Cowden Ward out of Burnet, Tx came up to Warbirds and Legends Airshow in Topeka, KS last year in his P-51, Pecos Bill. I took my dad to the show, an 88 year old WWII and Korea vet. As we were admiring his plane, a member of his group asked me if my father was a vet. I told her yes, and they had me fill out dates of service and branch, then told him he had a free ride coming. They took him up in the P-51 for a fairly long ride. On landing he decided he'd joined the wrong branch of service (infantry). Couldn't stop grinning for a week.
These great folks then told us to head over to a C-47, Skyking, a plane that actually was involved in every airborne drop in the ETO. They then took my 13 year old son, father and me up for fantastic flight, again free. A really great group of folks. I understand they do this at all the airshows they attend.
