cute, but one fan noted, you can lol, but she can chortle. jeanne moos, cnn, new york. >> i am glad jeanne mentioned those claws, every cute shot it was like oh, there is the talons, all right, thank you for joining us. "ac360" starts now. good evening, 8:00 p.m. here in new york, 9 in south korea, the death toll climbing, a troubling new fact emerges, the first distress call was made by a young passenger, not a crew member. breaking news off the coast of australia, and coming to close, the entire search effort could be about to take a major turn. and he says he flew 2500 miles before the landing, what he was doing before the american airlines flight and where a teenager was really trying to go.

we begin almost a week to the minute, out of south korea, the death toll rising and it could go higher. now, they are searching the cafeteria where so many of the high school students were believed to have been. tonight, there is evidence that it simply did not have to end this way. the latest, one south korean boy's simple message, help us, the boat is sinking. his fate is unknown. the timing is simply stunning. that is because he said them long before helicopters were launched, before rescue ships arrived and before the evacuation was ordered. and here is the kicker, before the crew's ship even got on the alarm and voiced their concern. his voice was picked up after he dialled the korean equivalent of 911, the exact same thing happening on the costa concordia. and today, the sad discovery of more bodies.

our kyung lah has more. what is going on with the effort right now, i know the death toll has risen pretty dramatically today. >> reporter: it has risen to 128, anderson, but it is still a frantic search, and you can tell just by looking over my shoulder. if you can see there are a number of divers who are parked right at the spot where the sunken ferry is, 65 feet below those buoys and the orange inflatables. some of them are not filled with people because those divers are under water right now. this is dangerous, this is very, very arduous. they can't see more than a foot in front of them combing through this area inch by inch. and because they can't see they are worried about their own safety, arres well, because the can be hit by floating furniture. now the navy did say they have

six divers who they treated for pressure issues. they, anderson, have been seen inside pressure chambers in order to be able to continue to dive. so a very difficult and dangerous task still happening here off of jindo island, anderson? >> and there were more arrests today of crew members, correct? >> reporter: yes, two more crew members, bringing the total number of arrests to nine. this is certainly looking more like a criminal investigation every single day. and we got a little clarity from the crew members about what happened in the final moments. the big question, why went the life boats deployed? well, one of the crew members said that he or she simply couldn't reach it. the button was too far away because the boat had already listed to its side. the natural question, why didn't you hit it sooner? we don't know that. the other thing we did learn is that the crew members say it was not that they hit anything. it was the balance of the ship felt wrong.

anderson. >> and the ships behind you seem pretty widely spaced out. why is that? >> reporter: because we're looking at now a week. it has been a week now since this accident happened. take a look, you can see that there are a number of ships all around us. some of those ships, especially the blue ones have trawlers out to their side, large nets and they're going fact and forth across this area, why? because of bodies drifting out to sea. that is the type of horror the country says they simply can't stand. they want to bring the bodies of the 15 and 16-year-old children back home. anderson? >> kyung lah, i appreciate it. i want to bring in the maritime safety expert, jim staples. and president of security dynamics and retired navy seal, brandon web, joins us. and the idea that the young man

missing now on board the ship was able to call the korean authorities and sound the alarm three minutes before an actual alarm from the ship came does that surprise you? >> well, absolutely, disheartening, just shows the indecision on the crew's part which again goes back to the training. we need to find out where the captain was at the time this call was made. and to be fair to him we have to know if the captain was on the bridge at the time. i don't have a time line, but yes, this is especially disheartening, especially when a young boy makes an emergency call over a seasoned captain. >> and is there a procedure for calling authorities? >> i read that it is the captain who in terms of the ship personnel, the captain has to make that distress call, is that true? >> generally that is true, the captain is supposed to put out a may day call. >> so somebody on the bridge would wait for the captain to decide to make that call? >> again, it would depend if the captain was incapacitated at

some point. if the captain was killed in an accident then somebody else would have to make the decision which would usually fall to the second in command. which is the ship's mate. >> so if you're the captain, you're very much in tune to the ship. if you're down in your compartment you can sense something is going wrong and call up to the bridge. >> absolutely, anybody will tell you if they're sound asleep in the bed they will know immediately if they took too sharp of a turn or if something shut down with ventilation, if you're on that ship for a while you really know your vessels. >> kyung, we have video of the life rafts, you can see almost all of them are not actually deployed. now, the crew said they tried to make it to the rafts. but that they were slipping and that they couldn't.

