History has seen its fair share of aircraft, and even boats, disappearing into the great abyss that is our mighty oceans. So it wouldn't be surprising to hear that on October 21, 1978, a Cessna 182 light aircraft piloted by Australian Frederick Valentich pulled a Houdini and disappeared right the out of thin air.
On 21 October 1978 of 20-year-old Frederick Valentich while piloting a Cessna 182L light aircraft over Bass Strait in Australia. He intended to land at King Island to pick up three or four friends and return to Moorabbin Airport.
During the 127-mile (235 km) flight, Valentich advised Melbourne air traffic control that he was being accompanied by an aircraft about 1,000 feet (300 m) above him. He described some unusual actions and features of the aircraft, saying that his engine had begun running roughly, and finally reported that the "strange aircraft is hovering on top of me again. It is hovering and it's not an aircraft."
Valentich and his aircraft were never found, and an Australian Department of Transport investigation concluded that the reason for the disappearance could not be determined.
Belated reports of a UFO sighting in Australia on the night of the disappearance led Ken Williams, a spokesman for the Department of Transport, to tell Associated Press that "it's funny all these people ringing up with UFO reports well after Valentich's disappearance."
