My dad and I took a trip up to see the new Smithsonian air museum near Dulles Airport last year. He is an aeronautical engineer and ran the test lab at LTV for forty years. His name is on one of the panels located in front of the museum. He was disappointed that they did not have an actual shuttle there yet. His test lab did the testing on the nose cone for the shuttles, and he wanted to see what one looked like after many hours of flight. I guess we will have to go back when they get Discovery settled in.
They didn't have one, because we weren't finished with them yet! I don't know how long they're projecting till the display is ready, though.
