An experienced diver who has traveled far into the depths of the ocean to view the Titanic wreckage fears the submersible that vanished on Sunday may have imploded thousands of feet underwater.

G. Michael Harris, who said he possibly knows three of the five occupants on board the missing sub, told Fox News‘ Jesse Watters he is not optimistic they will be rescued and believes there is nothing the U.S. Navy can do.

‘Worst situation is something happened to the hull and our fear is that it imploded at around 3,200 meters,’ (10,000 feet) Harris said.

At those depths, the weight of the water would exert extreme pressure on the missing submersible – around 6,000 pounds on each square inch of its hull.

Five people were on board Titan, the 22ft craft taking paying tourists to view the wreck 12,500ft under water when they lost signal on Sunday in the depths of the Atlantic Ocean, 370 miles off the coast of Newfoundland, Canada.
