United States Air Force - USAF (since 1947)

On final approach to Sông Bé Airfield, one of the engine failed for unknown reason. The airplane stalled and crashed in flames short of runway. All seven crew members escaped while the aircraft was destroyed.

Shortly after takeoff from Khâm Đức Airfield, while in initial climb, the aircraft was shot down by North-Vietnamese soldiers who were conducting an assault of the airbase. The aircraft went out of control and crashed in a huge explosion some 4 km east of the airfield. All 155 occupants, South-Vietnamese soldiers with their wife and children, were killed. Up to date, this was the worst crash by the USAF and the worst in Vietnam.
Crew:
Maj Bernard Ludwig Bucher,
1st Lt Stephan Craig Moreland,
S/Sgt Frank Monroe Hepler,
A1C George Wendell Long,
Maj John Lee McElroy,
Cpt Warren Robert Orr (was among the passenger).

On approach to Khâm Đức Airfield, the aircraft was hit by small artillery and hydraulic systems failed. After touch down, the aircraft was uncontrollable and veered off runway before hitting a parked helicopter. All five crewmen were unhurt but the aircraft was later intentionally destroyed. Crew, from the 21st squadron, was flying to Khâm Đức to evacuate troops on an emergency evacuation process of the camp.
Crew:
Captain Delmore, pilot,
Joe Donahue, copilot.
Thanks to Bill Schneider from the Khâm Đức Group, who added the following comment: the aircraft was guided off the runway on purpose by superior flying skills. It did not catch on fire at that time but was destroyed for good by USAF fighters that destroyed all remaining assets on the ground, including the SF Camp, engineer equipment and anything that could be of any value to the North Vietnam Army. Delmore's crew was picked up just a few minutes later by a USMC CH-46 helicopter.

Shortly after takeoff from Phù Cát Airfield, while in initial climb, the crew reported an engine failure when the airplane stalled and crashed few dozen yards from the runway end. All five occupants were rescued while the aircraft was destroyed.

The gunship was engaged in an aerial attack from Phu Cat when it was shot down by enemy fire in the region of Pleiku. All seven occupants were killed.

The gunship was engaged in an aerial attack from Phù Cát when it was shot down by enemy fire in the region of Pleiku. Six crew members survived while three others were killed. Those killed were Cpt Donald Lewis Merry, Maj Richard William +1. Wackerfuss.

Several C-130 Hercules transport planes were used to fly supply runs to an airstrip at A Loui. The aircraft approached under low clouds, airdropping the supplies from the rear ramp. Several aircraft were hit by enemy ground fire. The 21st supply aircraft was hit by .50 calibre and 37 mm ground fire. A fire erupted in the cargo hold and the crew attempted to jettison the burning load while the pilot attempted a forced landing on the airstrip. The airplane struck trees, crashed and burst into flames. All eight occupants were killed, among them two photographs.

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.

The crew was completing a flight from Kadena to Bunard Camp located 80 km north of Biên Hòa. On short final, the aircraft encountered turbulences caused by the rotor of a USAF helicopter and control was lost. The airplane landed hard and came to rest. All five crew members were unhurt but the aircraft was considered as damaged beyond repair.

After landing at Khe Sanh Airport, the airplane went out of control, veered off runway to the left then collided with several vehicles (trucks) and came to rest in flames. All eight occupants were injured and the passenger died from his injuries few days later.
