People have been diving down to the Titanic’s wreckage for around 35 years. But so far, no one has found human remains, the company that owns rights to the wreckage says. Now the company, RMS Titanic Inc., is planning for a new expedition that is raising concerns. It wants to send a team to collect the ship’s famous radio equipment and prepare it to be shown in public. But some are questioning the plan, saying the world’s most famous shipwreck could still hold remains of passengers and crew. The disagreement is part of a larger debate over how the Titanic’s victims should be remembered, honored, and respected.
