Half Ping News Today

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. its a big area. i -- i say give it a little more time. >> okay. ...

That they can now go on to the next challenge and deal with that, too. >> miles, whats the bottom line for you, especially given youve been frustrated with inmarsainm lack of transparency, do you believe this is the plane? >> im 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, thats triangulating your data and your e...

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 thats 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 run...

That. lets bring in our experts, david suecy and from wa cnn aviation analyst miles obrien. 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 weve been dealing with today. how significant? >> well, weve had two days of really significant news here, i think, john. we heard about this half ping, if you will. this ...

>> im 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 whats 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 the...

Final partial ping you heard so much about. it came from the plane but it was what they called sort of a half ping. well explain exactly what that is and why it could be a game changer in the search. and st. race against time. a construction worker trapped in a burning building about to collapse. this video, someone standing there, she was on her way back from lunch, she was there and filmed this. we have that coming up. ♪ [ male announcer ] when fixed income experts... ♪ ...work with equity...

How, well have views on that. but how or why this half ping is relevant. but if they can prove the integrity of that half ping, then it adds one more if you like dot in the chain and you start to now know a little bit more about where the plane went down. because youre no longer -- youve got another point of reference. and you can coordinate that with how much fuel there was and what point you believe the plane would have been in. >> let me say its great to have you back on cnn though not under ...

A new dplglimmer of hope in finding malaysian flight 370. satellites show a possible debris field. 122 objects bobbing in the south indian ocean. until they can reach them, it will be impossible to tell if they are tied to the crash. it is a possible lead in a search that has not turned up a single piece of physical evidence. another tantilylizing clue, a mysterious half ping. it came in after the last transmission from the aircraft. that half ping is the so-called digital hand shake between the...
