When does Son Goku learn to fly?


In chapter 202 of the DragonBall manga, Goku floats into the air to see where
his child is:

Then when he is travelling along the green scale road, he flies a portion of
the way there. He also flies to assist combatting the Saiyans after his
training with the Lord of the Worlds.

When did Goku learn how to fly, when previously he had only used Kintou for
aerial movement?




The first time we see Goku fly is in Chapter 193, page 10. Krillin, Master
Roshi and Tien actually describe it as the Air Dance. Since the first time he
saw the Air Dance was at the previous tournament, we can conclude that he
learnt in in between the 2nd and 3rd tournament, during his time training with
Kami. [![enter image description

It was never shown, how he learned to fly, so that's pure speculation. The
DragonBall-Wiki has a possible explanation:

> Goku likely learned how to fly from Kami during his long training at Kami's
> Lookout, as he was unable to do so before and demonstrated his abilities to
> conclude his World Martial Arts Tournament fight with Piccolo.
