Ministry of Defence UFO Reports File: D/Sec(AS)12/2, Part J

This document is a Ministry of Defence file (D/Sec(AS)12/2, Part J) containing a collection of reports regarding Unidentified Flying Objects (UFOs) observed across the United Kingdom between August and December 1990. The file consists of standardized 'Report of an Unidentified Flying Object' forms, telex messages from RAF stations, and correspondence from various police forces. The reports detail a wide variety of sightings, ranging from stationary lights in the sky to objects described as having specific shapes, such as 'half-circles,' 'cigar-shaped,' 'triangular,' or 'diamond-shaped.' Many observers reported these phenomena while outdoors, often in the evening or at night, and frequently noted the presence of multiple lights. The documentation includes details on the meteorological conditions at the time of the sightings, the methods of observation (naked eye, binoculars, or telescope), and the movements of the objects. Several reports mention the involvement of local police forces, who often acted as the initial point of contact for the public. The file also contains internal administrative notes, including disposal recommendations and records of the file's review process. Notably, the file includes a specific inquiry regarding photographs of an alleged UFO near Pitlochrie in August 1990, which the Ministry of Defence reviewed and concluded were likely of a Harrier jet. The reports reflect a consistent administrative process for handling public inquiries about aerial phenomena, with the Ministry of Defence maintaining a record of these events while generally emphasizing that they do not conduct in-depth investigations into the nature of the objects unless they pose a threat to national security or air safety.
