If not I really can't understand their insistence to keep the nose up - there is no way they could not feel the stall.
It's called a mind-set, a good example of that is the pilots of a Boeing freighter who's pitoheads froze and the air speed started to increase so they pulled the nose up, the speed continued to increase so they pulled it up some more and some more again, by this time common sense should have been screaming at them that you cant just keep pulling the nose up and continue to speed up, eventually they pulled once to often and stalled with fatal results.
