Wednesday, April 10, 1963: USS Thresher

Some 220 miles east of Cape Cod, Massachusetts, the nuclear submarine USS Thresher sinks, killing all 129 aboard. The accident occurred after the submarine lost power and dropped to the ocean floor, breaking apart from the deep-sea pressure.

Photo from the U.S. Navy. Caption reads, "Overhead view of Thresher's upper rudder, photographed from a deep-sea vehicle ... The view shows draft markings on the rudder side and a navigation light at its top. The original photograph bears the date October 1964."
