paul-henri nargeolet is a french deep-sea explorer . he has been down to the titanic debris field 35 times. in a now haunting interview, nargeolet spoke about what would happen if his submersible were to get stuck at the titanic wreckage site . >> if you are in the sub and nothing is running anymore, making some heat. it is very cold. after a while, you will die because of the cold, which is not a bad way to die because you fall asleep. you don't suffer. we know that. we know things could happen. it never comes to our head. >> sobering words from nargeolet. it appears perhaps that these five men did not suffer, depending on the nature of this implosion. in a moment, i will speak to paul-henri nargeolet 's stepson. first, i want to go to jason carol who is live in boston. what is the latest you are hearing from officials tonight about what happened and why and when? >> reporter: the u.s. coast guard says that those remotely operated vehicles are going to continue their search, their map of the ocean floor where the debris was found to se

nargeolet. >> neil: mr. titanic as well. he was a great expert. he had taken a number of trips prior. i'm just curious what you think this means now for other titanic enthusiasts that many of whom were willing and quite happy to pay up to $250,000 for the chance to see that wreckage for themselves i imagine this will stall for the time being, maybe forever. what do you think? >> i don't think it will stop forever. i think the exploration of the depths of the abyss is just beginning. up till this time, it's been government-funded vehicles that have gone deep. set records. you have some people that take actual tourists down 100 feet. i heard someone talking about how they do that. i dove deeper than 150, 200 feet wearing nobody but a swimsuit and scuba tank. i'm not impressed. very few people -- in fact, many more people have been to outer space than have been to the depths of the ocean and seen the titanic. many more people. so we're talking about the last great frontier on earth. stockton used the titanic to bring people in because he was a entrep

nargeolet had dedicated his life to be a pioneer to deep sea floor exploration. and the leader of the wreckage of the "titanic" is a close friend of ph nargeolet, and tom, when i left our conversation yesterday, i have to admit that i was slightly hopeful from kind of the back and forth of what we have been discussing and hearing from u.s. coast guard from the search and the week, and then after our conversation on the show yesterday, you heard the news a few hours afterward, and what has been going through your mind since? >> well, kate, those of us who really understand the issues behind this and the indicators that first came up sunday during the disappearance suspected that this is the most likely scenario. so we put that into the back our mind, but we had to pursue the possibilities that other things had happened. we couldn't rile out that there were other scenarios. but it was haunting us in the back of our mind. it wasn't a total surprise that's what was found yesterday. very disappointing of course, and a great loss. >> absolutely. the coast guard saying

nargeolet. so still processing this. >> paul-henry nargeolet was a friend of yours. he died doing what he love. in all appearances, he died in an instant. what are your thoughts on that? >> yeah, p.h. has been involved in the titanic expeditions for many years. the first time i worked with him was in 1998 on expedition 98. that's how we met and became friends. he monitored me along the way over the years. like you said, he's according to what they're saying, he's lost at the titanic wreck site. you know, doing what he loved doing, exploring and adventuring. >> the coast guard was not optimistic about recovering the remains. is it fitting that your friend is down there with a magnificent tombstone now? >> i wouldn't know what the recovery effort would be and what that would involve. but if that's the case, yes, he's had a very memorialized site. and arresting place that is -- hopefully will be well-respected going forward. >> you have been down to the wreckage of the titanic. you took arrest at the time. has your perspective changed? >> no. when i dove 20 years ago th

hamish harding, suleman dawood and shazshahzada, and paul-henr nargeolet and stockton rush. about the wreckage seen on the floor that gives them confidence those onboard did not survive? or are they surmising from seeing some pieces of the wreckage there that, therefore, the capsule did fnot survive those depths? >> reporter: they are surmising that, because of the wreckage they have found that the ca cape itself would not have survived. must have been a catastrophic failure at the moment of the event, and that then led to the debris field which has, you know -- the -- the depths and the, and the pressure put on capsuled like that is stunning when you start to talk to these people about just how difficult it is to do this and how technical it is. and -- so i, i think once they were able to confirm that those parts were, in fact, from the "titan" sub, and even if they haven't found the capsule, because of the nature of the parts that they have found they realize that -- that the rest of the sub is gone and lost. jim? >> miguel, thanks so much for sharing that important and th

. >> the banging sounds are interesting because knowing nargeolet and his experience with submersiblesund with submarines this is exactly how he would try to indicate that they were still alive and try to communicate with the surface. you would do some banging and do it on a regular schedule so it was distinguishable from the background noises in the ocean all of the time. >> cnn's miguel marquez is in st. john's in newfoundland which is the closest land mass. what are you seeing this morning? >> well, we're seeing -- we saw a lot of activity here overnight and early this morning. coast guard ship, a third canadian coast guard ship now headed out that way. it takes, 10, 18 hours to get to the site where they're searching. the horizon arctic left earlier this morning and this is after three u.s. military planes, c-17s and very big cargo planes flew into st. john's airports and that gear was put on to the horiz horizon arctic and that is on its way right now. with regard to the banging, they heard it over a four-hour period every half hour or so and they put sonar buoys into the ocean. t

