The dreadful Box Film programme on the accident found an accident investigator who also asked why the up elevator command resulted in a pitch down movement. They also asked the opinion of a PPL expert, also ignorant of the 320`s fby philosophy. I did the translation of the initial report and it appears the elevator acted exactly as it was programmed to. To their great credit, BA had the aircraft back in service shortly afterwards and they had a highly respected and very critical flight safety department.
