A key employee who labeled a doomed experimental submersible unsafe prior to its last, fatal voyage testified Tuesday that the tragedy could have been prevented if a federal safety agency had investigated his complaint. David Lochridge, OceanGate’s former operations director, said he felt let down by the Occupational Safety and Health Administration’s decision not to follow through on the complaint. Earlier in the day, Lochridge said he frequently clashed with the company’s co-founder and felt the company was committed only to making money.

The lead engineer for an experimental submersible that imploded en route to the wreck of the Titanic says he felt pressured to get the vessel ready to dive and refused to pilot it for a journey several years earlier. Tony Nissen is the former engineering director for OceanGate, the company that owned the Titan submersible. Nissen was the first witness at a Coast Guard hearing in South Carolina on Monday. The hearing is being held to determine what caused the implosion. The Titan imploded on June 18, 2023, killing all five on board, including a co-founder of OceanGate.

Kate, the princess of Wales, says she has completed chemotherapy and will return to some public duties in the coming months. The 42-year-old wife of Prince William is expected to undertake a light program of engagements until the end of the year. Kate announced in March that she was being treated for an undisclosed type of cancer. Kate attended a ceremonial birthday parade for her father-in-law King Charles III in June, and the following month presented the men’s winner’s trophy at the Wimbledon tennis championships.
