When a Russian nuclear submarine had several explosions in the forward section the crew were entombed 100 metres down on the sea bed.

Their fate was sealed, but experts from across the world worked to ensure they were returned to their loved ones.

Two video links are below 15 minutes each: The second should follow on after the first, but I`ve linked both parts incase. Or the third link is a 50 minute full version if you have the time.

An amazing story.
