Russell John Santema, 21, vanished on November 21, 1977, while a passenger on a plane reported overdue between Point Hope and Lisburne Air Force Station in the Northwest Arctic Borough of Alaska. He was a white male, about 6 feet tall, 165 pounds, with brown hair and blue eyes, and was dressed for the arctic in a snow suit, boots, and gloves.

Searchers found a large hole in the ice roughly three miles off the coast north of Kivalina, an opening consistent with an airplane breaking through the frozen surface, but no wreckage or occupants were recovered. The Alaska State Troopers investigated, and the circumstances remain unresolved with no further evidence reported.

Does anyone have information about the flight, its route, or searches conducted in that area in late 1977?
