A member of the Titan submersible's support vessel has broken down while giving evidence to an inquiry into what went wrong during the sub's voyage last year. "I knew what I was doing was very risky," said Renata Rojas during an emotional session. But, she said, "I never at any point felt unsafe."

Newly released footage shows the moment the Titan sub wreckage was found, days after losing contact with its support boat.

The U.S. Coast Guard released additional footage of the wreckage of the Titan submersible, which imploded on its way to the Titanic, killing all five people on board.
