TheShadow;
PJ2 may be one of these consultants for all I know.
No, I'm a retired, non-interested "non-aligned" airline pilot who flew the airplane. I have no agenda other than understanding what happened, and once in a while, (less often now), offer thoughts from my knowledge and experience with the airplane, all of which may or may not be helpful or relevant to such understanding. From my pov as an airline pilot with 35 years in, I think the airplane is exceptionally well-designed but it is still an airplane.
