Project 10073 Record Card — Sighting Report, England, 29 September 1952

This document consists of a Project 10073 record card and an associated military cable detailing a UAP sighting that occurred on September 29, 1952, in England. At 1555 Zulu time, two objects described as circular plates, approximately five inches in diameter, were observed by an unidentified witness. The objects were initially stationary at an altitude estimated between 25,000 and 30,000 feet before moving off at high speed in a southeasterly direction. The report notes that the objects appeared flat, lacked any visible exhaust, and were traveling at speeds exceeding Mach 1. The observation lasted for approximately three minutes under conditions of very clear visibility with 2/10 cumulus cloud cover. The report explicitly states that there was no aerial activity at the time of the sighting, although it notes that a British fighter aircraft towing a target had been seen in the vicinity of Sheerness approximately ten minutes prior to the event. The sighting was reported to the Rochester Police, who subsequently forwarded the information to RAF Intelligence at Manston. The document was received at the Air Technical Intelligence Center (ATIC) on October 6, 1952.
