The "string" story is quite true, it was a popular way to show crewmen just how much the pressure affected the boat. From what I understand the string would "slack" 1"- 2" depending on the depth, the pressure hull was actually compressed that much. The sound of the "creeking" during a dive is actually the pressure hull becomming smaller around, once at "depth" the creeking stops as the hull settles in.
