my heart goes out to them. I was a trained diver for the police, and that is one hell of an envioronment to be stuck in and to try and get someone rescued from.
The Russians have been trying to tow the submarine to shallower water, where divers could cut it free, but are hindered by very heavy anchors reportedly attached to an underwater antenna array in which the Priz is also caught up.
If the Russians were dragging their heels, it could be due to national security issues. They waited more than a day before they asked for any help, which I think is terrible after Kirsk. You would think that one of the prime submariner nations would have invested in rescue strategies and equipment BEFORE that shambles, let alone after.
