63-7878 in C-130 Historical Posted June 5, 2012 At this point in the war, 315th Air Division operated a number of scheduled missions into South Vietnam, mostly from Okinawa, which was a major supply depot. I can't say for certain, but the mission number was probably the mission number for one of those scheduled missions. In 1966 the 314th TCW was involved mostly in missions operating in and out of South Vietnam. The wing did have a rotational mission at Nha Trang but this crew was not on it since they crew rested at Tan Son Nhut. The mission report doesn't say, but they had probably picked up their load at Naha, Okinawa then went to Da Nang and on to Tan Son Nhut for crew rest. Since they hit a mountain in Taiwan, the Vietnam portion has no bearing on the accident. The report says the airplane had been continually off course, which indicates a navigational error.
