cnn's tom foreman explains. >> reporter: for many years the u.s. reports of people seeing things in the sky. the idea there were unidentified objects up there. now, government agencies in the past few years say there's clear hi something there because we have video of it and too many reports of it but what is it? this is nasa's time to come onboard with a committee having a report saying here's what we think is going on up there. they say some things can be explained as balloons or flights of birds or aircraft. some of it they can't explain. more importantly, they're saying they are trying to put together a road map going forward. a way to combine actual scientific observation of these things, with the anecdotal observation you have. too much of that. too many people with iphones and saying i saw something. maybe it looked like this. did they come up with a general idea of what these things looked like, based upon what they have heard? yeah. they said generally the characteristics of unidentified phenomenon as they call them, are they're round and

tom foreman, cnn, washington. >>> millions in the u.s.outh and southwest are under an extreme heat advisory. more than 38 million americans are under active alerts and warnings while hundreds of thousands are without power. the scorching temperatures are in texas, oklahoma and louisiana. in texas several cities have been dealing with intense heat and the city of san angelo set a new record for its hottest temperature ever on tuesday. the national weather service is warning that daily records could be broken throughout the week with peak heat occurring tuesday and wednesday. >>> and meanwhile in india, officials are investigating the deaths of dozens of people in the northern state that have been linked to a heatwave. at least 68 people died last week as temperatures soared and many others were hospitalized. >> and in another state, at least 44 people lost their lives in recent days. temperatures in some parts have reached 46 degrees celsius, that is more than 114 degrees farenheit. >>> ukraine says that its top priority right now is to k3

joining us now cnn's tom foreman. tom, show us where these discovered parts used to be on the titan. >> reporter: this is really important to the investigation here. first piece they found was this, this sort of tail cone that sticks out here that says "oceangate" on it. then if you take that part away they also found the nose cone over here, which contains that window up front that we've seen so many pictures of. and then they found this part back here. these are both the titanium caps on each end you've heard so much about. the reason they know automatically that everyone was lost once they found those parts is the rest of this is nothing but a carbon fiber tube. there is nothing in there to protect anyone. so those are the three pieces they found. and here's where they found them. we mentioned the idea they were maybe an hour and a half into their descent. an hour and a half into the descent of a two-hour descent would theoretically put them somewhere in this area, ba ballpark. and the titanic is actually in two par

cnn's tom foreman has more on this and he's joining us now. tom, what are you learning? the hours tick down, the questions are coming up more and more about how this reached this point. specifically, how this submersible was developed. you mentioned the employees there and an industry group and there was a letter from the new york times from them in which they said what was happening at oceangate and our apprehension that the experimental approach and developing this craft could result in negative outcome from minor to catastrophic that would have serious consequences for everyone in the industry, and it went on to say your marketing material advertises that the titan design will meet or exceed the dmvgl safety standards and these are standards developed a long time ago for this type of vessel and yet it does not appear that oceangate has the intention of following your class rules and your representation is at minimum misleading to the public and leads a professional code of conduct we all endeavor to uphold. simply put, kate. years ago there were people in the company

tom foreman has a lot more on what it's like inside the titan.he coast guard is admitting even if crews are able to locate the sub, it is unclear if the five people on board can be saved. >> even with the amount of time that's left, say 41 hours or, so if you were to find the submersible at this moment, would that give you enough time to save these five people on board? >> yeah. i don't know the answer. what i will tell you is we will do everything in our power to effect a rescue. >> it's an honest answer. it is a terrifying thought as we think about the fact that there are five human beings there underneath the water perhaps still alive, hoping they can make it out of this alive. some of them paid upwards of $250,000 for the honor of this trip to see the titanic on oceangate. there's a lot to get to. jason carroll is out front live in boston. what is the latest you're hearing tonight? >> reporter: the coast guard is telling us at this point they're going to be releasing to the public a grid they put together which shows exactly where they've bee

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.

