Its design reminds me of the B-Wing but the gyroptère—or monocopter—is even weirder than the beloved starfighter from Star Wars. It had a single blade—the long wing you can see in white—which rotated to lift it to the skies. Try to picture that, because I really couldn't until I saw this video: Unlike this model, however, the gyroptère never got to fly. Theoretically it could but in 1913, when it was invented by by Alphonse Papin and Didier Rouilly, the technical means to get enough rotational speed to fly weren't available yet: Source: http://sploid.gizmodo.com/the-weirdest-aircraft-ive-ever-seen-1622650802
