p.m. on cnn, and who doesn't want to watch a little tiny cat drinking out of a three-inch bottle. doesn't get cuter than that. all right, thank you for joining us. we'll see you back here on monday night, 7:00 eastern, anderson cooper "ac360" starts right now. good evening. 8:00 p.m. here, 8:00 a.m. in the search for flight 370. there is word that the flight search has been expected to move. in addition, new theories about what happened, shark reacti sha what happened to it. and all the angles ahead. also, take a look. this is happening to more and more children, rare childhood diseases, preventible ones that could do much more worse things that raise a rash. we begin with breaking news at a crucial phase in the search for flight 370.

the single bluefin-21 sonar scanner has now covered about 95% of the area the investigators have called the most likely possible resting place for the boeing triple 7. when it is done we're just learning where the next focus position may be. remember, bluefins have been on more than a dozen missions. it has yet to find anything. we have yet to see anything, not one single image from the robot sub. and flight 370 took off with 390 people on board. several satellite connections and a handful of possible sonar pings, there were no signs of the airliner. the answers will come. this is for now the longest running aviation mystery of our time. tonight, we'll look at some of the new approaches that investigators may find. first, miguel marquez in perth, australia. the bluefin has nearly completed the first phase of the entire area, focused around the

strongest ping they detected. what is the latest sign? >> no sign of the plane. at this point it is probably very likely that the bluefin has completed that mission 13 and probably covered 113% of the area. what the -- authorities here are saying now is that they will continue to search the adjacent areas with bluefin to that pinger number one location to see if there is anything they can pick up around it. and then as we understand they will pick everything up and move six miles north at some point. whether they can do that with the bluefin or some other technology that they will have to employ is yet to be seen, anderson. >> and moving north because that is where another ping had been heard, correct? >> this was the first ping that was heard. it was a very long sort of ping. a very good quality. they got four in total. two of them were not so great. two of them were very good. they started with the best, strongest signal. they're going now to the second best strongest signal.

it could be somewhere in between those two. but this is the best that they have right now. o and it is hoped that it will be found somewhere around that first ping, anderson? >> all right, thank you, it is not a mystery or the logistical puzzle, it is the fate of a daughter, lost one or friend, a father. and indeed, the family members say they're getting a steady dose of evasion and mixed messages. yesterday, cnn comprehend richard quest took their answers right for the top. sitting down with malaysia's prime minister. and some argue they will get the same. >> prime minister, are you prepared to say that the plane and its passengers are lost? >> at some point in time i would be.

but right now i think i need to take into consideration the feelings of the next of kin. and some say they're not willing to accept it until they find hard evidence. >> well, that was yesterday. a month ago he said the opposite. listen. >> it is therefore with deep sadness and regret know -- that i must inform you according to this new data, mh-370 ended in the southern indian ocean. >> joining us now is steve wang whose mother was on flight 370. steve, thank you for joining us. i am sorry it is under those circumstances. i can only imagine how frustrated you are at this point. how are you holding up? >> well, we'll finally find our family, our loved ones, no

matter how long it will be. we'll keep up. >> you have been searching for answ answers, getting none from malaysian officials. our reporter from kuala lumpur, he asked about the questions. >> i know this is a very, very excruciatingly painful time for the family members, i understand that. and we did our best. we did many, many briefings and we gave them as much information as we could in terms of information that could be -- that was corroborated. but the most important information that they want and sadly the one that we cannot provide is where is the plane? >> do you accept that answer? >> well, it tells me nothing. we are asking technical

questions and this month in kuala lumpur in beijing we were asking questions about inmarsat. but they never gave such information to us. what we asked for, there was records from the tower of the the plane a they didn't provide. they asked about radar, they didn't provide it. the kind of information, they have already provided it to us. and what we want to do is to ask for inmarsat to help us confirm whether they are searching the right place or not. and it is very -- unfortunately, they, the militia government -- it is messed up, asking technical questions, not facing the fact. we are asking questions to help them find the plane. but they said stop it and move on to the next step. they act as though they have some certification or something like that, that is really terrible for the family members. >> i saw some of the questions,

