unless it s a very well-trained mammal, who has good laboratory technique. we can measure to ten thousandths of a second on the repetition rate. and we expect that not to vary. and we talked about certain signatures, because you have certain repetition rates and certain signals and all of that. and some aquatic life or ocean life, an animal or mammal would have to do the same sort of thing in order to repeat that and that s highly, highly unlikely. let s move on now. leyla says, where exactly are each of the black boxes located on the plane? jim tilmon? well, there are a number of places they generally put them. generally, most airplanes will have the boxes in the tail, in the vertical fin. some place, they think, is going to survive the worst part of a crash. a few of them have been, from time to time, put further forward and high in the fuselage, but most are near the

make a map of the ocean floor to see what s under there. to see if we can find some debris, large or small aircraft debris and hopefully that black box. thank you very much. stand by. geoffrey thomas is with us. mary schiavo is an attorney for victims of transportation accidents. ocean explorer, tim taylor. jeff wise. jim tilmon. the batteries may already be dead. do you believe the data recorders will ever be found? if the pinger is dead and there s no debris on the surface and we re convinced it s along this southern arm, then what
start making some definitive plans with plan b in mind. i have an individual approach to that. i want to go back to the last known absolutely documentable location for the airplane. then the plan b should start from there, as if we haven t done anything else any place before. nic robertson addressed this earlier. do you think the malaysians should release the audio recordings of air-to-ground conversations with the cockpit, jim tilmon? here in the u.s., you can listen to the cockpit at any time because it s streamed online. isn t it stunning that they won t release it? i m amazed the malaysians and what they have conducted this thing and what they consider to be secret and all that. where were all the radars? the malaysian radar was going, how long did it track the airplane? even the one in australia, i m told that s one of the most
