would they have oxygen scrubbers??

Oxygen scrubbers? Do you mean C02 scrubbers? I have no idea. The should have something. 12 hours inside a can with five people without it wouldn't be good. I don't even know what the pressure inside the sub is. Given the relatively rapid ascent profile, I am guessing the sub stays close to atmospheric inside. If they ran higher pressure in the sub, your partial pressure O2 would be higher and your body is happy with a lower percentage of oxygen. Given what we know of the controls, I doubt there is anything they can do about that from inside. If they raised the pressurized sub, it would probably pop apart (those adhesive shell connections are dodgy against internal pressure) and everyone inside would get immediately bent (or worse depending on how high pressure was inside sub).

I think canada sent a ship with a decompression chamber to the site. I don't see many scenarios where it would be remotely useful in this case.
 
I can’t find the video I saw last night on the news. It was an old video of Rush reading a waiver-like list of all the risks on a clipboard. When he finished, he looked at the camera, laughed, and mockingly said “Where do I sign?”. Very telling of his cavalier attitude concerning the dangers and any collateral damage (bodies).

There's an interesting way to look at it. Is this just big wallet russian roulette? What if the waiver was simple? "We expect you to die on this trip, if you make it back unharmed that was luck".
 
People pay 100k to try Everest , one year a guide ( a couple ) ignored weather ( because getting people up gets you clients next yr) and people died
The Clipper round the world sailboat race costs 150k per sailor and sometimes people die . One paid Skipper had a meltdown and had to be replaced on the boat
This submersible project cost 250k and maybe so

Adventure tourism is always expensive , and often really risky .

BBC reporter at one of the press briefings. "How much food and water do they have on board". Man, that's hard hitting journalism right there. At least they may die full. I'd be shocked if water was the limiting factor and food sure as hell won't be (and the less people taking a dump in the tin can the better, if they are still alive after four days, they will basically be in a latrine).

More ROV's arriving on site tomorrow for the "search and rescue mission". They launch after the calculated oxygen runs out (and calculated by a chucklehead). Coast guard is still firmly stating that this is a search and rescue mission. Spending many millions to recover billionaires bodies isn't a good look.
 
I echo what others have said...how much is this BS costing us? Resources would be much better spent with patrol boats in the Mediterranean for the couple thousand migrants that die every summer trying to cross.

Also thought about the tow rope...then heard on the radio there are mile long fishing nets floating around down there...could easily get caught up in one of them and then it's game over...with such a small operator/viewing window it's surprising it hasn't gotten caught up in any nets before this mission. Pretty much blind down there.
 
On the other hand it is a great training mission that includes coordination between multiple service branches of multiple countries and civilian assets. Can we really put a price on that kind of training?

As an extra bonus, it takes air time (left and right) away from Orange Man coverage.
 
The longer this goes on, the more I hope it was catastrophic failure.

Slowly dying in the cold and dark does not sound fun. Could be especially bad if someone starts losing it.

That gets really dodgy. Do you take a vote to eliminate the problem? What if the problem is one of the father/son? Not a lot of supplies or space to restrain someone effectively and a breakdown uses a ton of oxygen.
 
The currents that run through that part of the Atlantic are very strong, That thing could be half ways to England or Florida by now

Which two currents meet near the Newfoundland island?


Grand Bank on the island of Newfoundland in Canada is one of the world's largest fishing grounds. It is because the cold Labrador current and the warm Gulf Stream meet at this point, and create an environment in which fish thrive.

It's built poorly enough, how long do we think before the drop weight system corrodes and releases and this tomb pops up somewhere? That would assume that it wasn't flooded. If it's flooded, the chance of ever finding this are almost zero. It took many years of hard work to find the titanic that is orders of magnitude larger and made of iron. Finding something mostly made of carbon means you accidentally tripped on it. If it's crushed, you may get lucky and find an oxygen tank that popped up at some point.

EDIT:
As for off the shelf components being better as they were tested and replaceable, one major component Oceangate did design was some sort of acoustic system to detect fatigue in the carbon shell. They didn't let anyone outside of the company evaluate it. Those that know far more about it that me said it may provide a few milliseconds of warning before you implode. Awesome.

I was thinking the same - it terrifies me even imagining their last hours down there.
If I had that type of money I'd fly to space 100%
 
I've fished off the grandbanks and also worked on offshore oilrigs off the coast. The waters in that area are rough and unforgiving even in calm weather. I don't know what kind of rescue operation they have going on, Is it radar pinging or is it underwater searching equipment?
 
I suspect they have underwater listening equipment. Doesn't appear likely that any equipment with even a hope of reaching those depths will be there before tomorrow morning (when oxygen is expected to run out).

Both. Lots of planes searching the surface. Some planes dropping sonar bouys (to listen for sure, not sure if they are actively pinging but I assume that too). One commercial rov on site (normally laying/inspecting fibre optic cable) looking underwater. Presumably, US may have tasked a sub to cruise around but no way in hell that is being publicly released. In this operation, submarine isn't a whole lot better than a surface ship as it is something like 1500 ft deep in a 12,500 ft water column. May have better sensors though.

EDIT:
Descent of Titan takes 2 to 2.5 hours. Ping was heard at 1.5 hours but not at 1.75 hours in. That puts depth when it lost contact somewhere 7,000 and 11,000 ft. That is well off the sea floor so it could have drifted a long way before hitting the bottom. If someone falls off a dock or boat and drowns, in shallowish water 90% of the time they are only a few feet from where they fell in. Currents aren't as big a factor there and they aren't descending thousands of feet.

The mother ship apparently barely knows where this thing is half the time which is how some previous missions failed to reach the wreck as they got lost in the dark. The submersible apparently has very little navigation on board. The mother ship texts them which way to head. Window only on one end with cameras to help expand environmental awareness. Wouldn't be too hard to get caught on something that you couldn't see and had zero ability to deal with.
