In this fantastic capture by Andrew Choy we see the San Francisco International Airport (SFO) at night. The photo was taken from a cessna plane on November 16, 2005. It was a finalist for the Wikimedia Commons Picture of the Year in 2006.

SFO is the largest airport in the San Francisco Bay Area and the second busiest airport in California after Los Angeles International Airport. In 2009 San Francisco International Airport was the tenth busiest in the United States and the twentieth largest airport in the world by passenger count. [Source]
