This document file (NAA: B638, M116/783/1047 PART 1) documents the disappearance of Frederick Valentich and his Cessna 182L aircraft (VH-DSJ) on 21 October 1978 during a flight from Moorabbin to King Island. The file contains official accident reports, internal minutes, correspondence, and a large collection of press cuttings. Valentich, a 20-year-old pilot, reported to Melbourne Flight Service that he was being followed by an unidentified object that was 'hovering' and 'playing a game.' He described the object as having a 'long shape' and 'metallic light.' Shortly after this report, he stated his engine was 'rough idling' and 'coughing,' followed by a 'long metallic noise' before radio contact was lost. An extensive air and sea search was conducted but failed to locate the aircraft. An oil slick was found, but subsequent analysis determined it was marine oil, not aviation fuel. The file includes a 'Human Factors Specialist Report' by B.J. Mahony, which examines Valentich's background, noting his interest in UFOs, his academic struggles, and his desire to become a commercial pilot. The official investigation concluded that the disappearance was an aircraft accident, with suggestions that the pilot may have become disoriented and flown the aircraft inverted, potentially confusing lights from lighthouses with stars. The file also contains numerous press clippings reflecting the public and media fascination with the UFO aspect of the case, as well as internal administrative notes regarding the handling of the file and requests for information.
