As we all now know from earlier posts, no such thing as "stall speed" its all about AoA. The A340 clearly went into a 'ballistic trajectory" too slow to maintain level flight at that altitude even with full thrust, around 20 seconds of "less than 1g" as it went over the top with a sharp drop in pitch angle? Its not too clear to me whether it was the pilot or protections that successfully managed the flightpath to recover speed. No mention of stall warnings, and as previously commented AoA not shown, nor how how deep the nose down pitch during recovery.
