Engineers understand what this means and how it fits into the big picture. >> at this time, this mission is subject to further ongoing work. >> reporter: is this partial ping a sign that the plane was still flying or is it the moment it went down in the indian ocean? >> this extra data point is not in itself very definitively conclusive about the fate of the plane. it will allow us, should it come to that, to have a some what better -- a somewhat narrower search field. >> reporter: the plane nev...

Even hear the ping, would you bring in the auv to bring in an area with the sonar to be able to map the bottom floor, map the debris on the bottom. >> and see if they can find shadows of something that looks like an airplane? >> absolutely. were not trying to find a needle in the haystack, were trying to find the haystack. were trying to find the arm that the haystack is on right now. >> they are in reserved for when the field gets narrowed down? >> thats right. the gear will land in perth, aust...

Id like to do some peer veeing myself on this. lets see it. >> you know, i agree 100% was him on that. but heres the point. if the integrity of that last partial ping is verified, it stands for the proposition that the search field can be more narrowly drawn and really cut out a lot of area where were currently looking now. it is a very, very important piece of data. the integrity has yet to be established. >> thats the latest information we have. investigators are zeroing in on the pilots. i wa...

Satellites that go around and around, this is geo-stationary. it is locked in the indian ocean. this is the aircraft that uses the acars, now what that does it talk to the inmarsat. when it is a certain amount of miles it automatically defaults to sat com. like, for example, your wi-fi, it automatically locks onto verizon, that is the way it works. we know it was turned off. however, despite the fact it was turned out this satellite will send a little hand shake every hour to say hey, youre stil...

Body of water. so what we wanted to find out exactly, whats the difference between a hydrophone and a sonar? ill introduce you to our new talent resident pundit here. this is james coleman. hes a senior hydrogapher. hes going to tell us how a hydrophone works first. there are different kinds of them, right, james? >> exactly. this is a hydrophone. theyre both varieties. its simply a microphone for use under water. so just like the sound would enter the wet end here. but the difference between a ...

Have never used. this is used in a maritime business. >> would you conceive they are right? >> i hope they are right and we are looking in the right area. but we are not looking back at where the airplanes last decision. >> and because you asked we have this from viewers: how does one evaluate the quality of a ping, and how does the location reveal a path rather than south? i thought he was referring to the black boxes when i saw that question, but i think it is reference to the comment. >> some...

Passively by just listening up to 1 to 2 miles away. the active component of this detection system is submersible. unmanned submersible sonar sends acoustic signals out and can map a wreckage field if they come across it. >> to break it down further, one is ears, listening for the ping and the others is eyes looking for something at the bottom? >> correct. >> all right. now, i guess the task is quite daunting. these numbers, this area is huge. do we only have one of each or because we are runnin...

12,000 feet before disappearing from radar. this says it seems to have been intentional since it would have taken a boeing 777 ten minutes to make that maneuver. last week a u.s. official told cnn they suspected someone altered the flights program path before the co-pilots last call at 1:19 a.m. saying "all right, good noight." now they say the last ping showed a normal route to its destination. if it had been reprogrammed, that change would have shown up in the final transition. >> lets bring i...

>> no, it doesnt. >> yes, it does. >> they dont know exactly where it is. all of the ping suggests that its the 370. they dont know where it is right now. >> i dont know what that means. >> "the new york times" yesterday said that the only thing the ping suggests or tell you is that it was definitely that airplane. >> yes. >> but theres still a very wide range where it can be. >> except that -- except that theres additional -- >> here are the possible positions. >> thats an old and not the right...