tom foreman here is us to help answer. om, is how was an uncertified -- apparently untested -- that's not my definition, that's the definition of others -- how was this certified to bring tourists? >> it's in international waters. it's not flagged to any country. it went out there and did what it did. that's what these deep sea submersibles are able to do now. that may not last now after this happened. the international communities are saying there has to be a standard here. we can't allow this happening. >> let's talk about the design here. there are a lot of questions, not new, raised before this happen but even more so now about the use of carbon fiber and in the form and design as used in this submersible. >> the carbon fiber is really an interesting key to it. the carbon fiber is that main barrel part right there. that's made out of carbon fiber. i just talked to a doctor at georgia tech, he's an expert in carbon fiber and material sciences there, he says carbon fiber actually really can be a perfectly good thing to us

we also have correspondent tom foreman here in d.c. as we're looking at this here, what's the difference between a submersible and a submarine? >> they're all submarines but submersibles are a particular type of submarine. that's will speak to what paula and oren just mentioned about why this is difficult do. a submarine is a big vessel, meant to be underwater for a long period of time, supports a crew of 100, 130 people. and in truth, they don't tend to operate in that deep of water. if you're looking for military subs, they're fairly close to the surface. submersibles and there are robotically operated ones, those are that autonomous but a human submersible like this goes much, much, much, much deeper. yes, it's a much smaller profile vessel. it's only meant to be down for a limited period of time compared to a submarine. it only supports a limited number of people on board. although it has very good movement horizontally and the ability to come up and down, that's its limited scope here. imagine if you had a very, very tall building

tom foreman, cnn, washington. >> and as he reported, while we look to history for a guide, history isng right in front of our eyes. let's bring in david scott bedard. so nice to see you. thank you for coming by here. the entire world is fixated on what is happening in the atlantic ocean right now. even with all the known risks to travel to the ocean floor to see the "titanic," it is still this object of fascination. why do you think the "titanic" is still such a draw that people would take such big risks to try to see it? >> well, adventurers will always take risks, whether it is cli climbing everest or sailing solo around the world. "titanic" is one of those unattainable things for most of us unless you've been working in research and are lucky to dive the wreck in the past. or now of course as these adventurers paid a great deal of money to go down. they do play an important role. they are mission specialists and they do take part in some of the research while they are there. why is "titanic" such a draw? of course she sits majestically on the seabed. incredibly rare for a shape to

tom foreman has more on what it is like inside this small craft. >> oceangate competitions offers you the once in a lifetime opportunity to be a specially trained crew member safely diving to the titanic wreckage site. >> reporter: it may look like a luxurious journey, but ask alex newman. >> i wouldn't call it plush, but it was very comfortable. >> reporter: the quarters are tight he says. hot near the surface of the water and nearly freezes in the depths. propellers to move the vehicle and controls seem rudimentary, although he and the company insist they are adequate. >> not super complicated. they have two sets of fans, up and down and left and right. >> reporter: but communications, that is another story. the craft checks in with the ship above through a text messaging system every 15 minutes. relying on that system for safety and guidance. former navy submarine officer -- >> so all those things we're used to now with gps and wi-fi and radio links do not work under the ocean. and then, you know, the pressure is just immense. >> reporter: oceangate says the titan hull has proven i

cnn correspondent tom foreman is joining us now. tom, what are you learning? the dimensions are, but what are you learning about the technology that was used in this vessel? >> look, carbon fiber is something we see every day, it's in your car, in your tennis racquet, your golf clubs, spaceships, in the airplanes you fly on. carbon fiber is prized because it's lightweight and it's very, very strong. however, it doesn't bend well. if it's under tremendous force the question is can it get so much force that the very fibers of the carbon fiber, the labors -- the layers of it start to delaminate and come apart. this is one of the concerns. filmmaker and known ocean ogg grafr james cameron has some very sharp concerns about this material. listen. >> it's completely inappropriate for a vessel that sees external pressure. you know, carbon fiber composites are used very, very successfully for internal pressure pressure vessels like let's say a scuba tank, you can get two or three times multiple of what you can get out of steel or aluminum for that type of pressure bot

