That.

I do not get how there is no backup/rescue vehicle at all? Ok sure the people going down to watch signed some paperwork listing all the risks, but.. can't mankind do better?

CBS journalist David Pogue was invited to travel on OceanGate's Titan submersible on a press trip last year, to reach the wreckage of the Titanic.
He told the BBC that passengers were sealed inside the main capsule by several bolts that were applied from the outside and had to be removed by an external crew.
He said he initially thought the sub seemed improvised: "You steer this sub with an Xbox game controller, some of the ballast is abandoned construction pipes."
If the sub became trapped or sprung a leak "there's no backup, there's no escape pod", he said.

No chance I would have gone aboard that.

Hate to day it, the submarine appears to be made of scraps with some new parts thrown in. There was no means for surfacing in case of an emergency. In short, this was a coffin in the making.

There is no rescue. Titan ‘was’ a 5 inch thick carbon fiber tube the crew enters then an end cap with the window is bolted on with 17 bolts locking the crew inside. It takes around 90 minutes to get to the Titanic wreck, Titan was an hour and 35 minutes into the dive when communication was lost. At that depth all it takes is one over threaded bolt and <POOF> it’s gone in less time it takes to blink your eye.

Compare it to James Cameron’s Deepsea Callenger and Titan looks like someone’s backyard project put together with bubblegum and baling wire.

Btw, a U.S. Navy rescue sub is limited to 2,000 ft depth.

"X Box Game Controller."

There is a reason why even a simple flip switch or a simple to-press-button for airliner cockpits cost several hundred dollars per piece.

And back in the late 90s when I had a PS1, one controller for it once stopped working in my hands while playing. Just so, out of the blue. Never came online again.

The whole concept for that "submarine" sounds incredibly irresponsible. German newspaper said that passengers must sign statements that they understand that the boat is unlicensed, has not undergone any technical inspection, and that the operator cannot be held responsible for any damage to passengers, injuries, psychological traumata and stress consequences.

Who wants to dive in such a thing - and even pays for it...?

It is incredibly irresponsible! These people signed their own death sentence. Such a shame.

Even though the sub should have been sending signal to it's mothership on the surface.

Speaking of his experience, Mr Pogue said: “It's about the size of a minivan… There's a rudimentary toilet, which amounts to little more than a couple of ziplock bags. And of course, they all brought snacks.”

He said a lot of the interior of the vessel would “sound very janky to a lot of people — a lot of this submersible was made from off-the-shelf improvised parts.”

He went on: “For example, you control it with an XBox Game Controller. Some of the ballast are these abandoned lead pipes from construction sites and the way you ditch them is everybody gets to one side of the sub, and they roll off a shelf.”

However, he added: “The guy who built the sub told me yeah, that stuff's all kind of janky but the important thing, like the capsule that contains the people in the air, that was co-designed with NASA and the University of Washington. The part that keeps you alive is rock solid. ”

Another scenario is a leak in the pressure hull, in which case the prognosis is not good, he said.

He explained: “If it has gone down to the seabed and can’t get back up under its own power, options are very limited.

“While the submersible might still be intact, if it is beyond the continental shelf, there are very few vessels that can get that deep, and certainly not divers.”

Even if they could go that deep, he doubted they could attach to the hatch of OceanGate's submersible, which is made of titanium and filament wound carbon fibre, and which weights 20,000lbs when out of the water.

Just the ziplock bag toilet

with curtain would have precluded my indulgance; along with eight hours spent on these old knees...

Then again, nuthing "cutting-edge" for it's time goes outta style...ie: CSA Hunley 1864>

Exactly. Just crazy that the builder thought it was a good thing to brag about, a off the shelf game controller that was meant as a toy.

They keep talking about locating this sub, so... what's the plan if they find it? Lower a crane hook and reel it in?

I read several times where the builder said there were 7 ways to achieved positive buoyancy and get to the surface. So, did they all fail? More likely a pressure hull or hatch failed and the crew was wiped out instantly.

Even if the sub was to managed to get to the surface but isn't located for a while, do they have any way to access fresh air? My understanding is the only access hatch is bolted tight from the outside... so even if it was discovered on the surface, someone better get there quick with a wrench.

It would be crazy if the sub was to miraculously pop up on the surface...

Well, there goes my lifelong ambition to to spend $250,000 to stare at bits and pieces of the world's most heavily studied and photographed shipwreck in a shoddily constructed and unregulated submersible with a safety factor of 0.4.

I think these Rescuers and the Media should stop clutching at straws and tell it as it is, giving their families false hopes when they're already dead is just prolonging the agony for them.
I don't know who's going to raise this issue first but it needs to be told and fast, the chance of them being rescued is a big fat Zero and this is not a rescue mission anymore as its now a recovery mission.

Fifty year old white guy submariners are not inspirational? So hire a bunch of unquestioning kids who will do what they’re told and don’t really know any better instead. It’s obvious this CEO didn’t understand the dangers involved.
