James O. Madsen, Jr., 26, disappeared on September 17, 1978, when a chartered Cessna 411 twin-engine plane carrying him and two others left King Salmon bound for Kodiak and never arrived. The flight, operated by Viking Air Services, is presumed to have crashed in the Shelikof Strait, but no wreckage, debris, remains, or communications were ever found.

Search and rescue operations scoured the coastline and waters around the strait but were suspended after days with no sign of the aircraft. The National Transportation Safety Board concluded that the probable cause could not be determined because of the absence of physical evidence. The other passengers named in reports are Nekita Katelnikoff and Marion Parker.

The absence of a crash site or recovered remains has left Madsen’s family without closure. Does anyone have information about the flight, the passengers, or sightings in the Shelikof Strait area around September 17, 1978?
