although a little bit of good news. the rate at which they're going up appears to have slowed down a bit. it will still be a month and a half before we know if the outbreak is over. >> sanjay gupta risking his life to bring us that important information. newsroom with brooke baldwin starts right now. >> the first time they sent down the blue fin, they hit a depth limit. second time came to an abrupt

end. twice begs the question, how long is this going to take? 16 feet long, has to map a section roughly 230 square miles. here is a comparison for you. chicago, hidden deep under water. the search area, roughly the size of america's third largest city. it's an area that will take months to scan and that is without these hiccups. why not throw more of these pieces of technology at this? why not more blue fins to be used and is this the right device for the job? the mothers, the fathers, the aunts the uncles, increasingly agonizing.

. anger is boiling over. >> to show that this particular format with results, so we have decided to leave. >> there they go. they say there have been too many lives, what are they hoping? that third time's a charge? >> they are hoping this will turn out to be a full 16 hour scan. we had the technical glitch and the problems with the water being too deep. we are asking the same questions. what's going on with the blue fin. are they going to be additional resources brought in to help speed up this process? i asked the search chief that

very question on monday. there is nothing else anywhere close and therefore we have to make due with this piece of equipment. but when you see these hiccups and that we don't know yet what the jury is still out on the third one you have to wonder how long is this going take and is this the right tool? >> we're going to ask questions with regard to the one single blue fin. what about the oil slick? tell me about that. >> they found this oil slick near the area where the last ping was detected and they took a two liter sample, which was sea water mixed with whatever substance it was. that sample was brought by an australian ship to an aircraft that landed here in australia. as far as we know it's being

delivered to a lab or it is at a lab where analysis could come relatively soon. we were told this might turn around regulartively quickly. is this a substance that would possibly be leaking from that boeing 777. that's something that we're deaf ni -- definitely monitoring. >> let's focus on the blue fin 21. >> joining me to talk to us about this are two gentlemen. welcome. richard, if i may, i would like to begin with you, reading what you told our producers. you have experience working with the blue fin, specifically, searching for the emili

emilia earhardt wreckage. >> it didn't work for us. we were very hopeful that the blue fin 21 would be the answer to search to find wreckage. what we found that it could not perform reliably. we had extremely frustrating aborted missions. and technical issues it was just not fun. >> okay. so i hear your frustration. >> what else could they be using? they are all the fashion.

>> but in this particular case, they might want to consider and i'm not an undersea search expert. i just know what doesn't work or didn't work for us. but towed array sonar, it's an older technology. you use the same sonar but instead of sending it off in a fish on a programmed mission and that's a very complicated thing to do, you simply tow the thing behind a boat at the specified distan distance. >> jeff, i want you to chime in.

>> you use three to find the wreckage. tell me why they're just using one blue fin here? >> they are only using one because that's all that they have available. you wonder if more authorities had exerted more preshire. it's not that there is one or two kinds of auvs, there are all sorts of kinds i do know that the smash operating just under the limit that it is designed to do. it would be easy for this other auv to do this kind of work where the blue fin is really almost not appropriate for this job. >> there is one school of thought. maybe this is the more

optimistic ignorant school of thoug thought. >> i'm just trying to read into what the authorities are doing. you could say, they must be so confident that these pings on the other hand, i would point out that remember, they spent six days going pingless, waiting, hoping that the towed pinger locator would detect m e more, and obviously they weren't satisfied or they wouldn't have waited so long. the fact that they talking about a huge area is a big clue.

and not false positives, you would think they would have narrowed it down to a farly exact area. >> thank you so much for your expertise. we will have you back on in the hour. we will toss a couple of questions to you in a little while. this is bringing fresh supplies to investigators. we will take you on it. don't miss that. suspicious activity along the boston marathon route. have you seen this video?

