Come back east and move in the other direction? that doesn't make any sense. it's just more things in this story as we learn more if there are just more questions and it gets more frustrating. >> how do they know that it was entered into the computer? >> this information was sent down by the plane in those moments leading up to when they lost -- they basically were lost on civilian radar. >> so that would be -- would that be at the 107 acars communication or not? >> yes. from the acars situation it was sent back down. >> acars every 30 minutes it sort of cycles and nothing received at 21:37 fr...

House, do you respond to that, do you think it was someone or some thing? >> i have been contending all along it is still a mechanical issue we haven't determined what it s it just -- i won't rule anything out either, but at this point, it just seems almost impossible, not impossible, but it seems more -- very diabolical for the knowledge that was require even for us as pilots to do what we've apparently seen with regards to disarming the transponder, the acars. it just seems implausible to me. >> all right. so let's go to these 12 minutes, the new data, this information that 12 minutes before...

Of a sudden made a u-turn and got into a very big discussion about what's it doing, why is it behind us? it should be ahead of us. because they had one identifier on their route wrong. >> this is not a subtle system that there could be an -- >> no, they're going to see it, and with this left turn, it would be presented on their pfd. >> one last question for you, greg. that is, i've been -- i've tried to be very small "c" conservative in terms of figuring out what is real data, what's nobknowable, and what is speculation. it's hard to keep things straight because a lot of coverage on this is so...

Wait a minute, they're not going to beijing anymore? >> if they entered the change and entered it in and started acting on the change they should know it if acars was still working, sure. >> right. so keith, what is your prevalent theory? the one that everybody came back around to today was some sort of catastrophic smoke in the cockpit. maybe a tire fire so the pilots put on their masks, they're pulling circuit breakers, i guess, to try to isolate where this electrical fire is coming from which then cascades, shuts down the transponder and the radios. go. what do you think of that? >> well, i...

>> exactly. primary radar lost around 100, 150 miles. after 200 miles, what air traffic controllers rely what called a synthetic air picture. that is built up using bits of information, the first is acars, acars will send inform was to the air line, it will send things like burn rates and fuel rates and all the rest to have but also a gps position much the other way air traffic is worked sought a procedural piece. they will deconflict by biff givening each airlinary specific mack number to fly, different mack number, procedurally separated through that and through altitude. that's wait they bu...
