James Cameron draws parallels between Titanic and sub tragedy.

James Cameron, the director of Titanic, has said he felt the loss of the Titan submersible "in my bones" after it went missing on Sunday. Cameron, who has completed 33 dives to the wreck of the Titanic, suspected a disaster when he learned that the sub had lost both its navigation and communication at the same time. An official from the US Navy has said that the navy detected "an acoustic anomaly consistent with an implosion" shortly after the Titan lost contact with the surface. The sub was found on Thursday after a remotely controlled underwater vehicle was deployed.
