Aircraft landing defined: The art of crashing the plane a gently as posible to avoid damage and be able to fly the plane again.

Okay landing a plane is the hard part. In esense you have to have a feel for it and the plane will give you that feel as what it needs to stop flying that moment that the main gear touches down. For the most part its learned by practice and an instructor can show you better than anyone can tell you here. It's Zen.
