Not sure I follow exactly where you're going with that cfi, bit cryptic for this time of morning. Just for the record though, no I don't think that well meaning amateurs (read charity) should need to disguise themselves as a quasi airline. I'm afraid Monday morning quarterbacking, as our trans Pacific cousins say, is a pet hate and trying to overlay AOC's and the associated cr@p over the top of what has never pretended to be anything other than a charity to help rural patients, is the surest way of bringing the whole enterprise to a screeching halt. Safer, oh certainly, after all aircraft that stay on the ground don't crash, but not exactly helpful to a patient out bush.
To put my comment in context, I was not referring to this specific incident, but the Angel flight concept as a whole, hence my use of "most... patients" in my original post. On the face of it the pilot here appears to have worked himself into a tight corner thanks to decisions made earlier in the day - and to have paid the ultimate price for it. Certainly a human factors lesson in there for all of us.
