It is notable here that the Titanic wreckage sits at a depth of around 3800 meters. As per reports, the implosion at a depth like that causes immediate crushing of the vessel and everything inside it. The pilot and the passengers would have died within a few milliseconds.
A search operation is currently underway in the Atlantic Ocean as a tourist submersible, that is used to take people to see the Titanic wreck, has been reported missing.
