BEA had a thought (an aberation?) in the Sixties that the Captain of the Vanguard should sit on the jump seat and the two First Officers should fly the thing (make it so, Number One!!). I can perhaps understand why a Nimrod or such should perhaps have a mission specialist as the Captain, but a transport? What's the point.
Having said that, I may be missing something here but as a non-military flyer, whoever the "Captain" may be: no controls, no say I'm afraid.
