Again. crews will scan mile after mile of ocean on this the 37th day after flight 370 kept missing and we keep hearing words like optimism and confidence related to this search, but the pings that are thought to be from the planes black boxes have not be detected since tuesday, thats five days leading to fears the batteries in the data recorders are becoming too weak to transmit. now, relatives of missing passengers met today with malaysian officials. one mother says she feels like the malaysian...

Travels less quickly than it does below it or above it. there are a lot of different reasons for it. the selenity, the temperature of the water pressure, but the results are a level of uncertainty that you dont want to see in an operation like this but you have to deal with. for example, if a sound comes up like this and it hits that layer because this is slower it can bend at a very substantial level so that when it emerges it is not at all where you would expect it to be, over here, for exampl...

To 30 days. so probably at 35 to 40 is where they will start to degrade to the point that the pulse or the ping wont be audible by the pi pinger rays. >> so whats the next step in trying to find the plane? >> well, theyve got to narrow it down using all the hits that they have, and then visual confirmation. so once theyre confident theyre not going to receive anymore pings and believe the batteries are depleted, go down there and visually inspect the best area where they got the highest signal o...

Down to about three miles down. i think we can show you some pictures. quite an extraordinary device. see if we have footage of that. there it is. what that will be able to do is called the blue fin 21, is go all the way down to the ocean bed, which is three miles down. it goes very slowly down there. it cant cover the area in the same way that the ocean shields pinger detected it was dragging at 4,000 feet can do. so basically it will be a slow process, heavy going, but it has a much better cha...

Doesnt use the sonar picture at all. it is actually taking a picture of the ocean bottom using sound or optics. you have to remember there are many crashes in the ocean where we never have a pinger or it completely failed. air france 447, the pingers were never heard, but they can do it. if this is clear, they will see it. >> david, regardless of which country ends up with the black boxes, there is still this issue of who is going to pay for all of this? how ultimately will this all get sorted o...

Ridge, this is an outline, if you were to tip washington states iconic mt. rainier upside down, you get to the peak of it at about where the pinger is. 15,000 feet below the water. that gives you an idea of how far this locator has to pick up a signal and where the black boxes are likely. christi. >> you dont want to say where is it. it is not that easy. after more than three decades on tv as we switch gears here, were you surprised to hear late show host david letterman is retiring. we are inte...

To find the senate again? the prime minister said its fading rapidly, and that could indicate the batterys powering the pinger are already dying or may already be dead. the pings were first heard last saturday and then again on tuesday, but nothing has been heard since. on saturday, four team ships and ten planes involved in the search more nan 1,000 miles off the coast of australia focusing in on an area about the size of massachusetts and connecticut combined. lets start in perth, australia fo...

They can survive up to 40 days, you have to be right on top of the device to hear it. what we have here is our 90-day pinger which will be installed on new aircraft starting march of 2015. these have longer life and identical to the 30-day device, but give the searchers an additional 60 days of battery life to conclude the search and try to triangulate the location. >> mr. patel, two pingers. one in front of the plane and one in the rear of the plane? >> correct. each flight recorder and the voi...

Its been several days, four fading. days since weve heard anything or at least officials heard anything. what is that telling us about prap perhaps the location of these pingers or could it be buried in silt? i wonder, would be, if you could address this? or is this as simple as the battery is dying? >> i think its as simple as saying that the batteries are starting to fade away now. they dont just cut off at a certain day. they gradually lose power and get weaker and weaker. i dont think the bl...

With the sound of the pinger like sea life. one dolphin species sounds like a black box pinger. and this is the sound of rain underwater. let me get away from the loudest part of the boat so i can show you one of the biggest obstacles that searchers have in the open sea. just ship noise even here listen to how loud it is. theyre at a minimum 15,000 ships on the worlds motions on any given day. creating even more obstacles in a search thats already daunting. >> rosa flores joins me now. rosa, gre...
