and investigation branch or the faa and america or the marine accident investigation. forthis america or the marine accident investigation. for this there is no precedent for it. so the coastguard admiral was saying basically, the governments are going to have to talk to how we proceed and who takes responsibility. for what should be a forensic investigation to see what went wrong. i want to spend a moment on your friends, for those who didn't know hey mech, what would you say about him? he hey mech, what would you say about him? ., , hey mech, what would you say about him? . , ., ., , hey mech, what would you say about him? ., ., ., , , hey mech, what would you say about him? . , . ., , , , him? he was a lovely guy, very charming. _ him? he was a lovely guy, very charming, gregarious, - him? he was a lovely guy, very charming, gregarious, he's- him? he was a lovely guy, very. charming, gregarious, he's been billed as this british billionaire, i didn't know he was a billionaire, he didn't wear that kind of presence around him —— hey mesh. when i first

met him, we got put together at a dinner with a whole bunch of people, and by the end of that dinner, he and by the end of that dinner, he and i were planning an expedition together with our families to climb kilimanjaro. he saw that we had the same interest, to do something quite extraordinary, and he immediately invited me along to what was already a very well prepared expedition —— hamish. i didn't happen but it was by the by. so he understood the risks, he's done some remarkable things in his life, you know, he used his position in ways that hopefully people will focus on now, and not think of him as somebody who'sjust doing... diving down

and not think of him as somebody who's just doing... diving down to a rackjust for a thrill, you know, it means something to him. he lives and enjoys his life this way, he pushes boundaries, and that's part of life. and we are richer for people like hamish. i don't know the other people, but ph, no longer professionally... ph is paul henri onjuly —— paul henry onjulie? in terms of the contributions he's made —— paul—henry nargeolet. his deep knowledge of the titanic, there's only 1—2 people who have done a dive

only 1—2 people who have done a dive on it,, and he was there for a different reason. that was his living and he understood these risks. he lived these risks every day. and if i wasn't in this chair talking about ph and it was me there, he's the guy i would want responsible for running a search and recovery —— ph. because he could find that many people who had his skills and experiences to do something like this, and we all had no doubt, everybody who knew ph, that if there is any chance these men could escape alive from this incredibly ridiculously difficult predicament, it would've been the calm composure in training of ph. you've spoken so eloquently about both of your friends there, i can't

therefore begin to imagine what the last few days have been like for you, and your friends and family? it's been very difficult and, you know, we have a very small net community, the people who go deep into the ocean on these crafts or with robotic vehicles, and the ultradeep part of the world, we are talking 4000 metres or deeper. and there is something in us that drives us to explore and study, and that is embodied by both these gentlemen. and to have lost two of these fantastic characters is a huge setback to my industry that people will have to think about and reflect

on, and yeah. personally i've lost two friends in the most horrific way. but speaking to the media, i want to have a human face on what these men stood for and what they live their lives doing, and it's more than just this dive on titanic and hopefully that is something that will come out. figs and hopefully that is something that will come out. $5 i and hopefully that is something that will come out-— will come out. as i said before ou've will come out. as i said before you've spoken _ will come out. as i said before you've spoken so _ will come out. as i said before you've spoken so eloquently, l will come out. as i said before i you've spoken so eloquently, and we've really appreciated it, this is beyond imagination because you were absorbing this news just before you came to talk about your friends, we appreciate you coming on and talking to us through that, thank you very much. ., ~ to us through that, thank you very much. . ~ ,, to us through that, thank you very much._ continuing - to us through that, thank you very . much._ continuing reaction much. thank you. continuing reaction as you would — much. thank you. continuing reaction as you would imagine _ much. thank you. continuing reaction as you would imagine to _ much. thank you. continuing reaction as you would imagine to what's - much. thank you. continuing reaction as you would imagine to what's been | as you would imagine to what's been happening, people have been paying tribute online, government figures too, and i want to bring you now a

statement which confirmed the death of all those on board. it reads... we have a tweet now from the uk foreign secretary expressing his condolences...

