sevastopol. the answer to our question was d. the united states ranked 66th, sort of in the middle. thanks to all of you for being part of my program this week. i will see you next week. hello, everyone. i'm fredricka whitfield. the search area is expanding in the indian ocean for missing malaysia flight 370. this, as the search moves into day 38. also, we're following breaking news in ukraine where violence and tensions are quickly escalating. here you're about to see masked men pinning a man against the wall. this is in a town only about 100 miles from ukraine's border with russia. keep in mind, this is happening just a month after crime voted to secede from ukraine and join russia, a move the rest of the world has not recognized.

[ gunfire ] it's also where the masked men took over the police headquarters. this video is all new in to the "cnn newsroom." security forces have said that they will but they saw no signs of a large ukrainian force. and this video just in this afternoon. it's social media video that reportedly shows pro-ukraine protesters beaten and bloody. cnn cannot authenticate the video. let's take you to nick paton walsh. the situation is very volatile right now. what is the government's response to all of this violence? >> reporter: well, we've seen a

really troubling violence. an amnesty who is willing to lay down their arms by 9:00 tomorrow morning local time but also the promise of military intervention to stop what they call terrorist actions here. >> translator: we did everything to avoid human victims but we are ready to give an answer to all attempts at invasion, destabilization and the council took the decision with the participation of the armed forces of ukraine. we won't let russia repeat the scenario in the eastern region of ukraine. for those who didn't shoot our soldiers by monday, i signed a decree to guarantee they will not receive any punishment for their actions. >> reporter: well, in that speech, too, there was the offer of decentralization, which is a

bit of what they really want, and it's deeply frustrating. we've been going round. the cities that we've been referring to almost around where i'm standing it seems police stations are voting for pro-russian militants at first and then to occupy the buildings. the ukrainian security forces say based on the launched and didn't get past the out skirts of the town. video showing in fact from social media that the apc sent in the personnel and they were in a gun exchange outside of the towns. then they explained in a decision to pass any future operations to military here but the real question lurking is can ukraine muster enough force to resist these pro-russia

militants and if they decide that they are able to do that, what is the response from russia? he has said that they must stop creating war against its own people. some of the pro-russian supporters are having their rights refused. >> nick paton walsh, thank you so much. what is the obama administration saying about the latest moves in ukraine? here is u.n. ambassador susan power on abc's "this week." >> it has all of the telltale signs that we saw in crime. there's nothing grassroots seeming about it. if actions like what we've seen continue, you're going to see a mp ramping up of those sanctions.

>> the white house says, quote, the vice president will underscore the united states' strong support for united democratic ukraine that makes its own choices about its future path. >> the search area for missing flight 370 is now getting bigger after days of shrinking. today officials say crews were searching a 22,000 square mile area in the indian ocean. that's expanded 40% from yesterday's search area. the big focus is still trying to find the pings that crews heard last week which are consistent with a plane's black box. well, nothing credible has been heard since tuesday. will ripley is following every surge in perth. what's the latest on the efforts today and why is the search area being expanded? >> reporter: yes, as you mentioned, we're on day 38 here

and planes will be taking off shortly. the reason the visual search area has expanded, they continue to refine this data. they are looking at the currents and analyzing where they think the debris field may have floated from the time they think the plane went into the indian ocean until now. keep in mind, it's a moving target. these are -- this is debris that would be affected by weather conditions, by the currents, and really it's a guess. it's an educated guess as to where this might be. the planes continue to search one area, don't find anything, they move on to the next. that's the visual search happening and what has gotten so much attention, especially over the last week, is the underwater search where we have the u.s. navy's listening device, the towed pinger locator behind the australian ship. we have australian air force jets that are dropping the sonobuoys and then we have a british ship in that area listening. all of them trying to see if there is any more ping to be

heard from the in-flight data recorders. we have four pings. two they believe was coming from some sort of black box and the data analysis on the other two pings is still pending. those pings were much weaker. at some point soon, fred, the decision is going to have to be made, what are we going to do? are we going to switch this search? in other words, are search crews going to start deploying the underwater submersible with side scan sonar? once they decide to do that, this whole process becomes even slower and more grueling than it already is. >> thank you so much. will ripley, thank you. we'll talk more about that later on in the hour. so up next, more on flight 370. i'll bring in our panel and ask them if they think is a big step backwards in the search for the 777.

