Skirted, veered off course, disappeared. The device picked up two separate signals, said to be just like those emitted by a planes voice recorder. From perth australia, where the search efforts are based. So fill us in on the latest on what were learning about the detection, how long those signals last, if, in fact, those signals could be coming from those two black boxes. Yes, certainly a promising lead. No confirmation of flight 370. We know the ocean shield detected those signals over the weekend. The first one for two hours and 20 minutes. They had a lock on it for a significant amount of time. The second one, less than 15 minutes. What theyre doing now is theyre trying to reestablish contact, to see if they can get a lock on these signals again and try to box in the area where they suspect these data recorders might be. Authorities, as you know, will, theyre using words like encouraged, promising. Theyre also urging caution, as you correctly point out. What will it actually take based on all the interviews youve been doing over there, for it to confirm the signals, the missing plane, those are signals in fact from the missing planes black boxes . Sure, yes, without question, there is just a lot of work ahead. First of all, they need to get a lock on this signal again. Thats step number one. Its a pretty its a pretty daunting task, because the ocean shield towing that pinger locator, it has about 6,000 meters of tow behind it. It takes a good eight hours to do one full sweep. That includes three hours for the ocean shield to actually make a turn and turn around the other way. Of course, as we know, every minute counts here with the black box batteries in danger of running out literally at any minute. I want to play some sound from captain mark matthews. Hes leading the team that is running this pinger locator. What id like to do before i absolutely say with certainty that it is the aircraft, is one, reacquire the signal, two, deploy the underwater vehicle with the side scan sonar to map the debris field and then, three, switch out that sonar with a camera unit and take photographs of what would be the wreckage. Certainly, were jumping to conclusions here. We need to reacquire the signal to confirm it is the aircraft. Yeah, the key word here caution, wolf, thats the message we keep getting in perth. Clearly, the optimistic, cautiously optimistic, they may be on to the real deal. Teams are also investigating the signals detected earlier by a chinese ship. Thats 400 miles to the southwest. How serious are they taking those signals . There are a lot of questions about that. Obviously, its an interesting location. It also falls along that arc. The satellite data shows the plane could have could have flown on and possibly gone into the indian ocean. There are a lot of questions about the technology the chinese were using. You saw the video of that handheld hydraphone being dunked into the water. Some serious questions about whether that device could detect something so deep. Were talking about ocean nearly three miles deep in this particular area. We know the hms echo has been there doing surveillance but we havent heard of anything significant that ship has found using more advanced technology. The real focus right now is on the ocean shield and its mission to try to get a lock on those signals once again. That australian ship does have a u. S. Navy toed pinger locator, as they say, and thats a much more sophisticated device. Will, well get back ton you. Our panel of experts to get their take on whats being called the most promising lead so far it mike weiss is cnn aviation analyst, former 777 pilot for american airlines. Peter goals is analyst, former ntsb manager director and tom fuentes is our Law Enforcement analyst, former assistant director of the fbi. Leapts go around the table. Well start with you, mark. How serious is this . How optimistic would you be based on the information thats been released . Particularly since a lot of that information came from the u. S. Authorities and the navy, that i feel a lot more comfortable with it. Still, theyre hedging their bet, wanting to make sure, trying to manage expectations. 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. Its not malaysia. Its not australia. Its not china. This is the United States 7th fleet, the navy. On this leg, where theyre 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 mh370 black box because the plane had both the flight data recorder and cockpit voice recorder. Acquisition of the the two signals is encouraging but were 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 theyre cautiously optimistic based on what theyve heard at a level of 3,000 meters under sea level, thats pretty encouraging. It is encouraging. Having worked with these guys in past stretches, they dont say things casually, that they got two pinger results back is very, very positive. Separated by about 300 meters rings true for debris field. Were still weeks away. This is the best news if these are real, the real pinging coming from those two black boxes, why would that take weeks to find those black boxes . First, you have to reacquire and try age late the location of the boxes. Then youve got to drop down the remote vehicles and that is more difficult than it sounds. Its not as though theyre going to run down and hit it on the first run and they may decide to do side scanning sonar which is, again, a very tedious process of mapping the debris field. So it could be weeks away before we know. If that beacon only the batterys about to go out, were told, lets say the batterys got a few more days left. With a little luck, maybe it does. If the ping locator is within two or three miles, how difficult should it be to find that, if its 2 or 3 because thats the range of what the beeping would be detectible. The device being towed by the ship, it may be a long way behind the ship, and it doesnt have an exact way to mark that spot. They have to come back around several times and reacquire the signal. Just because youre hearing a signal, if it is a signal, doesnt mean its going to be within the next day or so. Right, they cant say drop the submarine on that spot. Theyre kind of guesstimating by the depth. They can tell how far under the surface that device is but not the exact latitudlatitude, long. If this is the real deal, that would be amazing they locate it because they werent sure they were looking in the right haystack looking for that needle. They finally found the needle hopefully rather than just the haystack, incredible. A a mazing development if pans out. The fuel consumption of the plane, the speed, it really is extraordinary if this works out, theyve done a tremendous job. It is really very impressive. Well know now in the next few hours once that ship moves around, the locator, sees if it can reacquire that signal. If that happens, theyll be in pretty good shape in finding presumably at least those two black boxes. We have a lot more to digest. This is fairly encouraging. Word of the best lead according to all authorities, not only malaysians, not only chinese, not only australians, but the United States navy now saying theyre cautiously optimistic theyre on to the real deal. Up next, well have more on flight 370, claims that the plane was evading radar on purpose. Our panel standing by to weigh in. And jeb bush sounding a bit more and more on becoming president of the United States. Well explain. Whats your function .

