experts and the search team think wreckage. could you perhaps -- is that a possible scenario that you're looking at? >> that would be speculative. good morning. christi paul and victor blackwell here. an intense search this morning as they frantically try to find malaysia airlines flight 370 before the black box stops pinging. you are watching a live press conference from malaysia right now. let's continue to listen. >> -- four days. individuals have tolds that you none of the family members have been able to listen to it that recording. it would seem that apparently a commercial pilot or the first officer would be able to

identify the voice on the recording. why have you not allowed the families of those individuals listen to the recordings? >> it was first a transcript of the conversation between the pilots and the tower. and i managed to convince the investigating authorities to release that. on the audio, i've been told that they are still investigating the audio evidence that exists. and it's still pending investigation. it cannot be released at the moment. is that it? >> okay. ladies and gentlemen that concludes this session for today. >> thank you very much. okay. he just mentioned something that has been quite a question for a lot of people. mainly the fact that there's been so much scrutiny with

malaysia authorities on how they handled the whole situation with flight 370. but lately, for the families, about why they will not released transcript of the audio recordings from the cockpit. they released the transcripts, but they wouldn't release the transcripts. and he is saying there now, because it's a pending investigation. but it was interesting, too, notice, victor, how he said, i managed to convince authorities to release the actual transcripts. >> yeah, i picked up on that. >> so it sounds like there might have been some dissension between these two. >> quite possibly. quite possibly that was the end of the question at the conference. remember, we got news during the news conference, that the chinese had found some image on satellite. he held up the page saying here it is. i've been accused of holding back information so let me show it to you now.

again, saying that he is trying to convince some of the organizations there to release the information. the other news we got out of this is the formation three of committees to tackle the flight. one to deal with the families. the second will oversee the investigation team. the third will handle the deployment of assets. maybe this is the evolution of the search. we're going back now four weeks to today since the beginning of this flight. it's unbelievable it's gone on this long. are we now transitioning into a different phase of this search and this is now the long-term search after. the pingers are expected -- the batteries on the flight data recorders quite possibly expected to die out within the next few hours. >> and also i believe we learned, and producer, help me with this quite possibly, that

the flight recorders were due or to be inspected in june. so we are right at that 30-day mark here. >> yeah, we're within hours here, guys, i think it's 1:30 today will be the 30-day mark from when if this plane indeed went into water, we have a flight data recorder here on the desk with us to give you an idea of what it looks like, the size and kind of the dimensions and the parts we're discussing. here it is. this is not the exact model that was inside malaysia airlines flight 370. but here on the front, this is the pinger that we've been talking about. and this, i'll spin it around here so our camera can get it. you see that dot in the center. that is the center so once it's submerged in the water, the pings will start, one every second for 30 days. and if this plane was indeed submerged into water and crashed as the prime minister back on

the 24th into the south indian ocean, then that would have been the day that the ping started. and we are now 30 days from that coming up at 1:30 today. >> let's get more from cnn's nic robertson. he's live in kuala lumpur, malaysia right now. nic, anything stand out to you regarding this news conference, and what else are you learning today? >> yeah, we have two questions from the news conference from cnn's staff and really not particularly forthcoming answers from hasan mudmean. asking him if there were altitude changes, really key and important information that a lot of people are asking for. the acting transport minister stirred it around that.

saying eventually week able to get cooperation from all the different countries for the radar data. but he wouldn't say how many turns the aircraft had made. or if any altitude changes. the question there about whether or not the families of the first officer and the captain who have so far not been able to hear that voice data, been able to hear the conversation for the cockpit between the air traffic controllers which would help identify who was giving the last signoff there "good night, malaysia 370." again saying investigation and that's why the families haven't been able to hear it yet. the families of the first officer and pilot. perhaps the information was coming from the ceo of malaysia airlines talk about the batteries in the pingers. the pingers attached to the black boxes. the concern that the batteries were due for change some time ago. he said, no, their scheduled maintenance was coming up in

june this year, so really trying to lay that to rest. again, some inside malaysian political issues coming up. and also talking about the malaysia overseeing the investigation, inviting china, australia, united states, united kingdom and other countries to be part of the investigation. the other thing that stood out to me, the three ministerial committees established here overseen by deputy ministers, two of the deputy ministers report directly to the man you heard speaking there, the acting defense minister. despite the fact they're handing off these admissions they're going to be direct subordinates of his, which gives you an idea just how much control he wants to continue having over the unfolding events there, victor? >> nic robertson there in kuala

lumpur. nic, thank you very much. let's talk about this with mary schiavo. >> and also simon joining us from southampton, england. simon i want to start with you, four weeks into this flight, were you able to hear what the acting transportation minister said this morning? and if so, what did you take from that news conference? >> i did. i mean, the first thing to say is that the 30-day battery life of these pingers, just about the talk of the deadline, it took a lot longer. we know that these things can go twice the battery lengths sometimes, but also, they can go a lot shorter. we're assuming that the black box and pinger were damaged in the crash. it's very likely that the plane would have broken up. it's highly unlikely that the plane would have landed whole.

bear in mind, we're searching an area greater than the great lakes of america. >> mary, what do make of the committees they've talked about branching out? because there's been so much criticism of how malaysia authorities have dealt with so far? is this say good shift to create these three committees? >> it is a good shift and it's a pretty standard shift when the united states, or great britain or france countries used to doing accident investigation, that's what we do. we form committees. and the committees are tasked to work on their areas and they report back to the investigation as a whole. when you have a public committee, or public hearing, each of these committees generally reports. so this is a very efficient way to deal with the investigation. and also a way to make sure all of these important areas get covered. i actually expect they'll form more committees as time goes on. >> simon, i want to talk about a different type of shift.

the continuous shift of the search areas day to day. do you attribute that more to either questionable analysis of the information and data? or is this shift appropriate, considering if the plane went down in this area, the currents and the natural movement of water was shift the debris field or elements, as we see here, closer to or farther from the coast of australia? >> i think the key thing for us all is that the only note was the last satellite location of the plane. from there on, there's a certain amount of, i suppose, educated guesswork, how far it had flown from that point. it's sort of a big shift north from the last known located ping from the inmarsat system to about 75 miles north of where they were beginning this week. with that, based on the aircraft range using fuel, which seems to be a long time to come out from

the malaysian got and the airline itself, that that did some shift. but the question is, any search efforts how far as it gone, and moving that how to estimate the wreckage. that's not easy, because it can be a number of directions and quite fast in the area. large items would eventually sink, and really, begin the stage now where they can begin looking for relatively small items. that's going to become more difficult. and they're searching an area greater than the great lakes. >> simon, i just want to ask you a question because i'm not sure i understand what you're saying, but i heard a past expert we had on the show say once that based on what he knows of wreckage, within three to four weeks, some debris could be washing up on

the shores of australia. how -- >> no. >> no. okay. >> 2348s it's taken back by ship or ferry, there's no way that the winds will blow on to the shore of western australia. if the plane went down in the original search area, 2 would be some years before anything washes up on any beach anywhere. it's likely to be west australia. but it's going to take a long time before anything washes up on the shore there. we're talking months, we're not talking weeks. >> thank you for the clarification. >> amalaysia government source called that sharp turn we've seen in the animation a criminal act. my question is without any credible leads determining exactly what happened on flight 370 or any debris field or really any narrative here, how credible is the determination that that was a criminal act? >> well, i don't think they can

say that for certain at all. i think they're making their hypothesis that that was the case. and they're basing it on the assumption that the plane cannot turn without the hand of a pilot actually turning that plane. as we've seen over the last several weeks with the simulator demonstrations and through various reporting through 777 pilots, this plane, of course, can make the turn. you can do it in various ways, autopilot. there's an emergency descent procedure. and they're announcing the only way that would have happened is with human intervention and that's entirely possible, with some kind of emergent situation on board. what's even more trouble they go have announced this but have not put forward anything that would explain that. for example, they have not released the audio of the

transmission. will not release the data. to release the inmarsat data. and they said all the countries have provided their radar data but they would not pursue them. whatever they are pursuing they're going to keep a close hold on that evidence. i guess the most disturbing thing, not in this press conference, they talked about prosecution. prosecution, you can't prosecute dead individuals and send them to jail. so it was a clue they are looking at others so apparently, that particular item is not on the agenda today. >> mary, simon, thank you so much. appreciate your perspective. of course, we'll have much more on the search for flight 370 in a moment. also just ahead, the ft. hood shooter, he did not leave a suicide note. now investigators trying to figure out why he went on that shooting spree and killed three soldiers.

