I have heard suggestions that the situation whilst due to the interplay between many factors (extra weight/position/thrust of larger engine, system software control beyond the immediate control of the pilot, etc..) that the disaster(s) may have been set off by a malfunctioning Angle of Attack sensor / vane of which (possibly) the aircraft "only"(?) had one. With certain safety critical systems, which rely on sensor input, 2-3 sensor inputs is not uncommon.
There was also a story that the DAY BEFORE the Lion Air (similar) collision last year, that an off-duty pilot had been able to intervene and AVOID DISASTER by assisting the Captain & 1st officer by diagnosing and shutting down the errant control system. The plane then went on and landed safely, but crashed on its next flight the next day due to an apparently similar situation. It's hard to believe that such a disaster would have occurred if there was proper analysis the day prior. Not good.
