p.h. nargeolet, a legendary expert on "the titanic." there is comfort in knowing he was in the place he loved. ceo and founder of oceangate expeditions, stockton rush, who saw himself as a maverick, talking about how the "titan" defied industry standards. >> i'd like to be remembered as an innovator. i think it was general macarthur said, you're remembered for the rules you break. and i've broken some rules to make this. i think i've broken them with logic and good engineering behind me. the carbon fiber titanium. there's a rule you don't do that, well, i did. >> reporter: we're learning more about concerns over using carbon finer and titanium to make the experimental sub, an untested material at extreme depths over time. tonight with the world watching, yet another tragedy. 111 years after the "titanic's" doomed voyage, five souls captivated by its story now resting in those same waters. >> byron: our thanks to gio. now to two people with a unique and intimate knowledge of "the titanic." robert ballard, who discovered the ship's wrecka

p.h. 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 thi

p.h. nargeolet, the veteran deep sea explorer who also perished in the "titan."o the "titanic" more than just about anyone. how many times have you been? >> with the last dive, 37 times. >> you've been to the "titanic" 37 times? >> yes. i was in charge of one, two, three, four, five -- five subs. >> how different is the "titan" from those other subs? >> completely different. most of them, you have a sphere. >> was there never a point when you wondered about the safety of the sub at that depth? >> no. two, three years ago, i had a phone call with stockton. and he explained to me that he was doing a lot of tests. he showed me some of the ways they were building the stuff. i say, okay, that's fine, that's fine, i have no problem diving the sub. >> reporter: i was also impressed by the sub's seven redundant systems for returning to the surface. so you have a backup of a backup of a backup of a backup of a backup? >> correct. >> reporter: finally, the crew seems to foster a culture of safety. there were checklists, inspections before and after every dive, and a "three

p.h. nargeolet, the french naval captain. i had dinner with him six weeks ago.t really didn't have the experience to safely operate in that, and that makes me heartsick along with the way that thing was constructed. >> rachel, how important is it for the debris that has now been spotted on the bottom to be recovered, to be analyzed to figure out what went wrong and to learn from this cuatastrophe? >> to be equally as blunt from captain mclaren, i don't think there's a lot we could learn from this because this was a company defying much as we already know about submersible design like what we know already about carbon fiber and titanium. >> captain, there has been some criticism from james cameron, a person whose name is perhaps more closely tied to the titanic than anyone because of the movie that he directed. and he told abc news, quote, i'm struck by the similarity of the titanic disaster itself where the captain was repeatedly warned about ice ahead of his ship and yet steamed it full speed into an ice field on a moonless night, and many people died as a resu

p.h. nargeolet are also said to be stuck on back in 2000 an underwater current drove his sub right into the propeller of the ship. >> it's pretty scary. i'm very aware of what these poor souls on board the ship the titan are experiencing. i'm just heartbroken about it. >> so much concern for that crew on board. gio benitez joining us now from halifax. geo, we know that the ship has that deepwater camera under the water searching for signs of the titan. but planes and boats still combing the surface as well, right? >> reporter: that's right, whit. the titan is actually bolted shut from the outside. that's part of the concern here. crews are still searching above water and they are seeing if they just suddenly rose up and ended up floating in the water and they're just waiting for rescue. that is what they are hoping for. but no doubt about it, timing is still critical because that oxygen on board is so limited. >> just over 30 hours left. gio, thank you. >>> now to hunter biden reaching a settlement with the justice department. it comes after a wide-ranging five-year investigation led by a t

p.h. nargeolet is on board, and they say his first instinct would be to conserve oxygen and have everybody sleeping or very, very calm or as calm as possible. if they are alive it is dark and cold and they are facing enormous odds, but there is hope among the search and rescuers that this is a search and rescue, and they will not stop until they are definitively figuring out what has happened to the titan. back to you. >> is there any indication of how long the rov can stay on the ocean floor looking for this vessel? >> it is a remotely operated vehicle, so many hours it can be down there, and presumably what they will do is to get down to this area, it is not clear how close it is to the "titanic" wreck site, but there is the possibility that the titan was tied up in the "titanic" wreckage as well which may complicate things, but they will establish a grid to come, and a second subcoming down for the first sub and do that and the same thing from the air with the sea 130s and the poe sidon aircraft and one searches and comes back and another comes back, and they have searched massive areas

