Hacking into the GPS systems of Drones does NOT take a computer coding specialist or anything even close. Its very,very, easy when using "spoofing" techniques to trick thier guidance systems. This lets you take control without having to bypass the codes used by the pilots and the military in general.....the fact that countries around the world are spennding billions on these "drones" is funny....they are computers...thus hackable. Anything is with enough know how on a computer. GPS in general is a piece of cake to get into.
