Renata Rojas, a mission specialist and Titanic enthusiast, is set to testify before the U.S. Coast Guard about the 2023 implosion of the Titan submersible, operated by OceanGate. The hearings have raised significant concerns regarding OceanGate's operational practices and safety standards. Former employees, including David Lochridge and Tony Nissen, revealed they had serious reservations about the sub's design and the company's eagerness to launch despite safety warnings. The Titan's final dive on June 18, 2023, ended tragically, killing all five aboard, including CEO Stockton Rush. The Coast Guard's investigation has released new footage and text messages illustrating the sub's catastrophic failure. Public scrutiny continues as more witnesses are scheduled to testify.
