News Titanic Tours Submersible missing in atlantic ocean

this sorta shit is so stupid. Logitech has little to nothing to do with this. The company doesn’t design submarine controls, the idiot that ran the racket retrofitted a controller to do what he needed.

Now is the time to capitalize and make a submarine simulator..
 
So I saw this and did not know the hull was not titanium, which is what is usually used. Josh Gates says it was an an experimental carbon fiber hull which has not been tested at those depths, under those temperatures, over a period of time with multiple launches. The hull failure theory seems even more possible now and Gates brings up something else in the video which is that there might have been an electrical fire. My God, the irony of dying to an electrical fire at the bottom of the ocean.

If you don't think carbon fiber is a good material for pressure vessels, you might be concerned that the hydrogen powered vehicles on the road use carbon fiber tanks to contain hydrogen at pressures between 5,000 and 10,000 psi.

They are also used for Compressed Natural Gas CNG at 3,600 psi.

Oh I do think that COPV tanks at massive pressures are risky items. It's basically a small bomb.
Carbon-fiber is tricky stuff to work with, it's not inherently uniform, it can easily have weak-spots in it and it can fracture and tear. A lot of it's strength depends on careful manufacture and baking in an auotclave.
For a deep-dive sub like Titan I do believe it was the wrong choice of material and i'm not saying that after the event like a wise-ass, i stated that yesterday. I do have some knowledge of material science and such like.
 
The US Coast Guard says a debris field has been found near the Titanic as rescuers search for missing submersible Possible implosion.
 
So are they basically starting to hint that the debris field they found is the sub?
 
If the sub drops more or less vertically through the water the first thing I’d think about is having some kind of winch/ tether system attached to the sub from a surface vessel. Wonder if that wasn’t a possibility or wouldn’t have worked?

They wouldn't be holding a press conference to announce they found a bunch of unrelated trash. It imploded.
 
Logitech is always ahead of its time. I have their Harmony remote and it turns on/off all of my entertainment devices at once.

Not surprised it’s using for Titanic expedition at all.

They want to fly around the Titanic and it's debris fields. A tether gets risky as it could get entangled.
 
I guess the titan being grounded the last 3 missions because of worries regarding structural fatigue may well be telling.

So the banging could well have been entirely erroneous.

I'm shocked the sound of an implosion wasn't heard.
