Here's a scenario for you. It's, say, 2050. The debris field has been picked all but clean, so much so that there are practially no returns to be had from any dives any more; maybe one of the loose boilers has even been raised. The bow section has begun to collapse in on itself-perhaps the damaged tear area has fallen away, internal decks are collapsing in, perhaps some of the shell plating has begun faling in/out as well. The ship is becoming a pile of rubble, and is rapidly changing from the form we know it in now. Would it then be right or wrong to start picking things up from the ship itself? The centenary of the disaster would be long past, the 'ownership' of the wreck could well have changed a couple of times, who knows what public opinion of the ship will be in another fifty years? So does any of that make it right to say, 'rescue' one of the ship's anchors before they get buried under so much steel? Or to start plucking personal items out of the rubble, should they become exposed? When do you think it would become all right, if ever, to start bringing up pieces of the bow section?
