Henra,
Hadn't they lost control surely more could have survived
I'm not so sure about that. The more I look at it, the more I'm convinced that the last few seconds of that flight were pure serendipity. They may well have been looking at a nice big fat field the other side of the river as their preferred forced landing location, when all of a sudden, the #2 fires back into life by unfeathering and flips them over. There's little to suggest (to me, at least) from their flight path that they were
aiming for a river ditching as their solution - but impacting the opposite bank would perhaps have been far more likely had it not happened.
Since you were much more measured in that last post, please allow me to retract the implied
ad hominem from my last response... I have to be honest, I'm a little prickly (and disappointed) at the massed hordes seemingly intent on apportioning crew blame before all facts are known...
