9:05 a.m. September 11, 2001: American Airlines Begins ‘Lockout’ of Flight 77 Information

American Airlines initiates the “lockout” procedure to protect information about Flight 77. This standard procedure acknowledges an emergency on the flight and isolates information about it, so the airline’s top leadership can manage the case. A lockout safeguards information against being altered or released, and protects the identities of the plane’s passengers and crew. FAA air traffic controllers first alerted American Airlines about their loss of contact with Flight 77 at 8:58 (see 8:58 a.m. September 11, 2001), and called the airline again about the flight at 9:02 (see 9:02 a.m. September 11, 2001).
