The Titanic

As soon as you cranked one of the bolts even half a turn you would likely be crushed to nothing
That's probably why the option to open from the inside wasn't an option when the thing was designed

At 3800m depth you are looking at a pressure of about 2.5tonnes per square inch. So the perspex screen would have to withstand about 1200 tonnes if it was circa 24inches in diameter. Which would appear to be roughly right size wise. Opening outwards means the pressure is not on the bolts it's on the screen and hull and distributed evenly, so engineering wise it's by far the best method.

You could engineer it to open outwards and be operated from the inside like a larger submarine?? but that would cost more as its a more complicated design.

Billionaires stepson seems gutted.
I'm sure he was staying in touch with the search while he was there........Watching, waiting, commiserating...

There is only electrical connection between inside and outside the chamber. Anything else would be too much of a weak point. So any systems have to be electrical / no manual system to ditch the balast.

But you would think they would have 2 or 3 separate independent systems that would be able to bring it back up and they should have a last resort one on a timer that just forces it up after 24hours. I did hear it had a timer based system but obviously its not worked.

You get the impression 1 battery feeds it all - system goes down and thats it.

They’ve already slagged off the sub itself as been a bit basic, it’s controlled with an Xbox controller, although these days they use them with drones. Sky currently talked 20 mins about the debris field talking absolute shite.
 
US Coast Guard saying debris found.

What could the debris field could be​

This report carries huge caveats.
It may be something, it may be nothing.
But the US Coast Guard has not posted many tweets over the past few days, so it may well be significant.
Speaking to experts this week, many worried that the Titan may have suffered a catastrophic implosion as a result of a hull failure.
Such a scenario could explain the debris. But, again, this report may turn out to be nothing.
The seafloor around the Titanic wreck is littered with all sorts of debris, not least from the great ship itself.
