Is that a obviously yes or a obviously no answer Capn Bloggs?
Keeping in mind, no other breed of the 737 would have put a nose down input to the stabiliser.
As a side, a run away stabiliser you would expect after a input was made and a stop of input expected, but did not happen. That is not what happened in these two cases as no nose down input should have happened (it was not an over run, but more like a 1958 red Plymouth Fury event)
