Given that a load of the media hype is still, as always, completely over the top, can we remember a few salient points.... as a fully qualified and trained pilot-in-command (PIC) (fancy name for captain of the aircraft, co-pilot is referred to as pilot-non-flying, (PNF)), she/they would have completed many hours of simulator training and testing that would certainly have covered these points ...
1. Single engine failure procedures and landings
2. Emergency decompression and emergency descents
3. Structural damage procedures and operations
4. Seriously ill/injured passenger procedures
Given the published recordings of her conversations with Air Traffic, it would appear that all that training "kicked in" and she coped with a very unpleasant situation in the manner for which she has been trained.
She is NOT (IMHO) a "hero" .. just a damned good pilot who did what hours of training had equipped her for, in a calm and methodical fashion. Given her history as a Combat Fast Jet pilot, I'm not in the least surprised.
The girl done good, but she did what was expected of her, that is why she sits there as PIC .....
