Renata Rojas, a mission specialist for OceanGate, is set to testify before the US Coast Guard regarding the Titan submersible implosion that killed five people, including CEO Stockton Rush. Testimonies have revealed a concerning company culture focused on profit over safety, with former operations director David Lochridge detailing past incidents involving Rush's reckless behavior in submersibles. Lochridge recounted a 2016 crash with another submersible, where Rush ignored warnings about potential risks, leading to dangerous situations. The Titan's final communications, sent just before the implosion, indicated a lack of awareness among the crew about the impending disaster. Concerns over the Titan's safety had been raised previously, including incidents of partial sinking during missions and the use of outdated materials in its construction. The ongoing hearings aim to shed light on these troubling patterns and the overall safety practices of OceanGate.