they are good rational questions about the locater transmitters about what kind of box they're stored in. they're very realistic, technical questions. i was stunned to learn the family members had not been given up to this point. those are answers that could easily be given to family members. >> yes, so that is the point. we asked only technical questions. it is not about mh-370. but it is about the plane. the triple 7. about the system, how it works. but they still refused to give us the answer. i don't know what kind of good communications that they are providing to the family members. >> are you prepared -- at this point it has been seven weeks. are you prepared for the possibility they may never find this plane. but are you convinced they will find this. just a question of how long? >> well, with the high tech technology, i think i am very confident that the plane will be found. but it will take a long time, but it will finally be found.

>> steve wang, i'm so sorry that all you're going through. and my best to your family. >> thank you. and turning to the panelists, author, david souci, also analyst david gallo, director of special investigations, and richard, the families are frustrated. what has been the reaction to your interview. you were able to get the prime minister to promise to release the investigation's preliminary report. but it is really no secret that the government there is not used to that find of transparency. >> i think the reaction from the families was in some ways predictable. they don't believe the prime minister will keep good on his promise. and even if he does release the report they are still convinced that something will be left out. something will be hidden. the families really fall into several categories and we really can't lump them all into one group.

there were those who in some ways have come to terms with it. they have a dignified silence and are getting ready to go into the next part of the process. there are those who want answers, what actually happened and what can the government and airline tell us? and then there are those who simply believe the plane is wait ing to be found. diego garcia, kandahar, wherever you like. but the entire range of the families comes down to the same view that they still don't believe the government is providi providing enough information. >> and david souci, we hear the plane is moving elsewhere to search, you think that should have been that way all along. why? >> to me that ping reception would give them much more information. but i suspect through a couple of sources i talked to that that area is much deeper.

so i think they kind of worked under where they thought they could work. and it was a good chance. it was in the center of all pings where they started. but they're going to have much better luck once they get deeper equipment where it could work and go up to the first ping. >> and david gallo, it seems as though it turned up nothing. has it been a waste of time or is that a fair criticism? >> i don't know, anderson, i don't think it has been a waste of time. knowing where the plane is not. that is important information. too. as long as they're confident that they have not missed it, it is up to the analysts to decide. the next bit is a problem. if they go too far to the north it will get quickly deeper and more rugged. >> and david gallo, can we be confident when they say they found nothing, is there a chance that it missed something? >> you know, they have been going low and slow, just that if there is anything there that is not natural that it would pop up

on that screen. but that is all going to depend on the abilities of the operators. and that is a tried and true team. so i think that they have that pretty well covered. >> richard, a lot is obviously riding on the radar provided by the malaysians, using the inmarsat data that helped them come up with the search off australia, is that radar data something that should be re-examined? >> the radar data from the malaysian military is pretty uncontroversial. it is blips showing the plane flying across the country and then going out west. but what it does show and i have on very good sources, it does not show it flying way points. it does not show some carefully constructed route west. it is a straight line west that happens to hit several way points. now, that takes us up to about 2:20 in the morning. and that is the last known position. if the inmarsat satellite

handshakes fails on accuracy you're back to that position. you really are back to the very beginning of where the mystery begins. and once you're there, frankly, you are calling into question the corridors, you're calling into question the inmarsat and ultimately the radar data. >> david souci, i talked to david gallo about this a couple of days ago about the human search, is there data that nothing has been found, that momentum for the search will somehow be lost? >> well, i think just the energy level at this point regardless of whether they found or didn't find anything, there has to be times when you take breaks from this. most of my investigations has been on land. i've seen the same thing on investigation teams. you just run out. at some point you have to escape that because you start to draw incorrect conclusions. and the investigation can go quite awry if you don't take

