Doesn’t matter whether it’s a nuclear attack sub or a DSV like this. The consequences for a catastrophic failure in directional control in a submarine or submersible are equally bad. Namely - almost certain death.

Lots of people crave that ‘near death experience’ - I’m certainly not qualified to say whether Billionaires crave it more than others, but it wouldn’t surprise me.

I think it’s a bit unfair to call this a giant pissing contest. Sure, maybe it is an example of billionaires trying to one up each other. But it’s certainly also possible that these people are passionate about this stuff and have the money to actually go and do it.

I’m certainly no marine engineer (as much as I wish I would have chosen that route). But it makes sense to me that they would. Ship hulls certainly fatigue - lots of freighters have been lost as a result. And I’d certainly imagine that subjecting any structure to the rigors of the ocean - including the corrosive…

On it’s own, nothing. That’s just a way of referencing which one I’d rather not be in. What does concern me about its design is this quote:

I mean it’s done the dive before, so it was clearly capable of doing it. How the design held up after multiple 4000m dives is another matter, I suppose.

I agree that it should go to both. I was just pointing out that it probably would still have a purpose even if it was just going to the pilot. I’m guessing it wasn’t being transmitted to the ship, though - if it was, they’d be able to rule out at least some possible outcomes.

I’m not an expert in DSV design or construction, so I’m not going to go so far as to agree that this was amateurish or unsafe. But when you consider what a real DSV looks like - with it’s multiple redundancies, emergency separation systems, navigation systems, and the small matter of a design that allows the crew to…

Yeah, I think there’s only a handful of vessels capable of these kinds of deep-submergence dives. And unless things have changed recently, none of them area submarines, just submersibles designed to go down as deep as possible, maneuver a bit, and then resurface to the support ship.

Wouldn’t the purpose of the RTM be to transmit real time hull strength data to the pilot who could then determine whether to continue the dive, or abort based on the readings?

It seems what the Coast Guard is trying very diplomatically not to say is that unless this sub is found on the surface, there’s no hope of rescue.

These people were allowed to visit the Titanic, weren’t they? And not all hikers that are rescued are rescued from a place they were allowed to go. It seems the only real difference between the two is the cost it takes to go on the adventure, and the difficulty and costs associated with rescuing them - or trying to…

I mean, OK, but where do you draw the line?  Are you not a fan of government spending tax dollars rescuing a group of middle class hikers that get lost in the mountains?  

I thought the same thing - but that’s actually a shot of the vessel they use as a tender. It USED to be a Canadian Coast Guard vessel before it was sold to this company and repurposed as the surface support ship. So it’s actually not a horrible picture to use, though some explanation about the ships backstory and…

I think the only hope is that they somehow managed to resurface and are waiting to be found.  Still - how horrible would it be to suffocate to death, on the surface, because while you can see the surface of the ocean outside of the sub you can’t get the hatch open (evidently it’s designed so it can only be opened from…

“working on atrocities”

Govt decides all white people have to be slaves, you’re going to become a slave?

O......K. This doesn’t “erase” history, it stops the celebration of it - and sticks one more fork in the ridiculous “lost cause” mentality that so many southerns like to cling to.

There is literally nothing about this cite that confirms your statement.  In fact I tend to find both the writers and the commenters are suitably - if not aggressively willing to point out capitalism’s faults.  But if you can’t see the over the top absurdity of the USSR making these ecological nightmares, I don’t know…

If you’re more scared of Orcas then sharks you need to understand Orcas better. There hasn’t been one confirmed human fatality by a wild Orca. And in saying that I’m not saying that you should be scared of sharks either.
