Computer Security FAIL

Adding to the Navy ship that dissolves in salt water and the government radios that can be easily jammed or tracked, now it seems that the controllers for Air Force Predator and Reaper drones have been infected with a virus that they can’t get rid of. It sounds like this was primarily due to the system operators not taking appropriate precautions rather than a failure of the equipment itself. However, the fact that the link between the drone and the ground controller is not encrypted is a design screw-up. So once again, I have to ask where did these engineers get their degrees? At a clown college?
