View of one side of the hanger at the Smithsonian National Air and Space Museum Steven F. Udvar-Hazy Center. This gives you an idea of how much of a visual overload the center can be. It's amazing, and confusing, and not to be missed.
WWII Planes at the Steven F. Udvar-Hazy Center as part of the National Air and Space Museum. I know the one with the propellers facing you is a F4U Corsair (thanks to watching too much Black Sheep Squadron with my father as a kid). The other might be a P40 Warhawk as flown by Chennault's Flying Tigers in China.
Btw, the Steven F. Udvar-Hazy Center is a giant hanger near Dulles airport that houses many of the planes preserved by the Smithsonian National Air and Space Museum. It's worth a trip out.
