Fairchild C-123 Provider

Crashed on final approach to Gila Bend Airport, killing all four crew members.

Few minutes after takeoff from Đà Nẵng Airport, while climbing, the airplane struck the slope of a mountain and was destroyed. All 38 occupants, 36 South-Vietnamese soldiers and two Americans, were killed. The aircraft was engaged in a secret mission at the time of the accident.

The crew departed Nha Trang on an ammunition supply mission. While overflying Vietnam, the airplane was struck by enemy fire, went out of control and eventually crashed in an uninhabited area located in Phum Dak Dam, in south of Cambodia, bear the border with Vietnam. The aircraft was totally destroyed and all eight crew members were killed.

The airplane was returning to Gia Vuc following a flare dropping mission. After touchdown, it went out of control, veered of runway and eventually collided with barracks. All four crew members were unhurt while the aircraft was damaged beyond repair.

The crew was engaged in a local training at Hurlburt Field AFB and was completing touch and go manoeuvres. On final approach, the airplane went out of control and crashed half a mile short of runway threshold. Four crew members were killed and four others were injured.

Shortly after takeoff from Valdez Airport, while climbing by night and in heavy snow falls, the airplane went into a nose-down attitude then plunged into the sea about a mile off shore. All six crew members were killed. They were conducting a local training flight on behalf of the Air National Guard.

The aircraft was engaged in a flare drop mission and was carrying four Vietnamese observers and four crew members. While cruising at low height, the airplane was shot down by enemy fire and crashed about 104 km south of Saigon. All eight occupants were killed.
Crew:

Cpt Gordon Richard Brown,

S/Sgt Walter Kenneth Morris.

The crew was engaged in an airlift supply mission. Upon landing on a remote airfield, the nose gear collapsed. The airplane came to rest and was abandoned. All four crew members were unhurt.

After taking off from the airfield at Nakhon Phanom the pilot attempted to snare a red flag on top of a flag pole. Apparently, this trick had been attempted before by other C-123 crew based in Thailand. During the second attempt the left wing hit a house and the aircraft crashed killing all three crew and two Thai civilians on the ground. Nakhon Phanom Airfield in north-eastern Thailand, close to the border with Laos, was still under construction when the accident happened. It is possible that the C-123s were bringing in construction equipment or supplies.