this is what it sounds like. do you hear that? that's the electronic ping, it's not really audible, human ears can't pick it up. of course there's a catch to this. >> battery pingers may have only days or hours left. which apparently is a game-changer once that happens. if they can find something in the next 24 to 48 hours. joining us from london, alastair is here with us. >> good to have you here. a senior u.s. official tells cnn, actually, our pamela brown, that investigators have discovered that they programmed alternate routes and searched what to do in flight emergencies, and they called that curious. is it curious that a pilot, a captain, would do that, or is that just due diligence.

you would want your pilot to do that? >> i think it could be seen both ways. certainly if a pilot has access to a simulator, he will indeed practice diversions. when you have a diversion come up, it's usually unplanned, that's because weather's changed or runway is blocked, typhoon whatever. you have to think fairly quickly and that -- as a commander of an aircraft, you want to be on to those possible situations. what is interesting would be which diversions he planned. and that, of course -- they haven't told us. >> as a pilot, do you and maybe does your family expect this type of scrutiny in investigation, the scrutiny that he and his family and the co-pilot have encountered thus far? >> oh, absolutely. i mean, whenever there's an accident or serious incident,

authorities, federal aviation authorities, civil aviation, whatever, will indeed look into a past. they'll look into whether you've been resting properly, whether you've been drinking. your financial affairs, just about anything. and in the event of an accident, and especially when the accident is unknown and the aircraft's disappeared, then the scrutiny will be much, much higher and deep in nature. so, yes, whether or not his family expected it, that's entirely another meat. but pilots would expect that, yes. >> well, we're -- well, when i say "we," the search crews are still looking for the cockpit voice recorder. we know that the last two hours of the audio there have been some who have called for 24 hours of recordings. what do you think about that, extending it to 20 to 24 hours of the cockpit voice recordings? >> well, the longest flight is probably going to be 14 hours the absolute tops so it probably

doesn't need to be longer than that. i've always been in favor of a longer cockpit voice recording and i'm record for having said so for many years now. but the pilots union is probably against because it means that all their conversations, private conversations, could indeed be monitored by management. it used to be half an hour, they've now extended it to two hours which is an improvement. but as you quite rightly note here and this is what i'm reading into it, is that there will be no lording, the critical period where the aircraft turned back. and if it was an encompasiencoe. we have no idea. >> alastair rosenschein, thank you for being with us. we appreciate your perspective. >> thank you. coming up on "new day," understandably, we've talked about the search and the assets.

i'll bring you an example that we can talk about. passive sonar is the idea of pinger listener. it's device that is towed behind the ship and it's listening passively to the sound of the flight data recorders. and it has to be within a mile of two of hearing them. if it does, it can be a sense whereof the plane might be. very slow process. the ship's not moving fast at all. beyond that, there's the question of active sonar and that involves a robot. essentially if we drive below the water here, we can talk about this device that sort of looks like a torpedo. it's put into the water and can operate for 24 hours at a time. it goes through the water, about half a football field at the bottom emitting sound waves, bounces off of things and then it recollects. and by doing this, symbol is essentially a sonic picture of the ocean floor. and that picture can be studied

for any sign of abnormalities that might suggest there's a plane or part of a plane back there that they can look again. that's the technology side. the educated guess is figuring out where to deploy that. they've done that, they just have to hope that they're in the right place. victor, christi. >> tom foreman. thank you very much. appreciate it. >> of course, well ha'll have mn the search for flight 370. but something people are talking about. this baseball player who is being slammed for staying with his wife as she delivers their first child. we'll talk about this next. ♪ norfolk southern what's your function? ♪

i know you've been talking about this weekend, two new york radio shows getting slammed for taking mets daniel murphy to task after missing opening game to be with his wife after giving birth to their first child. >> assuming the baby is fine, 24 hours, you stay there, baby's good. you have a good support system for the mom and baby, you get your [ bleep ] back to your team and you play baseball. >> i would have said c-section before the season starts. i need to be at hoping day, i'm sorry. >> the last guy you heard from there, former nfl quarterback boomer esiason. he is sorry. he said he never met to tell any woman what to do with her body and bringing the personal life of murphys into the spotlight. >> and jennifer owens -- as soon

as i say this, you know where this is going -- jennifer, let me ask you first of all, what was most offensive to you in this conversation? what has people so riled up? >> i think that immediately it just negates the role that fathers have in their child's life in the formation of the new family. and anyone who has had a baby knows that it's more than 24 hours of parenting is happening in those first few days. >> and his apology. he has apologied. a lengthy apology. he said he never met to tell a woman to do with their body. and it's my fault for mentioning c-section and put their life under a spotlight. it put that into reference -- >> the c-section, especially. >> why do you think that has people riled up. >> i've had two, they're major

abdominal surgery. nobody wants to have that. it's really hard to recover from that. to have your husband there and your baby's father there to be part of that moment is extremely worthwhile. >> i've had three. let me tell you, i concur. i'm with you. not only that, i think people equated ignorance to that statement because for the safety of the baby, you can't just schedule a c-section at an appropriate time, they say the longer they're cooking in there the better it is for them. we know, women usually do take the brunt of maternity backlash. you're judged at work because you can't be there, whatever. in this case, the dad, daniel is getting this thrown at him. how do you think that dynamic is maybe a positive to this conversation? >> oh, definitely. we do the "working mother" 100 best companies. across those companies they

offer three weeks of paternal leave. the men don't take it all-here he has the benefit of three days and he took two. so men need to be encouraged to use it, throb. and i just like this conversation that men are calling into the show and saying they are completely wrong on this. >> yeah. that's where i want to take it. boomer's getting the pushback here. the other talent there on the show. at least we're having this conversation, right? >> uh-huh. exactly. exactly. i mean, you know, mike francesca called paternity leave a gimmick and scam because his own radio station offers ten days of paternal leave. say it, let everyone come back to you and say you're completely wrong. >> and it really helps prioritize fatherhood, right? >> oh, yes. >> there's so many kids growing up without fathers. what an example this guy is to say, you know what, i'm an mlb

player, yes. but i am a father first, yes. >> you know, family, we all -- working moms, working dads, we want to be great parents and great employees. and great companies the mets being one of them, and the players union giving him the benefit in negotiating this, it's a step towards allows them to be both. >> all right. >> i was surprised that he only got three days. that to me was a surprise. you only get three days coming into the world. >> it's 1% of the season. 1%. it's okay. it's all right. >> very good point. >> jennifer owens, thank you so much for being part of the conversation. >> thanks for having me. >> thank you so much for starting your morning with us. >> we've got a lot more ahead coming up in the next hour of "new day" which starts right now. you don't even have to get out of bed, it's a saturday.

whoo-hoo. i'm christi paul. >> i'm victor blackwell. this could be the most crucial day of search for malaysia airlines 370. >> within hours the pinger that could lead searchers to that plane's black box could go silent. once that signal ends the best chance of finding the plane could be gone as well. >> and this could be a different search. 11 ships and 13 planes are looking on the surface of the indian ocean. under water, two ships the "hms echo" and the "ocean field" they're trying to hear the sonar placed under water now. >> pings you're hearing right now. >> and a submarine is under the surface "hms tireless." >> there's a pilot's simulator that has turned up, quote,

curious findings. no smoking gun, though. the simulator is what you might expect a professional pilot to use. we don't know how unusual it is. >> how curious is it. all of this comes four weeks to the day after the plane has vanished and adds to the mystery. >> specifically focused on 150-mile tract in the zone. officials are using that high-tech equipment with luck hopefully will help them find debris. >> cnn's jim clancy is live in kuala lumpur. what comes out to me, today no announcement of any lead, no major satellite images. just new ministerial committees. what stands out to you? >> what stands out to me is we're going through bureaucracy of this information. we're talking about an independent panel which would

still be controlled by malaysia but would include countries like australia, china, the u.s., uk, and france as well as others. looks very international, looks very independent. but the object of an investigation has to be to be to find some results. and so far, we're not getting any results. we tried to go through with hishammuddin hussein, the acting transport minister, give us a better idea, precisely what the chinese families have, draw us a picture where this plane went and how they did it. instead, we're learning different things, we're learning, for instance, yes, some people have listened to the audiotapes of the cockpits that knew both pilots, colleagues, friends but still no definitive answer who said "good night, malaysia 370." we heard that defense secretary chuck hagel is ready to kwpt.

kwpt. still no one saying what happened to this plane. what would give information of what the intent was to turn right around and made a beeline to antarctica. and we need more than just a little luck to find the pingers because it's vast. let me play out one part here of what was said today. >> malaysia has already asked australia to be accredited to the investigation team, and they have accepted. we will also imconclude china, the united states, the united kingdom and france. as accredited representatives to the investigation team. along with other countries that we feel are in a position to help.

