quickly. good question. miranda asks why don t we have live cam ares on planes to when we detect something wrong we can help the innocent and take over and help? the airlines don t want it. i don t know one that shot 149 people at one time. that could be live sent to some place. we ve got the technology. they have to do it. less a question for you from bob. why is the second black box this is for you les so hard to find if pinging like it s supposed to? could the pinger be damaged? well the pinger is used primarily for underwater situations. in this particular circumstance it would have been the emergency locater transmitter because of the impact with the ground. back to the camera situation, that wasn t going to help this airplane. having a camera in the cockpit,
communication system. how could that have helped in the ongoing search effort? that i don t think it would have made any difference. it was deviating around weather and it was normal. they asked for a change in course and change in altitude. they made the course change and whatever occurred occurred very quickly and it took the preoccupation and the focus of the crew to deal with that situation so they did not make any contact with air traffic control after that. air traffic control watched the loss of the target and they were alerted very quickly. i m confident they ll find it quickly. katherine, let s ask you about this. are you surprised no pings have been detected. no emergency locater beacon discovered? i guess one question whether they deployed sonar that would
than the area they already searched. about the size of the state of west virginia. so a lot of searching to be done. and lea gabrielle is here. i heard an investigator say we might get lucky and fine it in a day or two or might take a year 0, or even more than a year. right now searchers from china and australia have been mapping the ocean floor in an area 500 miles south of the air they were looking before. you can see in red, the area they re searching now. and in yellow, this is the area they were previously searching, using devices to listen to the emergency locater, but every ping was another false lead. if we could have spent the time to actually do all the work that s being done now, we probably would have chosen the area that is identified now. but of course, when there was actually beeps picked up that led everybody to want to concentrate their effort on the
transmitting from a part of the aircraft. that s better than debris. debris, that doesn t mean there s a wreck. the wreck could be 1,000 miles away. the fact that it s a ping. everybody s talking about 37.5 kilohertz. kilohertz. does that mean something special to you? yes, it does because there s only one device that i know that emits that frequency and that s this emergency locater. now, if someone wants to mix that up with oceanographics and the song of the whale s call or the tortoise s mating call, they could give you thousands of them. but i m hopeful this is the sound coming out of that flight data recorder. my previous guest told me with this ping from a black box and they manufacture the pinger that it continuously pings and that it gets a little weaker in frequency as time goes on. they only heard this for 90
that if it stops, that doesn t it may have gotten lost or the sound may have been blocked. but that normally it would just ping and ping and ping and ping and not stop. that is correct. that particular ping that comes from an emergency locater, transmitter or black box is a continuous ping. and it doesn t stop. unless if you go far away from the source. and there are times that most of us, we always monitor the emergency frequency as we fly along over water, occasionally we do hear some ping. and sometimes it s another aircraft testing their device or another maybe a small airplane being down. so i approach that with a lot of caution. all right. captain aimer, thanks so much for being with us. my pleasure. coming up, much more on the search for missing malaysian flight 370.
