perhaps a false positive or does it simply mean that there are the other pings were stronger and now it s time to move onto the other search areas? what does this mean to you? from what i understand the first pipg was at the highest amplitude. the ocean can play a lot of tricks on sounds, both from the debris whatever s on the ground, the seaweed around it, the temperature layers. things like that can play a lot of tricks on sound. the pinger is just supposed to get you into a general location. so moving to the north, i think, is encouraging because of the fact that the first ping they picked up was a sustained period of time. it was almost two hours. although the amplitude wasn t nearly as high as the second ping. the first ping was just as promising although it is much deeper there. peter, how do you interpret
now the bluefin, mini sub, bluefin-21 is almost 95% done with the underwater search in that focused area. officials confirm they re going toe to expand it. joining us now with more, mary schiavo. mar mary, good morning. we kind of suspected this, that this may happen. good morning. they said this is an option. they re confirming this morning that they re going to expand it in their statement, how they they ve described it, mary, is they re going to continue to examine the areased a j ed a ja that radius around the second ping. is that unusual or a typical next step? it s a little bit unusual because in this case these pings, these and handshakes, it s interesting how our lexicon has changed, but that s all they have. they really have to expand this. the prime minister s interview with richard, he re-enforced that. he emphasized that they believe
the evidence simply lie with the pings. the handshakes that we have analyzed. that s all we have. reporter: the malaysian prime minister in an exclusive interview claimed that investigators have not had much to go on. he s promising to release a preliminary report on flight 370 investigation next week exactly seven weeks after the plane vanished. many of the relatives of those that were on board are very skeptical. actions speak louder than words. the briefings have been a joke. now, what is not clear, wolf, is whether or not they have any more math to go to, basically, the way that they picked up the pings and how they map where they are searching right now, where will they go next? will they just continue to search around the edges, go to the area of the first ping or reset the entire operation for a
experts. cnn aviation analyst, peter goelz. cnn afteruation analyst, michael kay. aviation consultant, ken christianson. geoffrey thomas, editor in chief of airlineratings.com joining us from pauaustralia. peter goelz, they re going to move this underwater search a little further north based on what, the second ping as opposed to the strongest ping? is that what they re going to do? that s exactly right. i think they re obligated to do that. the australians made a big deal about the pings. they ve said this is the right spot, the investigators have said this is the right spot. they ve got to search the area around each of the pings. so far, ken, the first ping, loudest ping, strongest ping has produced nothing. the assumption was if you get the ping from one of these so-called black boxes, there s going to be a lot of other wreckage nearby. if that s there, presumably other wreckage from the plane would be there but they searched
this is cnn breaking news. breaking news in the hunt for flight 37 o. we have brand new information about what happens next as the bluefin-2 1 finishes its scan of the most promising area of the indian ocean. the operation right now at a critical turning point after seven futile weeks, deep frustration about everything that s gone wrong. our correspondents and analysts are following every new development around the world and right here in the situation room. let s begin once again with justice correspondent pamela brown for the very latest. wolf, just moments ago we learned from a u.s. navy source that officials plan on expanding the subsea search and moving it slightly to north of the six-mile radius if no wreckage is found. this is important because it means the search will move closer to a point of another ping officials viewed as a promising area because of the ping s signal strength and it s a sign they re not giving up in the midst of mounting anger from
