we haven't found anything yet in the area we're searching, but the point i make is that australia will not rest until we have done everything we humanly can to get to the bottom of this mystery. >> cyy's erin mclaughlin is live in perth, australia. i want to go back to this item of interest. >> reporter: the head of australia's transportation and safety bureau saying they're analyzing photographs of that object. he describes it as sheet metal with rivets, telling cnn it appeared to be covered with fiberglass, saying it was described as kind of rectangular but torn and miss shape en. dolan saying while it is interesting, he added a note of caution saying the more they look at the photographs, the less excited they get.

we understand that australia media was reporting that perhaps more than one object was found. cnn not able to confirm those reports. we understand the object is currently in police custody. atsb saying the current photographs they have are more than enough for them to be able to make an assessment if it's connected to mh370. >> erin, did this object of interest wash up onshore? if it did, have there been other objects they found onshore that turned out to be nothing rfr it did wash up onshore about 190 miles to the south of perth. if other objects have washed up that were remotely interesting, we haven't been notified. this is the first item of significance that they have thought to call to the media's attention in this search for debris. there have been plenty of items

or sightings found by any number of military planes that take up into the skies every day, scouring for any signs of mh370, all those sightings so far having been ruled out. >> erin mclaughlin reporting live in perth. joining me, thomas altshuler the vice president at teledyne marine systems. welcome. >> good morning. >> good morning. let's talk about this possible debris, an object of interest. it washed up onshore. a long piece of metal with rivets. should we be at all optimistic about this? >> i think we need to be cautious. the first thing -- we said it a lot. we said it about the acoustic noise. the ocean is full of stuff. i'm going to say stuff because it has acoustic energy in it, things that have fallen over ships, things that have washed offshore. there's a lot of material in the ocean. so it's not outrageous that it would be completely not

associated with the flight at all. at the same token, it's in an interesting spot. so it need to be investigated very carefully. one of the things to think about is that there are great coastal oceanographers in the western part of australia out of university of western australia. they study the currents, how the weather influences how material will move. i'm sure they're involved in this, looking at whether it's possible that something that came down 1,000 kilometers away over 45 days ago would make it all the way to the coast. >> other developments, the malaysian cabinet putting together an international investigation team to look into the disappearance of flight 370. no word on who will be on the team. how difficult might this be? >> i think this is a very unique situation. you're looking at both -- some of the classic questions that happen when you have a disappearance or a loss of an airplane. but now you're looking at a loss potentially in the deep ocean. that team is going to have to be

made up of experts. some of them are barely used in this situation. you a small pool of people to go to. you need to have very thoughtful people. i think it will be a shall cheng, but there are people out there that can add to what's going on out will. >> the other development, mall lash yes, sir civil aviation organization finished a preliminary report on the plane's disappearance but hasn't released the report publicly. the families are angry about this. it should release the preliminary report. why not? >> that's a hard question to answer. we aren't inside the minds of what the report writers are thinking and how confident they are of their initial findings. you're always going out on a limb. if you release data early, it's open to interpretation. as you can see with some of the things that have come out very quickly in the last 45 days, the

risk of saying something that gets interpreted one day and even drives the community in the other. they need to be thoughtful, but they need to be open about what they release. >> thomas altshuler, thanks for your input. the united states now sending 600 troops to poland and three baltic states. the first group arriving today with everyone likely in place over the weekend. russia announcing it will send troops to the cass caspian sea. they say it's no training exercise, it is a message to russia, get out of eastern ukraine now. >> since russia's aggression in ukraine, we have been constantly looking at ways to reassure allies and partners. >> this isn't the first time that the 173rd has done exercises with these countries. there's a relationship there.

yes, these exercises were conceived and added on to the exercise regimen as a result of what's going on in ukraine. >> in the meantime the ukrainian government is renewing its call for what it says is an anti terrorist operation, targeting four russian militants in four key cities in a bid to regain control of the eastern part of the country. it happens after two tortured bodies were discovered in the region, one belonging the a local parliament member. ukraine blames pro-russian militants. but a pro-russian leader blamed the deaths on ukrainian extremists. pentagon correspondent barbara starr joins us. good morning, barbara. >> good morning, carol. as you saw the admiral say there, this is about 600 troops from a unit called the 173rd

airborne brigade. the troops are already in europe. about 150 u.s. troops, paratroopers per country, poland, lithuania, latvia and estonia. they will be in place by monday to exercise with these four countries for about 30 days and then other u.s. troops will rotate in -- it may expand to other countries. they're going to try to get nato countries to offer up troops to do this. it really is a two-pronged effort. it is a message to moscow, get out of ukraine. no question about that. it is a message to reassure these very nervous east european allies. russia sits on their border and they're increasingly concerned about what russia's intentions are, what russia may do next. this is an effort to reassure them and say the u.s. will stand with them. 150 troops per country. not a lot, but it is a clear

message. carol? >> barbara starr reporting live from the pentagon. still to come in the "newsroom," the critical minutes that doomed the singing ferry. cnn's rosa flores shows us how training can be the difference between life and death. rosa? >> i'm here at resolve maritime academy. this is a full-blown bridge simulator. right now you can see there's thunder and rain. we'll be adding more complications right after the break.

