Amazing Plane Without Wings: Incredible Feat of The C.450 Coléoptère

 Throughout the 1950s, aircraft designers around the globe started developing a distinctive aircraft layout, named a tail-sitter. Dissimilar to the typical aeroplanes, tail sitting planes rested on their tails and utilized engine power only to raise off the ground before changing to vertical flight and coming back to land vertically once again on their tail. Despite the configuration, being technically difficult to develop, it would enable aircraft to function without runways, conventionally challenging how and where air forces could use their aircraft.

In the early 1950s, French aerospace firm SNECMA (Société Nationale d’études et de construction de moteurs d’aviation) started developing wingless test rigs to establish the logic of the tail sitting idea. At the time, American companies were also creating tail sitting prototypes of their own, but SNECMA would take it a step further by designing a tail sitting aircraft featuring a highly unfamiliar cylindrical-shaped annular wing.
