Perth Western Australia Formation 1958

On July 30, 1958, RAAF Pearce air base radar and Perth Airport ATC simultaneously tracked a formation of unidentified objects performing maneuvers over Western Australia. The formation was also observed visually by RAAF Pearce personnel and by the crews of several merchant vessels in the approaches to Fremantle harbor. The formation performed coordinated maneuvers for 12 minutes before departing at high speed to the southwest over the Indian Ocean. The RAAF's investigation produced a detailed classified report that was forwarded through Australian and US Five Eyes intelligence channels. The case was cross-referenced with similar formation sightings over the Pacific during the same period. Australia's Department of Air maintained a classified UAP files program parallel to the US Blue Book, and the Perth case became one of the most significant entries in the Australian record given the simultaneous multi-sensor, multi-location confirmation.