time to reorganize, to rethink and to get some sleep. to get some food or bring fresh eyes in to evaluate your own team to see are we on track or are we inventing something to go down the wrong path? >> david, you have been out there on the water on air france flight 447, do you agree with david souci on that? >> yeah, i agree with david completely on that. and they're going to get that break, anderson, because one, the ship has been out there. after about four weeks at sea you really need to get into port and re-energize, but also to get a whole new set of tools to that area in perth is going to take some weeks. plans have to be drawn up. so i think we're looking at at least a couple of weeks of down time unless there is something out there that i don't know about. that will get out there on the site and go that deep. >> interesting, a lot to cover tonight. first, remember that you can set your dvrs so you can see

episodes of cnn. and coming up, how they stand up to the evidence. some of them of fantastic. later, the aviation mysteries even more than half a century later. beyond amelia earhardt, there is a lot more we don't know about. ameriprise asked people a simple question: in retirement, will you outlive your money? uhhh. no, that can't happen. that's the thing, you don't know how long it has to last. everyone has retirement questions. so ameriprise created the exclusive.. confident retirement approach. now you and your ameripise advisor can get the real answers you need. well, knowing gives you confidence. start building your confident retirement today. at your ford dealer think? they think about tires.

the breaking news tonight, a u.s. navy source telling us about what could be the next big move in the search for flight 370. a shift slightly to the north of the circle around where the first ping was found a week ago. we talk a lot about this absence of hard evidence, debris or sonar. it doesn't necessarily mean that anybody is doing anything wrong or that their strategy is somehow unsound. it does, however, create a vacuum on the alternative theories, some of which are implausible, and some just downright unbelievable. >> reporter: conspiracy theorists have a bundle of theories, one, that aliens stole the people on flight 370. >> or the terrible thing that is happening is attributable to aliens is impossible.

>> reporter: he says people are drawn to mystery and suspicion. especially when feelings of fear, anger, and grief are involved. as is the case with the malaysian airliner. on social media, conspiracy theories about the missing plane are still going viral. this tweet pretty much covers it from time travel to an invisible cloak for the airplane. others wonder was the plane hijacked to afghanistan? or did it land on the u.s. military base known as diego garcia? the island in the indian ocean has restricted security clearance. but that has only amped up conspiracy theorists, so much so that it found its way into the white house briefing room. >> some reports say that the flight could have landed in the u.s. military base, diego garcia, in the center of the indian ocean? do you rule that in or out? >> i'll rule that one out.

>> reporter: another conspiracy, an outrageous insurance scam. the malaysian police chief gave that theory legs. listen. >> shouldn't it be somebody there on the flight that -- who bought huge sums of insurance who wants the family to gain from it? or somebody who has so much money -- >> if not that, then perhaps some suggest north korea took the airplane. >> the notion that north korea would choose to exercise such authority and capacities as it has to hijack this plane, that seems in the realm of desperate speculation, too. >> of course not all theories are as implausible as some of those. others are more believable, pilot suicide has not been ruled out as well as rapid decompression, with the plane running out of fuel. another reasonable theory? fire from lithium batteries that

brought the plane don't or a real cargo problem that caused the plane to crash into the sea. >> others that have happened in history are probably a good start, and to have technical explanations, that is a little more solid. >> reporter: more solid, but still no concrete explanation and no plane. randi kaye, cnn, new york. back now with richard quest and jonathan kaye, we're hearing extensively about the conspiracy theories. jonathan, it is really fascinating to me. these theories that persist around things that we find terrifying, and certainly flying falls into that category. >> sure, you know, even in normal times people are absolutely terrified in many cases about boarding an aircraft. our brains tell us statistically

it is quite safe, but being 30 feet above the earth our imaginations go crazy, we think about the people sitting around us and terrorism and all sorts of things. and it is only natural that this kind of material would be ripe fodder for conspiracy theorists. >> and you know that we hear a lot of them, richard, people tweet them to me, as well. the fact the authorities are not as transparent or as forthcoming as they could be in the investigation certainly adds to these theories. >> i am not sure, i would go with that, anderson, for the simple reason that the sort of conspiracy theories we're talking about come because there are not any facts to discuss. and so it is not as if -- the sort of issues that have not been revealed don't feed conspiracy theories. i'll give you an example of just how wild this has all become. yes, it is well known, the fact

