On June 18th a submersible called Titan, operated by the private company OceanGate, was deployed ~400 nautical miles off Newfoundland, Canada, in the North Atlantic Ocean. The submersible, bound for the Titanic shipwreck some 12,500 feet deep, was carrying four tourists and a pilot. By now, just about everybody knows Titan never reached its intended destination; it imploded a few hundred feet from the sunken ship. The accidents probable cause was a catastrophic hull failure under immense deep-sea pressure.
(The deepest part of the ocean is called the Mariana Trench, located in the Pacific Ocean, a few hundred kilometers southwest of Guam. It is ~36,000 feet deep. Only three people have ever reached those depths. In 1960, Lieutenant Don Walsh of the U.S. Navy and Swiss oceanographer Jacques Piccard made the trip in a specially designed submersible called the Trieste. In 2012, explorer and filmmaker James Cameron visited solo in a 24 ft craft called the Deepsea Challenger. At those depths, the atmospheric pressure is approximately 16,000 pounds per square inch (PSI) compared to just under 15 lbs per square inch at sea level.)
The tragedy of the Titan received extensive coverage from major news organizations in America and around the world. We learned the names of the passengers, what they did for a living, and their life stories. We heard from former passengers who described the Titan submersible as shoddily built, piloted with off-the-shelf parts, including a video game console. There were reports of past structural issues and numerous former missions were aborted.
Stockton Rush, the CEO of OceanGate, piloted the Titan. Posthumously, Rush has been scrutinized for his cavalier attitude towards safety including shrugging off generally accepted maritime safety protocols. Hamish Harding was a British billionaire, explorer, and CEO of Action Aviation, an aircraft broker. Shahzada Dawood was a member of one of Pakistan’s wealthiest families and owner of a business conglomerate called Engro joined the expedition along with his 19-year-old son, Suleman. Paul-Henri Nargeolet, the former director of Michigan State University’s Center for Maritime & Underwater Resource Management, a trained professional in deep-sea salvage, Titanic expert, and the first to retrieve artifacts from the ship in 1987, was aboard.
News agencies emphasized that all the passengers were either phenomenally wealthy or related to people who were and reserving a spot on the Titan cost $250,000.
