And, again, nobody can say why. And that is why nobody can start making wild accusations about pilot error.
One last thought. Has anyone here even seen Andy's display plan? Does anyone know what manoeuvre he was supposed to be performing. I know what we think it was, but who knows for sure and who knows what may have happened during the manoeuvre? More supposition.
Oh, and one more thing. Any unproven accusation about pilot error is always inappropriate. In this case based purely on the supposed expert opinion of someone else without all the facts available - That, by the way, is pretty much everybody at the moment.
