Flight Radar 24 now with aircraft view...

I like FlightRadar 24 and used it at the time of the Eyjafjallajokull eruption to show how the airspace cleared as the ash cloud spread.
If you visit the site you can see the aircraft currently in the air over several parts of the world, including UK airspace.

However, there is also a new feature at the bottom of the left hand column. This enables you, via Google Earth plugin, to 'see' the plane flying over the landscape that is beneath it as shown on Google Earth.....

Nice...

Thanks to the Google Earth Blog for the tipoff to this new feature...
