Are you implying that we, the most humble members of Subron 4, would do such bads things? I'll have you know that we routinely sit around a campfire and sing kumbaya led by Kevin. This is followed by anti-global warming rallies and other such liberal things.
When surfaced, the bridge access hatch can be optionally open or shut, however, when submerged it is required to be shut. (Really a no s***t precaution from a procedure in use in the sub fleet today.)
