In a strange sense, it is also like the final scene of the HBO series The Sopranos, where one moment they are dining, and the next they are gone.
We are occasionally reminded that nature must be taken seriously, whether you’re scuba diving, mountain climbing or playing with predatory animals. The forces of nature, including the laws of physics, are not under man’s control.
I keep hearing “It was quick!” proclaimed. Well except for the days leading up to it knowing it was imminent. Guess being trapped in a tiny space knowing you’re doomed isn’t that big a deal to some folks.
And never will be. If they are, the families of the victims of MH370 will be heard from I'm sure.
It’s something like a fly swat.
When it’s your time to go, you’re gone. One minute you’re a billionaire enjoying all the world has to offer. The next, you’re a spirit on the other side wondering, I thought I’d get more time.
Retire ol’ Sparky and set up a “sight seeing” tour for prisoners on death row. Two nanoseconds. No pain at all.
Now that the media has accepted the truth, the writeups are getting quite ridiculous, but the analysis of 'nanoseconds' is fairly astute: If all they experienced was a flash of light (likely) before their skulls exploded, they were quite fortunate. They probably won't find anything larger than a hip socket.
Trying to get my aged mom to understand, I told her:
Imagine 5 beets in a can, run over by a steamroller. Yes, that flat, that squishy.
Light travels approximately 1 foot/nanosecond.
Unless it implodes. And steering it with a $40 video game joystick probably didn't help matters.
It irks me when "experts" use language in non-nonsensical hyperbolic ways.
It takes much longer for a vehicle at the depth mentioned than two nano-seconds, and much, much longer than four nanoseconds for the event to register to your brain.
Consider, realistically, how long it would take the submersible to implode. The pressure outside was about 6000 psi greater than inside the submersible.
The submersible was about 7 feet across inside. Assume the walls have to move in only 18 inches to kill everyone. Starting from zero, at about 20,000 psi, a bullet takes about 2.3 milliseconds to accelerate and exit an 18 inch barrel. The pressure is still above 6000 psi when the bullet leaves the barrel. Higher initial pressure, unidirectional, 18 inches travel 2.3 milliseconds. The implosion will take longer.
2.3 milliseconds is 2.3 million nanoseconds.
Nerve impulses move, at the most, at 400 feet per second. Assume minimum length of sensor to brain of 1/3 foot, then the impulse would take 1/1200 of a second, or .833 milliseconds. Perception takes much longer than mere transmission. Images have to be processed, as do all nerve impulses. Perception, as measured by reaction, takes much longer, on average 200 milliseconds.
200 milliseconds is 200 million nanoseconds.
I wonder how long these stories are going to continue. We now know the people died in the sub when it imploded. 30 or 40 years ago, that would have ended the story. But in our content-driven media world where there are hundreds of news sources with an insatiable need for content, we get stories about how it must have felt like when the sub imploded. This isn’t news. Its macabre clickbait. They were thrill-seekers taking a significant risk that turned out catastrophically bad. End of story.
They were dead before anybody knew they were missing. Never knew what hit them.
Imagine that little sub with a block of lead the size of the Empire State building sitting on top of it. That's the weight of two miles of ocean.
Does CF creak and groan when under pressure?
Did they hear noise of impending doom?
Every time that I have been seriously injured, typically I have not realized what a mess that I have made out of myself until the adrenaline starts to wear off. Depending on what you are concentrating on there is a period of time before you realize the sensation that you are experiencing is pain.
If you know something is hot and you cautiously touch or put the back of your hand near it to gauge just how hot it is, you can pull your finger or hand back before you are seriously burned. But if you inadvertently grab something very hot you will often not let go until after you are seriously burned especially if you are concentrating on something else.
This discussion about the nanoseconds it takes for your nerves to report back to your brain is a little silly. There is a much larger time period before your brain realizes what is going on after it receives signals from your nerves.
Also, my crews and I responded to many seriously injured people who were still alive and conscious when we arrived. Serious trauma and pain causes people to go into shock and they often cannot tell how serious their injuries are. So, we would be asked, “Am I going to die?” sometimes fairly calmly. A person’s expectations can affect their outcome, so we would almost always respond, “No, you are going to fine.”... even when we knew that they were probably not going to make it.
On a interesting note:

Seems like no one is talking about the toll the compression and decompression cycles had on the hull integrity. The sub took a few trips so there was probably a weak point which developed in the hull. ...could have even been some amount of ultraviolet ray and salt water weakening of the hull materials while sub was topside or in the water. Needed more white 50 year old engineers, corrosion experts and deep dive masters. Still a sad way to go....however quick.
The Titanic’s debris field is scattered about but generally at a depth of about 12,500 feet. That makes for about 5700 psi water pressure on the hull. It would be like being killed in a (very fast moving) hydraulic press.
Maybe the Gorilla Glue gave way on the front hatch.
