No survivors after Titanic sub wreckage found on ocean floor

The five people aboard a missing submersible died in a "catastrophic" event, a Coast Guard official said on Thursday, bringing a grim end to the massive search for the vessel that was lost during a voyage to the Titanic.

"These men were true explorers who shared a distinct spirit of adventure, and a deep passion for exploring and protecting the world's oceans," OceanGate Expeditions said in a statement. "Our hearts are with these five souls and every member of their families during this tragic time."
