Submarine Tour to Titanic Missing

It may be passed the point that they can be saved even if they found their general location right now. Going on the premise that they have 20 hours of air left, they would still need to get the equipment to the area and drop to the bottom, so that is 3+ hours. Then they need to find their exact location on the bottom in pitch black. The lights they have don't penetrate the water very far. Even when looking for the Titanic, it can take hours scouring the bottom to actually find it, and that is a massive ship, so say another hour looking. Then assuming they have the right equipment to attach floats or hook up some kind of tow cable, maybe another hour of doing that. Then another 3 hours to rise to the surface. That would basically mean they have about 12 hours from now. And that is the best case scenario.

It was also reported that the original 96 hours was a best case assuming normal breathing and that each individual has average oxygen consumption, but it could be as low 70 hours.

Unless they find them on the surface, or somewhere in the middle of the water column, that could change things obviously. It's also possible that one or more might already be dead, perhaps from cardiac arrest due to the stress.

It's also possible that if it is on the bottom, that it didn't land completely flat because the ocean bottom isn't an even surface. If it landed vertically or even at a slight angle, one or more could have suffocated just from having people on top of them or being wedged tightly together.

Imagine yourself in that situation.

Not a good way to go, but they shouldn't have gone in a POS homemade sub with no certification of any kind.

If they did any sort of research and also had any common sense, they'd neve have gone near the place.

There is risk taking, and then there is sheer stupidity.

An expert on CBC yesterday suggested that if the sub lost power it would sink to the bottom like a rock. He also had some items, a coffee cup filled with paper towels that they take down with each expedition to show the before and after of the compression that occurs.

I don't expect them to be found at this point.

The problem is that the documentaries that are going to come out in the next 10 years about the disappearance are all going cause the algorithum to recommend stuff about that Malaysian airlines flight that also disappeared.

It's a much smaller search area, but also a much smaller vehicle. Estimated depth roughly the same? 4k down?

Fewer people interested, but I guess much richer estates to continue private efforts.

Profile picture? Appropriate.

My wife is learning German, so I watch it with subtitles(probably the best way).

Well, now I know what I'm doing after work!

This is just stupidity in design if it’s true. Part of safeguarding this should be automatic dropping of ballast on loss of power.

And if it lost power and automatically came up to the surface you're going to get Nitrogen narcosis and go out that way.

He said there was a "limit" to safety, telling Pogue: "You know, at some point, safety is just pure waste. I mean, if you just want to be safe, don't get out of bed, don't get in your car, don't do anything. At some point, you're going to take some risk, and it really is a risk-reward question."

Why? Maybe I’m missing something but isn’t the pressure in the cockpit essentially atmospheric so you don’t get compression of air which leads to nitrogen narcosis?

Apparently the tracking device has surfaced.

The guy sounds like one of those crypto bros you hear about. Able to suck people in with their air of confidence.

Just listening to the BBC livestream, and the expert on said that because a vessel like this will likely glide as it falls and also considering currents, the sub could be 15-20 km away from the original surface location, in any direction. That's a huge area to have to look in such a short period of time, especially considering that very few vessels or equipment in the world can actually go that deep.

Come on, nitrogen narcosis is kinda fun, like being drunk. I enjoyed a bit of it diving in Minnewanka. What you are worried about is "the bends," which is nitrogen gas bubbles in your blood expanding as you rise, then popping all the soft bits in your body. Narcosis can be deadly, but it happens at depth. But becuase this sub is pressurized, neither should be a factor.

The vessel was designed to corkscrew down, and becuase it seems to have made it to 1750m OK, it probably wouldn't have drifted that far in the remaining decent. Presumably an emergency surfacing would be fairly vertical.

Hi fellow "got narc'd at lake Minnewanka" buddy!

In a loss of power situation, would dropping the ballast be enough?

Maybe a stupid question, but I've been wondering if the sub would surface without power? Or does the pressure at these depths override any buoyancy?

Hopefully they had helium escape valves on their watches is all I'm sayin'.
