The problem and solution has been known for several months.
Yeah. I guess my point is that the problem may have been more impactive than they thought, and the solution less effective than they thought.
FWIW, I’m still in the “it’s probably pilot error” camp on this, but I am getting the feeling this plane is harder to fly (in some conditions) than other aircraft. And it may take special training/certification, exactly what Boeing was trying to avoid.
No need for that kind of snark for a fellow Freeper tho.
