska – White House press secretary Ari Fleischer, who is on Air Force One with Bush, will say the threat against the president’s plane is what leads to the decision to take Bush to Offutt Air Force Base in Nebraska (see 2:50 p.m. September 11, 2001) and is also one of the reasons why Bush does not head back to Washington, DC, right away. [White House, 9/12/2001] However, during the afternoon, the Secret Service will determine that the reported threat was unfounded. [9/11 Commission, 7/24/2004, pp. 554] Shortly after Bush learns about the threat, Tillman will be informed that an aircraft that may have been hijacked is heading toward Air Force One (see (10:35 a.m.) September 11, 2001). [CBS News, 9/11/2002; CBS News, 1/17/2009] White House chief of staff Andrew Card will say he in fact learned a threat had been made against Air Force One almost an hour earlier, while he was being driven with Bush to Sarasota-Bradenton International Airport (see (Between 9:35 a.m. and 9:43 a.m.) September 11, 2001).
