In an article on The Guardians website, they are once again starting the rumor of unmanned aircraft being the only option going forward. Haven't these people seen 'Stealth'!
Personally I can't see this happening anytime soon, especially not in the US where pilots are such revered people (TopGun any0ne!). I do agree that more and more unmanned drones, stand-off weapons, and loitering weapons will be circling overhead, but the military is still very much obsessed with the human-in-the-loop who has to be the one to press the trigger. After all, if an unmanned vehicle (of any kind) kills someone, who is responsible?
