United Airlines flight dispatcher Ed Ballinger is informed that Flight 93, which he is responsible for monitoring, is heading for Washington, DC. At the United Airlines System Operations Control (SOC) center, near Chicago, dispatch manager Mike Barber tells Ballinger that Flight 93 is “off track, heading for DC.” The aircraft has just reversed course (see (9:36 a.m.) September 11, 2001) and, having learned that it is not responding to FAA communications (see (9:30 a.m.) September 11, 2001), officials at United Airlines headquarters now believe it has been hijacked.
