For many, the word "apprentice" brings to mind the whimsical scene from Disney's Fantasia where Mickey Mouse, the poor peon to the sorcerer, creates a mess of his master's workspace when the brooms and buckets come to life in a magical musical number. The helicopter apprenticeship at Stanford University seems to contain some of the same elements of unrealism, as helicopters learn to fly and execute complex airborne tricks without a human pilot in the cockpit. In this case, however, there is science behind the magic.
