So anyway I just got back from the Smithsonian National Air and Space Museum, and the Uvar Hasley center or whatever its called and I saw about 30 different world war II era planes. Also some 10 soviet war era planes, and about 20 WWI planes. Id recomend the center instead of the smithsonian, the NAaSM only has the Zero, Spitfire, P-51, Mc. 202, some of a B-26B, a Bf-109 and its awesome engine, all of the different faction's flight suits, a Dauntless, a Wildcat, and some assorted small stuff and engines, not to mention the V-1. The center dwarfs this with its B-29 Enlola Gay, its Me-163 Komet, Arado-234, J1N1, the vast majority of a Heinschel 219, a small flying wing prototype and a piece of a bigger one, experimental helicopter, Loon missile(afterwar V-1 Copy), Ju-52 (airliner variant), early P-51 (after war racing plane), P-80, P-38, P-61, an aichia series seaplane, a kingfisher, a hellcat, a P-40, a Corsair, an Ohka (of course those are rare). They had everything but a russian WWII plane, which im pretty sure only Russia and parts of Europe have.
