cockpit? i m in favor of anything that enhances safety. and i m with richard on a lot of his points. however, a camera can be subject to misinterpretation. i mean we saw what happened with various police videos what really we saw and what really happened cowl be two different things. so the other part of it is here s our fear mostly is pilots is that it can be used as disciplinary type actions rather than something to enhance safety down the road. and then as richard said it becomes what we call tombstone technology. once you utilize that unless it s live streaming data tax all it does it enhances the cockpit voice recorder and what you have left from the flight data recorder. if we can have systems in place where it s not a disciplinary situation for a pilot, then we could start talking about that. david, let me ask you this. also what is being discussed is changing possibly changing how cockpits are constructed, the lock on the door that it is
as the search for airasia flight 8501 has unfolded what questions are on your mind and you ve been answering us with your questions. joining to us give you some answers is cnn aviation analyst les abend. he s a 777 captain and christianitying editor to flying magazine. this viewer asks can you ask why the black box doesn t have a floatation device attached to it. the military has something. the technology is already there. why don t we already have it is perhaps cost. because you have to weigh the benefit of this this is what we call tomb stone technology. this is after the fact. what now let s prevent the accident from happening rather than determining why it happened in the first place. but it s not a bad suggestion. this has come up before.
reporter: bluefin robotics makes submersibles autonomous under water vehicles built for exploration, discovery and defense. but more recently their technology has been used for airplane search and recovery including malaysia flight mh-370. why was your vehicle chosen to help with the search and recovery for the malaysia flight our vehicle supports that because it s easily broken down into small modular pieces and easily shipped around the world. reporter: earlier the bluefin-21 spent three weeks searching for the malaysia flight. now another recovery effort that bluefin could help with is under way. would your vehicle be good to use in the air asia crash? it can be employed in that if need be. our vehicle could help map a debris field if it was located
sonar to record what it senses on the ocean floor. when the bluefin surfaces the operator can download the data and see images like these. how do i know if i m looking at a rock or a black box? you have to be a trained sonar analyst. one of the things that s amazing about this technology is over the years the resolution of the system has increased. quite a lot of detail. as you can see right there that s a field of rocks on the left. as the resolution improves and technology gets more efficient and systems get better at differing high quality data interpretive risk goes down. stls an emotional part of what do you absolutely. you never want to be a part of a tragic event. you never want these things to happen in the world. but if we can help in anyway we can i think we should. reporter: so vanessa what part are they going to deploy these auvs. they are not being used right
civilian-based, trained pilot what i m seeing, but that still being said they can wouldn t have been able to do anything to evade it do you want to see the regulatory system changed now in terms of regulating global aviation? do you want to see changes made in the wake of this? you know, i mean, any time we have an accident, unfortunately, we still use the adage, tombstone technology, and now, we have got a new threat that we have got to deal. now, we ve lost lives and, yes, indeed, of course, there s something that now we have to consider. in our own flying at this point. i appreciate the expertise. thank you so much. just ahead here in the newsroom, secretary of state john kerry said that the plane disaster is a moment of truth for russian president vladimir putin. will this incident though push u.s./russian relations back to the cold war era levels? has it already? we will discuss that next. really. so our business can be on at&t s network for $175 dollars a month?
