safety by being there. and hammish i think just very much wanted to see the titanic and they were the only operation offering people to go down. >> i know this is a tragedy for you having this happen to your industry and losing friends. you obviously have your own submersibles. but it doesn't change who you are. as you said who you are since the day your mom got you a bike that you wanted to go everywhere. where do you still want to go next and dream of going? >> there's still other deep ocean trenches i've not visited so i would like to visit those as well and there's also going into space. i've done it once and it was extraordinary. >> it's amazing to sit with someone like you and just imagine how you see the world. thank you so much. i appreciate it. >> thank you for your time. >> and thank you to all of you for being with us. ac 360 starts now.

>> good evening from st. john's newfoundland. a lot has occurred. right behind me two ships involved in the search for the titan, the canadian coast guard vessel and another ship have just now returned here to port. this is them coming in just moments ago. the canadian coast guard ship anne harvey is expected here within the next hour or so and titan's support ship the polar prince is due back here overnight or early morning. polar prince left here as you know a week ago just today a week ago today traveling the more than 400 miles to the site of the at a tannic. it was to be titan's first trip of the season down to titanic.

>> it blew apart and imploded.

two different debris fields and they're hoping through pictures to understand and scanning that to understand exactly what the dynamic of that was and if they can learn anything from it. >> also just the number of warnings that we are now hearing about, about the sub. and i think we're going to hear more about the concerns raised and whether or not modifications were made or changes were made. >> so the 2018 letter, the sub that letter was written about was a different sub that went down in the titan that we know now. it is what is still -- >> in the 2019 email as well that was also a different sub because he made modifications. >> so we're still learning more. it is what is not clear because there are a lot of concerns about the design and materials. what is not clear is what oceangate did.

many people believed it was safe and sound but we don't know everything done to meet the standards in this very serious and technical community. >> and not just the initial testing on the design concept but also just check up testing after dives and with each season how much, how rigorous was that if at all. >> i think that's the real problem here because carbon fiber and other materials they don't know as much about them. >> there's certain things that this to be buttoned down so the pressure vessel is not mcgivered at all.

>> stockton rush defending his design of the titan touting impressive partnerships over and over again. we partnered with aero-spaerosp experts at the university of the washington. cnn has learned boeing and the university of washington are denying partnering on titan. in a statement uw tells cnn the school of oceanography testing tanks were used by oceangate but no uw eh researchers were involved and personnel did not provide any verification or validation of any oceangate equipment as a result of those tests. and the school's applied physics lab told cnn its staff only worked with oceangate on a different shallow diving submersible. boeing firmly told cnn the company was not a partner on the

titan and did not design or build it declining to comment further. nasa whose collaboration rush raised frequently told cnn it consulted on materials and manufacturing processes for the submersible but did not conduct testing and manufacturing or any approvals. titan was not certified by an independent firm and in 2019 the company put up a blog post defending that decision. but two months later after a test dive in the bahamas, oceangate publicly raised the name of one of those certification companies saying the dive was validated by a representative from lloyds register. in a statement, a spokesperson for lloyds tells me it declined to request to certify titan after observing the dive and did not go on to class the installation. the spokes person would not eh ablate. >> the sub many reap with new materials is extremely

challenging and when i mean extremely challenging aye not trying to be hyperbollic. >> warning that an experimental approach to titan could have serious consequences. >> do you feel it's validated the concerns raised in 2018. >> everybody is saying the same thing. anybody that has gray hair and you're interviewing is going to tell thank you same thing. this was preventible. >> based on your reporting were the passengers on titanic pay plead guilty money for this were they misled about the safety of the vessel? did they have this information? because the verbiage used partnering with nasa and boeing and certainly leaving the impress those organizations were deeply involved. >> anderson they certainly did not have all of this information. whether or not they were misled is for others to decide. and in fact all these companies

