"newsroom" starts now. happening now in the "newsroom" breaking this morning malaysian authorities asking the united states for more military assets to find flight 370. as families demand answers. >> we will continue searching and we will keep investigating and will never give up. >> this morning the ocean shield heads out to sea in hopes of finding debris as cnn sits down

with australia's prime minister. >> this is a very, very difficult task but nevertheless we're giving it the very best shot we can. and if anyone can find this aircraft, it's us. >> how long can this be sustained realistically? >> the effort is ramping up. not winding down. >> but it's now a race against the clock as the battery life fades on those black boxes. >> both of those devices have been emitting a ping for several weeks. we believe they only have about a week of battery life left >> you're live in the cnn "newsroom". good morning. i'm carol costello. thank you so much for joining me this morning. the search intensifies for malaysian airlines flight 370. ten planes and 11 ships scour the southern indian ocean for debris. malaysian officials confirm the most promising lead those four

orange objects found over the weekend nothing more than fishing equipment. this is malaysian motors calling on the united states to deploy more military assets to the search zones. australia's hi-tech ocean shield is heading out to sea. it's equipped with the u.s. navy's black box detectors. search crews have less than a week before the battery runs out. we're following the ocean shield. take it away, will. >> reporter: hey, carol. the ocean shield departed garden island which is western australia's largest naval base within the last hour and we have new video to show you. we were following it but i have to tell you it was going so quickly that one of the other boats with news cameras on it, as they were trying to keep up, we were trying to keep up, their engine died, they put out an s.o.s. call so we had to stop the chase, turn around and help that boat because they were in a busy shipping lane.

we want to show you the video we were able to follow the ocean shield for quite some time and i want to bring in the captain of the boat that we're on, the thunder, the captain to talk about how fast was the boat going and talk about those moments as we were following it, captain. >> we started off, he was running about 8 to 10 knots. by time he was doing 15 knots we were still in the channel. next thing we know we were getting a flashing s.o.s. from a boat that was there as well, lost someone over the side. always an emergency. and we had to give up following the ocean shield because could it be risk of life. >> yeah. as you always have to do. the way it works. captain, thank you so much. carol very dramatic to see this ship in action after hours of waiting today and we wanted to keep on speeding towards the search zone in the indian ocean some 1100 miles from here.

it will take three days to get there. on this ship is very hi-tech equipment that could be the key to solving the mystery of flight 370. they have an underwater microphone a giant microphone that can hear the ping. here's the problem. it only has a one mile radius and right now we have a search area the size paradise cove land. it's very important the aerial effort and sea effort continue to find debris to search in on that area. >> will riply reporting live for us on the indian ocean. four weeks after flight 370 vanished search crews have been unable to locate a single piece of debris. yesterday the australian prime minister tony abbott told us the search for that missing jet is ranching up. >> everyone wants to get to the bottom of this mystery. everyone is united in their common grief, in their common

anxiety to resolve this. i don't think we've got a whole lot of competing national pride at stake here. i think we got at stake here a whole lot of people who just want to solve the problem. >> malaysian officials say a new australian joint coordination center will take charge of synchronizeding search efforts in the coming days. joining me now to discuss are two gentlemen. welcome, gentlemen. >> good morning. >> david that australian ship equipped with those pinger locaters is heading to an area the size paradise cove land or new mexico. it just seems like a shot in the dark. is it? >> you have to understand what they are doing is positioning it so when they do find debris and able to locate or narrow in a little bit on the impact point they have it there and ready. it may take two days but at 15,