off the coast of south korea, a grim discovery aboard the sunken ferry. divers say they have found no

air pockets, virtually eliminating any hope that survivors are still trapped in the submerged hull. in the meantime the death toll crimes and the list of criminal charges grows longer. let's get the latest on this deepening catastrophe. cnn's will ripley is in south korea this mornings. hi, will. >> reporter: hey, carol. all this time divers have been working tirelessly around the clock searching for the possible air pockets inside the sunken ferry, the sewol. today that announcement comes as a blow to the families holding on to the possibility of an air pocket, hoping someone might be alive. they searched the third and fourth floors, where passengers were believed to be. many of them young students. that search turned up only new bodies. the death toll 156 which is the first time the number of dead is higher by ten than the number of missing which is 146 officially. we're seeing the continued

activity for days, boats coming back to shore bringing bodies. along with those bodies come very, very grief-stricken families. >> will ripley in south korea this morning. the criminal charges against the ferry's captain and ten of his crew members hinge on one critical presumption, they're entrusted to respond quickly to an on board disaster and save the lives of their passengers. cnn's rosa flores is about to walk us through some of that training. she's in a bridge shim later in ft. lauderdale. good morning, rosa. >> reporter: good morning. cruise liners come here to this facility to train, to do drills so they can avert tragedy. this is resolve maritime act me. i'm here with dave boldt. dave, what are we looking at? >> this is an integrated bridge system, exactly what you'd see on a large vessel. >> right now we're seeing

thunder and rain. one of the things we can do is start listing this ship. focus on the horizon and you'll be able to see a perspective as to what it would look like. we have a second camera, and i want you to take a look at this. this is the perspective that passengers would have. take a look at that. you can see how close the life boats are to the water, perhaps some of those windows that might be closer to the water. dave, at this point if you're on the bridge and you're commanding the ship, what's going through your mind. what are you communicating? >> a captain would know something is wrong if you're stuck at this point and you're listed over, it's either a flooding issue or a grounding scenario. there's specific things you do. they train for that every month. they go ashore and train for those things. they'd be communicating with crew members and crew members would be communicating with passengers. >> we got a rare look at what could be happening below deck. take a look.

on a ship this is the universal sign of trouble. inside this model ship hull, instructors from resolve maritime academy train crew how to prevent a deadly disaster at sea like the sinking of the passenger ferry in south korea. investigators say the nearly 7,000-ton ship sank in about 2 1/2 hours. 476 people were inside when a boy on board made the first call for help at 8:52 a.m. local time. the ship's crew made a distress call about three minutes later at about 8:55. the crew's response is critical to preventing disaster. in this scenario water is rushing in from an unknown source. >> water is starting to rise. what do you do? >> the main thing is just get away from the damage.

get inside and let the crew know if you find damage. >> they use anything they can to plug the holes. >> how much time do you really have to get out or to assess the situation when water really charts just gushing in? >> it all depends on the scenario, how deep the hole is inside the water. naturally the deeper the hole the more water pressure is pushing in. >> if i'm a passenger on a ship and i'm not very familiar with the ship, what do you suggest i do to get to safety? >> the best thing to get to safety is follow the walls, get to a ladder, get outside. i always recommend getting to the main deck. >> reporter: of course, he's referring to the deck where the life boats are. we're back here with dave. dave, talk to us about the training that is required for someone that is on the bridge that's at the helm of a ship like this? >> there's training in schools. they do several years of

training, they get their licenses. and there's time at sea and that's how they get ahead and get to the higher ranks. there's no requirement for recurrent training in this kind of a situation. we built this for some cruise line clients that we had, and they do recurrent training. we're starting to do this training regardless of international regulations. >> reporter: carol, one of the big things we can take home from here is that's the reason why these simulators are here so that cruise lines can practice, they can go through drills and avert disaster. carol? >> rosa flores, many thanks. still to come in the "newsroom," a 15-year-old boy is in the hospital after surviving a five-hour flight in a plane's wheel well. why did he attempt such a dangerous stunt in the first place? cnn's dan simon is in san jose, california, with answers. good morning. >> reporter: good morning, carol. what exactly motivated that 15-year-old to get into that wheel well and make that trip to hawaii? we have new information about

what he told fbi investigators. we'll have that story coming up. if you wear a denture,

take this simple test. press your tongue against it, like this. it moves! do you feel it? it can happen with every denture. these movements may irritate your gums. but you don't have to bear with it. you can try fixodent plus gum care. thanks to its formula, your gums become one with your denture. this helps stop movement and helps prevent gum irritation so you can keep enjoying life.

[ apple crunches ] fixodent. and forget it.

we now know more about why a teenager stowed away in a wheel well of a plane. the 15-year-old wanted to see his mom in somalia. as for his health, we're not sure. we know he's recovering though he may have permanent brain damage after flying in extremely frigid temperatures with low oxygen. cnn's dan simon is in san diego with more answers for us. good morning, dan. >> reporter: good morning, carol. it kind of seems like this is a

teenager who was homesick, who acted out in an irrational manner to say the very least. what we understand is he told fbi investigators that he wanted to go to somalia and visit his mother. in fact, classmates at his high school in santa clara, california, tell us he said that he was from africa and that he ultimately wanted to move there. why did he choose a hawaiian airliner? apparently that was just the first plane he saw when he hopped the fence. we're also getting new information, carol, in terms of the timeline. we understand he hopped the fence here at the san diego airport at approximately 1:00 a.m. sunday morning. keep in mind the plane didn't take off until just before 8:00 a.m. that means he would have been on the tarmac or perhaps even in that wheel well for approximately seven hours before it even took off. keep in mind the flight itself was five hours. he's in this maui hospital still

recovering. he's said to be in very stable condition and at a certain point we understand authorities there or wild welfare officials are going to make arrangements to get him back to california. >> i was wondering about his family in california. are they with him? >> reporter: we don't know where they are. we were actually in that neighborhood yesterday. we knocked on the door to the house. there was no answer. they apparently moved to that neighborhood not too long ago. so when you talk to neighbors, few folks are familiar with the family. we also understand he enrolled in the high school just a few weeks ago as well. they were relatively new at least to this part of the bay area. >> as for this san jose international airport and security improvements there, now that we know more of a timeline, have they filled the holes in their security? >> reporter: at this point they haven't done anything. what we know is that the airport

director is now essentially on the record saying they're going to be investigating what happened, obviously. they have said previously that all of their standards, their perimeters met tsa standards. it's clear based upon this incident that something needs to be done. it's something that not only applies to shaig, carol, but other airports across the country. it seems rather obvious that there are breaches in the system that somebody easily can hop over a fence at least here in san jose. it begs the question, if a teenager could do it, a terrorist could do it as well and maybe put a bomb in a wheel well. that's a terrifying thought. >> dan simon reporting live. thanks so much. still to come, a serious lead in the search for flight 370. is it a break through or another piece of ocean debris. we'll ask the former inspector general for the u.s. department of transportation next.