>> now, already victor, christi, we have almost all those countries directly involved, australia to be sure. the faa, the ntsb, people, the fbi, here in kuala lumpur all involved but we're not hearing back just what they're getting out of their investigation. nothing solid in terms of evidence. that's not encouraging. back to you. >> no, not at all. especially for those families still waiting. jim clancy in kuala lumpur this morning. jim, thank you. and investigators who really hope the pilot's flight simulator, you might remember, might turn up useful information. they focused on this thing. and now they say that hard drive did lead to some, quote, curious findings but no definitive answers. pamela brown is joining us by phone right now. pamela, i know you talked to some folks there. what did they mean by curious, did they elaborate? >> reporter: yeah, one of my sores here has first hand knowledge of the investigation

said after combing through the five hard drives from the co-pilot and pilot, that there were some curious findings but nothing that jumped out from investigation that would be information that would indicate a clear motive. according to my source, there were searches, web searches, from the captain about flight emergencies. what to do during flight emergencies. these are just examples. what would you do if there was a fire in the back of plane? what would you do if there was decompression? those aren't specific examples that were searched necessarily. it was those kind of searches. given the context of the missing plane, that might have raised eyebrows initially but my source is that these are also searches that any experienced professional pilot would likely do. and also, investigators found alternate routes that were programmed into the captain's simulator. routes that he would not normally fly, as well as emergency routes from kuala lumpur to beijing.

again, in an event of emergency, where with the nearest airport be. but in the context this is a pilot who what more than 18,000 hours of experience, it's not abnormal that those -- you know, that those be programs into the simulator. >> argument. all right. pamela brown, we appreciate it. >> we've learned some elements about the hard drive. but as discussed in the news conference, malaysian officials have denied a request from the families to release the audio recordings from at least the air traffic control side of the conversations with the cockpit. let's bring in steve wallace. he's the former director of the faa's office of investigation. >> we appreciate you be here. good morning. authorities say because the investigation is still active, that's why they're not going to release the recordings, not even to the pilot's family. in your opinion, do you think

they should do so? >> well, you know, jim clancy made a very good point. this investigation it has lacked transparency from day one. and to hear the defense minister this morning, four weeks after this airplane disappeared announced that we have accredited representatives of these countries. in a modern western day investigation this would happen on day one. you might add some parties later, but the country of manufacturer, country of operator, countries that bring expertise, they're accredited on day one and it's a transparent investigation. as far as air traffic control tapes, in the united states, the faa has the tapes, they run the air traffic control system. they will withhold the public release of those tapes until the ntsb says we don't need to keep them secret any longer for the investigation. this typically is just a few days. and so we would release them not just to the families, but even to the public, hold an event

where you could listen to the air traffic control tapes. this is not the cockpit voice tape on the recorder. that's an spirentirely differen matter. >> i'm sure, steve, you heard hishammuddin saying i convinced them to release the transcript. you told the producer, i've got the quote here, there's this endless pattern from the malaysians that damages the credibility of the investigation. do you believe that this endless pattern has created damage that is is irrepairable? >> well, i would say it's irreparable in terms of the suffering of these families which we have seen so graphically. and because that's -- you can't recover that. is it -- it's probably not irreparable in terms of ultimately finding out the cause of this accident. but the lack of transparency with these families and the

whole handling, you know, there should have been -- privacy should have been protected. they should have been given kind of advanced briefings on things, that's -- that, i think is not ever going to be fully recoverable. >> you know, a lot has been made, too, of the signoff, that it was different than we actually thought that they actually said good night malaysia 37. why would there be a discrepancy this many weeks later and why is it important? >> well, it's just another example of what we've been talking about that there is a transparency. this is not rocket science. you release the tape. sometimes, air traffic communications garbled, so they you get a bunch of experts to listen to it and give their best opinion of what that says. early on in the investigation, i was handed a transcript. i'm a pilot.

it's it was preposterous on its face. it was translated into different languages. and let me add one quick little point, pam brown talked about the simulator, and i have to say, and i haven't really found anything definitive as they said. but to divert this airplane to some remote location is extremely easy for a pilot trained in that flight management system. so it wouldn't really take any practice. i wouldn't expect to find, you know, a diversion in the middle. indian ocean in this pilot's simulator. >> all right. steve wallace, former director of the faa's office of accident investigation. thanks for joining us this morning, steve. >> thank you, victor, christi. >> thank you, sir. much more on the search ahead. but we do want to talk about the fact that investigators say it's an argument that may have led to the ft. hood shooting. something else you may have been watching so closely this week. the big question, what is that

argument about? plus, a lot of kids will go out and have these chicken nuggets but there's a major recall you need to know about. when it comes to good nutrition, my daughter's an expert. hi dad. she's a dietitian. and back when i wasn't eating right, she got me drinking boost. it's got a great taste, and it helps give me the nutrition i was missing. helping me stay more like me.

all right. 14 minutes past the hour. we're going to get back to the coverage of the missing malaysia flight 370. because it's a crucial day that the pinger from that black box could go silent this morning. but there are other things you need to know about. primarily for all you chicken nugget eaters, and we know there are a lot of you out there. tyson is recalling more than 75,000 pounds of popular chicken nuggets. >> customers complained of finding bits of plastic in the food. the recall is for only five-pound bags sold at sam's

ft. hood had a different statement. >> we me of that the immediate precipitating factor was more likely of ans indicated argument in the unit area, but we're still conducting that investigation. >> reporter: what we do know about the details about this verbal at indication, that ivan lopez came to this base sometime on wednesday afternoon asking for a leave request form. when he was told to come back a day later, that's when things unraveled. there's still no clear motive here, army officials are telling us that altercation is germane to their investigation. >> nick, you talked to some there, what are they saying? >> reporter: some are coming saying this is a great base.

there are others who talk about the military. speak of low morale. one soldier called this the black hole and said she wasn't surprised that a shooting happened here. senator ted cruz gave a press conference. and i asked him about that, though he did stop to answer a question. he really didn't answer the question. i sort of pressed him on that, at which point, his handlers just whisked him away. there are people in this community victor and christi, that aren't really surprised that a shooting happened here. this community is haunted by that 2005 shooting of major nidal hasan, when you speak to people in the community, there are those are who not shocked this happened. >> cnn's nick valencia, we appreciate it it. going from nick to jennifer gray right now. finding out what's going on with the weather. >> hey, guys, coming up in a little bit, we're going to talk about the area in the search zone, and we're lucky in one regard that the search zone has actually moved.

you know, one of the pivotal hours of the search for flight 370 right now because there say chance that the pinger in that black box is going to stop pinging within hours at this point, as far as we know. and to make it worse, there's a tropical storm brewing. >> weather could be a big problem. let's get more from cnn meteorologist jennifer gray. jennifer, there aren't many

factors that are helping these searchers, but now wet weather could help? >> yeah, luckily, the tropical cyclone is outside of this search area. if it moves anywhere to the west, yeah, it could be trouble. the cyclone is brewing and heading to the south but a lot of time when you say get the tropical systems it kind of sucks all the energy towards its center so there's actually better weather away from it. so that's what we're seeing, actually clear skies in the area and not much in the form of rain. this tropical cyclone is going to slide down to the south and east for the next couple of days. we'll see cloud cover across the area but we're really not going to see much rain there so visibility might be limited from the air, but as far as the seas are concerned, the roughest weather will be outside to the west. this thing is only packing 50-mile-per-hour winds that's right at the center. and we've seen winds greater than that just on a normal

stormy day. the winds look to be in the 20 to 30-mile-per-hour range. a lot of the search areas winds will be less than 20, so that's very good news as far as the search area goes, guys. so the tropical cyclone, yes, it is to the west. but right now, not directly affecting that search area. may get a couple of swells, but as far as that's concerned, that's pretty much it. >> jennifer gray, even those as well as don't help. thank you. right now, a big part of the effort to find the missing malaysia airliner lies on, i'm hearing those pings as we were talking about, and the batteries as we said could die within hours at this point if they're not dead already even. >> yeah, it's possible. ten days ago. cnn aviation correspondent rene marsh has more for us. rene, good morning. >> reporter: christi and victor, as the ship moves under water, two ships the australian "ocean