16 knots it will get there quicker. i'm encouraged that they are getting it out there and have the ship rigged to tow that pinger. >> it will take a couple of days for the ship to get to the area. the batteries in those black box start dying on saturday. give us a ray of hope. >> i'm afraid i can't. this is an enormous challenge. we've seen over the last three weeks exactly how difficult and how enormous the area is that we're searching. remember, this search area is identified based on sup suppositions. we believe this is the best place to charge. we have no real hard data to say this is the spot or this is the general area. even like we did with air france 447. so we are really taking a long shot here. >> so, david, at best we're hoping for like some dumb luck

out there in the ocean? >> i wouldn't call it that. it's more of a hypothesis or best educated guess. but when you're educated only on information that has a low degree of credibility and low degree of confidence it's difficult. but, i want to talk about 447 just for a second if it's all right. >> sure. >> remember on that one the pingers were not working at all and so, yeah, it was pretty futile having the pinger locater go across the top of it. in this case i hope the pingers are still working and work it down to a manageable area. if we can get that far within the next four or five days i'm confident we can pick up that pinger signal. >> malaysian authorities will ask the united states for more equipment starting tomorrow or next day. what exactly do they need? >> i think that you can't have too many vessels out searching for the pingers because their engine sounds wilkon fuse the

listening device but i think once a decision is made that the pinger battery has expired they will need an enormous amount of resources with underwater remote vehicles, perhaps submarines to search for this, for this missing plane. >> peter, david, thanks as always. >> thank you. in other news this morning artillery fire between north and south korea this morning. it came after north korea suddenly announced it would conduct live fire drills in the area. south korea responded by firing 300 shells in the north korean waters. the exchange of artillery fire forced south koreans living in the area to run for cover. this comes on the heels of north korea hintsing at more nuclear testing. we go to seoul for more. good morning. >> reporter: hi. >> bring us up to date on the latest that's happening there

right now. >> reporter: carol, nothing much has happened. this artillery exchange with both sides shooting in to the waters close to the flash point northern limit line in the yellow sea took place between 12:15 and 3:30. the guns on both sides fell silent. nothing has actually happened since things are actually reasonably calm here now. no one was hurt. no casualties. but of course the situation remains tense. >> then the other development is about this nuclear test and this is from the north korean foreign ministry. he said we won't rule out a nuclear test aimed at strengthening our nuclear deterrence. the u.s. better ponder over there and stop acting rashly. what do they mean by that? >> reporter: your guess is as good as mine. there's two possibilities. one could be natural they conduct another nuclear test it

will be using a different form of materials. previous nuclear tests have used plutonium as the fuel but they have a uranium enrichment program. they are planning a test with uranium. the second possibility is that they may have a smaller device, a device where they compressed that figures materials down into a size small enough to fit on top of a ballistic missile. if that's the case that's very worrisome because that will give them the full capability they need. that will give them an actual war head. >> thanks so much. crimian residents set their clocks to run on russian time. the back sea peninsula aligned its time zone with moscow jumping two hours ahead. it was marked with celebration following russia's annexation from ukraine earlier this month. vladimir putin's right-hand man, the russia prime minister is in crimea for talks on development.

malaysian authorities will hold what they call a high level briefing for grieving family members.

international experts including experts from china will update the families on the investigation into flight 370. perhaps too little too late for those families who still believe malaysia is hiding information. this candlelight vigil was held before today's regular briefing for family members in beijing. steve wang whose mother is one of the passengers organized it. >> we do not want to give up our hope. they are definitely still waiting for us somewhere. we hope that they will come home safe. even if that hope is so minute. even if there's only 1% chance. we will still give our 100% effort. trying to bring them home. >> families are turning up the pressure on malaysian officials

to respond to their demands. cnn paula hancock is live in kuala lumpur with that part of the story. good morning. >> reporter: hello, carol. the past few weeks have been completely unbearable for these families as you can imagine and some of the chinese families have actually traveled here right now to kuala lumpur to try and find out any information they can about their missing loved ones. ♪ praying for lost souls. chinese relatives of the missing airline passengers seek refuge in a buddhist temple. looking for comfort in the words of a monk. this woman says i really hope my husband and other passengers come home. the monk reprice i hope they will come back in peace. the 239 people on board the missing flight, 154 were chinese

