"Or perhaps like the HEMS unit not far from you at E. Mids, it's to identify the paramedics who think they are better than the land crews they attend incidents with!"
That is the very attitude that the HEMS Paramedics avoid like the plague. Are you by any chance failed aircrew?? All the paramedics do a brilliant job, regardless of their mode of tranport. You will find that most of the aircrew involved work on the road as a part of the rostering.
I suggest you wake up, sniff the coffee and get yourself a life!!!
