This photo is not a closeup of your DNA, nor is it the latest work of art at the local gallery. It is in fact, a representation of every single flight in the domestic US airspace over a 24 hour period.
The picture is part of a map built by Aaron Koblin, on display at Wired.com. The portion you see above is of air traffic into Chicago’s 2 airports, and if you look closely, you’ll clearly see planes headed for O’Hare, and those going to Midway.
The map is zoomable and scrollable, and can be sorted by make, model and altitude of the plane. The real time flight data was provided by FlightView. I can highly recommend wasting a couple of minutes of your busy day to play around with the map!
