Pelo que eu li, a idéia de Superman ser capaz de voar, ao invés de apenas pular, foi inventada pelos aqui . Essa idéia só foi mais tarde introduzida nos quadrinhos - alguém em esta página The Great Superman Book , de Michael Fleisher, dizendo:
In the early years of his super-heroic career, Superman was not endowed with the power of flight. Although he possessed superhuman speed, he moved from place to place by running or by executing gigantic leaps. Month by month, however, Superman’s running speed increased, along with the complexity of the aerial maneuvers he was able to perform once he had left the ground. The transition from leaping to actual flying was extraordinarily gradual and was punctuated with a great deal of inconsistency. Not until May 1943, in fact, is Superman explicitly referred to as a “being who can fly like a bird” (Act No. 60: Lois Lane-Superwoman!”), and not until later that same year can it be said, without qualification, that Superman actually possesses the power of flight (Act 65, Oct ’43; “The Million-Dollar Marathon!”; and others).
