Watch Log and Unusual Aerial Sighting Reports — RAAF Base Pearce

This document collection comprises a series of watch logs, correspondence, and policy telexes from RAAF Base Pearce in Western Australia, spanning from 1986 to 1994. The logs document routine base activities, security incidents, and numerous reports of 'Unusual Aerial Sightings' (UAS) made by military personnel and civilians. The reports describe various phenomena, including bright lights, triangular formations, and objects exhibiting erratic movement. The correspondence reveals a clear shift in the RAAF's approach to these sightings. Initially, the RAAF actively collected and investigated reports, often involving the Special Air Service (SAS) and other military units. However, by the early 1990s, the RAAF formally adopted a policy of disengagement. The telexes from 1993 and 1994 explicitly state that the RAAF would no longer devote resources to recording or investigating UAS, as there was no compelling reason to do so. Instead, the RAAF began referring all such reports to civilian UFO research organisations, such as the WA UFO Investigation Centre. The documents also include specific incident reports, such as a 1987 sighting at RAAF Learmonth involving SAS personnel, where communication failures were noted during the event. The collection concludes with administrative notes confirming the completeness of the files and the finalisation of the policy change, marking the end of the RAAF's formal involvement in the investigation of unidentified aerial phenomena.
