On any given day in July, Europe sees about 30,000 flights in its airspace, each of which needs to be routed to, from, and around other areas.
To give that task a sense of scale, United Kingdom-based National Air Traffic Services has animated every single flight path into a two-minute long time-lapse. The material was collected from U.K. radar data from June 21, 2013 and European flight plan information from July 28, 2013, according to a release that accompanies the clip.
The result is an astounding tribute to the intricate dance directed by air traffic controllers on a daily basis. Corridors to and from North America and around Heathrow, for example, are particularly frenetic.
NATS jokes that, for most people, the "choreography ... is entirely unnoticed - it quite literally goes over their heads."
