The U.S. Navy said Sunday that it won't be using a large piece of salvage equipment that it had deployed to the effort to retrieve the Titan submersible. The Flyaway Deep Ocean Salvage System had the capability of lifting an intact Titan back to the surface. The U.S. Coast Guard announced on Thursday that debris from the submersible had been found roughly 1,600 feet (488 meters) from the Titanic in North Atlantic waters.
