Hey Jerry:
Many years ago a friend of mine and I were flying to Colorado. During the flight our conversation found its way to a discussion of the "jet stream". My friend explained to me that the jet stream was a result of jets flying across the country. I thought he was joking, he wasn't! We got into a big back and forth over it. We finally made a bet as to what the jet stream was. At the end of the flight we agreed to have the pilot decide if the jets caused the jet stream or if it just existed naturally as I claimed.

The pilot (United) sided with my friend, that's right, the jet stream is the result of planes flying back and forth across the country.