citizens. the kind-hearted people this relatives says we can distinguish between good and evil. we'll never forgive those who hid truth. these families traveled from beijing to kuala lumpur sunday to be closer to the investigation. and they hope to information. they accuse malaysian officials of withholding information since the plane vanished more than three weeks ago despite government claims they are being transparent. they chant their demands. we want evidence, we want truth, we want our family. we're well into fourth week out finding any indication or anything about this plane and today, carol, the acting transportation minister was actually asked what will you do? have you discussed the fact that this plane may never actually be found. and in that press conference he basically said for the sake of the families i am not willing to

discuss that publicly, at least not at this moment. so clearly, it is something that has been considered but out of respect for the families they are not publicly discussing it yet. carol? >> paula hancock, reporting live from kuala lumpur. malaysia's transport officer insisted his government is not hiding anything although many wonder why authorities refuse to release transcripting between the plane and air traffic controllers. >> only those who are doing the investigations can give us the okay. if there comes a time when this can be shared with the public without concern by all means i will declare it. we're not hiding anything. we just following the procedure that is being set. >> with me now bob francis former vice chairman of the ntsb. good morning. >> good morning. >> in your mind, are malaysian authorities hiding anything? >> i don't think they are hiding anything. but i do wonder sometimes that

the most recent thing, a minister saying that he thinks that there's some reason for hope throughout this, the malaysian government has not, have not shown at all, they've been -- they've delayed and i can see why the families would be unhappy given what they had to put up with from the malaysian government up to now. >> we found the word hope used in the public briefing this morning unusual too or confusing, i should say because did he mean there's hope that these passengers might be alive or did he mean that there's hope we will find some sort of debris in the water? we couldn't tell. >> well, i think that, again, if it is possible to construe it as the former, it's the height of irresponsibility. and before you get up before the

world and start talking you better have some idea of what you're going to say and how it's going to be interpreted. >> let's talk about those full cockpit transcripts because everybody wants those released. the malaysian authorities say we can't release them yet. is that unusual in such an investigation? >> i think it would be unusual not to release transcripts. but then again the malaysian government continues to surprise me. >> but after 9/11 the full cockpit transcripts weren't made public until 2004 or something like that. >> i can't remember to tell you the truth. but that's a little far back for me. >> right. i under. i'm just wondering if these transcripts are part of a criminal investigation would they release such a thing right now to the public? >> that's probably a

justification for not releasing. if they consider this maybe a criminal act. >> last question for you, because i know you've taken part in many of these kinds of investigations, do you think they will find the black boxes before the batteries die? >> i think that the chances are enormously remote and i think even when the signals cease from the recorders, i think the finding of those recorders ultimately is very, very slim chance. >> bob francis, thanks for your insight as always. >> you're welcome. we'll have more on flight 370 in just a minute but first no plomtic progress has been made as tens of thousands of russian troops gather on ukraine's border. carl is there now.

. the russian prime minister is in crimea today. he's the highest level russian official to visit the region since it voted to join russia earlier this month. ukraine's military is preparing as up to 50,000 russia troops gather on its border. take it away, carl. >> reporter: carol, in the last few minutes we've been hearing

from the ukrainian government that's there's a change across on the russian side of the border. russian troops are repo signaturesing rather than pulling back from the border after those talks last night the russians are pulling more troops to an eastern sector to the northeastern sector there. how is that playing out on the ground here? ukrainian army is reacting. in the last hours they have been bringing up more armor to defend strategic positions like this main battle tank that's now being dug in and camouflaging it. many others dotted along with anti-aircraft weapons. not only the military that's in this fight in case the russians invade. the civilian population is also reacting. let's look what's happening in one village up on the border. ♪ >> reporter: faith they can avoid a war with the russians but just in case a little prayer.

this church sits on ukraine's border. its priest can't believe his old come raids will invade but if they do he's telling his flock to stand and fight. >> translator: i will preach our people to defend our homeland from any invader. this is the land of our grand fathers. i'll pray and if they need me i'm ready to join them to protect our freedom. >> reporter: he has brought his 3-year-old grandson for communion. his son is an army reservist. if conflict comes he'll be on the front line. >> translator: every mother worries when her son is mobilized. we under our young men have to protect the homeland. it's painful that our sons must go to war in the 21st century so we're praying for peace.

