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.

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.
