pages started to gel in a book. >> the book is called "the midden world." a character suffers a heart attack. he's in a coma. turns into a wolf when he wakes up. i didn't mean for there to be a lot of me in the main character. it sort of happened that way. you need something that can sustain you and stay mentally strong. for me it was writing and the quest to get published. in a moment we'll get back to the hunt for flight 370. we have some other stories we're keeping an eye on. but this is a strange one. a tiny little spider making a very big headache for mazda. the automaker mazda. because it's now recalling more than 40,000 of its vehicles saying the cause of it is these pesky spiders. they seem to love to spin their webs inside the fuel lines. and that can clog the fuel lines and potentially cause fires. it's the yellow sac spider. apparently it has a penchant for

the smell of gasoline. i can't make this stuff up. mazda had a similar problem apparently three years ago and they had to recall more than 50,000 of these cars back then to install a little spring gizmo to install a little spring gizmo that keeps the spiders out. -- captions by vitac -- www.vitac.com you're in the "cnn newsroom." i'm ashleigh banfield. for so many days on end no clues came out of the search for that missing airliner. now this weekend they may be faint, but they are absolutely clues. and searchers are chasing them down with the best gear they've got. right now a british navy ship is in the area where a chinese crew detected some electronic pulses on a frequency used by aviator -- or aviation locater beacons. despite the sound of that, our analysts say don't get too excited. these pings could still turn into nothing related to this

airliner. add to the pings that some objects were also spotted floating in the water not too terribly far from where these pulses were heard, and it definitely gets people moving. certainly it gets equipment moving towards the site. again, nothing confirmed, of course. but, again, these are clues in a sea of where there are so few. the australian official heading the multinational search mission is calling these new leads, and i will quote him, the most promising. today if you're counting is day 31 since malaysia airlines flight 370 vanished. a 777 simply vanishing. live right now in perth, australia, the headquarters of the search mission, cnn's matthew chance. joining him is david mackenzie who's live in beijing. matthew, first to you. the hms echo. the british ship is now on site. how long has it been there and do we know of any progress at

all? >> reporter: it's been there for a couple of hours now according to the british ministry of defense. we're not getting regular updates, sort of minute by minute updates on what its progress is. the expectation is in its 14-hour journey from its previous location it was getting prepared, ready to start work as soon as it reached the location where the chinese recorded these two what have been called acoustic events. they detected these pings on the same frequency that is 7.5 kilohertz used by these beacons on top of black box flight recorders and cockpit voice recorders as well. so what they're trying to do is trying to verify that. the chinese recorded the short bursts of pings, what they say they thought they were, anyway, and this ship, the hms echo, has much more sophisticated equipment on it, we believe. and it's there to verify that they are, indeed, pings potentially from a black box. so far that kind of verification has not taken place. that's why we're waiting now on

an hour by hour basis, to see what hms echo, this sophisticated ship, designed to map the bottom of the ocean floor can turn up. whether it can verify what the chinese have found. there's another location as well which i think is worth remembering about. which is the australian vessel, a sophisticated vessel called the ocean shield is investigating another acoustic i vent some 300 nautical miles away. it's also found something that it's interested in and wants to investigate further. so we're looking for updates on what its progress is as well. so two separate locations in the indian ocean where there's potentially some hope of finding something will give us a clue to the whereabouts of this missing malaysian airliner, ashleigh. >> matthew, thank you. many miles to the north of you to beijing where david mackenzie is standing by. david, look, this has been a very promising weekend in terms of developments because there have been so many days when

there have been none or few. how are the families taking all of this new news of not only the change in the path of that plane but also three different receptions of pingers? >> reporter: well, the families really are jaded. in the last few days, even a week ago, the search seemed to have reached some kind of pl plateau. now there's a new energy to the search and new evidence they might be -- at least signs they might be closer to some resolution in this. still the family members we've spoken to really want more physical evidence before they make any conclusions. take a listen. >> maybe this is a time, maybe the next couple of days, next couple months, next couple years we will find the ending. but there will be a time that it will end. >> reporter: they just want that ending. many of the family members i've

