Tdracer. If a Kc135 guy told you anything about a flight engineer he didn't know what he was talking about. I am an old Kc135 guy and we didn't have one. The copilot could dump fuel very quickly though. The check list was: Open the line valve to the boom, close another valve I don't remember the name of, open the dump switch and turn on the refueling pumps. Takes ten times longer to type it than do it. We could and did dump at 6000 lbs a minute. I had an engine blow up at rotation one time and we were dumping by the time the gear was up and locked.
