The CH-3E with callsign SKYCAP 36 was on an area familiarization flight for a new pilot and delivering cargo to Ubon RTAFB, when it was hit by ground fire flying at about 1000 feet about 20 miles north of their destination. A 12.7mm round destroyed the hydraulic accumulators, knocking out both engines and causing the helicopter to crash upside down and in flames.
The pilot Capt. Alan B. Cheeseman, trainee pilot Capt. George D. Henry, Jr. and flight engineer SSgt Terry D. Reams were killed. Co-pilot Capt. Vic Genez survived with injuries and managed to rescue flight engineer Sgt William L. Ripley from the burning wreckage, but he later died of his burns.
