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 casually, that they got two pinger results back is very, very positive. separated by about 300 meters ri

the seventh fleet -- u.s. navy seventh fleet, operating the bluefin 21 on board the "ocean shield," putting out a press statement saying that weather is a factor. it's not in the water yet. important to note that that six hours involves some two hours of the bluefin 21 actually getting down to the ocean surface. it had two hours to search and two hours coming up. it was only searching the surface of the ocean for two hours. the data collected, the seventh fleet releasing the statement saying no new objects of interest found. officials here in australia have said all along that this is likely to be a slow and stain staking process. -- painstaking process. that seems to be the case. in terms of what happened, the bluefin had ascended for its search and came cross the outer reaches of the area when it came across waters deeper than the 4.5 kilometers it was programmed to be able to deal with, 4.5 kilometers being the edges of its search capability. resurfaced. we understand they are reassessing that search area, perha

u.s. navy's seventh fleet. good to have you on commander, saturday's search was the smallest, most refined one we found. do you know what this is based on, how they're narrowing it down? >> well, yeah, if you look at the four different detection areas they are really only between four and ten kilometers apart. so it is not that bad of an area, you know, certainly considering where we started from. but the critical point is, every even -- you know, couple feet that we can shrink this down is very critical for the bluefin-21 sonar. as slow as the tpl goes, for the tpl, we have to tow it behind us about at the pace a person walks. well, the bluefin is much slower than even that. so imagine you're walking down the sidewalk and instead of just continuously walking, you have to walk and take a picture. and you do that every so often. so even if you cover a couple of square miles it might take a day or two with the bluefin. so that is why we have to stick with the tpl for just a little while longer to make sure we hav

u.s. navy's seventh fleet which is taking part in this search. >> commander marks, we've been told to expecte kind of big operational news conference some point. do you have any information about this? have there been any developments that you've heard of? any positive developments you think they might be announcing? >> hello. it's about 7:30 in the morning here in the western pacific. so looking through the information that came in through last night i do not have any significant developments. >> the hms echo we understand is now conducting a specific search, we're told. what exactly does that mean, a specific search? and why now? do they have any information that's letting them close in on a certain area? >> well, right now we are making the best judgment call we can based on the life running out of the black box. so the echo is out there. we also moved the ocean shield with cooperation with the australian government that has the tpl, the towed pinger locater and the blue scan the sonar side. so really the best thing we can do right now is put these assets in the best location, the best gu

u.s. navy 7th fleet in perth. >> as we brought the pirng along the signal got stronger and stronger and then weaker and weaker. that's exactly what you want to happen. >> search teams are trying to reacquire the acoustic signal so they can fix the location. then they would send down an underwater vehicle with sonar, help construct a map of the ocean floor and any wreckage. >> we have a promising lead but we have yet to get the confirming evidence and that will be a long process. >> reporter: now the ocean shield is operating in depths of close to 15,000 feet that's close to the maximum depth that that underwater vehicle could operate in so officials say, if the plane ended up in even deeper water, that could only complicate things. make it more difficult to salvage. charlie. >> seth, thanks. >> mark rosenker is in washington former chairman of ntsb. mark, good morning, tell us what makes this is the most promising lead. >> this is an absolute fascinating discovery, they have been able to listen to these boxes or whatever the signal is for two hours and 20 minutes, plus, again, after they mad

u.s. navy seventh fleet scrambled to assist the overturned vessel, rushing to pluck the passengers clinging to rails. these two passengers were lifted to safety in a helicopter basket, while dozens of others were pulled from the water by rescue boats. one passenger told ytn they were told to jump into the sea as the ship began to sink. within hours the ship was almost completely submerged. only a small portion of the hull was visible above the water. the weather was clear at the time and authorities are still not clear on what caused the catastrophe. >> that was pauline choiu reporting. divers have been trying to get into the search to search for survivors, but they are struggling against strong currents. we'll keep you posted. >>> right now the under water search for flight 370 once again under way. we're waiting for bluefin-21 to come back up from the sea after a technical glitch forced the submersible to resurface briefly. that would be the second setback in as many days. the submarine scouring the ocean floor as analysis from the first short earned mission this morning finds no debris.

u.s. navy 7th fleet is playing a key role in the search.ime ago, the fleet spokesman, spoke. >> it was a period of significant detection. we heard a ping at one second intervals, that was the first indication. at that time, the towed pinger locater was only about 300 meters deep. now, that is not as deep as you would expect. so, at that point, it was encouraging to get a signal, however, we were not overly optimistic. so, that was at 300 meters. at that point, the ocean shield turned off all the noise producing equipment. you want to reduce any chance of a false alarm. they did that, and then at that point, they held that signal again for over two hours. now at that point, the pcl was lowered to about 1400 meters. so that was deeper and that is more where you would expect to get the signal. the tow pinger locater, the signal should get stronger and then fade as you go past it as you go past it, and that is what it did, it got stronger and faded out. so that was encouraging news. after that, they passed the signal, what you do is you reel it

