It has to be said though that in modern airports worldwide the incidence of terrorist related activity is remarkably low. When was the last terrorist related attack on a plane? The Russian A321 from Sharm? More people have died since from pilot error/fatigue. So whilst we all find security a pain and the personnel sometimes rude and brainless, the system has worked, despite stupidity from the managers. It would be nicer if the system was more efficient, more flexible and more user friendly but ultimately it still needs to work for the lowest cost possible.