james cleverly, the uk foreign secretary there. —— dawood. now onto our next guest, he's one of the world's leading experts the titanic and joins us live on the programme now. thank you so much for coming on the programme, we are all around the world just clearly exhorting the macro absorbing this news, what are your thoughts? it’s macro absorbing this news, what are your thoughts?— your thoughts? it's devastating, we were hoping — your thoughts? it's devastating, we were hoping for— your thoughts? it's devastating, we were hoping for a _ your thoughts? it's devastating, we were hoping for a miracle _ your thoughts? it's devastating, we were hoping for a miracle and - were hoping for a miracle and obviously that hasn't transpired. my only glimmer of something positive to say about this is, for those five brave men, their deaths would have been instantaneous and that is better than 100 hours of starving of oxygen. that's the only glimmer of hope, but this shouldn't be allowed to happen again. we need to make

sure that submersibles which carry fee—paying passengers are super and properly tested down to greater depths than they need to experience. let's explore that because we were talking about the unprecedented nature of this, it's not quite clear who will investigate what in this situation where other disasters like this, it's very clear who carries out the investigation. is that a sign that may be something else have been done before a disaster like this? , ., , , , �* , this? obviously with hindsight, it's ve eas this? obviously with hindsight, it's very easy to _ this? obviously with hindsight, it's very easy to say — this? obviously with hindsight, it's very easy to say that. _ this? obviously with hindsight, it's very easy to say that. so _ this? obviously with hindsight, it's very easy to say that. so yes, - this? obviously with hindsight, it's very easy to say that. so yes, it. very easy to say that. so yes, it should have been, but i think it's quite difficult, they were us navy subs including assistance from the french navy, then we've had james cameron in 1997 diving on the rack using russian subs, as well. and what we got is state—sponsored equipment, and what we have here is rather different. 0ceangate was a

commercial enterprise which didn't have state backed funding, and i think the funding wasn't as —— equipment wasn't as good as some of the other equipment was somewhat given the risks and extraordinary depth at which this all takes place, it is a testament to the power of the titanic and the story of the titanic, and people's extraordinary enthusiasm for it still after all these years on?— enthusiasm for it still after all these years on? that's absolutely ri . ht in these years on? that's absolutely right in the _ these years on? that's absolutely right in the people _ these years on? that's absolutely right in the people who _ these years on? that's absolutely right in the people who died - these years on? that's absolutely right in the people who died on i right in the people who died on titanic 111 years ago, those 1500 souls, they almost represent humankind, if you like, and the iceberg really represents the awesome power of nature, the kind of forces that we are witnessing today that just crushed forces that we are witnessing today thatjust crushed that sub in an instant. so really, the titanic tragedy speaks to the human condition. d0

but for fee—paying scientists or military operations, but forfee—paying passengers, they need to be certified to a greater depths then they will be put through. depths then they will be put throu . h. ., ~ depths then they will be put throu~h. ., ,, ,, , . through. tim, thank you very much for our through. tim, thank you very much for your expertise, _ through. tim, thank you very much for your expertise, thanks - through. tim, thank you very much for your expertise, thanks for - for your expertise, thanks for talking to us. just to quickly recap now some of the elements that we have discovered out of the press conference just in the last hour, if you arejoining us, we did learn shortly before the press conference of the depths of the five —— the deaths of the five on board. but after the press conference started, journalists were allowed to ask questions and we did find out some more details as a result of those questions. we learned about five different major pieces of the sub being discovered. we learned more about their location, we knew from this afternoon that actually, they were discovered in the region of the titanic itself, but we got more

detail on that, 1600 feet away. so the question was asked, was this potentially a collision with the wreckage of the titanic or an implosion elsewhere, and the answer seems to be a fairly conclusive that the area in which the wreckage of the area in which the wreckage of the titan sub was found was not an area with titanic wreckage and it hundreds of metres away. so that gives some idea potentially of when this implosion, this catastrophic implosion happened, certainly not at the depths and interacting with the titanic itself. it would appear certainly that the impression given was that actually, this was not a case of a collision because the wreckage was just a few hundred metres away from the site of the

