his conversations with the FBI lasted for hours, and he later claimed the statements in the warrant were taken out of context. Years ago he built a small "lab" with some IFE parts bought off ebay etc which he then "hacked". As far as I understand the "hacking" of his lab setup (not an aircraft) was limited to some eavesdropping. My guess is his recent references to IFE hacking referred to his lab setup on the ground, and he didnt touch anything on the flight in question. The FBI warrant is probably useless to understand what happened, it was written only to provide a reason for searching his electronics, not for anything else. For some reason he made a stupid "joke" on twitter about his hacking, the equivalent of the equally stupid "I have a bomb". This alone suggests to me he is a nutcase. That's all there is to see here.
