Titan submersible

The Coast Guard completed its hearings on why the Titan submersible imploded last year as it was taking passengers to view the Titanic, killing everyone on board.

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.

OceanGate co-founder Stockton Rush said the carbon fiber hull used in an experimental submersible that imploded was developed with help of NASA and aerospace manufacturers, but a NASA official said Thursday that the agency had little involvement and a Boeing official said some recommendations were ignored.

The carbon fiber hull of the experimental submersible that imploded en route to the wreckage of the Titanic had imperfections dating to the manufacturing process and behaved differently after a loud bang was heard on one of the dives the year before the tragedy, an engineer with the National Transportation Safety Board said Wednesday.

Close friend of OceanGate CEO testifies about test dive that left him "unnerved" as Coast Guard tries to determine the cause of Titan submersible implosion last June.

The co-founder of the company that owned the experimental submersible that imploded en route to the wreckage of the Titanic told a Coast Guard panel Monday that he hoped that the silver lining of the disaster will inspire a renewed interest in exploration, including the deepest waters of the world's oceans.

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.

Two more witnesses testify in Coast Guard hearings into Titan submersible implosion, at times contradicting safety concerns revealed by others.

A former employee of the company behind the Titan submersible that imploded last summer says he warned years ago the experimental vessel wasn't safe.

In North Charleston, Coast Guard investigators call witnesses in their two-week long hearings into why the Titan submersible imploded killing five people.
