The trained guards at the front and back of the plane
may be workable. Having weapons on the flight attendants
would just supply an attacker with a weapon.
Clarification: Better security before boarding I
think is the priority. Training the flight attendants to
spot possible problems is a good idea. Which is probably
already done to defuse possible air rage incidents.
As the AM notes, most of the time the guards would be
bored. At lot of the solutions that people are tossing
around will need to be reexamined later when we aren't
hurting as much.
We now return to perl programing already in progress
