On a summer morning in July 1984, 34-year-old pilot Gordon Keith Newstrom departed Anchorage in a white Cessna 401B with green and gold trim, registration N7984Q, with four passengers — Gerald Dalrymple, Jack Dickey, Donald Gabbert, and John Murphy — bound for Cantwell. The flight, an inspection trip for Newberry Alaska Inc., lifted at 7:31 AM and communications stopped shortly after takeoff. The plane never arrived and vanished into the Alaska Range.

Searches turned up no wreckage or remains. Weather briefings that morning warned of occasional marginal conditions along the route and Cantwell was under Instrument Flight Rules, but the official investigation could not determine the reason for the occurrence. The NTSB’s final classification lists fatal injuries for all five occupants. Gordon Newstrom’s father spent seven years flying the wilderness seeking the aircraft without success.

The exact circumstances of that flight remain unknown. Does anyone have memories, photos, or information about that July 1984 flight or the men aboard that could help fill the gaps?
