10:02 a.m. September 11, 2001: Secret Service Warns Vice President Cheney that Hijackers Are Headed Toward Washington

Vice President Cheney and other leaders now in the White House bunker begin receiving reports from the Secret Service of a presumably hijacked aircraft heading toward Washington. The Secret Service is getting this information about Flight 93 through links to the FAA. However, they are looking at a projected path, not an actual radar return, so they do not realize that the plane crashes minutes later. [9/11 Commission, 6/17/2004]