actual titanic. 0ther metres away from the site of the actual titanic. other questions about the timeline — to sub went down on sunday, when did this catastrophic implosion take place? we don't have the exact timings on that, but there was one clue, and that, but there was one clue, and that was there was no sound of the catastrophic implosion after the detection was under way, so they would've picked up that implosion over the last couple days, which means that happened all before the technology and search rescue operation was in place. and the rather grim question was asked, but one very important for families, which is about the recovery of the families, simply that they did not have an answerfor that, families, simply that they did not have an answer for that, but the very nature of catastrophic implosion is like this, one would imagine, it means it's a very difficult issue in question to

answer. those are the new points we've learned after that press conference in the last 45 minutes or so. we can go back to my colleague standing by for us who was live with us around the press conference, and we've had about half an hour or so to try to pick through some of the details of what we learned, what else do we know? i details of what we learned, what else do we know?— details of what we learned, what else do we know? i think it's really interesting — else do we know? i think it's really interesting to note _ else do we know? i think it's really interesting to note that _ else do we know? i think it's really interesting to note that the - interesting to note that the rear admiral here made several points about the fact that this is of course an investigation that's continuing, they must continue to assess the debris to understand what exactly happened. he also said that over 72 hours of searching, they've been having sonar buoys in the water continuously, i hadn't heard any implosion at that point, so it

appears it would happened immediately, perhapsjust appears it would happened immediately, perhaps just after the expedition had begun. he also said the next phase really is about making sure that the families have an understanding of what happened so they can, as he said, get some closure perhaps. but we have dan johnson with us who was at the press conference, and you were also asking some questions and listening in about what the outcomes of all of this is, and what more did you hear from the rear admiral and other officials there? the from the rear admiral and other officials there?— officials there? the coastguard tried to give — officials there? the coastguard tried to give as _ officials there? the coastguard tried to give as much _ officials there? the coastguard tried to give as much detail - officials there? the coastguard tried to give as much detail as| officials there? the coastguard - tried to give as much detail as they could, _ tried to give as much detail as they could, making available notjust the rear admiral could, making available notjust the rearadmiral in charge could, making available notjust the rear admiral in charge but also the other— rear admiral in charge but also the other experts involved in this search— other experts involved in this search and rescue operation. but as the rear— search and rescue operation. but as the rear admiral search and rescue operation. but as the rearadmiral said, it'll take a few days — the rearadmiral said, it'll take a few days to wind down their manpower, and no doubt we will only see a _ manpower, and no doubt we will only see a continuation of effort in that area to _ see a continuation of effort in that area to try— see a continuation of effort in that area to try to piece together exactly— area to try to piece together exactly what did happen here. the picture _ exactly what did happen here. the picture appears to be becoming clear that something did go suddenly wrong

perhaps— that something did go suddenly wrong perhaps very early in that dive on sunday— perhaps very early in that dive on sunday morning, even before those five men _ sunday morning, even before those five men had got to that wreckage of the titanic _ five men had got to that wreckage of the titanic. what went wrong, what was the _ the titanic. what went wrong, what was the problem, and what lessons can he _ was the problem, and what lessons can be learned for the future? because — can be learned for the future? because if this sort of expedition will continue, then no doubt people will continue, then no doubt people will he _ will continue, then no doubt people will be learning lessons to do this more _ will be learning lessons to do this more safely if it's more able to resume — more safely if it's more able to resume this for fee—paying passengers. the rear admiral was clear_ passengers. the rear admiral was clear to _ passengers. the rear admiral was clear to stress that everyone's thoughts — clear to stress that everyone's thoughts were with the families of those _ thoughts were with the families of those five — thoughts were with the families of those five men, who are coming to terms with— those five men, who are coming to terms with this tragic news and get their heads around it. i can't imagine _ their heads around it. i can't imagine the position they are in, but may— imagine the position they are in, but may he — imagine the position they are in, but may be some comfort that there are some _ but may be some comfort that there are some answers and some understanding, and at least something has been found. we could have been_ something has been found. we could have been in the position for days or weeks— have been in the position for days or weeks of— have been in the position for days or weeks of not knowing what happened, at least the picture is starting — happened, at least the picture is starting to emerge. it certainly helps _ starting to emerge. it certainly helps us — starting to emerge. it certainly helps us all learn some of the lessons — helps us all learn some of the lessons of what happened here. he also lessons of what happened here. he: also mentioned this is an incredibly

