Has shrunk dramatically. and it is so much smaller than it was, just a matter of days ago. whether it is a few kilometers or whether it is 20 or 30 square kilometers or even more, no real certainty on that. certainly with those four ping, and also the arrival there of that british naval ship, the "hms echo," which can look at the bottom of the ocean as well and send out its own ping, down to the surface, to see if theres any wreckage down there. theres optimism here they will find the wreckage. ...

A black box is tuesday. youre now coming into saturday. how long are you going to keep looking if you dont hear a ping before you decide to go to the next step, to put that bluefin the water? >> yeah, thats a great question. and thats certainly a decision point. but i really want to stress how critical it is to not put the bluefin 21 in sooner than we need to. just using the tpl is a slow and deliberate process. so it drags through the water. and it listens in for those pings from a black box. a...

The right area but im not prepared to say -- to confirm anything until such time as somebody lays eyes on the wreckage. >> reporter: but with rumors flying, the black boxes were located overnight. angus houston released a statement saying, quote, there has been no major breakthrough in the search for flight 370. over the past weekend, "ocean shield" detected four pings within 15 miles of each other. excitement over a possible fifth ping vanished overnight. the signal, a sonobuoy picked up, was n...

Sonar sonar technicians are sweeping the bottom of the ocean looking for a ping. how do they do it? and how can they fly for so many hours without anyone looking for it. well talk about the delay and the dysfunction in the malaysian response. im wolf blitzer. youre in "the situation room." right now theres new optimism in the search for flight 370. five weeks after the airliner disappeared, australians prime minister says that the search area has been cut down significantly and he is very conf...

Pings or the small short ones that are five minutes and seven minutes and say lets focus on just the ones that we know are within the broadcast area of that box, now, the only one thats really credible as far as that to get distinguishing information is the two-hour ping they got at first. that would indicate that tpl had been towed through the broadcast range of where the pinger is. >> that gives the you the best idea? >> absolutely. >> you are buying the prime ministers confidence? >> if we di...

Intact airplane. something like at least the tail and the wings. the tail being important because thats where the black boxes are. >> youre confident theyre right -- that fifth ping had nothing to do with the plane, right? >> i wouldnt say confident on that. again, im hopeful. it is the right signal. frequency. and the pulse rate is -- makes me very hopeful that, indeed, its a pinger from the black boxes. >> the first four pings that were detected, one lasting for about two hours, one for 15 min...

You know, a couple of thoughts on those sonobuoys. theyre designed to chase soviet submarines. they were either ideally suited for much lower frequency. so the fact that they were even able to tweak them in such a way to detect this higher we frequency of 37.5 kilohertz is, you know, a technological accomplishment and we should give them credit for it. i think thats why we got to be careful about the data that comes out of it. the other thing is, any time you hear a politician talking about an a...

Ago. and the listening area some distance away is much smaller still. that said, not a single verified scrap of the missing plane, nor any of its contents, has turned up yet. and that suspected ping that was detected yesterday by a sonobuoy seemed so exciting for so many. the retire e e ed air marshal coordinating the search. he says, quote, on the information i have available to me, there has been no major breakthrough in the search for mh-370. cnns matthew chance is following the search today ...
