On October 21, 1978, 20-year-old Frederick Valentich disappeared during a flight in his Cessna 182L. Frederick was widely described by friends and family as a “flying saucer enthusiast,” and during the doomed flight, he reported being accompanied by an unidentified aircraft.
As Frederick flew over the Bass Strait between Tasmania and mainland Australia, he radioed air traffic control just after 7:00 PM to report that he was being followed by an aircraft. Air traffic control responded, saying there was no known traffic nearby. Valentich described the aircraft as large and illuminated by four bright landing lights. It purportedly passed about 1,000 feet overhead and was moving at very high speed.
Finally, Frederick stated that the UFO was orbiting above him and had a shiny metal surface and a green light. Air traffic control asked him to identify the craft, to which Frederick responded, “It isn’t an aircraft,” before his transmission was interrupted by unidentified noise described as “metallic, scraping sounds.” Contact was lost at this point, and neither Valentich nor his plane were ever seen again.