and institutions had some connection with oceangate but the ones we spoke with are saying the relationship was different than how oceangate was characterizing it and we have reached out to oceangate for these claims but the company just has not commented. >> appreciate the reporting. thank you. we mentioned carl stanley and his 2019 email warning to stockton rush at the top of the program. i spoke to mr. stanley just before air. >> carl, if you can describe for us what it was like when you were on titan and the noises that you heard when you went down. >> yes. so stockton warned us ahead of time to prepare us. he told us that when he was down there that the submarine made many loud noises and that this was to be expected and it was not anywhere close to

catastrophic. he also tested models at this point and he had -- he knew where the models fell so i didn't feel our life was really in grave danger at that point. i feel the real failure came with cracking over time and also with the joint and water getting in there. and another thing that happened was he can trolly sis because even carbon fiber is not a metal but sometimes it behaves like a water so the salt water in between there and the titanium flange over time would have caused even more delam nation with the carbon fiber. unfortunately i doubt there's enough pieces. >> you don't think it's -- you don't think it's a coincidence that this implosion happened on the first dive of the season because of the issue that you just raised, you think it's possible salt water could have gotten in even from a previous

season >> the year before. it had been working. >> the year before. >> yeah. yeah. >> so you heard these noises when you went down with him and waited a day and wrote out an email to stockton rush and i want to read some of what you wrote in this email once back on land. you said what we heard in my opinion sounded like a flaw or defect in one area being acted on by the tremendous pressures and being crushed. the fact that they never stopped at depth and the fact that there were sounds at about 300 feet that indicated a relaxing of stored energy would indicate that there is an area of the hull that is breaking down, getting spongey. can you explain what you mean by that and what stockton rush's response was to that email? >> well, so i mean we were actually staying in the same house in marsh harbor in the bahamas during this trip and i took a lot of time to kind of

digest the whole experience and send him an email specifically because i didn't want there to be any kind of heated exchange between us. he's not the kind of character that would take criticism very well or -- i wanted to have him have something that he could refer back to and that he could not just start an argument that he would have to read it. and he did not respond in writing. we spoke about it. but we did not speak about it at length but he did take measures. he extended the -- he canceled that year's dives. and he took that carbon fiber too and cut it up, found the defects and made a new one at the cost i believe of well over a million dollars. he was making these tubes out of the exact same material that boeing is making airplanes out of. i think he got the material from bowing or the same supplier. he had an over 20 year background in aviation.

he was a pilot at 19. he made his own composite airplane. and i feel that's also a mitigating circumstance in this all is that his background in aviation caused him to have a -- he was thinking about it from an aviation standpoint and not a -- he switched horses midstream. >> you also wrote to him the other thing you wrote to him in that email is you said imagine the project itself funded when you consider taking dozens of other people to the titanic before you truly knew the source of the sounds. you knew he was under at that time pressure from investors and people high net worth individuals who wanted to see the titanic. >> yes. he was under a lot of pressure. there were i met a lot of people that were waiting to go. and he kind of brought them out there so three i mean they had already given large deposits and

he wanted them to be able to see -- it was also for them i think part of the experience and seeing. they're not just tourists. they're mission specialists so they're involved in the whole process. and they were chomping at the bit. they're just like when is this going to be ready. when? and if memory serves me there was even one person who was terminally ill and if he kept delaying it this person might have died before they even got their chance to go. >> mr. rush told you after later on he told you that there was a manufacturing defect with the titan's hull, the titan you were on and that he made adjustments and made a new hull. did you ever find out -- did you have confidence? double it was appropriate to be taken passengers down in this vessel? >> i felt that i saw one

interview with james cameron and he said i assumed that somebody here was smarter than me. i assumed that stockton with his engineering degree with his large amount of funding from my perspective and he never got into it with me about exactedly how many model tests he had done, where they failed. my impression was that he had done enough diligence that, you know, the lives were not at risk and if you tested a couple models and they went 30, 40, 50% deeper and you saw over and over exactly how they failed, you already know enough to not do i have. i don't know exactly how -- i don't know the numbers. i never went over all the data and i hope oceangate -- i hope this doesn't turn into a huge litigation mess. i hope it turns into a learning

experience. >> carl stanley, i appreciate you being with us tonight. thank you. >> okay. thank you. >> cnn reached out to oceangate about those claims and they said we're unable to provide additional information at this time. we mentioned that some search and rescue vehicles are returning right now but there is activity out of the disaster site. more on that now with tom foreman. we talked about the remote underwater vehicle earlier. talk more about what we know about it. >> i think anderson this may be the most important craft out there over the next week. the odysseus six is about the size of a car, weighs close to

