jim clancy is live in kuala lumpur for us this morning. and jim, we understand you just obtained a transcript of the final communication. what does it show you? >> reporter: this is the full transcript between the tower and flight mh-370. in it, you hear all of the things that are going on between the pilots on board the aircraft, air traffic control, ground control, the kuala lumpur tower, as this flight proceeds. it carries through, you know, from the time that they say that they want to take off, cleared for takeoff at 12:40.38, 370 32r, 32 right, cleared for takeoff, goodnight. then malaysian airlines said "cleared for takeoff, malaysia 370, thank you, bye." the final transmission comes at 1:19.29, and the transcript from -- this is from malaysia airlines flight 370's cockpit, says "goodnight malaysian 370." this came to us via senior government source, highly credible. i'm not an expert in aviation. we're going to have some pilots take a look at this. but i can tell you, as i went down through this three, four times and read everything

i'm not sure who would be doing that. >> do we still have jim clancy in kuala lumpur? ? >> reporter: no reaction from malaysian authorities, but the australian authorities from the joint confirmation center are not confirming it yet. this is basically a two-line report from the xinhua news agency saying they located it and transmitting at this frequency once per second, which would be correct. at the same time, it doesn't say how long they heard it for or where they heard it or is it still transmitting. there are so many unanswered questions as yet. i want to wait and see if we get confirmation here. one positive note that i think we heard today coming out of malaysians was from the ceo of malaysian airlines. he said they actually rotated or replaced the batteries in those flight data recorders, cockpit voice recorder ahead of schedule. faster than they were required to. he said this particular set of units was apparently going to be serviced again come june of this year. so, the batteries should have been in pretty good shape. at least that's what the indications are f

jim clancy has that part of the story from kuala lumpur. and jim, now they're sending in two new ships as well. what are they thinking in terms of this helping in the investigation? >> reporter: well, you know, they want to find out what happened. they are committed. they've told china, they have told the countries, the nations of all of the passengers on board the plane that they are going to do everything humanly possible to sort out the mystery of flight 370. they know the world's aviation industry is concerned. they know the nations are concerned about the safety of their citizens. they want to prove that they can handle the job, so they're reacting in that way. as you put it, you know, the inspector general, the police here coming out and saying, yes, it's a criminal investigation, yes, we've interviewed more than 170 people, but no, we don't have a firm idea of what happened inside that cockpit. meantime, we've got the families meeting with government officials again, a bit of two points of view on that. it was a three-hour meeting tod

our jim clancy is tracking all of this for us in kuala lumpur. he has been there all through for all 28 days of this exhaustive search. you know, jim, it was with you live last week that we got the full transcript of the transmission, but the families want to hear it. >> reporter: certainly. they want to be a little bit closer to the investigation. they want to feel hands on. and so, they're making requests, hoping that, somehow, they will understand perhaps what the investigators have not, by listening to those voices, even in a different language. they want to grasp at anything substantive that they can. but they were told by the department of civil aviation that that's not going to be possible, that those are part of the ongoing investigation. even, we are told, the pilots' families have not been allowed to listen to those. now, they do have a recording, youtube video recordings that were posted by captain zaharie shah online. he posted some self-help things, a home repair and talking about his simulator online. as a result of that, they do hav

jim clancy has seen the transcript. tell us more. >> reporter: carol, you look at this and it really stands out. what this transcript shows us is that the conversation between the control tower and that cockpit of flight 370 was entirely routine. this transcript while it doesn't break new grounds may actually add to the mystery. it does clear up inconsistencies. watch. >> breaking this morning a copy of the transcript from flight 370 confirms no one in the cockpit ever said, all right. good night. instead the final voice transmission at 1:19 a.m. actually was, good night malaysian 370. for weeks malaysian authorities said, all right, good night were the final words said before they lost communication. >> the rest reads like a normal cockpit transcript. someone saying good day and good morning while the plane was taxiing. during the takeoff at 12:42 a.m., someone said "departure malaysian 370." about 15 minutes into the flight, another voice transmission. "malaysian 370 maintaining flight level 350." then the final words

let's get to jim clancy, live in kuala lumpur with the latest. jim, you have been following this throughout, for weeks and weeks now. and you know, we're getting sort of a difference sense. it's feeling to us, at least, here, like this investigation has stalled in a way that it hasn't in the past few weeks. would you say that's a fair assessment? >> reporter: it is a fair assessment, especially looking from the outside in. huge thunderstorm going on right now in kuala lumpur, just to explain that. from the outside in, it looks stalled. perhaps they have evidence they're not telling us about, but already, you know, you have some family members, some loved ones, like sarah bajc, who's come here. philip wood was her longtime companion, and she has come here. he was the american on board. she has come here to take up residence, take up a new job. this was all preplanned, and she wants to get together with the families, she told cnn today, wants to get together with them and discuss with them, keeping the investigation alive, number one, and number two

