Department of Air File Series 580/1/1: Sighting of Unusual Aerial Phenomena

This archive contains a collection of reports, correspondence, and minute papers from the Department of Air (Australia) regarding sightings of Unidentified Aerial Phenomena (UAP) between 1958 and 1960. The documents include formal sighting reports from various observers, including civilians and military personnel, as well as internal assessments by the Royal Australian Air Force (RAAF). Many reports describe cigar-shaped or spherical objects, often observed hovering or moving at varying speeds. Notable cases include the sightings by Reverend Lionel Browning and his wife in Cressy, Tasmania, and reports from Mrs. D.A. Webster and her daughter. The RAAF conducted investigations into these incidents, often coordinating with the Department of Civil Aviation and meteorological stations. Official conclusions frequently attributed these sightings to natural phenomena, such as Venus, meteorological balloons, or atmospheric conditions, though some investigators, such as Wing Commander G.L. Waller, cautioned against dismissing all reports as optical illusions. The archive also includes correspondence regarding UAP sightings in New Guinea, specifically those reported by Reverend William B. Gill, which were evaluated by the Aerospace Technical Intelligence Center in the United States. The documents reflect a period of heightened public interest in UAPs, with the RAAF attempting to manage reports while maintaining security and scientific rigor.
