Submarine bound for Titanic goes missing

I don't know if I could ever go into one of those small submarines even though I'm not claustrophobic. It's just something that I can't even compare anything else I've done to so not sure how I would react.

I must admit though, to have the means ($$$!) to see something like the Titanic up close would be pretty cool.

I had it in my head this was a drone. I was wondering what all the hubub was about. Can't these people just watch avatar in vr and save the trip?

Being there gives people the sense that they are part of the event. Like climbing Everest.

Two things I would never do.

This should be an interesting TSB report.

Who's on board the missing Titanic submarine?

Some quite prominent people are (or were) onboard this sub.

Time is running out and still they haven't located it...

Odds are the sub probably imploded and they all died instantaneously. 6500 pounds per square inch of water pressure doesn't take any prisoners.

They did test it to that depth but as Arron pointed out there he did not see air scrubbers so they may have burned to death ala Apollo 1.

Lets say for a second, they did not implode or burn to death, or meet some other grisly fate, lets say they are alive (they're not, but lets pretend) and sitting on the bottom, how do we get them off the bottom, 12,500 feet from the surface?

Their ONLY hope at this point is they lost comms and surfaced and are bobbing on the surface.

If they are anywhere else they are dead as there is not a platfom that can handle the amount of cable required to reach them and a sub rescue without means of docking is out of the question.

Only the US Navy, or maybe the Royal Navy, would have the deep rescue technology to pull it off. And then again it's entirely dependent on the rescue vessel actually knowing exactly where they are and then on top of it being able to get there on time. Even a thirty-five knots it's going to be at least a couple of days to get there from either Britain or the US. By then, even if the sub hasn't imploded, they'd be out of their supply of breathable air.

It's an interesting what-if scenario but every single conceivable odd is against a happy ending. This sort of rescue makes the trapped Chilean miners or the rescue of those Asian boy scouts from the cave they were stuck in look like easy scenarios by comparison.

A company running this sort of undersea adventure certainly isn't running it on a shoestring budget. But it appears they regarded it as something routine when each and every single tour to the Titanic is fraught with high chances of disaster. Even the best welding in the world, which submersible vessels usually have, is subject to massive stresses from repeated immersion to highly elevated levels of water pressure - one sudden hairline crack in a weld and it's the end for that submarine. Even today most nuclear naval submarines that are built to one of the toughest construction codes ever developed don't submerge beyond several hundred yards of depth simply because even to navy vessels it's still too dangerous - really deep dives are the exception, not the rule, and are done only out of necessity (like in training operations with a rescue ship nearby) and aren't part of the sub's regular routine. For a civilian-built and operated vessel? I'm not saying these guys are greedy, despite the cost of the tour, but they were most likely running with a starry-eyed business plan and probably began to believe after repeat trips with no issues that the danger had become remote.
