As a post script to this sad incident, I have heard that the Captain has since been exhonerated and returned to flying duties, since the black ice was not visible, nor notamed and even the fire crews could not remain on their feet.
Also hear was that the aircraft is a total loss owing to damage to the spar.
Could someone in the know advise whether this is the case? Potentially very expensive for the AMS airport authorities I reckon? I am glad that the Captain would appear not to have been hauled over the coals. ...Grace of God springs to mind.