are still ships close to the ship that zung itself. they are trying desperately to see if there are any survivors. there has been some anger from parents here. some scuffles suggesting that enough is not being done. they don't believe that the search and rescue is being handled. with such pressure and desperation, there will be these kinds of scenes. there are survivors still on the ship. they have no phone or internet connect. to get help and tell people they are still alive. it's not clear whether that is a tech message that has come

since its first hit the so called auv has cut short its 16 hour seabed mapping missions twice now. today an unspecified technical issue forced it to the surface. its data was downloaded and results were nothing resumabling a plane or a black box. the hopes of finding this were told that the visual search for the debris field then there is this side of the story. passengers are only seen. these passengers are mostly

chinese. attorneys startle circling years ago. american courts may be more likely to toss out some linked to the investigation. nice to have you back. >> how are you? >> i'm well but these families, here's the issue with u.s. courts. what are the chances that the passengers could sue boeing claiming that the manufacturer was somehow responsible. >> to bring the case against the airline, the montreal convention applies.

the principle place of business would be malaysia, your final destination. for the families of the chinese victims it's going to be very heart even if the case is brought in the united states to sue malaysia airlines. >> if a part of the airplane is ifrly kated in this accident sequence, then they could bring a products liability action in the united states against boeing against component and system manufacturers. now even if that's brought, there is still another doctrine in the united states called format convenience where the courts have the authority and power to say the united states is still not the most convenient forum and the case should still be brought overseas. if there is a component

malfunction to bring products liability, for the case against the airlines if you're chinese, you're going to have your work cut out for you to keep it here. >> okay. we do know that at least here in our american courts with jury systems that the juries are very sympathetic to air crash victims, whant malaysia's justice system? >> well, they're going to have their work cut out for them. >> a lot of people do, it sounds like. >> the malaysian government, their system of democracy is a far cry from what we're used to in the united states. they have a two tiered court system. it will be very difficult to get full and fair compensation against malaysian authorities, malaysian airlines in malaysia.

>> what's the best bet, taking the route or just hopefully settling? >> let me answer it this way. >> you're on the hook for $170,000, 100,000 sup limital drawing rights. pay it out to these families now. you have wage earners living in these hotels. you're going to have to pay it out. >> that's it? i can hear some families saying that's it? >> that is a payment that would be made without fault. the second phase of this, it's a two-tier system of recovery. if you can show negligence, which i don't think there will be any question that i think we can do, then they are entitled

to full and fair compensation certainly that means if it were in the united states you're talking very substantial dollars. it might be better but it's certainly not going to be what they would get here. >> okay. as always, thank you. >> thank you so much. >> when we're talking about the families, anger, rage, they're upset but it continues to boil over. watch this. here they are, once again, storming out of a meeting. we'll tell you what specifically made them angry this time. and ukraine. on the brink of civil war. that is a warning coming from russia's president. we will talk about how serious this situation is becoming.

>> welcome back. you're watching cnn. i'm brook baldwin. military combat vehicles, russian flags make their allegiance alarmingly clear. no one is saying whose army this is. even more unnerving, these fighters and their supporters rubbed up today to reassert authority and their supporters. so at this hour it is a potential tinderbox, very, very confusing. but we do know this. it will not allow harm to come to pro russian ukrainians while ukraine, nato and now the ukraine say no resists but the

russians are stirring things up a bit. the u.s. led alliance today has announced it is stepping up patrols immediately along its eastern border. keep in mind the russian have troops on the other side of the ukraine. so, is nato finally drawing some kind of line here? >> nato is desperate how to deter putin from making any other land grabs you may have word several words bandied around. i spoke to the russian eu ambassador today and i pressed him on are we going to see any more land incursions by the russian military? and he said absolutely not.

what they do want is, as i have been saying, some kind of pressure maintained on the authorities, that is what they're doing ahead of the four-way talks that will start in europe, in geneva tomorrow between the united states, europe, russia and ukraine. hoping to form a political solution. >> so he says no. on the flip side you have the west. there is this other sign the west is ramping up because the head of the cia, john brennan, he made a quiet trip to the ukraine over the weekend. might he help keep the russians at bay? >> it's really odd that the white house confirmed his trip. as we know the white house and other nations have ruled out any kind of military help to the ukrainian authorities, thould

