OCEAN GATE SUBMARINE IMPLOSION : What we know about catastrophic event:
The Titanic Sub Was Made Cheap—and That May Have
Sealed Its Fate:

The US Coast Guard has confirmed that the Titan submersible experienced a “catastrophic implosion” when it submerged to view the Titanic wreckage, killing all five passengers aboard.
The rescue operation continued past the projected deadline for the available oxygen supply before it was called off on Thursday when several parts of the Titan were found in a “debris field” approximately 1,600 feet from the wreckage of the Titanic at the bottom of the sea floor. Ocean Gate — the private company that offers the $250,000-a-seat expedition — confirmed that the five passengers aboard the vessel are now believed dead.
THE WRECKAGE OF WHICH WAS FOUND ROUGHLY 500 MTRS. FROM THE TITANIC.
The maker of the lost Titan submersible previously said "innovation" was the reason that the vessel wasn't classed, a standard practice to ensure seafaring vehicles are up to standards.
In a 2019 blog titled "Why Isn't Titan Classified?" Ocean Gate said its submersible had innovative features that were outside preexisting standards.
"By definition, innovation is outside of an already accepted system," the blog said. "However, this does not mean that Ocean Gate does meet standards where they apply, but it does mean that innovation often falls outside of the existing industry paradigm."
Ocean Gate also said, "new and innovative designs and ideas" on its vehicle, such as carbon-fiber material and a "real-time hull-health-monitoring system," would've gone through a "multiyear approval cycle due to a lack019 interview, Ocean Gate CEO Stockton Rush complained that regulations were stifling progress in his industry.
"It's obscenely safe because they have all these regulations," Rush said. "But it also hasn't innovated or grown because they have all these regulations."
the Titan submersible will need to be opened from the outside — the crew is locked in with dead bolts, meaning they can't break out if the vessel surfaces.
THE TITAN SUB DON'T HAVE ANY PROVISION OF OPENING IT FROM INSIDE, IT CAN BE ONLY OPENED FROM OUTSIDE MAKING IT MORE LIKE A ONE SIDE TRAVEL, FOR SURE.
Some of the equipment on board the Titan looked to be "improvised" and "off the shelf," including a video-game controller to steer the vessel.

Titan is believed to have been 3,500m below sea level when contact was lost. The vessel was so deep that the amount of water on it would have been equivalent to the weight of the Eiffel Tower, tens of thousands of Tonnes.
If there were a rupture to the structure, the pressure outside would be much greater than the one inside the hull, compressing the vessel.
TAKE A CAN OF COLD DRINK & PRESS IT, THE SAME HAPPENED WITH THE OCEAN GATE SUB.
HAMMERING NOISE WHICH THE US COAST GAURD HEARD ON THE 2ND DAY OF SEARCH WAS MOST PROBABLY FROM THE IMPLOSIONOF THE SUB.
What happens in an implosion?
When a submarine hull collapses, it moves inward at about 1,500mph (2,414km/h) - that's 2,200ft (671m) per second, says Dave Corley, a former US nuclear submarine officer.
The time required for complete collapse is about one millisecond, or one thousandth of a second.
A human brain responds instinctually to a stimulus at about 25 milliseconds, Mr. Corley says. Human rational response - from sensing to acting - is believed to be at best 150 milliseconds.
The air inside a sub has a fairly high concentration of hydrocarbon vapors.
When the hull collapses, the air auto-ignites and an explosion follows the initial rapid implosion, Mr. Corley says.
