The exhibit is part of an initiative by OceanGate Expeditions and its founder, Stockton Rush. Guests take on the label of crew member or “mission specialist,” and enter the actual vessel that has been to the Titanic wreck. Inside, “crew members” can view 4k footage of the Titanic’s current state and learn about ocean exploration.
