I would have though it was fairly obvious that she received appropriate treatment in hospital, and was stabilised and recovered. Good news?
Perhaps you would have felt better if you'd been told she'd died, or maybe that would have meant the diversion wasn't worthwhile either, they may as well have let her die on the 'plane if she was that bad.
The person in charge made a decision, and such decisions are not made lightly, and only after receiving medical advice, that a divert to offload was necessary.
Your posting comes across as very insensitive, to say the least - maybe you didn't mean it that way.
