The heavy bomber aircraft departed Ubon Ratchathani Airport on a mission over Laos and Vietnam. Few minutes after takeoff, while cruising in stormy weather, the airplane was hit by lightning. Several instruments went out of service and shortly later, the left wing caught fire. The airplane went out of control and entered a dive during which a crew member was able to eject safely. He was later recovered and evacuated. Unfortunately, all five other occupants were killed.

The twin engine airplane was performing a liaison flight from Dijon-Longvic AFB to Romilly-sur-Seine on behalf of the 2nd Squadron. Upon arrival, the airplane landed on its belly, slid for dozen meters and came to rest. All five occupants escaped uninjured while the aircraft registered 141 (2-HK) was damaged beyond repair.

After landing on Lake Donuzlav, the seaplane hit a floating object, went out of control and sank. Three crew members were killed while a fourth occupant was rescued.

Crashed in unknown circumstances into the sea. The crew fate remains unknown.

Prior to departure from Bardufoss to Stokmarknes, the crew was informed about the poor weather conditions en route and the captain was instructed to continue directly to Bodø. Despite these instructions, he decided after takeoff to fly to Stokmarknes. While in cruising altitude, the crew encountered poor weather conditions with low clouds, fog and rain falls when the airplane struck the slope of Mt Lille Tussen (800 meters high) located on the Grytøya Island, about 75 km northeast of the Stokmarknes-Skagen Airport. The wreckage was found 20 meters below the summit and all 17 occupants were killed.

The crew was engaged in a military mission to Vietnam and departed Andersen Air Base in Guam by night. While climbing in poor weather conditions, the airplane became unstable. The pilot-in-command elected to stabilize the airplane making a level off but eventually, the crew decided to abandon the aircraft and bailed out. Out of control, the aircraft crashed into the sea and was destroyed. Few hours later, five crew members were found and evacuated. Unfortunately, a six occupant (Lt Col James Lloyd Vaughan) was missing. His dead body was found 42 days later on a beach on Yap Island.

While flying over the Irish Sea on a liaison flight, all four engines stopped simultaneously. The crew reduced his altitude and ditched the aircraft. All 11 occupants were quickly rescued and the aircraft was later recovered. It was written off.

The airplane departed Ubon Ratchathani Air Base in Thailand on a night armed reconnaissance mission to attack elite NVA forces known to be infiltrating from Laos into South Vietnam along the Ho Chi Minh Trail. While making a second low pass over the target area, the airplane's n°3 engine was hit by a Strela SA-7 missile. The airplane went out of control and crashed in flames in the A Shau Valley. 12 crew members were killed while three others were rescued.