>> reporter: the faith doesn't line only in divine hands. in a nearby potato field ukraine troops mine a camera. they've spotted tanks, attack helicopters and even missile batteries. at a border checkpoint ukrainian guards shrug off the threat of war, but a fall back plan seems to be in place. the russian border is just a few hundred yards away. we've come across this, a series of what appear to be recently dug defensive positions including this trench but right now there's no sign of any ukrainian troops. the open farmland is classic tank terrain. the ukrainian villages say their best chance would be deep in the swamps where the grand fathers known as partisans waged a

guerilla fight during world war ii. our trip here is cut short. we were stopped by the border guard. they told us that's a closed military area. we have no authorization to be there so they are escorting us out. if things do turn bad, the priest and other villagers believe they have to tactical advantages over the russians. >> translator: we know the forest and swamps like the back of our hands. it will be very hard to fight us. truth will always win. god is on our side. >> reporter: even so the mood here is somber. mothers afraid they may lose their sons, ukrainians afraid they may have to battle old neighbors. this morning, carol, we started off taking a look in one of the forests over there.

the ukrainian troops have set up an emergency medevac field hospital, a lot of tent, there a lot of logistic, a lot of supplies going on. while that was happening then we come to this. we drive along one of the main highway, and dug in alongside. it's a t-64 tank. a main battle tank. this is 40 tons in weight and you look at the barrel on that and that way is the russian border, about five miles down to the russian border from here where we understand that russian troops are repo signaturesing, they also have their tanks and attack helicopters and essentially the commander of this unit here, you're a bit far away from the russian border, fire miles away. he said don't worry about that because the rounds from this thing will fly right up to the border, incredible really to think that if the russians do roll into this part of northeast ukraine that we could be seeing a tank battle in the middle of

this potato growing farmland. there are forest, there are swamp lands as well. it's classic tank country, carol. >> carl, reporting live from ukraine this morning. in other news crews searching for victims of that deadly mudslide might get much help from drier weather. days of heavy rain slowed the search. over the weekend the death toll rose to 31. 30 people remain unaccounted for. >> reporter: good morning, carol. you can see the river behind me is running very high. further up the way it's actually over the roadway off highway 530 where they have been having problems in the landslide zone. there the work is extremely slow going. more victim bodies need to be recovered. there's all kind of wreckage needs to be cleared. an infrastructure that needs to be rebuilt. really the recovery process has hardly begun.

search will go on for months and months to come no matter what happens. i think it was a very sobering view of certainly the challenge in front of them, and how long they are going to take to get it done. take a listen. >> the best brains in the world are applying them stoefls this task. all the technological mastery we have are being brought to bear here. so if this mystery is solvable, we will solve it. >> reporter: now still that nagging doubt, though, it's an if. the point here is that he just said it. everyone, it's all hands on deck. the best the planet has to offer in terms of technology and intelligence and still nothing. having said that they started the international coordination today. this will be the headquarters here in perth. and they will be at it for quite some time to come. >> i know malaysian authorities will head to the united states

to hawaii tomorrow, the next day to ask the united states for more equipment. what more does australia need? >> reporter: australia says it has a lot of resources and they do and they have a lot of expertise in this country. i think, though, at this point, as it's a global effort there are many more things that can be done because the search zone is so large. when the prime minister says that it's ramping up the australian prime minister the crews explained to me what will happen. before they were looking at satellites for debris on the top of the ocean. then they got more planes in sight to look at debris. now what's going to happen the planes will fly overhead, they have ten ships perhaps 11 or 12 in the next few days flooding the zone and then helicopters. this time whatever they spot on the water should in a few hours be able to figure out if it's something related to the missing flight and i'm telling you, crews say to me look we will

