Half Ping News Today : Breaking News, Live Updates & Top Stories | Vimarsana

Three separate analyses that led us to this area. the inmarsat data, the half ping, the correlation between the doppler shift and other signatures from other 777s flying through the area. that was good data that got us down here. separately, we have the pings that they found. we have radar data. yes, we made certain assumptions about the performance of the airplane. but it all coalesced in this area. this area is not a little area. it's a big area. i -- i say give it a little more time. >> okay. >> before we jump to conclusions. >> they have less than 10% to go. and michael kaye, you know, alm...

That they can now go on to the next challenge and deal with that, too. >> miles, what's the bottom line for you, especially given you've been frustrated with inmarsainm lack of transparency, do you believe this is the plane? >> i'm an inmarsat believer. the fact that this location happens to coincide with that last, we call it the half handshake, half ping, whatever you like, which we have associated with the last transmission from the aircraft, that, to me, that's triangulating your data and your evidence. and so we got a ping there, and that tells me that inmarsat did an absolutely admirable...

Drift calculations. i was encouraged last night when the australian official said that they thought this might also be the point of impact, or the crash location as well, would be near here too. how they have calculated that is still what a mystery. presumably, they have put the hand shake data together with the aircraft speed and drexel data. if that's the case, they still have the chance to find the wreckage and the very important black boxes. >> the faster the plane is going, the faster it runs out of fuel. so they believe it went down sooner. let's talk about the hand shakes with the plane...

That. let's bring in our experts, david suecy and from wa cnn aviation analyst miles o'brien. miles, i want to start with you. the news in just a few minutes ago, 122 pieces of possible debris sighted ranging in size up to 70 feet. the colors, many of them perhaps brightly-colored. in the area located in a much smaller zone than we've been dealing with today. how significant? >> well, we've had two days of really significant news here, i think, john. we heard about this half ping, if you will. this sort of partial communication between the aircraft and the immarch sat satellite yet which very ...

>> i'm good. i want to talk about this half ping. it came after 8:11 a.m. what might this show? >> i think it is going to have to be carefully analyzed in terms of the timing of the half ping and its nature. it may very well be the very last attempt for the airplane to hand shake with the authorities other means of discovering what's going on through the satellite. it may become very, very significant. right now, it is all part of that same jigsaw puzzle that we have with all those pieces that they have finally located in the debris field. >> so, this half ping, i'm just trying to figure out w...
