A few (too) many years since I was in AKT also, but it's a very large base (it was known within the service during it's heyday as "The Big A") and it's peninsula location does afford a certain covert concealment - at least by land
Err - I was orderly officer there in 1986 when a co-ordinated terrorist attack targeted the base in retaliation for assistance to the US F111 sorties. They drove up Ladies Mile to the fence and lobbed 3 RPGs onto the beach (crowded on a Sunday afternoon) and emptied a full mag of AK47 rounds into the car park. The other team had a mortar and walked several rounds across the airfield, fortunately missing anything important.
Amazingly there were only 2 very minor injuries.
More competent terrorists could have caused carnage but I am sure the Station is a bit more secure now.
