The missing Titan submersible has been found at the bottom of the Atlantic Ocean, and all five passengers are presumed dead. The submersible suffered a “catastrophic implosion” during its voyage toward the Titanic shipwreck, killing everyone instantly.
The implosion was caused by a combination of factors, including the use of a titanium and composite carbon fiber pressure vessel. The two materials have different thermal expansion coefficients, meaning they expand at different rates when exposed to heat. This can create stress in the pressure vessel, leading to failure.
The implosion would have killed everyone within less than 20 milliseconds, and the passengers would not have suffered a terrifying and drawn-out end. A debris field of five different major pieces of debris was found on the sea floor by a remotely operated vehicle.
The Titan submersible was carrying five people: Hamish Harding, a billionaire, and explorer; Paul-Henri Nargeolet, a French explorer; Shahzada Dawood and his son, Suleman Dawood, members of a prominent Pakistani family; Titan pilot Stockton Rush and OceanGate Expeditions CEO.
The submersible went missing on June 18, 2023, during a dive into the wreck of the Titanic. A search and rescue operation was launched, but the submersible was not found until today.
The cause of the implosion is still under investigation, but the US Coast Guard said it is “likely” that the two materials used in the pressure vessel were incompatible.
The deaths of the five passengers are a tragedy, and our hearts go out to their families and friends. We hope that the investigation into the implosion will provide some answers as to what happened.