these types of expeditions in future to be carried out safely.— to be carried out safely. we will be back with you _ to be carried out safely. we will be back with you a _ to be carried out safely. we will be back with you a little _ to be carried out safely. we will be back with you a little bit _ to be carried out safely. we will be back with you a little bit later. - to be carried out safely. we will be back with you a little bit later. i - back with you a little bit later. i want to play you a bit of that press conference we heard just under an hour or so ago. have a listen. but! hour or so ago. have a listen. and our ovi, or — hour or so ago. have a listen. and our ovi, or remote _ hour or so ago. have a listen. fific our 0vi, or remote operated vehicle from the vessel horizon arctic discovered the tail cone of the titan submersible approximately 1600 feet from the bow of the titanic on the sea floor. the our 0vi subsequently found additional debris in consultation with experts from within the unified command, the debris is consistent with a catastrophic loss of the pressure change or —— rov.

on behalf of the united states coastguard and the entire unified command i offer my deepest condolences to the families. i can only imagine what this has been like for them, and i hope that this discovery provides some solace during this difficult time. so that was from some of the press conference within the last hour, clearly a difficult message to deliver, something that the families would have been notified of a little ahead of time, but still a difficult message to convey, and we have been receiving tributes and messages from others involved. and we can see now the latest message from the explorers club.

tributes there to the five men who have been lost. this is bbc news. hello there. it's going to be heating up over the next few days and turning much more humid as well. now, today, we've had a few heavy and thundery showers across england and wales. those will fade away. if we look out in the atlantic,

though, this cloud is going to be coming in, and that will bring with it some outbreaks of rain eventually later in the night across northern ireland, heading over the irish sea and affecting western scotland by the morning. and ahead of that, it's going to be quite a warm night as it becomes dry in other areas, but there are some warmer and more humid nights to come, more uncomfortable nights to come, over the weekend. as we head into friday, though, this rain in northern ireland replaced by some heavy showers, patchy rain runs across scotland, affects the north—west of england and across wales. but towards the south—east, many areas, i think, here will be dry. this is where we'll see the best of the sunshine developing and it's going to be very warm again. temperatures easily into the mid 20s. cooler further north and west, where we've got the cloud and chance of some rain. a bit misty over the hills as well. some of that cloud will be pushing its way down into trent bridge for day two of the women's ashes. but it should stay dry and there will be a bit of sunshine at times — maybe not quite as warm as it was today, mind you.

by the time we get to saturday, most of the rain will have gone. we're left with a lot of cloud. there'll be a few showers, mainly running northwards across scotland. we should see the cloud thinning and breaking. more sunshine coming through. that's going to give the temperatures a boost as well. getting into the mid 20s for scotland and northern ireland, could be close to 30 degrees in the south—east of england. not only are temperatures rising, it's getting more humid. it could be a little uncomfortable if you're going to be sleeping in a tent over the next few nights, but it should be dry until sunday, i think, at glastonbury, where we could see some showers in the afternoon. but that heat and humidity is building ahead of some weather fronts that will bring some rain, that humid air coming in from continental europe. but this weather front here is going to change things during the second half of the weekend, in time for next week. we're looking at heavy, thundery rain for northern ireland. that'll push its way into western scotland, across wales, into western parts of england. eastern areas still dry until later in the day. this is where it's still very warm, hot and humid as well, but to the west, things will be turning cooler and fresher as the rain comes in, and particularly after the rain. that rain will have swept through overnight.

and then we're into something more unsettled for next week. showers never too far away and things are going to be a little cooler.

hello, i'm lewis vaughanjones. you're watching the context on bbc news. the debris is consistent with the catastrophic loss of the pressure chamber.

upon this determination we immediately notified the families.
