Breaker and pull the fuse. would it really shut it down or alter the display in the cockpit? there is a big question over what that really means. you dont just switch off acars. you do turn off the transponders. there is a big question as to what was happening with acars. if the screen went dead, they should have noticed it. would they have told that to the air traffic controller, probably not. thats the communication with their company. it is just another mystery. it makes things seem more norm...

Airline, and its been in the news conferences. then 1:19, last verbal communication. this is a significant one, wolf. this is where the co pilot, we know its the co pilot. thats been confirmed at a news conference. the co pilot says, "all right, good night." and thats the last verbal communication. go to another press conference during the week. we know 1:21, the transponder. this is the bit that sends the signal out that the name of the plane, the altitude, the direction, the speed, we know tha...

The satellite element of acar is available but not all airlines describe to it because it is expensive. i dont know whether malaysian airlines subscribed to the satellite communication. it appears that maybe at one point, they subscribed to it. the airplane was properly equipped with that capability. it seems to me that currently, they are not subscribing to that satellite communication of acars. >> so, then, hanz, what about the signals or the pings from the cockpit. what are they looking for d...

Electronic handshake. first to richard quest. what do we make of this brand new series of events? >> its important that we stress what we have done here. we have taken known facts from the press conferences and from statements made by officials, and thats how we have come up with this time line. and the reason i say its important that we get -- we understand that, there may still be discrepancies that will come further down the road. but what we have done is, we have listened to the press confer...

From the cockpit. remember the verbal message, "all right, good night." now today airline officials are saying something different. theyre saying they actually really dont know exactly when that acars system went off. and that its possible, it is possible, it was turned off after the good night message. now, is it that mean anything? does it change whether this is terror potential or mechanical potential? again, so many questions. but right now we do know that 26 countries have skin in this game...

Off position. that is real easy to turn off. the acars on this airplane you can never turn off that box itself because this box is continuously energized and why we have the ping after we lost the data. its the data part that was disabled. and it takes a series of key strokes on an information system and a key pad to actually take the data system down. somebody would have to have a high level of knowledge of how to do that because that is not something that a lot of pilots would know, even under...

Boeing 747. they are focusing on who was on board the plane. finally, more than a week after flight 370 vanished, malaysian plane closed officers searched the homes of both pilots, 27-year-old fariq habdul amid. he said, all right, good night and uttered the last words. >> in this investigations indicated it was the co-pilot spoke the last time it was recorded on twist. >> the interesting twist, a full 12 minutes before hamids final words, one of the planes acars, commune systems are shut off. t...

Aviation expert as well joining us from tampa. is it conceivable there were no other satellites over that southern region and no way to triangleate? >> i think the thing to realize, the acars system is looking for a specific network, like a cellular phone network. it is sending out that its available for data to upload or download, except -- and this is probably one of the most important bits of evidence we have right now, is that the data stream to the acars unit had been shut off. that require...

That system went dark. so did he say good night before or after the acars system went dark? we dont know. we do know that that last message good night came before the transponders were turned off. if you are confused by all of this at home, you arent the only ones as we try to dissect exactly what was said, when it was said, by whom. it really has been inconsistent from time to time. the data and the information coming out of that part of the world. >> nbcs tom costello, thank you. >> lets take ...

Acars. it measures information about the pilots performance and sends information via satellite. its due to transmit again at 1:37 a.m. but never does. 1:19 a.m., someone inside the cockpit, believed to be the co-pilot, provides the last verbal communication with air traffic controllers. his last words "all right, good night." its a common good-bye to controllers after being handed off. at 12:1 a.m., the transponderer which identifies the plane to civilian radar goes off, critical information li...
