Colombia Ancient Aircraft Figurines

In 1997 two German aviation experts conducted an experiment. They reproduced one of the figurines in a scale model to see if it is capable of flight. The only parts they added that were not originally present in the figurine were the landing gear and the engine. All other features remained exactly the same, only were scaled up, not an inch of the proportions added or removed. Once fixed with the landing gear and the engine the scale model was placed on a runway and set in motion by radio. And it flew!