kuala lumpur, malaysia, and our jim clancy. jim, i remember when this mystery was just a few hours old. you were there at kuala lumpur airport. who would have predicted we'd still have no answers 31 days into this? tell us how that place and the malaysian people have handled this major international event over the past month? >> reporter: you know, i don't think anybody would have. certainly i wouldn't have. we arrived here on the 8th of march. it's now the 7th of april. i really thought this would be resumed if not in a matter of hours, in a matter of days. our evidence told us that the plane was last seen in the middle of the south china sea. it was only three, four days later that cnn, through sources here, determined that, in fact, that plane had made an abrupt reversal in course, flown through the malakas straits and was on its way into the indian ocean. some 90 minutes after takeoff. it opened up a whole new world of questions. and we've seen it. you've seen it, don. the speculations that read like movie scripts about what

jim clancy has been in kuala lumpur following this story from almost the beginning. here's his perspective. >> stot were by began at the arrival gate in beijing where it was listed as delayed some six hours after it disappeared in the south china sea. >> we have breaking news right now. malaysia airlines confirms it has lost contact with a plane carrying 227 passengers and 12 crew members. flight mh-370 was headed to beijing from kuala lumpur. it was a boeing 777-200. it was expected to land at 6:30 a.m. local time. now, it's almost 9:00 in the morning in beijing right now. that means that plane is 2 1/2 hours late. >> the confusion, concern and fear at that hour, completely predictable. everyone dreaded the worst, a terrible accident. >> we have confirmed this flight, mh-370 lost contact with air traffic control at 3:40 a.m. this morning. >> most people at initial stage thought that it was a straightforward crash and that you have come down somewhere south of vietnam and the wreckage would be found very, very quickly. >> reporter: malaysia waited to reveal details o

jim clancy live for us.osemary. >> errol, these new audio signals were detected, and they were racing against the clock to try to find the black boxes before the batteries inside the becons go silent. aviation analyst michael kay and and liz aben, joined us a short time ago. take a listen. sglipt to start with you, michael and get an idea of what you make with this and how cautious you were being and on you encouraged you are being as well? >> all of the above, i think the reality of this is that what we have seen so far since day one, has rewritten the history book in terms of the way of crash investigations will be done in the future. we have effectively bypassed the haystack and zoning in to needle. which is unprecedented in accident investigations. however, we do need to maintain this that element of cautious optimism, yesterday, during our chief master houston's press conference, i was optimistic and having heard what the air marshal said today, i'm more optimistic than cautious and there's reasons for

jim clancy circumstances thank you, jim, has been, again, in kuala lumpur since the very beginning, coveringwatching the families from the beginning. just a roller coaster of emotions for them. one day they think they have some answers. the next they don't have any answers. one day they're being told that everything is lost and the plane is in the ocean. but still, no evidence, no sign of their loved ones. and they really want to come -- they really want to get some answers here. and we can understand why. >> hello, everyone. i'm don lemon. i want to welcome our viewers in the united states and around the world. in just minutes, the head of the joint task force hefding up the search for malaysia airlines 370 is about to speak. all me we know is it is a, quote, update and read into that what you will. an update. but we will bring you that live, just as soon as he steps out, as soon as angus houston walks out, we will bring that to you live. and here is what we do know, though. for the first time, we have what could be sound from the plane's black box. search crews are scouring the indian ocea

jim clancy has been in kuala lumpur almost from the beginning. >> reporter: the story with 370 begane arrival gate in beijing, where it was listed as delayed, some six hours after it disappeared over the south china sea. >> breaking news, malaysia airlines confirms it has lost contact with flight mh-370, it was a boeing 777-200, expected to land at 6:30 a.m. local time. it's almost 9:00 in the morning in beijing. that plane is two and a half hours late. >> reporter: the fear completely predictable. everyone dreaded the worst, a terrible accident. >> i confirm that this flight lost contact with air traffic control at 2:40 a.m. this morning. >> most people at initial stage thought it was a straight forward crash and it had come down somewhere south of vietnam and that the wreckage would be found very, very quickly. >> reporter: malaysia waited to reveal details of its own military radar, the plane had deliberately reversed course, heading toward the indian ocean. >> how much of a turn back did it make? 20 kilometers? 10? >> we are still looking at that. >> reporter: suddenly anything b

