A former OceanGate scientific director said the Titan submersible suffered a malfunction six days before imploding in June 2023, killing all five people on board.

Rush “crashed into the rear bulkhead, the rest of the passengers tumbled about, I ended up standing on the rear bulkhead,” ex-OceanGate scientific director said.

Two days of reporting and testifying by experts during a U.S. Coast Guard inquiry challenge the idea that the submersible’s passengers knew they were facing death.
