Right? it has been 32, 33 days. how much longer can they go? >> well, the batteries and the requirement are 30 days. our product has exceeded that. were extremely proud by that. our testing has indicated that we should be able to get about 35 days. so were hopeful it will continue to ping. it is pretty overwhelming that you have an international search coalition and they are looking for our product. they have outperformed the expectations. another thing i dont quite understand. they heard someth...

Go long. >> welcome back. im brook baldwin. just when it seemed the trail was literally going cold, new sounds were heard in the ocean. searchers are now optimistic. this is their word that these could be from the pingers. see this graphic here. this brings the total to four possible black box signals. all of them located within 17 miles of one another. by the way the two signals here are more faint than the previous ones and the man in charge believes that these ping

Black box, one part of their optimism. the other, as you pointed out, detected them. this time the signals coming from the black box are weaker and that is frightening because they could die any moment. they were only able to stay on that ping about seven minutes today. >> in one of the two cases. >> so this is really a race against time because unless theyre able to locate where the black box is, where the wreckage is, the job becomes really difficult. >> theyve made it clear these batteries do...

Looks like. let me introduce you to james coleman. lets take a look at pinger, because its smaller than i thought it was. >> an emergency locator beacon used in black boxes. this is the pinger sending out 37 1/2 kill low hertz sound. >> this is whats picking it up, right? these are hydrophones. >> different examples of hydrophones. come in all shapes and sizes, underwater microphones, used in a pinger locator to pick up that pinging sound. >> reporter: when it picks it up, it doesnt know were th...

Calculation and ping seven. thats another source of evidence. so i think that were looking in the right area. but im not prepared to say, to confirm anything until such time as somebody lays eyes on the wreckage. >> are you being cautious for the families and the sake of precision, but we are looking at a case where we have frequencies, which are consistent with a black box. thats been verified by the black box. by acoustic analysis. they have been consistent, they have been sustain td and they ...

Yet, no piece of flight 370 thats been spotted or recovered in the indian ocean. we have four pings. theyre going to continue listening as long as they can to try to zero in on the location. each time they hear a ping, they can get a better idea of where these data recorders might be and thats when theyre -- the next step would be to actually deploy the submersible and go down and take a look. theyre actually not there yet, they want to keep listening as long as those black boxes are potentially...

Vehicle. why not? >> thats correct. the sensors, theres two different sensor packages. theres a sonar sensor package that has side scan and some other sonars and the camera is in a separate payload. that is done because when you are doing a camera survey you are flying closer to the bottom, approximately five meters off the bochlt at that height the sonar return and imaging is not as good. no sense in having the sonars on the platform at that time because the two sensors operate from different a...

Moment. but colleen, how many more pings realistically do you think they need to triangulate, if you will, and get a much better location of where the box or both of those boxes are? >> well, i mean, every second, every new ping that we get, wolf, puts us that much closer and will save us time when we go to the underwater search. but really if you think about it, we dont know what the bottom looks like yet, and i was thinking about this earlier. imagine if one or two of these boxes landed in a c...

And they recalculated it. and this is the line that the "ocean shield" has been searching on. also, its exact location now and the location of these pings is also where inmarsat, the british telecommunications company, says the last handshake, they feel like the last ping from the plane was recorded. was at this location. so theres a number of corroborating part of this jigsaw puzzle that give them a very high degree of certainty that theyve got the location. >> geoffrey, it seems to me now that...

Is the exact path followed by the ocean shell as it was dragging that ping indicator out there. this is where it pick up those various pings, those four pings. now, i mentioned the satellite track, the satellite track actually runs right about here. so this is remarkably close to the area that they were aiming for. if you look at all of this, that just looks like a hodgepodge, well, theyre going every which way. not so. these are the rudiments of a system out there, which allow them to tighten t...