spoken to are exhausted at this point, ashleigh. just because the many days of harrowing waiting and the many false leads. so they're skeptical, i have to be honest, ashleigh. >> it's hard. so many days after the fact for them, after they've had so many leads that have turned up to be nothing. it must be just a terrible yo yo for them. david mckenzie in beijing, matthew chance in perth, thank you both. do tune into us and let us know of any developments as it is now daylight just around the corner for you in perth and daylight has just dawned in china as well. the mhs echo is designed to chart the sea floor. map it and provide realtime environmental information. more importantly for this search, the echo is equipped with highly sophisticated sound locating equipment. it could be the key to determining whether that signal heard over 36 hours ago actually came from the flight 370's black boxes. i want to bring in our panel, richard quest. cnn's aviation correspondent. tim taylor who's now joined him to the right who's a sea

operations and submersibles specialist. colonel michael kay, former uk military pilot and cnn aviation analyst. tim, you've joined the panel since the last hour. and you've brought with you a very significant prop. better known as an auv. explain how this is significant in what's happening on the other side of the world. >> actually, this is more than a prop. it is an actual auv. it just is a shallow water version. when we talk shallow water we're talking 200 meters, 650 feet. so it will actually go down on its own and it will use its side scan to map the ocean bottom. >> effectively what we're looking at now is this would be step two. they are listening with the phones, driving the phones along for lack of a better description. now that they've got just a little piece of evidence of pinging this goes in next to start looking? >> the blue fin 21, what the navy has supplied, will be doing the work. it's a much larger system with a little bit more sophisticated navigation instruments. because it has to go so deep.

this doesn't need that kind of -- that instrumentation. >> and relative to this, the blue fin 21 is how much larger? >> oh, the blue fin 21 is 21 inches in diameter. it's probably 2,500 pounds. this is 60. >> its side scan sonar -- just pointed out those two spots where you are showing the side scan sonar. >> it'll paint a picture of what's on its side. what's underneath it, it will have a gap or holiday or blank spot. >> how big of gap? >> depends how high it's flying off the bottom. but you could have a gap that the plane could possibly be in. so the big sonar systems that the blue fin 21 has will actually have to cover one and a half times. it'll have to go over the spaces it went to cover its holiday unless it has a venting system that can look down. not all systems are equipped that way. >> just quickly i want to go to you, michael kay. there are a lot of assets that are either en route or already

there. you'll have to correct me if i'm wrong. the haixun that found -- the chinese ship that's a very sophisticated ship with a lot of sophisticated technology. not necessarily what they've shown us by video. it was one that depicted these pings. also the ocean shield that is about 24 hours away. the hms echo, another ship that is now there as matthew just reported a couple hours on site. and there's also a hms tireless. the nuclear submarine. we don't exactly know where it is, do we? >> yeah. we're not really supposed to know where submarines go. they're very covert. very secretive. they do a lot of very secretive roles around the world. they can be used for siging. it's a sponge that listens to every piece of communication out there. the drones we hear about in baghdad and afghanistan and all these places in the middle east, they have a similar sort of capability in terms of the ability to listen.

they're very covert by nature. hms tireless will be in the area. i think the key to all this, ashleigh, the passive sonar. the passive sonar is the piece of technology that will detect and listen for that ping. it's not active. it's not like this. it doesn't send out energy and look at the energy coming back. it just listens. there's a number of assets he can use. i'd be putting the p-8s out there. po siden aircraft. the p-3s. i'd be dropping the passive sonar boys into the water. the -- >> the sonar boys they hold 100 phones as well. >> they sit in the water. >> and listen? >> the question i would have for tim, is there a scenario where you can have the sonar boys floating on the surface which wouldn't detect? yet the auv would? >> of course. sound is very -- very different in the water. it has layers that it can't penetrate. looking at what the chinese heard for one and a half

minutes, it's quite possible that they did get a piece of sound coming through what's called the deep sound channel. about 2,000 to 4,000 feet deep. essentially, sound can come up and be caught in that channel. they could have picked up a minute and a half of the signal and lost it. the towed pinger. that's why they're going deep. the submarine is in there because i think they can get into -- unclassified depths are 2,400 feet for these submarines. i believe they're getting into the deep sound channel. >> one quick question for richard quest. i hate to do this, but it's critical. early on in this mystery everyone asked the question about about the elts? they're supposed to be activated by salt water. we haven't talked about that in about 31 days. i'm still not sure i understand why none of them onboard, and there are several, were activated. if this thing's in water. >> and no one can give you the answer. oh, there'll be plenty of

