He believed it would never have happened if he was at the controls, as he was familiar with foggy conditions in Cork
Did he really say this?
Fog is fog, at Cork or anywhere else, either you have the right conditions to land or you don't, to say because he was familiar with the fog at Cork and therefore the outcome would have been different if he had been flying implies to me me that he thought he could have landed safely when the other crew couldn't. This to my mind doesn't make any sense.
