I think they should fire up a VIIC sub, send on a month or two patrol, under the conditions that they lived under. Of course I don't think the Bdu would appreciate her report when she got back.
Maybe she would prefer "Hunt for Red October", much cleaner subs and well dressed actors. She should wake up and smell the month old food and read a little history on what they (all WWII submariners) went though.
Maybe she is Bernard's sister ??
