Memorandum for Information: Reported Sighting of Unconventional Aircraft

This memorandum, dated October 19, 1955, serves as an intelligence assessment regarding reported sightings of unconventional aircraft. The document links these sightings to 'Project Y,' a research initiative currently underway at Avro Aircraft Ltd. in Canada, which is operating under a contract with the United States Air Force. The memorandum outlines the technical specifications for the Project Y design, which features a circular wing measuring 30 feet in diameter and approximately 1.1 feet in thickness. The projected performance metrics for this design include a speed of Mach 3, a rate of climb of 120,000 feet per minute, a ceiling of 102,000 feet, and a range of 700 nautical miles. The project is currently supported by $800,000 in US Air Force funding for wind tunnel testing. The project is directed by John Frost, who is reported to have derived his initial concepts for the flying machine from a group of Germans active immediately following World War II. The document raises the possibility that the Soviet Union may have acquired similar information from the same German source. The author expresses skepticism regarding the likelihood that the Soviets have such objects in active service, noting that it would be inconsistent with their continued focus on large-scale development and production of conventional aircraft. The Applied Science Division has been monitoring for evidence of Soviet progress on such projects since early 1953. Because the reported sightings occurred in an area where experimental flight is considered unlikely, the document concludes that further investigation is necessary. The Air Force has arranged for technically competent personnel to interview the involved parties to gather more specific details.