jim clancy in kuala lumpur. transcript of the -- all of the communication between the air traffic controller and the cockpit of flight 370. jim said it looks routine, by his owned a mission, though, he says he's no expert but he has covered his fair share of plane crashes in his day so he probably knows a little better than the average person on the street but we are going to get that checked, we'll have it looked at, we'll have an expert look at it to see if there is anything out of the ordinary and as soon as we have that we'll bring it to you. right now a three-page transcript all looking very routine. >> and you can be sure over the next hours people are going to go through this and through this word by word and see what can be read into it. we don't know. at this point it's all speculative, not a lot to go on. but the debate over exactly where flight 370 went in the hours after communication was lost is, of course, heating up. >> that's as new claims emerge about the plane's flight path and who may have cha

jim clancy joins us live from kuala lumpur with more on that. jim, the australian prime minister described this as one of the great mysteries of our time and at this point that does not seem like an overstatement. >> no, not at all. and obviously people are going to be finding fault with the investigation, but the fact is that there aren't any facts. very difficult for them to know what went on inside the cockpit short of obtaining the flight data recorders. and there's a problem with that, as we all well know. at the same time, the industry is looking at this not for the first time, looking at this and saying something probably has to be done. they look at the circumstances that are involved with flight 370 and they say in the past we've considered all of this but maybe this time it's time to take it seriously. take a look. >> we can't find it. we're not even sure we're looking in the right place. because flight 370's transponder was purposely shut down by someone in the cockpit or failed, search teams have been left to scour millions of square

cnn's jim clancy is covering that part of the investigation.he is live in kuala lumpur as he has been for the last month. i have so many questions about everything that you've been covering up until this point. but this latest news about skirting the indonesian air space, what are the investigators saying about that? >> reporter: the investigators aren't giving their interpretation of it. this source told cnn, this was the course that was tracked on radar. that radar would be very reliable. we're not sure which country provided it. we know that the indonesian -- the malaysians were tracking it. but this gives us a little bit more coverage as it comes around thailand or indonesia might have furnished some of this data. what it indicates to us is that the pilot was trying to avoid, you know, impinging on anybody's air space. indonesia's air space. something that might prompt a response. that the plane has already flown directly over malaysia. but it was a malaysian airliner might not have prompted a response for that reason or as it would seem, n

. >> this was jim clancy reporting. the task force trying to improve tracking of international aircraft. >>> it's hard to imagine the suffering the families are going through. husbands, mothers, fathers, wives, children, gone in an instant. some accept it. others are holding out for a miracle. >> she has been flying with malaysian airlines for 18 years. a lovely wife and a caring mom for my two qukids. yeah. [ speaking foreign language ] >> she's the glue that holds things together, my sister. it's a roller coaster ride. it's difficult for the families. we're hoping there will be survivo survivors. if it ended in the indian ocean, we hope there are survivors. we hope that there is a light at the end of this tunnel. >> i definitely miss her. she's a very committed, professional pilot. if something had happened to this flight, i would think, in fact, i would believe that he would have made sure of the safety of the flight than himself. so, i'm praying not just for the pilot's family but the rest of the passengers and crew

jim clancy, thank you so much. quest, i understand you've been listening here and there's something you want to add? >> what jim said is interesting and important. what jim says is exactly what you would have expected both of a criminal and of an aviation investigation at this stage. those people who need to hear the audiotapes of the air traffic control have heard them. the friends or the family or the colleagues, anybody who could identify who was speaking those words, malaysia 370 from the cockpit. that is significant. it shows us that the authorities are letting those people hear the tapes who need to hear the tapes to help with the investigation. it's not a blanket ban, as some would suggest, if jim's source is correct. what they will not do and they never do is give a general release of cockpit audiotapes. the prejudicial effect, the fire storm of hearing the people's voices at the moment the plane is doing whatever it's doing is simply too great. it will be the cockpit voice recorder that will have it on it.

jim clancy, cnn. >> and we continue on. >>> hour two, i'm brooke baldwin. with me on this friday afternoon. here we are. four weeks ago today, flight 370 vanished. and now the search has totally changed. searchers have taken the mission underwater. that's what i mean by the change. scouring this 150-mile track of the ocean floor trying to locate the black boxes before the pingers on the devices go silent. assuming they are still emitting any pings at all by this point in time. batteries could be dead. crews today dropped a u.s. pinger locater in the water. here's what it looks like here. it's a listening device. hoping it will listen for and pick up the pings emitted by the two black boxes. also on stand by, this is an underwater robot, a blue fin that uses sonar to check the seabed for wreckage. it's important to get a reality check. one scientist who helped develop the flight data recorder technology, the black box technology said finding them at this point would be, quote, remarkable. the australians still hopeful on finding a debris field. >> i think th

