Hey SHIPWRECK, you weren't being chicken little on this issue and don't hesitate to ask questions here about a submarine because I am SURE that there is someone who will answer your questions

And I did the same thing when the K-77 (Juliette 484) sank in Providence, Rhode Island sank.... That to me was an eye opener to ALL of the boats still in the water, part of me to this day wonders IF I was able to help save another boat.... and yes I do believe that I helped inadvertantly save one or more of our boats so that future generations can see them..
Torsk after that was able to acquire and get running a complete P-100 and all associated hoses to go with that to de-water the boat from topside IF needed (GOD forbid) and I know that others have re-looked at their DC plans.
And sadly enough I had yet to cover anything to do with fire and flooding during the school of the boat because DEEP DOWN, I HATE fires onboard a submarine.. I can fight fires all day long in a barn or a building or a house but NOT being able to leave your home that is on fire to this day scares the living heck out of me and watching the compartments around you go from being crystal clear to the point of barely able to see your hand infront of your face is disturbing as hell to me.
Flooding, I have lived through it and honestly IF a boat that I was on had flooded and I was in the rack I would have never KNOWN if the boat IMPLODED because they don't take too much at deep depths. The last time we weren't too deep (150' maybe) and the hull valve blew off on the evaporator due to the shipyard screw ups and being on watch in the Torpedo Room during a drill it wasn't a big thing because they at the time were running a drill in the compartment AFT of it and once the valve blew off they shifted the training to the real thing and went at it.. Obviously we made it to the surface and it took a while and a failed EMBT blow (busted line) but obviously it surfaced because the crew of that boat (along with me) are still here..
Many people have forgotten that these museum submarines are true warships and they can and will kill you if you let them... A lot of people don't understand what they actually did other then to make them look pretty and tell their stories and I HOPE that they NEVER find out what happens in case of an emergency onboard their boat. ANd no Paul I wasn't busting your chops (others are involved and not just you)
I cannot stress it enough that Damage Control starts with the basics.... LEARN your boat and then learn how to handle ANY situation that comes across your plate in regards to Damage Control within reason.