what does that tell you? >> well, it seems to conform with everything we're hearing now from crew members who have been rescued. that the captain waited too long to recognize the danger that the vessel was in. and the -- alert to evacuate the ship was not given until the vessel was already listing at 5-plus degrees. now what you have to realize is that with this ship unlike some ferry ships you have, for example in the baltic, where you have life boats and life rafts. in life rafts you can actually put the crew in, with the life rafts they have to be manually released from their lashings and pushed into the ocean where they would then deploy using co-2 cartridges. >> they're all scrunched up, and you say with the co-2, they have

to be inflated. >> they have to be pushed over the side of the ship, some meters, 35 feet, where they would then deploy and the passengers and crew would have to get down the gangway to the water line, or in a worse case situation actually throw themselves off the ship and then swim to the life rafts. so life rafts are a far more precarious way to evacuate from a ship than a life boats. but as i said, the sewol didn't have life boats. >> and now in the cafeteria, it is believed a lot of the missing bodies may be there. again, this is a delicate question, but is there any way at this point that survivors could be found? could there be an air pocket a week into this? >> brandon, can you hear me? okay, i think we're having trouble getting to brandon. captain staples, the idea that the ships have life rafts rather than lifeti boats, i mean, woul

you prefer to have life boats on a ship? >> well, that depends, it depends on the distance it is running. i have always been first to go to life boats before the raft. life boats, like the guest prior to me said they can be mounted on the vessel. you can enter the life boat on the vessel and release them from inside the life boat. so it is an easy way to get off the ship. with the life rafts they're sitting in a metal container, like a cradle. and they can either have a ladder to come down or jump into the sea. but a little more difficult to get into a life raft than a life boat. >> brandon, i think we got you back, the divers have made it into the cafeteria. we believe that is where a lot of the people could be found, is there any way that there could be survivors, could there be an air pocket into this?

okay, again, i'm told we don't have brandon. we actually learned the ship did not make a sharp left turn, captain. that it made what they call a j turn. have you heard that expression? >> that is the first time i heard the expression j turn, there are two types of turns to do, a round turn or a williamson turn, and that williamson turn is generally done if a man falls off the side of the ship. the reason for that is so they don't get chopped up by the propellers. >> but a turn like this would not explain why the ship would list. >> if they took a turn like this proves the point he had a major stability problem with the ship. i would be very concerned about the stability when the vessel left the port. >> and kim, we're told there was no passenger safety briefing for the passengers. but you said it could have to do

with the current rules, but they're not actually in effect until next year. >> well, yes, actually it goes back to the titanic. as a consequence of the titanic disaster there was an international convention that korea is a signatory to that steve na established the briefings for the crew that needed to be on the vessel. and in this case we know that as a consequence of the costa concordia. she left port and was not obliged to give a safety report, a briefing, where to find the life preserver, within 24 hours until the departure of the port. and now, you now must give a safety briefing prior to the vessel departing or as she is departing. but here is the thing, that doesn't go into effect until

2015. and that is very little help to the people who lost their lives on the sewol. >> we'll take a quick break, let us know what you think. just saying the remotely operated vehicles making their way through the ferry looking for anybody underneath, so far finding only bodies. also tonight, the big changes that could be coming perhaps in a matter of hours. the search for flight 370.

they're searching on the south korean ferry, watch this. you're looking at an rov, a remotely operated vehicle, snaking its way off the coast of gloucester, massachusetts, when it comes to shipwrecks, this machine is a work horse. it can stay under water for days at a time, maneuvering its way through tiny openings where human divers either don't fit or it is simply too dangerous for them to go. >> so to go forward, it is very, very intuitive, very user friendly. to back it up, you're going to back it up this way. >> it is like a video game. rhonda minese is a pilot. she works for the company that builds the rovs, the robot is directed by an rov pilot at the surface moving at two knots per hour. even in murky water or at night, the robots can see. they have lights and special low visibility cameras.

