It doesn't matter if the aircraft are piloted or pilotless if they can be overridden from the ground.

We have an override from the ground now: scramble the jets and shoot it. The same level of security that results in scrambling the jets can be achieved in overriding the pilot with software.

Testing a security system doesn't compromise the security of its implementation because in production the encryption keys are different.

Um...OK. So are you saying that we should have a completely pilotless system then? Or that there are easier ways to implement an "override" than being able to control the plane from the ground. F-16s, armed flight crews, isolating the flight deck, etc. If so, I agree.

My argument is that implementing a ground based override system is needlessly complex and introduces far more potential problems than it purports to solve.
