Actually, there is no pilots union in the military, perhaps fortunately, because they likely would have opposed the creation of un-manned drone aircraft such as the Predator, which has been wildly successful in Middle East operations. Current aircraft have both reconnaissance and air-to-ground attack capabilities. These aircraft are piloted from the ground by ex-fighter pilots, but the next generation will be able to take off and land themselves, obviating the need for even a ground pilot. Wired has a longer article on these cool drones. Beyond the obvious reduction in risk to humans, the drones also have the advantage of being substantially less expensive than human piloted fighter craft -- as little as $15 million apiece, even for the next generation tricked up models.
