It may safely be concluded that there was no warning of the disaster. This is evident by the lack of any unusual radio messages.

As has been detailed, the fire marks on bodies and on debris were of the type caused exclusively by a flash surface fire, probably both hot and brief, upon impact with the water.

Probable Cause

Because of the lack of physical evidence, the probable cause of this accident is unknown.
