the reactor didnt blow on the thresher....
Deep sea photography, recovered artifacts, and an evaluation of her design and operational history permitted a Court of Inquiry to conclude
Thresher had probably suffered the failure of a weld in a salt water piping system, which relied heavily on silver
brazing instead of welding; earlier tests using ultrasound equipment found potential problems with about 14% of the tested brazed joints, most of which were determined not to pose a risk significant enough to require a repair.
