One question about the accuracy of the TNT film "The Hunley" has to do with why the men didn't escape, by letting the sub fill with water, equalizing the pressure, and then lifting the hatch and getting out. My understanding is that in fact the first two sinkings did have 2 or 3 survivors in each lost crew because the men did exactly that. The third crew was probably too deep. Even if a man or two got out, it was too far to get to the surface. This all assumes that the crew has worked out in advance who gets to wait to go first, and second, while the sub fills with water. Not a fun thing to ponder.