they be trying to help ukraine figure out what's going on? would it be about sharing intelligence or figuring out how to deter any more russian disturbances in the eastern part of the country? i really don't know. but obviously russia has jumped all over this trip as some sort of conspiracy theory. independent observers including a human rights investigation on the ground has conclude d the disturbances are entirely racked up helping them inside the eastern ukraine and the u.n. has said there are no significant instance instances and that there may have been some issues of. >>ment but none to the extend

that russia is claiming. massive russian propaganda. they are spouting the kremlin line. there are a lot of lies and misrepresentation. news organizations are pretty much the only information that people are getting which is troubling. maybe i am going on too long but an interesting new poll has come out on the ground after the crimea referendum that shows that a majority of ukrainians are -- they want closer ties with the eu and the majority saying they don't feel under any threat or pressure from ukrainian authorities at all. >> thank you, thank you, thank you. >> coming up next, back to our special coverage. the families that passengers lost in the planes.

>> day 41 of the search, families of flight 370 are

continuing to press for answers to a host of questions. we will actually take some of their more technical questions to our panel of experts but first let's go to ivan watson. >> anger and rage from families of passengers of missing malaysian air flight 370. >> officials in malaysia were supposed to hold a conference on tuesday with relatives of some of the 153 missing chinese nationals but technical glitches blocked the link. >> an interpret eer translated

angry pro testers stormed out of the room. some hurling abuse at mute officials. lack of information about the plane has bred suspicious here. >> people were yelling liars at the screen, at the malaysian authorities. >> they are liars. >> steven wang's mother was a passenger aboard the missing flight. he's one of hundreds camped out at these beijing hotel waiting desperately for news about missing loved ones. >> it is like a cage full of bad emotion, we feel sad and lonely and exhausting. >> for more than a month, malaysian air has been accommodating the families of more than 100 passengers of several hotels in beijing. it has been an agonizing vigil.

>> the sessions feel like a cross-examination. relatives ask often times technical questions, questions that these men simply cannot answer. it is an unhappy desperate increasingly angry situation. >> 26 questions in total surfaced today on a chinese social media website. families are demanding logbooks, recordings of conversations, cereal numbers for the black boxes and very specific items when it comes to maintenance

records. let's talk about what they are demanding. before we get into the more kek any call questions, obviously these families are frustrating, but what are their rights at this point? are they entitled to this? >> no, traditionally, an aircraft investigation, the authorities will gather information and not release anything until there is a preliminary report and sometime after, a year or more in many cases, then a final report would be issued. and only then would the material be made available. in this case malaysia has bent the rules. as you are recall they released a full transcript of the conversation between the flight crew and air traffic controllers, that was something that they didn't have to do and

more recently the aking transpor -- releasing that information which is very unusual. clearly they are feeling a lot of pressure to open up. >> yes, the world wants really the information for the black boxes because that holds the key to what happened on board this plane. my question to you is these families don't just want the black box information but they want the cereal numbers to the black boxes. and you asked the question yourself. why not more assets being deployed? and i can give you a peak behind the curtain.

i happen to know the answer to that. we're often told the search is often described as a u.s. navy operation, the blue fin 21. it's not. the u.s. navy wants to help. they don't have search and recovery assets itself. it outsources that to a contractor. they have one blue fin 21 that they bought. it's a reconditioned unit. they bought this in the spring of 2012 just before our search. that's why there is only one blue fin 21 because the contractor only has one bluefin 21. is it the right technology or the contractor? i think these questions need to be asked.

>> we're asking them today. i imagine the families are saying throw as much resources as you can as possible. thank you so much. coming up we will take you live on a ship to see the challenges that investigators are facing. how the underwater landscape could mean that sonar technology that they're using is wrong. starts with back pain... s ly ...and a choice. take 4 advil in a day which is 2 aleve... ...for all day relief. "start your engines"

>> you know those five dollar words we all wrote on flash cards and we studied so much before the test to get into college?