could save you fifteen percent or more on car insurance.s everybody knows that. well, did you know bad news doesn't always travel fast? (clears throat) hi mister tompkins. todd? you're fired. well, gotta run. geico. fifteen minutes could save you fifteen percent or more.

all right. searchers for flight 370 are once again looking in an expanded area after more study of ocean currents and other data, the search area is now some 40% larger than it was yesterday. so is this a case of taking two steps back in the search for the plane? let's go now to our panel at this hour. bob francis is the former vice chairman of the ntsb, cnn aviation analyst mary skchiavo represents families in airline disasters. and andrew carr is president of underwater search and survey. okay. so more study of currents and data has led them to expand the search area to about 22,000 square miles. what does this mean to you, bob? is this a setback or is this encouraging? >> i think it's encouraging.

>> why? >> well, because they are clearly getting more and more confidence in the equipment that they are using to try to pin down where the aircraft went in. so they are more comfortable with what they have now. the fact that it is larger than what it was before, that just means that obviously they are more confident in the accuracy of that and it's progress. >> for those of us not in the business of this aviation expertise as all of you are, i think most of us would think that to triangulate and search the area of the field, that would be the direction that these searchers would want to go. why is this to boost the confidence to expand the area, to make it bigger? >> well, i also think that, you know, the pinger batteries have undoubtedly stopped at this

point so what they have from under the water is all they have and i suspect that they were also going to take sort of one last effort and really do an extra push and probably push the envelope on the search area to see if just by any chance they couldn't expand the area and maybe hopefully see some wreckage before they start with those bluefins under water because at that point there would be no more searching for pings and that would mean a very long underwater search or not, if they get lucky. let's go out there and comb it once more for that wreckage. >> arnold, it would seem that because there has not been a ping in now five days, that clearly the batteries must be dead and perhaps there isn't going to be this pinging sound. why not just go ahead and put in the bluefins? >> i would think that they are trying a little harder.

the batteries weaken. they don't stop abruptly. so if you can bring a vehicle or a probe down close, you can see it when you get much closer, maybe a kilometer or two away and then, of course, it's going to gradually turn to nothing. i have one comment, though, on the search area, i was concerned about the expanding search area but as far as i understand, that's for debris on the sea surface and it's a good thing to do. you really need verification. right now it's almost like dealing with a third party, the ping. and surface debris hindcast through good oceanography and meterology will help the search area. >> when you talk about the aerial searches because of drift, if there is to be debris, you're saying it would have

traveled further and that helped justify this 22,000 square-mile area? >> yes. that's as i understand it. and frankly, the debris usually is at the sea surface from the event where the aircraft meets the water and then after that little unknown debris would come to the surface. you really have to expand the area to look at the conditions. >> mary, as we enter a new search week and we're entering week five now of this area, what do you want to see happen in this week? what kind of assets do you believe it's time to get at the ready to take this search to another level? >> well, i think at this point -- >> go ahead. >> i think that they are undoubtedly ready for the underwater search because if the batteries on the pingers are really dead, then there's

nothing more to be gained once they assure themselves that that has happened and they will be readying for the underwater party. we've heard about them getting a logistic ship from the united states to help support the mission. that could be slow going. it's going to take a long time just to get the submersibles deployed. they have to bring them back up and unload the data. it's going to be slow going. the fastest that they can go, i understand, is 40 you miles a day. this is going to be much slower because they have to pick their way through the great depth and try to get clear pictures. so i think they are getting ready for that. i would be surprised if that is what takes place this week. >> bob, what do you want to see this week? >> i certainly want to see them proceeding with that. i also hope that throughout all of this we won't lose sight of the import of moving to new technologies that will allow us to avoid what we are going through now and what we went through with air france and to

