In this case theres two brands you can use. it happened to be turned off or at least the acar system was turned off so there was only handshaking going across. frankly, i dont really know -- >> would the acar system have been able to transmit that information? >> it would if it were turned on. but if you turn the system off, then really there isnt anything to be sent through the data link. so at that point i dont know how they would know that it was preprogrammed somehow into the a contraction a...

Completely eliminate. >> right. >> multilayered. and if you want to completely eliminate it, which in this case seems to be what they did, you would have to get into the bay there. >> now, if you have degraded the level of acars transmissions, you have switched off vhf, you have switched off s.a.t. com, you have switched off the data link, but the satellite will still attempt to connect to the antenna as its been doing at 1:07, 1:37, on a regular sort of bluetooth way, discoverable. the plane is...

There was at least one missed hand shake when i went from the malaysian radar system to the next system. i wonder if i can ask you a question, a lot of view es are sending in tweets now. its jeff russell who asks, why should pilots have the ability to turn a planes communications off? why do commercial airlines need stealth in effect? why is that ability inside the cockpit of the plane, the acars system, the transponder. whats the safety reason or the operational reason for that? >> well, all ap...

Indicate, again, the timeliness of malaysia giving us this information, but its interesting to me that theres one other way you could turn off this equipment and thats by pulling circuit breakers in the cockpit which would require some knowledge of the aircraft, or at least a list of where the circuit breaker identifier lines were to get at them and one would have to know how to do that. thats a very troubling thing that there was this delay. it would tell me that somebody was at, turning this e...

Evidence of what we have it looks like somebody deliberately turned the aircraft off the intended flight path. >> way off the flight path. leah, let me go to you. im very impressed, fighter pilot, and all the work the military has done. there is a series of reports, "the wall street journal," reuters, says it went off course and flew for another four or five hours. there are safety mechanisms within the triple 7 where mechanical data is being sent back all the time through satellite imagery? >> ...

Ground and is on land. well, that didnt go off. and also i wonder where it is. just like everybody else. >> okay. let me turn now to david suse, former faa safety inspector. we dont have the answers here. this is one of the great mysteries in aviation history and gets more mysterious by the day. having said that we have more information than we seem to have had at any stage in this week. if you take the assumption that these pings -- its interesting i thought what jim tillman just said, the ping...

>> okay. let me turn now to david suse, former faa safety inspector. we dont have the answers here. this is one of the great mysteries in aviation history and gets more mysterious by the day. having said that we have more information than we seem to have had at any stage in this week. if you take the assumption that these pings -- its interesting i thought what jim tillman just said, the pings themselves, is that correct? do you know when they are supposed to go off? do they go off when a plane ...

Failure to you or some human development, whether terrorist, hijacking, a pilot suicide desire, something along those lines? >> that sort of human element. the likelihood of a failure like this is extremely remote. the airplane has redundant transponders, multiple means of communication, data link and different kinds of radios. and there was no communication. so the mechanical failure here is probably not likely. >> take us inside the investigation, tom. i know the fbi is already involved, ntsb ...

This airplane has been very reliable in those areas. again, its -- i would put the airplane further down on the list than other things. >> well, lets consider some of them. john ransom, what about this being done intentionally by the pilot, such as happened with egypt air flight 990? >> well, as was mentioned, this was a fairly modern airplane with a bunch of capability to communicate with the outside world. a lot of data from the airplane. for them to all stop at the same time would take the wo...
