I really hope that doctors don't provide medical advice based on idiocy(or lack of) of ones actions. If she had to undergo emergency surgery in-flight with a coat hanger, I'm really surprised an emergency landing wasn't recommended by the doctor. The origin of her injury should have had zero bearing on it.
If only we would leave more of these decisions to arm-chair bien-pensants, second guessing two seemingly highly competent medical professionals. I am sure the woman in question would also really have appreciated being settled with the likely ruinous debts resulting from a medically needless emergency landing.
