u.s. navyilarly saying it's cautiously optimistic that they may have located those two black boxes. matthew, thank you. american military, proving to be crucial for the underwater search for the plane. let's go to our pentagon correspondent barbara starr. how confident is the navy this, in fact, could be pingers coming from those two black boxes? >> well, wolf, as we have been saying, optimistic, encouraged, but nothing definitive yet. crucially, that's what the technology must demonstrate. something definitive. what we are talking about, wolf, and we've shown pictures of it for several days now. this pinger locator device you see in the water, think of it this way. it's like mowing grass. it's going to go back and forth. back and forth. until it can begin to narrow down the area where it is hearing the sound. that is what's going to get it down to that, what matt withdrew w you was talking about, that three mile by three mile box. once they can do that, once they get that pinger sound isolated

when the u.s. navy are cautiously optimistic, they are not just making that up. >> oh, this is in a different league, wolf. from having no idea at all to then culminating together a theory based on some sort of unproven and untried science of satellites, refining it, changing the search area to the point where they have said we pretty much these are the pings all but dotting the i's and crossing the t's for verification, this is historical. the fact that they have managed to do this at the very edges of frontiers of the technology. so i would go -- i think last night angus houston was being suitably restrained but even he couldn't avoid using optimistic, very promising, best lead. and the facts themselves tell their own story, wolf. >> have you -- are you surprised, van, if in fact that pings were coming from these two black boxes that they managed to locate this area without any wreckage discovered whatsoever? >> i guess the best analogy right now, since we are into march madness, this is the buzzer be

the u.s. navy has this whole thing posted on their website as a way of essentially saying this is a joke radio transmission.

the u.s. navy did put out a statement, peter, the 7th fleet, in which they said -- let me read to you a part of that statement. the bottom line, this is the united states navy. it's not malaysia. it's not australia. it's not china. this is the united states 7th fleet, the navy. on this leg, where they're investigating right now, the pinger, the locator, the tpl, detected two signals at the same frequency but in different locations. this would be consistent with the mh-370 black box because the plane had both the flight data recorder and cockpit voice recorder. acquisition of the the two signals is encouraging but we're cautiously optimistic pending confirmation of the black boxes and visual confirmation with the sonar. when the u.s. navy puts out a statement like that, that they're cautiously optimistic based on what they've heard at a level of 3,000 meters under sea level, that's pretty encouraging. >> it is encouraging. having worked with these guys in past stretches, they don't say things casual

australian officials say u.s. navynt attached to an australian ship in the indian ocean has picked up two separate underwater signals consistent with black box pings. >> this would be consistent with transmissions from both the flight data recorder and the cockpit voice recorder. >> reporter: australia's "ocean shield" carrying sophisticated listening technology listened to one transmission for about 2 1/2 hours and another on its return trip to the same area for about 13 minutes. >> probably in the search so far, it's probably the best information we've had. >> but officials say it could take days to determine if the signals are actually from flight 370. >> in very deep oceanic water, nothing happens fast. >> hundreds of miles away a british navy ship, request "hms echo" searched where a cry sneeze crew heard signals friday and saturday. the new clues come amid analysis of the flight's path. officials say they determined that flight 370 flew around the indonesian airspace on its way to the ocean which may have been a

you heard it here on cnn, the u.s. navy is sending a supply ship to replenish other ships so they don't have to break away from the hunt. this, after a possible signal which could be from the plane's black boxes was detected for a fifth time in the ware. they are trying to narrow down the search area significantly. at times in this mystery it's been hard to know what information to trust out of malaysia. sources are giving cnn new details that seem to indicate precious time may have been wasted in the international search effort. malaysian government officials, however, are taking serious exception. our joe johns has more on that and on new revelations that could explain how the plane flew so long without making even a blip on radar. >> reporter: it has been one of the lingering mysteries of flight 370, what happened in those first few hours after it went off course. why had the plane disappeared from military radar for 120 knot call miles after it made that left turn and crossed over the malay peninsula. new details about