here is one for you. propen queuety. or -- those are several words that will not be on the list any longer. to sum it up, studying for the sat is becoming, unlike when we did it, less intense. >> and we roll on. you're watching thmpb ining cnn. we have learned that searchers

will abandon the search for floating debris. it will hinge entirely on the blue fin 21. not just once but two times. the first time it hit its depth limit. the second, resurfacing because of a technical issue. they did download some of the data and analyzed it once again. nothing found. so the wait, the lack of any information causing more frustration for the familyies fr the passengers on that plane. >> these are pictures of a video conference briefing with malaysian airlines, you hear the

shouting. this was delayed. these fed up families, you see them here? they stormed out of this briefing. what are the challenges here? earlier the head said the sonar device will help move the searchers step further but he stopped short of pinning all hopes on the suv. >> i would caution you that the deployment will result in the detection of aircraft wreckage. however, this is the best lead we have and it must be pursued vigorously. >> she is back on a boat for this live demonstration of the sonar technology. so as we talk about the auvs, and we talk about sonar, that's

like taking pictures with sound. kind of. >> exactly. how sonar worked in the incredible depths that we cannot imagine. your devices are being used in the search how does sonar work? >> sonar comes in all shapes and siss. this is a 2125. side scan sonar is a different type. but the fundamental principles are all the same. going to emit sound, bounce off of the sea floor and it will interpret it in temples of an image. >> they have had trouble so far going into the water with these unmanned vehicles trying to take the sonar down and see the images. how difficult are the conditions? >> it's incredibly difficult.

there's more to the sonar than in this whole process. that unmanned vehicle has to have navigation systems. all of those systems have to work together. >> so let's take a look and you get that data. in the process of what you get from the sonar. >> we have been mapping throughout the day here. they're going set up a grid pattern and they're going to move that grid pattern and that's what you see here. we're now at this point and building up additional mapping information. this is going to construct the map. we're going see this live. we have gps. they don't find this until the

vehicle comes back. >> and with the side scan sonar, how difficult is it to get clear resolution? >> it's an excellent system and it's really good in deep water. >> you're putting sound out to the side and it travels through the water, hits the sea floor and goes out and you build up an image. here in the shallow water we get reflections from the surface. the image is a little more clouded. it's very, very clear. >> that's surprising to me. you would think that would make it worse. >> it's a nice stable vehicle. there is no other sources. so it generates a very nice language. >> here is one thing. because they're going down and they don't know what the sea floor looks like in this part of the ocean, they have to go down and see what they could get so

it takes a really long time to get this information. >> do we know? maybe feeling optimistic. what would the picture look like if they do see wreckage? >> what would the picture look like? would you know? >> it's like a photo. you're going be able to discern what it is if it's large. you may just be able to tell that there is an object. but large on jeks will come out very clear. >> is it that deep down in the ocean? do they start getting covered up by the sea floor? >> there is not a lot of oceanic processes happening that deep. there's a chance that it buried when it hit the sea floor. >> that's about it it's a lot of unknowns. >> okay. okay. thank you so much. and right now the underwater

search involves the blue fin 21. this unmanned underwater vehicle. >> and showing how effective and uncomfortable that work can actually be. >> at first glance it resembles a spacecraft more than anything else but this is a research sub that has combed the seas doing everything from medical research to ship and aircraft recovery. >> we have an array of light systems so you can turn on which ever light you need. >> jimmy used to spend 170 days a year on the sub. it's now retire d. >> all right. ready to go.

>> if this submersible could get to where the wreckage is, how effective do you think it could be? >> very effective. >> this is a view of a buried submersible. it can go 3,000 feet deep but like all research subs it's slow. it only travels just over 1 mile per hour when searching. the sub was called to duty in 1986 after the space shuttle challenger exploded and it recovered some of the wreckage. >> we have the capability of lifting around 1,000 pounds of weight to the surface. >> and the very front of the submersible, a tool called the manipulator which does the important work of grabbing, scooping and sucking up samples. >> this sub is about 24 feet long and about 11 feet tall and it weighs about 28,000 pounds. it has enough oxygen and emergency provisions aboard for the people to survive under water for up to five days.

