The Catastrophic explosion of the Titan submarine, the wreckage of which was reached

The tourist submarine Titan, which went missing while diving in the wreckage of the Titanic, exploded "catastrophically" and broke into pieces, US Coast Guard officials said.
"The wreckage is consistent with a catastrophic explosion of the watercraft," Coast Guard official Rear Admiral John Mauger said in a press release in Boston. So we will continue to work and search the area below."
Mauger reported that the accident occurred 1 hour and 45 minutes after the Titan submarine dived, when communication with the vehicle was lost.

Stating that they believe that all those on board the submarine are dead, Rear Admiral noted that they found the wreckage of the tourist submarine 488 metres from the bow of the Titanic, which sank about 100 years ago, at a depth of 4 kilometres from the surface.