that i filmed with the first officer, fariq hamid, about two weeks before the flight incident with flight 370. pure coincidence, but there is no shortage of suggestions that cnn had something to do with it, know more about this, on and on it goes. so what i'm saying, flying is such a loss of control, therefore conspiracies will abound. >> and jonathan, i also find it interesting that some family members have latched on to these theories. is that something you see in the wake of tragedies where again, they don't have an answer? >> it is, and it happened after 9/11. you had all sorts of 9/11 conspiracy theories. one of the reasons for this is that anger and suspicions sometimes are easier emotions to

control than sadness. if you're angry at someone, if you feel there is a political aspect to the emotion you're feeling at least you can direct that in an outward way. you can do something about it. agitate for something. sometimes that is an easier emotion to manage than being sad because you lost a loved one. >> john, you said that air travel may be a conspiracy. >> one of the odd things about air travel is that pilots can turn off the transponders in the aircraft. that is one of the first things that the 9/11 hijackers did for instance, and one of the questions about the flight 370. and manufacturers may take away the ability for pilots to turn off transponders. there actually is really no good reason why we shouldn't be able to track these aircraft at all times. so it would be interesting if in my mind that were a positive policy change that would come out of this incident.

>> all right, for more you can go to cnn.com. coming up, what if flight 370 was never found? hard to believe that could happen, but it would not be the first time in history that a plane has disappeared. obviously it goes beyond amelia earhardt. also ahead, the korean ferry disaster and more people found. the latest in the investigation coming up. if you wear a denture, touch it with your tongue.

current search area, a new target will be in the north. one demonstration was how a passenger plane could simply disappear. it seems like that would be impossible. there are other times that planes disappear. kyung lah reports. >> reporter: frustration mounts as the search continues for mh-370. but look back through aviation history and there are other mysteries that linger for months, years, even decades. >> there have been planes in the past that have completely disappeared. >> reporter: carol gray is an aviation historian, he says that amelia earhardt vanished as she attempted to fly around the globe. >> there is still no concrete evidence as to what happened. >> her mystery unsolved. for a passenger plane like that

to disappear, that is not unprecedented either. >> no, and one that comes to mind is the british south american airways. >> two british south american airways jets disappeared in the infamous bermuda triangles in the '40s. also the bomber mission, with the plane vanishing, even the search plane went missing all without a trace and still unsolved. then there is this. the flying tiger. >> and it went off near guam, the flying tiger line went off the radar, gone, disappeared. >> no wreckage? >> no. >> reporter: it was 1962, a u.s. military flight with more than 90 people on board, unsolved. the crash of the uruguan flight was so mysterious that hollywood depicted the tale in the movie "alive." the passengers crashed in the andes mountains.

the death toll is rising from south korea's ferry disaster as divers continue to recover bodies from the sunken vessel. 187 people are confirmed dead, many of them high school students. president obama arrived to the scene, and said as a parent he can't imagine what the people are going through. he gave the south korean president an american flag along with his condolences. >> this flag was flown over the white house the same day as the sinking of the sewol. and in that spirit i'm presenting this american flag to you and the people of the republic of korea on behalf of the american people. it reflects our deep condolences. but also our solidarity with you during this difficult time and our great pride in calling you an ally and a friend. >> the ferry captain, 14 other crew members have been arrested as investigators try to piece together what happened to cause the disaster. kyung lah joins me now from

south korea with the latest. you're just outside the search area, what is the latest going on right now? >> reporter: well, as we speak, anderson, divers are desperately trying to reach an area of the vessel, one room where they believe 50 girls may have huddled together as the waters were rising inside the vessel. they did find another room with 48 girls. they pulled those out. that is a second room where they believe there may be more girls. they're trying to access as much of this vessel as possible today because the weather is expected to turn in about 12 hours or so korea time. it will make it much more difficult. we're already hearing from divers that currents are cutting off their breathing tubes. they're in a mass of floating objects, so they're trying to get to as much of the ship as possible. they're asking fishermen to keep an eye out for anything that may be drifting, anderson? >> i'm just describing the room for all the young girls, just

