The Vanishing Aircraft Swallowed By A UFO | Before It's News: "People go missing all the time. There's a whole list of well known people who have disappeared without trace but not quite so many who may have been intercepted by a UFO.
One such well known case is that of Frederick Valentich, an Australian amateur pilot. He disappeared on October 21 1978 and he or his aircraft have never been found.
All the action took place after departing Morrabin Airport, Melbourne. Valentich was on a flight across the Bass Strait to King Island in his blue and white Cessna 182 aircraft.
The flight appeared to be going okay for the best part of an hour when at 7:06pm Valentich radioed aircraft control reporting that there was a large aircraft flying within sight of him at 5000 feet. His call sign was Delta Sierra Juliet (DSJ) and this is how the radio exchanges went. These were punctuated with curious metallic noises."