shield" and "hms echo" are inching along at 2 to 3 miles per hour. "the ocean shield" is equipped with a pinger locator which is towed behind the vessel. it detects pings from the plane's black box's in water in as deep as 20,000 feet. but this specific mission could be futile. the manufacturers of the black box tells cnn they were due for a maintenance overhaul and new batteries in 2012 but they were never returned for the fix. now, that could mean three things, malaysia airlines replaced the old pingers, had the maintenance done some place else or had outdated pingers. if they were outdated, they'd have a shorter battery life and wouldn't last 30 days as required. >> rene marsh there for us. rene, thank you so much. >> and searchers, as you know,

are hoping to find flight 370 deep under the indian ocean and using different perspectives to do so today. >> if they do, how hard will it be to bring the wreckage to the surface. more than 10,000 feet deep this water is. we'll have more next. udes my fico® credit score. yup, you get it free each month to help you avoid surprises with your credit. good. i hate surprises. surprise! at discover, we treat you like you'd treat you. get the it card and see your fico® credit score. man: i don't know...i forget. it last time? scott: hello, neighbors. man: hey, scott... perfect timing. scott: feeding your lawn need not be so difficult. get a load of this bad boy. man: sweet! scott: this snap spreader system from scotts makes caring for your lawn snapcrackin' simple, guaranteed. just take the handy, no-mess bag, then snap, lock and go. to see a demo of the snap spreader, go to scotts.com. feed your lawn. feed it! anncr: visit scotts.com/goyard for the chance to win a $25,000 backyard makeover.

leadership" a president's private diplomacy." well, this morning, 11 ships, 13 planes, all frantically searching for flight 370. and australia's prime minister says the search is, quote, the most difficult in human history. even if the wreckage is found, you wonder how much of this plane could be salvaged. randi kaye looks at the technology and the challenges involved in that. >> reporter: this is what it looks like trying to recover an airplane in the ocean. you're watchg a u.s. navy salvage team gather piece of flight twa flight 400 which went down in new york in 1986. here, divers are trying to maneuver between wreckage. >> the u.s. navy has recovered a helicopter from 17,000 feet. they have the capability. >> reporter: retired navy captain chip mccord has been involved in at least 50 salvage operations including twa 400 and

swiss air flight 1100 had krooshed in 1998 off the coast of nova scotia. those were both in waters shallower than the indian ocean. but they can go as deep as 20,000 feet, but the deeper the recovery, the slower the process. >> it takes about 1,000 -- an hour for every thousand feet you that need to descend. so if you're going to 11,000 feet, you can count on 11 hours to get down. >> reporter: at 0 those depth it's pitch black, so the underwater vehicles are equipped with lights and cameras. they're also outfitted with sonar to scout for debris. they are steered by two operators on board the ship above who use instant feedback from the salvage vehicle cameras to direct robotic arms. >> they can hover, they can move left, right, forward and back.

and go to where they need, very carefully hover over a piece and pick it up if they need to. >> reporter: remember air france flight 447 which crashed in the atlantic ocean in 2009? two years later, an unmanned underwater vehicle found the debris field for that flight, 13,000 feet beneath the surface. the engines were pulled from the ocean floor. if flight 370 was found, search teams are prepared to do the same. >> if it's small like the black boxes you can put a little basket on the rov and the arms can put it in the basket. >> reporter: but the remote underwater vehicles can only carry about 4,000 pounds. so anything heavier like a large piece of a fuselage will have to be attached to a cable and pulled to the surface by a crane on a ship. keep in mind, this could be happening miles below the surface, an incredibly difficult task. still, no doubt, salvage teams will keep their eyes peeled for

the black box, hoping to get much needed answers first. randi kaye, cnn, new york. >> announcer: this is cnn breaking news. all right. we're going to continue the conversation now. we've got breaking news in from the chinese state news agency xinhua, that chinese patrol ship searching the area of the indian ocean has detected a pulse signal. >> a pulse signal. >> a pulse signal. that's as much as we know about this. so let's bring in an expert who can tell us more, simon boxwell, oceanographer with the nationalography center. >> let me ask you, simon, we're hearing this is a pulse signal with a frequency of 37.5 kilohertz per second in the indian ocean, does that mean anything to you? >> without hearing any more

detail, this just came through, i've just heard it, i'll be astounded if they come across the pinger, it really is looking for a needle in a field of haystacks. problem is, they could be picking up signal pings from other ships in the area. if they have located the pinger, it would be fantastic, but of course, being here before with satellite images they're in an entirely different part of the ocean or wrong region so let's hope this is a sign, if this is the pinger, that it's a doable recovery in the 21st century, the biggest problem is retrieving wreckage in the first place. this region is huge, it's bigger than the great lakes of north america, in terms of its coverage. and the chances of finding is about same as winning the national lottery. i mean, it's fantastic if

they've located it, but i have to see more data. >> we welcome our viewers who are joining us from around the world as we now simulcast on cnn's international network. we're talking with simon boxwell who is an oceanographer with the national oceanography center. the question is, if not a pinger from a black box, simon, what else could send up this pulse signal, that according to the chinese state news agency xinhua a chinese patrol ship has detected in the south indian ocean? >> well, a lot of equipment we deploy in the oceans, scientists want to find a ping. we know one uses pingers to transmit sound data, so we can focus in on our equipment. there are, as we heard, a lot of shims all using acoustic

systems. while i'm not dismissing this as a positive, i'd need more information in homing in on where that signal is found. >> if you do find something with this locator that they've been talk about, again, this is a ship, this is not the pinger locator necessarily, will they divert where that pinger locater is to be closer to this chinese ship? >> that would be the thing to do, you know, if they get more information from them. the advantage of the two ships out there, hms "echo" and "ocean shield," hms echo is used a field-based system. it would be essential to get them onsite because they have the ability to look at the date it. if it's still sending out a signal that the chinese ship can detect, as long as they can get there quickly, we don't know how

far apart these frontcoum the ce ships. we have to wait and see. >> simon i think you used the word a moment ago that you would be astounded if indeed this ping is from one of the black boxes because the odds are stacked against all of these crews that are searching having no sight of debris. because the depth of the water, the terrain there below the water, and all of that can get in the way of sending out a signal that's only detectable at what, one or two nautical miles? >> yeah, at most. bear in mind, that the terrain is between 10,000 and 15,000 feet deep. so it's different than the terrain they were looking at, say, ten days ago. it's a much more complex terrain, much deeper in parts. so they've got to be right on top of it. the chinese ship is likely to

having there with the "ocean shield" if they can get closer they can get away from the surface and also distinguish it from other equipment, other ocean noises and the noise from the actual transponder on the black box. so my guess is, if this information is as it says it is when if they can get one of those two ships much closer to the location of the chinese ship, they may have stumbled across the black box. but as you said, they've got to be pretty much on top of it. and the chances of that are phenomenally slim but they might. >> so i have a tweet here from john. and i thought about it when you said they haven't even found any debris. they haven't definitively found any debris. he had tweeted is it possible that the flight landed perfectly on top of the water, "sully" style, as it's now being called, thus says you have no debris?

how plausible is that? >> given the sea conditions in this area, you know, whether that plane landed safely on the water, it was flat calm. we know when the plane went down in the southern indian ocean, it wasn't flat calm. it's likely to be an uncontrolled landing. the probability is it would have broke up on landing. why isn't there debris in the area? that debris can move quite a distance and we know that debris can disperse through many different directions. along with that, saturated and sink away with air pockets trapping the air, making, say, wing sections or whatever will the low, with the storms they've had over the last few weeks that would tend to knock the air out of it. so any surface debris will disfuse and disperse.

