Just to clarify something I might have missed reading the report and the 3000+ messages here (yes): there is a clear understanding that flap 25 vs 30 was beneficial. Is there any further official analysis (be it manufacturer, AAIB, etc) of what could have been achieved in those circumstances ?
I'm also somewhat surprised by the little mention in this discussion of what I believe to be the main factor in the relative benign consequences of this accident, namely luck...
