James Cameron on Titanic sub technology: 'It sounded bad' – video

The movie director and submersible maker James Cameron said he wished he had sounded the alarm earlier about the submersible, Titan, that imploded on an expedition to the Titanic wreckage, and that he found the hull design risky. 'I thought it was a horrible idea. I wish I'd spoken up, but I assumed somebody was smarter than me,' he said. The cause of Titan's implosion has not been determined, but Cameron presumes critics were correct in warning that a carbon fibre and titanium hull would enable microscopic water ingress, leading to progressive failure over time
