Unless they are on a plane that flies into a building, or gets blown up after a hijack, or are on a bus when the suicide bomber blows themself up? Strangely I would have thought (silly me must be imagining it) that aircrew were very much in the front line, but then again I just get my information from the real world, so am obvioulsy well out of date. Chris, as an insurance type perhaps you could offer me some low cost insurance for real world risks, it must be cheaper in yours?
Messy the 'reason' is the change to terrorist get-out clauses by insurance companies post 9/11 and the change to having terrorist incident response capability by FRS since 2003...........not quite a decade, yet.
The new dimension of terrorism we now face is one that provides far more risks to the attending emergency services, the IRA did not target firefighters, the new terrorists will be after anyone and may well cause deaths among rescuers by deliberate action. I hardly think that the pervious risks were of the same magnitude, unless you were from the police or armed forces.
