It is quite incredible how far off track you guys have become.
The design interface played no more of a role in AF447 as did Boeings design interface in NW6231 back in 1974.
Everything posted in the previous two posts as in BOAC's silly slip up highlights nothing more than YOUR personal refusal to get in tune with the aircraft. The proof is that your clarion calls for change would have us believe that stick shakers and feedback and no electronic software would have resulted in a different outcome.
WAKE UP CALL: Aeroperu, Birgenair, NW 6231. Thats 3 Boeings so why haven't you called for major design changes on them?
I quote again the President of the Flight Safety Foundation
"This should have resulted in a log entry"
