In view of the passing of Richard Cole, the last surviving Doolittle Raider, I have attached a link to some interesting photos of the NAA assembly plant and modification center at Fairfax, KS, along with some interesting original color photos, some of which I know you have seen. The main website is a very interesting one, with sectional charts, period, and present-day photos of numerous airfields and airports that are no longer active. I hope this is an appropriate place to post this topic, but Mike, if you feel it best, please move to a more suitable location.
Mike
