Détails:
The TWA Lockheed Starliner departed Milan at 16:20 GMT in weather conditions with scattered thunderstorms. Some 12 minutes later the crew reported climbing through 10000 feet. At 16:35 a structural failure occurred, initiated by a wing separation.

PROBABLE CAUSE: "The breaking-up in flight was due to the explosion of the fuel vapours contained in tank No.7, followed immediately by either an explosion of pressure or a further explosion in tank no.6.
In the absence of other significant concrete evidence, taking into account the stormy weather conditions, with frequent electric discharges, existing in the area at the time of the crash, it may be assumed that the explosion of the fuel vapours contained in tank No.7 was set off, through the outlet pipes, by igniting of the gasoline vapours issuing from these pipes as a consequence of static electricity discharges (streamer corona) which developed on the vent outlets."
