We are all being extra careful....all the time.
Scare-mongering headlines such as those of Master Green's are playing into the terrorists hands, unwittingly maybe. They depend on publicity, which generates fear, and let's face it, this site is wide open to the media and the lay public. So at least one area of rumour control is in our own hands. Please let's not join in the general hysteria which has lost us so many jobs, maybe permanently.
I feel that MG's contribution is well-meaning, but in my company we are working on max vigilance at all times, and I assume this is the case elsewhere.
Perhaps to accommodate this subject area, we should have a section devoted to Air Terrorism, although I really am not sure that is a good idea. Let's use some common sense chaps, for the sake of all our careers and safety.
