Much of what KSmedic says is true. I flew two years in MT, loved it until our base closed. Depending on who you fly for it can be a very different experience (see politics). My experience was about 6 years ED with some ICU mixed in. Most of my time was in a Level 2 inner city trauma center, good mix of critical care. Experience as charge is definitely a plus. Not sure of the average career length for flight nurses but I could see it being very short or very long depending on whether you love or hate it.