>> there was also a bat cabin called the observation chamber. a crew member. >> so. >> this is how you're sitting. this is how i'm sitting. and we could be there for hours. >> this is what's taking place. >> so we fire up the sonar system and it takes a sweep. if there is any solid stargts it will people and we will go ahead and look at it that way. >> by looking for wreckage, manned submersible offer an important dimension. >> you're saying that sometimes having a human being being able to look around, i could spot things that an unmanned

submersible could not? >> correct. >> this submersible will not be going in an effort to solve a mystery. gary tuckman, cnn fort pierce, florida. >> i don't know if i could do that. such a relatively small area. how confident are they that they found the right spot? also ahead, a new video shows al qaeda's top brass in a bold public meeting. how did the u.s. miss it? also a frantic search for more than 200 missing here after the ship is buried and capsizes in south korea. what went wrong? some emotional text messages. ♪

>> welcome back. i'm brook baldwin. right now one blue fin device is believed to be scouring the ocean floor for any trace of this missing plane. now the blue fin 21 actually had two glitches and so now we are waiting to see whether the blue fin's third mission can finish without a snag. joining me now to discuss explorer and resident with national geographic society so ladies, welcome, so mary, i

would like to begin with you. i'm going back to this point. i can't understand why they're just using this one piece of technology to search for the wreckage. this one blue fin. does that tell you they are really confident in where they are? >> there is a little bit of both. he indicated that he only thought they needed one. there are only eight in the world. they are being used by their owners largely for underwater operations such as oil, communications and its they will have to ask for one from some other owner operator. >> i wanted to ask about that.

and i talked to a former accident investigator who is very familiar. he said they are using absolutely the wrong technology here. do you agree or disagree with that? >> i think the blue fin is a good piece of equipment and it's doing the job of surveying the area. there are other pieces of equipment such as were with the air france. it really takes one system but there really are not that many in the world. think about how many airplanes there are. it's only two and a half miles. the maximum has only been

reached twice in history. one of them was with 2012. the ocean is still largely inaccessible to us. that is not good news. >> as they look, can you -- remind us with air france, which auvs were used? i believe there were three that found the wreckage? and how did they find it? >> it was actually found using much the same approach that you're seeing now with the current blue fin system. autonomous underwater vehicles are relatively new. they were not available to find the titanic. depth is a big deal.

there are drones that can operate in shallow water to survey and bring back data. but sonar deployed equipment, here to fore towed rays have been used cameras are only operational in a very limited area. the sonar can see with sound over much wider area. and finding the wreckage is the key. and again, there are not many pieces of equipment aveil nbl the world that are capable of going to the depth where the airplane is thought to be. the average depth of the ocean. it's 2.5 to 3 miles down. >> i can't imagine it. i go back to the fact that they didn't find the wreckage until two years after the fact.

is there -- if they find nothing, closing up shot for a year, in the ocean, going back to just sheer science and then coming back with fresh eyes sometime later? >> they will have to do that. once they exhaust this area, the area surrounding the four pings and they are 17 miles apart. and obviously they will search all around the areas, but if they search all the area and they find nothing they will have to go back and regroup and see what else there is. that's all they have. >> thank you both very much for your expertise here. and as we talk, sylvia, forgive me. you mentioned the depth of the ocean. you think about the water pressure, the blue fin 21 facing a number of challenges. we will map out what the underwater terrain looks like.

>> i want to show you a piece of video. this is youtube video first reported on cnn. what it shows is the largest and most dangerous gathering of al qaeda in years. you can bet that the u.s. government is analyzing frame after frame after frame of this video 15.5 minutes in length. while critics are saying it is one huge missed opportunity for

drone strikes to take out top brass here including the global second in command in the video believed to be in yemen. he says we must eliminate the cross, the bearer of the cross is america. it's not clear if the u.s. simply didn't know about the gathering, couldn't get a drone there in time. what is clear are militants in an open air rally. al qaeda is making a bold move. >> the al qaeda threat today is more diverse and more aggressive with more threat streams than we have seen even since before 911. we think they are feeling empowered. >> out of the gate, we have to assume that al qaeda has a meeting of the minds. how concerned should the u.s. be?