and if that is not enough they have sonar, too, which can pick up images up to 400 feet away and feed them back in realtime. >> so you can see the stern of the vessel. so you can see how the back of the boat is that square shape. and that is what we're aiming at right now. >> reporter: a simple turn of the knob on the side of the controls and rhonda sends the rov for a deep dive. she rolls it back to return to the surface. so whenever this mini rov is used it is moved into the water through a rope line. and you can see the water we're on is only about 20 feet deeper. but if this were going to be deployed to search inside the sewol ferry that would not be a problem, because this mini rov can actually work in water as deep as a thousand feet. keep in mind, divers can safely go down only about 130 feet. and the robots can swim upward

inside a ship, too, just as divers in south korea are doing to reach the upper floors on the doomed ferry. if you want to get to a higher level on say the ferry, could the mini rov actually climb? >> yes, they would have to have a really good idea of the blueprint of the vessel. because it can be very disconcer disconcer disconcerting, actually like that where it is flipped. and some doors can be overhead. >> reporter: and if the mini rov does find anything, it is small enough to pull a human grabber on its own. >> and you're actually with the rov, can you show us more about it? because the technology is fascinating. i have never seen this. >> it is fascinating, we worked with it today. over here, it is one of five thrusters on the rov which would actually send it back to the

surface. here is the video camera that it has, as well. and this is the grabber that i talked about with the piece. what is interesting, anderson, they come in all different sizes and shapes and have different functions, as well. some just grab items like we mentioned which is what a grabber does. others can actually cut things, others can tie a line onto a vessel if it is a small vessel and pull it out of the water. and the others can be used to recover bodies. in terms of what this would be doing in south korea and the ocean there the first thing it would do is probably pull out all the furniture and all the large debris, i'm told that would block the divers and make it safer. the next mission would be a re-con, to go around the ship and ferry. that way the divers would know where they're most needed and assess the situation better. >> all right, randi, appreciate it. and looking into the delicate under sea operations, with our panel. brandon, let me start off with

you. first of all, we keep hearing about all the debris in the water, the blocked passage ways. how useful is an underwater vehicle like this? >> well, it is a tremendous asset, any time you have a rescue operation in open ocean with visibility near zero, it is incredibly tough for these divers just to maintain their position and just to let alone figuring out where they're going. so having a device like this is just a tremendous asset to really speed up the search. this is a massive ship just about 500 feet in length. so it is an incredible job that these guys have to do under really harsh conditions. >> yeah, a lot of the volunteers, it has to be so disorienting, i'm a diver, to have that low of visibility around you, to not see a foot in front of you. to have all of this debris and human bodies trapped underneath all of this wreckage. can you describe what diving under these conditions is like? >> well, even -- you know, we do

a lot of diving in ports where you have similar conditions, near zero visibility. and oftentimes, you lose track of what is up and what is down. so they're really going -- >> you get disoriented, you can't tell what is up and what is down? >> yeah, absolutely. a lot of the diving, there is no bubble bubbles, you get disoriented. you really sometimes have to follow the weld of the ship's seam just to find the surface, to find yourself -- to get up on the surface. but you know, listening to the conversation earlier, you know, i -- as i understand it, the third mate was at the helm of the ship. and i grew up working on charter boats as a kid before i joined the navy to be a s.e.a.l. i was about to test for my captain's license. but it just really seems from what i know of the time line and the captain who was on the bridge for 20 minutes and just didn't make a decision.

and as a parent myself, you hear about the kids making the phone calls to their parents, it just seem s like indecision on the captain's part. >> because captain staples, there was time for at least evacuation or at least mustering. the ship didn't go down in a matter of minutes. >> without a doubt, there was plenty of time to get the life rafts deployed, which should have been done. and again, to have a young school child make a call before the seasoned captain, that should tell you something like that. that the captain was very indecisive. >> and is the captain going to see better than the diver? >> again, the limitation is not only because of lack of light but the amount of silt you have down there. but i applaud the use of this rov because you know, we have to be realistic. we're entering into a phase now that is more recovery than it is rescue. this is almost a week into the

event. because of hypoxia, because of cold injuries. because of the lack of hydration. all of this really points to a fact that we have no now look at a risk analysis for the divers. this is extraordinarily stressful on these individuals. i know that navy divers that have been involved in rescue efforts in the past that were much shorter and much less stressful than this ended up having to have psychological counseling from this, because it was so disturbing for them. and risking lives when you have technology available instead i think is a good move on the part of the south korean government. >> i think what they're doing and the heroism to do this, they're doing it around the clock. just amazing. >> and you can learn more always by going to cnn.com, and just ahead, the breaking news for flight 370. the unmanned bluefin drone