now believe that our ceo stockton rush, shahzada dawood, his son, hamish harding and paul-henry nargeoletare sadly lost. a deep passion for exploring and protect the world's oceans. our hearts are with these five souls and every member of their family during the tragic time. we grieve the loss of life and joy they brought to everyone they knew. so i guess what we are going to hear at 3:00 from the coast guard, tom, is that the debris field is that of the titan, that it's in pieces, that would suggest a catastrophic implotion back on sunday morning as they were descending so the titanic. your thought as we get this news. >> well, it's -- it's a gut punch, it's probably what was in the back of minds of most experts but we don't want to admit it or give into that, never give up hope. there is still a small hope that the hull is intact, but it's highly unlikely. and the equipment they do have on board, the rov they have there is capable of bringing this up. it's not something they will do in the next few hours, but it sounds like the worst has happened. >> sandra: i'll just finish that statem

it was obviously couldn't verse verse y'all but people like ph nargeolet was on that craft and believedn it and many others did as well. they want to understand what exactly failed with this craft and try not to repeat that in the future. >> absolutely. miguel, thank you so much for your reporting from there. sara? >> with me now is former abc news science editor michael guillen, he is a scientist, journalist and author, but for this story most importantly he was the first television correspondent to report from the titanic, which means he had to get into a submersible to get there and it didn't go well. good morning to you. can you tell me what happened when you visited the titanic for the first time? >> yes, good morning, sara. in september of 2000 we left nova scotia, halifax, went out to the point in the north atlantic where the titanic went down and then we dove. the dive went very smoothly, took us about two and a half hours to get down there, corkscrew down. we got to the bow first and we had a silent prayer for the people who had lost their lives down there and i think, sara, th

ph nargeolet who you've been referring, to a remarkable, man, took control of.l of the titanic. >> was he talking about what happened? i >> mean, we spent all week with him. we got to know him very well. he, you know, for five hours, we got all of his knowledge about the titanic. >> it was incredible. we did try and make a run for the stern. which is about 600 meters, away we couldn't find it. and then we went for the surface, another 2 and a half from our ride up. >> i'm glad you're okay on, that i'm sure you talk to us tonight. >> my pleasure. under the circumstances, collin taylor, thank you. up next, the oceangate expeditions made of adventure and safety before, it launch. we'll be right back. it my mental health was much better, but i struggled with uncontrollable movements called td, tardive dyskinesia. td can be caused by some mental health meds. and it's unlikely to improve without treatment. i felt like my movements were in the spotlight. ingrezza is a prescription medicine to treat adults with td movements. ingrezza is different. it's the simple, once-

common practice within naval -- and you do have on board the french navy person, but paul-henri nargeolet, and he would know that. >> it's interesting, i had not consider that, the idea that banging on the top and a half of each hour, which is not a natural occurring cycle in nature, it would indicate that there is an idea, that there is a human behind that, or an intention behind that banging that is not just some sort of ocean noise that be occurring every 30 minutes. >> no, exactly, imagine how unlikely it would be that nature, precisely on the half hour, it would do that banging noise. it's pretty much inconceivable. therefore, i think we have a very high degree of confidence that those banging noises come from the submersible. that was actually the good news island to day, that they are there, they're most likely alive, and we have a fighting chance. so, that's good news. >> so, if the people on board have less than a days worth of oxygen left, are there things they can do to try to stretch that supply out? i mean, obviously, you're trying to remain calm, i got sleeping, in order to

. >> reporter: friends of french explorer paul-henri nargeolet say he was a consummate professional and generous. >> i think we would like to be remembered as somebody who continued the story of "titanic." >> reporter: oceangate, the company that operates the "titan," released a statement saying, "our hearts are with these five souls and every member of their families during this tragic time." for years, industry experts have criticized the company, which charges $250,000 for its expeditions to the "titanic" site, over safety concerns. >> they cut corners. they usesed unproven e experime technology on a sub that took passengers. and to me that's inexcusable. >> reporter: an investigation is under way to understand what happened and the cause of the implosion. now it's not really clear right now which agency or even country will lead the investigation long term. the coast guard has noted that this part in particular is pretty complex because of where this happened -- in remote waters involving people from many different countries. and those banging sounds that had been picked up tuesday

her son, but also the other men that perished at sea, stockton rush, hamish harding and paul—henry nargeolete it was great to have different faiths altogether in that way and i think what was really important to christine that was to pay tribute to her husband and son in the way that she felt was right, and we did not ask her questions that made her feel uncomfortable. this not ask her questions that made herfeel uncomfortable. this is her feel uncomfortable. this is a herfeel uncomfortable. this is a grieving woman who, as you mentioned there, lost her husband and son, and incredibly painful moment for her, but she wanted to share how she felt with the bbc. the sentence, "we lost comm." i think that would be a sentence i will never want to hear in my life again. like, lost comm, as in, we lost communication. were you aboard the vessel, were you here? yes, i was aboard the vessel, i was on the ship. i think i lost i hope when we passed the 96—hours mark. that's when i lost hope. and that's when i sent a message to my family onshore. i said, "i'm preparing for the worst." that's when i lost h
