Photo from submarine Titan and the pieces found on the bottom of the Atlantic, at a depth of 4 kilometers, were released by Oceangate Expeditions, determining the extent of the disaster.

According to the experts, the landing gear, a rear cover of the submarine, a porthole, the nose cone and pieces of the pressure frame were found, which confirmed the violence of the explosion.

The co-founder of OceanGate, the company that manages the submarine, said there may have been a “momentary explosion” of the vessel. Guillermo Söhnlein, who founded OceanGate with Stockton Rush, who was aboard Titan, told the BBC News:

“I know our protocol for lost communications is for the pilot to bring up the sub. From the beginning I always thought that was probably what Stockton would do. In this case, it becomes very difficult to find the submarine because the surface ship would not know that it is coming up and would not know where to look.”

“What I do know is, regardless of the submarine, when you’re operating at depth the pressure is so great in any submarine that if there was a breakdown it would be an instant explosion. If that happened, it would have happened four days ago,” he added.