breaking news tonight, ten meanwhile aircraft, and 12 ships will help in the search for flight 370. the search could get an entirely new focus. more on that in just a moment. as you know it has been six weeks since they have been looking for any sign of flight 370. some family members and family

members hope that maybe legal pressure can get some help from the national transportation safety board, preventing the lawyers from contacting people who lost loved ones in the flight 370 crash. the time period has now passed. the families can file suit against boeing. as for the search effort itself, remnants of a cyclone have slowed results. cnn's michael holmes is live in perth, australia, so what more do we know about the bluefin search? they're running out of territory. >> reporter: yeah, literally, the focused search area that we have been talking about over the last week or so as you point out, more than three quarters of it covered and still nothing found. no sign of mh-370, no word on the data results from the flight 370 mission, but the previous efforts have turned up nothing, anderson. >> and what happens next if this

next 20% gets searched and there is nothing? >> reporter: it is not looking good, is it, for that particular area? the search leaders told us off the record that they were very confident they were in the right spot, given those acoustic signals they had picked up. but they were not going to give up, already the discussions we mentioned the areas of about 300 miles by 30. much bigger than the current one, that could be next, although nothing has been decided. the discussions between the australians and malaysians on issues like who would handle any debris if it is found. the delicate issues of human remains s and how best to deplo resources and bring in more resources if that search area widens, anderson. >> all right, joining me now, cnn analyst david gallo at woods hole oceanographic institution.

and mary schiavo, who represents victims of traffic accidents, richard, in kuala lumpur, and the malaysian authorities are working out a formal agreement for the key aspects of the search and rescue. i know issues should be fairly straightforward. there is also issues of widening the search, what would that look like? >> well, that of course, you're riot anderson, that is the interesting part about it. because that is the part where they will have to re-appraise the evidence from inmarsat. the pings that they have already heard and decide whether or not they still have the same credibility and confidence in that data. and if they do have confidence in it, the same level, how do they expand the search? probably northwards up the arc,

towards the sixth full ping. but to do that would be a fairly dramatic escalation of the search and require more assets because that search is 700 miles long. >> and david gallo, if the bluefin doesn't find anything in this search area, i mean, is it possible it missed something in this targeted area or is the technology so good there is no way it missed something in this area? >> well, anderson, when you search with sound and sonar at this depth and terrain it is always possible to miss something. i'm sure they're very careful and looked at every spot twice, in overlapping zones, it is possible they could have missed it. but i would have a real hard time giving up on this site so soon. so i'm very interested in what pans out in the next couple of days. >> so you say if the rest is not found in this targeted area you would not necessarily give up.

>> i just don't know how you give up in this area if they're so sure of these pings. i am just not sure if they walked away from this and steam ahead of this, and this arc, i think this area -- not knowing exactly what went on from there just from what i do know i have a hard time giving up on this area without looking at a harder area, of what they may or may not have missed. should they make this bull's eye better? >> if the satellite data is accurate, and the pings were in fact from those black boxes, the searchers are presumably close. >> well, they're certainly close. but we've heard a lot of interesting things about the sounds of the ocean and the effects of the pingers and so forth. there are a lot of things they can do. one of them was the frequency of the pings. have they tried to put the pinger in and checked the frequency. what happens when the battery is

out? does it really do great? once this search area is exhausted they have time to do other experiments. but one expert had commented that because of certain layers in the ocean, sounds can travel much farther than ordinary, so they would have time to literally put a pinger down and see how far it travels and how far they must expand the search. so there are a lot of things they can do, not just refining the inmarsat data but expanding their knowledge in this pinger part of the ocean. >> and david souci expects ongoing data by a team of experts in kuala lumpur to further revise the search area. how much more refined can they get? >> you know, i don't see how they can get much more refined. remember, the ocean shield, the ship, went out there and picked up the pings, very confident in that data and it has proven out.

