I think I have visisted almost all the Norwegian wreck sites during my dedicated Norwegian trip on 2004.
Terje is right, they are going soon to be an environmental problem since many are in close waters and still with fuel inside and are polluting the environment already, but they can do more damages soon, especially Blucher in Oslo Fjord I suppose, .. not to talk about that U-Boot in Bergen.
Same problems are coming out also from recently sunken ships and wrecks, especially is loaded with nuclear weapons, like the Russian submarines,..this is going to be soon a very crucial problem for our living environment,..on top of the very many others we already have...
Our old wrecks at least did not have the nuclear problem as they were just steel and cooper, engines and so on, ... but mainly good quality steel.
That is why werever possible they scrapped the sunken ships, for economic reasons, that was the main reason they scrapped the Tirpitz, somebody made a real '' bargain '' of her.
But Tirpitz was not totally submerged, half of her hull was out of the water and there were more than 900 dead German young sailors on her, buried into the steel of their own ship.
When I was in front of her sinking place I was invited to take a swim on her wreck as a scuba diver, I decided NOT to do it, because I was feeling I had to respect that place, like a cemetery, as it really is.
So despite I am a good swimmer and that been an easy task been the water very low, I did not do it.
The destiny of the bodies buried in there is still a very sensitive argument, .. I preffer not to go into the details of it, .... nobody will judge anybody about it on this world, ... GOD will do it one day.
.. it is NOT a matter on nationality, .... it is a matter of been an human been, ... despite the religion, ... the country, ... the flags, ... and in fact Terje is thinking exactly like everybody will do logically
.. lucky me I had the opportunity to listen personally to the words of Harry Pettersen ( Norway undergroud agent, .. now dead ) ... of some Tirpitz survivors on 2005 still alive, ... of John Lorimer ( X-6 crew member ) ... at the Tirpitz Museum opening,... in KaaFjord.... on 2005.
Their words were really inspiring for every young man listening, .. very wise, .. as war is bad and we must learn from previous mistakes not to do it anymore, .. never again.
