In Dulles, Virginia.
At the Udvar-Hazy Center of the National Air and Space Museum, about 40 minutes’ drive outside of Washington DC near Dulles Airport.
This is the SR-71 Blackbird, the coolest plane ever. Maybe after the Stealth Bomber. Oh yeah, and the Space Shuttle Discovery is in the background.
Needless to say, this a very very cool place. It also houses the Enola Gay and Air France’s Concorde.
