A paid passenger on an expedition to the Titanic with the company that owned the Titan submersible testified before a U.S. Coast Guard investigatory panel Friday that the mission he took part in was aborted due to an apparent mechanical failure.
The Titan submersible imploded last year while on another trip to the Titanic wreckage site. A Coast Guard investigatory panel has listened to four days of testimony that raised questions about the company’s operations before the doomed mission.