our job as the u.s. navys to kind of take that direction from the australians and the other partner governments in the area and begin the search that we can begin. so we put our tow pinger locater in the water. we did that yesterday. it will follow a track about 100 miles or so in that area. going at a speed of 3 to 5 knot nauts listen fog that sound. that area we are looking is 84,000 square miles or so. about the size of utah. >> which is huge. 20th day. four weeks ago tonight. they say 30 days. probably get appear acouple days extra on the pinger. 30 days is what they sell it as. are we going to get 30 days out of this. >> hard to say. there is a lot of factors involved. it could be up to 40 days that's assuming the pinger is sending out a signal and at any time break on impact and it's in that area. >> if we determine that we don't think we are beyond 30 days and maybe beyond 35 days we don't think there is possible it could be any more pinging, what's the navy going to do at that point? >> again, we are

phoenix is the owner and operator of the bluefin, but the u.s. navys contracting with phoenix to deploy the bluefin, wolf. so the navy is footing some of those costs for this phase of the operation. >> you're also getting some new information on the overall costs of this search. >> that's right. an official with naval sea systems command says the u.s. navy has budgeted $3.6 million approximately for its portion of this operation. now, that covers the deployment of the bluefin. it covers the towed pi eed ping locaters deployment, that found the underwater signals more than a week ago. it covers the costs for ten operators onboard the ocean shield. that would include the nine phoenix operators plus probably one navy operator. it also covers their transportation to the region and then back to the united states. presumably also transportation for the equipment onboard the ocean shield. but, again, this is just the u.s. navy's allocation for this phase of this operation. it does not include what the australians are spending to deploy the ocean shield. >> t

the device was first tested and deployed by the u.s. navyt for this purpose. >> in anti-submarine warfare, this is one of the tools the navy has to look for and track enemy submarines. they're under the ocean's surface. they don't have a radar signature. you need to use sound and smart waves actively and passively to find them and track them. >> reporter: on this mission, the sonobuoys and planes deploying them have been modified to detect sounds in the frequency range of black box pings. sonar operators are manning computers to receive and analyze the signals. sonobuoys are dropping in a pattern, 84 at a time. they have a shorter range to detect signals than the towed pinger locator, but they're durable. >> the beauty is they stay out for up to eight hours. >> reporter: then they expire and sink to the bottom. >> while they're deployed, the sonobuoys can go about 8,000 feet down. how can they depict signals from black boxes? the sound moves through the water in a manner that can be detected further away. and with good weather, signals are a

the u.s. navy is on standby. we do have an amphibious assault ship with about 3,000 sailors and marines there in the vicinity of the area. and we're prepared to provide various kinds of support as requested by the south korean government. >> and with this type of ship going down, obviously a large number unaccounted for, over 300, is it fair to speculate that those folks could be rescued or could they possibly be trapped in air pockets in that type of ship? how does that situation play itself out? >> luke, can i tell you the republic of korea, their navy and coast guard are doing great job. they arrived on the scene very quickly after the incident occurred, and they're working very tirelessly to locate all the missing passengers. and as for us, as members of the navy and, you know, we work routinely in this area. as you know, you probably know, we operate routinely around the republic of korea, many times with our partners, the republic of korean navy. we have practiced many times and are standing by, ready to as

u.s. navy using advanced technology desperately trying to keep alive their most promising lead yet the man who speaks for turs effort joins us fresh from his latest briefing. also the batteries in these pingers are only supposed to last 30 days. we of course are at day 32. are those pings really from flight 370's black boxes or are they from something else entirely? and, two weeks after airline officials told families that all lives on 370 were lost, the face of the malaysia jan investigation said miracles do happen. are the malaysians fostering a sense of false hope? good evening everyone i'm jake tapper. welcome to this special primetime edition of the lead. there are no time-outs left as we speak, a u.s. team aboard an australian ship operating the key tool in the search for flight 370 is working around the clock to follow what's been called the most promising lead yet but they do not have much time before that promise will fail. the australians have narrowed the search to one instead of sev

the u.s. navyo produce a three dmenal map of the sea floor. each mission takes 24 hours to complete. so searching the entire area could take as long as two months. with the bluefin in, the towed pinger located is out because no pings have been detected in six days. authorities say only one device can search under water at a time. >>> also today authorities announced that an oil slick has been spotted in the search zone but the source has not been determined and a sample will be tested. so many questions for cnn's safety analyst, author of the book why planes crash. good to have you with us. i have so many questions. i hardly know where to start. you and i were chatting off camera. we heard angus houston from australia urging caution and saying, it's going to take some time. you're optimistic. >> i am because i can be. he's not in a position where he can. he's been very good about this. i've been saying before about accident investigations. the key to a good investigation is not to draw conclusions