Were using more natural gas vehicles than ever before. The trucks are reliable, thats good for business. But they also reduce emissions, and thats good for everyone. It makes me feel very good about the future of our company. Theres new information on the route flight 370 may have tak taken. A source tells cnn the plane went around indonesian airspace and may have been purposely trying to avoid radar detection. How is this type of information why is it just coming out now a month after the plane disappeared . I think the real short answer here is, wolf, its taken us that amount of time to get that information out of a senior Government Official here. I think its pretty clear the investigators have had this information for a while. Not quite clear how long and theyve been able to draw their conclusions from it. One of those conclusions, they think whoever was controlling the aircraft was, in fact, trying to evade radar detection, wolf. So i guess the suspicion as far as malaysian officials are concerned, once again focusing directly on the pilot or the copilot in this particular investigati investigation, is that fair . Thats definitely fair. You look at, if you will, a triangle of suspicion. At the top end, the most experienced person, the captain, 18,000 flying hours in that aircraft. The first office really only just on a sixth flight in the 777. So his experience not so high. All the passengers have been ruled out. What theyre looking at is an aircraft thats taken multiple turns. Doesnt appear to be at least suffering a mechanical failure. Whoevers in control tries to avoid radar detection, at least some part of the journey, before going off into a very, very remote part of the indian ocean. Apparently, apparently, we have to say that, with apparent knowledge that there wasnt fuel enough on that course to get to land. That opens up so many questions of course, wolf. If they were trying to land some place, maybe the theory is they were trying to go to australia or some place, but theres no indication that was going on. What do indonesians say about all this, because they havent released any information that they actually picked up any radar on this malaysian airliner. Yes, theyre telling us they didnt pick up any radar information about this, about this aircraft. That does raise questions because they say their radar can reach about 200 miles. Were told the aircraft flew around the north of indonesia. You fly between bandarasha and the southern most point of the islands in dera. Thats indian territory. We know they also have good military radar in that area. It seems impossible the aircraft would not have been picked up somehow on eindonesian radar. But thats what theyre saying. A top military official went to indonesia, met with his counterpart and was told by that counterpart the plane didnt go over their airspace, wasnt picked up by their radar. So the information doesnt tie up perfectly. There are a lot of unanswered questions. But i guess what we have here is some small gaps fills in. But the most important part i guess we could take away, again, is an inference from the malaysians about the mindset of the person at the controls they think trying to avoid radar detection, whatever that means beyond that, wolf. Interesting. All right. Another fascinating development. Thanks very much, Nic Robertson in kuala lumpur. Lets bring back our panel. Mark weiss. Our cnn aviation analyst, peter goals. Former ntsb managing director tom fuentes. Can an autopilot make a maneuver like that . The autopilot has to take inputs from somewhere. When you take a look, the first turn to the southwest which went back over malaysia, which we dont understand why the malaysians never scrambled aircraft to interset that aircraft, then took a turn to the northwest, and then again to the south. All had to be done by human input. Whether it was on an fms, a flight management system, or whether it was done by changing the heading of the aircraft, and that would have been done while the airplane was on autopilot but a manual input. That turn away from the route towards beijing, it was supposed to go to beijing that turn happened a couple minutes after the last communication, good night malaysian 370 which raises a lot of suspicions. It does. The malaysians i think after just a few hours into this investigation have been focused on the cockpit. And weve all felt that this is something that needs to be looked at. Because that plane was acting under human control. The indonesians, they said they dont know anything about this, they didnt pick up any radar. Do you buy that . Thats a good question. You wonder where were the malaysians in the first place as they crossed over the peninsula of malaysia and nobody scrambled jets, nobody went looking for an aircraft intruding their airspace. Now indonesia, another country, what