A computer simulator for RAF pilots is so complete in every detail of the north Wales landscape it even includes a rude message painted on a forestry worker's van.

Steve Baughn was so annoyed by the noise of low-flying jets that he painted a plain-speaking sign on the roof of his van - P*** Off Biggles.

Now it is one of the landmarks which student pilots come across when they use the new flight simulator at the RAF Valley base on Anglesey.

The state-of-the-art simulator uses detailed satellite pictures of Wales and the van is shown parked next to Mr Baughn's remote cottage near Bala, Gwynedd.

Mr Baughn painted a similar - but now faded - message on a barn 15 years ago.

But the protest only increased noise levels as pilots changed their flight paths to take a look.
