"OK, Feather no3 pull the fire extinguisher, 1%2 to 100%, 4&5 to max power, 6,7 and 8 to max power, 9&10 to 100%" Cue blur of hands from the right hand seat and the F/E. Magic stuff!
B-36 Flight Engineers earned their pay in those days. Have a look at the F/E's engine panel - 12-across x 5-down, that's 60 dials at least to watch.
And think of the check-list and engine start sequence - six of these massive prop jobs plus four jets to get turning and burning before they're up-up and away.