be able to have the aircraft downloading through satellites what is going on on either a periodic basis or when there is a problem. that won't apply to all aircraft. it will apply only to aircraft presumably that are doing entrance ocean yan nick flights. but i hope that the media see of the search that is going on does not divert us from the import of making sure this doesn't happen again. >> arnold, do you see this week as a potential turning point, meaning, the readying of new devices that will be employed to help with this search? >> yes. it's really coming time to launch the underwater vehicle, the unmanned underwater vehicle and set up a severarch pattern. before they do that, they have to set up waypoints with

hydrophones located so it can mow the lawn and really track prescribed areas of high priority. >> all right, arnold, bob, mary, thank you so much. i'll check back with you later on in this hour. and we'll have much more on this mystery surrounding flight 370. first, a fast-moving wildfire in chile destroys hundreds of homes. and oscar pistorius is expected ba expected back on the stand in his murder trial this week. co: sometimes you don't know you need a hotel room

until you're sure you do. bartender: thanks, captain obvious. co: which is why i put the hotels.com mobile app on my mobile phone. anyone need a coupon? i don't.

well get back to the mystery surrounding flight 370 in a moment. first, other news. here's nick val leencia. >> the ntsb is investigating the cause between a bus and fedex truck. officials say blood samples from both drivers could provide information about whether drugs or alcohols may have been in their systems. south africa, monday, marks week six in the oscar pistorius

trial and the sixth day of pistorius testifying. he points to whether steenkamp was heard screaming before she was killed. in chile, at least 11 people have died as fast-moving wildfires continue to spread there. more than 1200 wildfires have battling the fires. authorities call it one of the worst fires in the country's history. and more cruise passengers are getting sick. more than 120 people have come down with an illness. the cdc is trying to figure out what caused it. meanwhile, another ship, princess "crowned princess" was

hit by illness. more than 150 people got sick before it returned to port yesterday. there has been a new report issued on climate change. it says it may not be too late to stop the consequences of global warming. governments will have to act quickly and aggressively to cut the greenhouse gas emissions. tuesday marks one year since the boston marathon bombings. as the city prepares for the big race on april 21st, they have joined together to make sure that they are boston strong. fans are invited to come to the site. one photo will be selected as the next week's issue. 9,000 more runners this year

than last year. a lot of people affected there in boston by the bombing. even if they weren't on the finish line. the community was shut down for so long. >> absolutely. and that big picture, that brought together a lot of people, people who traditionally go to the races, a lot ofress departments, first responders as well wearing blue and yellow, which are colors of the boston marathon. it was a nice moment, a real prelude to what will be a really touching and bittersweet kind of anniversary this coming tuesday. thanks, nick. >> you got it. still trying to get answers on the missing plane and it's been an increasingly difficult task. >> you don't have to push. >> tensions with malaysian officials are reaching a boiling point. what questions they don't want to answer. next. gunderman group is a go.

yes! not just a start up. an upstart. gotta get going. gotta be good. good? good. growth is the goal. how do we do that? i talked to ups. they'll help us out. new technology. smart advice. we focus on the business and they take care of the logistics. ups? good going. we get good. that's great. great. great. great. great. great. great. great. great. (all) great! i love logistics.

how much money do you think you'll need when you retire? then we gave each person a ribbon to show how many years that amount might last. i was trying to, like, pull it a little further. [ woman ] got me to 70 years old. i'm going to have to rethink this thing. it's hard to imagine how much we'll need for a retirement that could last 30 years or more. so maybe we need to approach things differently, if we want to be ready for a longer retirement. ♪ ♪ ♪ [ female announcer ] with five perfectly sweetened whole grains... you can't help but see the good.

