The 300-page report calls the implosion a "preventable tragedy" and reveals criminal charges could have followed if CEO Stockton Rush had survived.

PORTLAND, Maine — The Titan submersible disaster could have been prevented, the U.S. Coast Guard said in a report Tuesday that held OceanGate CEO Stockton Rush responsible for ignoring safety warnings, design flaws and crucial oversight which, had he survived, may have resulted in criminal charges.

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.