>> chinese state news agency xinhua is reporting that a chinese patrol ship searching an area of the south indian ocean has detected a pulse signal with a frequency of 37.5 kilohertz per second. so we are, of course, trying to determine, working to determine, as they are, if that pulse is from the pinger of the black box. and we happen to have one here courtesy of g.a. telesis, a company in south florida. guys, if you can take it to it. i want to show where the pinger is. the pinger is in the front of the black box. it's the cylinder. the white cylinder up front here. that is what is emitting the ping, the blue pin 21, tpl and locators are searching for, that battery expected to day, if it held for 30 days, within a few hours of now.

although some analysts say it could have died several days ago or could last a few more days. you see in the center, this silver dot here, that is the center. once this is submerged in the water, that is the sensor for the ping tore send off a ping. and it pings once per second for 30 days if the battery life holds. we know as the battery starts to die, that ping, according to the manufacturer of the beacon will start to get weak and less frequent. so right now, this is the very crucial period, if it had 30 days that 30 days is up this afternoon. >> this afternoon. that is, again, if this pulse turns out to be anything, absolutely extraordinary. somebody who has been passionate about this is richard quest. he has followed this. he's done his research. he's on the phone with us right now. richard, what do you make of latest information that the chinese patrol ship has discovered a pulse signal in the southern indian ocean. >> well, i think first of all, you have to note the 37.5 hertz

signal that they're being specific about saying because that is the frequency upon which this pinger is supposed to be transmitting. so from that point of view, you know, they haven't just heard something. they've heard what they believe to be the right frequency of 37.5 kilohertz per second in the south indian ocean. and the also it's widely understand that can the chinese ship involved has been very much concerned in the efforts to detect the signal of the black box. it arrived friday, north of the area where everybody has been searching. at the th if they have found it, and bearing in mind, we're not entirely sure what equipment anyone has on board, this would be a remarkable finding, indeed. and this would be quite

extraordinary. we don't, for example, what pinger location equipment it's got on board. we know the "ocean shield" but we don't know what it has on board. one other point, and i'm going to be a little skeptical on this, of course. you'll remember, it was the chinese that brought out the satellite photographs very early on in the investigation. very early on in the investigation which turned out to be in the wrong part of the -- in the northern part of the south china sea, exactly the location from where the search is taking place. >> richard, the blue pin 21, the towed pinger locator, in the water, what speed, and how long will it take to get the sources below water to the site to see if they can zero in on where

this can be? >> first of all, i'm not sure the distance where between the one is claiming to be and where the "ocean shield" is located. we know that the actual searching operation, we know that that searching operation is very slow. a mere couple miles per hour. and that's because of the nature of the waves, the way the search has to be done. all sorts of reasons that are, frankly, way beyond me. but the experts have said, it has to be done at a very slow speed. and i keep coming back to this, because it is the most remarkable announcement this morning. the fact that, you know, the chinese patrol ship is saying it's discovered a pulse signal with a frequency of 37.5 per second is quite remarkable. if it proves to be solid then you can guarantee every resource, every ship, every plane will be heading in that

direction asap. >> all right. hey, listen, we've got mary schiavo on the phone right now. mary, again -- i'm sorry, she's live with us, i believe. mary, thank you for being with us so quickly, as we get to this new news that we're getting in. again, i just want to reiterate to the news we got in, chinese patrol ship "hasom one," and they have detected a signal, we're just getting word of it. this does not mean what they have found is the black box. >> we should also say this is according to the chinese news agency xinhua. >> right. so, mary, what do you make of the news this morning? >> it's highly significant because it's the right hertz.

the frequency. you can pick up signals from engines and machineries and ships. various things have pulses. the pulse and frequency was picked because it's not just something that appears in different things. finding a 37.5 kilohertz pulse is significant because that is the black box pulse. that's the pulse they're looking for. so it may or may not be it. but it's the right frequency. so it's something they have to put their assets there right now and go find whatever that is because it's the right frequency. >> let's go to jim clancy joining us live from kuala lumpur. jim, after this morning's news conference, it seems as you called it, more about bureaucracy about the search. and now this source, according to chinese news agency xinhua, a chinese patrol ship is finding this pulse signal developments on the search front? >> reporter: well, i think you

have to look at it with caution. this has been reported by xinhua, it has not been confirmed by the australian joint center working on all of this trying to coordinate everything. we have to wait and see what comes out of it. it would indeed be extraordinary if they are able to have located from the pinger from the aircraft itself. hopeful -- certainly. it's going to raise a lot of people's hopes but i really need to see it confirmed by someone else. i need to see confirmed again by the chinese, in order to determine how much credibility we should put into it. victor? >> simon box all, we don't know how deep it was when the news is coming out, you had said yes, it makes sense to divert where are they are now to be closer to the

ship. how long do you think that might take? >> it depends entirely on how further away. if the ships were in the southern section of the search area, it could take them 12 to 24 hours to get there. and in that time, the data could have stopped transmitting. you got to bear in mind, 37.5 kill ahertz, it's a fairly common pinger used in the ocean. so it's not unique. it could be a variety of things with the signal, i'd really like to see, as i said earlier, we've had a lot of red herrings, hype hyperbo hyperbowla on the whole search and it would be fantastic if this is it, but there are lots of other things that could be

giving a false signal. and it will take -- it could take some hours, or even a day, for one or two of those ships to get onsite to focus in on what the signal >> for those joining us around the world, we have jim clancy in kuala lumpur and former inspector general mary schiavo here with us as well and simon boxall, who is an oceanographer. reported by chinese xinhua, a news agency. i want to be clear about what they are reporting here, a pulse detected. a pulse signal in the south indian ocean at 37.5 kilohertz. we learned from our richard quest, that is the frequency in which the pinger, we have one here on the flight data recorder out of a jet, that is the

frequency at which the ping is emitted. but we want to be very careful here. it has not yet been confirmed that ping at 37.5 kilohertz is from a flight data recorder. we know there will be, of course, an effort now to confirm that as more resources are flooded into that area. >> as long as that continues to go forward. are we taking a break, guys? or keep talking. we will take a quick break as we continue to get some information. we will bring you full coverage with our team all over the world. stay close.

>> announcer: this is cnn breaking news. according to state news agency xinhua in china, something has been detected. it is specifically a pulse signal. this was detected by a chinese patrol ship. this could change things, if it turns out to be anything, we need to clarify, we do not know if this is even a flight data recorder from any sort of plane. this is what is very interesting about the information coming in this morning. according to the state news agency xinhua, the chinese patrol ship in the indian ocean, detected a pulse signal of 37.5 kilohertz. we have confirmed from the president of the pinger manufacturer that this is the standard beacon frequency. we do not know if it is from any black box of any sort. that still has to be determined. however, the fact it is the same

frequency is significant in this particular situation. we have all kinds of resources with us here this morning to walk us through what's happening. >> we have jim clancy in kuala lumpur and former inspector general with the u.s. transportation department mary schiavo and simon boxall the oceanographer. we have all of the resources used by scientists and military that would emit signals. that it is 37.5 is significant in this conversation. >> we need to confirm they have measured it correctly and there are other standard pingers. pingers are tuned to this frequency. this is a compromise between maximum distance and frequency. it is not an uncommon frequency to use from beacons. you need to know what else is

out there and one would want, certainly, confirmation of the signals. the signals should be secured. they need to locate this as a positive sighting. if and that is a huge if this pinger proves to be the pinger, the possibility of recovering the plane, or at least the blacks box goes from being 1 in a million to almost certain. >> the interesting thing about this, as you say, this is a huge if, but if it does happen, we are at the very end of the life span of this thing. it disappeared 30 days ago and it is at the 30-day mark right now where this black box very well may die out, so to speak. mary, can you talk to us at all

about these pingers that are in the ocean. this is such a difficult search because you are talking about underwater. we think about ground robots. this is under water. we are dealing with ground robots. they are talking about two dimensions. when you talk about under the water, this is truly a three dimensional search. >> that's right. depending upon, obviously the strength of the battery and age of the black box and pinger, the range is between a half mile all the way up to three miles or perhaps beyond. that is from the ocean floor up and then the side distance, too. you are working off angles no matter how you cut it. given it is only at maximum, a three-mile radius. that is pretty close to the surface, which it would not be. if it is a pinger, they have a pretty good fix on the location.