[ male announcer ] this is jim. a man who doesn't stand still. but jim has afib, atrial fibrillation, an irregular heartbeat not caused by a heart valve problem. that puts jim at a greater risk of stroke. for years, jim's medicine tied him to a monthly trip to the clinic to get his blood tested. but now, with once-a-day xarelto jim's on the move. jim's doctor recommended xarelto. like warfarin, xarelto is proven effective to reduce afib-related stroke risk. but xarelto is the first and only once-a-day prescription blood thinner for patients with afib not caused by a heart valve problem that doesn't require routine blood monitoring. so jim's not tied to that monitoring routine. [ gps ] proceed to the designated route. not today. [ male announcer ] for patients currently well managed on warfarin there is limited information on how xarelto and warfarin compare in reducing the risk of stroke. xarelto is just one pill a day taken with the evening meal. plus, with no known dietary restrictions,

jim can eat the healthy foods he likes. do not stop taking xarelto, rivaroxaban, without talking to the doctor who prescribes it as this may increase the risk of having a stroke. get help right away if you develop any symptoms like bleeding, unusual bruising, or tingling. you may have a higher risk of bleeding if you take xarelto with aspirin products, nsaids, or blood thinners. talk to your doctor before taking xarelto if you have abnormal bleeding. xarelto can cause bleeding, which can be serious and rarely may lead to death. you are likely to bruise more easily on xarelto and it may take longer for bleeding to stop. tell your doctors you are taking xarelto before any planned medical or dental procedures. before starting xarelto, tell your doctor about any conditions such as kidney, liver, or bleeding problems. xarelto is not for patients with artificial heart valves. jim changed his routine. ask your doctor about xarelto. once-a-day xarelto means no regular blood monitoring -- no known dietary restrictions. for more information and savings options,

good morning. i'm carol costello. thank you so much for joining me. in western australia search officials are speaking cautiously about an object of interest found in the search for

flight 370. the object was picked up less than 200 miles from perth onshore. as you know, perth is the hub of the search. this object is described as sheet metal with rivets. now, it's not clear if it's related to the missing plane. some officials are already voicing doubts, but it is being tested. in the meantime malaysian officials have completed their preliminary report on the disappearance of the plane and its initial handling, but malaysia is refusing to release that preliminary report publicly, further infuriating victims' families who says the government and airline are ignoring even the most basic questions. >> they must have covered up something and want to hide something. some of the questions are totally not confidential. it is a fact, i don't know how it could influence the investigation, but they just give the answer that, oh, it is still under investigation. it is not an answer.

>> let's get the latest from cnn's richard quest and cnn aviation analyst mary schiavo joining us. richard, you were at the press conference and asked authorities to release the preliminary report. what did they tell you? >> reporter: first of all, under the iko, the international organization that governs all civil aviation, i wanted to know under the rules, they were supposed to provide a report to iko within 30 days. so my question was simple. it was have you provided a report? if you have, will you make it public. and this was the reply from the head of civil aviation. >> yes, we have issued the preliminary report and we have sent it to iko. we have not made a decision yet whether to release it to the media or to the public.

>> reporter: so the report has been sent. and i also understand that as is normal in these reports, there is a safety recommendation. it is that all commercial airliners should be tracked in realtime this first report, it must be said, it would be very basic, a simple statement of facts, nothing complicated, no analysis, nothing controversial. but i think the fact that it has been presented, and we weren't even told that fact, let alone the report being made public, it's enough to sort of, once again, maybe raise an eyebrow. >> haven't the malaysian authorities been listening to these families, listening to criticisms about how it's not being transparent, how it's making things form difficult for itself. if it's a similar report, why not release it? what's the big deal? >> reporter: and that is the

pretty unusual point. look, i went back. go back to air france 447, go back to qantas in singapore where the engine blew up, go back to british airways which crash landed at heathrow. in all those cases a preliminary report or basic statement of fact was presented within a timely area. we never got anything like this. i'm at a bit of a loss to explain why in these situations except to give them their due, they are dealing with a unique set of circumstances here where there is no plane and most of the efforts at the moment has to be find a plane because without the plane you aren't really going to have an investigation. >> well, that is certainly true, mary schiavo. but still, i mean the preliminary report is done. the work is done on that report. why not release it? >> let's not overstate what the

preliminary report is. either preliminary reports are unbelievably simple, it's basically a jack webb, just the facts, ma'am. the fact they put a recommendation in there is somewhat remarkable because that usually comes in the last report, the recommendations report. it's very simple, very straightforward and nations around the world make them public. the ntsb pop them up on the website just about as fast as they write their preliminary report. there's no reason not to put it up. it would not have any unresolved critical investigative secrets in it. it's just the facts. there's no explanation and no excuse for it really. >> let's move on and talk about this object of interest. richard, did they say anything at all in malaysia about this piece of metal that supposedly washed onshore in australia. >> reporter: no.

well, yes and no in the sense it was raised at the press conference. they certainly knew about it. it was a couple hours ago, this press conference. it was in realtime, if you like, to what was happening in western australia. yes, they knew about it. they hadn't heard any facts from western australia at that point about whether this was more than we already knew. a piece of metal with rivets which may or may not, pardon the phrase, be of importance. >> mary, we've been down this road so many times where objects of interest were found and they turned out to be nothing. >> right. this may very well, too. what's got people sbefrted is it's a piece of metal with rivets. the wings of a 777 have mail eun rivets or aviation fasteners. so does the fuselage. when you see metal with rivets, it will be of interest. they said it had some insulation stuck to it. insulation on an aircraft is very unique.

