The crew was engaged in a training flight from Lincoln and the mission consisted in a test of the embarked compass system. While flying in the region of Kansas City, the crew encountered technical problems with the compass and attempted an emergency landing when the aircraft hit tree tops, electric and telephone cables before crashing onto a house located in Merriam, in the suburb of Kansas City. Three crew members were killed while three others were injured. Four people on the ground were injured as well.

The aircraft was lost without trace (maybe in the region of Tezpur) while performing a flight from Tezpur to Kunming. No trace of the aircraft nor the crew was found.

Crashed in unknown circumstances some 48 km west of Loshan. All seven occupants were killed.

En route, crew encountered poor weather conditions with severe icing and strong winds. The aircraft deviated from the prescribed track and in low visibility, hit a mountain slope located in the region of Lhasa, Tibet. SAR operations were suspended after few days as no trace of the aircraft was found. The wreckage was eventually spotted in July 1994 at the altitude of 14,000 feet in a glacier.

The crew was performing a flight from Jorhat, India, to the US Airbase of Yangkai located some 33 miles northeast of Kunming, Yunnan, China. En route, pilots encountered poor weather conditions and in an unclear situation, a crew member was able to bail out before the aircraft crashed in a mountainous region located in the northwest part of China. Three crew were killed while the fourth was rescued.

Shortly after take off, while in initial climb by night, the four-engine aircraft went out of control and crashed in a huge explosion 4 km north of the airfield. All ten occupants were killed.

The airplane caught fire in flight and was abandoned by the crew and crashed in the region of Kunming. All 15 occupants parachuted to safety.

The airplane departed West Palm Beach Airport at 0030LT on a supply flight to Georgetown, Ascension Island. While overflying the Bahamas at the assigned altitude of 9,000 feet about 90 miles east of Florida, the crew encountered an unexpected situation. The airplane became unstable and severe vibrations were noted in the tail, the stabs and the control column. In such situation, the captain decided to return to West Palm Beach but approaching Florida, the on-board situation worsened and the crew decided to abandon the aircraft and bailed out. Six crew were found alive about 10 miles east of Hollywood, Florida, while two other occupants were never found. With the autopilot engaged, the aircraft continued to the west, overflew the Gulf of Mexico for about 2,000 km and eventually came down, short of fuel, on Cerro Viejo near General Zaragoza, Nuevo León.