u.s. seventh fleet officer. what will the role of the u.s. navy be moving forward? >> that's a great question.ansition period right now. there are a lot of really intelligent people looking at the long term approach for what is the best way to search this expanded search area. a few things we have to look at. first is as the prime minister said, you know, we believe the value of these flights is diminishing. most of any debris that would have been on the surface most likely is sunk. and you have this expanded underwater search area. what was also to be searched with one side-scan sonar, the bluefin in a couple of weeks you expand that to this 400 by 50 mile or so box and that is much greater or much more than one side-scan sonar can search. so the factors you to the look at what assets can you bring in and where do you place them? there are a lot of commercial solutions out there. there are a number of side-scan sonar. you have to look at the depth of the area whether you want to tow them or if they are remotely operated. a lot of variables in place. but this week is when those discussions are

u.s. navy welcomed the latest addition to ith fleet, a stath destroyer, the first of its kind. uss "zumwalt" was cystened in main. the 610 foot ship is the largest destroyer. thanks to its advanced technology the ship requires half the crew of existing destroys, and the uss "zumwalt" is scheduled to go into service in 2016, and cost over $3 billion to build. in other details about the zum r the commanding -- uss "zumwalt," the commanding officer is captain james kirk as the first leader. that's right this captain kirk is the real deal, a graduate of the naval academy of anapolis, with 25 years of experience. seems like more than a copies dense that his name is captain kirk and he commands the futuristic ship. >> he probably does spoken word poetry, and i bet everyone listens. >> we will, that's the truth. >> folks are listening, especially to weather reports in iowa now. we have been getting powerful thunder storms coming through, bringing up hail storms up to a golf ball size. some compared them to a half dollar size. we had wind gusts up to 60 miles per hour. storms are start

u.s. seventh fleet, which is, of course, the part of the u.s. navy that lent the very sophisticated monitoring quimonitor ing equipment to the ship that detected these pings, that so far they haven't managed to reacquire those pings. they can't find them anymore. they monitored them for 2 hours on one occasion and 13 minutes on another occasion, but that was a day or so ago, and there haven't been able to find them again. we'll get some more clarity we hope in the coming hours. >> and richard, we shouldn't downplay that. when we hear angus houston will show up at a press conference, he's been bringing us really good information. >> it's his opportunity to bring us up to date, the australians will say thank you for what's been going on, but we need to know the latest information on the pingers. >> stand by, that should happen at the top of the next hour, 11:00 p.m. eastern. joe, it's been an agonizing month in limbo for the families. how are they reacting to the news of these new signals? >> reporter: it's been very hard to trust,ic we can say, and th

u.s. navy ship to the black sea where the russian naval fleet is based, and it is expected to arrive thereithin a week. the pentagon says the action is being taken to "reassure partners in the region." is that reassurance i hint of military intervention? >> we are still in the realm of gestures, so yes, you can send a warship into the black sea. that will cause some consternation between the turks and the russians if the u.s. tries to overstay its welcome in the black sea. still, the u.s. and nato are not prepared to engage in actual military action against the russians. it will certainly see an uptick in military exercises and rotations and talk of defense deals to countries on the eastern front with russia. but still, this is avoiding a confrontation. >> how vital a security asset is ukraine? >> it depends on who you are talking about. russians it is a vital national security interest. for the americans, ukraine is a tool to keep russia in check while it enjoys disproportionate power on the continent. russia is going to be playing the long game in ukraine. in that this is a government th

. >>> joining me now on the phone, navy commander william marks of the u.s. seventh fleet, he's onboard the u.s.s. blue ridge, leading the search for flight 370. thanks for taking the time. at this point, you haven't reconfirmed the pings from the flight data recorder or cockpit voice recorder, right? >> that's correct. we have not yet been able to reacquire this signal, and as encouraged we were about two days ago when we first got the detection, as the hours pass, we are -- our optimism is fading away ever so slightly. the important point to note about our toad pinger locator is, it is only effective when there actually is a sound coming from the black box, so it is a passive hydrophone system that listens for sound, so every minute that goes by is another minute where the battery life of that black box dies down, and without a signal coming from that black box, the pinger locator won't be effective, so we were encouraged when we initially had this detection. it was a solid two hours' time, then we turned around on a reciprocal course and got another almost 50 minutes, a

joining me now on the phone, navy commander william marks of the u.s. 7th fleet onboard the u.s.s.lue ridge. commander marks, good morning to you. as of now, american planes still flying over the search area. how much longer is the united states going to be involved here? >> that's right, we still are flying over the search area, and, of course, we still have the bluefin under water still searching. it is an important juncture right now. we're in the transition period, and i'll call that the transition from the tactical precision search to a more long-term search, and i say tactical precision search, and that's around that circle with the radius of about ten nautical miles. that was really focused on the area where the t.p.l. had that really long period of detection about two hours of detection a few weeks ago. so i call that a precision search, because we had our one asset, our best asset, in the water, the bluefin-21 side scan sonar. made the decision to search this area based on the t.p.l. detection of the pings, and we didn't find anything. but that's okay. now we're at this ju

