Many have long suspected the US Air Force has a special interest in flying saucer technology. It would seem they were not wrong after all.
Declassified documents from the Aeronautical Systems Division, USAF (RG 342 - Records of United States Air Force Commands, Activities, and Organizations) reveal that the military did indeed experiment with UFOs and tried to develop a high-tech flying saucer, but the result was much different than expected.
According to these classified documents the U.S. Air Force had a contract with a now-defunct Canadian.
The National Archives recently published never before seen schematics and details of a military project conducted in the 1950s. The name of this venture was "Project 1794" and its goal was to construct a supersonic flying saucer.
The flying vehicle was meant to reach a top speed of "between Mach 3 and Mach 4, a ceiling of over 100,000 ft. and a maximum range with allowances of about 1,000 nautical miles."
This image is part of a document titled "Project 1794, Final Development Summary Report" (d.1956) . It shows an artistic impression of what the flying saucer should look like when finished. The caption reads "USAF Project 1794"
The VZ-9- AV Avrocar was a Canadian VTOL aircraft developed by Avro Aircraft as part of a secret US military project carried out in the early years of the Cold War. Two prototypes were built as "proof-of-concept" test vehicles for more advanced USAF fighter and US Army tactical combat aircraft. The Avrocar intended to exploit the Coand? effect to provide lift and thrust from a single "turborotor." Thrust from the rotor was diverted out the rim of the disk-shaped aircraft to provide anticipated VTOL-like performance. In the air, it would have resembled a flying saucer. In flight testing, the Avrocar proved to have unresolved thrust and stability problems that limited it to a degraded, low-performance flight envelope.
The main idea was that the UFO should be able to spin through the Earth's stratosphere at an average top
speed of about 2,600 miles per hour.
As impressive as it might sound, developing the craft turned out to be impossible. The US Air Force failed to build the vehicle and Project 1974 was abandoned in 1960. So, whatever UFO-like flying objects people have been sighted in the skies, one thing is certain - it is not the Avro Aircraft.
