The aircraft departed Dibrugarh-Mohanbari Airport bound for Kunming. En route, while cruising in the region of Sookerating at 1418LT, the crew contacted ground to obtain a weather briefing for Kunming Airport. This was the last radio transmission. The aircraft crashed in unknown circumstances somewhere between Sookerating and Kunming, most probably in the mountains of the Assam State. No trace was ever found.
Crew (1st TPG):
2nd Lt Howard G. Bushey,
1st Lt Robert D. Coker,
S/Sgt Walter A. Hynes.

Crashed on landing. No casualties.

One hour into the flight, the crew encountered bad weather and severe icing conditions. While the aircraft continued to lose altitude, pilots realized they were facing a mountain. The captain made a sharp turn to the right when the left wing hit a rocky peak. The aircraft stalled and crashed at an altitude of more than 4,000 metres above MSL. Despite their injuries, both pilots managed to escape and to find help. However, the aircraft was destroyed and the radio navigator was killed.

The aircraft christened 'Pregnant Swan' most probably crashed in a mountainous region of Assam while on a flight from Kunming to Chabua. No trace of the aircraft nor the crew was found.

En route from Kunming to Dinjan, while carrying a load of tin bars, the crew encountered poor weather conditions with low visibility due to heavy snow falls and turbulence. The aircraft disappeared and maybe crashed in the region of Fort Hertz. No trace of the wreckage nor the crew was found.

The crew was performing a cargo flight from Kunming to Dinjan with a load of tungsten on board. Due to the presence of Japanese forces along the normal route, the crew decided to divert and to follow another route passing over the Pianma Pass. In low visibility due to snow falls, the captain reduced his altitude to maintain a visual contact with the ground when the aircraft hit tree tops and crashed in a wooded area located near the Pianma Pass, at the border between China and Burma. All three crew were killed. Some debris of the aircraft were found by hikers in October 1996.

A load of ammunition and fuel drums was dropped in Kunming. On the return flight to Dinjan, Assam, the aircraft hit the slope of a mountain and disappeared. SAR operations did not find any trace of the aircraft nor the crew. Eventually, the wreckage was found in 2011 on the slope of a 13,400 feet high mountain located 15 km northwest of Dali.

En route, the crew spotted a group of Japanese fighters and decided to divert quickly to the small airport of Changyi. After landing, the twin engine aircraft named 'Chungking' was attacked by the Japanese fighters and the left wing caught fire and exploded. The captain, the stewardess and seven passengers were killed while all other occupants were injured.

While on a connection flight within China, the three engine aircraft was shot down by the pilot of a Japanese fighter. The crew attempted an emergency landing when the airplane named 'Heinrich Mathy' crashed near Kunming. Both pilots were killed while both passengers were injured.