imagine what it is like for divers to come upon that in the darkness with low visibility. it just has to be so traumatic. are authorities closer to find out in terms of the investigation what caused this to happen? >> reporter: at this point, prosecutors have been very firm that this will take months to come to any sort of conclusion. a definitive conclusion. they are drilling down, though, on two very strong possibilities. that the cargo may not have been tied down properly. and that some renovations made to the sewol last year adding cabins to the upper part of the ship may have affected the balance and it may have been easier for the ship to have capsized. so they are looking into the investigation. >> and i understand that with the shift of the vessel -- >> reporter: you're talking about a sister ship. the important thing to note here is that the sister ship is owned

by the very same company. this gives you a picture of this company. in this sister ship there were a number of violations, safety violations that were fund by inspectors. there were 40 life rafts that didn't work. the emergency slides didn't work. as far as tying down cars, because this is a ferry that did take cars back and forth, those ties didn't work. the containers, yes, they had ties but they did not work very well. so we're getting a picture into this company, anderson, and whether or not safety was even on its map. anderson? >> wow, kyung lah, i appreciate the update. joining us now, jim staples, maritime security analyst. captain staples, you just heard from kyung lah talking about the safety issues with the sister vessel. how big a concern are those assets that she just mentioned, cargo not tied down well, the

ship not working well. >> this is an amazing concern, anderson, when you see that the sister ship is having problems with the safety, the life rafts and equipment we probably will most likely find that the same conditions existed on the sewol. so we need to go back to find out if the company even bred a culture of safety with the management, a culture that operated within the two ships. so this is a ship that has primarily the same problems. >> and just as you said captain staples, the investigators are looking into whether or not cargo shifted on the ship. you have been a captain on this type of ship before. it is critical for every piece of cargo to be latched down. explain why that is so critical. >> yes, anderson, it is very critical. as we see, when a vessel takes a sharp turn or an easy turn, depending on what her stability is, we do not want that cargo to shift. because what we have is a shift in the center of gravity, which can most likely move in an

upward direction. this causes the vessel to become very top heavy in the rollover and not be able to come back to the stable condition. what we call it is a riding arm in the stability. and this is of great concern when there is a not very good riding arm. so making sure the cargo is latched is a priority on every vessel, from container ships to cargo vessels. this is one of the main functions of the crew to make sure that this is latched down. so this is of great concern to the ship. >> and kyung, this was added to the ship, passenger cabins, some say it could have been too top heavy. what do you make of that? or would they make adjustments to any additions? >> well, in fact, the organization that is responsible for that, before they would allow the additional cabin space to be built because it changed the metacentric height of the vessel, they stipulated that the

owner of the sewol would have to increase the amount of water ballast so that they could stabilize the vessel. and also they had to reduce the amount of cargos and containers. what they have to look into is whether or not the changes were ever made. >> and captain, they found out the crew had not received safety training. as a captain is that just shocking to you? i mean, that would seem to be kind of the basic thing that a crew should do. >> well, you said it right. it is a very basic thing. the basics of the basics. training and security is the training we have to do on ships. everybody has to live in a safety culture to make sure we don't have these types of situations. so absolutely correct. it is astounding to me that in an environment like this, in a maritime country where they have a great ship-building capacity would even have people that don't train their people in safety. it just amazes me. i'm shocked and i'm surprised.