i'm with david gallo on that point. to give up just seems counterintuitive. so it is just a small distortion that can cause that pinger. >> the family members put to authorities trying to get answers, a lot of them were very sensible, basic questions that i was really surprised that authorities haven't released. i'm not even talking about to the media but to family members. how likely is it to happen? questions about like what sort of casing are the elts in, the electronic location transmitters? >> some basic questions, question 20, does malaysia have the capability to extract and analyze the black box information? if not, they're identified for the task. that is why i think the next meeting in beijing where the

authorities have said quite clearly they're going to bring in technical experts, i think if at that meeting they do not start to provide some hard answers, and i know mary has had much more experience of this sort of anger of families, when they don't -- when they turn up expecting answers. then the authorities will deserve all the wrath that befalls upon their head. on the question of the search areas and of all the things we talked about just now, what happens next? of course, they got the ocean shield. they got everything there in a hurry because of the 30-day deadline. they have done the searches that they needed to do within those parameters. but now if nothing is found they do have that little bit more luxury of time to do the sort of experiments that mary is talking about. to try and re-think things differently. because there is not a 30-day pinger limit about to expire. and they haven't found in the smallest, tightest area. so i think that is what we're

talking about when we talk about a re-appraisal of what happens next. >> i want to thank everybody on our panel tonight. up next with michael holmes. he will take us inside a lab with the technology that can unlock the secrets with the plane's black boxes if they're found. also ahead, the teen boy who flew from san jose to hawaii, what he told investigators about where he was actually trying to go when we continue. sfx: car unlock beep.

it has very good soundproving. >> inside the transplant safety bureau, the team forensical examine not just planes, but also ships. >> the reality is there are very few countries in the world, just a handful of them who have the technical know-how to work out what is inside one of these things. and this lab is one of those places. >> boxes from other investigations torn apart, burned, damaged in many ways suggests a top assignment. but here they say the story of what happened is usually found. >> a lot of our work is with undamaged recorders and it is very easy to download them. >> but even with really damaged ones, your success rate in getting the information off is good. >> yes, we've always been able to recover the information from the recorders we've seen. >> he is a measured, cautious man, pre rrequisites.

containing everything that neil campbell needs. >> in a box this big that is what you need. >> yes, that is the crucial element. >> it is highly possible that if they're found they will end up here where neil campbell says they're ready to tackle this situation like no other. >> and obviously the technology is advanced. but as much as the data and the voice recorders might tell what happened they might not tell why it happened, at least not overtally. >> that is right, it is a command from the pilot switch that was turned on, that switch then is not only noted that it was moved or that it was initiated but it also checks to make sure that intent, like for example, if you move the controls and it is supposed to move a number of degrees it will measure how much it moved. it is designed to see if it did

something mechanical. in that sense, if the auto pilot didn't function the way it was supposed to, is giving commands that were not received or given out, that would tell you what happened. but why it happened, that is something that takes a little more digging. >> and in terms of how long they can remain useful. if they're at the bottom of the ocean, can it be too long as long as the compartments are not compromised? >> yeah, as long as they're retracted from the ocean properly, in other words, kept under pressure, and properly rinsed under pressure, and then moved it could last indefinitely. years and years and years. >> so you have to keep them under the pressure that they're found in initially? >> you typically would, because of the fact if you bring them up too quick it changes the structure of some of the components, it can create

nitrogen bubbles, so you have to do it in a controlled environment to change the pressure. you have a box they can go into so you can bring it up by basket. but it is better that they get packaged in an ocean environment, and keep them packaged. up next, how the teenager who stowed away on the flight, and where he ended up. plus, stowing away on a wheel well is not impossible, roughly 200 people have beat the odds, their story is ahead. they're delicious, and an excellent source of fiber to help support regularity. wife: mmmm husband: these are good! marge: the tasty side of fiber. from phillips. you'd do that for me? really? yeah, i'd like that. who are you talking to? uh, it's jake from state farm. sounds like a really good deal. jake from state farm at three in the morning.