about their Defense Systems as it approached . Maybe the thought it went north through the water and circumvented going over land of indonesia, the one theory is they were avoiding radar but another theory is avoiding going over land where they might get shot down or going into civil airspace because of all the airports that operate all night long in that part of the world. How low would a 777 have to fly when you say flying below radar, to be not detectible. On the ground. Really . Youre flying at 5,000 feet, are you detectible . Youre on radar, absolutely. How many miles out from indonesia before you would no longer be able to detect via radar . The indonesians said their radar went out 200 miles. I honestly dont know. If they said that, they would have to go beyond the 200 mile range. When you see that unique turn, making a left turn, going around indonesia, then heading south through the indian ocean, and then beginning to make a little turn as if youre going towards australia, what do you say . You say whats going on in the cockpit, whos steering this plane . And, you know, part of it is its on primary return. So you get out past 150 miles, it gets sketchy. Its hard to see. But still that has all the hallmarks of a plane being undercontrol. All right, guys, were going to have you back shortly. A lot more to discuss. Were going to have a lot more coverage coming up on the search for flight 370. Dramatic developments. The u. S. Navy, the 7th fleet saying theyre cautiously optimistic they may be on for those two black boxes. Also, demonstrations heating up along the Russia Ukraine border. Ukraine saying russias behind those demonstrations. Russia says quit blaming us. Were going to the region. Stand by. Ed people a question, how much money do you think youll need when you retire . Then we gave each person a ribbon to show how many years that amount might last. I was trying to, like, pull it a little further. [ woman ] got me to 70 years old. Im going to have to rethink this thing. Its hard to imagine how much well need for a retirement that could last 30 years or more. So maybe we need to approach things differently, if we want to be ready for a longer retirement. If we want to be ready for a longer retirement. These days, everything is done on the internet. And tomorrow youll do even more. Thats what comcast business was built for. Slow dsl from the phone company was built for stuff like this. Switch to comcast business internet. Then add voice and tv for just 34. 90 more per month. And youll be ready for tomorrow today. Comcast business. Built for business. Well get back to the search for flight 370 in just a moment, but theres other Important News were following including ukraine. Ukraines acting president now accusing russia of stirring things up in Eastern Ukraine. Other the weekend, prorussian demonstrators took control of government buildings in several cities near the russian border. Those demonstrators have also asked russian president Vladimir Putin to send in peacekeeping troops. Moments ago, we heard this from the White House Press secretary, jay carney. If russia moves in to eastern u crane, either overtly or covertly, this would be a very serious escalation. We call on president putin and his government to cease all efforts to destabilize ukraine. And we caution against further military intervention. Lets go to russia right now. Cnns phil black is monitoring whats going on. Whats russias response to that accusation, phil . Well, wolf, theyre saying stop blaming us for all of ukraines problems. More than that, russias response is strong, but it has not been threatening. You could almost call it diplomatic. Theyre saying theyre keeping an eye on those events in Eastern Ukraine, but what theyre pushing for in that country is National Dialogue with all political parties, all the regions. They say they want to be a part of it. They think the ultimate response should be a new federalized constitution that takes powers from the Central Government in kiev, gives it to the regions, respects the russian language as a special language, and also ensures ukraines status, which means ukraine cant get cozy with nato. Ways lacking there, what really has changed, is the sort of language that russia was using consistently at the height of the ukrainian crisis, saying russia reserve, the right to use military intervention to protect russianspeaking pen ining peop part of ukraine. Theyre not saying that now, which is a significant development. From kiev, a great deal of suspicion and mistrust towards russia and any suggested solutions for this crisis that could be coming from moscow. Jay carney, the White House Press secretary, also said some of the demonstrators in Eastern Ukraine are actually being paid. Theyre not even residents of those areas. Im sure the russians are disputing th
