On April 6, 1966, students at Westall High School, near Melbourne, Australia, were eyewitnesses to an alleged UFO that passed over the school (during school hours) and then subsequently landed nearby. This case bears striking similarities to the Ariel School encounter case, which also involved school children. Did Westall students really see an extraterrestrial craft pass over their school, and what evidence exists in favor and against this explanation for the anomalous event?
