controls the in-flight entertainment system. this is the system we watch movies on listen to music. he said through that he was able to hack into the control systems for the aircraft. we should say that boeing which is one of the aircraft he said he was able to do this on boeing says there is a separation of the computer systems, that it's not possible. same thing with airbus that he says he's able to do this. airbus said they put spy laws to make sure this doesn't happen. this is an investigation still going. i should say chris roberts has been tweeting in the last couple days after this affidavit was made public and he says that the fbi has taken everything that he said out of context, and he hasn't said anything more about it. >> really quickly, is there a feeling he was blowing a whistle or was this some kind of cat and mouse game or do fbi investigators think there is something else behind this?
