The Valentich disappearance describes an event on 21 October 1978 when 20-year-old Frederick Valentich disappeared in unknown circumstances while piloting a Cessna 182L light aircraft over Bass Strait to King Island, Australia.
During a 127 mile training flight, Valentich advised Melbourne air traffic control he "was being buzzed by a UFO with four bright lights" about 1,000 feet (300 m) above him. He made several reports, including that the engine was running roughly, and his last message was "it is not an aircraft."
