IME, most of the med crews don't want to go as often as I do. They're all former ground medics and ER nurses, and they fully realize that people die, and they don't want to die in a helicopter. I've never had any issues at all from the med crews about turning down flights, but I have aborted a couple of flights that I considered rather routine when the med crew decided the weather was too bad. Our med crews simply don't get rabid about saving lives. Ambulances take a lot longer, but the patient's car wreck isn't our fault, and we aren't going to die to get them to a trauma center a little quicker. The only medical personnel I've met who are really gung-ho about saving lives are newbies, and we don't hire any of those.