happening now, in the "newsroom," breaking this morning, malaysian authorities asking the united states for more military assets to find flight 370. families demand answers. >> we will keep investigating

and never give up. >> the ocean shield heads out to sea in hopes of finding debris. as cnn sits down with australia's prime minister. >> this is a very, very difficult task. nevertheless, we are giving it the very best shot we can. if anyone can find this aircraft, it's us. >> reporter: how long can this be sustained realistically? >> the effort is ramping up, not winding down. >> it is now a race against the clock as the battery life fades on those last boxes. >> both of those devices have been emitting a ping for several weeks. we believe they only have about a week of battery life left. live in the "cnn newsroom." good morning. i'm carol costello. thank you so much for joining me this morning. the search intensifies for malaysia airlines flight 370.

malaysian authorities will travel to the united states to ask for more military equipment. the batteries on the plane's black boxes will start to die on saturday. in the meantime, the high-tech australian ship, ocean shield, is on the way to the search area equipped with a u.s. navy ping dete detector. paula is live with more. >> reporter: good morning, carol. it is a good thing that that "ocean shield" is on the way to the search zone. the problem is, it still can't do its best work, what it is meant to do, until they find a way to narrow that huge swath of ocean now being searched. the "ocean shield" is ready and hours from sailing off to a search zone that so far has yielded no trace of flight 370. the australian ship will be the

linchpin of the investigation if and when it has been found. >> the first step is to find some debris so we can pinpoint an impact point to give us an initial search area. >> reporter: being fitted on board a u.s. navy towed pinger locator. and equipment that will comb the ocean floor looking for wreckage. >> reporter: it won't do any good unless the field can be narrowed. u.s. navy commander, mark matthews, is leading the team that will deploy the locator that needs to come within a mile. >> i can search approximately 50 square miles a day. if we are searching for a beacon and we are living on borrowed

time, i need something that's less than 1,000 square miles. >> reporter: right now, we are dealing with 100,000 square miles. >> yes. >> reporter: very low probability of detection if that is our search area. >> reporter: that's a sobering thought for the families of those missing. as we board "ocean shield" those working to deploy her are mindful every minute counts. the pinger signal will last little more than a week and any wreckage has been dragged by wind and currents for weeks now. you know, carol, we can tell you that the "ocean shield" is now deployed. it will take two or three days to get to the search zone. everyone aboard that ship including three key australian investigators are hoping that at least one piece or a few pieces of wreckage are spotted before they get there. carol? >> paula, thanks so much.

also, we have will ripley, another cnn correspondent. he is actually on a ship. he is following the "ocean shield" out to that search area when we get him live. of course, we'll connect you to him, because he has some interesting things to say. even though the "ocean shield" is on the way to the search area, there are no guarantees it will find anything. welcome, mary. >> thank you, carol. >> as paula said, the black box batteries start to die on saturday. is it worth sending this ship? >> i didn't hear that. say that again. >> is it worth it to send this ship to that search area, because we really don't know if the black boxes are there. >> oh, yes, it is worth it, because they can't just sit and wait. sometimes in investigations, you need a little luck on your side.

frankly, sending them out without detailed, pinpoint areas to search, they are going to leave a little luck. you can't leave that equipment sitting on the shore. if there is any chance at all they can find it, they have to do it. i agree with the previous commentator, you really need to narrow the search area, because it's just too big of an area for them to literally, as they call it, mow the ocean. they can start and starting is better than not starting. >> so once the ship gets to this area, which is the size of new mexico or poland, what's the first order of business? >> well, they have a grid. it is like they have divided up their search area kind of like a patchwork quilt. they take each one of the squares and they go back and forth with the finger finder and literally toe it hand the boat and it is kind of like sewing up the quilt. they do square by square, area by area. they are not going to cover all

the squares in the quilt of ocean. >> so the planes will be in the sky looking for the debris. is it of any use for that ship looking for the black boxes. >> yes. the debris can still be very, very important. if they find debris, they can calculate perhaps with the currents. here they say the currents aren't so fur roecious. what they will do with the debris is calculate the tides and the currents and tell that ship with the towed pinger locator where to locate and start looking there. the wreckage is vitally important and would really help. without wreckage, they just have to keep looking anyway.

