We introduced you some of the weirdest aircraft of the 20th century before, but now it's time to talk about Earth's fleets of flying saucers. Check out these vehicles and concepts that show how we've been building UFOs all along.
Only two of them were built for the U.S. Army. It had serious stability problems and the project was cancelled in September 1961.
The famous aircraft builder Chance Vought built the first ever disc-form aircraft, the umbrellaplane, in 1911. It flew several times at Chicago's Cicero Field, according to contemporary sources.
The aircraft with a circular wing on top of the fuselage was designed by an aeronautical engineer named Stephen Paul Nemeth.
Vought-Zimmerman V-173, the "Flying Pancake", designed by Charles H. Zimmerman for the US Navy during WWII
The first flight was on 23 November 1942, and it had almost 200 more (in 131.8 hours) to 31 March 1947, when the experimental test aircraft was retired.
Most of the parts came from a wrecked Messerschmitt Bf 109b and the engine from a Messerschmitt Bf 108. After some unsuccessful takeoff runs in 1944, the AS-6 was broken up to salvage the wood.

The British Rail flying saucer, designed by Charles Osmond Frederick, patented in 1970, granted in 1973
The inventor wanted to use this saucer as a large passenger craft for interplanetary travel. It was to be powered by controlled thermonuclear fusion reaction, using laser beams.
The Russian Flying Saucer, the EKIP or Tarielka, a series of experimental Soviet aircrafts built by Lev Nikolaevich Schukin between 1978 and 1996
The first tests were successful, but after the fall of the Soviet Union the funding of the project was stopped. Schukin and few other scientists could continue the project until 1996, when it was finally ended.
A 300 ton version could carrying 100 tons of passengers and cargo, according to Schukin.
The main section is filled with helium, and the other is filled with air that can be heated or cooled.
The project was cancelled in the 1990s, but it was revived by the company Lokomosky under the name Locomoskyner.
It has an internal combustion engine and works by blowing air over its top.

The M200 Neuera uses eight computer-controlled fans to hover up to 10 ft (3 m ) above the ground. Moller is attempting to build a successful flying car since 1974.
