We will have to agree to differ. Speaking for myself, I still hold the view that they didn't need to disturb the wreck in pursuit of nick nacks to create a memorial. Are you honestly saying that it will somehow be a better quality memorial because there's a piece of Hood stuck on it?
And to extend the debate, we're now good friends (of sorts) with our European neighbours. Do you propose that the bell of the Bismarck be retrieved to remember the crew who fought for their country? Or the bell from the French navy battleship Bretagne, sunk in port by Hood, with the loss of a thousand French sailors?
