. day 34 since the boeing triple 7 vanished with 239 souls on board, yet only the start of day two, in the underwater search in what experts say is most certainly a black box pinger. the officials are certain they will find not only the black box but the plane, they are becoming more real. well explore them tonight. first the very latest from michael holmes at search headquarters in western australia, so what do we know about the latest search efforts under way right now? >> yeah, it is -- wer...

>> actually what we have now is only one really strong signal. that was the two-hour one. these others, one could be skirting the outer limbs of what that pinger can radiate out. so youve got the pings coming out. now, the others out here could be one of two things. either theyre inside here and the battery is getting weak but we kind of know thats not the case. its been going for a day. lithium batteries dont slowly degrade over days. they will degrade and then theyll stop. >> and potentially d...

Thats why you want to get as many of those pings to box off the location where you would ultimately put that unmanned vehicle in. >> you used to do these investigations, peter, at the ntsb. if you were involved in this one, is there anything that you think you would need as an outsider that they are not getting right now? >> no. i think the investigative team and the search team has got every piece of equipment that they need. theyve got everything that theyve asked for. what they need is a litt...

Up those underwater signals on saturday and tuesday is carrying a u.s. navy pinger locator as weve heard and been reporting on. >> this really is a key piece of technology because the more pulses investigators can detect, the more theyll be able to narrow down and zero in on flight 370s locator beacons. >> joining us now, commander, thank you very much for your time. first, walk us through what specific mission your team is involved in today. >> sure, as you know, on the ship, we have the two in...

That were down to five now, although the sounds are getting weaker and weaker? >> theyre getting weaker and weaker. but that is exactly what you would expect from the battery in its last days as it gets weaker and weaker. the signal, the output of the transmitter gets weaker and weaker. so its behaving exactly like you would expect the pinger to do. the fact that you have five of them after a while, it walks like a duck and quacks like a duck, its a duck. >> what do you make about this report th...

In different places. at that time he seemed to suggest they were coming from the two separate black boxes. >> absolutely. you know, if it is only from the flight data recorder, remember the cockpit voice recorder has a two-hour loop on it. youre going to get a lot of information from the flight data recorder, particularly if there was no real conversation going on going on in the cockpit. >> this is the flight data recorder, peter, as you well know. this is the little pinger over here that sends...

Looking for any debris that they can find. they need corroboration. they have the circumstantial evidence of the satellite pings and the ping noise. but they need corroborate bing evidence. >> two things going on here, the planes are looking for debris on the map. and then the pinger in the ocean shield is still trawling up and down for five or ten days until theyre absolutely certain the batteries are dead. but the planes are in the air looking for the corroborative evidence that it exists. >> ...

That theres a lot of silt down there. that could complicate the search because the silt on the bottom of the ocean can be very thick and things disappear in to it and it makes a visual search underwater very difficult. >> on monday, you thought there was possibly two pingers. to you think you are dealing with two or one device at this point? >> well, we have the evidence. the assessment was made that we thought there might be two pingers there. this has not been confirmed in further detections t...

Of this journey is certainly going to be the hardest. thats how deep, give or take, the ocean is where those pings are being picked up. and tracing them back takes a whole lot of know-how and probably a pretty serious amount of luck as well. im joined now by cnns meteorologist chad myers in atlanta and from boston the vp and general manager of the company that makes and designs undersea communications gear, including the pingers and also the pinger detectors. chad, i want to start with you. will...