possibilities. did they malfunction? did the plane go down intact and therefore they've not gone into order. there's all sorts of answers. it's one of the conondrums of the mystery. people can say it's too deep, whatever. they've been damaged. 1,001 possibilities. >> there's about a half dozen of them by count. >> nobody can give you a satisfactory answer. >> it leads me to my next topic. the flight, the search for this flight, is primarily under water. yet we've had no indication of that. so what about the air search? what happens now? colonel kay is going to weigh in on that next as well.

three underwater sounds are heard. the question now, are they flight 370's missing black box pingers? a british ship with advanced

sound locating equipment has just arrived in the area where a chinese ship detected those pulse signals on consecutive days. and an australian ship also investigating. it heard it as well. but something different. about 350 miles to the north. as my guests join me, the serarh to locate the source of the sounds is on. what about the search for the debris? is that all but forgotten? our panel, michael kay. as a lieutenant colonel who spent many, many hours in the air unrelated kinds of searches and investigations, et cetera, they cannot have abandoned the force they've been using for the air search and just the debris fields. >> i think it's inconceivable that we could think the black boxes would be found without finding any sort of debris field whatsoever. as i've said many times on air, there is no smoke without fire. i still stand by that. we've got some very capable air assets. the good thing about air assets, maritime surveillance craft,

they can get places quickly. the p-8 travels 500 knots. they can get places. as i was talking about previously, they've got these passive sonars as well. they can get places and they can rule places out before you then decide to launch the vessels which obviously take a lot longer to get there. >> tim taylor, at this point, as all of the investigators and the -- the organizational team based out of the perth has effectively led everybody to understand, this search is now based in the water. gear like this is now the focus of the energy of finding this missing plane. we're at day 31. the pingers may not even be pinging anymore. if they are, and that is a big if, are we -- are we good enough at this point? do we have the kind of gear yet to be able to do this before it's all up to this? and just luck? >> well, i mean, they've got a ping. frankly, they're going to have

to -- just like when they found debris on the satellites they're going to have to go the next step and investigate that ping. that means putting assets on the bottom. >> at this point does it even matter what colonel kay said about still finding the debris? it's 31 days old. where would the debris now be in relation to a flash zone, in relation to a float and sink zone if there are many other pieces? >> it may be difficult to track it back but the debris is still an important factor in this. the debris hunt should continue. >> and it's not forgotten that air france, we knew the splash zone. we knew the vicinity. it took two years using this. a bigger version, right, of this? >> oh, yeah. >> two years of diligence to find those black boxes. and we knew the splash zone. >> there's a lot of bottom. frankly, if the ping can be legitimized with the new assets on site today and tomorrow, as the days go on, let's hope the batteries last. but if they can get another signal and they can narrow it down this is the stroke of luck that everybody's been wanting for 30 days. the real search goes on. and it could take a year or more

to actually find the debris on the bottom. this is the beginning of what's going to be a long, long term. finding the ping narrows it down. it narrows it down so these guys can go do their long, tedious search. >> colonel kay, i don't know if you'll know the answer to this question. clearly as a pilot you are very attuned to things being in one piece and flying them. you're not as attuned to seeing them on the bottom of the ocean, say, ten years later. if we find one piece of debris, if we find -- whether it's a piece of the fuselage. if it's a seat. if it's any part of a broken plane, will it at least give us a piece of evidence that will rule out many of the theories? >> tim, please jump in. i think we have to go back to air france 447. i think that's a great example of the batteries on the pingers, on the gpss or the black boxes running out and the way that the black boxes were found were through finding the debris field two years later through submersibles. that then led them to where the

black boxes were. i think if we look at that as an example, it is quite conceivable that we could be here in 30 days' time with no pings. yet having enough analysis from inmarsat, from whatever the jacc are doing to pull together to get somewhere where we can go and look with these submersibles. >> if we're in the right vicinity, which brings me back to, have we crunched the numbers correctly with the math in the field? do you remember when les avent was sitting beside you not 35 minutes ago? he asked a question of martin savidge. sitting by with mitch in the flight simulator. i see you're both still here. >> this is not going to happen. i hope the water -- >> i don't think -- >> i'm sorry, ashleigh. >> you can hear me. we're going to go to break, you two. colonel kay is going to effectively repeat for any of our viewers who heard les abend, our 777 pilot ask you that question and asked you to spend 10, 15 minutes reprogramming the simulator, colonel kay is going

