Very nice looking site but unfortunately there's a 15 minute delay.

The high speed tracking is quite funny, watching the planes whizzing over the sky 

Especially like the way the designer used icons that are representative of the aircraft so you can tell what the plane is just by looking at the icon.

There are some tracks that appear but don't show an aircraft icon.

I wonder are these military flights?
