Noise
Anyone here seen 'Down Periscope'? It's a comedy, so no way should it be taken seriously, but there is an aspect to it (and a few other submarine movies) that is in direct contrast to 'Crimson Tide', and that's noise.
In DP, there is a scene where they are trying to stay silent, and one of the crew members farts, the sound being picked up by the other submarine.
So then we watch 'CT', and only the external sounds of the winch are heard, not the internal sounds of the Captain yelling at everyone over the speaker systems.
Does anyone know what the truth of the matter is regarding submarines trying to stay silent?
