According to independent.co.uk, James Cameron revealed that he knew highly sensitive information about the Titan submersible search and rescue mission days before it was released publicly.  Cameron was aware that top secret US Navy listening devices had detected an implosion near the Titanic wreckage within an hour of it occurring on Monday, and has since described the search for the five crew members as a “nightmarish charade”.

The 68-year-old Cameron told ABC News that his contacts within “the community” had shared details of the mission with him, a reference to the small and close-knit submersible Manned Underwater Vehicle industry. 

As published on insider.com, Cameron, who has visited the Titanic wreckage on 33 different trips, said that he warned OceanGate officials about faulty vessels ahead of the trip and that it was "only a matter of time" before disaster struck. 

In 1995 Cameron was on his third submersible dive with Russian pilot Dr. Anatoly Sagalevich and a Russian engineer filming for "Titanic," when a sandstorm created by currents tailing from the Titanic's shipwreck grounded their vessel on the ocean floor, Radio Canada reported.

"Anatoly said, 'Oh, no,' something you never want to hear a pilot say, and we locked eyes for a second," Cameron said in the book, per Radio Canada. 

With their battery losing power, and in frigid temperatures, Cameron said his crew attempted to abort the mission and travel back upwards twice, before being pushed back down by the deep sea currents.  On their third try after a half-hour of being stuck, he told Radio Canada they had been pushed far enough away from the sandstorm to safely make their way back up.
