Unusual Aerial Sightings Bendigo VIC 20-24 May 1983

This document is a comprehensive report by Flight Lieutenant B. Biddington of the Royal Australian Air Force (RAAF) regarding a series of unusual aerial sightings reported in Bendigo, Victoria, between May 20 and May 24, 1983. The report details how numerous witnesses observed bright, multi-colored lights in the sky, which were often described as cone-shaped or cylindrical and capable of rapid rotation. The RAAF conducted an investigation, centering on imagery obtained by local witnesses, including Russell Henthorn and Michael Evans. The investigation sought to correlate these sightings with known phenomena, such as meteorological conditions, satellite passes, and astronomical bodies. Meteorological data indicated the presence of low-level temperature inversions in the region, which the RAAF suggested could have caused light refraction, potentially explaining some of the observations. Furthermore, the report notes that some of the photographic evidence was identified as the star Procyon. A radar reflector balloon was also recovered in the area, which was identified as a man-made object. The RAAF concluded that the sightings did not pose a threat to national security and that the majority of such reports are attributable to natural or man-made phenomena. The document also includes procedural instructions for RAAF personnel on how to handle future reports of unusual aerial sightings, emphasizing that 'lights in the sky' are generally not a cause for RAAF investigation unless they involve incursions into Australian airspace by man-made objects or occur near sensitive defence establishments. The report concludes that the RAAF's role is to assess reports for defence implications, and that civilian UFO research organizations are better suited to address reports of an extra-terrestrial nature.
