Five people died when OceanGate's Titan submersible catastrophically imploded during a deep-sea voyage to the Titanic wreckage in 2023.

A U.S. Coast Guard report found the OceanGate Titan submersible implosion was preventable, citing design flaws and safety oversights. Stockton Rush, OceanGate CEO, was determined to be responsible for ignoring warnings and regulations, leading to the fatal incident.

Multiple contributing factors — including OceanGate’s toxic workplace environment and profit-over-safety ethos — led to the entirely "preventable" implosion of a submersible that killed five people off Newfoundland two years ago, Coast Guard investigators said Tuesday.