$4,000 pounds. >> how to investigators go about piecing together what happened. how important are fragments of the craft to that? >> everything you said so far leads to why it's important. what they're going to do basically is try as much as they can to gather different parts here. the coast guard, ntsb involved now. these agencies are going to say, look, we want to gather all the pieces we can, put it together as best we can so we can see if there are clues. i was talking to two georgia tech engineers, professors down there, some of the best in the world. both of them said this carbon fiber thing may not be the issue but say the way this all the reports about this are troubling

to them for all the reasons you talked about. repeated stress. being in the water. possibly becoming delam nated. the glue. it's the glue, the epoxy that holds it together. that gets into trouble and they are looking very hard at that in their own observation of it from afar. i'm sure investigators will look at all of that as they put this together. >> tom foreman, appreciate it. thank you. up next, the former commander of the u.s. submarine fleet on the network of sensors that apparently detected the sound of titan imploding. plus, the sinking of a fishing troller in the mediterranean packed with migrants causes hundreds of lives to be lost.

had in place for decades. it was designed as you pointed out to move and pick up on the movement of enemy submarines. if you could hear where they're going and sort of -- you know where one of the enemy's key assets is. basically how it works is that sound travels incredibly well under water and because of that if a few sensors pick up on a noise they can figure out writ is. if all three picked up a noise at the same time it must be equal distance from the sensors but if it's not all at the same time you can use that difference in time to zero in on a location. and that's effectively what happened in this case. they used it to narrow down on the search location. the reason it did not end the search immediately or move it from a search and rescue to recovery is because it was not definitive that audio that was picked up by the navy. they did not know it was an implosion though they passed the information to the coast guard.

it was only several days later when an rov got down there that they put the pieces of data together and realized that noise they heard was the implosion of the submersible. >> has that ever been used to locate a missing submersible before? >> absolutely. several times in the past including in some fairly famous cases. obviouslying the implosion of the submarine makes a tremendous noise so in a famous example in 1968 the soviets lost a ballistic missile submarine in the northern pacific and the u.s. realized this because they saw increased soviet naval activity and went back and looked at the data collected and the different sensors and pinpointed a location and realized that the soviets were looking in the wrong location allowing them several years later to recover part of a soviet ballistic missile submarine. it was considered an

intelligence coup own though it was only partially successful. but it started with this same system or an older version of it i should say picking up on the sound of the implosion and allowing it to help the americans zero in on a specific location just as they did in this case. >> appreciate it. thank you. former commander of u.s. submarine forces and before that submarine forces in the atlantic michael connor certainly understands about undersea detection capabilities. admiral thank you so much for being with us. i won't ask for details but can you talk in general about these listening devices? >> sure. happy to help. i think warren has it right. there are systems located in various places around the world that are of interest too the country. and they do passively detect noises in the ocean usually used

to classify what's out there and can help in situations like this. >> we're told that this was determined to be not determinative and they did not know for sure what it was that the information was passed on to an incident commander. do you know who makes the decision of whether or not to release that information in an operation like this? because obviously questions are raised about why they released the information about days later about sounds being heard that raised hopes of -- that people were still alive and not releasing information about there was this other sound we don't know what it means but just putting the information out there? who makes that call? >> so there are malpractice parties involved in the search. in a situation like this they try to typically flow the information through the incident commander so they have the best information. the incident commander probably

made some decisions about how much of the information they had to reveal. in this case, i think i would suspect and i don't know this for a fact that he found out fairly early in the process that the probability of a carcinomas stropheic event was pretty good. but there's an active search going on and what they probably did with that information was focus the people closest to the titanic looking on the bottom and then cover the other situation where maybe the vessel came to the surface and started to drift and they used other assets to continue that search. to make a premature and possibly wrong announcement that the sub was lost before you knew that for a fact would disincentivize a proper search and i know that if one of my family members was on there i would want all efforts until there was no hope