we understand that he told the fbi investigators that ultimately he wanted to go there to visit his mother. in fact, classmates from santa clara, california, said he told them he was from africa and that he wanted to move there. why he chose a hawaiian airliner, well, apparently it was the first plane he saw. but it gives you some insight in terms of his state of mind. we also gave you information on the time line, he apparently jumped the fence here at the airport at approximately 1:00 a.m. the flight left before 8:00 a.m., which means he would have been on the tarmac or wheel. approximately seven hours before it even took off, anderson. >> it raises a lot of questions about the airport security. the teenagers said they recognized the young man from the photos they saw of him. did they say anything else about him? >> that is right, they say this was an outfit he wore often at

school. he had been there only a few weeks. they say he was quiet, and very reserved. is what they say. >> and when you found out it was him, what did you think? >> i was really shocked, and just really glad he made it and he is all right. >> we wouldn't have assumed he would do this. the last person we expect. >> he never talked about going to the airport? >> no, that was a surprise. >> well, the boy right now is still in a maui hospital. they're watching him very closely but he is said to be okay. he is in the custody of child protective services. and ultimately at least at some point they will get him back to california. >> incredible story, dan simon, i was skeptical this was actually even possible. coming up, we'll show you how some famous stowaways have ended. also, yemen's conducting an investigation into the use of

force against militants. we'll tell you who by. ♪ ♪ no matter what kind of business you own, at&t business experts can help keep it running... seamlessly. so you can get back to what you love. when everyone and everything works together, business just sings.

we spoke before the break about how skeptical many are that a teenager was able to make it past the wheel well in a 767, it is not the first time it happened. in fact, people were known to survive in wheel wells.

a quarter of them survived. >> reporter: being a stowaway and a survivor means beating bone-chilling odds. a cuban defector did it in 2002 by hiding in the wheel well of a dc-10 that landed on the tarmac in montreal. he described it as being so cold he couldn't breathe. he eventually was granted the political asylum he risked his life for. he joins a rare group of just a couple of dozen people in the history of aviation known to have hitched a ride in the underbelly of airplanes and lived to tell us about it. in 2000, fidel maruhi was dazed by conscious after more than a seven-hour flight from tahiti to los angeles. but more than 3,000 have suffered the fate you would expect after being in a space

colder than a freezer for several hours with little oxygen. tisdale is thought to have breached security in atlanta and hidden in a wheel well in boston, as the plane landed, he fell to his death just as the landing gear deployed. >> this is a tragedy first and foremost for the tisdale family, secondly, it is something that once this occurs we want to make sure it never happens again. >> but for decades now, stowaways have been a rare but real problem. look at this life magazine photo from 1970, this 14-year-old drops out of the gear hold and falls to his death. and body parts fell from a wheel well in 2005 shortly before it landed in new york. a woman on the flight path describes how some of his

remains landed on her home. >> i noticed something that looked like a human or animal part. my first reaction was maybe it was a horse's leg. but there is a sneaker on the leg, it is a whole leg. the first officers on scene said oh, my god, this is a human leg. >> these graphic details make it all the more improbable that anyone would steal away on a jetliner and expect to survive. this california teenager is one of a very few to escape disaster, living on very little oxygen and a heck of a lot of luck. cnn, new york. still find it unbelievable. let's get caught up with some of the other stories we're following, susan hendricks has more. anderson, officials say there are examinations being done on bodies that was conducted with extensive help from american personnel. they're trying to determine if

the al-qaeda bombmaker, al-asiri was one of the ones killed. and pledging american support to keep ukraine as one united nation. he said the u.s. will never recognize what he called putin's illegal possession of crimea. the white house is giving $50 million in financial assistance. and they got a look at the mudslide area today. president obama promised residents that federal assistance will continue. and you have to see this. this is a massive iceberg, the white chunk you see that broke off antarctica last fall, it is moving quickly towards the ocean. this covers 255 square miles, almost twice the size of atlanta and six times the size of manhattan. scientists fear it could eventually threaten shipping lanes. >> that is crazy. it doesn't look that big from here, but obviously it is

deceiving. >> yeah, it really does, and six times the size of manhattan. and really, it is a waiting game and could take a year or so to finally disappear. they're watching that. >> susan, thank you very much. that does it for us, we'll see you for another edition of "ac360." cnn tonight starts now. good evening, i'm bill weir. thank you for joining us on "cnn tonight." day after day, the families of flight 370 have met with officials and demanded answers, tonight they are furious. tonight, i will talk to sarah bajc, her partner, philip wood, on board flight 370. she said it is like a bad comedy routine. we'll get a bluefin status report and examine the possibilities if the swimming robot keeps coming up em
