aneesh patel president of seacom which makes the pingers for the black boxes. will, you interviewed a professor that said something extraordinary, that we know something about the surface of the moon than we do about the floor of the ocean. isn t that incredible, carol? there are concerns that because we know so little about what actually lies beneath, that the extreme depth that we re talking about may actually push the limits of that bluefin-21 submersible. it is rated the maximum it can go down is 4500 meters. that s how deep the water is in this area. for reason it s even deeper, if our estimates are incorrect, they might have to bring in different submersible which will take quite a long time. we ll find out when this thing comes up. maybe this time tomorrow we ll have more information about how it looks down there. right now this tiny submarine is under water, will, right? tomorrow we expect to have some
of the anomalies. get as many direct signals as they can, erin and then maybe a much smaller box. tom, thank you. that is why they re rushing to race against the clock, why what they have now isn t enough. they need more. they need more to get this exactly right. richard quest joins me along with aneesh patel, president of duquesne sea com. authorities have confirmed at least one of this pingers was on board flight 370. they re saying the signals they picked up are weaker than what they got over the weekend. now we re possibly past the battery life. how much longer do you think the batteries have? well, we build in a design margin of about 10%. so we think they re going to go a few days longer than 30. after that, we call it bonus time. the battery is going to start to degrade. it sounds like we re in that period right now. so it could be a matter of days. in the lab we have experimented with this under laboratory conditions. we can get a very faint signal
