Superman's flight...
How exactly does Superman fly? I know he is a highly evolved specimen from Krypton, and in his description at the beginning of the first Superman comic, it is said that Kal-El would be able to accomplish great feats such as super strength, invulnerability, so on and so forth. How, though, is he able to fly? If anything, being highly evolved would entail his jumping super high, right? He'd be more comparable to the Juggernaut. He has no aerodynamic body as birds do...it's just like a human's aside from the perks. What gives?
