After touchdown at Vũng Tàu Airport, the twin engine airplane went out of control, veered off runway and collided with two parked aircraft, a Grumman OV-1 registered 61-2712 and an U-6A Beaver registered 53-7397. All three airplanes were destroyed and all eight occupants on board the TC-45 were seriously injured.

The airplane suffered an engine failure in flight. Control was lost and it crashed in an open field located in Phước Tuy. 1st Lt James Fielding Wohrer was killed while four others were injured.

On final approach top Katum Special Forces Camp, at an altitude of 3,000 feet, the airplane was hit in the port wing by a quad .50 calibre radar-directed anti-aircraft gun causing a fire an engine failure. The aircraft went out of control, dove into the ground and crashed few km short of runway. All six crew members were killed.

The aircraft was completing a flight to Katum, carrying a load of construction equipment. On final approach, the airplane was hit by enemy fire. After touchdown, when the propellers went into reverse pitch, the fuel was sucked up into the engines and ignited. The aircraft veered off runway to the right and came to rest in flames. All five crew members escaped uninjured while the aircraft was partially destroyed by fire.

At 12:05 on 18 May 1969 the Marine Corps KC-130F tanker departed Da Nang Air Base on a routine operational tanker mission. The aircraft continued to the Hue Phu Bai Area for the in-flight refueling mission. The tanker had departed its assigned track by and was proceeding toward the ocean before turning southeast to Da Nang. The KC-130F proceeded southbound for the Hue Phu Bai airfield area while refueling two US Marine Corps McDonnell F-4B Phantom fighter aircraft (152270 and 151450). All three aircraft were descending in a "tobogganing" maneuver while heading southbound in the vicinity of the South Vietnam Coastline. At the same time a separate USMC F-4B Phantom (151001) was heading in a generally westbound direction toward the Hue Phu Bai military area. The two aircraft approached each other nearly head on with a closing rate of approximately 700 knots true airspeed. The initial impact by the F-4B was in the vicinity of the number four engine and the starboard refueling pod on the KC-130F. The radome on the F-4B cleared the propeller on the number four engine as the cockpit initially impacted with it. The single F-4B crashed and the pilot and RIO died instantly. The KC-130F crashed into the sea. One of the refueling F-4B's was severely damaged from the initial crash debris. Phantom 151450 plugged into the starboard drogue, was sprayed with fuel and apparently ingested an undetermined amount of debris into both engines. The F-4B aircraft flipped uncontrollably to an inverted position while the drogue and a portion of the hose remained attached to the aircraft. Its engines could not sustain power and the fighter crashed at sea. Both crew members successfully ejected and were recovered. The second refueling F-4B fighter, 152270 was plugged into the port refueling drogue and sustained limited damage in the form of two small holes in the port aileron and a 1/2 inch hole in the starboard wingtip. The pilot observed the spinning tanker, and when it was apparent he could render no further assistance returned to Chu Lai Air Base without further incident.

On final approach to Lộc Ninh, the airplane was hit by ground fire. Upon touchdown, several tires burst. The airplane went out of control, veered off runway and came to rest in flames. All three crew members escaped uninjured while the aircraft was destroyed by a post crash fire.

For unknown reason, the airplane landed on its left main gear first on runway 07 at Phan Thiêt Airport. After touchdown, control was lost. The airplane veered off runway to the left, struck an earth mound and came to rest. All 31 occupants escaped uninjured while the aircraft was damaged beyond repair.

While descending to Huế-Phú Bài Airport, the crew encountered poor weather conditions with limited visibility. Too low, the twin engine airplane struck the slope of Mt Loc Thuy located about 45 km southeast of Huế Airport. All five occupants were killed.
