I am only a thick ex-MetMan, but does not the good book say:
9. Only in cases in which there is absolutely no doubt whatsoever should deceased aircrew be found negligent.
QED
I was in St Boniface Church, JHQ Rheindahlen, when the news broke. The shock and loss was very real indeed to several in the congregation, who had friends on board.
To hold the aircrew to blame, given the manifold doubts expressed then and since, flies in the face of natural justice.
