"Not sure I'd agree with you there sparky... if the THS had departed the scene, the next thing that happens is a very rapid nose down pitch rate develops, usually fast enough to achieve negative g loads that result in failure of the main wings in downward bending overload." ???? Where had it been suggested by anyone that the THS had separated the aircraft? That is bizarre...Separation of Vertical Stabiliser/Rudder, as in JAL Mt Fuji, or AA 587, or UAL232...yes..... Once Stalled and in an extreme "mush" (nose up, high angle of attack) aft stick may have been a temporary solution to total loss of control... one doesn't want to entertain that a pilot would see a high descent rate and pull, if it was established in a Stall, and he knew it. Bear in mind that the Airbus does not necessarily drop its nose on Stall entry.Shake, yes, but it was designed to be longitudinally stable. If the Stall was entered, and became established in a reasonably stable mush, that would explain how they missed Stall entry...​​​​​​​Fact is, the mushed Stall regime might have been the purposeful work of the A340 test ship. The test crew, finding themselves in 447's established descent profile, could not get the Nose Down, and recovered only after accepting a very unknown and bizarre attitude and out of control platform... ​​​​​​​and they knew what to expect... ​​​​​​​With respect, Will ​​​​​​​
