Makes it sound like theyre incriminating but they arent. lets not forget that. and really, frankly, nothing can be ruled out now. most every scenario you come up with you can run it through. some of the more plausible than others. frankly, the crew being responsible for this is a very plausible scenario but one of many that are still possible. >> les abend, you are the pilot here. you flew 777s. paint for me a picture where if the pilot, as some people suspect, took this plane off for whatever r...

Back into the e and e, the electronics and engineering compartment thats eight feet behind the cockpit and down below the galley. and basically vacate the cockpit. the evidence is such that the acars system was being pinged by the satellite. so he would have had to disable that, too. it just seems so implausible to me. >> you must be talking to pilots all the time about this. im talking to random people in the street about this. everyones obsessed with it for one reason, the mystery remains a my...

Help investigators here? >> were talking about an investigation that has been over 17 days, with no conclusive leads. so, the analysis that the inmarsat guys are doing, that effectively is the interface between the satellite and the acars system. they use that to provide altitude and speed when the acars system is switched on. and that gives information back to the airline. so, its a lot of space, 10 million square miles. so, what theyve been doing in terms of trying to narrow it

Microphone. this is the type of device are going to be using either towed behind a boat in long tails or in order to listen for that underwater pinger. >> how far can it hear? how wide? >> only about five miles. >> so this is how youre trying to find the basic area of where any flat data recorder might be. >> exactly. you need to find the wreck site. >> so if we go from there, lets take a look at the sonar. because the sonar is what youre going to do if you get closer or if that battery dice on ...

Special projects at the woods hull ocean graphic institution. richard, lets talk about this partial handshake. up until today, everybody believed this last communication occurred what, at 8:11 a.m. now it seems there was another at least attempt to communicate later on, a few minutes later. >> right. and if you read what they say about that partial handshake in the inmarsat report that was released today, inmarsat basically said they couldnt say what it was. they couldnt say whether anything rea...

How, well have views on that. but how or why this half ping is relevant. but if they can prove the integrity of that half ping, then it adds one more if you like dot in the chain and you start to now know a little bit more about where the plane went down. because youre no longer -- youve got another point of reference. and you can coordinate that with how much fuel there was and what point you believe the plane would have been in. >> let me say its great to have you back on cnn though not under ...

Aircraft, it cannot only go through the acars system, but it can go directly. so this indicates to me something happened. electrical change, the engines had come offline. >> jeff wise, this make sense to you, something at the end there, that it was trying to communicate with the satellite? >> were really waiting for more information from inmarsat. i agree this is exciting news, not only for that partial ping, but we were given a lot more data about what transpired between the aircraft and the sa...

After 1:07 the acars system would have triggered the same tee vi device to communicate. >> more than seven hours between the last acars and then this final communication, or attempted communication. seven hours. that mystery what was going on for those seven hours in that aircraft. david gallo, how optimistic are you at this point? you co-led the search for air france flight 447. you confirmed debris after a couple of days, a few days. started to retrieve debris on day five. still took five year...

Their rights are and what is in the cargo holds of the planes. passengers as of now have no right to know what is in the cargo hold of the plane they are flying. they cant ask about the acars system on board the aircraft, correct? >> thats right. they have no way to find out, no way to ask. its difficult for them to get information about how their airline stacks up against others. all those questions about a carrier that would help you judge whether you want to fly on that carrier and whether it...

Function shortly after the last communication. it could have experienced an electrical problem. the component could have failed or it could have been switched off. we dont know. but what we do know is that the data link system known as acars was stopped from transmitting data, but the unit itself continued to talk to the satellites. that takes specialized knowledge and it takes some deliberate key strokes into the computer system to disable its ability to transmit data. thats a deliberate act by...
