Had they had 'conventional' controls, F/O Bonins' full nose up control input would have been a thousand times more obvious as he would have been hauling back on the yoke and probably with both hands.
can someone tell me (an interested slf) how it works with boeing´s 777 and 787 which are fbw as well but have no sidesticks? do both the yokes move the same? can one pilot feel the "force" performed by the other pilot?
