An engineer from the National Transportation Safety Board is set to testify about the implosion of an experimental submersible en route to the Titanic wreckage. The investigation into the implosion of OceanGate’s Titan submersible, which resulted in five deaths, is ongoing. Testimony at the Coast Guard hearing has highlighted concerns about the company’s focus on profit over safety and science. The hearing aims to determine the cause of the implosion and has raised questions about the future of private undersea exploration. OceanGate has suspended operations and is cooperating with the investigations.