>> all right, that is jim clancy live for us. >> errol, let's get more analysis now from a navy experts joins us from perth via skype, and he is editor and chief in airlines ratings.com. you have been following this from the start. you have been with cnn, giving your perspective and analysis on this. i do want to get your reaction to all of this information, this new information we received from angus houston. what do you think here? >> well, rosemary, if this double ping, these two conteact we have had in the last few hours is correct, it's been an on outstanding piece of detective work. it's a real international effort using the satellite. because, we must remember here, the line that the ocean shield and hms-echo the british survey ship have been tracking on a converging course, this was the first course they were given by the crash investigators to tow these pingers. and the ocean shield appears to have located what may be the black boxes. if that is the case, this is an outstanding piece of detective work. >> and it's interesting, jeffrey, some analysts have said, that it was prem

jim clancy, cnn, kuala lumpur. >> our thanks to jim.e has been doing some terrific reporting from southeast asia. cnn's aviation correspondent, richardest, along with aviator and royal air force lieutenant colonel michael kay. i keep coming back to this question every time we alter the search locations. based on new metrics. how is it that 28 days later our math, using the same data from 28 days ago, is different? >> because it was shaky to start with. and it's at the edge of our understanding of technology and science. this is not like one plus one equals two. this is an entire new way of thinking and looking at the same data. and each time they do it, they get a little bit further in understanding. you have to understand, ashleigh, that they have said it again and again. they really are using data that was never intended to be used in this way. and therefore -- and i'm not being uncharitable when i say this or pejorative. but they are making it up as they go along. they are literally having to go back and again and again. >> as it see

jim clancy, kuala lumpur. -- captions by vitac -- www.vitac.com >>> you are in the "cnn newsroom" and i'm brianna keilar in for don lemon. today, in the mystery of flight 370, search planes should be taking off to pursue the latest leads a. chinese search crusade that earlier today, their equipment caught some pings on a frequently usually used for flight data recorders. there is more information about that though, and we will get to that in a moment. p but at the same time that those pings were detected, a crew flew over white objects. and so the debris is 90 miles from where the pings were heard. this is adding new cautious new energy to the frustrating search that has lasted four weeks. military and civilian airplanes, 13 in all, have crisscrossed the search earea today, and 11 ship with high-tech scanners have worked the ocean surface. in perth, australia, our cnn international correspondent is there. matthew, you are at the head quarters of the search, and how much weight are the commanders putting on the new, but unconfirmed pings of the detectors of the chinese? >> well, they a

let's get the latest from jim clancy in kuala lumpur. jim?t it really shows more than anything else is that this was an entirely normal dialogue between the control tower and the pilots inside the cockpit of flight 370. it started at about 12:27 in the morning. a voice in the cockpit saying, ground mas 370, good morning charlie 1, requesting push and start. by 1:00 in the morning, the plane is aloft and the cockpit of flight 370 says, malaysian 370 maintaining level 3-5-0, meaning 35,000 feet. and then that final transmission this, at 1:19 in the morning, good night malaysian 3-7-0. there we have it laid out. there was confusion over what was said. officials even confirmed that it was, all right good night, by now we have the transcript in our hand. one of the small bits of hard evidence that there really is in this entire mystery. chris? >> information has been hard to come by. and then every time we get it, it seems to contradict what we learned before. >> let's continue the discussion. we're joined now by david, a cnn safety analyst and th

let's get to jim clancy who is live in kuala lumpur for us yet again this morning. jim?on may have produced, but the inspector general who's in charge of the probe did talk with reporters and tried to outline to them some of the things that they've been looking at noting that it's been a criminal investigation sings march the 16th. he said, as you noted there, all of the passengers have been cleared of any involvement in the four areas that he said mattered, sabotage, terrorism, psychological problems as well as personal or financial problems. there is a step forward perhaps. he said it has been a thorough investigation. they're going every way possible. they even investigated -- there was a shipment of thousands of mangastein fruit aboard that flight. he went to the people who picked it. they're checking everybody who packed it, put it a board the plane. even the people who were receiving it in beijing and how much they were going to pay for it. by way of illustrating how thorough, they were checking often the people who prepared the food. he didn't say that they were s