it's like pillows lined up on the wall. they'll be able to tell right away if that's aircraft insulation. it's a very special flame resistant polymer. >> i know they're doing analysis as we speak. richard quest, mary schiavo, thanks to both of you. still to come in the "newsroom," u.s. troops now caught up in the crisis in ukraine as the pentagon launches military drills in eastern europe. is diplomacy done? we'll talk about that next. they think about tires. and what they've been through lately. polar vortexes, road construction, and gaping potholes. so with all that behind you, you might want to make sure you're safe and in control. ford technicians are ready to find the right tires for your vehicle. get up to $120 in mail-in rebates on four select tires when you use the ford service credit card at the big tire event. see what the ford experts think about your tires. at your ford dealer.

the pentagon is backing up vice president joe biden's vow to stand by ukraine. it announced that u.s. troops will be deployed to poland and three baltic nations in response to russia's actions in the region. russia for its part says it will

now begin military drills in the caspian sea. the pentagon says its actions are an attempt to, squoet, reassure allies. concerns are growing in asia as well that if russia is allowed to take over more of ukraine, it could embolden north korea and iran. i want to bring in nicholas burns from harvard's kennedy school of government. welcome, mr. ambassador. >> thanks, carol. >> so the u.s. is sending troops to eastern europe. does that mean diplomacy is officially dead? >> i think the administration has calculated it quite rightly that diplomacy is not going to get us far with putin because he doesn't want to negotiate anything seriously. he's trying to destabilize eastern ukraine. president obama, quite rightly, has tried not to make this a military contest between russia and the united states. what can the u.s. do?

two things. it can move some of our troops not into ukraine, but into those eastern european countries that are members of nato to which we have article five in the nato treaty, collective security guarantee. the countries need a similar lolic reenforcement. it won't be large numbers of u.s. troops. it sends a signal to president putin his ambitions can't go as far as the nato territory because we have this commitment to them. the other thing we can do is raise the economic cost through sanctions. i think the u.s. is pursuing the right strategy. in particular, vice president biden's visit yesterday to knew crane was very important because the ukrainians need that assurance that the united states and europe are behind them economically and politically and will try to help them emerge from the crisis as best as they can. >> well, i don't know. if you look at it this way, there are 40,000 russian troops

amassed on ukrainian's border, on the border with ukraine i should say, the russian side. there's 40,000 troops. we have maybe 1,000 troops, american, in eastern europe. might the pentagon feel the need to send more if this thing keeps escalating? >> i think the president is being very careful here. we're not going to be in a position where the united states begins to build up an armored core against those 40,000 russian troops. it's not going to happen. we're not deploying to ukraine at all. the united states is the leader of nato. that's our most important and successful alliance, in business since 1949. the members of nato that are potentially in the future vulnerable to russian interference, vulnerable to intimidation, they need the symbolic visible support of the united states. i think moving a couple thousand

troops into this area does make sense because it's a siggal of our continued commitment to those countries. i think the president has done the right thing. >> i understand symbolic support. couldn't that translate to empty threat? >> no, because we're not making a threat. we're not threatening the 40,000 russian troops, not threatening president putin. what we're doing is saying he can not redivide europe the way europe was divided in the cold war and that the united states will, in effect, with europe stand by these smaller allies. the baltic states are particularly important, carol, because they were forcibly incorporated into the soviet union in may 1940 and treated very, very badly. their liberation from the soviet union in 1991 was a real victory for democracy and freedom. we stood beside them for a long, long time since they became members of nato. a great power like the united states has to act like a great power with a certain amount of self-confidence. i think this is the right decision and one would help

president putin will understand there are limits to what he can do in eastern europe. >> former nato ambassador nicholas burns, thank you for your insight. i appreciate it. >> thank you, carol. here is what's new on the next hour of "newsroom," i'll be talking to congressman peter king to see if he thinks it's time to give up sanctions against russia. we'll look at new technology that could be used to look for victims of the south korean ferry disaster. that's all new on the next hour that's all new on the next hour of "newsroom." i'm k-a-t-e and i have copd, but i don't want my breathing problems to get in the way my volunteering. that's why i asked my doctor about b-r-e-o. once-daily breo ellipta helps increase airflow from the lungs for a full 24 hours. and breo helps reduce symptom flare-ups that last several days and require oral steroids, antibiotics, or hospital stay.

you. you see some problems in "the new york times" study. what is that? >> well, two big things to point out when you're looking at these numbers. first of all, a dollar earned in norway is not like a dollar earned in the u.s. it's called purchasing power. in the u.s. we have more of it. you have to earn $52,000 in norway to live like someone who earns 34,000 in america. in canada, there are similar discrepancies. $34,000 in canada translates to 27,000 in the u.s. the second is, if you dig into the numbers of income and equality, what's very interesting is on a pretax basis, the u.s. has less income inequality than other countries we cite. on a post-tax basis, we the middle class aren't getting that money back from the government. with a lot of the european countries and canada, more is

actually from our tax dollars is being channeled to programs from the middle class. and when you factor in that we're collecting about the same amount of taxes per capita in the u.s. and these other countries, that starts to point the finger at the way we spend money, the way the government spends money, and how we prioritize these dollars and why we're not able to get the same kind of services for the american middle class. >> got you. i want to put up a chart. i hear you. this is the chart that "the new york times" provided and you can see the lack of wage growth the united states has seen since the year 2000. britain's middle class wage climbed 20% since the year 2000. canada, 20%. take a look at the united states. that's nothing. >> yeah. there has been very little wage growth. over the last five years, the american middle class has actually lost $2,000 of income. i agree with monica. this idea that middle class in the united states is not as well off as those in europe and

canada is extremely flawed. anyone who has been to ireland or france or italy or spain or greece recently knows that american middle class do better. >> what about canada? we know that in the countries you mentioned they had a terrible economic crisis like we did. >> there are some scandinavian countries like sweden are doing well. canada actually is doing very well, carol. what's interesting, two points. one is i don't understand what this has to do with income inequality. the reason the middle class isn't doing well is because there is not jobs. there is not economic growth. when you don't have those things, you don't have the middle class doing well. it has nothing to do with the fact that warren buffett and bill gates have so much money. the other point i would make is canada has done a lot of the right things recently. they did not go off to this big spending and borrowing binge that we did in the united states in 2008 and '09 and '10.

