And all designs are derived from previous knowledge it doesn't makes any of the bad if fact that good. The proof is in the flying. Computers, wind tunnels and additional knowledge resources have given us a better methods to guess what will happen in flight. The only real pioneers were Orville and Wilber types who did not have much of a knowledge base to adapt their ideas to make something different.
