P.S. I've been flying for a few years (since '08) and for a while I've been able to "judge" my airspeed with how mushy and responsive the controls are and avoid stalls and snaps while turning and flying. I suppose having a 3D background helps.
You make some good points here. The phenomenon occurs near the ground, when we are thinking about landing, and we are over-controlling the plane because there is limited room to land. At that point we are less than one mistake high, and the winds are usually more turbulent near the ground.

I know that feeling where the controls feel mushy and the plane is starting to look like a lead weight. If it is close to the ground, it is already too late by the time I notice it. I can see how 3D experience would be a benefit, because it allows you to push that stall envelope and still have the power to defy gravity.