and i think they achieved basically that result. so i give them credit for the way they did it. >> as someone who spent their life on and under the water what do you make of this whole sort of tourism industry but people who are able to pay a lot of money to go down and take this risk. it seems clearly at this point an unregulated as a professional under water former admiral what do you make of it? >> what's going on here is a very different thing than the way the navy would operate. first of all, the depths they're going to are in order of magnitude deeper than we typically go and the cost of operating deep are -- incredibly expensive. it's a very difficult thing and

it's difficult if you're tremendousing to do it for profit. so we probably warrant pause on how you do it, what you tell your customers, passengers or mission specialists, that result is about the same. >> thank you so much. >> you're welcome. thank you. >> up next, more on what one expert has called large red flags she says were apparent in the design materials in the titan. also breaking news out of russia. accusation prigozhin of the wagner group is launching a coup. the fsb is now launching an investigation into prigozhin. the latest is coming up.

>> looking now at live ping which you ares of the vessels just back from the search area, about 400 miles from the port in st. johns where the oceangate titan imploded. the polar prince is expected

back in port in the hours ahead overnight. earlier we spoke with the submersible expert who tried to flag stockton rush in 2019 about what he believed was a potentially dangerous flaw in the titan. that was a different version of the titan than the one that was now used. he said there were warning signs. joining me now is rachel lance who we talked to earlier in the today. an assistant professor at duke university. she's also a biomedical engineer and has said that the vessel's design materials were already known as a large red flag to people. rachel, i appreciate you being back with us. can you talk about the concerns you had about titan particularly what it was made of not just the carbon but the epoxy between the layers and the attempt to go down to the titanic in a vehicle like this? >> yes. of course. so there were two red flags that i had when i first looked at the design of this vessel. and the first one is exactly

what you mentioned. a lot of the strength of this pressure hull relied on material carbon fire. we know carbon fiber as a light weight and strong material that is used for many applications today. however, once you start putting it into salt water, it changes its properties. the reason for that is because that salt water can create and augment traveling electrons between different types of materials. the carbon fiber gets its strength because these sheets of inner woven threads of strands of carbon are alternated with layers of epoxy and it's this layer cake effect that gives it its total strength. a carbon fiber is not just carbon strings or epoxy. it's both. so when these currents start to affect the epoxy in between the

layers, it starts to break down that layer of glue abe those multi-it will players of glue between them dramatically reducing its strength. it is possible to use carbon fiber under water -- people do it with other applications and there are other ways it can go but when you're deal, not only repeated pressurizations, that will first of all weaken the hull over time but also at the same time repeated pressurizations in salt water you've created kind of a difficult scenario for this material to hold its strength long term. the fact that it passed a pressure test on the first day is not indicative of the length of time that it would work. overall. >> and if it had been rigorously tested over a long period of time which would be both perhaps prohibitively expensive for a business application and also would mean that passengers could not go on for a longer length of time but if it had gone through what others in the industry wanted it to go through in terms

of studies testing stress testing, would the risk of multiple uses over many seasons that would have been greatly reduced? >> it would have been reduced by having intermittent testing. it was never a great material for a submersible in the first place just because this material has been tested before. it has been used before. it has been known to have this property of weakening over time with repeated immersions. >> i understand you're also skeptical of the idea that titan had 96 hours of oxygen on board. why is that? >> well, when we're breathing in an enclosed space and this is one of the major problems when you have a disabled submarine scenario. you're not only consuming the oxygen in there but you're also producing carbon die dioxide and it's the carbon die dioxide that

becomes the problem. when it comes to removing carbon dioxide -- we need a material that looks a lot like kitty litter and therery accouple more advanced methods but they don't take up a much smaller volume and in the case of titan in order to keep those five passengers alive for 96 hours, they would have needed enough material to fill about half of a standard bathtub. this material then gets insulated heavily and needs also to be coordinated with the air flow inside the submarine and based on the publicly available photos, there were no structures attached that meet those volume requirements to give those 96 hours. i would be interested in seeing the internal diagrams for the breathing system but those have not been released.

