emergency locating transmitters. the technology that s available in the military. as well as for cameras in the cockpit. a recommendation that was made in 1999 when i was chairman of the ntsb. deborah, that s a good point. he talks about those calls and recommendations being made in 99. calls for further technological advances which we know already exist after mh370 went away. do you think this will increase the calls, once again? or do you think we might be closer to having some of those technologies implemented? i think certainly in the hours before the aircraft a was found, the pressure was again mounting for better tracking better surveillance of aircraft. we have the ability to know where aircraft are in real-time and for them to be sending information directly to ground and to other stations about their position, about what s happening. and i think there was a lot of pressure after 370 to make that
the reason i don t think that is because in my investigations when the aircraft breaks up in flight, you have debris spread over miles and miles, and that would be very easy to see, even in the vast area we ve been searching. even across 750 miles, which, you know, people are not familiar with what it takes to search for parts of a missing plane, you are. even across an area that big, you think they would have found something after four days? yes, i definitely do think that they would have. you have to understand there s not only the search with local rescues, but satellites and other things that are working on this. what concerns me most, though, and what s perplexing to me is that 777 has two elts, emergency locating transmitters that are broadcasting. one of them is activated by shock, the other s activated by salt water. neither of those is giving out any kind of signal. satellites are listening for that, all of the local aircraft and boats are listening for that