hopefully, we'll find at least something to go on. >> hopefully so. what if they don't detect any ping? then what? >> it is entirely possible that they won't. there have been issues with how the batteries are stored and that would affect battery life. there is an issue if they have fallen very deep into the ocean. if it is on one side of an underwater mountainous, it might not pick it up on the other side. there have been some accidents where the pinger didn't start at all anyway. it is not a given they are going to have the sounds. if they are there, 3/4 of the time in a water accident, the pingers go off. certainly, they are out there looking for it to the extent that they end up in the right square and can find it. the wreckage would put them. they will be able to get on top of it if they find wreckage. >> mary schiavo, thanks for your

insight. i want to bring you out to the indian ocean. we have been talking about the high-tech ship, the "ocean shield" on the way back out. will ripley is on a vessel behind the "ocean shield". what is it like out there? >> reporter: we are going so quickly, the "ocean shield" is out of our sight. it is very determined to get to this search area in the indian ocean. there is a good reason why. there is just over a week left in battery life on the data recorders on flight 370. they have this great technology. this underwater microphone that can listen for the inningpings very short amount of time to search the search zone. there is a lot of concern this technology won't be effective. we don't know where to look in

an area the size of poland. this trip, this really has so many meanings. a lot of people are looking at the ocean shield as our last hope to solving one of the greatest mysteries in modern aviation. we are no closer today to zeroing in on where the wreckage might be. i was wondering what it was like out there? we hear how rough the seas are. tell us about that. >> reporter: here in covert sound where we are, the weather conditions are pretty good. water that's 100 feet deep, light waves. you get out on the indian ocean, specially when you get out to where this is, you have waves that are several stories high. the depth of the ocean goes down up to 16,000 feet. it is about 14,000 feet in the search area. that's incredibly deep. this is a mountainous, mountainous ocean floor, some of

the deepest oceans in the whole world. not to mention the weather that can turn from sunny and nice to horrific the next moment. i don't know if i have time to introduce you to the captain. if i don't, i can wrap it up. he has been out there and can tell you about it. captain, tell us what you were telling us about the ocean conditions and how quickly they can change. it was fascinating what you were saying. >> one minute you are out there in dead calm weather, people think it is lovely. the next thing you can have the waves over the top of your boat and everyone is sick. it is really hard to control. so you cannot tell the weather, even at a forecast perfect weather like today. they forecast 25 knots and here it is about 8-10 knots. >> reporter: it can either work for or against you. this is captain ray rubie, who is manning this charter vessel that we have been working on. there cob a ship pretty close to

you that you can't see. that's how choppy the waves can get out there. still to come. for the first time, we are hearing from the family of one of the flight attendants. the father says he is struggling to explain it all to his children. that story next.

we'll get back to the investigation of flight 370. first, artillery fire from south korea. it came after north korea announced it would conduct live fire drills. south korea responded by firing 300 artillery shells into north korean waters. it had south koreans running for cover. it comes on the heels of north korea hinting at more nuclear testing. barbara starr is here to tell us more. good morning. good morning, carol. i think the pictures are pretty coincidental but timely. about 13 u.s. south korean and allied troops in south korea conducting exercises as this latest violence broke out. a lot of worry that north korea

is announcing another provocation cycle. artillery shells fell in the water off the coast. an area that has seen a lot of disputes in the past. you see the american v-22s and amphibious vehicles right there. even as these western exercises were taking place. the question really is, how far is north korea going to go with all of this? will there be more provocations and what will happen next? this comes one day after north korea suggested it might conduct another nuclear test. carol? >> i wanted to ask you more about that. north korea did lob that verbal bomb at the united states and said, we would not rule out a new form of a nuclear test aimed as strengthening our nuclear deterrents. the u.s. better ponder over this and stop acting rashly. what do they mean? >> that's always a question with

