The Udvar-Hazy Center in Chantilly, Virginia is the companion facility to the Museum on the National Mall in Washington, DC. Opened in 2003, its two huge hangars — the Boeing Aviation Hangar and the James S. McDonnell Space Hangar — display thousands of aviation and space artifacts, including a Lockheed SR-71 Blackbird, a Concorde, and the Space Shuttle Discovery. The Center also offers the Airbus IMAX® Theater and the Donald D. Engen Observation Tower, which gives you a 360-degree bird’s-eye view of Washington Dulles International Airport and the surrounding area. Udvar-Hazy Center is also home to the Mary Baker Engen Restoration Hangar where preservation of the National Air and Space Museum’s collections takes place. A glassed-in mezzanine provides a view of restoration projects in progress. There are many things to do while visiting the Udvar-Hazy Center. Daily tours and educational activities for both children and adults are offered.
