Ole Buttermilk Sky

I love flying. Even though I work with aircraft all the time, I'm still amazed that they are able to fly. I mean, I know all the physics behind it and all but still, sometimes I can't believe we managed to make huge and very complicated pieces of machinery fly.

"Ole buttermilk sky
I'm keeping my eye peeled on you
What's the good word tonight
Are you going to be mellow tonight?"
