Consolidated B-24 Liberator

Shortly after takeoff from Fenton Airport, while climbing, the aircraft stalled and crashed in flames in a wooded area. All 10 crew members were killed.
Crew (380th BG):
Lt Wilfred Grenfell, pilot 9.

The aircraft took off from Sigiriya at 0554LT to carry out a photographic reconnaissance mission off Car Nicobar Island. The aircraft was due over the target at 1100LT and at 1109LT, its crew transmitted its call sign with one 30 second dash. D/F bearings of these transmissions indicate that the aircraft was over the Car Nicobar Island at that time. Since then there has been no further news. It is believed that the Japanese now have a small number of fighters which they operate from the Car Nicobar landing ground, with an adjacent R.D.F. Station whose range is believed to be in the neighborhood of 100 miles. It is presumed that the aircraft was intercepted by enemy fighters and shot down as another aircraft of this Squadron was destroyed by enemy action in the same area on 23rd September 1943.

A formation of four Consolidated Liberator left Fairmont AFB in the afternoon for a training mission. While cruising at an altitude of 20,000 feet, the crew of 42-7657 decided to leave the formation. Crew of the 42-7673 received the order to take the vacant place. During this process, the top of the tail of 42-7657 hit the other aircraft. Out of control, both aircraft dove into the ground and crashed in an open field located near Millingan. While the copilot of 42-7673 bailed out and was later found unhurt, all 17 other occupants on both aircraft were killed.

On landing at Fenton, the aircraft christened 'Gus's Bus' suffered a gear failure and came to rest. All occupants escaped uninjured while the aircraft was damaged beyond repair but later salvaged.

Lost without trace on a flight from Foggia to Catania. Probably crashed into the Tyrrhenian Sea. No trace of the aircraft christened 'Shanghi Lil' nor the crew was ever found.

Shortly after takeoff from Londonderry Airport, the aircraft crashed in the Lough Foyle. Crew fate unknown.

Shortly after a night take off from RAF Saint Mawgan, en route from Florida to RAF Seething, Norfolk, the aircraft stalled and crashed in a field. All 11 crew members were killed.

The aircraft was returning to Canada from the European War Theater with 20 soldiers in permission and a crew of four. After a fuel stop in Gander, the aircraft continued its route to Mont-Joli Airfield. While cruising by night and in snow falls at an altitude of 2,871 feet, the aircraft hit the slope of the Black Mountain (Montagne Noire) located near Saint-Donat, in the Laurentides. SAR operations were conducted for several weeks and 728 reconnaissance flights for a total of 2,438 flying hours were completed without success. No trace of the aircraft nor the crew was found. Eventually, the wreckage was found by hikers on June 26, 1946. In 2015, this accident is still considered as the worst in the RCAF History.

The aircraft left Pocatello Airport at 0551LT on a training mission with 10 crew members on board. The program consisted on an overflight of Klamath Falls, Oregon, Fort Dick, California, then over the Pacific Ocean and eventually Hamilton Field before returning to Pocatello with an arrival scheduled in the evening. The crew contacted ground around 0820LT to confirm they overflew Klamath Falls about one hour earlier and this was the unique radio contact. Nothing further was heard from the aircraft or its crew. As the aircraft did not return to its base, SAR operations were conducted but eventually suspended after few days as no trace of the aircraft nor the crew was found. It is believed that the aircraft may have crashed into the Pacific Ocean, along the Oregon or California coast, but no trace was ever found.
