While some accounts of this event state that there was one craft, Australian UFO researcher, Bill Chalker’s investigation concluded that there were actually two craft involved. After watching the strange disc-shaped objects descend, students and teachers excitedly ran from the school and across the oval for a closer look, with several students actually approaching the craft in the field after climbing over a fence. Then, around 20 minutes after they had descended from the sky, the UFOs took off at great speed. One headed west, the other appeared to orbit a small plane before shooting off to the south. Patches of burnt ground were found at the claimed landing site. In all, over 200 students and teachers of Westall High School witnessed the event making this one of Australia’s most compelling UFO sightings. In an interesting footnote to the Westall UFO mystery, an interview with one of the witnesses, Joy Tighe, who recounted the event to a Channel 9 news reporter, was, according to the network, later removed from the station’s archive and never returned. Naturally, there has been much written about the Westall UFO case, you can find out more at AboveTopSecret’s Westall UFO forum. There is also a documentary you can view Westall 1966: A Suburban UFO Mystery. And Bill Chalker’s The Oz Files includes his interview with one of the many witnesses to the event, and also describes an earlier encounter with a similar object in the same area.