to explain in simple terms what it was we wanted you to do. colonel? >> hi, guys. at 12,000 feet and a max operating speed how far could this aircraft have flown? >> that is going to be the question we ask you when we get back after the break. are we even in the right vicinity of a splash zone? that's coming up next. peace of mind is important when you're running a successful business. so we provide it services you can rely on. with centurylink as your trusted it partner, you'll experience reliable uptime for the network and services you depend on.

so right before the break, we told you we were going to go

to mitch cosado and marty savidge in the flight simulator to come up with a program whereby we would figure out the fuel burn and the length of distance that the 777 would have traveled before it would actually effectively create a splash zone and if we're even in the right vicinity. i'm switching gears. we reprogrammed something a little bit different. in fact, the reprogramming gentlemen i think you were able to do in the time for this moment was the soft water landing. the reason i wanted to ask you about this as well was because there have been a lot of people who've been curious about why the eperbs did not go off when they hit water. why we found no debris if perhaps that plane landed intact. i'm going to turn it over to the pilot who speaks far more eloquently than i do about this to ask the appropriate question to what to program for the soft water landing. colonel kay. >> hi, hitch and marty. michael again. how are you doing? >> good. we're in the dark. we had to do that to give you any sense of visualization at night which is almost nil.

>> what i just really would love to get a sense of is, as mitch is going through this, if he could just talk us through just how difficult it is to enter the glide. obviously when the engines flame out, run out of fuel, what he's doing when he's entering the glide. what speed he's coming back to for maximum glide efficiency. just the talk down of altitude. how quick it is. as he's flaring to get on to the ocean, all those sort of type of sound bites would be really useful just to give the viewers a sense of how difficult this really is. >> you want me to kill the fuel? or are you going to just try it straight? >> no. i'll fly it -- so -- so -- i'm sorry. i don't know the name. i'll answer the question. coming down, i'm about 50 feet over the water here at night. i mean, i'm -- my mind is on the flying, of course. but the idea is for a ditching at night you want to turn the landing lights off. they kind of mess with your perception. they're canted downwards. you want to get a more directional light with the landing light. you want to have a hatch open.

even in the small airplanes we open a door so you have an escape. in a big airplane like this you have a hatch. we want to have that open. of course, the back would be prepared and would be briefed. you want to touch down tail low. very low speed. vso plus ten. something like that. flap configuration maybe 15 degrees. optimum so that drag doesn't override the lift. not full flap. maybe halfway. get optimum lift. you want to touch down tail low. you're probably going to have two impacts. very violent. the airplane is probably going to hit the water, bounce and then hit again and settle in. >> things we can't take into account are sea state. we don't know winds and other weather that might have been at that particular time. so -- and because of the fact, of course, we're dealing with a sky that might have had clouds and might have only had starlight, it could without the elimination of the aircraft be almost complete. >> can you give us a sense as

well, if the aircraft does make a successful landing, what sort of flotation devices does the aircraft have, indeed, to try and make it float? obviously if this was a mechanical failure of some sort they would be deployed, i'm assuming? >> yeah. it has. you have your lifts which actually are tethered to the aircraft. they can be deployed. and you can -- you can stay with the aircraft or you can cut them loose if need be. everybody has a life jacket. you don't deploy the life jacket before you get out of the aircraft, obviously. they tell you that before you depart. aircraft that have a -- a tail canted at a higher degree angle have a tendency to sink, actually. there's a greater likelihood the aircraft isn't going to stay up aloft or stay afloat. this airplane, the 777, the tail is relatively in line with the

