Because it's Friday: Those busy London skies

A while back our Friday feature was a visualisation of the skies over the UK every 24 hours, today’s is a more focussed view of the flow of traffic in the skies over London.

Having flown in-to and out-off London several times it always amazes me how many other planes you can see:

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.