let's bring in tom foreman, and now in the aftermath of the tragedy, how do we know how the hull wassurrounding it? >> we are learning that a lot of experts in the field had raised serious questions about the way that the sub had developed for a period of time, and a lot of it had been surrounding the carbon fiber tube that everyone was sitting in. the carbon fiber is everything, in the airplanes and spacecraft and cars and all sorts of things that you use rely on the carbon fiber, but one of the concerns is that under tremendous pressure, it is too rigid and so that the hull that you are looking into right there, it would not hold up, because it would start to delaminate. so imagine that if i took a book and glued all of the pages together, it would be like a brick and strong for everything, but if i had a pressure strong enough to make the pages separate, it would not hold enough. that is what james cameron had when he talked about his concern. let's listen. >> it is completely inappropriate for a vessel that sees external pressure. fiber composites are used very nice for internal

cnn's tom foreman explains. >> for many years, the u.s.s of people seeing things in this guy, the idea that there even were unidentified flying objects up there. but now, government agencies in the past few years have come around, saying, yeah, there's clearly something there. because we have video of it. and we have too many reports of it. but what exactly is it? this is an acid is time to come on board with all of that, with this committee they put together that is going to have a report out this summer, basically saying, here is what we think is going on up there. now, they are not going to answer a lot of things. because they will say some things can be explained as balloons or flights of birds or maybe aircraft that people did not know were out there. some of it, they say, they can't explain. but more importantly, what they are saying, is that they are trying to put together a road map going forward. a way to combine actual scientific observation of these things with the anecdotal observation you have -- because, the problem you have

tom foreman is out front. >> the fact is, trump cooperated, right? er in the beginning of the year. those 15 boxes, and then they harassed him further. >> that is tom fit, and conservative activist, head of the right-wing judicial watch, and a man some trump insiders sale hate glam the former president of the very trouble he is facing now over those papers at mar-a-lago. acclaim 15 does not like. >> i want to start yelling about tom fit in, as opposed to the justice department who was going to in indict trump and entrap him in a wildly abusive. way >> i did everything right in the indicted me! >> sources close to the former president say last year as a government repeatedly asked for the return of the documents, and someone trump's team trying to work it out, fitting told trump to give nothing to federal officials. >> they lied to him about the law, or must lead him about the law, and of course that led to the boxes being returned, them finding allegedly classified information, which were really personal documents of. his >> tom fitton and that group,

joining me is tom foreman. so based on what we learned, we learned a lot in that press conference about what happened here. if we could put up a picture of the submersible itself. the headline seems to be, they found these, in fact, two debris fields and the debris field showed pieces of the pressure hull, which is a capsule sort of picture like a medicine capsule shaped object in the midst of the larger object there, catastrophic means implosion at those departmths? >> if you haven't found the bodies or seen the details how do you know? here's how they know because of what they found. if you look at this diagram here or any other one we want to bring up here, see on the left it says oceangate, they said that was the first thing they found, part of the tail section. >> this lets you see what is the pressure hull and that is the capsule sized piece inside. >> with the people inside. first of all they found that covering on the back there that says oceangate "titan" based on what they said, or a portion of it. th

tom foreman -- >> you can't be outside and this, you must be inside a vessel. >> it raises questionsing, where their heaters inside their with electronics, tom foreman, thank you for bringing that all down for us. joining us here once again tonight is someone with more than just a professional interest in the search that is underway. oceanographer and water search expert david gallo, whose friend p. h. is aboard the tie in. david, i want to start out on the noises, because they were picked up by sonar. last night, we were told that they happened again today. so far, they have not yielded any leads that we were told up by officials, but you see it as a hopeful sign? >> very much so, until we heard about or heard these noises, my optimism was taking a real dip. even after i was told that there were these noises, we had that situation before in both air france four for seven, looking for the plane. there were voices heard with malaysian air three 70. there are horses heard that turned out to be from ships that are looking out there and not from, certainly not from pinning from a plane.

and now at least in a way, live pictures. >> tom foreman, thanks for that report. >>> this will rockhouse sotheby's is selling 1,500 items from the late queen front man freddie mercury later this year. buried in the collection is a secret, an early handwritten version of the ballad bohemian rhapsody reveals its original title was mongolian rhapsody. also included are draft lyrics to "we are the champions," "don't stop me now," and "somebody to love." >> the lyrics are amazing because they show how hard he worked at what he did. he didn't just kind of write things down. you can really see that the concentration, the thought, the care that went into crafting these lyrics. all of these objects give us a little piece of the story of who he was. >> the winning bidders can take home other personal effects including the singer's mustache comb, sunglasses, well-worn sneakers, stage costumes, and works of fine art from the singer's estate in london. mercury died in 1991. his possessions are being put on sale by his close friend, mary austin. >>> i'm laila harrak. do stick around. paula newton

