the 33.3 megahertz frequency, that s a big problem. it may be explainable do to some of these factors that bill nye was talking about. it may not be. we have the fact that we had over false positives in recent days. and i want to bring us something that someone mentioned to me in an e-mail, but i haven t heard mention on air. there s a simple math problem that if the ship is pulling the tow fish along at 3 knots and the tow fish can detect the signal within two miles, basically, you wouldn t expect it to retain a signal for two hours. there seems to be a fundamental mathematical problem right there. and you add on to that that they weren t able to reacquire the signal, in the most recent day of searching. it starts to add up to a big problem. bill nye, our science guy, do you want to weigh in on that? do you agree? i don t disagree, as the saying goes. it depends. it s very reasonable, as crazy as it sounds, that they got the
captain tim taylor is a specialist and president of subsea service. steve wallace is former director of federal aviation administration office of accident investigation. miles o berry scene a cnn aviation analyst. gentlemen thanks for being here. tim i want to start with you. we know this frequency came in at 33.3 kilohertz lower than the standard 37.5. does that rule out that this is possibly from the black boxes? no not necessarily. the battery strength water is a very diffuse medium and full of layers of temperature and pressure gradients that can distort and reflect this, so i think that it is in the range. these manufacturers always say that they are plus or minus on the range as well so not always right dead on. and if you factor all that in
the original immarcet pings. it s the seventh recalculation used by bringing in more evidence on the radar tracking of this aeroplane. and the location is exactly on this track that the ships were told to go and have a look at. so there s some supporting evidence that, yes, they are the black boxes. we listened to this press conference live from angus houston, paul. you were optimistic about this, but now cnn is hearing that the frequency detected was 33.3 kilohertz, not 37.5. do you still believe that these are, in fact, the pingers, and is it an exact match? is 33 that close to 37? okay, we re talking about 10%. and we had a discussion this evening before air about the effects of temperature gradients on the transmission of different
listening. they feel they re in the right place. not just because they went there and they heard these possible pings over the weekend, one for two hours, one for 15 minutes, they feel they re in the right place because of all the data, all the experts in kuala lumpur who told them this is the place you need to look. they went there with the ocean shield. they dropped in this pinger locator. they heard pings. they don t think that s a coincidence. i want to go to tom quickly. the latest news is the australian defense minister has said about dropping a whole load of son delawaar to try to find debris. that s one of the reasons you use the sonar buoys. they also have a detector so they can detect at 33.3 kilohertz which is the frequency being reported right now. so it s a double sword. you re going to see the
the towed pinger measures intensity, but not position, so multiple hits are crucial in triangulating a smaller search area. until we stop the pinger search, we will not deploy the submersible. is that clear? we will not deploy it, unless we find, unless we get another transmission. this is the submersible, bluefin 21, the underwater drone moves along at a painstakingly slow pace, mapping the ocean floor. the pinger manufacturer is analyzing the recording. it s actually at 33.3 killlow hertz, lower than the standard 37.5. a change possibly due to environmental factors. there s a change with the pressure on the ocean floor, and the age of the particular batteries, the capacity can change, and you get changes in
