William Bill Robideau, a 38-year-old pilot, vanished on February 1, 1983, while flying a green and white Bellanca Scout on skis from Melozi Hot Springs to Fairbanks. Two passengers, 29-year-old Kenneth Erlewine and 30-year-old Susan Edmondson, were aboard. The plane was registered N8639V and failed to arrive in Fairbanks as scheduled.

Authorities and fellow pilots mounted searches along the planned route, but no wreckage, bodies, or other evidence were ever found. William was reportedly dressed in brown Carhartts, a coat, a down vest, and insulated bean boots. Without any physical trace, the circumstances of the flight remain unknown and the disappearance unsolved.

Did anyone in the area at the time recall flights or sightings along that route on February 1, 1983?
