As ManaAdaSystem stated in his post #57, the ailerons and elevators on the DC-9 were operated by tabs so they could be hanging anywhere on the ground.
I flew the Short Belfast for many years and all of our control surfaces were controlled by servo tabs. So, when we took the control locks out, the rudder would normally follow whatever the surface wind was doing, both ailerons normally fell down and the elevators could be anywhere.
This used to cause all sorts of calls from the folks outside. On one occasion I was told several times by the aircraft behind me that both of my ailerons were hanging down. "Thank you" said I. "Are you going to go flying like that"? "Indeed we are" said I. Silence from behind.
All surfaces would normally streamline at 90 knots on take-off.
