Corrected entry: In one scene, Captain Ramsey threatens to shoot Weaps if he doesn't open the safe that contains the tactical firing trigger. Then he says it does him no good to kill Weaps, as he's the only one who knows the combination to the safe. It is unlikely that only one person knows the combination: what if that person had died in the galley fire or drowned in the bilge bay? The crew is left with a safe that can't be opened.

Correction: Saying something is unlikely does not constitute a mistake, besides your mistake is more opinion than fact. Whether or not someone in the crew should know the combination or not doesn't seem too important. At the time Ramsey was intent on firing the missile and this might have been the quickest and only route that was available to him. Besides, it was the firing trigger, not the oxygen supplies. I think if something happened to him they would at least be able to go on.
