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.

OceanGate’s former operations director David Lochridge, who blew the whistle on safety concerns he had with operations at the company, outlined gaps and holes in the carbon fibre hull of the Titan, which he says was addressed by spraying truck bed liner onto the hull.