tonight russian generals are accusing prigozhin of trying to launch a coup. russia's internal security agency has started a criminal investigation of prigozhin. the military vehicles have now been reported on the streets of moscow itself.

all of this in the wake of an alleged russian attack on prigozhin's wagner fighters. in a video, prigozhin calling for retri bugs. bear in mind the two sides of this clash, prigozhin and the kremlin generals are supposed to be on the same side and there's no clear indication of where this may be heading. matthew chance joins us with the latest from kyiv tonight. this is extraordinary. we've been watching prigozhin mouth off against russia's agains and the kremlin policies in ukraine for quite some time now. what is he saying now? >>reporter: well, i mean, it's been more of the same in the sense that we've been watching this simmering dispute between prigozhin, the leader of wagner, and russia's high demand. its defense minister and its military chief who have prigozhin has been accusing of incompetence and mishandingal it will war leading to various

angry tirades he's been posting on social media. there was one actually earlier today in which he took a step further and said the russian defense ministry misled president putin and they sort of lied about the threat that ukraine posed in february, 2022 which led to what was essentially an unnecessary invasion. so he basically challenged the premise of the invasion of ukraine by russia which is of course a big no no as far as the kremlin is concerned. within hours of that, it's not clear whether it's related but within hours of that, prigozhin was back on social media absolutely furious and distraught really because this camp that he said was run by his fighters had been struck with atillerery or an air strike and many of his fighters inside were killed. he was accusing the russian defense ministry of doing that.

he is furious as i say and has rawed to kill russian troops in retaliation for that strike against his own para military forces. that's led to these extraordinary developments of him being accused of launching a cue for russian security services, the fsb and prosecutors have launched criminal proceedings against him and so this incredible tension that we've all been witnessing the past several months is now coming to a head plunging russia into a very high degree of uncertainty, anderson. >> so matthew what are his options? what power -- i mean, obviously he has wagner forces who i guess are under his control. i mean not sure if in a showdown with the kremlin who they would side with. what can he actually do? >> i mean, it's -- well, i mean, we're in uncharted waters at

this point but you're right. prigozhin has about 25 thousand men who are at this point very battle hardined and apparently still -- hardened and are still under his command. of course when it comes to an order to march gns the russian defense ministry it's not clear how many of them if any at all would actually comply with that kind of command. certainly russian generals have come out on state media launching statements on social media as well sort of demanding had that wagner fighters step back and don't sort of make good on that threat. they've obviously said they're going to take appropriate action and i think we all know what that means. if they see it as a threat pose against them. the latest we've heard is from prigozhin himself who has posted on social media in an audio message saying that his forces

have begun entering the southern russian region of rostuv, the region that borders ukraine. they've obviously started coming out of ukraine and heading properly into russian territory. so the next few hours could be really very crucial. >> i mean this is extraordinary. stick around. i want to bring in a cnn military analyst. general, i don't know what to ask. what do you make of this? how serious should russian generals take prigozhin. what's to stop them from just taking him out? and seeing what the wagner forces do? >> couple of things, anderson. i've been tracking this the last couple of hours and it's certainly a fascinating and it's going to get sporty here i think in the near future because part of his no, sirs under prigozhin have allegedly been marching and there seems to binned caters on film of them marching as matthew

just said into the southern part of russia. what's fascinating about that is that they are coming off of the front lines in the southern areas. what is more important is a number of russian generals to include general -- who have been on telegram channels talking about -- telling the russian -- telling the wagner group soldiers to put down their weapons, get back to the front, they are at the zero line as russia likes to call their final defenses prepared to defend against the ukraine an attacks giving that speech while at the same time sending messages on telegram channels and one general i'll mention was part of the coup attempt in moscow as a young officer in 1993. so he was one of the guys that was put in jail by ygo --

