After touchdown at Vĩnh Long Airstrip, the crew encountered technical problems. The airplane went out of control, veered off runway and came to rest. All three crew members escaped uninjured while the aircraft was written off.

After touchdown on an airbase located somewhere in South Vietnam, the airplane went out of control, veered off runway and collided with a parked helicopter. There were no casualties but the aircraft was destroyed.

On final approach to Na Khang Airport, the crew failed to realize his altitude was too low when the airplane struck a 50 cm high earth bank located 10 meters short of runway threshold. On impact, the undercarriage were torn off and the aircraft belly landed. All four crew members were uninjured while the aircraft was damaged beyond repair.

The crew was engaged in an aerial attack of a Viêt Cong camp located at Xóm Rach Tàu, at the extreme south coast of South Vietnam. While cruising at low height, the airplane was hit by enemy fire. The left engine and the left wing caught fire and the crew elected to evacuate the area when the airplane went out of control and crashed into the sea few km offshore. All three crew members were killed.

The airplane departed Hultburt Field AFB at 0800LT on a training mission under call sign Moose 09. The assigned mission was a routine SEA serial spray training flight. The formation proceeded to a point 25 nm northwest of Panama City, Florida (the designated spray training area), arriving there at 08:35 CST. At this time a series of simulated defoliation runs were conducted over an open field. At approximately 08:50 CST Aircraft 54-0602 assumed the number three position in a right echelon formation for practice defoliation runs along a series of roads. At the completion of the first run the lead aircraft gave a command to place the aircraft in a "piggy back" formation, then climbed from 150 feet AGL to approximately 300 feet AGL and executed a 270 degree turn to the right. While in this turn the Number Three aircraft contacted the ground in a left wing low position, cartwheeled, immediately caught fire and was destroyed. The instructor pilot, two student pilots, and the flight engineer sustained fatal injuries.

According to the testimony of John R. Young, there was a sudden loss of power. The aircraft came down fast and hard. The captain tried to belly land when the plane broke up below cockpit and became a giant plow. Two occupants (pilot and taskmaster) were fatally injured and other occupants were injured, some seriously. There were few troops and locals on board at the time of the accident.

The airplane was operating over the Ho Chi Minh Trail in southern Laos when its port engine was damaged by AAA near Ban Namchalo. The pilot aborted the mission and carefully made his way back to Nakhon Phanom where he made an emergency landing. All five crew members were uninjured but the aircraft was so badly damaged that it had to be scrapped.

The aircraft was completing a flight from Huế to Khe Sanh, carrying troops and spare parts. On approach, the crew was forced to make a go-around because of the presence of a light aircraft on runway. Shortly later, the airplane was hit by ground fire. The left engine caught fire and the airplane crashed in a dense wooded area located 2 km from the airfield. All 50 occupants were killed, 5 crew members, 44 soldiers and one civilian photographer.

After liftoff from Khe Sanh Airstrip, while in initial climb, the airplane was struck by a mortal shell. The captain decided to land immediately and after touchdown, the airplane went out of control, veered off runway and came to rest in flames. All 10 occupants escaped uninjured while the aircraft was destroyed.