tops on the wish list for the u.s. navy captain in charge of the ping locator is to reacquire those signals that were so promising again and again, until the source can be nailed down. that officer spoke with my cnn colleague will ripley. >> if this really is the missing plane and that's still a big if, how could you even begin to describe such a discovery? >> it certainly would be a miracle if this does turn out to be the aircraft location. >> "miracle," a strong word with an even stronger warning from u.s. navy captain mark matthews. >> i caution not to be overly optimistic here. we've got some work to do before we can say that we have a true contact here. >> matthew's team is on the ocean shield using a pinger locator listening for pings from the black boxes. over the weekend, they heard two promising signals in the southern indian ocean, one of them held for more than two hours. >> what i'd like to do before i absolutely say with certainty that it is the aircraft is, one, reacquire the signal. two, deploy the autonomous

wants to see. >> so a good move by moving this u.s. navythe black sea or will that even matter? >> well, i think the u.s. is trying to do two things here. first and foremost, deter president putin from going into the eastern ukraine. and the only device is the threat of economic sanctions from the u.s. and you're rap. this other move of positioning a u.s. warship in the black sea in international waters, that was also done by president bush this 2008 when russia invaded georgia. it's largely symbolic and second objective that the u.s. has and that is to reassure the nato allies, in this case bulgaria, romania, that the united states will protect the nato allies. ukraine is not a nato ally, but bulgaria, row maniamania, furth nos, poll north, poland, all those allies are worried whether you putin will go further. so president obama's test is to let putin know that nato is s g sacrosan sacrosanct. i don't think it will come to that. president putin is highly rational. he does respect power and strength. that is in nato. but will he respect th

so the u.s. navy sent the ship there for reassurance. the russians on saturday have two su-24s in the air. one of them passing by "the donald cook" 12 times over a 90-minute period coming as close as 500 feet in altitude as it passed by 1,000 feet off the side. so if you can envision this, the russians were not about to, you know, cause a crash or anything like that a thousand feet off the side of the ship, 500 feet above the ocean surface. what they were up to was harassment and they got the "donald cook's" attention. we're told that the ship's captain, the ship's crew tried to call the russian fighter several times to tell them to back off. they got no response. and about after 90 minutes, the russians broke contact and flew away. but the pentagon saying this is provocative, unprofessional and certainly worried because these types of close encounters still, despite any intentions, they can go very wrong. pamela? >> and the plane appeared to be unarmed, is that right? >> that's a good point, yes, it did appear -- it did not appear to ha

the u.s. navy today in the center of the new search area, their goal is to reacquire and zero in on the sounds they picked up sunday. one ping heard for two hours. then two pings heard. when ocean shield towed the locator back at a depth of 1.9 miles. >> significantly this would be consistent with transmissions from both the flight data recorder and the cockpit voice recorder. >> reporter: data in the boxes will last years but the pinger batteries will soon die making finding the recorders much harder. after malaysian flight 370 disappeared, plan a was to find the black boxes and solve the mystery by first finding debris. then the crash site. but the airborne search has failed. this is plan b, a long shot. >> if we luck out, it will be the first time in history that we've been able to go without debris and low locate the black boxes. >> reporter: cameras set to go down maybe three miles to look for the boxes. another drone later would rip open wreckage and get the recorders. >> i think at best if t

pings from the flight recorders can help to refine the search area so crews can send a small u.s. navy submersible 14,000 feet down to map the ocean floor. >> hopefully in a matter of days we will be able to find something on the bottom that might confirm that this is the last resting place of mh-370. >> investigators have not said how long they will wait to deploy the sub once they've determined they've heard the last ping. officials will only say that time is not far away. now, the new signals are being called weaker and briefer than those heard over the weekend, which could mean the batteries are dying but could also mean that the flight recorders are sinking or the locater could simply be farther away. anne-marie. >> all right. susan mcginnis in washington. thank you, susan. >>> oscar pistorius is back on the witness stand at his murder trial in south africa this morning. the olympic star known as blade runner is testifying about the death of his girlfriend reeva steenkamp in 2013. yesterday pistorius cried as he described the moment when he realized he shot her. >> i sat over reev

