erm... you know that the atmosphere more or less rotates with the earth? Wind is by definition a difference between the velocity of the air and the velocity of the surface of the earth. For convenience, the earth is used as a fixed frame of reference. If you want to bring relativity into it, i'm happy to play ball... If you have such a poor understanding of physics, maybe you shouldn't be so condescendingly sarcastic when correcting people on it.

You're wrong. There is no physical connection at all between the cockpit and the control surfaces. EVERYTHING is filtered through a computer. And I have no idea where you got the idea that the computer will automatically "guess" at the correct airspeed in the event of a sensor failure... In a Boeing, the pilot is in command. In an airbus, the pilot must ask politely...