p.h. nargeolet is than and tom, we have talked about ph's expertise and the knowledge and the years in the water, and how important and critical that could be to their survival if they are alive down there. >> that's right. ph has more submersible dives than just about anybody on the planet, and it is in a wide range of submersible, and he has been in a number of programs, and the experience is incredible. it is going to be far more ranging than anybody else down there at the point. >> tom, thank you for coming back in to speak with me today, and let's hope for some good news today. and we will check back in with you. >> absolutely, kate. thank you. >> sara. >> great conversation, kate. the missing submersible is cramped, and likely filled up with carbon dioxide and what the conditions would be inside of the sub likely four days after losing communication, and diplomacy on display. >> narendra modi arriving at the white house and how the united states and india might strengthen ties after fraught tensions with china. >>> and now, the ntsb is trying to find out what caused the damage of the

p.h. nargeolet to the mother ship, the polar prince. >> the other thing that i heard was that p.h. contacted the surface ship and said there was a problem. we're dropping weights and surfacing immediately. now, i can't verify that, but that to me meant something really happened very quickly. >> reporter: most of the ships participating in the massive search and rescue mission now returning to home port. some still on the scene, mapping the debris field, looking for clues in the shadow of the titanic, trying to understand with certainty what caused this latest tragedy in this isolated corner of the atlantic. so what they're doing now is mapping that debris field, trying to get a sense of the dynamic of that implosion and to drill down basically into what exactly happened. was it the carbon fiber hull? was it the titanium? was it the window? was it a combination of some or all of those things? they may also want to bring up pieces of the titan, but that will be much more difficult. back to you. >>. >>> still ahead. hot and muggy. we'll get the weather forecast for the first weekend o

p.h. nargeolet, the legendary explorer from france, and obviously, the ceo, stockton, who was there on theratch and knows how it works. they held on to hope because of the banging noises. the so-called banging. they didn't know what they were. they determined they were inconclusive. they were hanging on to hope as they got each and every piece of information from u.s. officials. right now, they know what exactly has happened as the rest of us wait for an update -- >> paula, i have to cut you off. we have news directly from the white house right now. president biden and prime minister modi of india are holding a joint press conference. let's listen in. >> 200 american-made aircraft this year. well this visit, indian firms are announcing more than $2 billion, more than $2 billion in new investments in manufacturing, solar, in colorado, steel, ohio, and optic fiber in south carolina, and much more. further proof that america's manufacturing is back. we're expanding educational exchanges for our students, building on the record, 125,000 student visas for indians to study in the united states w

p.h. nargeolet onboard. we are hoping alongside you they are all okay and still alive.an you speak to what role the buoys dropped, the ships and aircraft can all play together? >> sure. yeah. the aircraft, so you can fly overhead looking down at the surface to spot things, use radar also to spot things at the surface. once you get below the sea level though, the water level, you're in a world of sound. not things you can see easily, but, you know, sound travels a long way beneath the water. you can't hear that from a plane overhead, so they drop the torpedo-like sonar buoys from the plane into the water. they have the acoustic listening. so they are listening to the underwater world and they take the sounds that they hear, very sensitive, and send them back to the aircraft for analysis. it's the only way really you can hear what's going on in the deep from a plane overhead. now, i don't know, typically these are made to find submarines and submarines don't go anywhere near -- navy submarines don't go anywhere near 3,800 meters depth. so i am not sure if the buoys can he

p.h. nargeolet is on that craft.e i have spoken to here that know him, that know his abilities, say that he would have kept people calm in there, kept them breathing very shallowly so they could preserve as much oxygen as possible. this is still very much a search and rescue mission and searches are going to treat it as though they are alive. important that they got an rov down to the bottom and on the bed of the ocean in that area, but they still don't know exactly where the titan submersible is. there is no beacon. no clear indication of where it is. those banging noises you mentioned, they were described as banging noises by some. coast guard saying they might be banging, they might be something else. they are not sure what they are, but it's their best clue right now. it is a sliver, a tiny sliver of hope and they are grabbing on to that, moving to the area where they heard that sound in the hopes of finding them and being able to rescue them. if they can locate that submersible, then they'd have to get the salva

