Declassified Australian UFO Report of 1973

Summary

In 1973, the Royal Australian Air Force investigated multiple sightings of unidentified flying objects across Western Australia. The declassified reports indicate that witnesses described a bright object moving rapidly across the sky, with lights flashing and fading. Authorities concluded that the phenomenon was likely the result of the re-entry into the atmosphere of an expended rocket associated with the launch of the Soviet spacecraft COSMOS 555. This rocket, approximately 40 meters long, burned up upon atmospheric re-entry, explaining the intense glow and observed trajectory.

Eyewitness accounts included detailed descriptions of the object's path, stretching from Port Hedland to Kalgoorlie, passing near the Great Australian Bight. The Australian Air Force thanked the witnesses for their reports and assured there was no evidence of extraterrestrial activity. The files also show how investigators ruled out other possibilities, such as known aircraft or satellites, due to the object's speed and behavior.