. >>> now, let's go to tom foreman to explain what was involved as the search intensifies. we understand so many different assets are being used to search here. what does each one do? >> our team out there has done a great job of keeping track of all this. we know about the air support. poseidon, able to scan for submarines. the ships on top of the water. all of them have ability to reach in and figure out what's going on below the water. when you get really deep, you talk about the probes that can drop down and listen to things going on. side scan radar they're able to take sonar pictures. you may remember from the malaysian air flight. if you can get pictures in this manner. it helps you go after a target. how good can the pictures be? it can be astonishing. none of the pictures we're showing is from the site. if that happens, you start going to robotic devices. from france, the victor 6000. this can go to 20,000 feet. it's a remarkable craft. it has robotic arms, it can cut loose. it can shoot video of it. this can do remarkable work. it can only do that work if it knows

tom foreman, thanks.was interesting, even on the point is talk about debt, right, he's said obama increased the debt, and then trump increased more. i mean, i did notice several points where he made a point of using facts, and he did use them accurately. >> yeah, he sure did. let's talk about this in my panel, christie took aim at both trump and biden on concerns that either one of them would become the oldest person ever elected president. take a listen. >> if those two people are the nominee is, they are going to be a combined 160 years old on election day. i'm sorry, guys, nobody beats father time. nobody does. i'm different than i was when i first got into office 13 years ago, okay? i'm different, i feel it. and i cannot imagine 20 years from now, 22 years from now when i'm 60 years year old, at 82, being president of the united states? >> our panel is back, and john, he referred to both biden and trump as being bass there's sell by dates. >> he said one of his children 's called him ageist, any joke

if you've lost track of all of the different investigative threads, tom foreman is at the magic wall to catch us up. tom? >> brad wrathens burger said he felt threatened, when th then-president trump called to find enough votes to win in georgia. now, he's joined a long line of republicans to overturn the 2020 election. among them, rudy giuliani. once-lawyer. former vice president mike pence. chief of staff, mark meadows. former aide, steven miller. former deputy chief of staff and deputy director dan skcavino. on and on it goes. a lot of trump insiders being asked about what they saw and heard about the undoing of a fair and legal election. the scope of this is notable for its geography. investigators asking about possible schemes for fake electors and false claims in georgia and pennsylvania and michigan and wisconsin, and nevada and arizona and new mexico. all of this against the boiling background of the other cases, the former president faces. that indictment in manhattan, accusing him of falsifying business records to disguise hush money payments. the indictment in federal court

tom foreman explains how the system works and how it could deepen the world understanding of the redspace agency builds the first live transmission of images from mars. life is a relative term here. these were taken about every four seconds, and then they were transmitted back at over 187 million miles, that took 16th minutes per picture . so, not lifelike we would know it. it is taken from an orbiter , not something on the surface. in some ways, underwhelming. really interesting, because this was to celebrate the 20th anniversary of the mars express orbiter. it's been up there going around the planet helping us understand what service conditions are like , what the geology is like. helping doing researching into water and ice on mars. the general geology on mars, and you put that together with all of the other exploration of mars, that has been done by other probes and satellites, some from nasa, et cetera, and looked around, it is deepening our knowledge. keeping our knowledge , like plato's cave of enlightenment. the big asteroid belt and jupiter. is paving the way from what we ne

cnn's tom foreman is at the magic wall to explain some things to us today. what was found today?> what was found was what we needed to know what happened really. they found this part first, the sort of tail cover. they say the second thing was this titanium nose cap that contains a window he was talking about in the video and they found the back cap back here. as soon as they found this, they knew everyone had perished because this is nothing but a titanium tube. without a cap on either end that's the end of it because there's 5,000 pounds of pressure for every square inch down there. knowing that, also, based on the time when they stopped getting communications from the people on board, now you match that up with the sound signature. you mentioned the navy recorded and you get closer to knowing this probably happened somewhere around this depth. it's about 2 1/2 miles all the way down. somewhere in that area it would have happened and the debris landed out here off the bow of the titanic. there's two parts. one half is about a half mile away. the bow is up in this area. all of t

