On September 30, 1974, 31-year-old Robert Bergman left Anchorage aboard a white and red trimmed Grumman Mallard amphibian, registration N2965, with three other men for a seabird survey mission to Kodiak. Also aboard were Robert Johnson, Jay Haddock, and Leonard Boughton. The flight never reached Kodiak and was reported overdue, triggering search and rescue operations.

The aircraft, operated by the Department of the Interior’s Bureau of Land Management Office of Aircraft Services in Anchorage, disappeared over the north Pacific Ocean. The pilot had more than 15,000 hours of flight time and no distress call was received. Despite several days of searching, neither the plane nor its four occupants were found and the investigation could not determine a probable cause because the aircraft was never recovered.

Anyone with information about the flight, its last known route, or the search efforts is asked to come forward.
