That is very true and we normally only use life flight during rush hour in urban areas, but it is important to remember that Clackamas county, our largest county area wise that has EMS service has no level one trauma centers and only 3 Er's (where I would not allow myself to be taken, by the way) to service more land. Much of this area is classified as frontier and our response time is 4 hours or whenever we make it. In these areas, we tend to activate life flight more often, and also to transfer from other states as the next closest trauma center is 5 hours away to the north, 14 hours to the south, not sure on the east, but we do take several flights in from states to the east of us, and nothing on the west side. We have 2 mountain ranges that are more than an hour from any hospital code three after you make it to The freeway, and several other rural areas that have need of our life flight. We only put them on standby until we have assessed the patient (that is EMS or fire as all of our fire crews are paramedic crews) due to the plethora of false calls where life flight went to a scene where the 911 caller was panicked and said the call was much worse than it was in actuality. It is an imperfect system, but it works in our area, especially since flight craft are only ever about 10 minutes away from any of our urban calls. Again, not perfect, but it works... Also, it puts health care decisions in the hands of *gasp* health care professionals, not Joe public.
