Glad you asked. I mean no disrespect, but you are overlooking the obvious. In the absence of suitable technical data, you call me to task because you don't believe in something that I do. (Ostensibly).
With its highly trained and experienced Flight crew on a flag carrier built to exacting specifications, why do you not believe that had the crew had a Horizon, the a/c would not have ended up in the Ocean?
With a Horizon, and power, AB's suggested solution, pitch and power, would be expected to have worked. I believe it too. Call me old fashioned.
