I never mentioned the Space Shuttle being in orbit at the time, either. I did, however, make the assumption that it was an active Shuttle, not one in a museum, where interested persons could climb all over it with few restrictions.
I am quite aware that the set of people who have access to the Shuttle is much larger than the set of people who fly in the Shuttle.
At that time  the chief engineer was almost always the chief test pilot as well. That had the fortunate result of eliminating poor engineering early in aviation.