they balanced their budget. they're paying their bills. they cut their tax rates. we could learn a lot from canada on how to turn our own economy around. >> stephen says we can learn a lot from canada. you don't hear that very often. >> yikes. >> i want to say one thing about income inequality. according to the census bureau, the average american household in 2012 made about 50% less than the median corporate executive. i'm not talking about those executives that make in stratosphere. executives that made in the six figures. that's a business disparity, isn't it, monica? >> the point is to make a better life for the middle class and the more we focus on populism we're not really addressing the problem. if you actually start digging into the numbers, you're seeing that a lot of the money that the middle class pays into taxes isn't coming back to them and that makes a very big difference in terms of their life and how their life gets lifted back up. if we want to give americans a

better life, we need to be more targeted about how we spend money. we can't afford to be inefficient anymore. >> you're right about that. monica, stephen, thank you for your insight this morning. i appreciate it. ahead in the next hour of "newsroom," australia refuses to abandon the search for the flight. who will be in control of the team? we'll talk about that in the next hour of "newsroom" after a break. they can help protect us from a world of unseen danger. it's the stuff of science fiction... minus the fiction. and it is mercedes-benz... today. see your authorized dealer for exceptional offers through mercedes-benz financial services.

happening now in the "newsroom," object of interest. a tantalizing bit of debris washes up on the australian shore. >> described the object as sheet metal.

>> australia will not rest until we have done everything we humanly can to get to the bottom of this mystery. plus, no air pockets. hope for a miracle fades as more crew members are taken into custody. >> we're learning that a young student onboard the ship was the first one to call emergency services. also, a message for russia. u.s. troops arrive in eastern europe. >> no nation has the right to simply grab land from another nation. >> ukraine ending its easter truce. >> it looks as if at this stage the geneva agreements are not worth the paper they are written on. >> president obama heads to asia. you're live in the "cnn newsroom." good morning.

i'm carol costello. thanks so much for joining me. we begin with developments in the search for the flight. officials are calling the lead serious but some have expressed doubt. stormy weather delayed air searches for a second day. below the waves the bluefin-21 continues to hunt. the underwater drone will wrap up its tenth mission. no matter the challenges, the australian prime minister says the search will not be abandoned. >> we haven't finished the search. we haven't found anything yet in the area that we're searching. the point i make is that australia will not rest until we have done everything we humanly can to get to the bottom of this mystery. >> we go live to australia for more on this object of interest. where exactly was it found? >> reporter: hi, carol. we understand it was found

around 190 miles to the south of here to the south of perth. the australian transportation and safety bureau chief telling cnn that the ntsb is in the process of assessing and analyzing photographs of the object. he described it as a sheet of metal with rivets. a source within the australian defense force saying it appeared to have been coated in fiberglass. it was described as a rectangular but torn and misshapen. it was sufficiently interesting but he did add a note of caution saying the more they look at these photographs, the less excited they get. we are aware of australian media reports that more than one object has been found. cnn has so far not been able to independently confirm those reports. we're also trying to get a better idea of the size of the

object. we understand according to the australian maritime authority that it is currently en route to perth for further analysis. carol? >> let's talk about this some more. i want to bring in david, a cnn safety analyst and the author of "why planes crash" and thomas is the vice president of marine systems. welcome to both of you. >> good morning. >> hello, carol. >> david, let's talk a little bit more about this object of interest. so many pieces of debris have been found. we've been hopeful and then our hopes are dashed. what do you think about this latest find? >> i don't like the way it was described first of all. they said a piece of sheet metal. that's what the structure of this aircraft is aluminum and that's distinguishable particularly if it's from this aircraft on the inside it would

have a green color. most of the aircraft parts even the sheet metal parts on this aircraft have an identification number on them. if it was a smaller part, you may not see that. the idea of fiberglass somehow attached to it, it just doesn't ring true with me as far as part of this aircraft. i can see the skepticism and why the prime minister didn't mention it until he was questioned about it. >> thomas, it washed up onshore, whatever it was, right. so how likely is it that debris from this plane would wash up on the shores of australia? >> well, very much depends on where the plane went into the water. if you take away the search areas right now, look at the storms, look at how the big ocean circulations work there, it's possible but david is absolutely right. the airplane, 777 is a complex system. boeing knows their plane very well. it will be easy to identify

whether it's from that air frame at the end of the day. >> investigators are looking at it now. we should know soon and that's a good thing. david, malaysia says it finished its preliminary hearing report on the disappearance of flight 370. but authorities say they will not make it public. why? >> that's a really good question. the preliminary report is a requirement and as i understand that preliminary report and as i understand annex 13, the responsibility is malaysian airlines to provide survivors of an accident what they think it is at that point so why it's not being made public, i have a question into the ambassador for the u.s. and i'll have an answer from that i hope today as to why it's not being made public. >> it makes them seem so -- of

course they seemed tone deaf through all of this. the families want answers. give them this preliminary report. what's the big deal, thomas? >> well, you know, again, i think there will be requirements they need to meet but i'm unsure what will be in the preliminary report. they have been pulling data out of many different places. there is risk the data is highly inconclusive and maybe inconsistent. should it be released if there are requirements that it needs to be released? it should. but i'm not convinced that the report is going to have a lot of satisfying information in it. >> probably not. another development this morning. the transport minister says an international team will now take up the investigation. they haven't named who's on that team but who should be on that team? >> certainly with any investigation they need to have any part of the aircraft that's

manufactured, you need the manufacturer's representative particularly the engines. there should be representation from the manufacturers, from anyone along the operational chain of the aircraft including repair facilities, anybody else who had something to do with that airplane needs to be participating on the team. as far as leading it in responsibility, malaysia cannot simply say it's out of our hands. we're handing that over. they have to stay in control of that investigation unless they're deemed to be not have the equipment or the experience or capabilities to do so. they have been quiet in this so far. i don't expect they're going to step in saying this is what has to be on there. >> thomas, this could be a good thing that this international team is being formed right now? >> fresh eyes are probably critical at this point. you're 45 days into this. there's been a lot of false starts and inconsistent

