Oh, my dear, magic indeed. You will find that magic is merely one way to define an unknown scientific machination. I am sure that if simians were to develop some form of aeronautical prowess, then we could determine the cause through experimentation and reason.
Though if you are ever in Las Vegas, I do recommend you seeing one of the talented prestidigitators. There are also large buffets and prostitution if stage shows are not your interest. A fascinating place.
