The US Coast Guard had been searching beneath the ocean floor with remotely-operated vehicles (ROVs) while sonar — from planes overhead, buoys on the surface, and expedition ships — pinged the bottom of the ocean looking for signs of the sub.
However, on June 22nd, the Coast Guard reported an ROV found debris from the Titan about 1,600 feet from the bow of the Titanic. This led search crews to believe that the sub imploded shortly after its departure, killing all five passengers.
The sub carried 58-year-old British billionaire Hamish Harding, who flew on a Blue Origin suborbital flight in June 2022, Pakistani billionaire Shahzada Dawood and his son, Suleman Dawood, a 77-year-old French explorer named Paul-Henry Nargeolet, and the CEO of OceanGate, Stockton Rush, who was 61 years old.
The Titan was a small, five-person submersible that is designed to reach depths of 4,000 meters “for site survey and inspection, research and data collection, film and media production, and deep sea testing of hardware and software,” according to its operator OceanGate.
On the inside, it was little more than a tube with a single viewport, a small toilet, touchscreens for viewing sonar and controlling the sub, as well as a screen for viewing the external 8K camera’s feed. The “experimental vessel” was also controlled by a Logitech game controller. Eight-day trips, including the submersible dive to the Titanic, cost a reported $250,000 per seat.