if the pinger battery dies out, now they have a location fix in which to search. they can deploy all the other wonderful resources that the other guest was telling us about, the side-scan sonar, et cetera. this is a hugely wonderful development. i think we were talking yesterday what they needed right now is a huge dose of luck. maybe they got it or maybe they just had a lot of hard work going in by the particular ship and had a theory of where to look. it is the right frequency. it doesn't occur in nature. it is not nature giving off that frequency. supposedly there is nothing else out there in the ocean except the ships. i'm encouraged and i would put resource there is as soon as possible. >> let's join another expert voice. we have retired navy captain chip mccord. he has been involved in the

salvage of twa flight 800 and swiss air flight 100. he joins us from boston via skype. what do you make of the chinese news agency xinhua this morning about the pulse detected in the south indian ocean. >> well, that is great news, if it is. like mary said, luck plays a lot in these. in any investigation, there is always a lot of news that comes out and not everything is backed up. this is from the state agency, the newspaper. the commander organizing the search effort hopefully is in contact with the people who detected it and getting all the information and location and what they were using and how they did it. whether or not they can pinpoint a location on it. >> okay. what about the possibility that somebody else was just conducting a test of their

beacon? >> it's a possibility. i don't know who is in the area and who would want to do that in that area. it is a pretty remote area. there is not a lot of shipping in the area. i'm not sure who would be doing that. >> do we still have jim clancy in kuala lumpur? jim, has there been any reaction from malaysian authorities? >> 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 from the ceo of malaysia airlines. >> the hope the battery life would have lasted longer than 30 days, which is forecast for most of the flight data recorders. mary schiavo, i want to go to you with this because we were sitting in these positions in these seats two weeks ago saturday morning when the acting transportation minister held up the paper and said the chinese through the satellite technology

detected the images in the water and the announcement would come later. that announcement never came and they found no credible leads. wait and see is the phrase jim clancy used and i think that is very important. >> wait and see, certainly, but wait and see and send assets and ships and people over there as soon as possible is my m.o. because this is the only break that anybody's had for a very long time. it is just too right on the money in terms of the frequency, the megahertz, it's too close to what it should be. it is exactly what it should be if it is a pinger, to overlook. it would not be a freak thing in nature. you just wouldn't pick up that frequency from a whale or anything like that. so, yes, don't be putting all of

our hopes in that one area yet, but boy i would sent the ships their right now. >> retired lieutenant colonel michael kay is with us. lieutenant, thank you for being with us. what do you make of the latest information? let me set it here for you. we do have a report from the state news agency in china, xinhua, a chinese patrol ship is detecting a pulse signal at the frequency of 37.5 kilohertz. what do you make of that this morning? >> look, in a four-week long investigation that has given us absolutely no clues, this is potentially sizable information. from that respect, i think all of the discourse that we're hearing is sensible and objective. what i would say is that if we look at the beginning of the investigation and the way the information was disseminated, i think it could have been done better. now the australians have taken leadership on the international

side, thii think the global community with the information that is driven through the coordination cell. that is key when it comes to dissemination, but also release. which information will you release? i'm slightly concerned this has come from a chinese news agency. i would like to see corroborated evidence coming from the joint agency coordination center in australia. until we get absolutely something clinical from them, we should be very cautious about this. i also would be looking at the 150 mile tracks. if, indeed, this 37.5 kilohertz has been found on one of those two converging tracks, it is again more positive evidence. we heard about the imarsat evidence with the 250-mile tracks. that is good news if it is

coming from those tracks. mary talked about the overall assets. we need the p-3s and p-8s and get them over all areas to try to cooperate. can we see anything that would link the black boxes in the areas we are looking in? any cooperation or debris to confirm that evidence. there is a long way to go before we get anything definitive. this is potentially good. >> lieutenant colonel michael kay, you brought up a good point. you are hoping for that effort. >> reporter: authorities at the joint collaboration center here in perth saying they are unable to confirm this xinhua news

report. i'm sure they are working to try to figure out what this is all about. this has been a 24-hour search operation today. a total of 13 planes and 11 vessels searching the area the size of ireland. including a 150-mile long track that team of international experts identified as the most probable place that the plane went down. no word if the pinging had been heard in that particular area. we are working to get more information and we will get it to you as soon as we can. >> chip mccord? i want to go back to chip mccord, the retired navy captain. you know what we are talking about when we talk about the search of this magnitude. i wonder how much do you think because victor was saying, there is a lot of skepticism coming

from investigators and from the public regarding what the investigators are saying. how much do you think investigators know that they are not telling us? >> well, there is a lot of information that comes in in these types of investigations. before they put things out publicly, they want to verify they actually have some facts in hand. just like this report from the chinese news agency. the folks in australia will want to verify it and talk to the people on the ship to understand what they are talking about. something could have been lost in transmitting from the ship to the chinese news agency. i'm not saying it is. what i'm saying is it is very important to make sure that you know what you are saying is a fact before you release it to the public. >> all right. we will take a break here, guys, back in the control room or can we continue? we will take a break.

we have our resources around the world in kuala lumpur and perth. simon boxall joining us and mary schiavo. we will continue to report on the breaking news reported by the chinese news agency xinhua, that the patrol ship discovered a pulse signal of 37.5 kilohertz that would match a flight data recorder. it has not been confirmed to have come from a flight data recorder. stay here with cnn. we will continue with the coverage in just a moment. hi she's a dietitian. and back when i wasn't eating right, she got me drinking boost. it's got a great taste, and it helps give me the nutrition i was missing. helping me stay more like me.

signal. what is interesting about it, it has the frequency they sent out of 37.5 kilohertz. that is the standard beacon frequency. we do not know that this has anything to do with malaysia 370. nothing here has been confirmed. the other information that came out that is so interesting now, too, as we just gotten this update again from xinhua, they are saying that a black box detector deployed by the haxon one picked up the signal 25 degrees south latitude and east longitude. it has yet to be established if it is related to the missing jet. we have a locator now. >> our teams are working to see if it is in the search area. >> victor and i were both interested to hear. we knew there were two black box detecto detectors. >> the blue fin 21 and the ocean

shield and towed locater pinger. i'm coming to michael kay, if we knew it had a black box detector it could deploy, had that been disclosed up to that point? >> that is a good question. the only assets i was aware of that had the ping locators were the echo and ocean shield. that has some very, very technical active and passive sonar equipment that if t has bn using. it might be the chinese ship had active or passive sonar that was listening to the 37.5 kilohertz pulse on. i'm not sure you need a ping locator to be able to pick up that 37.5 kilohertz pulse. it is quite conceivable that a passive sonar could be able to do that. >> all right. i just want to give a question

here. the hiscuan-1 is the ship. mary schiavo, we're told there are two, now we're hearing this is a third ship that has some sort of black box detection equipment on it. is this indicative, do you think, of -- how do i say it? >> the hesistance to share -- >> and really discombobulated structured set of information not just going to the public, but to each ship and each country involved together? >> well, i think so. i think we heard from the manufacturer earlier in the week on cnn that in the whole world, there were only five of these towed pinger locaters.

there weren't many, but two deployed there. a lot of us were saying where are the other three and where are they being used and why can't they be deployed? it is possible they managed to get some of the others that are out there in the world, but you do have to wonder why, if the chinese had the resource they didn't tell the task force unless for some reason they got it in recently or were in a hurry to get it in the water. there are always excuses for why they maybe didn't coordinate this, if that is how they did it. there are other ways as i mentioned to pick up the frequency. you have to be pretty close to it or right on it because like i said, the signal is a strength of three miles. 1.5 miles depth and 3 miles lateral. you have to be pretty close. if that is where the ship was, it was almost on top of it. presumably, that is a good

indication of where it is whereas the towed locator pinger has the ability to pick up better than other equipment. we don't know. certainly i hadn't heard and had been watching closely of additional pinger locate eors coming to the area. australians who are heading to the investigation are frantic to find out the information and getting assets there. >> retired navy captain chip mccord, involved in more than 50 ocean salvages with the twa 800 and swiss air 100. they are searching for the debris field and any part of the plane, if, indeed, it did crash in the south indian ocean. if this is the data recorder,

how confident is it to find the recorder before the debris of the crash? >> that is very rare. normally you start with the wre wreckage of the surface on the ocean. you back it up with tides and trying to predict an impact point and you start the search. this one we never had any of that. the ability to find the towed pinger locator to show what a tremendous job they did on refining that data to be able to predict the path. i want to say, again, this is the one blurb in the chinese news release in the command structure will have to investigate to find it to verify it. >> chip, very good point. i was going to take that point to michael kay. you have to think there are

families who are watching this. families who have been all over the spectrum with grief, with hope, with fear. what would you say to them, especially, you know with the majority of passengers and china and now this is coming from the state news agency there, xinhua, what would you say to families as we wait for word of the pulse signal that they picked up? >> the next piece of information that air chief marshal releases and he is the guy leading the ship from the joint coordination cell. the next bit of information he releases has to be unhe kw unequivocal. that is the first point. the second point is that the

whole dissemination of the piece has moved for the better as the investigation progressed. it is absolutely key that the air chief marshal jumps on anyone at this point, if there is anything linked to 370, it comes through the coordination center and doesn't get leaked out. if it gets leaked out as we hear from the chinese news agency, it will just give false storms to those friends and family who are waiting for this piece of information. we have three phases. it is the where, which is what we are doing the last three weeks. the what and that information could be accessed quickly. and the information and we have been talking about theories over the last four weeks. we are in phase one at the moment. the key piece is to get the

unequivocal to give families closure. that is priority number one. >> retired lieutenant colonel michael kay, stay with us. everyone else, stay with us. we will take a quick break. we will continue with the breaking news reported by the chinese state news agency xinhua, the chinese patrol ship has detected a pulse signal there in a search area of the south indian ocean. we are working on a map to show you exactly where this is. we will have more after this.