p.h. nargeolet has been doing it for many years. he wouldn't be in that submersible unless he thought it was well equipped. anything can go wrong. >> harris: i appreciate that. i still hear optimism from you and i share that. i pray. but i also understand the limits of what you are talking about, too. and i hear that in your voice, that caution. thank you for being with me today. i appreciate it and appreciate you sharing your conversation that you had with the ceo. >> my hopes and prayers are with those five people and their families and all those amazing people out there working right now. i hope -- we need a miracle. >> harris: amen. thank you very much. appreciate it. chaos on the floor after the house censured a member for just the 25th time in history. >> on this vote the yays are 213 and the nays are 209 with six answering present. the resolution adopted without objection, the motion to consider is to be laid on the table. house will be in order. >> harris: republicans call it accountability for congressman adam schiff's lies

p.h. 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

p.h. nargeolet was sitting here with me like he normally would be, this is what he would say to do, let'st sit down together in a small room, figure out what needs to be done and let's make it happen, let's do it. >> tom, what do you think p.h. would be saying right now? >> it would be exactly that. he is very calm, collected, expert in his field and, you know, we would have approached this in a very scientific manner, very straightforward manner and just get the fastest reaction out there that we could have. i've spent the last two days trying to get an effort out there, it's on its weiwei now and i know that p.h. would have done the same thing for anybody else out there, whether he knew them or not. the community would have drawn together just like you've seen it over the last couple days and we would do anything in our power to get out there. never questioning costs, never questioning time, you know, just do it. drop everything. >> tom, talk to me about the effort and what you're trying to get out there and what you've seen that's been deployed so far. talk to me about the scope and sc

p.h. nargeolet was a 77-year-old former commander of the french navy. he is also a deep sea search expert who has completed at least 35 dives to the wreck of the titanic. he's considered one of the foremost experts on the titanic. he also is the director of underwater research at rms titanic which has the exclusive rights to salvage artifacts from the wreck. nargeolet was also part of the effort to find air france flight 447. which went down over the atlantic ocean. you're talking about a moment ago, shahzada dawood, the father, he was 48 years old, a pakistani british businessman and philanthropist. his daughter said that he was obsessed with the titanic and took his 19-year-old soon suleman with him. he had just graduated, i'm sorry, finished his first year of business school. and also stockton rush, he's the ceo of this whole endeavor, of oceangate expeditions. he was 61 years old. and aerospace engineer with a well documented love of deep sea exploration. he designed this submersible, and as we've seen in the past few days of coverage, it was jury r

p.h. nargeolet. they heard noises that could not be explained thought perhaps there was a chance.nds to indicate that what they are being told by the u.s. coast guard, this debris who been found. there is still a lot more to do here in terms of to find this submersible and understand exactly what happened. again, we continue to reach out to canadian officials and i will say the transportation safety board here in canada would be in charge of any investigation and at the ready and again deployed so many assets there in terms of recovery. they will be able hopefully to give those families what they need, which is information and peace of mind. >> it has been an extraordinary effort, all hands on deck to try to give these families information as they deal with such a difficult process, first learning that their loved ones are missing. now hearing this news. paula, please, stand by for us. we're, of course, going to stay on top of this story. again, breaking flus. there is confirmation debris located near the wreckage site of the "titanic" confirmed to be from the exterior hull of the

p.h. nargeolet and i go way back. you couldn't ask for a nicer guy, more competent guy. in france, they call him mr. "titanic." he's the kind of person you would want to have in that situation because he's -- he's got a lot of wisdom, and knows his way around submarines and knows his way around "titanic." so, i can't imagine anyone better to be in a -- i wouldn't wish that on anybody -- but if i were in that situation, he's the person i would want to be stuck with, yeah. >> david, these are such small crafts, right? and the pressurization issue is so important. i'm just wondering what are your thoughts, you know, sunday to now wednesday and also, you know, do you -- do you have hope? >> because of the banging, i have a lot more hope than i had two days ago. because there was maybe two days ago this report that there was an implosion heard by underwater -- said a seismograph that was heard around the same time as the last communication with the sub and the sub was in midwater. that made sense to me that made the sub imploded and that's why there has been no more communica

