This is a very creepy UFO story!
"On the night of October 21, 1978 Frederick Valentich radioed into air traffic control in Melborne with some strange news. An unidentified metallic craft was toying with his Cessna as he flew over the Bass Strait en route to King’s Island. No one ever saw him or his aircraft again."
