While on a cargo flight from Detroit to Kansas City, the C-46 collided with a private Piper Aztec registered N5628Y. Following the collision, both aircraft went out of control, dove into the ground and crashed in an open field located in Columbia City. Both pilots on board the C-46 and the pilot of the Aztec were killed.

Crashed in unknown circumstances while completing a flight from Santiago to Antofagasta. The airplane crashed in a mountainous area, killing both pilots.

The crew departed RAF Lindholme on a training mission. While in cruising altitude, the airplane collided with a private Cessna 337 registered G-ATJO. The Cessna went out of control and crashed in a field, killing its pilot, sole on board. Following the collision, three cadets on board the Varsity bailed out and the captain attempted an emergency landing in a field. Six crew members were found alive while one of the cadet who bailed was killed as his parachute was not properly fastened. The aircraft was written off.

The pilot was conducting a ferry flight out from Memphis-Metropolitan Airport. While in cruising altitude, the airplane entered an uncontrolled descent. Due to overload failure, several parts of the airplane separated and it eventually crashed in an open field located near South Haven. The pilot, sole on board, was killed.

The aircraft took-off from Hatfield at 1652 hours to carry out the first of a series of production test flights for the purpose of qualifying for a Series Certificate of Airworthiness. The schedule for the flight called for stalling tests should the aircraft and the flight conditions be suitable. After take-off the aircraft climbed towards the north-east and at about 1830 hours, after completing the greater part of the flight test schedule, the stalling tests were begun. Three approaches to the stall were made in order to check the aircraft's stall warning and stall recovery systems and the flight engineer's log shows that with the aircraft in the landing configuration the stick shaker operated at 102 kt and the stall recovery system at 93 kt. The fourth stalling run was made at a height of 11 600 ft with the aircraft still in the landing configuration but, in accordance with the requirements of the test schedule, the stall warning and stall recovery systems had been made inoperative. Radio telephony communication with the aircraft consisted only of routine 11 messages until at 1834 hours when the pilot-in-command reported We are in a superstall at the moment". This was the last radiocommunication received. At about this time the aircraft was seen over Felthorpe flying very slowly heading south-west at about 10 000 ft. The nose was seen to go up 30 to 40 degrees and the aircraft began to turn to port; the starboard wing then dropped sharply and, following a short burst of engine power, the aircraft went into a flat spin to starboard. The spin continued, the aircraft turning once every 6 to 8 seconds until it reached the ground about a minute and a half later. All four crew members were killed.

While operating a reconnaissance mission out from Ubon over the Khammouane Province of Laos, the airplane was seen to crash in flames near Ban Phakat. All six crew members were killed.
