Pre Incan Aircraft Model
These sculptures could be evidence of many things. Some say birds, other say advanced Inca intelligence, and still others the influence of ancient aliens. In 1997 researchers built scaled up models of these artifacts to test theirflight capabilities. The exact specifications were scaled up and made of materials used for flight of small radio controlled craft. The only additionwas a small engine and propeller. The scaled up versions of the ancient aircraft flew remarkably well performing loops, rolls, turns, as well as takeoff and landing under the radio remote control.
