lol what are you talking about!!!? If there was an emergancy captains wouldnt run down the ladder across the sub and order a crash dive! They would scream at the top of their lungs through the hatch opening and "ALLAAARRRM" would be passed on throughout the boat. Then the watch would proceed to do the firemans drop down the ladder and all would be safe... unless your those unlucky few boats who dove without their watch crew...
