Why Superman Can Fly

The son of Krypton is no doubt the most prominent superhero of all time.
One of his special traits is that he is able to fly!
Not many superheroes can do that, especially the earlier ones.

Well, it turns out that he hasn’t been able to fly all the time. There was a moment when all he could do was jumping over buildings. And no, I’m not talking about the time when he hasn’t worn his costume (being the young Clark Kent).  I’m talking about the time he HAS worn it and been called Superman.

In the earliest comics, Superman was not all that powerful. He was only faster than a train, as strong as all you need to lift a car, and he couldn’t fly.
All he did was jumping over distant buildings.
When the comic was going to be made into a cartoon film, his jumping ability proved to be a problem.
There was too much production cost to draw a man jumping over different buildings all the time.
So, naturally…
He was made able to fly.

Regardless of the actual reason, I still love the idea that he can fly. It would be un-cool to see a man with a large piece of cloth on his back jumping around mercilessly.
