I run my engines in on a test stand on grass for this reason. Landings are mandatory. God meant man to fly, he'd have given him more money. It's better to be down here wishing you were up there, than up there wishing you were down here. Want proof make it stop, then watch the pilot break into a sweat.
Speed is life, altitude is life insurance.
No one has ever collided with the sky. It's best to keep the pointed end going forward as much as possible. But very few know the definition of a great landing. It is one after which you can use the airplane another time. Always remember, you fly an airplane with your head, not your hands.
