A CBS article identified this company’s sub as the one involved; https://twitter.com/OceanGateExped

Fascinating theyre relying on starlink for operations. I heard starlink was fairly unreliable from folks who have it in remote areas.

One data point from me: it's not unreliable.

Two way ticket ..

Is there the option of a one way ticket? Do they drop you off in the wreck of the Titanic and leave you there?

Maybe it's for if you want rescuing from the wreck.

I wouldn’t say they’re relying on it for operations. It’s not like they doing some internet controlled submersible, it is still watercraft with someone at the helm and more than likely, they use some type of local communication for the surface crew to communicate with the expedition crew.

Not a lot of information about this one. Does the Coast Guard have a submersible of their own that they could use to recover, even if they were able to find them?

Yeah, the article is light on details. We don't know if they sank or if they're adrift on the surface somewhere after some failure. If they experienced an emergency underwater and were not able to surface, I'd fear for the absolute worst. People can survive in sunken submarines long enough to be rescued, but those are typically large submarines with multiple rooms that they can seal themselves off in. I doubt a touri…

> I doubt a tourist submarine, or really any submarine going to this depth, has multiple compartments

Indeed, from their website: https://web.archive.org/web/20230613051805/https://oceangate...

"Is there a bathroom on the sub?

There is a small toilet located in Titan’s front dome – it doubles as the best seat in the house. When the toilet is in use, we install a privacy curtain between the dome and the main compartment and turn the music up loud."

Costs about $250k per person - https://oceangateexpeditions.com/tour/titanic-expedition/ (Site looks to be down at the moment, probably overloaded due to people searching after this news). I don't think it's particularly crowded, but certainly could become one day in theory. Cached Link: https://webcache.googleusercontent.com/search?q=cache:bwPF96...

So roughly the cost of a first class ticket. (In today's dollars.)

With identical results.

The article mentions $250k/person

You're right, Google showed $125k from other articles and some looking at this earlier (a year or so ago) and $125k sounded right. I guess they doubled it!

This appears to be the vessel in question:

https://oceangate.com/our-subs/titan-submersible.html

Pressure hull made from titanium and carbon fiber, capable of diving to 4000m (13,000 ft).

I recall that one reason SpaceX switched from carbon fiber to stainless steel pressure vessels (fuel tanks) was the difficulty of detecting structural flaws.

Can any engineers comment on whether that task is easier for a vessel exposed to compression (under sea) as opposed to vacuum (space)?

How likely is a catastropic failure due to undetected flaws in carbon or composite (carbon + Ti) structures like these?
