Well, that's the govt's STORY -- turns out, they had more than they claimed (like, they claim they lsot the part that has the bell on it, but then after the cold war ended, we gave Russia the bell). So many secrets on both sides.<quoted text>
I watched a documentary about that a few years ago. It was very covert and interesting.
They actually used a huge claw to go way down to the bottom of the ocean. The ship was specially built to be very stable and not move because any relative movement between the ship and the claw, which was very long could put too much stress on it and break it.
If I remember correctly, they only recovered part of the sub as part of it broke in half as they were retrieving it.
But yeah, fascinating stuff.
