The Titan submersible disappeared in the North Atlantic on June 18 last year, 1 hour and 45 minutes into a dive to explore the wreckage of the Titanic. Five men were on board: Stockton Rush, the submersible’s pilot and OceanGate’s founder and CEO; Hamish Harding, a British aviation executive and seasoned adventurer; Paul-Henri Nargeolet, a retired French navy commander who had led several expeditions to the Titanic; and British Pakistani businessman Shahzada Dawood and his 19-year-old son, Suleman. After an extensive search, rescuers found debris from the Titan on the ocean floor, about 550 yards from the Titanic, and later recovered human remains. The Coast Guard said the vessel suffered a catastrophic loss of pressure and imploded, killing all of its passengers.
