David Lochridge, a submersible pilot and engineer who had served in Great Britain’s Royal Navy and worked all over the world, had expressed reservations about the design and build of OceanGate’s submersible, but his concerns were reportedly dismissed. He found numerous problems with the vessel, including the carbon-fiber hull having “very visible signs of delamination and porosity,” the glue for ballast bags coming off, sealing faces with errant plunge holes, and O-ring grooves whose design was not standard, among many others, The New Yorker reported. When Lochridge brought up his concerns at a company meeting, he was fired.
