So Capt Kremin
You are saying that "Richard" was in the seat as a Capt under check, and was not on board as a checker himself.
From all the accolades, none denied, "Richard" was at the controls for the handling of this emergency. If he was under check then it is understandable that he was the handling pilot or the PM. If he was not under check, then presumably he kicked the other guy out. Alternatively, he was not in a control seat but is prepared to take all the credit.
Something doesn't add up.
The question remains.
