actually, i was making a joke. i've never read about a
400mpg ac. i believe one might cruise at 300 if it were in excellemt shape. i know that there are wartime pilots that claim they had ias's of over 350 during pamic dives, but i wonder. are there any dive tests with modern powerplants? there are many rock bands who use/own dc3's becuase they can land almost anywhere and are cheap to operate. i've even read of a guy who lived in his while he flew around the country like an rv'r. but aren't there supposed to be 2 pilots? the idea is pretty cool. and no semis to blow you off the road.
