I think Dee misquoted. Isn't it: "Up in the sky! Is it a bird? Is it a plane? No! It's Superduperman!"
That makes more sense because the guy can't make out WTF it is heading towards him (faster than a speed bullet).
The big question is, imho, why would the ability to jump tall buildings in a single bound be worth noting at all when the subject can fly?
*EDIT*
I have mentioned it before, but be sure to read "Man of Steel, Woman of Kleenex" by Larry Niven.