north cre nkorea? what do they mean? the big worry about their nuclear program is that they make a significant leap forward to develop and be able to deploy a miniaturized nuclear device. why is that so important? you have to miniatureize a nuclear device to put it on the front end of a ballistic missile. that's what delivers a nuclear weapon to its target. it is that miniature zation that concerns the u.s. they are also working on a number of other technologies in their nuclear program. right now, no real indication about what they are talking about and still the question, is it all a lot of rhetoric or is this actually the beginning potentially of a new provocation cycle from north korea? carol? >> barbara starr reporting live from the pentagon this morning. there are new fears, landslide

search crews are handinging contaminated debris as they look for victims. hazardous household items in the wreckage could spike cases of dissen tary and tetanus. 30 people are still missing nine days after a mile of mud toppled from the washington mountainousside. the death toll went up overnight to 21. they are hoping the weather holds. you you have until midnight to sign up to obama care. anyone not covered by the affordable care act or private insurance could face a tax penalty. anyone that starts an application by today but is unable to finish it will get a few extra days before they are penalized. federal safety administrators may be to blame

the search is over for today and the ongoing quest to find the missing airliner. australia is leading the search effort and vowing to ramp up efforts as the mystery enters its fourth week. atika shubert spoke exclusively with the australian prime minister. >> reporter: it has been four weeks now. still, no sign of the plane. how confident are you of the information you are getting, that you are searching in the right place. >> it's the best information we have. it's the best analysis that we can get. it is the most professional search that can be mustered. >> reporter: you are confident in the information you are getting and that you are searching in the right place. >> we are searching a vast area of the indian ocean. this is a very, very difficult task. it is far more difficult than the search for the air france aircraft in the atlantic ocean a few years ago, because we had

very precise information as to where that aircraft had come down. we have just got very general information about where this aircraft has come down. nevertheless, we are giving it the very best shot we can. if anyone can find this aircraft, it's us. >> it is a tremendous effort. there are ten planes in the sky today, many ships. it is also exhausting every day. how long can this be sustained realistically? >> the effort is ramping up, not winding down. we'll have more aircraft in the sky tomorrow. we have more ships in the area. so we are ramping this effort up. we owe it to the families of the 239 people on board. we owe it to the anxious governments that want to know what happened to their citizens. we owe it to everyone who travels by air and wants the skies to be safe. we owe it to the whole world, which has been transfixed by

this mystery. we owe it to everyone to find out as much as we can. >> reporter: i want to ask about the coordination of the search and the investigation. australia is the coordinator. there has been conflicting information coming from malaysia. china has been very aggressive suggesting that it might get involved in the investigation. how frustrating is that for you to have so many countries involved what are the challenges? >> obviously, australia is leading the search. the legal responsibility for the investigation rests with malays malaysia as the flag of the airli airline that went down. i have offered prime minister

najib razak, the full cooperation of australia. the chief, very well respected in the region of water world, as the chief of the water world, angus houston can liaze with the senior officials. >> reporter: how would you categorize that cooperation or the challenges? >> challenges are considerable. let's not underestimate the good will. everybody wants to get to the bottom. everybody is united in their common brief, in their common anxiety. i don't think we have a whole lot of competing national pride at stake here. i think we have at stake here a whole lot of people who just want to solve the problem.

now. good morning, tom. >> gosh, malaysian authority are in a difficult place. they can't exactly say there is, like we believe there is a slim chance that the families survived this thing. . can they? >> they have been in a difficult place from the very beginning. the calculation done by technicians from all over the world. not just americans. even if the malaysian government had performed perfectly in the way they have presented their handling of the crisis, when they've had to change that, it gives them the appearance of being incompetent or not honest with their people and with the victim, families of this event. even when it is no fault of their own. they still look bad. >> right, right.

