They probably already have, but are not telling us because it would have global ramifications.............I R A N..........Hacked Drone..................sound familiar?
Imagine if the world found out that ALL 777 or similar aircraft could be electronically hijacked with no warning........
I know I read somewhere recently about another 777 that acted odd; and the pilot described it as if it was not responding to his controls, was instead trying to do it's own (someone else's?) thing...it was a strange incident and the thought that it might have been hacked crossed my mind when I read it. One of those moments when I shrugged and told myself I was getting way too paranoid.
