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.

A lengthy report released by the US Coast Guard Tuesday identified glaring issues with the Titan submersible and the company that ran it, a little more than two years after five people were killed when the deep-sea craft imploded on its way to the Titanic wreckage.
