I actually didn't mean to post the response to your post because I realized that the two situations were different as far as the criticisms being leveled, if nothing else. I left and came back later and responded to the other post but the one I had composed was still in the buffer.That was a simple fix, A rudder actuator as I recall. If this indeed is an airframe design issue the fix is going to be way more complicated.
ASIDE: Underscores why it's a good idea not to even write something that you aren't willing to post even when you have no intention of posting it -- I've seen people write scathing, hate-filled crap saying all the things that "they wanted to say" but had no intention of actually saying, until they accidentally hit "Send", that is.
But that's already the way it is.That is unless pilots and passengers are willing to live with the fact it is going to take software to keep the plane in the air (assuming there is an actual software fix for this).
