Eastern Air Lines Flight 401
Eastern Air Lines Flight 401 was a Lockheed L-1011 Tristar 1 jet that crashed into the Florida Everglades on the night of December 29, 1972, causing 101 fatalities (77 initial crash survivors, two died shortly afterward). The crash was a result of the flight crew’s failure to recognize a deactivation of the autopilot during their attempt to troubleshoot a malfunction of the landing gear position indicator system. It is believed that fatigue and poor crew resource management (CRM) contributed to the accident.
