Mysterious Plane Crashes
In this slide show, review a number of aircraft accidents whose definitive causes remain a matter of debate
A four-engine Lockheed 1049H Super like the one seen here failed to arrive at its destination near Manila. Traveling in darkness but in good weather conditions, the plane, operated by The Flying Tiger Line (U.S.), had simply vanished in the Philippine Sea. Its final radio transmission gave no indication of difficulty. A week-long search encompassing 114,000 square miles of ocean failed to turn up any trace of the plane or its 107 passengers, and investigators never determined the cause of the crash.
