No, I think there was somebody else on the flight deck who knew nothing about aeroplanes and flying and who thinks that to descend quickly you just push the stick forward.
Think about what you have just said, if someone other than crew entered the cockpit do you think the other crew member would be so quite on the CVR tape !!!! and if this person knew nothing about aeroplanes and flying but knew enough about how to lock the door !!!
