re: Titanic tourist submarine goes missing

The failure came with not monitoring the sub after those dives. Any submersible working at those depths will be subject to deterioration that can lead to catastrophic failure....literally any of them. That's why scrutiny is needed after each dive. The accumulation takes its toll.

People who have been on working ships or even just worked around salt water ought to understand the wear and tear just the effect of salt water submersion, UV radiation, exposure to the elements, storms, etc. on any vessel.

So, folks, imagine that and multiply it by about 25 or 30 times for a submersible. Now, add in the fact that if a surface vessel suffers a power failure, it sits on the surface and waits for rescue. Might even have backup power for life support systems and, while being adrift carries its own risks, these failures that do not compromise the hull are almost always survivable.

A submersible that loses the ability to move must either:

1. Be nearly immediately rescued (or shallow enough to be rescued relatively quickly)

2. Be able to complete an emergency surface maneuver, or

3. Reach crush depth/run out of air

It's that straightforward.

I need to stop reading this thread. I’ve had My Heart Will Go On stuck in my head for a few days now.

I've had the classic "Under the Sea" from The Little Mermaid stuck in mine. I sing it in the voice of Sebastian.

Heart Will Go On is a banger - just got to load up the rock/metal remixes and covers

Have they confirmed whether a sea creature chewed up and spit out the sub?

Oh damn, they actually found it already?

but instead he was a cheap arse billionaire who risked people’s lives for what amounted to pocket change.

A passenger was a billionaire. The owner and operator of the sub was not.

Im guessing it was metal fatigue from all the dives.

You see it in a bunch of plane crashes.

Im guessing CEObro didn't want/see the need to have the scanning equipment necessary to see it with a microscope.

Instead he slapped it like a used car salesman and full sent it with people in it every chance he got.

Yep, and it was losing money even at $250k per head. People blindly assume that’s a lot of money but it’s really not all things considered for how much money should have gone into the R&D and build and maintenance of it…and there are only a couple of passengers per trip and not that many successful trips per season

Since both comms were lost at the exact same time it was pretty obvious instant implosion was the most likely scenario, glad it’s confirmed and they didn’t really have to suffer

If you've ever looked at maintenance hours vs flight hours for fighter jets, that'll give you an idea of what SHOULD be done.

It's many orders of magnitude more maintenance time than flight time.

Ah ok, cool.

Can't wait for a detailed report of what happened.
