Just "guessing" here, yet I'd think you almost wound NOT want that unless you could set it up so both the pilot and bombadier had control of the plane. Though I'd guess there were many planes where the bombadier shouted "left, left, left...hold that course" to the pilot, there were others (maybe just heavies) where the bombadier took control of the plane through the run like a co-co-pilots seat.

Not sure which aircraft that would apply to......Yet what happens when it's just you on an aircraft, or the other guy(s) refuse to make the run from either of those two seats.

All just things to consider.
