On October 21, 1978, twenty year old pilot Frederick Valentich disappeared while flying a small aircraft over Bass Strait in Australia. During his final radio conversation, Valentich told air traffic control that an unidentified aircraft appeared to be following him.
This episode examines what Valentich actually reported, the strange final transmission, the search that followed, and the explanations proposed by aviation investigators and researchers. Despite decades of speculation involving unidentified flying objects, no confirmed wreckage has ever established exactly what happened.
Did Valentich become disoriented over the dark ocean, experience an aircraft emergency, or encounter something that investigators have never been able to identify?
