While none of us can absolutley 100% refute the claims that the Chinese had a helicopter that far back it seems that they are trying to rewrite the entire history of the world from the year dot. They currently claim that all the advances made by the Greeks and Romans during various periods in world history were simply ideas taken from the Chinese and they are teaching this in their schools.
If China is such a world-leader in helicopter design, why is it that the majority of their helicopter production has been based on other people's designs (Mi-4,Mi-8, SA365 Dauphin and AS350 Squirrel)? Cannuck is right. It's just propaganda.