p.h. nargeolet. what was he like?xtraordinary career. >> oh, you know, he was -- he's the true explorer, undersea expert. you know, i had dinner with him in new york city just six weeks ago, and i asked him about he's still diving titanic. i thought he was using the french -- and he told me he made 47 dives on titanic now. when he told me he was working with oceangate, i was shocked. and unfortunately was sitting there with eight other people. i didn't get the chance because he was a few people down from me. p.h., what the hell are you doing? well, thinking about it now, you know, there's some people that -- particularly archaeologists. they get fixed on certain sites, particularly egyptologists, for instance. and they go back again and again and again. and he had a passion for titanic. it was the locust of everything for him. i think he could return, just keep going forever. and this particular vessel is the only thing available. i'd like to just jump back to the pressure hull again. it's really interesting to me tha

p.h. nargeolet, and i want your reaction to the ceo, stockton rush, said in the past about innovation and breaking rules. >> i'd like to be remembered as an innovator. i think it was general mcarthur said you're remembered for the rules you break. i've broken some rules to make this. i think i've broken them with logic and good engineering behind me. >> specifically combining carbon fiber and titanium on a vessel like this that hasn't been done. what's your reaction knowing all of your experience? >> well, let us understand i'm a physician scientist not an engineer. i don't want to go near that subject, but i want to say one thing and that is that for all of us who work in the deep ocean, there are two fundamental rules and the first rule is take care of each other and the second is take care of each other. as your reporting has told us for the past four days this international search team has done everything possible to try to find the vehicle and rescue the occupants, and they've moved heaven and earth to make this possible. they have honored that code and so i think no matter what happ

p.h. nargeolet, who you've been referring to, who is a remarkable man, took the control of it and really touredhe talking about what -- >> everything. i mean, we spent all week with him. so we got to know him very well. but he -- you know, for five hours we got all of his knowledge about the titanic. >> yeah. >> and 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 1/2-hour ride up. >> well, i'm glad you were ok on that. and i appreciate you talking to us tonight. >> my pleasure. >> i'm sorry it's under these circumstances. colin taylor, thank you. >> thank you. >> up next the promises oceangate expeditions made of adventure and safety before its launch. we'll be right back. to debt in e and, no matter how much i paid, it followed me everywhere. between the high interest, the fees...i felt trapped. debt! debt! debt! debt! so i broke up with my credit card debt and consolidated it into a low-rate personal loan from sofi. i finally feel like a grown-up [crowd cheers] ditch credit card fees a

if there's anyone you want to be down there this team, like p.h., paul-henry nargeolet, in subs for 60c, and stockton, his vision of ocean exploration was pushing, you know, was pushing this effort forward and even the mission specialist, the tourists, these are people that were experienced explorers that knew what they were doing, would have been calm, collected, everything they could. so an amazing -- it's not an average set of people off the street. these are real people that were changing the world. >> ainsley: and you know, when you talk to, at least stockton, i've heard him in interviews and he was interviewed by cbs and said it's all risky but in order to learn more and as an explorer part of my job and what i enjoy doing. he said at some point safety is pure waste, i think i can do it just as safely by breaking the rules. was that his personality, and should that cause concern for the company? he's running this company but also putting lives at risk, too. >> well, i mean, that's taken a little out of context. certainly safety was the number one priority for these guys. when we

p.h. is with them. nargeoletembers of the team and you couldn't have a better person with you in a situation like this than p.h. who has made 35 dives to the titanic, who is calm under pressure. the best kind of leadership will be coming from p.h. he will be calm, quiet and doing all of the right things to conserve energy and to conserve oxygen and to conserve psychological, emotional energy, as well. >> because that expends more oxygen, as well if you start to hyperventilate or start to freak out. can you talk to me about how significant the sound that sonar has picked up. there has been, every half an hour for about four hours a banging sound is how it has been described. is that something that you're trained to do to make sounds so that someone might find you or does that tell you that this is definitely human activity or something else? >> well, as your previous guest mentioned, it's an indication possibly of -- of human activity that is coordinated and again, this is the kind of thing that we would hope -- w
