Great photos. The display by the Lynx 'Black Cats' was an extra treat to the action I saw on the track. I have never seen so many helicopters at an aerodrome at one time!! Also Silverstone provides a full ATC service, I am led to believe.
There was some rumour I heard years ago that Sliverstone is actually the busiest aerodrome in the country on Grand Prix day in terms of daily movements and that it even eclipses Heathrow! Whether this is true or not, I'm sure somebody can clarify/correct this for me.
