In TMP, when viewing Epsilon 9, there look to be a few hundred crew members, even though I don't expect that's everyone on board. How many are on board during the "little training cruise" in TWOK? Crew shots when Admiral Kirk et al enter the ship, and shots of Engineering and Spock's funeral add up to, what, several dozen? How many experienced crew and trainees would be aboard such a mission? Same question, I suppose, for who's left in TSFS as the Enterprise heads back to Spacedock. Admiral Kirk mentions that the vessel seems empty after the trainees have been re-assigned, and we see one scene in the torpedo bay with what looks to be less than twenty crew members. Again, I'm sure that's not everyone, but if most of the trainees have departed and the ship seems empty, how many are left before the Enterprise returns home?
