James Cameron says coverage of missing sub became a 'nightmarish charade'

Titanicdirector James Cameron says the search operation for a deep-sea tourist sub turned into a "nightmarish charade" that prolonged the agony of the families of the passengers.

Cameron told the BBC in an interview broadcast on Friday that he "felt in my bones" that the Titan submersible had been lost soon after he heard it had lost contact with the surface during its descent to the wreckage of the ocean liner at the bottom of the Atlantic Ocean.

He said focus in the media over the next few days about the submersible having 96 hours of oxygen supply and that banging noises had been heard were a "prolonged and nightmarish charade."

"That was just a cruel, slow turn of the screw for four days as far as I'm concerned," he said. "Because I knew the truth on Monday morning."

The U.S. Coast Guard says debris from the OceanGate Expeditions submersible Titan has been found 500 metres from the wreckage of the Titanic. All five people on board are considered lost at sea after a 'catastrophic implosion' appears to have happened.

The Titan launched at 6 a.m. on Sunday, and was reported overdue that afternoon about 700 kilometressouth of St. John's. On Thursday, the U.S. Coast Guardsaid debris had been found on the ocean bed. Authorities said all five people aboard the submersible died when the vessel imploded.

Cameron, who has made more than 30 dives to the wreckage of the Titanic, said he knew an "extreme catastrophic event" had happened as soon as he heard the submersible had lost navigation and communications during its descent.

"For the sub's electronics to fail and its communication system to failand its tracking transponder to fail simultaneously sub's gone," he told the British broadcaster.

"For me, there was no doubt. I knew that sub was sitting exactly underneath its last known depth and position, and that's exactly where they found it. There was no search. When they finally got an ROV down there that could make the depth, they found it within hours. Probably within minutes."

Incident 'preventable,' director says

The filmmaker has been an oceanography enthusiast since childhood and has made dozens of deep-sea dives, including one to the deepest point on Earth the bottom of the Mariana Trench in the Pacific Ocean.

Cameron said that "one of the saddest aspects of this is how preventable it really was."

"We now have another wreck that is based on, unfortunately, the same principles of not heeding warnings," he said.

Deep-sea explorers have voiced concerns about OceanGate Expeditions' Titan submersible, saying it was too experimental to carry passengers.

OceanGate co-founder Guillermo Sohnlein told Times Radio that chief executive Stockton Rush, who was one of those on board the Titan, was "extremely committed to safety."

"He was also extremely diligent about managing risks, and was very keenly aware of the dangers of operating in a deep ocean environment," said Sohnlein , who no longer works for OceanGate.
