The last two hours of voice transmission in the cockpit. the flight data recorder records a lot further back than that. the next step will be sending down a r.o.v., a robotic submersible that this is a work class rov. it is industrial strength if you like. able to bring back quite large pieces to the surface. if you get the black boxes, you don t usually need to go back too much further with forensic examinations. what if they don t reveal everything? like i said, this flight flew on for more hours than usually, i guess the cockpit voice recorder usually records. david, correct me if i am wrong here, is there is a possibility that the black boxes won t have all of the data on it and what if it doesn t? what will they do then? i have been hesitant to bring this up previously. when we talk about the flight
Great rush. then we would need to bring in more equipment, an rov. that would go down to retreat the black boxes, all large pieces of wreckage for forensic examination. captain darby, these are hopeful scenarios. these are ifs, if the pulses can be redetected, if the pulses turn out to be the black boxes. a lot of pope here. it is. if it a true ping, it s well founded. they have been extremely lucky to find out or had information others didn t have. somehow we took hundreds of thousands of square miles and brought it down to a pinpoint as the gentleman said. i m excited if it s a ping. if not, we re back to where we started. all this hope shrouded by scepticism. hearing from nic robertson, out
Though these boxes may be in the general vicinity, lets talk about the depth of three miles potentially in this area. we heard our jennifer gray make comparisons of that, distance of 20 eiffel towers. what kind of equipment can be brought in, the time line to bring in and salvage explore beneath the surface? that s a very good question. if this is verified as a pinger noise, then really we ve hit the jackpot and we re able to stick a pin and say this is the spot. the next step is to map the sea floor, probably first by sonar which the echo is equipped with and side scan sonar which would provide imagery of any wreckage on the sea floor. after that, really, the clock stops in the scene there s not a
Right now a british navy survey ship in the area of the indian ocean where a chinese ship detected underwater signals. this could be a lead for flight 370. there s serious concern about the equipment that detected the pulses. here is cnn s report. reporter: we now know more about the equipment used when the pinging sound was reportedly detected. we spoke to the company that makes it. they tell us divers can use it or it can be used hand-held from the surface like the chinese are doing in this video. clearly this hydrophone does not go as deep as the tow pinger. remember, the tow pinger is what crews are using on board australia ship ocean shield.
Move that quickly. around noon. they are still contemplating in the press release what they were going to do and finally decided to answer this. as i mentioned earlier, i don t think they can ignore it whether they want to or not, this was broadcast in china as the finding of the airplane. if the echo gets there and it finds nothing from the equipment they are still going to have to go to the bottom with the submersibles and do more. i don t think they can sale away and say we didn t find anything, the chinese were wrong. where would these submersib e submersibles come from, if there s duplication of the signal, a lot of equipment has to be brought in. we re talking about not just hours more but days more if not weeks. not exactly my specialty but certainly this is not