>> announcer: this is cnn breaking news. and the breaking news at this hour, if you are just joining us here in the u.s. or the world, the chinese state news agency xinhua reported the patrol ship is looking for the wreckage there. the ship haixun has detected the pulse signal of 37.5 kilohertz per second. that is the identical frequency of a pinger on a flight data recorder. it has not yet been confirmed that the frequency is from a flight data recorder, but of course, they are flooding this area with resources. >> in fact, i'm just getting word. there has been some questions about, you know, the chinese news agency xinhua and what they knew and what they didn't. i'm getting word there is a

representative or reporter from that news agency from xinhua that is on the haixun, on this boat. that is where the information is coming from. i want to bring in david suicie. david, you have been watching this for four weeks. we have been hesitant to say this is a big find. we do not know. there is no confirmation. as you hear this, this is a pulse signal that was found off this ship at the frequency of 37.5 kilohertz, which is the standard beacon frequency, what is your first reaction? >> this is a pinger. i have been doing this for a lot of years. i can't think of anything else that could be. they said it is every second and 37.5. that is a pinger frequency and it is a pinger of pulse of every one second.

unless there is another aircraft down in that area, i think we are on to something here. >> could it be testing? could somebody be testing a signal and somebody merged? >> if they are, it is a bad joke. >> the odds, david -- go ahead, i'm sorry. >> you go ahead. that's fine. >> the odds of no debris and the confirmation of the malaysian officials to the last day of the expected 30-day battery life and to go out and hear although there is no confirmation of the joint asset collaboration center, the pinger, the odds of that happening are unbelievable. >> as i said the other night, when we first got that

announceme announcement, that all resources were in place and every piece of equipment they had was out there searching for this thing, that's a point in an investigation where everything starts working together. this synchronicity where everything is working forward and everything has come together and the preparations. that is when miracles happen. i'm really trying to hold back my enthusiasm right now because i have been doing this a lot of years. when things like this happen, it really is exciting for me. >> chip mccord, are you still with us -- i'm sorry. chip mccord, are you still with us? >> i'm still here. >> chip, i wanted to ask you something. we were just getting this information from the xinhua news agency, quote, a black box detector was deployed by the

"haixun." this was not one of the black box detectors from the u.s. that are so technologically advanced. do we know what type of detector is on the ship and how capable or how assured we can be that it picked up something substantial? >> i don't really know what the capabilities of the chinese are with regards to this. again, the report is from the chinese news agency and not from any official on the ship or anybody in australia. although with the previous guest just said, 37.5 kilohertz in a one second or two second burst, that is the frequency and period for beacons on the flight data recorder and cockpit recorders. until we really nail that down and exactly what they have out there and what they detected, i

think it's good we're having discussion, but normally you would not want to release this information until you really got it nailed down and assured you have a fact. >> and just so people know what they are looking for, we have a flight data recorder here in studio. this is not the exact model on board the boeing 777, but they all pretty much have a similar design. what you are seeing is this grayish white cylinder on the front. that is the underwater beacon. that is the pinger. that is what emitting the signal for the last 28 days and hopefully will continue here -- actually four weeks we should say to be precise. you see the silver dot in the center. that is the sensor. when it hits the water, it tells it to start sending off the

ping. one every second. at 37.5 kilohertz per second, which is the frequency at which this pulse has been detected. just so you know what they are looking for and talking about, it is not really big. a little bigger than a shoe box. this could answer the questions about what happened to flight 370. hundreds of parameters in the honeywell model inside this boeing 777 malaysia 370 to tell you the pitch and yaw and speed in which this plane flew. this gives the technical information. also another black box, also orange, similar design, that tells you all of the audio recordi recordings. the last two hours from the cockpit recorder which has its own pinger. if it is a pinger, it could be from either one of those two black boxes. >> our retired navy captain chip mccord, we go back to you and we

talk about how challenging this is to try to find anything, specifically this black box. i hope you can walk us through it. we were talking earlier, you have the ground-based robots. this is an underwater robot. you have the ground-based robot. they have the surface and that's it. that's all they deal with in that space. you have the underwater robot. it has extreme pressures. can you walk us through the technology? >> sure. when you are looking for the pinger in the towed pinger, the u.s. navy provided. they are towed behind the ship. they want to get down deep to get below any thermal layers of difference of temperatures and that could affect the propagation of the sound from

the pinger. once you can detect it with the towed pinger locators, they run a course perpendicular to the one they detect on and the two lines of bearing and those will pinpoint accurately where they are. they have to know where the locator is so they know the cable and the depth. they have a pretty good accurate idea of where in the world that towed pinger locator is using gps. the next things is with side-scan sonar. the deeper into the ocean, the more pressure it gets and the beefier you make your systems. these pingers are rated to 20,000 feet which is about 98% of the ocean. if it went into some trench,

which is deeper than 20,000 feet, those pingers will actually implode. when they go back to the next step of identifying the point from the pinger locator, to do a scan, side-scan sonar to verify how large and make sure it is aircraft wreckage and find out how large the debris field is and from that, they can put down remotely operated vehicles which are tethered by a cord to the surface. going back to the side-scan sonar, those are towed or autonomous vehicle. the final step is going down with a remote-operated vehicle with a cable and the vehicle goes to the bottom. the deeper it goes, the bigger the vehicle has to get because of the pressure. that vehicle with cameras and sonar, would be able to hover around the wreckage and identify various parts of the aircraft. because of the cameras and black boxes are actually bright orange

and if they are out in the open, should be able to find those fairly quickly. >> mary schiavo, considering all we have is this report from the chinese state news agency that this frequency, this pulse signal was detected, and put that in the context of all of the hopes that were dashed of the family members of the last 30 days, do you think it was appropriate for xinhua, as we understand, is on board the "haixun" to release this information before confirming or having any other outside agency to confirm this is a pinger? could this be the biggest hope that will later than dashed for these families? >> well, if it is not the pinger and did not pick up the signal, it would be a terrible -- i

would not call it a hoax, but a terrible thing for the families. this should have gone back to the task force and gone back to his team and look at the data of what they picked up. then they would have much more assurance and when they finally announced it. xinhua could have announced it. i know everybody wants to be first and there wouldn't have been a problem with that. it should have come back to the australian base, the task force, to see if it is a reliable report and if this is really what they picked up. see what form they picked up and how they picked it up. did they pick it up on a simple radio receiver? how did they pick it up so they have some measure of reliability. you know how these things go. the reporter on the ship when they got excited that they picked something up, probably related it back to the news agency and off it went. there wasn't the filter of reliability that you would hope would be on there.

now the families have heard it. if it is not true, the damage has already been done. >> listen. we will take a quick break here. if you are just joining us, just to let you know, we are getting information as you hear us talking about from the state news agency xinhua, who has a representative on board the chinese patrol ship, "haixun 1" that the signal has been detected in the south indian ocean of 37.5 kilohertz which is the standard frequency of a beacon. this is coming from the one source. nothing has been confirmed. we decided to do some digging. we are talking next to the president of dukane seacom. he is telling us we need to be cautious about this information that is coming in. he will tell us why after the short break. stay close.

