TheFlyingSquirrel,
Can't speak for every crew but that is not the case where I work, more than me jobs worth, Guv !
I might take a couple of rapid swigs and burn my mouth but we don't sit around finishing a cuppa and the paper on the grounds we can meet the response times because the call is local ! In these days of 'big brother' and particuarly AVLS, there is no hiding.
Apologies for the general thread creep here but on a similair note to the original police based question, in my experience of air ambulance ops (HEMS missions) the time from call to airborne is approx two to four minutes on the EC135 T2, and it only took slightly longer when the unit operated a Bo105.