information. bringing in a new group, bringing in a very experienced group to evaluate and investigate has really no downside at all. >> david, thomas, thanks for your insight this morning. i appreciate it. the crisis in ukraine showing no signs of deescalating. russia isn't backing down. it will deploy its own troops. the actions come as uk an raini officials restart anti-terrorism efforts. both sides blame one another for not enacting an agreement reached in geneva last week disarming some groups and returned seized buildings to their owners. we'll dig deeply into the

ukraine crisis later this hour. new york congressman peter king will be my guest. president obama is japan today kicking off a tour aimed at reassuring asian allies. white house correspondent traveling with the president. the timing is remarkable. >> reporter: it's interesting. in the midst of the ukraine crisis in which the u.s. has tried to take a lead in finding a diplomatic solution there, here comes this important asian trip in which some of the countries to be visited have similar concerns even disputes with china over territory. you can't espouse the values of sovereignty in one region of the world and not address it in another. one japanese newspaper already asked president obama about this dispute between japan and china over islands in the east china

sea. the president didn't try to walk a middle ground. he sided with japan. he said he believes japan is the rightful administrator of those islands and that the u.s. opposes efforts to undermine that. you look at the philippines and malaysia with their own issues with china. this is sure to be an issue we'll hear more about as this trip progresses. carol? officials now say that the massive and unprecedented attack in yemen killed 65 suspected al qaeda terrorists. sources say u.s. forces supported the joint strike from the air using russian made yemeni helicopters. cia drones are expesuspected of targeting the fighters. now dna tests will determine if an al qaeda mastermind was killed during that very strike. he may be among the dead. believed to be al qaeda's top

bombmaker. we're joined now from washington with more on this. the cia went into that strike zone and collected bodies and dna and sent samples to saudi arabia. that how is that how it worked? >> that's right. there are a lot of questions as to if he is one of the militants that was killed. there are strong indications from the yemeni sources that they believe if it wasn't him, another saudi high value target from amongst the leadership was killed in those strikes. this is significant because as you mentioned, this is somebody who has had his fingerprints on virtually every major plot. every major plot that's been hatched out of yemen the past five, six, seven years, including the underwear bomber

plot, including also the cargo plane bomb plot from october 2010, and also a plot to try to assassinate a senior level saudi official in saudi arabia also in 2009. he's seen as a real threat and somebody that the u.s. and yemen has been wanting to get for quite some time. the question is even if they have gotten him, will that degrade the capabilities and most of the yemenis i speak to don't think so. that's why the operation is massive. they are going after training centers. they are going after hideouts. you have yemeni boots on the ground going into parts of that country they have not dared go into before because yemen has a weak central government and some say a weak military and they don't dare venture into hot beds where aqap has a working structure. yemen is a rugged country where there are plenty of places to

hide out. it's that dangerous even with a military escort. u.s. and yemen striking hard and fast. they say these operations are ongoing. they are trying to take out top tier leadership but they are also more importantly trying to degrade the capabilities of aqap which is the most dangerous wing, most threatening wing of the al qaeda network in the entire world. >> mohammad jamjoom, thanks so much. still to come, the critical minutes that may have doomed that sinking ferry off south korea. training can mean the difference between life and death. good morning. >> good morning, carol. we are in a full bridge simulator right now. we're exiting the port of miami. once we get into the waters, we're going to show you how complicated we can do an exercise and all of that after the break. sfx: car unlock beep.

it's a busy morning of developments in the tragedy of that crowded ferry that sank off of south korea's coast. divers say they have found no air pockets in the submerged hull dashing hopes of survivors. 156 people now confirmed dead. 146 still missing. there have been two more arrests and failures in handling the crisis. criminal charges have been filed against the captain and ten crew members now. the criminal charges hinge on one critical presumption. the captain and crew were entrusted to respond quickly to an onboard disaster. we're about to walk through some of the training for ship going

emergencies. she's in a bridge simulator in ft. lauderdale. good morning. >> reporter: good morning. we're at resolve maritime academy. what you're looking at is a bridge and dave bolt is here to tell us what this is. what are we looking at? >> this is a full mission bridge simulator. it's what you would see on the bridge of a modern ship. >> there's a lot of things we can do here. let's start listing slowly to get perspective as to what this looks like. at this point if you're on the bridge, you would be concerned? >> i would be concerned if you are stuck at this point and not rolling back. you would know there's a problem. >> we have a very rare look as to with a could happen below deck. take a look. on a ship, this is the universal sign of trouble. inside this model ship hull, instructors from result maritime academy train crew how to prevent a deadly disaster at

sea. like the sinking of the passenger ferry in south korea. investigators say the nearly 7,000-ton ship sank in about 2 1/2 hours. 476 people were inside when a boy onboard made the first call for help at 8:52 a.m. local time. the ship's crew made a distress call about three minutes later at 8:55. the crew's response is critical to preventing disaster. in this scenario, water is rushing in from an unknown source. water is starting to rise. what do you do? >> main thing is to get away from the damage. get outside. let the crew know if you did find damage and make sure the crew knows about it. >> reporter: they use anything they can to plug the holes. how much time do you really have to get out or to assess the situation when water really starts just gushing in?

