Thanks for your reply cloudwarrior and info.Next time your there try the Iveco place but dont say I give you this spot to try but near the entrance way if you walk straight on toward the airfield perimeter fence you can get good side on views.
At the entrance way if you look to the right before doing this there is the reception office area so they can only say” yeh or neh” but nothing ventured nothing gained.I did hear from someone that when they have a families day they do let folk in to have a look from this area but dont take my word as law as you know what rumours can be like.Good luck anyway and let me know the outcome if you do give it a go.:)cheers..John.B
