I am not sure that you could, even in principle, “hijack” a drone by spoofing GPS. You could confuse it, yes. Military GPS have antispoofing and antijam capabilities and I doubt that you could spoof them for anything like a thousand bucks. A truly robust navigation system would have inertial navigation as a fall back, and could either continue its mission or RTB when faced with interruption of the GPS signal.
I have no doubts a drone can be hijacked, necessity is the mother of invention.
It was a necessity to hijack a drone, some very smart people did so.
Now if only we had the same smartness across America to bring down Obamacaretax.
The problem with your theory is that it didn’t know it was being spoofed to begin with. Now it will take years of research, endless government grants and how many acts of Congress to find out how they did it before they can actually be allowed to fix it. Re; the government study of the study to study the studies on the validity of studies? Reading the original story, they were able to totally take over the thing.

They are not going to say how they really hacked it in a public article and you can expect some misinformation. But we know they can be hacked and controlled.
