There's a few good flying proverbs:-

"Try to keep your number of landings equal to your number of takeoffs."
"There's old pilots, and there's bold pilots, but there's not many old, bold pilots."
"In the ongoing battle between aircraft and the ground, the ground has yet to lose."
"It's always better to be on the ground and wishing you were in the air, than in the air wishing you were on the ground."

A Mark Knopfler lyric:-

"Sometimes you're the windshield, sometimes you're the bug."

And untold number of Blackadder-isms:-

"[She] goes like the privy door when the plague's in town."
"If I should die, think only this of me - I'll be back to get you!"

Grab.
