On April 6th, 1966, flocks of students and staff witnessed a round-humped object with a flat base hovering over school grounds for ~20 minutes while circled by civilian aircraft. Some witnesses recounted the object having hovered between trees, shuffling up and down until the object finally lifted off and vanished. Skeptics believed the object had been misidentified and was an errant high-altitude balloon used to monitor radiation levels. This is known to be one of Australias most compelling cases.