tom foreman joining us on this. ave this giant asteroid. how close are we talking here, tom? >> well, for something that big, it's pretty close. yeah, that's the comparison. look how big this thing is out here. and if you look the actual measurement of it, it is fairly far out there, around 2.5 million miles away out there. but point to bear in mind, that's about ten times as far as the moon. is that pretty far away? it's pretty far away, but nasa's threshold for what they consider potentially hazardous is 4.7 million miles. big distance, but in the cosmic sense, not that big really, you know? >> yeah, armageddon is my reference point. this feels farther afield than this. what makes this potentially hazardous? >> two things. one, this. the location of it. the fact that it's coming fairly close. this has been here six times before since the early 1900s and it will come again. >> it's not getting message. >> no. but also it has to do with the size of this thing. 500 feet pls in size. this three times as much. i will no

tom foreman is here now. the depth of the "titanic" here at 12,500 feet.before but nothing near that depth. >> nothing even close to this. the truth is there aren't that many rescues attempted underwater because you don't run into these circumstances that often. let alone at this depth. are there any pieces of experience that we could gain knowledge from based on past attempted rescues that could have factored into this? >> there are pieces, yes. and parts of that equation. right now, you're in this strange two-track world. you're waiting to find out what the debris is. does that tell us the search is over, tragically in its own way? but in the meantime, everyone else has to go forward and say, we must assume that they're still down there. that there is still a rescue to be affected here. the truth is, you have to bring all the bits of information together and see if you can make them work. and that's a come america equation. >> racing time, the ocean of unknowns, underwater rescues are inherently complicated, dangerous, and the deep sea makes it all harde

cnn's tom foreman joins us now. stand what these junk fees are. >> i'm a music fan, you're a music fan. you want to go see a big act, taylor swift is an example here's what happens. you say i'm going to cut loose the tickets here at $470 per ticket. not me. but look what happens after that, you agreed to pay this and suddenly you pick up almost $600 in additional fees that you didn't see when you agreed to this. >> and this is kind of crap also, like the service fee this is what's supposed to be included in this. >> that's what they're going to give you this. it's not just the great big acts. look at this. this is really reasonable. you can go and get a ticket $20 apiece, $80 for one ticket. look at this. the fan posted it because there were more charges and fees than there were for the tickets. that's what the white house is going after, and consequently the white house has called in these groups with the white house to say they have agreed to up front pricing laws. they want people to see it. what that means is if

tom foreman joins us now with more on the challenges involved. tom, there are huge challenges obviously. we don't know how deep this vessel was when contact was lost or where the currents may have taken it. just try to put into perspective how deep down this vessel might have gone. >> this is an area that is so incredibly forbidding and so terribly deep. statue of liberty, eiffel towel, mt. fuji, it's important to bear in mind, before you get to the titanic, this is roughly where the deepest underwater rescue ever occurred in 1973, at that level. this is roughly where nuclear subs operate. so, this gives you an idea of how forbidding it is and a three dimensional environment, anderson. you're right. we have no idea where it may have gone since being up here on the surface. >> it is incredible when you see -- when you put it into perspective like that. the different types of vessels that have been called in to help -- obviously there's air assets, there's sea assets. >> absolutely. and right now, those that are on the surface -- the polar prince wa

tom foreman explains. >> reporter: for many years, the u.s. government just denied all these reports of people seeing things in the sky, the idea that there even were unidentified objects up there. but now government agencies in the past few years have come around to saying yeah, there is clearly something there because we have video of it and we have too many reports of it, but what exactly is it. this is nasa's time to come on board with all of this with this committee they put together that will have a report out this summer basically saying here is what we think is going on up there. now, they won't answer a lot of things because they will say some things can be explained as balloons or flights of birds or maybe aircraft that people didn't know were up there. some they can't explain. but more importantly, they are trying to put together a roadmap going forward, a way to combine 2u8 sci actual scientific observation with the anecdotal observation. because the problem is they have too many people with iphones and saying i saw something and m

