Twin Otter 13807 was searching for another SAR aircraft (civilian) that had gone down looking for an overdue light plane. The aircraft flew into the side of a mountain, killing all on board: pilot Capt. Ted Katz, co-pilot Capt. Wayne Plumbtree, Flight Engineer Brian Burkett and five observers.
The accident was caused by a freak optical illusion. Color of rocks in mountain combined with sun angle at the time of the crash to make a large ledge, impossible to see.
