Piece together this puzzle really is finding that first piece of debris. >> right. in a way, this doesnt move us closer to answering any mysteries. we have just reinforced the idea this is where we should be looking. i think this is actually going to put more pressure on the searchers to find something and really try to bring some closure. this is a brutal, brutal process for the people whose loved ones were on that plane and for all the world watch to go try to solve this mystery. when air fran...

Outside of perth. ten aircraft, as well as a chineses ice breaker were all participating in the search. >> the u.s. navy is sending a hydrophone listening device to be on stand by if the plane is found and a search for the planes data recorders can be carried out. in the u.s., a team that built an underwater robot is waiting for a request to go to austral australia. >> it can scan wide sections of the ocean floor with sonar. randi kaye tells us more. >> reporter: this robot submarine may hold ...

Timely. the u.s. navy is shipping a piece of vital equipment out to australia today. its essentially a device that is put in the water, towed by a ship and listens for the pings, if you will, from the data recorders and heres -- this has been the big dilemma. this is what were anticipating. if they can find debris and they know where to begin to look for the data recorders, they have to find debris first then calculate where the data recorders might be based on ocean current, ocean movement, ela...

The engines go straight to the bottom and the fuselage too. in the crash of air france 447, the tail of the plane was still floating. experts say the tail of a 777 is made of composite material and it may still be floating as well. >> renee marsh, i understand you have a flight data recorder, talk to us. >> thats right. don, weve been talking about this dying battery on the locater pingers attached to the data recorders. and so this is it. this gold part here. this is the pinger that were talkin...

The ocean is a vast, vast place. well, 17 days now. people are asking as well about salt water and erosion of evidence. this would be pretty quick to start eroding, wouldnt it? >> yeah. the salt water. the depth. certainly if its down at 9,000 or 10,000 feet with the pressure. bear in mind the real evidence is in those black boxeses. and they are designed to withstand this. lets stay focused on that. they -- its highly likely they survive the impact. theyre designed to do that and theyre designe...

Currents to make sure that the planes can get back to where that debris would be. but they havent been able to. partially its visibility very difficult, partially there are big currents there, its a big stretch of walter and theyre having real difficulty. >> in perth, australia, andrew stevens, thanks very much and good night. ultimately nothing will be more important in this investigation than this noise. [ pinking sounds ] surprisingly soft but that is the ping from the planes black boxes whic...

That we have finally got this audio, because we have been talking about the pingers and the pingers and pingers and finally now we know what we are referring to. and that audio is exactly what the pingers aboard flight 370 would look like if it was detected by underwater technology and normally you cant hear it with the human ear, but the manufacturer helped us to convert it to an audible pi pinger. they are, as you know, associated with the flight recorders, and those flight recorders are so cr...

It keeps us out of the way of any obstructions. >> reporter: these types of searches can take months or years but the payoff is high. wreckage that gives clues about what happened, data recorders, and the thing that matters most, the fate of the people on board. >> so the auv narrows your search, it finds the actual wreckage and you step it up with something called an rov, a remote operating vehicle. its a robot that goes underwater, it has high definition cameras and little hands or claws that ...

Bottom. keeps us usually out of the way of any obstructions. >> reporter: these types of searches can take months or years. but the payoff is high. wreckage that gives clues about what happened, data recorders, and the thing that matters most, the fate of the people on board. so once you find that debris field, then you step it up with something called an rov. a remote operating vehicle. what those are, these are underwater robots that use high-definition cameras and robotic arms or claws to ret...

>> translator: mysteries of the disappearance are no mind boggle nothing matter your nationality everybody is interested in what happened to the plane. >> reporter: with four missing french passengers it has been front page news. undoubtedly fueled by the parallels of the disappearance of flight 447 that crashed off the coast of brazil on its way to paris some years ago. it took almost two years to recover the voice and flight data recorders. >> obviously for any news organization its a big prob...
