Re: And the first step towards Skynet has been taken..
In the event of direct command/control signal loss, degredation or deliberate interference some elements such as basic flight controls & navigation will have to be capable of autonomous operation till the human can be re-inserted back into the loop. From a military viewpoint it would also make sense that the aircraft be able to defend itself during this vulnerable period. It's not a great leap from that to letting it fly the complete mission by itself.
From a military viewpoint, sure. From a computer science viewpoint, it might as well be trying to fly to the moon in a Skoda Octavia. "Not crashing" simply means maintaining the horizon, which is a task given to 1st year computer science students studying computer vision (I still have the code if you are interested). "Autonomously identify and engage enemy combatants" is an altogether different board game.
tl;dr - Its only "not a great leap" if you are completely devoid of engineering experience and think like a an army General.
