The aircraft was attempting to land at Tuy Hòa Airport under a very low cloud base when it was hit by ground fire 8 km south of the airbase and crashed killing all five crew members. The airplane, based at Nha Trang, was bringing in a load of 13 tons of aviation fuel and it was 1st Lt Smith's first mission as aircraft commander. Enemy action was never actually confirmed to have caused the loss of this aircraft which may simply have flown into high ground in poor visibility. For some reason the remains of 1st Lt Wax were not recovered and identified until December 1996.
