This museum, near Dulles Airport, has the space to allow literally hundreds of aircraft to be displayed. From some of the earliers models to the Blackbird. But the current start of the show is the space shuttle Discovery. When I visited recently, there was a docent with a laptop who seemed very knowledgable and had a loptop handy with photos and technical information. For instance he explained the streaking on the tiles and the different types of thermal shields on the shuttle.
