The decision to go/ no go must be based on sound aviation decision making/ judgement. The nature of the patient's medical condition must not influence a pilot's decision. In fact, the aircrew must not be advised of the patient's condition during their acceptance or declination of a flight.
DK, that's an excellent point. I think its a good mantra for SAR as well, at least to an extent. Long and interesting discussion, but a bit off topic. Maybe another time.
