Knew submarine must have imploded like 10 cases of dynamite going off: 'Titanic' maker Cameron

'Titanic' director James Cameron said he knew the Titan tour submersible imploded after it went missing. "We got a confirmation within an hour that there had been a loud bang at the same time that...comms were lost. I knew what happened. The submersible imploded," he said. He said implosion may have been like "10 cases of dynamite going off".