hello again. i'm fredricka whitfield. search crews are combing through an expanded area. the red boxes on this map you're about to see shows the visual search area today and all of the gray spots are where crews have already searched. the one shred of evidence, the four pings consistent with black boxes haven't been heard since tuesday. this whole mystery has led to more questions than answers and the malaysian government has been unable to release any more details. nick robertson gives his firsthand account between officials and journalists. >> reporter: mr. minister, how

are you? >> i'm happy to see you later. i'm just doing my walk about. >> reporter: we've requested an interview many times. with that, the man heading the hunt for missing flight 370 is off. the defense minister and acting transport minister is hosting an international arms fair. from helicopters to tanks to guns. reporters invited along. some questions apparently not so welcome. you don't have to push. as his tour continues, his aides advise us to wait for his press conference. that's good, because the question just refused to answer, when they told civilians they picked up flight 370 on their radar, is a contested question. precisely when did the military inform the department of civil aviation about what they saw on the radar? >> i said earlier --

>> reporter: no answer, then. he doesn't want flight 370 questions. buts a the conference continues, it turns out some flight 370 questions are okay. >> tell us, are you any closer to deciding who will extract the data from the black box? >> yes, we are getting closer to that issue. the attorney general in the uk is discussing exactly that. >> two days ago you said even the passengers were under investigation but a week ago the ig of the police said passengers cleared from the investigation. which is it? >> let me clarify. unless we find more information, specifically on data in the black box, i don't think any chief of police will be in a position to say that they are cleared. >> reporter: are you in a position to rule out terrorism? >> we can have a separate session with cnn later. >> reporter: questions still waiting to be answered. nic robertson, kuala lumpur,

malaysia. >> thanks, nic. let's bring back the panel, bob francis, mary schiavo and robert carr. is this a case of internal agencies not working together or is it that it's an unusual set of circumstances and not everyone is communicating at their best? bob, you first. >> well, i think the malaysian performance since the beginning has been -- has been very, very unfortunate and weak. one of the things i was thinking about today is i wonder how specifically they have worked with the french after the air france accident or the u.s. after the swiss air accident and really talked to them in a meaningful way.

i know that there is an ntsb group out in kuala lumpur and i would wonder, given the way that the malaysians are acting, whether they are benefiting from that as much as they might. >> so mary, is there a way in which the malaysian authorities can recover from this? because certainly it's been very messy at the beginning and i guess it could only worsen but at what point and how can they recover from this since there are still no clear answers about anything -- the circumstances of this flight? >> i think the best thing they can do at this point is appoint the task force to lead the investigation further even after recovery of the black boxes because when did the military tell them that they had information? when did they have the inmarsat

data and tell the world to stop dating in the south china sea? there are so many disconnects here that i think their credibility was shot but also leads me to believe that they have internal governor mental problems which will probably cloud the investigation. for example, there's something weird about this radar and the refusal to say what it is and the only thing they will say is they lost contact with the plane for 125 miles. where there is smoke, there is fire. there is something wrong with the radar data. >> and so arnold, does this make you even more worried about any data that could be collected? say a black box or any kind of debris is collected. do you worry about whether they can handle, whether they can secure any data if it comes to that? to you, arnold.

>> the same question? >> well, this question is really about trusting malaysian authorities as to if there is any data, any evidence that is collecting, whether it's the black boxes or it becomes debris, ultimately it may make its way to malaysia. do you worry whether authorities have the capacity to secure this type of evidence or data? handle it? >> i think the real important thing is to have multiple representatives in the retrieval process right from where it breaks the surface on to the craft and then transporting it to respected authority on really recording recorders and processing the recorders. two of the best, as i think it has been said, the uk and the united states nstb. you really need more than one person with the recorders every

moment. >> mary, do you have any worries in that area? if these agencies can't seem to get together, as you just underscored, then what happens if there is hardcore evidence coming from the collection of evidence or material from this search in the indian ocean? >> well, the best thing is to have more than one set of eyes, more than one country on it. if you're suspect about the handling of the investigation, which the world is certainly suspect about the ability of the malaysians and not picking on them. they have said it themselves, they are not able to do this black box data. the best thing to do is to keep a consortium of individuals working on it. the u.s., france, they can all do it. australia can do it and then you don't have the investigation corrupted by claims of self-interests, like the malaysians, because it's a government airline, et cetera.

