Extraordinary. we dont, for example, what pinger location equipment its got on board. we know the "ocean shield" but we dont know what it has on board. one other point, and im going to be a little skeptical on this, of course. youll remember, it was the chinese that brought out the satellite photographs very early on in the investigation. very early on in the investigation which turned out to be in the wrong part of the -- in the northern part of the south china sea, exactly the location from wh...

Frequency. so it doesnt pulls out very far. thats why over the last month we have all been talking about the fact that you literally have to be almost on top of that pinger, if you will, to hear it. youre not going to hear it 20,000 feet from the pinger. it just doesnt have the ability to radiate the signal like that. so, you know, one of the things that we really have to be cautious with, of course, is other ships in that area. there are other generators of that frequency of sound, or at least ...

Sending it out to begin with had it been damaged in the crash, then no. our system wont locate it that way. >> i imagine that there is a lot of noise in the ocean. im wondering what other natural sounds could be confused for the pinger. >> there are a couple different types of sounds in the ocean, tectonic sounds, whale sounds, that kind of thing. but the processor is able to distinguish the sound the pinger makes. >> this is a tweet from james. if the pinger locater gets a hit, how long does it...

Chinese patrol ship searching this effort to find flight 370 has detected a pulse signal at 37 1/2 kilohertz per second which is the exact frequency a pinger on a black box sends out that ping. weve got our panel here covering this search and this investigation from many different angles all around the world. i want to go straight to pilot dave funk. the discussion up to this point has been searching for debris and hopefully that debris field would lead searchers to the black boxes. it has to be...

Get that towed pinger locater down in the deep ocean. the block box can get stuck in something called a deep sound channel. about the 2,000 to 4,000 feet below the surface. if the sound does get trapped there and bounces around, the only way to pick it up may be through one of these pinger locater devices. >> sending the towed pinger down there, the tpl, will put you in that channel so they can hear that echoing or ricocheting sound. when it picks up the sound its in real time sent up the cable ...

Technology that now has an active role in trying to solve this mystery, the mystery of flight 370. >> reporter: this high tech listening device can glide along near the bottom of the sea at about 1,000 feet from the ocean floor. its a u.s. navy hydrophone or underwater microphone called a towed pinger locater. search teams are counting on it to find the pinger mounted directly on the black boxes from flight 370. but time is running out for the pingers battery life. >> what theyre trying to do is...

Recorders will ever be found? >> if the pinger is dead and theres no debris on the surface and were convinced its along this southern arm, then what were really facing is we would have to go down and try to locate this thing with side scan sonar, which is equivalent of riding around the continental united states on a horse looking for this thing. its getting extremely slow process. if you deployed multiple underwater robots, this could take decades. >> tim taylor, how does a search plan change, ...

That yet. why wouldnt they be? >> well, brooke, the primary purpose of the existing pingers is to locate the actual location of the data recorders and voice recorders within a debris field, not to find the debris field itself. their short range makes them not really adaptable to a wide search area. thats what were faced with. what were trying right now, the australians and the navy are trying, sort of a low-probability last-ditch effort, if you will, to try to get a signal from their best idea o...

Die. >> the pingers could already be dead. to find the pingers after they stop is going to be extremely difficult. >> i want to thank zain azure. we are assuming a lot about the black boxes. if and when they find the black boxes will the data be able to be extracted as we saw in the piece? >> the data will be able to be extracted. there are very few cases that i worked on where it hasnt been, most notably were the two planes that went into the world trade center on september 11. those black boxe...

Ocean, including australias "ocean shield," that vessel is dragging a pinger locator from the u.s. navy, hoping to locate the black boxes before their batteries run out, which will happen in a couple of days. all america air carriers from traveling through crimean air space, after russia takes over that air space, which has caused confusion and potentially dangerous flying conditions. theres already been one incident in which a carrier was getting instructions from ukrainian and russian air cont...
