Until we moved 10 miles farther south, we lived 5 miles from this location (Udvar-Hazy) near Dulles Airport. Just for an FYI, like all Smithsonian museums, admittance is free, but parking costs $15 per vehicle. Besides the actual museum which is full of all kinds of airplanes including the Enola Gay, there is a mock up of the death star used in filming for Star Wars. There is also a tower you can watch planes take off and land. There are uniforms, weapons, planes, etc, The original space shuttle that was there was moved several years back and replaced with the current one. I have pictures taken from my back yard of the original one leaving Dulles on the back of the 747. I can never remember which shuttle is where.