gorbechev when he fired on the russian white house, the location of the parliament. this is the craziness of personalities inside the kremlin and the russian military with these private military organizations that are doing the bidding of putin and sometimes get out of his control but it all comes at a very fascinating time when crew janeen forces are just begin -- ukrainian -- where russian troops are needed. so this whole prigozhin action tonight and the reaction by the russian generals are while conf soldiers on the front line. it couldn't have happened at a

more inopportune time. but a very opportune time for ukraine. one last thing i will mention just to throw another wrinkle into this. and matthew can come in on this. every military operation that russia does has an element of what they call deception. and it is the fact that there are so many people on telegram channels and on the internet proclaiming is, they could all be a demonstration i doubt it. i would think that the u.s. white house and it has been said , that they know what is going on and i would almost bet that they know more than what the russians know going on. they are watching this closely to see exactly what is imploding and what may not be imploding on the russian side of the lines tonight. >> matthew, what are ukrainian officials saying? >> as you can imagine, watching

this with relish, their official statement is not there watching this closely but other ukrainian officials have been saying this is basically russia imploding, the best information we have, from the russian defense ministry who have said that the ukrainian forces around bakhmut, which has been a meatgrinder of a battle over the past several months ukrainian forces are now trying to take advantage of the confusion and have launched new offenses in that area of the frontline. so, yes, it is not an opportune moment for the russians but it may be an opportunity for ukrainian forces to gain an advantage. and they are looking for opportunities like this in this counteroffensive. >> thank you so much we will continue to follow this, the cnn investigation about another tragedy off the coast of greece, hundreds of migrants messing after the vessel capsized and sank last week,

survivors who spoke with cnn questioned the official account of the zip wreck raising the question whether the greek coast guard is to blame. details are next. we have got hureds of people here, people who have been displaced but also people who are here looking for family members. looking for relatives. get down, get down, they are asking us to get down. i do believe they are scanning buildings. i'm going to have to keep my voice down.

this is such a delicate operation. we moved out of the city so our little sophie could appreciate nature. but then he got us t-mobile home internet. i was just trying to improve our signal, so some of the trees had to go. i might've taken it a step too far. (chainsaw revs) (tree crashes) (chainsaw continues) (daughter screams) let's pretend for a second that you didn't let down your entire family. what would that reality look like? well i guess i would've gotten us xfinity... and we'd have a better view. do you need mulch? what, we have a ton of mulch.

we want to tell you about a transport investigation as we tried to learn how this occurred, questions being raised about how a vessel crammed with more than 700 migrants capsized and sank in the mediterranean off the coast of greece last week, hunter the people are missing survivors and relatives, speaking with cnn, the fault lies with errors made by the greek coast guard, whose officials denied charges. investigating the story, and this is her report. >> reporter: the desperate

exhausting wait for the promise of a new life in europe. these pakistanis crammed into a small room by smugglers in libya, some believed to be among hundreds presumed dead, these last images before they embarked on their ill-fated journey. about 750 refugees and migrants patent of everything fishing vessel before i capsized off the coast of greece. only 104 survived. and with harrowing accounts of what they have been through. >> i can still hear the voice of the woman calling out for help. they would swim and move them >> reporter: the survivor spoke to us from greece, asking for his identity to be concealed for security reasons. another account obtained by cnn not only contradict the official greek version of events. but would default on the part of the greek coast guard. >> reporter: greek authorities who watched for an entire day,

insisted that it was not in distress. and refused assistance. our investigation tells a very different story. just before 1:00 p.m. on june 13th, the boat was spotted by the eu border patrol agency which said it notified greek authorities of the heavily overcrowded fishing vessel. those on board were in distress, lost at sea with no food or water for days, according to survivors and activists in touch with the bow throughout the day. at about 7:00 p.m., and activist in italy recorded one of the calls capturing the horror on board. as activists repeatedly relayed calls for rescue to authorities, to merchant vessels approached about and instructed with the greek coast guard to provide the boat with food and water. but as darkness fell, 10:40 p.m., a greek coast guard vessel now the only ship on the scene,
