Also, I decided to verify the US Army Air Corps thing and the USAF was formed in September of 1947 - or just a couple of years after WWII ended.
My history is fairly good, but I'm not sure - I suspect Doolittle (and some maybe some dude whose name began with an M - I can't remember his name after this much wine) would have been a proponent and a very influential person. I do know that some lenience in the Air Corps and Air Force helped make automobile racing more popular - and not just in the US. Quite a number of race tracks, even those that still exist, are on old airfields.
