Speed has nothing to do with stalling, and >I don't think you can say an aircraft has stalled just because the wings >are producing no lift or it has stopped mid air. The definition of stall: "A condition in which an aircraft or airfoil experiences an interruption of airflow resulting in loss of lift and a tendency to drop" If you ask me, being at a dead standstill seems to indicate an interruption of airflow, and a tendency to drop. I think it is actually possible to stall an older aircraft by going too fast. The air rides down the front of the wings, so that you lose the airfoil effect, but you're moving very fast. Like you said, the angle of attack has a large effect. However, an aircraft could be said to have stalled if it has hit a brick wall and still has wings. Just my thoughts...
