I don't know what it is about submarines, but they frighten me. How brave are the sailors who live their lives under the sea, always in danger of never seeing the sun again. Just one mistake or one ill-timed move and the sub is lost to all.
This book does a full review of all submarine disasters, starting with the American Civil War. It includes the disaster of the Thresher, which was "crushed by some giant, unseen hand", after a basic welding failure doomed the crew of 129 men to a watery grave in 1963. The next American submarine catastrophe occurred in 1968, when the Scorpion failed to return to base. No one knows for certain if it was torn apart by a hot torpedo or if it was a silent casualty of the Cold War.
And speaking of the Cold War, the book ends with an entire chapter devoted to the Kursk, that Barents Sea sinking in 2000 that kept an entire planet hoping for a miracle that never came...thanks to Russian Navy ineptitude.
There are dozens of photographs, including many showing the current resting state of these lost subs on the ocean floor. After reading this, I wouldn't even be able to do the old Disneyland ride.
