We spent the day at the new Air & Space (Udvar-Hazy) museum, which is a shuttle ride away from DC, next to Dulles airport. Tooks lots of shots of all the planes. The building is a huge hanger the size of more than 3 football fields. We saw and walked around the Enola Gay, Concorde, Space Shuttle, and SR-71 Blackbird, among dozens of others. You can walk under, over, and around the planes - we spent the day there and had a great time.
