       | a submarine disappeared much further away than the titanic wreck,
       | much closer to Spain, and the recordings were eventually used to
       | prove it was a collision of submarines or something like that.
       | And rule out that the submarine was attacked by a torpedo.
       | 
       | So I haven't been following this story all that closely, but I
       | would've been somewhat more surprised had there been an implosion
       | or similar it wasn't sitting on a recording somewhere. How quick
       | it is to extract, triangulate, etc are another story.

         | This counts as a maritime accident so the NTSB will likely be

         | 
         | Besides, the vast majority of that money is already spent. The
         | variable cost is actually quite low - largely just overtime and
