Banging sounds heard during search for Sub

I'd be a little careful using Sub Brief as a reference.

I don't know anything about the guy I'm not using him for reference, I just think the footage of how they build the hull was interesting.

The banging every 30 minutes gives some amount of hope, however, the difficulty of the size of the search area and remaining time makes this extremely challenging.

Even if they have a cable this long, I wonder if an ROV could move the cable to attach it to the sub.

Still praying.

I would guess the main options would be to either somehow activate the Titan's own ascent controls (i.e. try to nudge the ballast release) or attach lift bags of some sort? I feel like a towed cable would be unfeasible at 3,800m.

I have no concept of the mid-water currents there, but a fair sized oilfield boat with DP out of St. John would have the anchor handling winch and Work Class ROV to drag a cable down to snatch the submersible.

Making it all happen before tomorrow morning is a bit of a stretch. Gotta find it before we recover it.

My daughter discussed with me a theory this morning that the sub was sunk by a Orca pod....

The second part of the discussion was that Elon Musk would save the day with his tiny sub...

Titan sub: What happens next after sounds detected in search

With oxygen supplies dwindling - under 24 hours' worth remains - the next few hours are critical.

Even if they could open the hatch. The pressure hull would flood. They appear to be using the pressure hull as flotation. The main reason to use carbon fiber.
It needs to be lifted clear of the water to open the hatch...
If they flood the pressure hull it probably going to sink before you can get out. You need the surface support no matter what.

It seems to me the whole design is a pressure tube with no hull piercing for wiring etc.
I think they are using radio waves to control everything by having the receiver in a separate housing just outside or against the pressure hull. (They better have at least 2 redundant systems that can take over, )

Overall from what I have seen in pictures and read it doesn't seem like a terrible design... (obviously it needs improvement)

Don't really like the carbon fiber idea.. I would prefer full titanium hull.
There's just something about steel that makes me feel better.

So, basically the hatch is the viewport at the horizontal position of the submersible?
