A BOEING could do Aileron rolls!

Sure. Read my post above. US Airways #427 crashed in Pittsburgh - in similar circumstances, but in that case the pilots did nothing to cause it.

USAir #427 was a Boeing 737-300. The aircraft leveled off at 6,000 and encountered the wake turbulence of a preceding Delta craft. The autopilot was on and the yaw damper functioning. The slight air disturbance caused the rudder shuttle valve to drive the rudder violently into a left yaw to full travel. As any jet airman knows yaw = roll - within a few seconds the aircraft had rolled INVERTED and then 80 degrees NOSE DOWN. Within 10 seconds the aircraft hit the ground going 350 kts killing all aboard instantly. The wreckage was confined to an area the size of the aircraft wingspan. NTSB ruled the cause of the crash a Boeing design flaw, and the rudder shuttle valve manfacturer (third party) also at fault.

Fast forward to 2001. American Airbus aircraft encounters wake turbulence from a prceding aircraft. The aircraft was NOT on autopilot and the First Officer makes a abrupt rudder input to counter act the yaw - with an immediate OPPOSITE rudder input - driving tremendous forces through the entire aircraft.

Now, based upon those 2 stories, which aircaft would you rather fly in - the one that rolls on its back ON ITS OWN and kills everyone, or the one that breaks apart because someone at the controls does not operate it consistent with basic rules of jet airmanship?
