When I went on the KSC tour several years ago, the Apollo 11 display begins outside the doors with a TV screen telling about the flight going to the moon, the doorso open and you go inside to see the diorama with a mannequin in a space suit standing on the moon and such.
As you’re waiting for those doors to open you hear CAPCOM calling Michael Collins in the Command Module, waiting for him to come out from the other side of the moon.... The CM on Apollo 11 was Columbia. They keep calling for “Columbia” but do not get any answer.
All I could think of was 2003 CAPCOM calling to STS Columbia and getting no reply. It was sad.
Also, at the Air and Space Museum, before they swapped Enterprise for Discovery. There was a missing section of the leading edge of wing of Enterprise. I knew immediately why it was taken out.
I couldn’t imagine the reaction I would have to a display of an actual piece of the destroyed Shuttles.
The wing sections taken out of Enterprise (as well as the landing-gear doors) were Fiberglas and were used to design, build and test the jigs required to hold the Reinforced Carbon-Carbon panels that were removed from the other surviving shuttles for the foam impact testing, without risking damage or loss of those RCC sections prior to the actual tests.
