The airline confirmed a sudden illness of the first officer and later reported an off duty Boeing 767 captain of another airline volunteered and was accepted to assist for the remainder of the flight.
Yeah how dare he as he is not capable of flying a 747 because he flew a 767. Everyone knows that every airline has different aircraft and no pilot would be capable of transferring his skills to another aircraft.
He also must be breaking the law as he is not trusted to be in the big pointy end
(some the little sarcasm guy doesn't really sum my post up enough).
Reckon it took the Captain all of 10 seconds to suss out whether the guy was a Walt or knew what he was doing at the sharp end.
Captain acted as I would have expected him to, Guest Pilot acted as I would have expected a professional to and reckon both will be dining out on it for a while..........enjoy it as you did the right thing.
