1950s The Secret Film of Avrocar - The Canadian UFO

“The Avro Canada VZ-9 Avrocar was a vertical take-off and landing aircraft developed as part of a secret U.S. military project carried out in the early years of the Cold War. Two prototypes were built as test vehicles for a more advanced USAF fighter and also for a U.S. Army tactical combat aircraft requirement. In flight testing, the Avrocar proved to have unresolved thrust and stability problems that limited it to a degraded, low-performance flight envelope; subsequently, the project was cancelled in September 1961.”
