. . . The only qualifier is just much of a pain in the tuchus is was to move that shuttlecraft between soundstages and how much maneuvering had to be done around the standing sets, versus setting up sections of corridor next door as well as painting the floor, setting up a wall, etc, for one scene.
I suspect keeping all the action on Stage 8 won that argument.
The shuttle mockup was a big heavy sumbitch. That's not to say they couldn't have schlepped it between adjacent soundstages, but I'm sure it would have been moved only as absolutely necessary.
And the standing Enterprise
sets were on Desilu's Stage 9, not 8.
