This story originates with the mysterious sinking of the nuclear-powered attack submarine USS Thresher (SSN-593) east of Cape Cod on April 10th, 1963 and ends with a deep dive on a piece of submarine safety history off the coast of San Diego, California with a detour to Morro Bay Maritime Museum in-between.

It is a long but fascinating piece of U.S. Navy submarine safety history.

Get a large cup of coffee and settle in…