they can reacquire it and that's what they're trying to do, using the u.s. navy's code ping locator dragged behind an australia vessel, if they can reacquire it, that will help them better establish where it's coming from. once they have done that, the next stage will be to launch an underwater vehicle which is being carried aboard that ship. the purpose of that vehicle will be to scan the ocean floor, initially using sonar but potentially then using cameras, looking for the black box, looking for wreckage. now the challenge they face, and this is one of the reasons why today the search coordinator was so cautious is that the water there is 2.8 miles deep and that is roughly the limits of the operation of that -- of the underwater vehicle they're carrying. so it may entail them taking out other submersibles. at the same time, the battery life on the black box is beginning to run out. they talk about it being for 30 days. we don't know how much more life there is in the black boxes. so certainly there are still challenges as they try and reacquire that signal, franc

the problem is the navy, the u.s. navyut they say all three are on military missions. they're tasked to do other things. the navy won't tell us anything more. we get the sense maybe it's classified. they say basically those are not available. now, what phoenix international has just told us is they're considering now tweaking the bluefin that's out there to be able to go 5,000 meters deep. that's 16,400 feet. a little bit more than 1,500 more than it can go now and about 3.1 miles down. this vehicle out there now in the indian ocean, they can tweak it to go a little deeper. they're thinking about doing that now. >> brian todd, thank you. >>> ukraine's government seems to be losing control in several eastern ukrainian towns. pro-russian separatists are taking over military vehicles, they're planting russian flags on them. should the u.s. be worried? what can the u.s. do, if anything? our military analyst stand , by. >>> in ukraine, tensions are high right now. pro-russian militants and the army are facing off in towns in th

the australian ship that is towing that u.s. navy ping locator is going to keep trying for the next several days. but now that we are past the 30-day mark, time is running out for the batteries inside the flight data recorders if time hasn't run out already. >> reporter: australia's ocean shield equipped with a high-tech u.s. listening device is searching deep in the southern indian ocean, trying to relocate pings that could be from flight 370's data recorders. >> the towed locator pinger work continues. there have been no further contacts with any transmission, and we need to continue that for several days. >> reporter: the signals, one lasting more than two hours, the other, 13 minutes, were first picked up over the weekend off the coast of australia. if crews can narrow the search zone, an unmanned underwater vehicle is ready to map the ocean floor for debris. >> we will not deploy it unless we get another transmission. >> reporter: batteries in the data recorders have likely reached the end of their 30-day expected life. but inve

captain matthews of the u.s. navy says he believes the pingers are still alive at this point even though the ship has gone back and can't find the signal it picked up a few days ago. how long can the search realistically go on with the expectation that the batteries will be found and heard? >> he said 15 days which to me seemed rather excessive, frankly. they have a vehicle on board that very ship, on board the ocean shield. an unmanned vehicle that can go down and start painting the ocean floor with sonar. and i suspect there will be pressure to deploy that sooner. my experience with lithium batteries, they tend to quit rather quickly. what an amazing stroke of luck that we caught the last of the pings, maybe that happened within five days. there is going to be a lot of pressure to deploy that unmanned vehicle. >> david, why are we still on 30 days for black box batteries, why don't they last longer? >> that is the biggest disappointment. we shouldn't have that deadline at all. five days is replaced for the french au

>>> tonight, the u.s. navy is agreeing the signals in the water are almost certainly from black boxes from flight 370. i'm jake tapper, and this is "the lead." the navy lead, echoing the world saying they are very confident they have found evidence of the black boxes. time and again, malaysian officials have fumbled in their investigation. and the airline in question even lost black box data before. so if the recorders are found should somebody else maybe take a crack at what is in them? >>> and directing the top grossing movies of all time. he is also an under-sea adventurer with the coolest toys at his fingers. we asked if he would put any of them in the search for flight 370. good evening, everyone, i'm jake tapper, welcome to "the lead" and it is a special prime time edition. in our world lead tonight another positive sign in the search for flight 370. officials again are tightening the search area off australia's coast, about 2,000 square miles smaller than yesterday. in fact, this is the fifth consecutive
