My dad worked on the lunar rover, built parts for it. He had no knowledge what the parts went to at the time. We were watching a moon landing, when my dad jumped from his chair and ran up to the tv set and yelled "I made that part right there!" and pointed to a piece on the rover. I shouls add, we lived in Los Alamos, N.M. at the time, and the management never told the employees what they were doing, just gave them instructions or a drawing and told them to make it. Oh ya, there were armed guards at the entrance to town when we first moved there, but were gone when we moved away in the late 60's, and machine gun towers were being torn down.