>> well, from a counter terrorism point of view, the people that deal with this all the time, we're concerned, but we're not necessarily shocked or surprised. there has never been a belief, necessarily, with the operators in the field and others in the community that somehow we have beaten them down, they're not still there and targeting us. that part of us is not disconcerting. it's been interesting. the video came out. people have been quick to say how could the intel community not know about this? the same folks who belittle the community's efforts to monitor and understand what's going on. and the same people who complain about the drone strikes are saying how could they not attack them? how could they not have a drone overhead? >> it's possible that u.s. intelligence did know about it and did not get a drone there in time for a strike yes?

>> it's a possibility that i would be speculating. at the same time, it's not as if this is not like organizing the democratic national convention. >> this is al qaeda. i got it. >> this is al qaeda. and in yemen, they have got a very organized effort there. gathering up supporters, putting them in trucks and having a rally doesn't take a great deal of effort. and again, there was this effort for a period of time to say we have beaten them down and taken them out. we have. they do have what appears to be a bottomless well of potential recruits of easily manipulatable recruitable individuals who are willing to go to the dark side. >> there are things we see and don't see.

>> what is this presence trying to tell the world. >> he is becoming more and more visible in part, in order to stake his claim as a successor. to go behind the scenes. so i think part of this is the desire to say look, i'm a credible successor to this organization. part of it is to show that he is very comfortable in that environment. the al qaeda branch in yemen is a major concern for us. they show the most interest in

the capability to reach outside of the region to trik at potential targets here at the yuts and allies. >> who was in the video and who wasn't? thank you, sir. >> pretty stunning video from south korea where the rescue operation is underway. it is nighttime as i speak for hundreds of passengers after their ferry capsized in freezing cold water and a lot of the people on board, high school students. we will show you how the u.s. is helping in that effort. also theployed for a third time. we will map out for you the rough conditions its dealing with in a very unknown area of the world in the indian ocean.

>> we are just past the bottom of the hour and right now the best hope is thousands of people searching the indian ocean. cnn learned why the previous mission was cut short. a crucial oil actually ran low.

so a little perspective. imagine scouring chicago in the pitch dark. sit is it is a task that the u.s. navy admits will take two weeks to six months. you have ocean silt. those are just a few of the many challenges facing this piece of equipment. and tom foreman breaks down the other potential set backs that could affect the underwater search. tom? >> the challenges facing the crew operating the blue fin are really quite immense on the surface of the water. beneath the water it gets unbelievably complicated because they are entering a foreign and hostile environment in the deep ocean. it sounds simple. send this robot down.

let it ride around and take pictures of the ocean floor but they don't know what the ocean floor looks like. 95% of the deep ocean floor all around the world is unmapped. so what's the terrain like down there? is it smooth or craggy? how do you maneuver around all of that if you're not sure what you're dealing with? what about the pressure at the bottom of the ocean. push this thing down to two miles down. then you will have more than 4700 pounds per square inch. it's the same as if you had an african elephant standing on your big toe and this machine has to operate at that depth. it is not an easy trick. what about the bottom itself?

what is it made of? the ocean is full of silt. that's the left overbits of decaying plants and animals and volcanos and dirt. all sorts of things that have bled into the ocean over many period of times. that builds up on the bottom. there are cores taken of this that are routinely 100 feet in length. we don't know if it's solid or soft. all of this together, gigantic challenge for the blue fin that makes this much more experimental even though it's a great tool it's up against the odds. >> and another desperate search, many people missing are students and teachers from a south korean high school missing after their ferry suddenly sank.

kind of like the hawaii of england. unthinkable happened chl there was an announcement over the loud speaker saying don't move. here it is. >> don't move. if you move it is more dangerous. don't move. >> officials say at least six people are dead. many passengerers had jumped. and now military dive teams are searching for them and a u.s. navy ship also helping in the search. one expert says it is just an absolutely positively horrific situation. it's nightmarish. welcome to the cnn family, by

the way. you have been looking at web sides and different, and some have been texting with their kids on the ferry. >> it has been heartbreaking to read. some of the messages are the last messages that we're seeing from the passengers, most of them who were students sent it to their family members and friends. as you can imagine they are heart wrenching. one son said mom, in case i don't get to say this, i love you. his mom says why? of course i love you, too, my son. it's these kinds of messages that get to the heart of it. another student sent messages to his friends. he wrote to his friends at the school theater club and said i think we're all going to die.

