Saturday for that two-hour period. that says we are in the right area. >> david, what kind of further research can be done on those last pinger locations if theyre within a 17-mile radius? what can researchers do and searchers do with that last bit of information to try to pinpoint a pinger or a black box, whatever originated that sound? >> well, theres a couple of things. we talked about triangulation before and when you have one point, you have a straight line to work with, so if you put circl...

>> i think were past satellite imagery at this point. any debris field that might have been floating is not -- very far from there. i think its possible the pinger to reduce the search field, to concentrate where to look for it next. >> i want to show you the latest flight map that we have that shows what the folks from kuala lumpur and elsewhere think the plane did which was, we pretty much know it headed west and then south. this trajectory was given to us saying that the plane flew deliberate...

Around those pinger locations because thats the only other bit of evidence that weve got. once we do that, then well move into the next phase, which is to work out whether there is something nearby the pingers, whether its verified or whether we need to go to a much wider area around the pingers. >> rob, van, bob, mary, thank you. appreciate that. next, we speak to a man who shares his perspective on the search. hear why james cameron says the ocean depth is not the only problem. gunderman gro...

David. is it possible with your experience with these units that it can actually record more than two hours, or do you know for sure its strictly two? >> it records over it again. they made sure what was on there before is not retrievable. >> heres my question. how long before they find the black boxes? >> you know, i hate to speculate on behalf of the families. i want to qualify this and say -- >> you have done this before. you know a reasonable amount of time. >> absolutely. what i would say a...

Todays search update from the joint agency coordination center. big headline there, there have been no new acoustic detections in the past 24 hours but the search for the elusive pings continues. australian vessel, ocean shield, combing waters with american towed pinger trying to detect any signals. hsm echo by its side. efforts by air as well, stralgian sstralg i australian surveillance planes over head. it has to be said it has been silent since tuesday. no new pings since tuesday. authorities...

>> why? >> well, because they are clearly getting more and more confidence in the equipment that they are using to try to pin down where the aircraft went in. so they are more comfortable with what they have now. the fact that it is larger than what it was before, that just means that obviously they are more confident in the accuracy of that and its progress. >> for those of us not in the business of this aviation expertise as all of you are, i think most of us would think that to triangulate an...

Let me bring you in first, simply because it seems to me that for the purposes of this conversation, lets say that the pinger batteries are dead. now we go to submersibles. what is the primary mission right now? >> the primary mission really is to find debris field on the seabed and hopefully, it will be somewhat recognizable. it could be really broken up, but usually, get something like the tail or wings or cockpit that might be recognizable, even by sonar. so, once you find that, specifically ...

Those batteries of the black box pinger have completely expired. the question now being when exactly are they going to feel comfortable to make that assumption and deploy the underwater autonomous vehicle to find the physical wreckage, isha. >> 37 days into the search for flight 370. erin mclaughlin there in perth, thank you, erin. not much is known about the seabed in the southern indian ocean. its one of the most remote places in the world. in fact, its said we know more about the surface of...

You are hearing simulations what the sound is. its also at 160 decibels. think about how loud that is, its very loud, ten times louder than osha requires hearing protection for humans. so its 160 decibels, about as loud as a gunshot. if you think about being in the mountains and shoot a gun or hear a gunshot, you have no idea where thats coming from, you hear the gunshot. thats where theyre at right now. but there is a region you have to stay within, where that pinger did the first time, two mil...

Continuing to expand. putting it on the what you have level and the factual level, the pings are the same, the locations are the same, spread out about 17 miles, so that area still the find. its no worse than it was two or three days ago. they just dont have anything to make it better. i really see theyre pretty much in the same position and just waiting to put the submersibles in. and i expect that will come in a day or two. >> david, do you think thats a day or two away and how confident with ...
