F__k That - The Disappearance of Frederick Valentich

Promo for The Final TraceFrederick Valentich was an Australian pilot who disappeared while on a 125-nautical-mile (232 km) flight in a Cessna 182L light aircraft, registered VH-DSJ, over Bass Strait. On the evening of Saturday 21 October 1978, twenty-year-old Valentich informed Melbourne air traffic control that he was being accompanied by an aircraft about 1,000 feet (300 m) above him and that his engine had begun running roughly, before finally reporting: "It's not an aircraft."
