I feel that if the previous Airbus incident at Moscow had happened to a Boeing, the fact that the pilot was unaware that rudder reversal could result in loss of the fin would have been acted on, and the manufacturers' notification would have been issued shortly afterwards. Boeing is far more pilot oriented that Airbus, which tends to be engineer driven. Airbus non moving throttles, which are almost universally disliked by pilots, are a classic example of this. A comparison of the design philosophies of the B777 and the Airbus fbw series shows many examples of these differing approaches.