>> malaysia's acting administrator said he would not release the transcripts of the cockpit voice recorders. if there is nothing suspicious, why not release them? it seems like he is hiding something. >> that's what it seems like. in this country, we do things difr differently. many of these countries are not used to be pressed so intense civil by worldwide media. many countries in this situation would have released less information and other countries, maybe more. they have not had experience in having dealt with this many other times, thankfully. they are learning as they go in

how they put out information to the public and the families. >> the full cockpit transcripts weren't released until 2004. that is our president. >> in a major event, once a got loses credibility for whatever reason, it is pretty much gone for the rest of that event. they are going to be hard-pressed to ever get it back the way they are going right now. this is unfortunate. a large part of the confusion is not their fault. they may have changed their opinions about where that plane may have gone after it disappeared off radar. >> one way they are trying to patch things up for lack of a better term to hold this

and to a number of other tanks and personnel carriers to defend a small bridge or blow it up, in case the russians come. there is a sense of disbelief. they are allies. they have been allies. they have done a lot of their training together. a lot of their equipment is the same. this is a russian tank. this is just a sense here. how can we have come to this point? certainly, the ukrainian military taking things seriously. did anything come about it at all? >> you get the sense five miles from the russian border that paris, where their discussions

between john and sergei lavrov went on is a long, long away. here, down in the damper, they are making preparations for what they believe could be a tank battle with the russians. of course, it is not just about the military because the civilian population are also getting involved as well. they say they too will join the fight if the russians come in. they say they will divide up into small gorilla style units and use swamps and forests to use that as the launch pad to fighting the russians. they have been pickling fruits and vegetables and all kinds of that. there is a wartime spirit. people think they are coming pretty close to the brink here,

joining us now in the boeing 777. >> reporter: good morning, carol. we are going to talk about one possibility of how the aircraft may have gone in. depending on the way this plane hit the water, right now that is just a theory, would determine the kind of debris and wreckage that authorities could find. for this demonstration, we are going to ask mitchell to simulate the engines running out of fuel. the left engine, is that the one that shuts down first? >> normally. >> so we shut that engine off, cut the fuel off. even with only one engine, this aircraft continues to fly stable. it is not like it veers in one direction or the other other tips over. why is it like unaffected? >> we have a compensator, which is a computer that compensates for any a symmetric thrust. >> the other engine takes over without any problem and without any affect on the flight.

>> absolutely. >> let's shut down the one remaining engine to demonstrate what would happen in that circumstance. show us how on the gauges here we know that the engine is now shut down. both of them are spooling down. >> both of them are spooling down. you can see the external temperature. this is more or less the rpm. the actions left and right decreasing. it says engines shut down. >> you notice in the cabin it has gotten quiet. essentially, this jumbo jet is now a glider. are we on autopilot or not? >> we are on autopilot. if you take the autopilot off, the airplane will start to glide. >> this is the thing that's so amazing about the design of this particular aircraft. even with no one at the controls, even with no power being generated by the engines, we are still level in flight. we are going to lose altitude. we are, slowly starting to go down by maybe, what's the rate

of dissent? >> it is a very gradual dissent. the horizon is very normal. the design of the aircraft is meant to fly, even without fuel and without anyone at the controls. >> all right, martin savidge, mitchell casado, many thanks to you. >> they are just days to help locate the black boxes with the pinging noise. the u.s. navy has a high-deck device that may help narrow the search. brian todd is in washington to explain how that works. >> this device is called the towed pinger locator. it is made by phoenix international. this video you just showed was of our visit to phoenix

international to get a look at how it works. this device is now on board the australian ship, "ocean shield" as it heads out. how it works is if a piece of wreckage is found, only if a piece of wreckage is found, they tow this device back and forth for miles at a time, many miles at a time, sometimes hours. it will listen intently for the sound of the pinger on the black box. it can pick up that sound. here is my conversation with paul nelson about the distance involved here. how far away can it be, him picking up. >> the outside edge is two miles, a mile and a half to two miles away, it can detect the sound. if we hear it and barely hear it, we would turn the boat around and come closer. >> so it can even detect the
