Airbus A320/A330/A340 Electrical Flight Controls
The QUANTAS QF72 accident IS a result of the AIRCRAFT'S FLIGHT ENVELOPE MONITOR AND CONTROL COMPUTERS following their programmed instructions, exactly! See "Airbus A320/A330/A340 ELECTRICAL FLIGHT CONTROLS".

From my experience in a pitchup in a Boeing 707 just on top of a building thunderstorm I report the following. Upon entering a strong updraft the swept wing aircraft design is mechanically transitoned into a nose high attitude, depending on the strength of the updraft and the length of the fuselage from the center of gravity to the end of the tail assembly. This mechanical nose high transition does not increase the G loading on the aircraft, as a normal pilot control input would. The aircraft continues, in this attitude, on its projected flight path for two to three minutes (NASA claims a fifteen mile diameter for an updraft). During this time there has been some mechanical lifting by the updraft and now when regaining normal relative wind conditions a return to cruising altitude is resumed.
