Visible crew/equipment: After Reggie touches the metal poles, he goes flying backwards. As he hit's the floor, you can see a thick white rope attached to his left foot. (01:11:10)
Continuity mistake: In the final scene on the bridge, Spock and McCoy are wearing colored arm bands which identify their departments: Spock's is orange (for Science) and McCoy's is green (for Medical). In the very last shot, Spock is wearing the green band and McCoy is wearing the orange one.
