Crashed in unknown circumstances few minutes after its takeoff from Goose Bay. SAR operations were conducted but eventually abandoned after few days as no trace of the aircraft nor the crew was found. The wreckage was eventually found in a remote area on June 23, 1953.

While flying northeast of Vancouver, the twin engine aircraft hit a snowy mountain slope located near Widgeon Lake, west of Pitt Lake. Debris were found few days later and all five crewmen were killed.
Crew:
Flying Officer Murray Donald Hill,
Flying Officer Jack Wayne McIntosh,
Flying Officer Ernest Dorph Thygesen, 2.

En route, the heavy bomber was attacked by Major Anatoly Karelin, pilot of a Soviet AF MiG-15 fighter. Ten crew members were able to bail out before the aircraft crashed. A crew member was rescued while three others were killed in the crash. Those killed were:
M/Sgt Cleo A. Brown,
1st Lt Edward R. Francis,
1st Lt Ralph I. Phy.

Crashed in unknown circumstances somewhere in Indochina. Occupant fate remains unknown.

An engine failed in flight, forcing the crew to reduce his altitude and attempting an emergency landing. The twin engine aircraft belly landed in a field located nine miles south of Fredonia. There were no casualties but the aircraft was damaged beyond repair.

The approach to RAF Swinderby was completed in misty conditions. The airplane was too high and passed over the outer marker at an altitude of 750 feet instead of the assigned 600 feet. The pilot increased the rate of descent but could not timely arrest the descent. He advanced the power levers in an attempt to make a go around when the airplane impacted the ground short of the runway threshold. There were no casualties.

The seaplane was engaged in a rescue mission after a USN Neptune was shot down off the Swatow Island. All 11 crew members of the Neptune were transferred on board the USS Halsey Powell. While taking off from rough seas, the airplane went out of control and crashed, killing all nine crew members including the following five USCG personnel:
Ltjg G. W. Stuart,
Alc W. J. Hammond,
Al1 C. R. Tornell,
Ao1 J. R. Bridge,
Ad3 T. W. Miller.

On final approach to Stephenville Airport by night, the four engine aircraft hit the ground and crashed 1,5 km short of runway threshold. A passenger was rescued while 13 other occupants were killed. For unknown reason, the crew was completing the approach at an insufficient altitude.

Both engines failed in flight, forcing the crew to bail out and to abandon the aircraft that dove into the ground and crashed in a field. All six crew members were uninjured.

While cruising at an altitude of 1,500 feet in low visibility due to the night and rain falls, the aircraft collided with a RAF Avro 683 Lancaster GR.3 registered TX270. En route from Luqa to Northolt, the Valetta was carrying 16 passengers and a crew of three. Following the collision, both aircraft crashed into the Mediterranean sea about 46 km southwest of Agrigento. All 26 occupants in both aircraft were killed.
