NASA’s AD-1 oblique wing aircraft just might be the weirdest plane we’ve ever seen. Simply put, “at high speeds, both subsonic and supersonic, the wing would be pivoted at up to 60 degrees to the aircraft’s fuselage for better high-speed performance.” Click here for more pictures. Continue reading to see it in-action.

Their objective? Better fuel economy: Wind tunnels at NASA Ames showed that an oblique wing design will use half the fuel at supersonic speeds, thanks to superior aerodynamic qualities.
