That battery, i would call that the number one challenge we have. there are other things in the ocean that could produce noise at this frequency, that's certainly possible. however, you know, when we initially detected the sound, it was very consistent with what you would expect coming from a black box, and there were two especially encouraging signs. first, is that as the t.p.l. traversed in its path, the signal got stronger and stronger, and then as it crossed where we think the line of bearing was, weaker and weaker, and that's what you would expect as you move toward the signal and then aw...

That is designed to operate at depth. the deeper you are, the better quality of signals that you can expect. and secondly, it's being heard twice by people who are highly trained and actually trying to get the effect that they got. so it's a tremendous achievement when you consider that to get to this very spot to deploy the tpl has taken an awful lot of work by the people in the back room. it's nothing short of miraculous. >> yeah, and i think it was you who said that it was going to take a bit of luck. and maybe a number of people said that, that it was going to take a bit of luck considerin...

Verifying that the latest leads are in fact the missing plane. if it does turn out that the plane is in this spot in the southern indian ocean, it will be so remarkable. remember there was no physical evidence guiding the ocean shield to this spot. it was simply a team of experts who did some amazing math and said look, go here, this is our best guess where you're going to find something. they put down this tpl and happened to hear a ping in the final hours, really, of the black box battery life. we don't have any confirmation yet. it will really be quite remarkable. >> an amazing stroke of lu...

Pinger locator. tpl. that is strapped to an australian ship -- it's what could possibly be signals to the plane's black box. today it is all about re-establishing those things. once that happens, the navy's mini-subwill be deployed to snap pictures of the ocean floor, which could possibly maybe provide concrete evidence of where the plane ended up? be it nbc's ian williams that's in perth, australia for you. >> it is being described as the most promising lead. the best information in a month of fruitless searching. the search coordinator is urging caution. a u.s. navy device towed hinted an au...

Sound under water, may be more prob able when we are talking about the australian ship picking up some audible noise some 350 miles away from where the chinese vessels did. those reports are being very closely guarded. it is being referred to an acoustic event. we don't know what kind of noise that they have heard. you have to remember when you are tieing a tpl through the water, it is on the end of a very long cable, around 6,000 meters or so. you have a lot of cable in the matter and you hear something and you want to go back and listen, it can take many hours to turn around and go back. >> ...
