Early in this thread Centaurus mentioned the use of bank to overcome extreme uncommanded nose up pitch changes. I vaguely recall an incident in mid NSW some years ago where the pilot of a piston twin (PA31 I think) used this technique to maintain a semblance of control. After wildly swooping around the countryside for some time he managed to get the aircraft on the ground, right side up, on a runway at a conveniently located airport. I have always considered that this was an outstanding example of piloting skill and airmanship. Does any one have the real details of that event to share with us.