i think the consortium is the way to go. >> bob, with the missteps or mixed messages, do you think that investigators need to return to some of the initial theories? might this plane not be in the indian ocean? could it be that the trajectory that we were given by authorities is incorrect? might it have gone a different direction? do you think it's time to revisit any of those theorys? >> i would assume these theories are under constant study as the focus continues in the ocean. and one of the things that i think is important to remember here, presumably this investigation is being done using the party system which is ikao and it's very clear who are parties to the investigation.

the country of registry, the country of manufacturer, et cetera, et cetera. so unless the malaysians decide to ignore the party system and there were some indications early on that they were doing that, but certainly everyone that is responsible in this investigation has to make sure that the appropriate and designated parties to this investigation all are -- have access to all of the information as it comes in. >> bob, mary, arnold, thank you so much. we'll check back with you momentarily. all right. so what do we know about the captain of flight 370? next, some revealing clues from social media.

intensifies, so do questions about the pilot. what kind of person was he? some answers can be found in social media. >> reporter: good night malaysia 370, those last few words spoken by the captain of the plane, zaharie ahmad shah, bringing the 53-year-old pilot's background in focus.

>> hi, everybody. this is a youtube video that i made. >> reporter: of all the mysteries surrounding the disappearance of 370, a distinct image of the captain emerges on social media. in this 16-minute video, zaharie explains how to optimize an air conditioner to reduce electricity bills. his faceback page full of images of spruced up gadgets indulge in his passion. a photo of what appears to be his much talked about his flight simulator. there are dozens of pictures of model helicopters and planes. at least until about a year ago, his facebook posts show that zaharie was passionate about politics, urging people to vote out the current government, referring to the ruling coalition, he writes, 50 years in power by a single party does not say much about democracy in the country. he's known to be a supporter of

the opposition party's ibrahim but what stands out most is his love for food and cooking, from flat noodles to curry, he appears happy. his posts trail off around the fall of 2013. his last post, january 3rd, 2014. a pilot with more than 35 years of experience, passion for the job and some interesting hobbies but nothing in the social media posts appear to suggest foul play. most of the captain's friends we spoke to say he was a very kind and humble man. they don't believe that he could have done anything to hurt anybody. >> so if there seems to be nothing that suggests foul play, why the intense scrutiny about his background? >> reporter: well, investigators are really investigating all aspects right now. officials say somebody

deliberately turned that plane, steered ta plane towards the wrong direction, made that sharp turn and around indonesia to avoid radar. whoever that somebody was had to be an experienced pilot. so we've seen since the beginning investigators going to his house, examining his flight simulator, talking to his family, talking to this friends. but it's not just the pilot, really. the investigators are looking into all possibilities right now. the acting transport minister here saying that nobody has been cleared from the investigation. none of the passengers, none of the crew members, and the malaysian police chief has said, i've already questioned 205 people so far related to those on board the flight and also the crew members, fredricka. >> what's the latest from family members? what are they saying about him and the continued suspicions? >> well, the response there has

been pretty much consistent all along. they say they don't want to believe anything until they actually see some sort of evidence, some sort of proof. they are holding on to hope and that's been consistent, fredricka, all along. >> all right. sumnima, thank you so much. we're going to shift gears quite a bit now. because guess what, tonight is premier night with anthony bourdain followed by morgan spurlock. what is it like chases celebrities with the camera? a preview, next. gunderman group. gunderman group is growing. getting in a groove. growth is gratifying. goal is to grow. gotta get greater growth. growth? growth. i just talked to ups. they've got a lot of great ideas.

like smart pick ups. they'll only show up when you print a label and it's automatic. we save time and money. time? money? time and money. awesome. awesome! awesome! awesome! awesome! awesome! awesome! awesome! (all) awesome! i love logistics.

