It is the Smithsonian National Air and Space Museum Steven F. Udvar-Hazy Center. Located in Chintilly Virginia. The Museum was built on Dulles International Airports property at the south end of the runway and is five years young. The Museum has it's own exit off of RT 28. I have mention this Museum a few in this Forum, topics like, a possible camp ground here on the property, the fly in that happen not to long ago and the shooting of the move " TransFormers II. There is a new addition coming to the Museum, The Restoration Hanger, this is where the public can see and watch how the aircraft are restored. Ground breaking starts in the middle of October. I have collected over 15 CD's full of aircraft and spacecraft being assembled in the new Museum and there delieveries and I was allowed to get in side of some of the aircraft and get pictures of the in sides and the cockpits plus different phases of the construction. This Museum is also know as " AMERICA'S HANGER ". There is a book that is available called " Building America's Hanger, it is about the design and construction of the Steven F. Udvar-Hazy Center written by Lin Ezell. If anyone has any question or want to see pic just let me know, I well be more then glad to share.
