Really!!! Are you including all the MOD civil servants in that number?
On the subject of Year Books and Air Clues etc, I think its inevitable that they just cannot compete with things printed during the days of the Cold War. So many aircraft, sqns and personnel with the capacity to provide stories that could actually be talked about. Nowadays, we are so stretched, with so few of the above and so many live operations that cannot be opened up to Joe Public, its no wonder editors struggle to provide decent copy. Hey Ho!
