The crew departed Saigon on a supply dropping mission to An Loc. While flying at low height and high speed, the airplane was hit by enemy fire. The crew elected to return to Saigon when few minutes later, the right wing caught fire. The captain attempted an emergency landing when the airplane crashed in flames in a swampy area. All five occupants were rescued while the aircraft was destroyed.

Engaged in a military mission on the Ho Chi Minh Trail in Laos, the aircraft was hit by ground fire while flying at an altitude of 7,500 feet. The captain elected to return to his base when the right wing caught fire. All 15 occupants bailed out and abandoned the aircraft that dove into the ground and crashed.

The airplane was engaged in a military operation along the Ho Chi Minh Trail when it was hit by an SA-2 surface to air missile. Out of control, it crashed 16 km southeast of Xepon. All 14 occupants were killed.

A minute after takeoff from Jacksonville AFB, the Hercules collided with a USAF Jet trainer Cessna T-37 Tweet carrying two pilots. The crew was inbound to Jacksonville AFB on a flight from Big Spring-Webb Airbase. Following the collision, both aircraft went out of control and crashed in a field located about 3 miles from the airfield. While both occupants on board the T-37 ejected and survived, all five crew members on board the Hercules were killed.

Navy Hercules 151890 had flown for over three months with a maintenance discrepancy on the number one fuel tank quantity indicator. Before the mishap flight, another attempt was made to repair the solder connections in the cannon plug. Maintenance personnel were unable to satisfactorily complete the repair in the time available before that days flight. They hurriedly reassembled the cannon plug and verbally warned the oncoming flight engineer to leave the number one fuel tank quantity indicator system circuit breaker out to prevent the indicator motor from running and ruining the internal clutch. The aircraft then flew four flights prior to the accident. The verbal warning was passed between flight engineers, except on the fourth flight. While conducting preflight procedures the fourth flight engineer noticed the circuit breaker to be out and reset it. The circuit breaker popped within seconds and was then left out for the flight back to home field. The circuit breaker was reset by an unknown person between the time the aircraft landed and the preflight the next day by the mishap crew. Shortly after takeoff from Patuxent River-NAS, MD (NHK), while climbing through 7500 feet, an explosion occurred in the outboard part of the left wing. A fire erupted. The no. 1 engine was shut down and the extinguisher bottles fired. The crew was unable to control the fire. Control difficulties forced the pilot to carry out a forced landing. An emergency descent was flown at a speed of 270 kts IAS and a forced landing was made in a corn field. After the aircraft came to rest, the fire burned for 36 minutes. The fire continued burning aft and inboard before it was extinguished by a local volunteer fire department.

While taking off at Jacksonville AFB, northeast of Little Rock, the four engine airplane stalled and crashed in flames. A passenger was rescued while 11 other occupants were killed.
