Britain’s National Air Traffic Services (NATS) are responsible for handling much of the air traffic control in Great Britain and elsewhere. The most business airports are around London.

NATS handles over 2 million flights in UK airspace every year. Of those, over 1.2 million arrive at or depart from one of the five main London airports. That’s over 3,000 flights every day using just six runways. And 99.8% of flights experience no ATC related delay.

The organization created a really cool visualization to make understand how their typical day looks like. The video show ever flight starting or finishing in London over the course of 24 hours.  Each airport gets its own colour. The effect is amazing:
