20,000 feet. yeah. the advantage of these buoys, the sonobuys is they can hang just below the thermolayer. above that you can block the sound because the density of the water is different. these can be very quiet. there s no ship at all. these have no ship attached. they are dropped by an airplane and that s fantastic. just perfect quiet. the quiet is an important part of this, mary, because we have the ocean shield which obviously has been taking the lead in trying to track the pings and further pings. we ve also been told the hms echo was going to be moved into that area. i found that a little surprising just for the pure fact they wanted utter silence if possible. well, but once they move it in they will shut down absolutely all unnecessary equipment to try to maintain the silence. moving it in and getting in position will be noisy but then ....
Back of the airplane. they can deploy as many as 80 or so out of one aircraft. the reason i think they were getting the pings out of them because they centralized the location. they ve been dropping sonobuoys all along. but this time they put them in what is already identified as an area of where it s likely to be. so now they re dropping them. they will go 1,000 feet below the surface of the water. i tell you, when you initially hear that it only gets you 1,000 feet below it does offer a little bit of skepticism because you have the towed pinger locator going to a maximum depth of 20,000 feet to listen. why is this effective? well, because what it s going to identify is the farthest reach of the ping. now, again, that s below the thermal layer because the ping sound is going up to the thermal layer and bouncing back down which we ll talk about later here. as that sonobuoy as the pinger is creating this, the sent sonobuoy just has to reach down to get that. ....
Shield, the american provided blue fin 21. the narrower the search field the easier it s going to be for them to be able to gounds nooet the water and find the actual wreckage. very promising developments here in australia. but again, they re still while they re saying they re promising signals they do still need to determine whether or not these are, in fact, from the missing plane. kate? let s dig deeper on this latest news just coming in with mary schiavo and attorney who represents victims and families after airplane disasters. and david gallo, co-leader in the search for air france 447 and director of special projects. good morning to both of you. mary, let me get your take real quick on what erin was just reporting. i hope you were able to hear her. right. i believe this was the first time we ve had a sonar detection, acoustic detection from one of the planes from the ....
They can literally quiet down the ship just as it did with the ocean shield. the ocean shield had to do that as well. the thought with more ears, sonar buoys and the echo along with the shield, they don t know how long their luck will hold on with the batteries. talk to me further about what kind of information this latest detection can offer. they obviously say they need more analysis but what kind of analysis are they going to go through right now to help inform their search? the most important thing is how many sounds are they hearing? can they locate one source on the bottom? can they locate both black box snes that s critically important because when they put that the blue fin 21 in the water they re going to want to throw it like a dart into the bull s-eye. you don t want to take a lot of risks with that, with that piece of technology. every time they get a hit or hear a ping they can narrow down that search zone. how much narrower would they prefer to have it? ....
