In June 2023, OceanGate’s Titan submersible vanished during a descent to the RMS Titanic — nearly 3,800 meters beneath the ocean’s surface. On board were five people, including OceanGate CEO Stockton Rush. Less than two hours into the dive, communication was lost. At that depth, Titan faced nearly 38 MPa of pressure — around 5,500 psi crushing in from every direction. Debris was later discovered on the ocean floor. Investigators determined the carbon-fiber pressure hull had catastrophically imploded — an almost instantaneous collapse. For years, engineers had raised concerns about using carbon fiber in deep-sea pressure vessels. The risks were known. The dives continued. A mission to explore history became a lesson in engineering limits. #technology #emergency
