Google Map showing aircrafts avoiding UK's ash-filled skies

A volcanic eruption in Iceland is sending ash cloud over to UK which has resulted in airspace over Britain to shutdown.

At Flightradar24.com you can see in realtime on Google Maps, aircrafts clearing the British skies. After several tries I was able to access flightradar24.com, maybe because the traffic to the site which currently might be heavy. (via Techcrunch)

Launched in Sweden in 2007, Flightradar24’s network of hackers and geeks who have an ADS-B receiver has grown to over 100 ADS-B receivers. They receive the information from airplanes with ADS-B and send this information to a server, which then plots it on the map. Only airplanes within the coverage area of the 100 receivers are visible.
