Personally I think that the whole security issue has taken on the same completely OTT and lacking in common sense route as the H&SE.
There are gaping holes in security everywhere but as long as the public face of security is strong armed well then, on the face of it, everything must be ok.
Access on to the apron from the pumps at Blackpool is easy - access to a light aircraft via a flying school at Blackpool is easy but the completely unbalanced security issues raised by the thread originator are simply illogical and no more than a joke even if viewed with token logic.
The problem is of, course, who in public life will stand up and condemn security measures? Just like who will stand up and condemn hi vis vests? OK radically different situations but both involve the peceived safety of human life and it is very difficult to argue against the system which exists to preserve and protect human life.
Aircraft can be taken out with SAM's and individual aircraft can be identified with simple Air band receivers. Very soon all commercial air traffic will be able to be seen and identified on a home PC via the Kinetic SBS receiver. You plug the aerial into your PC or lap top and hey presto Blair Force 1, purple traffic, and all manner of aircraft accurately identified in a real time radar presentation on your own PC c/o Mode S. Of course the general public don't know about these risks and therefore don't worry about them.