rest of the fuselage which bodes well for a water landing. so there's a lot of things to consider with the water landing. too much to talk about 50 feet over the water at night. >> now, mitch, i mean, you made it quite clear you're actually doing a powered all landing here. i think in the real scenario it would likely to be the two engines have flamed out because it's run out of fuel potentially. how would that differ making the glide approach versus the approach you just described with power. >> i tell you what, if it was me flying the airplane i'm going to be looking at the fuel gauges. i don't know what these pilots were doing. i'd be looking at the fuel gauges. if i saw the fuel dropping to a level below which i couldn't make a successful landing at an airport, i would be doing a powered approach. because i know i'm not going into an airport now. i have to ditch. when you have power, engine power, i'm talking about, you have a lot more options. you can control your rate of descent. for a water landing you don't want to be deskrending more than 200 feet a minute especially at night when you don't have a

reference. calm seas, glassy water, anything like that you're going to have a very difficult time judging depth. 200 feet per minute on the rate of descent on the vert kl speed. in the middle of the ocean if you don't have an altimeter setting you don't have a frame of reference. you only have your bsi. i forget what your question was. >> mitch, i think you just made a brilliant point which is if the pilots were in control, they'd never let the situation happen where they'd actually run out of fuel. they'd realize they had no other option and they'd make a powered approach on to the ocean. i think that's a brilliant point you just made. >> i'm going to add one extra question to that, mitch. that's this. with our brand-new map we received today that shows a very curious route, skirting the northern part of indonesia and then arcing back around southward and flying on for several hours southward to the south indian ocean, is there any circumstance that you can imagine where there would be two pilots who are still in any kind of control of that plane or

intending for anything other than crashing that plane? would anyone be trying to land gently in the spot where that plane on our map is being shown to have gone down? >> i can't imagine a scenario where they would be -- i mean, of course, there are scenarios where you have to ditch. a bird in the engine like what happened in the hudson. but with a healthy airplane, i can't imagine you just deciding to ditch. it doesn't make any sense. there were a lot of airports in the north they could have gone to if they had an emergency that were closer. they actually spent more time going down south in the indian ocean. why? to ditch, why? you have more options up north. >> if you had an option anywhere between that turn, that first turn which was the last thing we saw, you know, actually registering with that plane, why on earth would it go to search trouble for such a remote spot to generally land the aircraft. mitch and marty, thank you. just an invaluable with that simulator and helping us to understand so many of the very,

very arcane aspects of that 777. coming up next, that very question. that strange route. up and over indonesian air space. it sure didn't look like a ghost was flying that plane. it sure didn't look like the zombie flight that so many said it could have been. what does the investigation say about that plane skirting ind nigs air spa neegs air space. it's coming up next. it's a stationery and gifts store. anything we purchase for the paper cottage goes on our ink card. so you can manage your business expenses and access them online instantly with the game changing app from ink. we didn't get into business to spend time managing receipts, that's why we have ink. we like being in business because we like being creative, we like interacting with people. so you have time to focus on the things you love. ink from chase. so you can. so, if you're what ysleeping in your is youcontact lenses, ask about the air optix® contacts so breathable they're approved for up to 30 nights of continuous wear.

want to get you up to speed with the latest on the search for flight 370. the hms echo is the latest ship to join the hunt for that elusive pulse signal that was just detected yesterday by a chinese ship. but it could already be too late. this is where the ship detected that pulse. here's the problem. the batteries in the airliner's black boxes may be gone. at best, they may have only days or even hours before they run out completely.

again, they may have been gone for days now. the ocean shield, an australian ship recorded something they're calling an acoustic event. that was quite separate than what the chinese heard. and it was quite some distance away. 300 miles or so, to be exact. there is yet this new mystery as well tonight. a senior malaysian government source is telling cnn that the aircraft steered a course up and around the tip of indonesia. very curious. it was long suspected but it is now confirmed and it effectively skirted indonesian air space. again, very curious. why would it do that? was it an effort to stay hidden? does that mean someone was flying it and intendingal along to have that very strange path? answering some questions with the black boxes would be hard. without them, nearly impossible. but investigators have little choice but to push forward at that point. cnn's jim clancy is covering that part of the investigation. he is live in kuala lumpur as he has been for the last month.

