Smithsonian National Air and Space Museum; Washington, D.C.
With approximately 50,000 artifacts from microchips to Saturn V rockets, this museum's two facilities are must sees. The one on the National Mall in Washington, D.C. opened in July 1976. Walking through the halls, visitors can view the original 1903 Wright Flyer, Charles Lindbergh's Spirit of St. Louis, Chuck Yeager's Bell X-1, John Glenn's Friendship 7 spacecraft, the Apollo 11 command module and a lunar rock sample.
The museum's second location is in Chantilly, Va., and showcases relics in an airplane hangar-like setting. Here, you can view a Lockheed SR-71 Blackbird, a Concorde, the Boeing B-29 Superfortress Enola Gay, the "Dash 80" prototype for the 707, the Boeing 307 Stratoliner and space shuttle Enterprise.