>> it all depends on the scenario. how deep the hole is in the water. the deeper, the more water pressure pushing in. >> reporter: if i'm a passenger on the ship and i'm not familiar with the ship, what do you suggest i do to get to safety? >> best thing to get to safety is follow the walls. get to a ladder. get outside. i always recommend getting to the main deck. >> reporter: here we're going to be able to do this list just one more time because we want to show you the perspective. start doing that slowly. you can see it here from the bridge. we're going to give you perspective as to what passengers perhaps would be looking at. take a look at our second camera. this will really give you a sense if you're a passenger, you can see life boats and how close the water is to the life boats there. i've got to ask you. in this particular case if a ship is listing at this angle

and it's a ferry ship, if it's carrying cargo or carrying cars, what other complications could you see? >> with any cargo there's always a problem the cargo may shift. that's the same in aviation and shipping. obviously if the cars are strapped down and in place and everything is okay. if you get to a certain angle and they start moving, it can further complicate stability issues. >> a lot of different complications, carol. >> i would like to ask dave a question about getting out of a ship in distress because in the south korean incident, kids were told to stay on a ship. if i'm on a ship and i know it's possibly sinking, what should i do? i know the other guy says feel around the walls and get outside but the ship is totally dark. you're unfamiliar with the ship. you may not know your way. what should you do for your own safety before that ship leaves the dock? >> well, i would say just like

getting on an airplane, they recommend counting how many seats to an exit. it you are getting on a ship or ferry or cruise ship, not a bad idea to have an idea of your surroundings and have some personal responsibility that way as well. >> reporter: one of the things that pete you saw in the piece also told me is it's so important for you to figure out exits and for you to be familiar with the ship or plane or whichever vessel you are in to make sure that you know how to exit in case of an emergency and to take those drills very seriously. he says a lot of times people ignore them. in cases like this, extremely important. >> if an announcement came over the intercom on a ship, i would probably obey the command to stay onboard. at what point should you not? that's the scary part. you depend on the crew to tell you what to do and in this case apparently the crew told these kids the wrong thing. >> yeah. i don't know the details of this

case but in general on passenger ships you drill for this kind of thing. every crew member has a specific job. so you have crew members in stairways and alleyways directing passengers toward the boat deck, toward the life boats and life rafts. >> the best thing is to know where the exits are. to know how to get up on the deck. to know where life jackets are. to know where life boats are and sort of take matters into your own hands if need be. and hope you have a great crew, right? >> if need be, there's a lot of signage and directions. you should know where you are and what your escape route is. >> reporter: a lot of times you have to follow your gut and even if it's inconvenience to go to the upper deck to put that life jacket on, you can go back if it's not an emergency. go back to your room afterwards. an inconvenience but it could save a life. >> absolutely. >> thanks so much. we'll be right back. the convers car loan didn't start here. it started with that overdue bill he never got.

we're learning more about why a teenager stowed away in the wheel well of a plane. he's now recovering at a hospital in hawaii. his family in seclusion back in california. dan simon is in san jose. this boy wanted to see his mom? >> reporter: to put it simply, it sounds like he was homesick. what we understand is he told fbi investigators in hawaii that he wanted to go to somalia and see his mom. he told classmates here in santa

clara, california, at the high school that he was from africa and he wanted to live here. that may give you some insight into his state of mind. why he chose a hawaiian airline specifically, apparently he didn't choose them. it was just the first plane he saw according to the fbi. in terms of the time line of all this, we're getting new information. what we're told is that he hopped the fence here at the san jose airport at approximately 1:00 a.m. sunday morning. keep in mind, the plane didn't take off until 8:00 a.m. that means he would have been on the tarmac or in that wheel well for seven hours before it even took off. that raises even more questions as to how he went undetected for so long. >> i want to focus more on this 15-year-old boy. his family in california, are they with him? >> reporter: we don't know where they are. we've been knocking on the door at their home and we're not getting an answer. what we understand is that he is still in the hospital, the boy

is, he's in stable condition. he's apparently doing okay. at a certain point child welfare officials in hawaii are going to make arrangements for him to come to california and that's if his parents aren't with him in hawaii. >> now to security at the san jose international airport. this teenage boy jumped the fence at 1:00 a.m. and spent seven hours on the airport grounds and nobody really noticed. any improvements under way at the airport? >> reporter: not yet. you know, what the airport director has said is that nothing is foolproof. certainly proves the point in this particular case. he seemed to have hopped a fence that was six feet tall and had barbed wire on it. they'll have to look at the perimeter at this airport and airports across the country because as this teenager has proven, it seems something that you can do with relative ease, carol. >> dan simon reporting live from california this morning. thank you. still to come in the

is more than symbolism, u.s. troops are heading to -- they're already there. u.s. troops are in poland and three other nations along the baltic sea in a move the united states says is in direct response to the crisis in ukraine. for its part, russia is also mobilizing its military with previously unplanned drills. back in ukraine, pro-russian forces are now a target as the government renews its call for anti-terrorism efforts as a bid to eliminate militants in four key cities. i want to bring in barbara starr to talk more about u.s. troops in poland. we have pictures of them now. tell us more, barbara. >> these are u.s. troops from the 173rd airborne brigade based out of italy that this morning landed in poland for joint training with polish military trips, airborne paratrooper

training. that's what they will do in poland. similar deployment of u.s. troops from europe to lithuania and estonia. all of this as you see the troops there is part of an effort by the united states, 600 troops in four countries, to have what they're calling a persistent presence in eastern europe. this is all about sending a message to russia about ukraine but also very much stepping up the training in eastern europe to reassure nervous allies there who look across their boarder at russia and get concerned about what the russians may be up to next. hard to believe in this day in age but that's what's actually going on in europe right now. worries that moscow could expand its operations and have its eye on these other countries. so stepping up the so-called rotational presence of u.s. troops in europe. they'll there be for about 30 days in all of these locations and then other u.s. troops will

rotate in. nato will try to get an agreement to send its own troops in. all of this about keeping presence facing russia. not about combat. training presence. that's what they're saying, carol. >> training presence. but more. sending a message to russia too, right? >> exactly. >> barbara starr reporting live from the pentagon. let's bring in congressman peter king of new york. he joins me now. good morning, congressman. >> good morning, carol. >> thank you for being here. your reaction to these u.s. troops in poland and those other baltic nations? >> i think it's very important that the president do this. we should have them in poland and make it clear this is not just a temporary measure. one criticism i would have of the president is he's not up until now shown we're in this for the long haul. we have to make it clear that our troops should be there. also i think we should consider restarting the missile defense

