Personally, I think they should be left alone. Those men died on those ships and had no say about their burial. It would be OK to take pictures and such of them but they should be left undisturbed. Like the Germans said when the Bismarck was found. I'll bet the Japanese also say the same since they found the " Musashi " recently. It is their last resting place and not necessarily their choice. They fought and died there and should be left alone for Eternity!
Should sunken warships, which are effectively "the last resting place" of many of those that served on them, be left undisturbed, as you would a human grave on land?
I think they should be left alone. To me, there's no difference in disturbing these military personnel where they lay, than disturbing a grave in a cemetery. Leave them rest, they deserve that much.
