Memorandum on Sighting of Unconventional Aircraft

Summary

A 1999 memorandum reveals that the CIA investigated an unconventional aircraft sighted in Canada, possibly linked to a U.S. project. It mentions a design with a circular wing 30 feet in diameter and 11 feet thick, capable of climbing at 20,000 feet per minute and reaching an altitude of 402,000 feet. The project, funded with $300,000 by the Air Force, included wind tunnel testing. It is speculated that the design might have originated from a post-war German group. The report suggests the observed objects might already be in service, implying rapid technological progress.

The text also raises suspicions that the Soviets might be working on a similar project, although no concrete evidence has been found. The Air Force planned to interview witnesses to gather more details on the sighting. This document reflects the CIA's interest in unconventional aerial technologies during the Cold War.