cnn's tom foreman is at the magic wall to explain some things for us. tom, what we found today?> what was found was what they needed to find know what had happened, really. they found this part first, this details cover back here. that was the first thing they came up with. they say the second thing was this, this titanium knows cap that contains a window that he was talking in that video. then they found the back kept back here. as soon as they found this, they knew that everyone had perished because this is nothing but a tiny alien tube here, without a cap on either and that's the end of it because there is 5000 pounds of pressure for every square inch back there. knowing that also, based on the time when they stopped getting the communications from the people on board, now they match that up with the sound signature that you mentioned the navy recorded and you get closer to knowing that this probably happened somewhere around this depths, around two and a half miles, some are down this area is where it would've happened and the debris landed out here. the titanic off the bow

tom foreman has more. >> the european space agency is billed as the first live transmission of images48 seconds. still fphotos were transmitted back and 18 million miles took 16 or 17 minutes per picture. and it was taken from an orbiter going around the planet. it wasn't something on the surface. so in some ways underwhelming, but in other ways, really interesting becauses this was to celebrate the 20th anniversary of the mars express orbiter, which has been going around the planet, helping us understand what surface conditions are like, what the geology is like. it's helped to research ideas to water and ice on mars. and the general geology of mars. when you put that together with all the other exploration of mars that has been done by other probes and satellites, and looked around, it's deepening our knowledge, deepening our knowledge of this planet, the next one out from the sun beyond us, beyond that big asteroid belt and jupiter. it's deepening our knowledge of this planet and paving the way for away we need to know if we actually want to send people on that roughly 9-month voya

tom foreman has a look at five of the most dramatic underwear rescues. >> reporter: racing time, these trying to find the titan on sub, it's dangerous and the deep sea makes it all harder. steven mcginty knows. >> it's hard to imagine two miles of water above you, the immense darks in, no natural light. the weight of the crushing weight, so you're operating in pitch darkness at a depth that many things will fail. >> his book "the dive" is about the deepest ocean rescue to date. the pisces 3 was off the coast of ireland. for three days, ships, submarines and robotic vessels struggled to get lines attached to all up the submersible. finally, success. >> did you begin to wonder if you would get up? >> not at all. we had about a day's supplies. we could talk to the surface all the time, so there was no trouble at all. >> reporter: not exactly. like the titan, the pisces had limited area, just enough for 82 hours, the two men extended it by lying still, not talking. when they finally emerged after 84 hours, they only had enough for 12 minutes more. how different, the pisces was located qu

joining us now with that and more, cnn's tom foreman. obviously everyone is hoping for the best.ell this operation, how does it compare to ones we've seen in the past? in these previous deep sea rescues? >> it does not compare. we can try. but the closest you can get is the pisces 3 in the early 1970s. this was off the coast of ireland. there were two experienced sailors on board. they went down into the water. they were 120 miles out from shoreline in ireland there. the "titan" is 425 miles out. they had communications the entire time. even though they didn't know where this vessel was for a while, it didn't take them that long to locate it. we have no contact with the "titan." there is no communication and they have no idea where it is. and importantly, the pisces was in 1575 feet of water. the "titan," look at this, this is so, so much harder to work down here than over here. and this again is the deepest there has ever been a rescue in the oceans of the world. >> it's not even a comparison when you look at those factors. and we know that the "titan," when you look at the figu

cnn's tom foreman has more. >> reporter: the european space agency bills this as the first-ever liveabout every 48 or 58 seconds still photos, then transmitted back and over 187 million miles that took 16 or 17 minutes per picture. so not live like we know it, and it was taken from an orbiter going around the planet, not on the surface. in some ways underwehelming. it helps us understand what surface conditions are like, what the geology is like. it's helped to research the ideas of water and ice on mars and the general geology of mars. put that together with all the other exploration of mars that has been done by other probes and satellites, some from nasa, things that have landed on the surface and looked around, it's deepening our knowledge of this planet, the next one out from the sun beyond us. so it's deepening our knowledge of this planet and paving a way for what we need to know if we actually want to send people on that roughly nine-month voyage depending on the position of the planets and have them walk on this very surface that we've only been able to see in pictures. now,

