Project 10073 Record Card and Air Intelligence Information Report — London, England, 25 May 1955

This document comprises a Project 10073 record card and an Air Intelligence Information Report regarding a UFO sighting in London, England, on 25 May 1955. The witness, an employee of the Board of Trade, reported observing a round, amber-red, self-luminous disk while watching an American four-engined bomber. The witness, who was using 8x30 prismatic field glasses, claimed the object hovered at approximately 30,000 feet for about two and a half minutes before performing erratic maneuvers, including a sharp veer to the north and a sudden reversal of course, followed by an incredibly fast departure to the west. The witness provided a detailed questionnaire to the British Flying Saucer Bureau, which was subsequently included in the official military report. The military investigation, conducted by the 3rd Air Force, dismissed the sighting as a product of the witness's imagination. The investigating officer explicitly noted that the witness was a 'fanatic' believer in flying saucers and that this was his third such sighting in nine years. The report includes a sketch map of the locality and the witness's own account of the event, emphasizing the object's deliberate and intelligently controlled movements. Despite the witness's insistence on the object's physical reality and its distinct difference from conventional aircraft, the official conclusion remained that the report was not a genuine aerial phenomenon but rather a reflection of the observer's bias.
