Although it is the sad end of an era for US space travel, the arrival of the Space Shuttle Discovery at the National Air & Space Museum Udvar-Hazy Center was quite a spectacle. The Shuttle Carrier Aircraft (SCA) 747 carried the Discovery from KSC in the morning arriving at Dulles airport, making a low pass by the museum, flying over Washington DC and then returning to Dulles for another low pass and then landing.
