Results: A new Titanic expedition is planned. The US is fighting it.

The U.S. government is trying to stop a planned expedition to recover items of historical interest from the sunken Titanic, citing a federal law and an international agreement that treat the shipwreck as a hallowed gravesite. The expedition is being organized by RMS Titanic Inc., the Georgia-based firm that owns the salvage rights to the world's most famous shipwreck. The company exhibits artifacts that have been recovered from the wreck site at the bottom of the North Atlantic, from silverware to a piece of the Titanic's hull. Have you ever seen any pieces of the Titanic in person?

The battle in the U.S. District Court in Norfolk, Virginia, which oversees Titanic salvage matters, hinges instead on federal law and a pact with Great Britain to treat the sunken Titanic as a memorial to the more than 1,500 people who died. The U.S. argues that entering the Titanic's severed hull — or physically altering or disturbing the wreck — is regulated by federal law and its agreement with Britain. Among the government's concerns is the possible disturbance of artifacts and any human remains that may still exist. Do you think the Titanic should be left alone and treated as a memorial?