the season premier of anthony bourdains emmy winning "parts punjab's cuisine. here is a preview also of morgan spurlock's "inside man." >> kim kardashian is flying in from paris. >> being a photographer is a real skill. it's a skill that i don't really have. i did not get great shots. >> it's like you're these little guys who are running and chasing down whether they are at the airport or outside someone's house. it's like a little school of

piranhas that are going around to feed and then you go off to something else. a lot of them get a bad rap. there are some who are good guys and have families and just doing this to make a living who have a real code of ethics who say i'm not going to take a picture of somebody's kid because i've got a kid and then others will say, no, that's what i want. they have no qualms about doing the most ridiculous or disgusting things to make a buck. >> ever feel bad for doing what you do? >> if i felt bad for what i did, i wouldn't do it. >> the big takeaway for me is the culture. they are the ones who are more responsible because they are the ones who put the bounty on the photographs and the bounty on the celebrities and they establish the price of what they are going to pay for these pictures so i think the paps are there to make a buck and if you say we'll give you 10,000, $15,000 for this photograph, guys are going to chase and do

everything that they can to get the photograph. so i think those guys, do they put themselves in situations that are dangerous? of course they do. but i think the magazines are the bigger problem. >> again, that's tonight at 10:00. now, what will it take to find that plane? we'll show you the latest tool that will be deployed. first, fred pleitgen takes us on a tour. >> reporter: when i was taken on a tour, it seems there was a memory on every corner. >> this was the home that i was born. that was my candy store, before and after school. that's my kindergarten. these are the original courts. i want to show you my very first

coach. when i was little, my parents were too busy and i wasn't allowed to go on the court, that's where i played for hours. it's a city square. >> here we are. >> standing on the famous terrace. it looked so much bigger then. >> beer and sausage. (dad) well, we've been thinking about it and we're just not sure.

(agent) i understand. (dad) we've never sold a house before. (agent) i'll walk you guys through every step. (dad) so if we sell, do you think we can swing it? (agent) i have the numbers right here and based on the comps that i've found, the timing is perfect.

...there's a lot of buyers for a house like yours. (dad) that's good to know. (mom) i'm so excited.

manpower to find that missing malaysian jet but it just might be a certain machine that discovers any wreckage. we're talking about autonomous underwater vehicles, commonly called auvs. we're in fall river, massachusetts, to explain how they work and what they do. rosa? >> reporter: fred, i'm inside a lab that belongs to ocean server, a company that manufacturers auvs. you can see them all around me. take a close look. this device has thousands of little pieces but one main

purpose. and that is to find debris in the ocean floor. this probe is the latest technology that could be used to find flight mh-370. using side scan sonar, it searches for things that don't belong beneath the sea. >> side scan sonar is an acoustic technology that's based on reflections of sound rather than reflections of light. >> reporter: the autonomous underwater vehicle, auv, is creating a map of the sea floor. this time it's the bottom of a massachusetts reservoir but it could be the depths of the indian ocean. >> it's an electronics package that is inside the vehicle. it's basically a computer that processes the data to make the pulse and to bring back the pulse and configure it into an image. >> reporter: it moves back and forth along the surface but some

auvs can dive deep into the ocean. sonar helps identify and find debris, like the submerged car. >> once we identify the target, we did this crosspattern and if we zoom in here, we pull in that sonar file and got a better high-def image of that car. >> in the case of flight 370, it could stretch this entire obstacle out for months or years. to get a real-time close-up i am manua image, this rov uses a map to visit the location. >> that's great. >> it's pretty choppy out here today so the visibility is quite reduced. >> reporter: in the depths of the indian ocean, you would probably use sonar at first, i imagine, if the water is very deep and very dark. >> yes. >> and then perhaps the camera? >> exactly. >> reporter: once it is there, it uses a camera and claws to

pick up debris. bringing critical evidence and hopefully answers to the surface. here's what is fascinating about this technology. whether it's this auv, which is for shallow water or for deep water like the one in the indian ocean, it uses side scan sonar and the process of retrieving that information is the same. it creates a map of the ocean floor. fred? >> thank you so much, rosa flores. appreciate that. hello again, everyone. i'm fredricka whitfield. we're watching two big stories. the search area section panding in the search for flight 370 as we move into day 38. also, we're following breaking news in ukraine where violence and tensions are quickly escalating. you are about to see masked men pinning a man against the wall. this is only about 100 miles from ukraine's border w
