In the mighty V the 1st Pilot was the captain with the casting vote but 'operational control' moved around the crew stations depending on the stage of the mission.
'twas a foolish man that did not follow the guidance experts advice especially as the pilots only controlled the ILS and the V/UHF radios and even there the AEO had a vote.
I have flown with one pillock who was captain and acted the part. The same part as Orson Welles portrayed on the good ship Bounty and it didn't half show!
