As having a relative who died on the Bismarck, I can say that the idea of raising it is completely morbid, and the ultimate desecration of their grave. You have to remember that this is their final resting place. Just like you would never think of raising the USS Arizona, there are just some things you don't do. I could propose the question to you, if you were someone famous, sixty years after your death, would want someone to come dig up your grave and help themselves to some of the belongings you were buried with? Also, even if there are no human remains, just the fact that men died there should be reason enough not to disturb it, and now you want to turn it into a tourist attraction? And what puzzle would you be putting back together? We know almost everything there is to know about the Rhine Exercise, we know it wasn't sunk by the British, so once I again I ask you what puzzle would you be solving? Thank God it is a war grave and can't be disturbed in anyway, so, no disrespect, people with your kind of mentality, can't desecrate this site the way the Titanic has been desecrated. I don't think that recovering people's belongings will help us to understand how the ship sunk, or give any relavence to the Bismarck story. I don't think anyone can understand this unless you have lost a relative in an event such as this one. If anything you should preserve the wreck and create an underwater museum, so future generations could learn from this time in history. Bismarck on the bottom of the ocean reminds us all of a time when the world went mad. That is why it should not be raised or robbed.
