@cstross @Richard_Littler This is why I've always liked the Woodman hypothesis. He says "OK, let's suppose Von Daniken is right about the Nazca lines: they were meant to be viewed from the sky. Does this really necessitate aliens? Or is it possible that the people of ancient Peru simply invented flight?" And then he goes and demonstrates that it is indeed possible by building a hot air balloon using only materials and tech known to have been available to the builders of the Nazca lines.
