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.

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.

A report on the death of five people in the Titan submersible blames design, maintenance, and inspection flaws for its failure. “It all came back to Mr. Rush,” the head of the investigation told WIRED.
