A torpedo from John F. Kennedy's PT-109 rests some 1,200 feet (360 meters) underwater in the Solomon Islands. Key details from the torpedo and its nearby launching tube helped identify this wreck site as that of the World War II boat.
The jury-rigged scraper in the foreground was attached to a remotely operated vehicle (ROV) and dubbed STUPID (sediment transport unit piloted in depth) by the search team. It was used in a fruitless attempt to clear away sand and reveal more remains of PT-109.
