Is the acars system. >> that's not something they would typically turn off. my understand that involves pulling circuit breakers which are on the roof of the airplane. you would have to know what you're looking for. that's not something a pilot would typically deal with. >> this model of plane is relatively new. >> 777 came out in 95. a flew on the inaugural commercial flight on united airlines, they were the first customer. they updated, there's a 300 model and 300 e.r. the planes are heavily electric right now. the circuit breakers are key but the transponder is interesting. you asked about ...

None of it would happen under normal circumstances. in addition, sources are telling fox news that a number of scenarios have come forward to believe this thing went in weird ways. i say that because of this. took off in this direction. this is the spot where it lost contact, where the transponders quit going. 12 minutes later, the acars system, it's a communication system, stopped performing. but along the way, as it took what it is this route, nothing you would ever program in, there was still a system on board which is speaking with a satellite company called n mars, it's located in great b...

Systems, specifically the transponder of data flow systems, how complicated is it to turn them off? >> it's very easy to turn them off. you never have to leave the seat in the cockpit. a lot of people have made a big deal about the acars system. you can turn the data portion of the acar system off from the cockpit. you don't have to leave the cockpit. dwroint have to flip circuit breakers. it is evident the data portion of the acars was off yet the satellite was still trying to ping the box, the box on the airplane was responding, it just didn't have any data to provide, so it's apparent that ...

Electrical power. the one that is more telling is a communication system known as acars. for the acars system to be active and still interacting with the satellites but not broadcasting data, to do that requires special knowledge, specialized knowledge. so i think that's one of the first real telltales, one, the airplane did have electrical power on it or the acars system couldn't have been powered and secondarily, the power stream was switched off. so this had to have been done by someone with knowledge. but we need to be very careful about making sure that we stay where the evidence is and n...

If you look at the fact that they didn't communicate on any of the radios, they may have failed or chosen to be unused. we don't know. the transponder ceased to 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 don't 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 d...
