Messerschmitt Me P1109 This aircraft is the only known twin-slant wing aircraft. Designed by German engineers near the end of World War II, the Messerschmitt Me P1109 was designed to reduce aerodynamic drag at high speeds, unlike other twin-slant aircraft.
Aerodyne by Downier It looks like a cylindrical engine and is also known as a "wingless unmanned aircraft". Its engine is encased in a metal cylinder, allowing the vehicle to fly supersonically, and it also has a traditional tail, which was tested in 1972, but later abandoned.
BV 141 of Blohm-Voss Generally speaking, aircraft are all about symmetry, this one is very special, it has the crew cockpit on the right side of the wing, mainly used as a reconnaissance aircraft. Looking very twisted and subverting people's perception of the aircraft, it is said that dozens of this aircraft were also built and not mass produced.
MacDonald's XF-85 "Goblin" This aircraft was designed after World War II and was small enough to carry fighters to protect the parent aircraft when the bomber group was attacked, but the project was later cancelled.
Curtis Goupil's Flying Duck It was designed by a French designer and built in the 1910s, with a unique and very rare shape, designed to imitate a mallard duck, with a round body, powered by a propeller connected to a steam engine in front, and the pilot and landing lift are connected by cables and a frame under the fuselage.
VVA-14 The VVA-14 was designed by Robert Baldini in the Soviet Union, it was designed to take off in the water and also skim the surface to search for enemy submarines, etc. and fly fast. After his death, this was also cancelled.
Saab 21 Saab 21 is the early 1940s, began test flights, mainly to cope with Sweden's involvement in World War II design, the shape looks still very symmetrical, but its seats have ejection function, mainly to avoid pilots parachuting when they touch the propeller, after World War II began service, the latter was also replaced.
Dornier's Do 335 The Do 335 was built by the Nazis during World War II and was a heavy fighter with an ejection seat, but there were delays in engine production and only a few were built after the war ended, but it was still a beautiful model.
Plymouth A-A-2004 This aircraft, which uses asymmetric rotation to generate additional lift, was developed by three inventors and test-flown later, but was eventually abandoned for various reasons, including safety.
Blerio 125 The Blériot 125 was unveiled in 1930 and was said to have a top speed of 137 mph, or 220 km/h, but the passengers would be "packed" in 2 tubes, and only six people could fit inside each, with luggage space included.
