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.

The Titan submersible implosion killed all five people on board as it was taking passengers to view the wreckage of the Titanic. Now, a report from the U.S. Coast Guard says the 2023 tragedy was preventable and outlines a series of mistakes.

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.
