The crew was engaged in a training mission when an engine failed in flight. The pilot in command elected to make an emergency landing and reduced his altitude when the aircraft hit power lines and crashed in a pasture. All four crew members were unhurt while the aircraft was written off.

Crashed in Lowry AFB while landing in poor weather conditions. At least one crew member was killed in the accident.

Shortly after takeoff from Minneapolis-St Paul-Wold-Chamberlain Field Airport, while climbing in poor weather conditions, the captain decided to attempt an emergency landing for unknown reason. The aircraft crash landed in a field and came to rest with the left engine on fire. All 31 occupants were able to vacate the cabin and there were no injuries. The aircraft christened 'The Haylift Express' was damaged beyond repair. All passengers were members of the Reserve Officers Training Corps (ROTC) of the University of Minnesota.

An in flight fire forced the crew to attempt an emergency landing. The aircraft belly landed in a field located in Hartsville, slid for several yards and came to rest in flames. All four crew members escaped without injuries while the aircraft was destroyed by fire.

Control was lost in flight following a structural failure. The aircraft dove into the ground and crashed in a field located 2.5 miles east of Leon Springs. Both pilots were killed.

The crew was performing a flight from Clark AFB in Manila to Tachikawa AFB in Tokyo with an intermediate stop in Kadena AFB, Okinawa. On the second leg, while approaching Tachikawa AFB by night, the crew encountered poor weather conditions with low clouds and rain falls. While descending to an altitude of 5,000 feet, the four engine aircraft hit the slope of the Mt Hirugatake (1,279 meters high) located 34 km southwest of the Tachikawa AFB. The aircraft was destroyed by impact forces and all 35 occupants were killed.

Three minutes after takeoff from runway 08 at Kirtland AFB, while in initial climb, the heavy bomber went out of control and crashed in a huge explosion on a mountain slope located near Sandia, about 5,7 miles east of the airbase. The aircraft was totally destroyed and all 13 crew members were killed. Detonators were installed in the bomb on board the aircraft. The bomb case was demolished ans some high explosive (HE) material burned in the gasoline fire. Other pieces of unburned HE were scattered throughout the wreckage. Four spare detonators in their carrying case were recovered undamaged. There were no contamination or recovery problems. The recovered components of the weapon were returned to the Atomic Energy Commission. Both the weapon and the capsule of nuclear material were on board the aircraft but the capsule was not inserted for safety reasons.

Following an engine fire or explosion in flight, the crew was forced to divert to Fairfax Field for an emergency landing. The aircraft belly landed and came to rest. There were no casualties.
