The boy isn’t 4. He must have asked to go.

19 year olds are notoriously great at risk assessment and their deep understanding of their own mortality.

This isn’t your typical 19 year old hanging out at the mall. For these kids and families life is a series of never-ending adventures. Their risk assessment meter is in a different scale.

More about Nargeolet, he's gone down the wreck site 35 times.

Which undoubtedly made it feel safe to him (that is how risk perception works), and likely his companions.

Really?? What an awful design flaw.

Why? It's not like they could open it, exit, and swim to the surface.

Seems like a necessary design. If they were the other way, perhaps the pressure from the ocean could press inwards and “unscrew” them. Then everyone definitely dies. Bolting from the outside in means the pressure strengthens the bond.

I think the water pressure is so powerful that buoyancy is negated and, therefore, any type of debris field doesn't exist. The water current and pressure doesn't allow anything to just float away.

But the debris from the titanic are still there. Made of much less space age material.

Titanic was open to the water from the time she began to sink, so there was equal pressurization inside and out - that is why she is still intact so many years at 12,000 feet of pressure. Totally different situation to a submersible that experiences rapid depressurization at depth.

After reading that mythbuster thing quoted above I am now terrified to let my teen go scuba diving. That doesn’t actually happen does it? How deep do scuba divers usually go?

PADI certified diver here - most recreational scuba diving is limited to maximum of 130 feet, and that's after specialized training. Open water certification involves diving at less than 100 feet.

It is still possible to get very sick and die from the bends if the diver ascends too rapidly, but the risks are much lesser in recreational diving depths than for technical divers who go down as deep as 350 feet.

Scuba is an incredible experience and one of the best things I've done in my life. I would not hesitate to recommend it, but would certainly caution to learn from and dive with responsible risk averse people.

Yeah, seems like a bad idea. I would not be a hard no at anything bolted from the outside. Seems too much like a coffin.

There's no way you could get me into this tube even if it was on dry land:

There are 5 people in that thing???

Perhaps they need to reassess risk.

+1 22 ft. One toilet. No seats. Water exerting 6000 pounds of pressure per square inch so it could implode. Can't launch itself like a submarine. NO thank you!!

Drinking your own urine would give you another day or two.

But it’s moot point, as all signs point to a sudden hull collapse.

The submersible has a relatively novel hull of titanium and carbon fiber. Given the brittle nature of carbon fiber, I suspect the monitoring for defects isn't well understood at this time for this application.

I'm wondering if the repetitive stress of multiple dives means the submersible has a distinct and measurable shelf-life. Eg, the materials could only do the dive a max of 60 times before it eventually had a catastrophic failure.

If that's the case, then the organizers are under-charging clients at $250K.

It will be interesting to see if they ever find the wreckage. I would imagine that a hull breach would lead to an instant scattering of equipment and the pressure would crush any pliable materials into microscopic particles. There may not even be a noticeable wreckage to evaluate.

Carbon fiber is notorious for developing cracks when it's used for bike frames and bike forks.

But Boeing makes wings out it so therefore this is a solved problem. /s

That’s a lot of people! The place is going down the tubes.

Yeah, pretty soon it'll be just like Venice.

Not a boy, but a young Man.
