Unusual Aerial Sightings - Base Squadron, Pearce

This document is a compilation of correspondence and reports maintained by the Base Squadron, Pearce, R.A.A.F., regarding 'Unusual Aerial Sightings' in Western Australia between 1951 and 1960. The file contains numerous reports from civilians, police departments, and meteorological services. Many of the sightings involve objects described as cigar-shaped, round, or flat, often accompanied by reports of unusual lights, explosions, or roaring noises. The R.A.A.F. frequently coordinated with the Western Australia Police Department to obtain formal reports from witnesses. Several entries involve investigations into potential aircraft activity, with the R.A.A.F. often concluding that no military aircraft were in the vicinity at the time of the reported sightings. Other explanations offered by authorities include meteorological phenomena, such as temperature inversions, or the sighting of planets like Jupiter. The file also documents the R.A.A.F.'s efforts to standardize reporting procedures for these incidents, emphasizing the need for objective data such as bearings, angles of elevation, and duration. The correspondence reflects a consistent administrative process of receiving reports, investigating them through local police or meteorological experts, and forwarding findings to the Department of Air in Melbourne.
