A little known UFO incident in Melbourne, Victoria, Australia. occurred in 1966. Around 11:00 am, for about 20 minutes, more than 200 students and teachers at two Victorian state schools allegedly witnessed an unexplained flying object which descended into a nearby open wild grass field.
One child who ran to the landed craft to see, came back screaming. Her name was Tonya. She was taken away in an ambulance never to be seen again by anyone. The door to her house was soon after answered by an english speaking woman who claimed Tonya never lived there.
Four days before this incident, these photographs were taken:
