I do not think we know at this point who flew the successfull no flap landing. We know that a female pilot, thought to be the Capt, was handling comms and was PNF in Rotterdam and during the first approach and go around at Schiphol. There is no issue with a Capt letting an experienced FO with many hours on type fly a difficult approach. Whoever has flown it, the landing was clearly performed in a very skillful manner and thus by the right person. I do not think the PF/PNF decision is one that deserves criticism.