there is another conversation between a desperate father and his teenager. i know there is a rescue mission underway but if it's possible get out of your room and the student says no, dad, the ship has tilted and i can't get out. no one st in the hallway. we don't know the fate of these students at this time. >> we know six people are dead, multiple others have been rescued. and then we played the audio saying don't move. >> we heard from survivors. and one said that the instructions given was to put on your life vest and stay put. it looks like many people may have obeyed. the people who did jump into the

frigid waters are the ones who probably survived. >> i just want to bring mary. >> some didn't listen to what the ship was saying. they were fine. what do you make of that protocol? >> the instruction to stay put is absolutely horrific. the instructions should be to get to the lifeboats and get the people off the boat. there have been ferry singeings and the ability to get them to those and get off the ship are what saved lives. >> it's nighttime right now. the waters, i believe, are in the pal park of 58 degrees.

what is happening in this rescue effort? >> a good part as you can see from the pictures, a good part of that ship will be used from water. there was a very large breach in the ship from whatever it hit in the hull if it did hit something and that sounds like what happened or from the doors itself. that allows water to rush in quickly. you can't fight that inflow of water. if you didn't get out at first it was very hard to fight through that water. but the coast guard has been able to rescue people like that. they go on the ship with their diving gear and will do it. >> hopefully the u.s. is able to

help as quickly as they possibly can. thank you both very, very much. >> minutes from now, president obama will be speaking at a community college and he says one of the answers is job training colleges in schools. live pictures now from pennsylvania. we will see the president speaking minutes from now.

>> here is something for you, something a bit unusual. what we will see, president obama, and vice president biden a rare joint appearance outside the nation's capital. they are in oakdale, pennsylvania, at a community college in allegheny county. jake, why the joint appearance and tell me what they're up to.

>> here's the problem. about a half of employers who are looking for employees say that the pool that they're drawing from, the workers don't have the skills they need. so you think that vocational and technical schools, community colleges would be talking to local employers and trying to match them and make sure that what they are teach something relevant but they're not. what the administration is trying to do is devoting $600 million to this, trying to get schools and employers better attuned to one another in terms of what employers need and what the schools are teaching. it's common sense but it's not happening. >> when we talk about the skills and when they do talk they will be able to help the students get the jobs. what kind of jobs are we talking ability? >> over the next eight years from 2012 to 2022, these are the

jobs that will be open. there will be 522,000 computer software and programming jobs that open up. more than 100,000 pharmacists, 224,000 electricians and 132,000 welders. we're talking about potentially millions of jobs that will be open if the americans have the skills that are necessary. >> we are watching live pictures. we will see you at the top of the hour. thank you, sir. and coming up next we will take you back to the search iffer the missing plane. but first the growing crisis in ukraine. pro russian mill tands with a face off in the east. we are live on the ground to show us the unfolding drama.cri.

u cain's attempt to calmties near the border went nowhere today. troops failed. fighters loyal to muss corumbled in ever greater numbers. in several cities, you have the pro-russians and their supporters sharing same streets with ukrainian troops and their supporters. very, very confusing and potentially, very, very

explosive. cnn's nick paton walsh in the midst of the chaos and joins me with a little bit more. nick, just to be blunt, i mean, imagine not a proud day for the ukrainian military, i gather. >> reporter: there's been a remarkable to watch them move around this part of eastern ukraine. now, this morning, a column of ukrainian went into one of the cities to the south of a place where has been the focus very much, the pro-russian protesters here. they were met as they went in by local residents, it seems, who surrounded them, slowed them down. we've seen quite a lot of that over the past few days and the pro-russian militants, pretty well equipped and organized, disciplined guys, turned up and took control of the armored personnel carriers. five or six drove them to a town where it's pretty much pro-russian, protesters in control there. raided them, and the city center, and then drove off with them in one direction.

