While in a commando mission along the Ho Chi Minh Trail, the airplane was hit by enemy fire. A fire erupted on the left wing root and the crew was unable to extinguish the fire. A crew member (S/Sgt Eugene Fields) was able to bail out and was later recovered uninjured while the aircraft dove into the ground and crashed, killing all 10 other occupants.

The airplane departed McDill AFB, Florida, on a flight to Langley AFB. After a technical stop at Shaw AFB located in Sumter, the crew continued bound to the north. About 20 minutes prior to its arrival at Langley AFB, while in cruising level, the airplane collided with a USAF Douglas TA-4F Skyhawk. Both aircraft went out of control, entered a dive and crashed in the region of Weldon. All six crew members on both aircraft were killed.

Shortly after takeoff from Kadena AFB, while en route to Vietnam, the crew informed ground that two engines failed and was initiating a return. Shortly later, the airplane went out of control and crashed into the ocean some 24 km southeast of Kadena AFB. All 11 occupants were killed.

For unknown reason, the pilot continued the approach at an insufficient altitude until the aircraft struck the slope of Mt Phou Bai at an altitude of 7,500 feet. All six crew members were killed.

While conducting a low level dropping mission (ammunitions), the airplane was shot down by enemy fire and crashed. All three crew members were killed.

The B52 of the 28th Bomb Wing at Ellsworth AFB, South Dakota, crashed and was destroyed after a landing accident. It caught fire and skidded into a brick storage building containing six 25,000 gallon tanks (150,000 total) of jet fuel. The firemen did a fantastic job in saving the crew member (the navigator) who was trapped inside the nose section that had broken off for almost an hour before being freed. The fire truck rammed the gun turret, breaking it off and freeing the tail gunner. Crew:
Cpt Wesley G. Swann, pilot,
Cpt Gary C. Christensen, copilot,

The pilot instructor was sole on board the aircraft and was apparently not authorized to perform such flight. The accident occurred in unknown circumstances near Torrejón Airbase located near Madrid. The airplane was destroyed and the pilot was killed.

On final approach to Đà Nẵng, both engines failed. The airplane stalled and crashed 2 km short of runway threshold. All 10 occupants were injured and the aircraft was destroyed. The crew was returning to Đà Nẵng following a reconnaissance mission.