he's the smokesman for the navy's seventh fleet which is overseeing the u.s. role in the search. you just got out of a briefing on the search. any new information to share with us? >> well, pretty much we are still in this continuous 24 hour search to reacquire those initial pings we saw and now it's approaching 72 hours. so it's between two and three days ago. so, we were cautiously optimistic as each minute passes that phase as the battery life of these black boxes fades. so, there were some reasons and still some reasons to be encouraged. one, we did have two plus hours of detection time and that certainly is significant, and i should also say it was on two courses. so two hours on one course, then we reeled in the ctl, turned around on a reciprocal course and had almost another 15 minutes. so that was very encouraging. the second thing that was encouraging is that as we -- as the ocean shield moves through the water, as we approach what we thought could be the black boxes the signal got stronger and stronger and as you pass it it gets weaker and weaker. that's consistent with

u.s. navy and asked, why the bluefine-21. they said, when searchers asked the u.s. government for help, they looked at the fleet one deep water that was available and sent out the bluefin-21. we pent on a search for an auv to go deeper than the bluefin-21 and here it is. this world war ii 2 era plane crashed off the coast of massachusetts in 1947. for more than 50 years, it remained lost on the bottom of the ocean. over a decade ago, an auv, aon the mouse underwater vehicle discovered the missing plane. >> coming up. having the right tool is always the best case that you're looking for. >> reporter: high droid make it is remus family of auv. this is a larger auv and found air france flight 447 in 2011. mike mall radiony was on that mission. >> at the end of the day we knew what we were doing is to try to help people answer questions about that flight. >> reporter: if the bluefin-21 currently being used in the search for malaysia flight 370 can't find the missing jet searchers could call upon the remus 6000 and navigate in waters almost 5,000 feet deeper than the bluefin-21. >> basically operated in most of the

fleet and you're going to finish us off with one final operations for, but the u.s. had elazig capable fleet but decisively defeated the larger japanese fleet because the navy had broken the law and was reading the japanese codes. the american fleet won that battle because of that advantage and save the united states. they have lost that battle we would have had to a reach an agreement or trees with japan as much on their terms as ours, but we did not have to. so the communications, everybody uses it. that is the challenge command we have to be able to manage and control that. communication is changing. the enemy now knows how we do it therefore, they are changing their way of communications. it will make it ever more difficult. as the biggest challenge we have, because of the loss of that important technology. what does the future of intelligence look like? in light of the recent communications rather than recent criticism from congress -- from the congress? well, it does not look too good. it turns out they're claiming that the cia has been monitoring the congressional traffic. the cra has responded. at that -- i fear what happened if we don't allow. i don't believe

fleet. they were going to finish us off if one final operation of the battle of midway. but the u.s. had a lesser capable fleet, but they defeated the larger japanese fleet because the navy had broken the law and was reading the japanese code so the american fleet because of that advantage won that battle but essentially i think saved the united states. if they had lost that battle we would have had to reach an agreement or truce with japan as much on their terms as ours but we didn't have to do it. so the communications everybody uses that is the challenge and we have to be able to manage the controls that. communications is changing and the enemy now knows thanks to mr. snowden how we are doing it. it's ever going to be difficult and that is the biggest challenge we have is because of the loss of that important technology. >> what does the future of the intelligence community look like in light of the recent communications and the recent criticism from congress lacks well it doesn't look good, doesn't? they are claiming the cia has been monitoring and i fear what would happen if we don't allow that. i don't belief for a minute that they were tapping the congressional c

u.s. navy ship caesar chavez is on its way to participate in the five-week long search. renee marsh, cnn, washington. >> the ship that renee mentioned is part of the navy's seventh fleet. that is also the fleet that is operating the pinger locater, the one that detected possible signal locations in the ocean four times already. so let's go to commander william marks who joins us on the phone. the spokesperson for the seventh fleet. commander marks, i have to ask you have any new signals been discovered in the last few hours? >> not in the last few hours, it is 10:00 in the morning here, i got the information on the potential hit for the australian p-3. i'll let them announce that, i don't want to steal their thunder, but they have a few tricks up their sleeve. if that was the case, they will report on that one. i just got out of the morning brief, the last few hours, we're analyzing the fifth pinger hit. and remember this is a continuous 24-hour operation. so in essence we never stop looking. it is completely around the clock. >> and commander, did this fifth potential ping factor into the decision for the search area yet again today? >> well, i do need to let the aust

team heard fleeting pings on friday and saturday, but they were using some gear that is not particularly designed for deep ocean searches. the australians, however, are using gear from the u.s. navy, particularly designed for the kind of search that we're in at this point. twice yesterday and once more for two hours and then later for 13 minutes was what they were able to detect. importantly, the second batch consisted of two distinct pings. that's something you might expect from two pingers. don't forget, there's one each on the flight data and cockpit voice recorders. and still another day of eyeball scans on the ocean surface turning up no signs of any kind of aircraft debris. the australian search leader is admitting while the pings are a promising lead, and i'm going to quote him, we have to get confirming evidence. back in malaysia, the authorities are confirming flight 370 was never picked up by radar in neighboring indonesia. and as you can see on that map, the source telling cnn the plane flew around indonesian airspace before finally heading south. making a very curious northern arc. so what's next? tops on the wish list for the u.s. navy captain in charge of the ping l