ukrainians inside there, taken to a din building and fed lunch by the self-declared mayor saying they hadn't, quote, yet surrendered. clearly a change in control of the vehicles. something else similar, we witnessed, too, in a village where we saw another ukrainian column of armor come in, according to locals fired shots in the air, damaged a car as they drove. that made residents very angry who again surrounded these ukrainian armored personnel carriers and a deal was struck in which the ukrainian soldiers gave up firing pins in their weapons in order to secure passage out of there. an extraordinary, messy day for those little interventions we've seen of the ukrainian military and what kiev will see is an all encompassing anti-terror operation to regain control of here. >> nick, just given all of that you have seen from your

perspective, is the ukrainian military any factor in all of this? >> well it's the readiness that's the factor. they've come into the area, unprepared. the unit we saw was supposed to be almost elite paratroopers surrounded by local residents and looked exhausted, ill equipped, too. messy response. the ukrainian security forces moved in saturday and got ambushed on the way in, losing one of the guys killed, five injured and since then tried to build up forces, move around and each time stumbled. we see a lot in the sky, jets and helicopters but no presence on the ground. >> nick paton walsh, thank you so much. on wall street, positivity with the dow rising. look at this more than 140 points. alison kosik joins me to talk about why stocks are doing well.

quiet! mom has a headache! had a headache! but now, i& don't. excedrin is fast. in fact for some, relief starts in just 15 minutes. excedrin. headache. gone. [ female announcer ] most of the time it's easy to know which option is better. other times, not so much. so it's good to know that mazola corn oil has 4 times more cholesterol blocking plant sterols than olive oil. and a recent study found that it can help lower cholesterol 2 times more. take care of those you love and cook deliciously. mazola makes it better.

just a couple minutes away from the closing bell. any guess what wall street's up to? ♪ because i'm happy clap along if you feel ♪ ♪ like a room without a roof because i'm happy ♪ ♪ clap along if you feel♪ >> they're happy. we just wanted to hear that. thank you, pharrell. a good excuse to play good music before i let you go. alison kosik.

>> how can you not feel happy when you hear that? >> love that song. anyho, talk to me about the numbers, dow up before the closing bell. >> you know what? wall street doing its own happy dance, solid headlines. earnings have been pretty good, keeping stocks in the green. also, fed chief janet yellin reassured investors saying that interest rates will stay low, that means borrowing money will continue to be cheap. l plus economic growth in china slowing down but not as fast as expected. you get a lot of green arrows on the screen today. seeing triple digits to the upside. this is today. look at how the market's been lately, lately it's been volatile. we've been getting, i don't know, whiplash lately. trip triple digit swings yesterday, stocks down for the month because we've been getting mixed signals from earnings season overall. today, up arrows, yes, seem to be the pattern. >> we'll take the green on the

screen. investors will take the green on the screen. you had me with the tweet, 60 seconds to explain this, james bond type kill switch coming to i cell phone near you. >> think james bond kill switch, coming to a cell phone next july. so what this would do is allow you to be able to remotely disable your phone, wipe all of your personal data off 0. why do this? because if a crook steals your phone he's going to get your information potentially. this hopefully deters thieves from stealing the phone in the first place. this is a pledge by phone companies and carriers to put this kill switch in action in their phones, you know, companies like apple, google, samsung, carriers like verizon and at&t. it's just a pledge. no one's enforcing this. but at this point, some states are working on laws to make this kill switch mandatory, so what you may see happen, if companies don't get in there and do it, some states may pass their own laws to get it done anyway.

brooke? >> on cue, the closing bell. alison kosik, thank you so much, in new york. that does it for me. i'm brooke baldwin in atlanta. if you missed anything go to the brooke blog. now, jake tapper starts right now with "the lead." >> i'm no jacques cousteau but wouldn't two robo subs be better than one? that mission? i'm jake tapper, this "the lead." the world lead, the tool moving forward to search for the missing plane, that bluefin-21, and it's back in the deep this hour. every other time it's gone down this week, it's come back, way too early. is this the best method? new questions why the co-pilot's cell phone was on after the plane made its wild left turn. was it on the whole time? did it show up anywhere else? was he trying to call someone? also, in world news, heard about those widespread attacks on ethnic russians in ukraine? they're a complete inven,
