Is. there are, at a minimum, 15,000 ships, on the worlds oceans on any given day, creating even more obstacles in a search thats already daunting. rosa flores, cnn, narragansett bay, rhode island. >> rosa, thank you very much for that. that gives you some idea of just how difficult this search will be. my expert panel back with me right now. i want to start with you, paul. do you usually know a ping sound when you hear one, even at that high a frequency? >> well, there are signatures that are st...

Giant map. somewhere in the south indian ocean here trying to recreate what some of the technology is being used to look for, the pinger. weve talked about this. its a little heavy. jeff, you can hold it. >> okay. >> lets turn it up. this is the device that theyre using. and we can already hear -- >> right. were actually picking up the ping thats released by an actual pinger like the one on the plane. >> this is the one that the chinese were using. >> right. this is a handheld version. this is d...

>> welcome back to our breaking coverage of the search for flight 370. heres what we know, pings detected in the indian ocean could be from the planes black box. the bigger could is could this be where the plane came to rest. a lot of speculation. we have mary schiavo, aviation analyst. and mr. miles obrien, cnn aviation expert. mary, i start with you, make a case for why we should all have grace confidence in the pinger locator possibility? >> sure, it sounds like they heard the right megahertz...

David kelly, president and ceo of blue fin robotics the company that makes the submarine that effectively will be used to look for debris, and thomas atsheler is the vice president of the company that makes the pingers as well as the equipment that the chinese were using to hear the pinger sounds earlier on, before this even larger find this weekend. so let me start with you, if i can, tom, and that is the tpl-25, this remarkable piece of equipment the u.s. navy has supplied which has effectivel...

This is a spectrum of what the frequencies are in the ocean. its ocean noise. if the pinger is heard, it will see a spike here. >> that is one thing that is helping us. and the other technology is what the sonar is picking up. >> the sonar is building up sound and we are getting back an image of what is on the floor. we have a 3d point cloud and an image and we are building slowly a map of the floor. >> how long does it take? >> its time consuming. particularly because you have to get these sens...

So call... to talk with an insurance expert about everything that comes standard with our base auto policy. and if you switch, you could save up to $423. liberty mutual insurance -- responsibility. whats your policy? >> two ships in two spots heard potential pings 370 miles apart. are they hearing the same pinger or is one of the ships picking up something else perhaps? the signals that chinas ship heard were picked up using an unconventional method. there are also good reasons to believe it. nu...

The gear you make, to your gear. you listen for the boxes. you look for the gear. i want to start with the pinging. im not sure if i understand clearly, thomas, why it is that you can listen for two hours to pinging and, here we are 12 hours later, we havent redetected it. >> the trajectory, how the boat is moving across the water, where it is close to that device that they heard or what they think they heard, is very important. it has to be close enough to hear it. miles make a big difference. ...

It was considered a hail mary pass, a last ditch effort and low and behold it did find something over the weekend. now comes the hard part. they have got to go back over the area where they detected this. they have got to reacquire the signal. its going to take parallel runs and perpendicular runs so they can home in on it, triangulate it. and the animation that youre looking at now, thats another device that theyre going to deploy. that is blue fin 21 which is going to go down and take pictures...

There are two main areas of focus at the moment. the one is where the chinese vessel 24 hours ago announced that it had two acoustic events. it found two pings or pulses underneath the ocean in two separate locations, two kilometers apart over a time period. they sent that british ship, the hms echo in order to investigate that, to try and verify it because there has been no verification its been linked in any way to the malaysian airliner there is a second area as well. thats the australian ves...

Black boxes that they managed to locate this area without any wreckage discovered whatsoever? >> i guess the best analogy right now, since we are into march madness, this is the buzzer beater from half-court. this was a shot in the dark. they had some good idea of where they were at. its not clear how "ocean shield" had been out there but this is an incredible great piece of luck. >> arnold, have you ever seen a situation where they have located the two black boxes before they spotted any wrecka...
