Finding reported in the NTSB final report on the hull failure and implosion of the Titan submersible.
A 2025 NTSB report found that pre-existing delaminations and additional damage to a carbon fiber composite pressure vessel sustained during earlier dives can further deteriorate and weaken the vessel, potentially producing a local buckling failure that can lead to implosion.
