I intentionally did this on purpose. Because when you speak of kites and human flight, you may have to introduce accidental discoveries. Things that are discovered to be true when evidence nor belief was needed.
For example, history doesn't show that kites were originally designed for human flight. The chances that discovering that a kite can lift a man in the air is something that a kite maker who was interested in seeing how big he can make a kite would have probably experienced. The bigger the kite the more likely this becomes a reality.
Eventually you'll have ask yourself. Was the kite originally designed for the intention of human flight. Or was it something that was discovered by accident when someone decided to make a big kite and fly it. You will also have to ask about the history of kites and how it came about. Was it something that was created by sailors? No one knows. Because of that lack of knowledge you'll end up with a bunch of people having theories and beliefs about how the first kite was created and how did it come about. So I picked a specific area about flying that would make it possible to research and actually find how it came about.
For marital artists we have the worst focus. The title of the thread is about Aikido and here we are talking about kites.
