Would you book a trip to outer space or under sea?

And add to that the pressure vessel being constructed in the shape of cylinder instead of a sphere.

You made me look.

I think the biggest variable that stacked the odds against the Titan was the fact that they created a submersible to hold 5 people "somewhat comfortably" which increased the surface area, which added additional pressure on the craft.

I don't know what I'm talking about, but help think the Alvin is one submersible that set the gold standard for deep see exploration, and it really doesn't look like a sphere to me.

Alvin only held 3 people.

Then took another look. Deepsea Challenger, which I believe holds the record for the deepest dive to 36,000' under water. The only downside? Only holds one person.

I could be wrong (usually am LOL) and sphere would make sense for a submersible craft, but I believe the issue is navigation and power to move the craft in it's design.

The Alvin uses a sphere for the personnel compartment. It was upgraded to titanium in 1973. The Evolution of Alvin

4,700 deep sea dives in 50 years.

The Deepsea Challenger also uses a steel 2.5" thick 43" sphere for the pilot compartment. DEEPSEA CHALLENGER Pilot Sphere

James Cameron has given several interviews on his views about the construction of the Titan.

.....or Musk.

Why. Musk’s company has a great safety record

I can say with 100% certainty that I'd buy a really nice cab Kubota with heat and air before I'd blow $250,000 to have a look at the Titantic.

The key word "compartment".

As I noted, it makes sense due to the pressures you're dealing with that a sphere for a compartment makes sense, but can we both at least agree that a sphere does not make the entire vessel to explore? If the entire vessel were only a sphere, I would imagine it impossible to navigate the structure where you want it to go.

No way. I am too claustrophobic to attempt anything like that.

Same here, when we were in St. Louis Missouri, I didn’t even go up in the arch, but the wife did, no way I’m riding in that little thing up to the arch.

A sphere could be designed with a propulsion system making it 360 degree manuverable.

The bigger issue is why not use a robotic system given the advances in robotic controls and camera systems?

Would you voluntarily stuff yourself into the Deepsea Challenger's 43" sphere for hours on end?

I wondered about that as well per the hatch.

The only thing I can think of was it wasn't a hatch in the traditional sense that would swing open, and that it was actually just an access point into the submersible. For whatever reason, they must have determined that it gave the structure a stronger depth rating (just a WAG on my end). I know nothing about smaller deep diving submersibles, but with the water pressure at any great depth, I can't see the hatch being opened from the inside even you wanted to open it.

I stand corrected and I was wrong.

It appears the "hatch" was the nose section with the see through "glass". It actually was on hinges and swung open.

I believe a lot of people here on this forum are in the upper percentage per annual income and savings vs the median average in the US.

That said...

Lets say you get paid a dollar for every second you work, that is $3,600 per hour.

A million dollars would require 12 days.

A billion dollars would require 31 years.

I believe everyone except the pilot of the Titan was a billionaire. I don't think a billionaire thinks in terms of what kind of machine they want to buy to do manual labor for themselves to save time, they just pay someone to do it for them

Why the heck would anyone want to dive to it now?
