In my heart o hearts I hope and believe that it was FADEC or avionics loading failure. However, one has to consider a scenario (one of many)that may fit the facts as recorded by the BOI. In the eyes of the revered audience in the back of the cab the crew had, (but really had'nt) "SF/Gulf War" background. They may have felt honour bound to prove their capabilities to perform in such a manner for these not uninfluential pax, as indeed many of us have in the past. The majority of us across all types havepushed weather limits before to get the job done or impress!
As I said, it's another scenario to fit the facts.
