OceanGate's Titan sub briefly became tangled up in the Titanic during a 2022 dive, according to a mission specialist who was on the dive.

The passenger testified that the mission was scrapped because the sub couldn't navigate, and was swimming in circles.

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.