>> kyung, i understand you have been in touch with some of the rescuers. i can't imagine, again, i come back to what it must be like for these divers working under these conditions, coming upon these kids, these children who have been in this ship now for more than a week. >> anderson, it is absolutely horrific. and as more information is being revealed we're starting to see that there has been a fatal chain of predictable errors. we had failures in leadership, in training. in equipment. and now we're starting to look at design and government oversight. and that is why the investigators first began with the captain, next, the crew. then it was the company, then the owner. and now we understand that the very agency that is responsible for oversight of the shipping industry has had its executives barred from travel out of the country because of what one investigator who was involved with the government said is a look at malpractice and potential corruption throughout

the shipping industry in korea. this is really shocking. >> wow, it has gone further than this one vessel. i appreciate your time,. up next, an outbreak of measles, what is behind the outbreak and what is done to contain it. plus, details about what a 24-year-old american tourist did just before he was detained at customs in north korea. in the nation, we reward safe driving.

metacent tonight, u.s. health officials warn about a disturbing surge in measles. 129 people have been affected in 13 states so far this year. that is the most in the first four months of any year since 1996. california is being hit hardest, measles is highly contagious. it has a new foot hold now. >> this is a highly infectious disease. >> reporter: it may start with a fever or a cough. but a splochy red rash is its signature. >> you're infected four days before you develop symptoms so you may not know you're sick. >> reporter: many people in the united states have never seen measles since it has been gone

over a decade ago. >> i knew what to look for. the new physicians have not been used to it. so part of the public campaign is to make sure they know what to look for. >> reporter: in california, the number of cases has risen in the past couple of years, so far this year, 58, in orange county, california, the number of cases has gone up. >> we had 22 cases here in orange county. that is a lot more than we normally have. we had over the past five years, no more than one or two cases a year. >> why the sudden outburst? the number of parents refusing to vaccinate their children. last year, many opted out of sh shots. is there any reason to report that vaccinations could be dangerous to children? >> absolutely not, there are serious consequences to getting the measles. >> reporter: so here, they're trying to spread the word faster than the virus that the vaccinations work.

>> the two shots that you get is almost 95 to 98% protected. >> there have been no new cases here in three weeks, and more people are getting their shots. maria brought her children in for their shots two days a after hearing about this outbreak. >> education can overcome the misperceptions. >> reporter: another reason for the outbreak is our shrinking world. according to the center for disease control, 93 people contracted the measles from and bro -- overseas. the doctor says the majority of people opting out of vaccinations are in the more affluent parts of orange county but he hopes through education their minds will be changed. stephanie elam, cnn, orange county, california. and again, it was all but wiped out in the country and now

it is back. sanjay, more people in the united states were infected with measles than in the past 18 years, why the increase? >> you know, i think there are two things happening here. as you know, anderson, i just returned from africa covering the ebola story. and one of the things it reminds you are, we live in a very global world where these pathogens can move around the world faster than ever before. and what is happening, much of these cases came from overseas to begin with. 17 from the philippines. but the other thing here is, something we talked about a lot you have increasingly these pockets of people not getting vaccinated. and that is a real problem, it is a very contagious disease. and if somebody comes from another country it could spread very quickly in these pockets. >> you're a doctor, have you seen the spread of measles? >> you and i have seen the

spread of measles but it was in africa. back when we worked on the documentary years ago, as a doctor in the united states i have not seen a patient with measles. we have made really good progress. but in other cases you still see cases. in fact, take a look at the map. anderson, you can get an idea of what it looks like around the world. those places where you see the highest number of cases, the most cases, they are not surprisingly the places where the vaccinations are the lowest. >> it starts off in many ways as a viral illness. people get the fatigue, the headache. the muscle aches, what is characteristic of the measles, you get this characteristic rash around your body. this sort of almost pinpoint rash. it can also arriving your eyes. those are some of the outward symptoms. where it can get really scary

and out of control is where you develop infections of the lung and brain. and even for people who recover after an infection of the lungs and brain it can be debilitating. >> even if you get the vaccine as a child, it is effective? >> adults that got a shot after 1956, it may be worthwhile to make sure you're still immunized. they can do a blood test to determine that. but if you look at childhood vaccination programs just over the last 20 years they have prevented some 300 million illnesses in this country. 300 million. close to a million deaths prevented. we talk so much about the fact that we treat disease after it occurs. everybody gives a lot of lip speak to prevention, they have the data to show that. >> and also saving billions in health care costs. bottom line, you get your kids
