Aviation
There is an art, or rather a knack, to flying.
The knack lies in learning how to throw yourself at the ground and miss.
Most people fail to miss the ground, and if they are really trying properly, the likelihood is that they will fail to miss it fairly hard.
Clearly, it’s the second point, the missing, which presents the difficulties.
One problem is that you have to miss the ground accidentally. It’s no good deliberately intending to miss the ground because you won’t.
You have to have your attention suddenly distracted by something else when you’re halfway there, so that you are no longer thinking about falling, or about the ground, or about how much it’s going to hurt if you fail to miss it.

Hilarious image of the plane falling apart!
Guy who left the plane (bottom right) might be enjoying himself in free fall – a minute of unpowered flight before getting his celestial wings.
