Phoenix Sky Harbor International Airport is a rather busy place, mostly attributable to the Southwest Airlines and US Airways flights that seem to be constantly arriving from every point in the United States and occasionally beyond. If you can find a good spot in the airport's landing pattern, like downtown Tempe or the southern extremes of Papago Park, you can watch a new plane descend almost every minute. The job of an air traffic controller at PHX must be a non-stop one.

I was near the intersection of Priest and Washington when I tracked a Southwest 737 across the sky. It's not quite silhouetted against the sun, but I think it works even so. All part of the charm.