>> announcer: this is cnn breaking news. the breaking news this hour is that according to the chinese state news agency xinhua, a single pulse was detected. a pulse signal in the south indian ocean in the search for the debris of malaysia airline flight 370. we also know that this ship, "haixun" which detected the pulse has also deployed a black box detector, they are calling it. they are not giving anymore specifics. we know the u.s. equipment there

is the bluefin detector. we know they are looking for the black box, the flight data recorder and the cockpit voice recorder. >> this is possibly the last day. we are in the last few hours that they believe this pinger would continue to emit a signal of any kind because it is 30 days in. secondly, again, this is coming from xinhua, the state news agency in china, they detected a pulse signal, but it has a frequency of 37.5 kilohertz. that is, we do know, the standard beacon frequency. however, a couple of things we did not know, one, we did not know that there was a black box detector on this ship. we were only told of the two black box detectors deployed today from the two other ships that we know of.

ocean shield and echo. that was information we got that we did not know was down there. a lot of people skeptical about what this means and about the fact this has not been confirmed information and about the fact that xinhua is also the news agency that gave us the information several weeks ago that they found what they thought to be debris. it turned out it was not. let's go to our panel here. we have chip mccord, a retired navy captain and michael kay and mary schiavo and jim clancy. jim clancy is in kuala lumpur. mary, mary schiavo, let me go to you. i want to reiterate something victor talked about. it is a question i had. how appropriate is it for the chinese to release this information knowing that the majority of the people on this flight were their nationality or from their country and knowing

the families were so critical of the investigation that they have been on this horrible roller coaster ride of emotions with fear and hope and despair and grief. how much credence do we give to this report until we get some sort of clarification and how appropriate do you think it was for them to release this without more of their investigators being in on it? >> well, it wasn't appropriate at all because they are part of the international joint task force. the task force was formed specifically to make the best effort possible, the biggest push and the best minds and resources in the world, literally, to get this together and get this solved. this kind of information is exactly what they need for the joint task force to look at and get the minds on it to determine what it is. it makes you suspect that obviously the chinese have

technology that they did not share with others. you don't have to share with others. you do have an obligation to share the information with others if you are a member of the joint task force, that's how it works. by the way, in the united states in the ntsb in accident investigation task force and you are a member of the task force and you leak information, you are kicked off the task force, if you talk out of school and you don't share your information with the ntsb first in the accident investigation, you are gone. im sure australia will not do that because if they picked up this pinger, this is an incredible development and they have equipment that is better than anyone knew they had, which would not surprise me at all. then, china would not want folks to know. the reason they would want to release it is because of what you said. the majority of the passengers were chinese and they knew they would be interested and a point of national pride. the china ship found the pinger

and they would want to take credit for that, i assume, for their countrymen and people on board the plane. it doesn't surprise me that they would have something else, but it does surprise me they didn't coordinate with the task force because like i said, that could get you kicked off the task force in the united states. you would. you would be off. >> mary, we have important voice joining the conversation in a moment. speaking of sharing and protocol. i'm read it. the australia defense force learned on saturday at 8:46 p.m. let's say six hours ago, about the chinese report that the haixun patrol ship picked up the pulse frequency of 37.5 kilohertz for the missing malaysia airline plane. the adf expects china to notify malaysia first and notify australia, quote, in a matter of

course, the spokesperson said. the spokesperson also called the chinese report an anomaly of interest. the false positives need to be considered. let's talk about the pinger and signal with the person who makes pingers and not only makes pingers, but the pinger that was installed on the black box of flight 370. we have anish patel joining us on the phone with us from dukane seacom. anish, what do you think of the detection of the single pulse signal? >> good morning, victor and good morning, christi. my degree of skepticism is high. i have to get some cooperation. i would like to see additional assets put on-site quickly.

maybe some sonar buoys on the water quickly. there should be a indication from the voice recorder. if the recorders are adjacent or near each other or reasonable proximi proximity, they should have detected two signals. let's get assets in the water in the area to corroborate before we get hopes up and disappoint families another time. it is the right number. 37.5 kilohertz, that's fantastic. it's the right number. >> what else could it be if not this pinger? what else at 37.5 kilohertz? give us an idea what else is out there that would be emitting that frequency? >> to our knowledge, to my knowledge, it is not a number, it is not a frequency that

readily occurs in nature. dolphins are not talking to each other. this is the unique number and unique frequency. the reason it was chosen is to give that standout quality that does not get interfered with by the background noise that readily occurs in the ocean. >> your question of why not two signals and i heard that from my producer with your conversation with him before coming on air with us. your question of one signal, not two, is basically a signal from each of the black boxes. one from the digital flight data recorder and one from the cockpit voice recorder, is that correct? >> yes. let's recall in air france, one of the beacons was dislodged and damaged and did not produce a signal. ultimately neither beacon was the one that was recovered and did not function. that was two years after being submerged. there could be a host of reasons

why they are not picking up two. that is one of the initial questions i would ask. we should hear two signals. >> you say there is a possibility and you bring up air france of it being dislodged. is it possible the way your beacons are connected to the flight data recorders that they could be picking up a beacon that is not connected to the flight data recorder? >> if an accident happened and damage was done, you are correct, victor, that is a scenario that could happen. the intent of the beacon is to provide a proximate location. if it drifted a bit, you at least would know where the debris field could be. these are designed to find the needle in the haystack, which is the debris field. if we got lucky in this incident and the beacon is used to find the debris field, that is great. at least now we know where to look. >> all right.

we will take a quick break here. i hope want to give you new information we are just hearing. we will go to jim clancy next in kuala lumpur. he has new information regarding the audio recording. to remind you, authorities denied victims' families their request to release the recording from the cockpit. the final audio recordings. they released the transcript. refused to release the actual recordings. jim clancy is getting new information about that. we are going live to him in kuala lumpur in just a moment. stay close. anufacpstate new i tell people it's for the climate. the conditions in new york state are great for business. new york is ranked #2 in the nation for new private sector job creation. and now it's even better because they've introduced startup new york - dozens of tax-free zones where businesses pay no taxes for ten years. you'll get a warm welcome in the new new york. see if your business qualifies at startupny.com

>> announcer: this is cnn breaking news. if this turns out to be true, it will by far, be some of the most extraordinary news we have heard in the last four weeks. the chinese news state agency xinhua reporting a chinese patrol ship, a short while ago, detected a pulse signal out in the indian ocean with the frequency of 37.5 kilohertz. we confirmed that is the standard beacon frequency. as they search for malaysia airline flight 370, it is possible they may have found the pinging from the blacks box. that is not confirmed or coming from the australia joint collaboration center. we are getting word the collaboration center did know about the pinging or this report from the alleged pulse signal back at lunchtime. >> a few hours ago. >> several hours ago. we don't know who might be on

their way out there already and what resources they are sending to this particular area at the moment. that is latest that we know. until we have some sort of confirmation, some of the most promising information we heard on this, the irony of it, what experts believe could be the very last day, that pinger would be emitting a signal. >> the development on the search front, but the development in the investigation. our jim clancy is live in kuala lumpur. it relates to the audio recordings from air traffic control that families wanted to hear for some time. jim. >> reporter: the families wanted to hear the air traffic control recordings. they have not been allowed to do it. we have been told the families and the pilots' families and crew were not allowed to hear. we heard the friends have been listening in an attempt to

determine who said the final good night malaysian 370. we are told tonight that their findings were inconclusive. i don't know if it is the quality of the transmissions. friends have listened to it unable to discern which pilot might have been the one that said good night malaysian 370. victor. >> that is the answer to so many questions. inconclusive. that is the finding of the avenues in the investigation. jim, do we know if the friends have not heard them or were not able to determine it, do we know if they are now able to help the investigation and offer to family members? >> reporter: i would think the next step is to analyze the recordings, audio recordings of the pilot. he posted a lot of things to youtube. he did a lot of talking online.

that would be one way to analyze that voice. i'm not familiar nor an expert on audio identification. i think that would be a digital route for them perhaps to try to determine something. it is not very much to go on. all right, good night. not all right, good night. that was erroneous. good night malaysian 370. >> jim clancy, thank you, from kuala lumpur. i want to get to tom fuentes. he has been watching this since the very beginning. tom, i want your first reaction to this information from the xinhua news agency in china in perhaps a pulse signal has been found. >> good morning, christi and victor. my first reaction was extreme

skepticism because previously released information from china has proven to be false. the satellite information you mentioned earlier, they took back and said it was released by accident. this is a government-controlled news agency. it is not a free press where somebody leaked it and it went out. it is a government-controlled agency with a government-controlled report on a government-controlled ship. the fact the report doesn't mention whether or not it was disseminated to the australians and malaysians. from the beginning, i was skeptical this may be something that they will walk back later and let's just get on that site and find out. one aspect about it that is better is all the satellite technology was five days old. the debris on top of the ocean is moving. if it something sitting on the bottom pinging, it is not going anywhere. they should have a better chance to get it.

>> tom fuentes, thank you. we will continue the coverage of the breaking news. join us back here at the top of the hour at 10:00 eastern. for now, we will send it to michael smerconish who will continue the breaking news coverage there in new york. >> announcer: this is cnn breaking news. good morning. i'm michael smerconish. breaking news this morning. we have just learned from a chinese news agency that a chinese patrol ship searching for missing flight 370 heard a pulse signal in the indian ocean. if it is coming from the black box, it is just in the nick of time. we could be days or hours before the batteries die. and overnight, it was announced that a search of the hard drive belonging to the pilot revealed he had several alternate routes programmed into the simulator. it appears he researched what to do during flight emergencies. keep in mind, thesere
