Lenz,

No problem, I've been meaning to post there myself with this pic. M. Grambling, if you ever get a chance to watch modern jets fly at low speeds say on landing or in this high alpha mode you will see the elevator moving quite rapidly up and down. Modern flight control systems and actuators are making constant corrections. I'd say the pic just happen to be snapped with the elevator in that position. I've seen these elevators (actually ailevators on jets) move up and down as much as 30 degrees rapidly.
