On the evening of October 21, 1978, 20-year-old pilot Frederick Valentich departed Melbourne's Moorabbin Airport in a Cessna 182, bound for King Island across Bass Strait. At 7:06 PM, he radioed Melbourne air traffic control to ask if there was any known traffic below 5,000 feet. There wasn't. Valentich described a large, unknown craft with four bright lights hovering above him. 'It is not an aircraft,' he said. At 7:12 PM, after reporting that his engine was rough-idling and the object was hovering above him, Valentich fell silent. Seventeen seconds of metallic scraping sounds followed. Then nothing. Neither Frederick Valentich nor his aircraft were ever found.
