Sorry, but it will be salvaged. Then chopped up and removed, dragged to deeper water, or blown in place. It is a nav haz, so it won't be staying there. Plus it is worth millions upon millions of dollars. It aslo needs clean up, as it has contaminated the water with oil, chemicals, and trash. If you tried to dive it, they'd arrest you for trespassing. It is still owned by the cruise line, and not public property. Maritime law can be a slippery slope. We had sport divers run off all the time out in the Gulf. Technically it is illegal to dive on an active oil platform. It is also illegal to enter, or take things from, the U-boats off NC without permission. Those still belong to the German government.
I am going back to school. Forget this engineering stuff. I want to be a lawyer.