system in eastern europe, which again will be a signal to the russians and also we have to dramatically accelerate, i believe, the production and exporting of liquified natural gas to europe so the allies won't be dependent on russia. it will be a strong symbol to russia and investors in russia that we're serious about this. >> there are 40,000 russian troops along the border with ukraine. some suggested the united states should send more troops to eastern europe. do you agree with that? >> i don't know if we have to at this stage. i think right now this is sending a first signal. if we have to send more, we should. the purpose of our troops is not to counter the russians per se man for man or soldier to soldier but send a signal that we're standing with our nato allies and any movement by the russians against a nato ally is a move against the united states. so in many ways our troops there are a trip wire. the russians have to realize

that a move against poland, for instance is, a move against the u.s. and nato would come to the defense of one of those countries. >> we're at a standoff. it's unsettling to see u.s. troops there even though there is no interest in any military action per se. >> well, again, nato to be taken seriously we have to show that we are serious about defending these countries. we do live in a very dangerous world. vladimir putin has changed the calculus in that part of the world. there would be societal links between us and the russia and russia would become more westernized but putin wants to apparently rebuild a russian empire so we have to be serious about this. nato just can't be there for decorations or for parades. it has to show that it is

willing to stand and fight if it has to. nobody wants that to happen. one way to invite aggression is that we show any sign of weakness and we show we're not going to stand by our allies especially the baltic states. some of those baltic states have 25%, 30%, 35% russian population. that's a good excuse for russians to say they have to go in to protect the russians in those countries. we have to make it clear that we won't tolerate that. >> is it safe to say then that you don't think the tougher sanctions is the answer and we shouldn't bother with them? >> oh no. i think we have to do sanctions and increase sanctions. we should -- this has to be a full comprehensive plan against the russians. sanctions are important. we should get people closest to putin and make it clear to other countries that want to invest in russia that this will be a long economic struggle, military standoff if you will and we are very serious and we'll be

increasing our exporting of energy to europe which then weakens the russians because they won't have the markets in europe they had before and european countries won't depend on them. it's similar to 1946 when winston churchill realized there would be a struggle with the soviet union. this has to be an all-out diplomatic and economic struggle with military in reserve which is why we have training maneuvers going on in poland. training means you train to be ready for combat if that happens. that's why the troops are there. >> seems like deja vu all over again. congressman peter king, thank you so much for joining me this morning. i appreciate it. >> very welcome, carol. still to come in the "newsroom," reports of an object of interest found in the search for flight 370. and the formation of an international investigation team. what does that mean for the search?

asked about it a few hours ago at a press conference, they said they are aware of this potential debris but that it hasn't been verified so they can't really comment on it at the moment. they also added that none of the debris that's been found so far has been related to mh370. we may know in the next few days once the australian officials have a chance to figure out what exactly this debris is. carol? >> a piece of metal washed up onshore in western australia. investigators are looking at it. hopefully we'll have answers soon. an international team is in place. any word about that? >> reporter: that's right. no clarity at the moment on exactly who will be in that team. we know it will be compromised of international and local experts and the main purpose of this team is to figure out what

happened to mh370 so this kind of incident really doesn't happen again and the significance of this is really the malaysians trying to show they're trying to be as transparent as possible as the acting transport minister said it's important to have a strong, competent, transparent and highly credible independent team because the whole world is watching and malaysia according to the malaysian authorities has nothing to hide. this is a way of really showing that they are trying to be as transparent as possible. >> thank you so much. still to come in the "newsroom," searching for the victims of the south korean ferry disaster. we'll show you the high-tech underwater rover that could help rescue teams search that sunken vessel. on in europe. someone stole her identity and opened some credit cards in her name.

[ male announcer ] don't stop taking eliquis unless your doctor tells you to, as stopping increases your risk of having a stroke. eliquis can cause serious, and in rare cases, fatal bleeding. don't take eliquis if you have an artificial heart valve or abnormal bleeding. while taking eliquis you may bruise more easily

and it may take longer than usual for any bleeding to stop. seek immediate medical care for sudden signs of bleeding like unusual bruising. eliquis may increase your bleeding risk if you take certain medicines. tell your doctor about all planned medical or dental procedures. those three important reasons are why i'm shooting for something better. eliquis.

sunken ferry including latest underwater technology. one tool . >> reporter: if you wonder how robots might help search for passengers, watch this. you're looking at a remotely operated vehicle snaking its way around a sunken shrimp boat off the coast of gloucester, massachusetts. when it comes to ship wrecks, this machine is a workhorse. it maneuvers its way through tiny openings where human divers to fit or it's too dangerous for them to go. >> to go forward you'll use forward. it's very intuitive. very user friendly. to back it up, you'll back up this way. >> reporter: it's like a video

game. >> exactly. >> reporter: robin is a pilot and diving expert. she works for the company is that builds these. it's directed by a pilot at the surface. it moves at two knots per hour. even in murky water or at night, these robots can see. they have lights and special low visibility cameras. and if that's not enough, they have sonar too, which can pick up images up to 400 feet away and feed them back in realtime. >> you can see the stern of the vessel. you can see how that is the back of the boat is that square shape. that's 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 the knob back to return it to the surface. whenever this mini rov is used, it's lowered into the water by a rope line that you see there. here in the water that we're on, it's only about 20 feet deep or so. if this were going to be

deployed to search inside the seawall ferry, this wouldn't be a problem because it work in water as deep as 1,000 feet. divers can only go down 130 feet safely. and these robots, they can swim upward inside a ship too just as divers in south korea are doing to reach the cafeteria and areas on the upper floors of the doomed ferry. if you want to get to a higher level on a ship or ferry, could the mini rov actually climb? >> they would have to have a really good idea of the blueprint of the vessel because it can be very disconcerting in something like that where it's flipped. stairs where would you be on the bottom will be over your head. >> reporter: if anyone is found, the mini rov is equipped with a grabber strong enough to pull a
