OceanGate founder and CEO Stockton Rush crashed a submersible into a shipwreck and then threw the vessel’s rudimentary controls at a more experienced employee years before he piloted the doomed Titan voyage last summer.

A former OceanGate worker gave a warning to the CEO of the company before the Titan submersible disaster. It’s been just over a year since the Titan sub suffered a ‘catastrophic implosion’ on its mission to visit the wreck of the Titanic.

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.
