Why the USS Thresher Can Never Be Recovered

Two hundred miles off the coast of Massachusetts, in over 8,500 feet of water, lies the wreck of the USS Thresher — the most advanced submarine in the world when it was lost with all 129 men aboard on April 10, 1963. The Navy found the wreck within a year. They photographed it, studied it, and identified the likely cause. And then they left it there. Six decades later, it's still down there. In this video, we break down what really happened during Thresher's fatal test dive, why a single pipe joint may have doomed the entire submarine, and why — even with today's technology — nobody has ever been able to bring the wreck home.
