The operator of an experimental submersible that imploded while seeking out the sunken Titanic was either putting profits over safety or pushing humankind’s boundaries.

Two weeks of testimony suggested the company responsible for an experimental deep-water submersible that imploded, killing five people, either recklessly ignored warning signs in the name of profits or represented the nation’s explorer spirit in taking calculated risks to push humankind’s boundaries.

Those contrasting viewpoints emerged as the Coast Guard panel tasked with determining why the carbon-fiber Titan was lost 12,500 feet (3,810 meters) deep wrapped up testimony Friday with new information that could have changed how rescuers responded and more discussion of the company co-founder’s cavalier attitude.

Capt. Jamie Frederick, commander of the Coast Guard sector based in Boston, appeared surprised to learn that the crew of Titan’s support vessel, in hindsight, felt there was a slight shudder around the time the submersible imploded on its way to the wreckage of the Titanic last year.

Frederick said it was “unconscionable that they wouldn’t share that” and it could have changed the rescue response. “It certainly would’ve changed the equation,” he testified.

Also Friday, an OceanGate employee testified that he resigned after a “tense” conversation in which co-founder Stockton Rush told him the vessel would be flagged in the Bahamas and launched from Canada to avoid U.S. scrutiny — and arrogantly brushed aside U.S. regulatory concerns if it went to a U.S. port.

    The issue is that carbon fibre is strong, hard, but brittle. When it fails, it fails catastrophically. It also doesn’t show many/any signs of failure, till it fails.

    A carbon fibre hull, under those loads, could be good for 5 dives or 100, depending on the vagaries of how it was made. It won’t show the wear, until it fails. That is why most companies won’t trust CF under those sort of loads.
