NASA Oblique Wing Research Aircraft

Here's something very unusual! NASA commissioned this unmanned flying test bed to test the aerodynamics of the oblique wing. Though this model, of course was subsonic, data were gathered to ascertain whether a supersonic aircraft of this type would be twice as economical as a more conventional delta wing aircraft; moreover , this model was used to study the low-speed characteristics of an oblique wing aircraft. This model was used as the basis of the manned AD-1 research aircraft.
