Trapped in a "metal coffin" on the ocean floor

In 1988, after colliding with a fishing trawler at the surface, the Peruvian submarine Pacocha sank to the bottom of the Pacific ocean. With 22 men trapped inside, with no water, a fire on board and depleting oxygen, First Lieutenant Roger Cotrina Alvarado was determined to save his crew. An escape plan was hatched, but getting out of the submarine was only the first step - they still had to find a way to make the 42-metre ascent to the surface.
