Hi Crush- I'm curious what the book will be about. Meanwhile:

The Earth's atmosphere has no definite top. The air just keeps getting thinner as you go up. For each mile up you go, the density falls to about 80% of what it was before. (That's why curveballs don't curve as much in Denver as they do in cities at lower altitudes.)
