Eastern Air Lines Flight 401 was a Lockheed L-1011-1 Tristar jet that crashed into the Florida Everglades at 11:42 pm December 29, 1972, causing 101 fatalities (99 initial crash fatalities, two died shortly afterward). The Captain, along with one of 2 flight crew members, two of 10 flight attendants and 97 of 163 passengers, died. There were 75 survivors. The crash occurred as a result of the entire flight crew becoming preoccupied with a burnt-out landing gear indicator light, and failing to notice the autopilot had inadvertently been disconnected. As a result, while the flight crew was distracted with the indicator problem, the aircraft gradually lost altitude and crashed.
