It might be an interesting sociological exercise to see what the incidence of drunk/obnoxious/psycho air rage incidents are in the wake of the attacks. FWIW I think that airline personnel and passengers are going to have a real short fuse with anyone trying to pull any “air rage” stunts for some time to come and I would venture to say that most of these dramas are going to be snuffed out a lot more quickly than they have been in the past.
