Spain - October 21st, 2010

The white lines radiating out over northwestern Spain are condensation trails (or contrails) – rows of clouds that form when water molecules clings to airplane exhaust.

The airplanes appear to have been travelling to and from cities in Galicia such as A Coruña, visible as a grey area by the coast on the left side of the image, and Santiago de Compostela, further inland.
