Herschel H Green, P-51 fighter Pilot Ace, flew with the 325th fighter group, "Checktail Clan." He flew P-40s, P-47s also. Grounded after 18 aerial victories. He was the leading Ace of the 15th Air Force. Highly recommend this book: "Herky!, The memoirs of a Checkertail Ace." Many great pictures too.
