I'm not really clear on why the turbolift would fall in the first place... Is that a gravity plating thing? I guess gravity plating must work without power?
Also Picard knew it was going to fall... are we to infer he'd rather be pancaked than spend another moment with those kids?
I know the writers just think of them as elevators, but why are we generating artificial gravity in a turnolift shaft just so we can overcome it with another generated force?
