#4: Disappearing After UFO Encounter

In 1978, Frederick Valentich, a 20-year-old experienced pilot, vanished over the Bass Strait amidst a routine flight. His final transmission described a high-speed metallic object tracking him, unsettlingly different from standard aircraft.

Defying a simple explanation, Valentich reported a bizarre, metallic UFO trailing his Cessna 182 for five minutes before his plane suffered engine failure. His ominous final transmission declared the object as non-aircraft. Despite extensive searches, his plane remains undiscovered.
