On a morning in 1966, students and staff at Westall High School came out for mid-morning recess and reported an object over the school oval. Most accounts describe a silver disc holding low and without sound. One describes a silvery-grey cigar shape that changed form as it moved. Children at nearby Clayton North Primary reported seeing it too. Several accounts have the object descending behind the Grange pine trees into a paddock, where a circle of flattened, radially twisted grass was later found. Light aircraft were reported circling before it accelerated away.
What is on the record
The archive resolves three claimants across three videos and two reporting channels: the science teacher Andrew Greenwood and two collective entries for the students and staff. The tellings themselves put far larger numbers on the day: roughly 300 of about 600 students plus three staff in one account, over 100 students and a science teacher in another, more than 300 schoolchildren and staff in a third. Those are the sources' figures rather than the archive's count. The science teacher Andrew Greenwood recurs across channels.
A second cluster of claims concerns the aftermath. Sources describe military vehicles arriving within about twenty minutes, a teacher's camera confiscated, an assembly at which students were told to forget the event, a news interview cut off, and children threatened with detention. Greenwood is said to have been warned by an Air Force officer and a civilian who told him they would brand him an alcoholic. Officials including Moorabbin Airport and the RAAF are reported to have played the event down.
The gaps are real. The file holds no documents at all, so every claim of an official response rests on recollection. The tellings disagree on shape and on whether one object was seen or three. One account, from a man who was six at the time, describes three spindly grey beings floating from a landed craft and communicating telepathically. It sits in the file as one telling among three.
Why it sits where it does
Westall grades L3: multiple independent claimants describing one connected event across two channels. No government paperwork and no authenticated footage carry it, so it does not climb higher. Its weight comes from the number of separate people placing themselves in the same schoolyard on the same morning. What was over the oval is not resolved here.
