I thought the one in Huntsville got cannibalized for the Soyez project, didn't know they had the whole rocket.
They still got the SR-71 out front? (been a while since I was up there)
Part of the tour was going through the section where they were assembling the modules for the space station. They had a really cool welder that first hit the joint with a plasma cutter and followed behind with a TIG. They claimed it would do about 50ft of weld before an air bubble might happen. They showed us a sample weld, it was unbelivabley perfect.
There were a couple guys sitting in there, doing nothing.
(you'd think they'd tell them when a tour goes buy to try to look busy)
My brother worked at the Lewis research center in Cleveland, heck of a wind tunnel there. I especially liked the "fruit fly" test.
