I know that the inspector in charge at Bristol airport is an aviation enthusiast and a private pilot of long standing
He's one of only a few left. Although it is a generalisation, the fundamental problem these days is that the majority of airport managers/directors/CEOs have no passion for aviation and as such cannot comprehend that a large proportion of the population do - including many who are active in the field. They are so indifferent and short-sighted that they fail to understand that the elimination of good viewing/photographic facilities does not enhance security, it actually achieves quite the opposite. Bravo to the attitudes of Manchester and Bristol. Heathrow and Gatwick, wake up!
