I have now come accross a problem with silverstone again.
although i can get the plane to silverstone by selecting "add-on screnery" on airport selection screen, i cannot select this when setting up a flight plan in Flight Sim 2004.
has anyone else flown to and from silverstone on the UK tour???
this is a real pain!!! luckily i noticed the problem before i got to fly the last 2 legs of the tour!!!
EDIT:
All i can think of doing is flying to turweston which is a little west of silverstone.
this screen shot below shows the aircraft sitting on the runway at silverstone, and turweston airport to the west!!!
The loctaion in realtion to turweston is typed in yellow beneath the picture.

What do you guys think?
