The British Airspace before the Volcanic Eruption
More than 7,500 commercial aircraft crowd into Britains skies, carrying more than 500,000 passengers from every corner of this little green planet, these are the GPS traces of every single plane entering the British airspace, they follow their own secret motorway system, strictly laid out routes that run north, south up and down the country, and out over Europe and the Atlantic. Dotted around the country there are stacking systems, round abouts in the sky where they circle waiting to land at one of the 7 major airports. The gaps seen are areas closed off to air traffic because far below there are secret military instillations or even high security prisons.