i have so many questions about everything that you've been covering up until this point. but this latest news about skirting the indonesian air space, what are the investigators saying about that? >> reporter: the investigators aren't giving their interpretation of it. this source told cnn, this was the course that was tracked on radar. that radar would be very reliable. we're not sure which country provided it. we know that the indonesian -- the malaysians were tracking it. but this gives us a little bit more coverage as it comes around thailand or indonesia might have furnished some of this data. what it indicates to us is that the pilot was trying to avoid, you know, impinging on anybody's air space. indonesia's air space. something that might prompt a response. that the plane has already flown directly over malaysia. but it was a malaysian airliner might not have prompted a response for that reason or as it would seem, nobody was really paying much attention on that

very early morning of march 8th. what it tells us, perhaps, two things. a little bit to the motive of whoever was in control of the aircraft. whether it was a pilot. whether it was somebody forcing the pilot. whether it was somebody entirely different inside the cockpit. it also tells us another thing. this data was basically produced some two weeks ago using the inmarsat handshakes with the satellite. and it matches that data pretty well. it gives us more confidence that the tracking that was given to us by inmarsat, far beyond any of this radar, is, indeed, accurate. it tells us, ashleigh, we may be searching in exactly the right space down there today. back to you. >> what's so hard, jim, is that we keep hearing that. you know, in 31 days we've had that sort of void spree. feeling as though we might be on the right track only to be

dashed moments later. i want to ask you, being in kuala lumpur, this is the location of many of the families. clearly many of the families were chinese. i asked david mckenzie how the chinese families are dealing with this. he answered that question. you're in kl. how are the malaysian families dealing with this? >> reporter: the malaysian families don't want to get their hopes up. they would like to see a resolution of this. but they're taking a wait and see attitude. most of the chinese families here, all but three, i'm told, have returned to beijing. the ones that remain say they were just trying to be patient. they were just trying to wait. they hope they don't find the plane at the bottom of the indian ocean. some of them still hold out hopes it might have landed somewhere. they say they will accept the outcome, ashleigh. >> you've done an exceptional job. i know this is your last day of a month long assignment. there are few assignments we're sent on at cnn that last that long. thank you for your work. jim clancy reporting live from kuala lumpur for us this sunday

the indian ocean in the search area is nearly three miles deep. the distance between where the possible audio contacts were heard, 350 miles. that's not even bringing in the waves and the wind and all the other objects in the water. a lot of them being garbage. i want to bring back our panel, michael kay, richard quest and tim taylor. the very first thing i want to just read out to you, and, tim, effectively this is for you. i read in the "washington post" last week a quote from david gallow who's a director of special projects at woods hole oceangraphic institute. it was such a profound statement. i have to say i did lose a little bit of heart in this whole process of finding this ship. direct quote. the ocean can do a lot of things with sound. for instance, if you know how to use thermal layers in the ocean, you can hide a nuclear submarine from some of the most powerful sonar. could you put that in

perspective when we're talking about teeny tiny microphones looking for teeny tiny black boxes. >> they create walls. sound can baounce off it and no make it through it. put a sub right above or below one of those, and they're shooting sound to find a sub they can bounce off the therm aa thermales and not see the sub. >> if the toe pinger locater is being towed behind the vessels in question, they have to be exactly in the right thermal layer in order to detect something? >> more or less. there's one layer that travels the whole ocean from 2,000 to 4,000 feet. it goes up and down. it's a deep sound channel that sound can get caught in. propagate for miles. the sound can get caught in there and not make it through. parts of it can make it through. that's why that pinger is being deployed. they're towing that pinger down into about 3,000 feet of water where they can actually get into that zone and maybe even pick up

the signal for a lot farther than it's sending out. >> richard quest, what did the chinese know that took them to the spot that they found these pings? because it wasn't in the spot that anybody was supposed to be searching that day. >> i do love your questions, ashleigh. particularly when they invariably and inevitably bring me to answer, i have no idea. and i'm not being facetious when i say that. >> and i'm not being facetious when i ask that. >> because it is a perfect question to why the chinese were there. when it's not in the zone. why they were searching in that equipment. and what equipment they may have really been using at the time of the search. and -- and i think it doesn't really matter if they find the plane. you know, the ends will justify whatever happened. but let's remember what angus houston said, ashley. he said they're getting very, very good cooperation and he's

