Air Traffic As Art

A graduate student named Aaron Cobland tracked all flights across the United States on March 20, 2002, using FAA satellite records and imagery. What he produced was an astonishing view of "America painted by planes."

At dawn, planes arrive in the northeast from Europe while the eastern corridor alights. (Image below.) Soon, the entire U.S. is revealed as flights erupt in the midwest and west and traffic starts to and from Asia.
