National Air and Space Museum Annex0
The Steven F. Udvar-Hazy Center near Washington Dulles International Airport is the companion facility to the Museum on the National Mall. The building opened in December, 2003, and provides enough space for the Smithsonian to display the thousands of aviation and space artifacts that cannot be exhibited on the National Mall. The two sites together showcase the largest collection of aviation and space artifacts in the world.
This collection includes the Space Shuttle Discovery along with several other awesome pieces of flight history including the Lockheed SR-71 Blackbird and some awesome pieces of Star Wars memorabilia.
Thanks to BobG for these pics – hope to make it up to see Discovery soon.