joining us now cnn's tom foreman. the space inside has been compared to the interior of a minivan, very small and uncomfortable, claustrophobia inducing for some. >> i talked to a man who went down two years ago. he said even though it's close it's comfortable enough. and i asked him specifically about some of the video we've seen talking to stockton rush about the controls of this. look at this piece of video. >> and yet i couldn't help noticing how many pieces of this sub seemed improvised. >> i got these from camper world. we run the whole thing with this game controller. >> come on! >> it seems like this submersible has some elements of mcgyvering jerry riggedness. >> the pressure vessel is not mcgyver at all because that's where we work with boeing, everything else can fail, your lights can go, your thrusters can go, you're still going to be safe. >> that video raised a lot of concerns for a lot of people because you're saying what about the back up. they use this xbox sort of controller but they also can go past

now let's go to tom foreman at the magic -- to explain what is involved as this search intensifies. so, tom -- so many different assets are being used to search here. what does each one? do >> our team out there, jason and all the others, have done a great job keeping track of all this. we know about the air support out there, things like the poseidon, capable of scanning for submarines. that is above the water, obviously. the ships out there on top of the water -- all of them have some ability to reach in and figure out what is going on below the water. but when you start getting really, deep start talking more about things like this. these probes that they can drop down, listen for things that can go -- and particularly if you start talking about things like side scan radar, they're able to go down and actually take sonar pictures of the bottom of this. you may remember this from the malaysian air flight that became lost and all the searching there. these this type of thing there. what can you do with this? well, if you can get pictures in this manner, then you can say, well, we do

tom foreman, thanks so much. >>> in the next two hours the leaders of two of the largest democracies entry into the united states in 2005 for his role in anti-muslim violence that killed more than a thousand people in india. up until today president biden has hosted two other state visits one for the french president and the other south korea. biden sees india as the most important strategic partner for the united states in the 21st century. what is the white house hoping to get out of the visit, arlette? >> reporter: president biden is navigating a fraught situation. there are concerns over the prime minister's human rights record as well as this drift towards authoritarianism seen in his government. on the other hand, the president and white house view india as a key strategic partner in their overall asia policy. especially when you think about russia and china and the influence that they have had in the region. so that is why the white house says the president has invited modi here to the white house for the state visit, even as he is facing criticism for hosting such a lavish af

>> yeah, tom foreman, appreciate it. that's really a helpful look.th their insight, friends with one of the victims. and rachel lance, biomedical engineer, who studied sub disasters. i appreciate both of you being with us. captain mclaren, i saw you said you were angry as hell about this and it didn't have to happen. can you just talk about that? >> exactly. i mean, anderson, we can see two or three years ago, when this thing was being developed and advertised, certainly, you know, i'm a member of the explorers club. i'm a former president. i had at least three people ask me what i thought about diving on it. i said, absolutely not. don't do it. and i explained to them just what i was hearing a few minutes ago. the uncertainty of using that carbon fiber. but more than that, i was more concerned of the sealing of that with the titanic domes and then that big dome, much greater in diameter and lesser thickness than you encountered in other submersibles. there's thousands of ways water could have gotten in there, and i was sort of interested in that las

let's go to tom foreman who was outside at the magic wall.pears that what this submersible -- it is very crucial. can you show was what was found and why that immediately meant that the people inside had perished from a catastrophic implosion? >> sure. this was presented by a sleek model of simplicity, a smooth tube inside where people could see right out onto the to tannic from a big window out there. unbelievable views. what did they find that made such a difference here? when they were investigating, the first thing they found was this tale covering back here. then they found this nose covering down here and then they found a similar one which was hidden underneath this. that told them that the tube itself was open on both ends and that alone assures them, even without finding any other evidence, nobody could have possibly survived. >> in terms of what it was made of, they talk about it in their own right and dimity that they showed that it was experimental. what was so experimental about the titan? it with ink that all deep-sea subs are i
