Submersible tour boat joins the Titanic

It was painless.
So what happens when a submarine implodes?
A sub descending to the depths of the wreckage of the Titanic is under enormous pressure from the water outside. If the submarine were to implode, the hull would be crushed at unimaginable speed.
A former submarine expert explained what this might be like. Dave Corley, a retired Navy Captain, said: "When a submarine hull collapses, it moves inward at about 1,500 miles per hour - that's 2,200 feet per second.
"A modern nuclear submarine's hull radius is about 20 feet. So the time required for complete collapse is 20 / 2,200 seconds = about 1 millisecond. A human brain responds instinctually to the stimulus at about 25 milliseconds. Human rational response is at best 150 milliseconds.
"The air inside a sub has a fairly high concentration of hydrocarbon vapors. When the hull collapses it behaves like a very large piston on a very large Diesel engine. The air auto-ignites and an explosion follows the initial rapid implosion Sounds gruesome but as a submariner I always wished for a quick hull-collapse death over a lengthy one like some of the crew on Kursk endured."
John Jones, a former member of the US Navy Submarine Force, added: "Implosion events occur within milliseconds, far too quickly for the human brain to comprehend."

Somebody noted that at the depth we're talking about, if a diver's compressed air tank had a hole knocked in it, water would rush in rather than air rushing out.
Which kind of makes the lackadaisical attitude to safety even more shocking. It's like going to the moon and not worrying about safety.

He said that on Monday, when he heard the sub had gone missing, "I immediately got on the phone to some of my contacts in the deep submersible community.
So that's why I was getting so many busy signals.

Ben Shapiro: "Hard to think of a better way to undermine institutional credibility than to spend days pretending that a submersible may be at the bottom of the ocean and that the entire world should hold its breath, while knowing for days the thing imploded."

I’ll repeat what I said earlier - they probably didn’t know with certainty.

So now we know they were dead already on day 2, so what the hell was the rhythmic knocking heard after that….something else is down there playing drums….

Chinese man #1: How can we measure the US Navy's listening capability?
Chinese man #2: Blow up a submersible and see if they hear it.
Then go knock on the Titanic to see if they can hear that. -

They knew with a high probability. That's why they didn't expedite the submersible from the UK that was ready to go. At first, the U.S. said "Hurry", then turned around in a short period and said, "Standard deployment".

I agree that they likely knew with high probability. All the same, there is controversy surrounding the offer to deploy the Megellan from the onset. Seems that there was never really any hurry to have it on site and when it was decided to bring it, other technical issues ensued.

I always imagined there were people rolling their eyes at the hope for a successful rescue. I didn't know some had more information than others, but I don't think more information was ever necessary to know they were irretrievably gone. There was never a plausible explanation other than catastrophe, and there was never a plausible hope of rescuing them from 12k down.

What hasn't been covered is the fact that the Titanic tomb is like King Tut's tomb.
Woe be to those that would transgress the boundaries.
Scary. No way I would get into any sub going down to try to find the missing pancake sub. Certain death. I know of these things. For example, whatever you do, DO NOT look behind you right now. -

Damn. I couldn't help myself, and my boss was stood right there while I was reading your nonsense.

All of this talk about skipped safety precautions and such, but yet Nargeolot was perhaps the most experienced submariner in the world, particularly deep oceanic trench subs. He has made that trek numerous times on different vessels. You would think that if something looked obviously unsafe as many have stated that he would have said no to the trip…
