Really? 49 pages in?

Page 49 is my neighborhood.

This was on Reddit.

-I watched a couple of videos on youtube about this sub. Here are some highlights that might interest you:

* There are 7 playstation controllers onboard for redundancy.
* The two different beacon systems they have to communicate stopped at the same time at around 2/3 of the depth they were trying to reach. The beacons are normally not on the same circuit and one is autonomous to send out pings. The odds don't look good because both beacons stopped at the same time which is not supposed to happen even if there is a complete power loss inside the sub.
* There are seven different systems to resurface and one that does not need power or people that are alive to work. The sub IS supposed to resurface by itself at some point. It should have by now. The odds don't look good on this fact alone.
* The protocol is that if any system is showing a failure, it prompts an abort of the trip and a resurfacing. They have not resurfaced so it does not look good.
* The three main problems they can have are: 1-loss of power 2-sub integrity failure 3-entanglement. While an integrity failure combined with an implosion will kill you instantly, the two other failures would need to be combined for the sub not to resurface and lose comms. It seems likely they faced one of these two situations.
* They have to go through different complex systems for their oxygen to last to the theorical limit in time. The last step is using oxygen tanks stored on board. If they lost power, like it seems, their time is reduced by a lot...
* The sub can only be opened from the outside. Even if they resurfaced they can die of a lack of oxygen. Time is then of the essence, they have until tomorrow to be saved or face death no matter what happened.
* They usually are navigating in pitch dark with short messages from the mothership telling them where to go. It's passive navigation. They don't really know where they are at any time and recently the sub once got lost wondering around on the seabed for a while without finding the Titanic because of problems with the trajectory computing.
* It's an unregulated sub using a titanium and carbon fiber structure built with Nasa and the university of Washington.
* To do the trip, you have to sign a long waiver about the vast amount of things that can go wrong and kill you and you accept that you risk your life.
* The sub is also controlled by two touchscreens like the one in a Telsa. No direct systems, switches or panels exist to control or override anything like in a normal craft . This is not a sophisticated vessel but a very simplified one. People reported it is "hacky".
* If they are trapped at their last reported depth, they will surely die no matter what because no vehicle can operate a rescue mission at this depth.

td;lr If they survive it will be nothing short of a miracle.

Wow

The legend lives on from the Titanic on down
In the ocean they called The Atlantic
The ocean, it is said, never gives up her dead
No matter if the adventure's romantic
With a crew of 5 men, 1 toilet with them
The submersible started her journey
That shite ship and crew was a bone to be chewed
When the pressure explosion came early


I tried

I’m assuming an extremely violent implosion would knock all that out

The way they'd all fail is if it ruptured

Which would make designing a safe sub much easier than designing a safe rocket ship. Thanks for underscoring my point. A nice slow sink is way less stressful than the pogo oscillation of 34,500 kN of thrust.

No.

I would feel safer taking a 12 ft flatboat out of Cypress Cove Marina on my way to the Mars Platform than getting in a tin can sub at 14k feet

Rich dudes need to stay out of that part of the ocean
