Ancient Airplanes – Is history circular in nature?

“According to mainstream archeology, the pre-columbian Quimbaya culture were believed to live in South America from 300 to 1550 CE and are best known for their precise gold and metalwork. The majority of gold pieces discovered are made with a tumbaga alloy with 30% copper, very similar to those accounts mentioned by Plato in his dialogues about the lost city of Atlantis. Among the intricate gold works are several types of insects and two devices that stand out to be aerodynamic in nature and shaped like no other insect known to exist. The ancient pieces look very much like the designs of modern airplanes and incorporate a number of features essentially proving the Quimbaya knew and understood the principals of flight. Scale replicas of the golden flyer were built five times larger and tested precisely. Results from testing in 1994 proved these ancient mysterious airplane shaped devices were capable of flight, and actually flew very well without any sort of modifications using modern techniques.” – http://www.mysterypile.com/quimbaya.php
