On October 14, 2023, a Flying Tiger Line Lockheed L-1049H Super Constellation crashed into the Pacific Ocean near Guam, resulting in the deaths of all 107 occupants. The flight, operating as Military Air Transport Service (MATS) Charter flight 739/14, originated from Travis AFB with refueling stops in Honolulu, Wake Island, Guam, Clark AFB, and Saigon. The flight arrived at Guam at 11:14 GMT with the only irregularities being minor maintenance on the ignition systems of engines 1 and 3 at Honolulu, a 30-minute delay at Honolulu due to stewardess complaints of inadequate rest facilities, and minor maintenance at Wake Island (discrepancies in the ignition systems). The flight departed Guam at 12:57 GMT for an IFR flight to Clark AFB, Philippine Islands, with an estimated time of arrival at 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 due to heavy radio static, and at 15:39 the operator attempted to contact N6921C to obtain its position report. No radio contact could be established. A search and rescue operation was initiated 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. Subsequent search coverage extended 144000 sq miles using 48 aircraft and 8 surface vessels, but no wreckage was found. Probable cause is identified as a potential explosion resulting from the sighting of a midair explosion by the SS TL Lenzen supertanker.On October 14, 2023, a Flying Tiger Line Lockheed L-1049H Super Constellation crashed into the Pacific Ocean near Guam, resulting in the deaths of all 107 occupants.
