Real Planes that look like UFOs
Vought V-173 “Flying Pancake”
In development from 1939 / Operational 1942 – 1947
The Vought V-173 or ‘The Flying Pancake’ was an experimental WWII test aircraft built by the USA as part of the Navy fighter aircraft program. It had a daring, almost circular, “all-wing” design. The project was initiated in 1939 and flight tested by Chief Test Pilot Boone Guyton on the 23 November 1942. Evaluation of the V-173 carried on throughout 1942 and 1943. A total of 190 flights were undertaken prompting numerous UFO reports from worried Connecticut residents. The final test flight took place in 1947. Overall, the project contributed greatly to the understanding of aerodynamics and the possibility of near vertical take offs.
McDonnell XF-85 Goblin
In development from 1942 / First Flight: 1948 / Cancelled: 1949
From the start of America’s involvement in World War II there was concern that US bombers would need long range fighter support. The problem was tackled in two ways. Firstly, the USA developed the Flying Fortress which was meant to be able to defend its formation on its own. Secondly, the USAF wanted to develop a fighter that could be carried by the bombers in their bomb bays. The program to develop a small (parasite) fighter started in 1942. The program was accelerated after the Flying Fortresses suffered catastrophic damage during the infamous Schweinfurt raids of late 1943 but slowed down again with the development of the P51 Mustang long-range fighter. As time went on the specification for the new aeroplane was changed from propeller to jet engine. Project authorisation was slow and the war in Europe was over before prototype development began in earnest. The aircraft showed promise but instability issues, particularly with regard to reconnecting with the mother bomber proved overwhelming. After a series of accidents the project was cancelled during 1949.
Horten Ho-229 Flying Wing
In development from 1943 / Testing: 1945 / Project Transferred to USA: 1945
During 1943 during the height of World War II, Herman Göring, the Head of the German Luftwaffe demanded that Deutsche industry should design and build a fighter bomber capable of carrying 1,000 kilograms of explosives to targets 1000km from their bases at a speed of 1000 kilometres per hour. The Ho 229, designed by by Reimar and Walter Horten was the only plane that came close to the specifications set by the German military. Without unnecessary external control surfaces, powered by two Jumo 004C engines, and with a flying wing configuration it was effectively the first stealth aircraft to be invented. The plane never made it into full combat before the Allies forced Germany to surrender after the fall of Berlin. The designs and components of the HO 229 were smuggled back to America as part of Operation Paperclip. Tests later revealed that while it had a significantly reduced radar signal but would still have been visible to medium range detection systems.
Avro Canada VZ-9 Avrocar
In development from 1951 / Testing: 1959 – 1961 / Project Cancelled: 1961
The Avro Canada VZ-9 Avrocar was a top secret and experimental “proof-of-concept” VTOL vehicle designed and built in Canada and intended for use by the US Military. Powered by a single “turborotor” the aircraft was strikingly similar to the Flying Saucers that were being featured both in serious news reports and children’s comics. Although fascinating to look at and intellectually captivating, the UFO plane never performed sufficiently well to warrant further development. The project was cancelled in in September 1961. It has been suggested that the project was actually never more than a disinformation programme designed to confuse overseas observers and US citizens. Some UFO researchers have even claimed it was part of the Blue Book cover up to be used as an explanation for the large number of ‘unexplained’ UFO sightings that were occurring during the 1950’s
Convair XFY-1 Pogo VTOL
In development from 1951 / Testing: 1954 / Project Cancelled: 1955
The Convair XFY Pogo tail-sitter was an attempt to create a VTOL fighter that could fly from any small warship. These concept aircraft was designed to prove that forward, contra-rotating, propellers would act like the blade of a helicopter and provide sufficient lift to raise the fighter into the air. Although the aircraft did fly its stability was never considered fully acceptable and landing the craft was near impossible. However, the main problem was the plane’s inability to slow down once it had reached combat speeds. To make matters worse, the plane was no match for other fighters being developed at the time and the project was cancelled during May 1955.
