For the boxes are expected to run out. its almost too good to be true now those ships split todays search area looking for confirmation signals picked up were in fact what they were looking for. could this be a step towards some finality for families or just another false alarm. tom foreman joins us at the magic wall. >> reporter: at this point, i guess it depends whether you think they are really good or really lucky or maybe either one. thats the problem. we dont know the answer. look at this ...

Bend, sort of making this even more difficult to trace. >> thats correct. bend quite dramatically. the effect of temperature, pressure will have an effect on the velocity of sound as it travels through the water. and this will cause the ray path, the direction in which the sound is traveling to actually bend sort of like looking at a pencil in half a glass of water. the same sort of refraction that occurs there. so it can be very difficult to localize. >> if they localize it, if based upon this ...

International experts, they have to be within three to four miles of the location of something on the bottom that is manmade and the only thing that really should be down there at this point would be the pingers. so if youre looking at something, even conservatively, youre talking about 75 square miles, which they already have narrowed it down to. that makes this a very trackable problem. >> in the air france disaster, they never heard any pings to begin with. at least now they believe they hear...

Are taking pictures and sonar on the ocean floor. if you have any ping to work with, and reestablish that ping, you have to go for it while it is theoretically possible. >> thats right. you will want to stay with us as we cover every advance and setback for the search for flight 370. look for updates on "america this morning" and "good morning america." a group of u.s. sailors once again suing the fukushima power plant. the sailors claim they lied about radiation in the area where they were ca...

Cred. if he can wear a medallion -- >> hes playing to racism and playing to information and marginalized small -- weve got to go. appreciate it, thanks. how close are officials we have new developments in the search for missing malaysia flight 370. they think theyre getting closer to the ping where the black box may be. when we come back. woman: everyone in the nicu -- all the nurses wanted to watch him when he was there 118 days. everything that you thought was important to you changes in lig...

From. >> acoustic energy, sound through the water, is greatly affected by time, pressure, and salinity. >> reporter: if "ocean shield" hear hears another ping and is able to fix the position, it will put blue fin 21 into the water and attempt to find wreckage on the sea floor. if wreckage is located, one aspect may work in investigators favor. very low temperatures. >> cold temperatures does preserve things better than a shallower, warm temperatures. >> reporter: the search continues. >> and wha...

Just because we can hear pinger and possibly might be able to locate it doesnt mean at that moment we found the box. the box could still be several hundred yards away if not more. so still yet another layer of concern. were still a long ways from finding a really meaningful data, meaningful information to. he out. >> adding yet another variable to this unprecedented search. well continue to watch it. another day to try to reconnect with that ping and search continues. thank you so much. >> thank...

Miles. in a circle, if you will. and it detected on another track, the same pings, and yet we have another circle of six-mile diameter. if we could get a different, a third line of position, a direction that the ship is steaming, with yet a third circle, we overlap those circles, and at the point they overlap is the most likely location for the wreckage. >> i get it. the ballpark, the neighborhood is still way too big for them, even though they have this ping. so depending on the triangulation, ...

From malaysia 370s black boxes but they say it is their best lead yet and to expect several more days of intense action to try and track that signal down. clayton sandell, abc news, perth, australia. >> so the question is, what happens next and why arent they sending the submersible device down to look for whatever might be down there. wreckage or black boxes. lets just get something going. but experts say it is almost impossible to send anything down and expect it to find it out some kind of di...

Caution show cautiously optimistic. the task now the ocean shield is trying to find the signal again and hoping for confirmation. if the ping is detected again crews will launch this underwater drone. at the same time 375 miles away, chinese ships and the british hms echo are trying to confirm pings the chinese briefly detected friday and saturday. australian officials say its unlikely to be from the same source. >> quite possible for sound to travel great distances laterally but be very difficu...
