I's an extra-terrestrial mystery worthy of an X-Files investigation.

A Melbourne filmmaker is calling on Monash residents to come forward and unlock the secrets surrounding a UFO sighting in Clayton South 42 years ago.

A 1966 news article


More than 100 people, mostly former Westall High School (now Westall Secondary College) students who witnessed the unidentified "flying saucer" objects from their playground on April 6, 1966, have already spoken out about what they saw.

Documentary director Rosie Jones said she was now searching for any photographic or video evidence of the flying objects and crop circles, which reportedly appeared in the Grange, an area that once bordered the school grounds.

Former students Joy Clarke and Sue Savage are both involved in the documentary and have vivid memories of that bright, autumn day.

"I was in science class and I remember a student came running in and said, 'Mr Greenwood, there's flying saucers near the oval'," Ms Clarke said.

"The sky was perfectly clear and I remember standing there and thinking, 'what am I seeing?'."

The women both recall three objects, one bigger than the others, hovering and flying above the school and the Grange for about 15 minutes before they were "chased" by light aircraft.

Ms Savage said "military-type" men in uniforms showed up.

They ordered the students and teachers back inside and to "keep quiet" about what they saw.

Ms Jones encouraged residents who witnessed the event to phone producer Carmel McAloon on 0415 308 811 or go to link.
