Argosy Air lines Flight 902 was operated by DC-3 N407D. The aircraft was to fly to Cuba to pick up 21 US citrus growers who were there on tour. At 11:24 Flight 902 was cleared to taxi out from the Walkers Cay Jet Center to runway 09L for takeoff. At 11:29 they lifted off from Fort Lauderdale. Weather was fine as the DC-3 reached the cruising altitude of 6000 feet. At 12:25 the flight emerged on Havana’s radar scopes, but the air traffic controller could not read any of the messages from the flight due to static. A high altitude plane relayed the messages to Havana and at 12:35 the messages became loud and clear. Eight minutes later the plane disappeared off the radar screens. The search for wreckage was called off at September 24. PROBABLE CAUSE: “Undetermined.”
