Would attenuate the sound. alsorts of ways to lose that pinging sound. and especially distance. it may not even be close to it. air france, the pinger itself was at a depth of two and a half miles, so it was quite deep. so you really had to be right on top of it to hear it. >> and the pinger locator that can be towed, it can even get to some of the deepest parts of the search area, is that right? >> well the pinger -- the tpl can go to about 6,000 meters. that will get to most of the area. the a...

Some of the deepest parts of the search area, is that right? >> well the pinger -- the tpl can go to about 6,000 meters. that will get to most of the area. the auv can get to most of it. but there are pockets it may have problems with. >> it had got to be towed at a slow speed, 3 miles an hour, i think. in terms of the area you can search, youre only going to be able to search 150 square miles a day. thats a big challenge for searchers. >> its a very big challenge for searchers, unless they get ...

Use the same ship. they also use it for humanitarian purposes as well. this would fall under that category. what makes it special right now is the fact that it is equipped with this sophisticated u.s. navy technology, the pinger locator, which we can rely on for about a week and needs a more narrow search area to truly search. the reason why they waited this long is they were hoping to have a more narrow area to look, some sort of wreckage to say okay, we found this here. lets look at the ocean ...
