The coordinated team work and shared procedures in a 2 man cockpit make a lot of sense to me. Reading the accident reports usually highlights what they didn't do (and should have done) - and unfortunately didn't get away with it.
Unfortunately it also highlights sometime that a Capt. is a Capt. and even when he is SNAFUing badly, the F/O hasn't the gall, balls, guts or permission to get it right.
Son-in-law is an F/O, and the other day demanded that the Capt. be exchanged for the 3rd & 4th of the days 4 legs. Was done and then of course the diciplinary ... Thank goodness that the cockpit tape was perfect evidence. He was right - but what a way to have to prove it and nearly getting killed and then fired in the process. There has to be a better way - perhaps just computers....
