Narrative:
Flying Tiger Line Flight 7815/13, operating as Military Air Transport Service (MATS) Charter flight 739/14, originated at Travis AFB with refueling stops at Honolulu, Wake Island, Guam, Clark AFB and was to terminate at Saigon. The flight arrived at Guam at 11:14 GMT with the only irregularities on the way being minor maintenance on the ignition systems of engines no. 1 and 3 at Honolulu, a 30 min delay at Honolulu because of stewardess complaints of inadequate rest facilities aboard, and minor maintenance at Wake Island (discrepancies in the no. 1 and 3 engine ignition systems). The flight departed Guam at 12:57 GMT for an IFR flight to Clark AFB, Philippine Islands with an ETA of 19:16 GMT.
The flight climbed to a cruising altitude of 18000 feet and reported being at position 13 40'N and 140 00'E at 14:22. The crew expected to reach position 14 00'N 135 00'E at 15:30. At 15:33 Guam IFSS was experiencing communication difficulties caused by heavy radio static and at 15:39 the operator attempted to contact N6921C to obtain its position report. No radio contact could be established.
Search and rescue operations were instituted at 19:43. It appeared that at 15:30 GMT (01:30 local time) the crew of the SS TL Lenzen supertanker had sighted a midair explosion from their position at 13 44'N and 134 49'E.
The subsequent search covered 144000 sq miles using 48 aircraft and 8 surface vessels, but nothing was found.

PROBABLE CAUSE: "The Board is unable to determine the probable cause of this accident from the evidence now available."
