There are some pretty disrespectful comments in this thread. Some of you should be pretty ashamed, these guys have familes.

I couldn't imagine having to speak to my son like the father and son would have had to if of course they were/are still alive.

It would almost be better that the sub just imploded very quickly.

I don't see many disrespectful comments tbh and I consider myself a bit of an internet disrespect police officer. A few cheeky jibes but that's to be expected, people handle these things differently.

Yeah I have read similar things, it's amazing stuff *one* time, there is a reason F1 car bodies rarely last more than a couple of races & have several replacements handy.

Once CF goes, it's gone, literally as useful as a wet flannel.....also it's only strong in one direction (of the stitching), once you get forces in any other direction, its very weak, something similar to plaster like you put on broken arms.

I was under the impression the pressure hull was titanium and the outer white bit was carbon fibre so not meant to withstand pressure.

Don't worry I doubt the family are reading this thread.

It was a tube made from 5inch ish thick carbon fibre with titanium mounting collars glued to either end and half hemisphere titanium pressure hulls either end, one of which housed the window iirc

Edit : actually I might be wrong, that vid below is for cyclops and not titan, anyone know how the titan was made? Was it made in the same way?

Edit 2 : So the titan is a cyclops class, so presumably that vid would be how it was made or very similar.

I could easily see a situation where they've skimped on the O2 and know for sure that it was over hours ago but can't obviously admit to it. If that's the case then it may even be feasible that they know where it is but can't say as then it would be investigated by third parties and anything amiss would be rather obvious.

Probably just incompetence, but society's been weird lately so I'm not quite capable of parking this insane thought in the garbage bin.

They'll pop up with an hour to spare with some concocted story that's easily converted into a movie script. The banging is probably a typewriter they have on board for writing it.

Morbid question, assume they are still alive & decide it's time to start reducing the numbers of crew.....how would they do that down there with little options? But then, would it even work? Because I'd assume a decaying body would take up some oxygen too, and really, how much longer would the air last if there was just 1 or 2 of them?

Probably too late for that now anyway but I doubt the CEO is popular on the sub right now if you wanted a first target...

Apparently all the protocols have been followed yet the equipment to deal with an accident is still on route to the area. More work needed on them protocols me thinks! That CEO has likely been advised by their lawyers not to say anything too specific that would risk his rear being sued any further in to oblivion than is already likely.

Short of having a few billion dollars worth of equipment much closer all the time there is a good chance miracles have been permformed to get stuff there as quickly as it has.
This is all quite specialist equipment that is normally pretty busy with tasks that are often booked months or years in advance and not a great deal of it in the world because of the cost and expertise needed to operate it.

Ships, especially large research ones and those designed to operate things like underwater ROV's tend to be big and not exactly speedy. Even the likes of the US and British navy who from memory have "rapid deployment" rescue subs that are designed to be loaded onto an aircraft to reach the rough area they're needed still require a ship that can carry them to the site, and those ships are usually quite limited in speed. So unless you have a ship with all the necessary rescue equipment basically following you, you're always going to find it takes several days to get equipment to remote locations unless you're lucky and you've got one that is within a few hundred miles and ready to go.

It's one of the reasons the likes of the sonar bouys will have been deployed by the aircraft, they can start looking for signs of it long before the equipment can reach the site, and if they think they've found it the equipment can be deployed very quickly (the chances are all the ships heading to assist with ROV's are prepping them and going over potential scenarios whilst on the way with the intent to be able to drop it the moment they arrive if needed).

a lot of the specialist kit still a way off currently, can see them heading there from St Johns way - Cyan coloured marks the ones to look at

Kind of surprised it seems only the Polar Prince & 2 others there currently (with AIS anyway, suspect naval kit won't be running with AIS on)

It's still taken considerable time before the equipment is on route so I would suggest that the major incident plan is inadequate. Such a plan should exist and have a list of required equipment and sources for it so that necessary arrangements can be made much faster.
 
radio4 pm said appropriate cable has been airlifted to port and could be on site tomorrow - so ships don't seem too slow.

good video - would be interesting to know about relative expansion rate of the two materials

Such a plan shouldn't exist. It will now obviously, but it's purely down to one man who screwed it up. It's never been needed until now.

From what I see is that the whole lot is basically a carbon fibre cylinder with two titanium steel domes bolted/bonded on either end. Everything is then bolted onto the outside. Everything is controlled from inside wirelessly. No wires or anything link from the outside to the inside so if something goes pear shaped then that's it you are locked in without any mechanical way of sorting it out.

I haven't looked into it but I don't think Cameron's sub was built the same way.
