“All good here.”

Those were some of the final words that the doomed Titan submersible crew communicated before the submersible imploded on its mission to the Titanic wreckage site in June 2023.

The message, revealed as part of the Coast Guard’s Monday hearing into the circumstances of the failed mission, was sent to support vessel Polar Prince on June 18, 2023, shortly before thesubmersible imploded, killing all five of its crew members. It was an incident that captivated both sides of the Atlantic as crews made a mad dash to save the crew after the sub lost contact with the surface - with the world unaware that the lives had been lost.
