When did Superman "learn" to fly?

Question

The original Superman could not fly. Only leap far (1/8th mile). Then somewhere along the way, Superman actually began to fly. What year or what issue of Action Comics did Superman "learn" to fly?

Answer 1

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 length of his leaps and 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 is Superman explicitly referred to as a "being who can fly like a bird" and not until later that same year can it be said, without qualification, that Superman actually possesses the power of flight.

By 1945, Superman is able to fly from Metropolis to Burma in the wink of an eye. "Light travels 186,000 miles a second, but has nothing on Superman," notes the text, "who finds himself hovering over the jungles of Burma in the wink of an eye!"

Answer 2
