Looking back on it now, the actual crash does look pretty dated. But it is still well done, given when it was made, etc.
One thing about the evacuation that has always puzzled me: why was Sickbay evacuated?
Sickbay was on deck twelve of the Saucer Section, close to the centre of the deck to afford it as much protection as possible. No medical facility was ever established as being in the Drive Section, though it would make sense when the ship was separated, so as to treat casualties during a combat situation--but why would Beverly be there instead of the main facility?
