The Ghosts of Flight 401
In December of 1972, an Eastern Airlines flight bound for New York crashed into the Everglades after taking off from Miami. The crash was likely caused when the autopilot was accidentally shut off by a while investigating a burned out indicator light. In the years after the tragic crash, sightings were reported of ghostly-looking men on Eastern flights.
The descriptions given of the men sounded very similar to those of the captain and flight engineer of Flight 401. Rumor has it that Eastern Airlines installed good parts from the wrecked plane into other planes in their fleet.
