In a story published Sept. 16, 2024, The Associated Press reported testimony from former OceanGate director of engineering Tony Nissen about the Coast Guard investigation into the implosion of the Titan submersible. The story should have included that Nissen worked on a prototype hull that predated Titan’s expedition to the Titanic wreckage site. In testimony on Sept. 16 about a 2018 lightning strike, he referred only to that prototype. The prototype’s carbon fiber hull that was hit by the lightning strike was never used on Titanic expeditions, and it was later replaced with a new carbon fiber hull. OceanGate has not answered questions from AP about whether components on the testing version of the sub were ultimately used in the final version that imploded, only that the hull was replaced after the lightning strike.
