On August 29th, 1973, a routine dive to the telecommunication cable that snakes along the Atlantic sea bed went badly wrong. Pisces III, with Roger Chapman and Roger Mallinson onboard, had tried to surface when a catastrophic fault suddenly sent the mini-submarine tumbling to the ocean bed. Badly damaged, buried nose first in a bed of sand, the submarine and the two men were now trapped a half-mile under the ocean’s surface. Rescue was three days away, with just two days’ worth of oxygen.

Today’s guest is Stephen McGinty, author of The Dive: The Untold Story of the World's Deepest Submarine Rescue. In our discussion, he reconstructs the minute-by-minute race against time that took place to first locate Pisces III and then execute the deepest rescue in maritime history. This event show how Britain, America, and Canada pooled their resources into a “Brotherhood of the Sea” dedicated to stopping the ocean depths from claiming two of their own.

Yet, the heart of The Dive is the relationship between Roger Chapman, the ebullient former naval officer, and Roger Mallinson, the studious engineer, sealed in a sunken sarcophagus. For three days they would battle against despair, fading hope, and carbon dioxide poisoning, taking the reader on an emotional ride from the depths of defeat to a glimpse of the sun-dappled surface.
