A fellow named Jeb Corliss glides at incredible speed in a sort of flying squirrel suit, probably ballasted by large nuts. No plane, and unlike Jetman no engine, but with video cameras (that in a pinch would serve a purpose similar to a black box).
I can imagine a superhero based on this, provided you could get away with a superhero who looks like a morbidly obese flying squirrel.
