I agree with you. I've been to the second gallery of the National Air and Space Museum twice. They call it the Udvar-Hazy Center. The first time I went there, they had the space shuttle Enterprise on display. It had never been in space, it was just used to test the shuttle's capability as a glider. So when the Enterprise was on display, it looked too polished and pristine. When the shuttle program ended, the museum replaced the Enterprise with the Discovery. I liked seeing the Discovery much more because it had a lot of gray marks on it. Because of those marks, you could tell the Discovery had been in space many times.
