After the USS Scorpion sank with 99 aboard on May 22, 1968, the Navy convened a formal Court of Inquiry to investigate the loss. The court produced three possible scenarios for the sinking, but concluded the most likely cause was that a runaway Mark 37 torpedo accidentally became armed and struck the submarine. In 1970, a different Navy panel disavowed the Court of Inquiry findings, but because of underwater recordings of the event, some Navy officials still believe the court's findings are accurate.
