Guys, one small sidenote from me:
I am by now receiving questions by PM concerning my previous post here which I cannot possibly answer as actually, I don't have a clue myself; I did not write the message!
As I pointed out, the only thing I did was to copy the original message from the NATO-organisers of the Spottersday. It was originally posted in a different section of the messageboard (Spotting Germany), but I thought it would be more appropiate and get more coverage if cross-posted in the airshownews-section.
I suppose all we can do is wait for the clarification due by the end of the month, as mentioned in their original message. If and when I come across updates, I will again try to cross-post them in the airshownews, but please try not to PM me...
Sorry I could not be of more help, but I'm hoping all will turn out well for everyone (including myself) that's hoping to visit GKN!
