today s unconfirmed news that a chinese patrol ship may have detected a pulse signal in the search area for flight 370 raises all kinds of questions. our renee marsh joins us now from washington. we know the sound picked up by the chinese ship is the standard frequency from the pingers at least from what s being reported and this doesn t necessarily mean it s a slam dunk and there s a lot of skepticism. why? there is a lot of skepticism. this report has really peaked our interest simply because of that key information coming from chinese tv in that the sound was that standard frequency of the pinger 37.5 kilohertz. you have the manufacturer on our air saying this tre quency is unique to these pingers and there s not a lot in nature that
there s other things that are going on. plus, in fact, a lot of times oceanographers will have equipment in the area that also uses pingers for identification. so there is a multiple of different types of vehicles and things that could cause a ping across that frequency of 37.5 kill can kilohertz. so, again, we don t know exactly how the chinese picked this up, what kind of hydrophone, where it was trailing behind their ship, how deep it was. those are the things that need to be answered. and then, of course, they have to identify with at least the gps coordinate, exactly where it was. they should have been hovering, you know, right over the top of that ping area and staying in pretty close proximity. so all of these are still questions that we don t have answers to. okay. let s go, though, with a hypothetical. what happens if these pulses turn out to be one of the black boxes? what is the next step? el the next step then is, of
signal that they re being specific about saying because that is the frequency upon which this pinger is supposed to be transmitting. so from that point of view, you know, they haven t just heard something. they ve heard what they believe to be the right frequency of 37.5 kilohertz per second in the south indian ocean. and the also it s widely understand that can the chinese ship involved has been very much concerned in the efforts to detect the signal of the black box. it arrived friday, north of the area where everybody has been searching. at the th if they have found it, and bearing in mind, we re not entirely sure what equipment anyone has on board, this would be a remarkable finding, indeed. and this would be quite

the story ever sips this news broke and he s joining us live from bangkok with the latest on the search. david? reporter: a possible break through in the search for the missing plane, a chinese ship has reported detecting pings which could be coming from the black box of the plane. the official chinese news agency, xinhua, says chinese patrol ship detected pulse signals in the southern indian ocean. a possible ping sound from the plane s black box were discovered by the ship in an area outside today s search area, about 1,000 miles west of perth, australia. the chinese report, which is believe to have come directly from the ship, said the pulses were on the 37.5 gigahertz frequency, the same as the pings that would be coming from the plane s black box. chinese television earlier reported some of its ships have been moved to the new location. they didn t say why, but could indicate they had a new strong lead for the plane. but it s worth being wary about those reports because there ha
