Yes we know they're billionaires
We can discuss things that are horrifying and ghoulish, thanks for your opinion.
Migrant boats are sad too

As you were 😁

Lochridge said the safety cutting was terrible and they refused to put it through mariners safety tests arguing that because it's innovative that it's couldn't be fairly tested.
The acrylic window foe example.

With regard to the Magellan being blocked - I am sure that there will have been a valid reason, either that or the "block" has ben misinterpreted by journalists. If not, then the US authorities have a lot to answer for - governments as well as individuals like to hold pissing-up-the-wall contests and it is always the innocent who suffer when they do.

The Magellan is obviously a valid rescue craft, but I would think they've had to be very careful who they have allowed into the area - everyone with a half-arsed company has a chance to want to be in on this, and they don't want a load of idiots rolling up getting in the way like Paul Gascoigne arriving with a curry and a few cans to talk Raoul Moat into giving himself up.

Personally I'm not going to go USA-bashing until we find out exactly what has transpired.

@icelollycraving

Mumsnet is the bee Google and has always been outstanding on all these sorts of issues ie drawing in one place so navy thoughts, experience, expertise etc.

Thanks

GPS doesn't work underwater (unless you are extremely close to the surface).

I don't know if it had GPS fitted - if so it would have been back up to the satcomms (which work at a greater depth - to about 200m)

12,000 metres I mean **

Why on earth wasn't it fitted with a GPS system?

That has a very simple answer: GPS doesn't work underwater, much less under 4km worth of the stuff.

I don't think we will be given that info in real time.

Hopefully they'll have an eleventh hour stroke of luck down there.

Sorry if this has already been asked or if it’s in the wrong place. Was talking about it to DH earlier and got onto the subject of The Big Piece which we saw in the Las Vegas exhibition. He said, well if it’s almost impossible to raise the submersible (if it was located) how did they pull up a 20 tonne chunk of hull?

GPS doesn’t work under water. Nor does radar.

On the BBC documentary (the travel show- take me to titanic) they encounter issues underwater, it's interesting to see their reactions and that this seems to have happened plenty of times previously. It does seem a bit bigger on video too, not huge obviously but a little bigger.

I've carefully not watched any videos listened to recordings. I get too emotional, so have avoided it. I've just been overcome with a wave of tearfulness about something only very tenuously connected. It's odd how the brain works.

Magellan was not blocked due to financial reasons. They were initially told to prepare to come out, then delayed, then ‘out of office’ replies from pivotal US officials for both Magellan and British govt, and then told to stand down once US informed UK that they wouldn’t authorise entry. Magellan is the leading voice on this area, and their expertise would have been valuable to have given it was available and able to arrive at a workable time period relative to those ships just now arriving.

@RoseAndRose - I wasn't aware GPS doesn't work underwater, thanks for the info

Does anyone know if there's any hope from the hypothermia angle? The whole thing about cooled bodies slowing down and having a longer window for revival?

Do they know what depth it was when communication was lost? If it was only 1000m then it was nowhere near the Titanic and the debris?

Thank you for this thread.

Just a reminder...

@OooohAhhhh As GPS does not work in deep water - even nuclear submarines have to come to quite near the surface and put up a comms mast to get a GPS signal!

If the electrics failed, was there a back-up?

Trying to remain optimistic.

The window has been down to that depth at least 5 times

Now, could it have degraded from the repeated extreme pressure and depressurization? Possibly, but then so could any other part. Metals develop microfractures. I don't know so much about carbon fibre, but it probably does similar.

I've also just watched the BBC documentary that was made a while ago, gives a bit of an insight into the company and why people choose to go down there.

choose to go down there. The documentary can be found here (iPlayer)

It's about the actual company and has lots on the Titan.

It was 1:45 into an apporx 2 hour trip down. So they were close to, if not at, full depth when comms were lost

Copy/paste fail sorry but the link still works.

@TinaYouFatLard - with great difficulty, is the answer. Lots of videos about it such as this one

Also, it's a "better" shape to bring up - (relatively) easy to tie cables round, quite stable etc.
