A mission to explore the remains of the Titanic went horribly awry on June 18, riveting the world as search crews raced against time to find a submersible that vanished during an attempted dive to the ocean floor, where paying passengers and Stockton Rush III, founder of the submersible company OceanGate, could view the Titanic wreckage.
On Thursday the U.S. Coast Guard announced pieces of the submersible were found scattered across a debris field a third of a mile from the Titanic. OceanGate issued a statement saying, “We grieve the loss of life” of those aboard.
Also aboard the vessel were French explorer Paul-Henry Nargeolet, British explorer and jet dealer Hamish Harding and Shahzada Dawood of a prominent Pakistani family and his son Suleman.
Records show the tragedy was preceded by a long path toward developing a craft that would reach the ocean depths where the Titanic rests. They also show a history of safety concerns.
