Thanks for the snaps REF. I did creep up to the tower recently - it's enough to make you sceam & I nearly did. I will have a go at the bat thing. Where they came from is a mystery but they do suit the purpose of keeping people out. Having said that, travellers damaged the roof some years ago I'm told & actually had fires there.
This is the link to my Flight Sim. screenshots. There are 45 or so aircraft flying in & out. http://www.flickr.com/photos/2719341...7624597362588/
I've made 25 so far & am taking shots for a flickr section My WW2 Airfields or similar.
Cheers for now.