quite happy with the level of information that is coming from the chinese. i suppose arguably he would say that. >> colonel kay, one of the things that -- that our cia analyst told us earlier today is that he's been scanning the press in china. and invariably, the chinese press is tooting a horn saying, we've done it. we've found the plane. we solved the mystery. now, i can't say to a certainty every press source is saying that. but there's a lot of crowing going on in china about this. strategically speaking military to military. is there something you see in china being able to say that and effectively say to the rest of the search brigade, off you go. see what you can do. find it. if you can't, it's not our fault. it's your fault. >> the simple answer to your question is no. i think the negative connotations of this, we need to be very careful of in terms of that -- >> you don't see this as

political? >> well, i mean it could be geopolitical. the thing which i think is disappointing is that the chinese aren't working with the international community or it appears they aren't working with the international community to provide that information in through the jacc. allow the jacc to analyze that information. then corroborate it then disseminate it as they see fit. i think what it's doing is it's potential lly diluting the credibility once again of the investigation and causing a little bit of doubt in the people's minds. . especially chief houston. i think that's where the problem lies. geopolitically we've always had an issue with china. china is regarded as the biggest threat to america. i can see why people would be taking this tone. i think the coordination aspect is disappointing. >> tim taylor, we heard immediately upon the news breaking of these pings being located in three separate instances, two of them from the chinese, one from a separate location 300 miles away from the

australians that all of the assets or at least a great bulk of the assets were streaming towards that location to start their very hard work. what happens to all the other search areas now? >> they go on hold. they don't go away. all right? so they go on hold. and they work with the most pertinent and the most precious of those -- those zones right now. that's going to be the ping from the chinese. now, that deep zone i talked about a second ago, that tpl could have been picking up the same signal 300 miles away. quite possible in that deep zone. because they're towing down deep. where the chinese picked it up with whatever gear, as richard said, we don't know what gear they're using. they're showing us pictures of a couple guys hang a hydrophone off the water. i pretty much guarantee that's not what they're using. >> those were divers. hand held devices. the guy who actually makes it said i don't think that was it. >> they're holding their cards close on their gear. >> what? the chinese? >> i'm sure they are. >> holding their cards close? go figure. tim, thank you. michael, richard, thank you as well. coming up, you're going to hear

despite glimmers of hope in the search effort, there's

really not much comfort for the families that all of those people who were onboard flight 370 and have ostensibly just vanished. for one family it's come close to home. their home. more from perth, australia. >> reporter: these are precious moments of piece for danica w k wee weeks. she's had few of them. she's haunted, she says, by this aviation mystery and the mission to try and solve it. >> this area that we lay on now, if it's there, are they going to find it? it's a big question everybody's got. is it the right area? it's a calculated guess. so this is, i think, the hardest process for me is understanding that a commercial airline can just go black. >> reporter: danica's husband, paul, a 39-year-old mechanical

engineer, was aboard flight 370 en route to a job in mongolia when the plane disappeared. incredibly, the hub of search operations has moved just a few minutes' drive from her home near perth, australia, where she lives with their sons, lincoln and jack. >> sometimes i catch myself, you know, seeing the excitement of him coming home. and i have to -- i have to get rid of that out of my brain quickly. because i can't let myself go to that level of excitement because it would only -- it's only going to make me crash further when i find out the real truth. which we're all expecting will be that the plane has crashed. but until that point, till i have something concrete, i can't grieve. >> reporter: how important is it that they keep looking for him? that they keep this going? >> hugely important. hugely important. as i said, we need something. the families need something. we need answers.

not just for me, but for my children. >> reporter: have you started to think about the possibility that paul's sons will grow up, your sons will grow up and not know what happened to him? >> i've thought -- i've thought of that possibility, yes. am i willing to accept it right now? no, i'm not at that point. because if -- if this was me on that plane, paulie would be fighting. going everywhere asking every question, chasing down to find out what happened to me. for our sons and for himself. so i just have to do my utmost right now and keep going to find the truth. this will all encompass me, completely. >> reporter: and weeks says it's now a measure of comfort to know she's so close to the search and

that the last moments of her husband's life could have been so close to his home, so close to the people who love him. paula newton, cnn, near perth, australia. >> our thanks to paula newton. i'm ashleigh banfield. thanks so much for being with us this hour. cnn's "newsroom" continues with don lemon right after this don lemon right after this break. -- captions by vitac -- www.vitac.com guy. okay, does it bother anybody else that the mime is talking? frrreeeeaky!
