The U.S. Coast Guard has initiated hearings to investigate the fatal implosion of the Titan submersible during its June 2023 dive to the Titanic wreck, which resulted in the deaths of all five passengers, including OceanGate CEO Stockton Rush. Key testimony came from former OceanGate employees, including engineering director Tony Nissen, who described the Titan as an 'unregistered, uncertificated, non-classed machine' and revealed that he had previously refused to pilot it due to safety concerns. David Lochridge, who had labeled the Titan as 'unsafe,' is expected to provide further insights into the vessel's failures. The investigation aims to uncover potential misconduct or negligence and will involve cross-examination of witnesses under oath. As the hearings progress, the Coast Guard and the National Transportation Safety Board will work towards determining the cause and issuing safety recommendations to prevent similar tragedies in the future.
