Perth. many of them taking off from the air base where im standing right now. the two searches that are happening, the one above the water, the search for that debris field that has been so elusive as were more than a month into this. not one piece of physical evidence from flight 370, even though these planes have literally been out and these ships have been out scouring the surface of the ocean. then you talk about the search which is getting so much attention right now, the ocean shield, drag...

Does noise travel, right? so here is the easiest way to put it. low pitch sounds travel farther. so thats why you hear whales at far distances. high pitch sounds travel very -- they dont travel as far. and the pinger is a high pitched noise. so thats why we hear experts say its a two mile radius. and you mentioned the ocean perhaps three miles deep, right? so i said, okay, so if the pingers at the bottom of the ocean and its two or tree miles deep and the radius is two miles, what does that mean...

Dont think its possible. you know, the thing that makes it real hard are the engines. the engines on big planes reflect a lot of radar. now, with that said, apparently, the pinger is the thing that im relying on. apparently, it got all the way out there, with large lely undetected. and i want to emphasize, we had a little dispute before the last break, in my experience, with airplane problems, its never just one thing. its a series of things. and so, this will all be, sooner or later, this will ...

Before any beacon is shipped from here its sound output is measured in one of these huge 50,000 gallon tanks. its lowered into the tank through the floor above. surround by hydrophones, ultrasonic readings are recorded on this computer. this pinger is twa flight 800 which went off the coast of new york back in 1996. this company made the pinger. after it was recover they got it back. this one was found in shallow water but they are designed to function in water as deep as 20,000 feet. what about...

Recorders now appear to have been lost. >> the towed pinger locator work continues. there have been no further contacts with any transmission. and we need to continue that several days. right up to the point at which theres absolutely no doubt that the pinger batteries will have expired. >> reporter: theres more high-tech equipment the search teams are waiting to deploy. like this robotic submarine which can scour the ocean floor. but first, they need to locate the signal again. australian offic...

Tearfully telling what drove him to shoot his girlfriend through the bathroom door and then breaking down as he describes what he saw on the other side. but do his details really add up? also a make or break time in the hunt for flight 370. those fading pings. more than 50 hours since search teams heard the last one. and this is day 32 for those pinger batteries. could today be their last hope? weep got more on those stories just ahead. sfx: car unlock beep. vo: davids heart attack didnt come wi...

Submerged in water. >> we have a positive lead, and it is a herculean task over a wide, wide area, and the water is extremely deep. >> reporter: while the pingers are to last 30 days, the manufacturer says they could go longer. >> they do vary, and 30 days is the minimum, and they could operate as much as 45 days. >> reporter: and now a u.s. pinger locator is being there to methodically traverse an area three miles by three miles to listen to the pings, and each sweep takes eight hours and c e c...

Airlineratings.com, hes joining us from perth, australia. jeffrey, what are you hearing right now from the search? i take it they are still convinced the pings they detected, the towed pinger, thats the real thing, the locator, if you will, they are working under the assumption that they basically know roughly where those two black boxes are. >> indeed, wolf. theres a very high level of confidence that the signals that the ocean shield got, the two sets of signals they got, are the pinger from t...

Matthew, on the one hand, the searchers must be very encouraged by hearing the pings this weekend. on the other hand, by many estimates, the batteries in the pinger should have already run out. do they feel like theyre closing in? >> reporter: yeah, i think theres a sense, or the at least there was 24 hours ago, when this announcement was made, that theyre making good progress. of course, theyre being very cautious, saying that they havent found the aircraft yet. but they did describe these two ...

Is that clear? we will not deploy it, unless we find, unless we get another transmission, in which case well probably have a better idea of whats down there, and well go down there and have a look. [ inaudible question ] yeah. the issue is that if we can get more pinger -- well, more transmissions, we can get a better fix on the ocean floor, which will enable a much more narrowly focused visual search for wreckage. thats the issue. if we go down there now and do the visual search, it will take m...
