Actually looking at the Vid the actual pitch change in deg's was a total of near 11 deg's From +2.5 up normal flight Att to around -8.4 deg's downward. That's a large change in a short space of time.Also as we all know an aircraft pivots for want of a better word about it's wing so the further away from that balance point the more dramatic the pitching effect on anyone not strapped in.
We've all had fun pushing & pulling the control column of a light A/C to create pos & neg G's for our poor unsuspecting friends but the moment arm for the change was tiny compared to a large airliner.
Still I hear some of the pax are going to reject the $400K that QF are offering (in the news 2day) as they are doing a class action suit for millions !...ouch!!!
