Is technically possible that they did, because of the ocean liars, the gradient, the temperatures, its technically possible they picked up the same ping from the black boxes, if thats what they turn out to be. indeed, yes, the answer is yes. >> mike, i imagine theres a lot of noise in the ocean. what other, if any other, natural sounds, could be confused for the pinger? >> weve talked about this throughout the day. we cant really identify a sound that would be misconstrued as this pinger sound. ...

Put sonar assets into the water. >> so thomas, 133 searches so far. all of them fruitless to date. should we still hope? >> absolutely. i mean, you look at the problem. its a very, very hard problem. but right now, there is a lot of information that has come from the inmarsat data that was analyzed. there is some narrowed area of the search that the team feels is highly probable from how theyre describing it. you dont stop. there is no reason to. but there is no -- you really have to understand ...

Credible to me because of the equipment they were using and highly possible they were doing some testing on the pinger. i didnt give that a lot of credibility. now we got it from this machine from that pinger locator im very confident. >> david, even though the frequency that they heard was slightly different than the normal frequency for these? >> well, yeah. remember that there are 37.5, but even at manufactured they have a tolerance level of one frequency, one kilohertz. so, we got that to th...

Do? >> because they were focused on hearing the pings again, they have to have quiet and they have the towed pinger locator. they put that in the water, go slowly and its quiet and they dont want the submersibles down there stirring up thing moving around when theyre listening for the pings. as soon as they had a chance to have battery life and zero it in with that, that was the number one priority. now if the pinger truly is gone, the battery is dead, thats it. theyll move on to that. they had ...

Be it, because the frequency is about the same. am i right? >> well, you know, i guess it all depends on how you look at it. its not the frequency that you would expect to find. some people pointed out, theres factors that can affect the frequency that the pinger puts out. and that could explain why its not the same. even though its wrong, maybe its not so wrong that it rules it out. >> how wrong is it? >> its off by about 10%. so its not wildly off. but you know, theres different pieces of equi...

Transmission, in which case well probably have a better idea of whats down there, and well go down there and have a look. [ inaudible question ] yeah. the issue is that if we can get more pinger -- well, more transmissions, we can get a better fix on the ocean floor, which will enable a much more narrowly focused visual search for wreckage. thats the issue. if we go down there now and do the visual search, it will take many, many, many days. because its very slow, very painstaking work to scour ...

Water search and rescue expert. also back with me, mr. richard quest. im excited to talk to you about this, mr. mirs. lets assume that the pings that, you know, have been picked up and towed with this pinger locator are the black boxes. and you led the expedition that found the hmas sidney, which sunk in 1949, very near the area where the "ocean shield" detected the pings. what can you tell us about the challenges of working in those types of waters? >> well, our challenge was similar to this on...

Listen to how loud it is. there are at a minimum 15,000 ships on the oceans any given day creating even more obstacles for a search thats already daunting. let me add one more complications, and this is how sound travels in water. high-pitched sounds, oceanographers, tell me, dont travel very far, and a pinger is a high-pitched sound. so brooke, when we talk about the depths of the indian ocean, and in this case were talking about two to three miles deep and the range of this pinger is two to th...

Shallow water. but they are designed to function in water as deep as 20,000 feet. but what about the frequency? crews at sea picked up a slightly lower frequency than the pingers stt frequency of 37.kilo hertz. they said water temperature can shift the frequency. its so distinct, right? theres nothing else that would sound like this with this frequency? >> the 37.5 killo hertz was selected because of the background noise in the ocean. >> reporter: randi kaye, cnn, sarasota, florida. coming up,...

Certain victims, what the recovery system may be. those issues remain outstanding. as far as any third party, well, we havent gotten any real facts to determine whether or not theres possible claims against third parties. but, essentially, the families are going to have a remedy under the montreal convention. but what they really want are truthful and honest answers. and some finality to the search. >> jim tilmon, you know, they talked a bit about searching for debris here, not as much as search...
