My condolences to his family and friends.
Moon was an absolutely first rate guy. His word was better than a contract. He was a "doer" not a talker. Some people would look at the P51 wreckage he started with and say "that will never fly again". In effect those would be words of inspiration to him. When someone else built a plane that was not completely accurate he would say "well, it is flying!". When I passed through on the way to the Cleveland Air Races in '79 I met him. He became the first mentor for me in warbirds. He was the first person I met that actually went out and salvaged a warbird, rebuilt it and flew it.
