Big Pistons Forever - we'll have to agree to disagree as we're just going around in circles. Please tell me where any pilot gets the training skills for a jammed control surface. What happened in the preceding minutes before the dreadful event is neither here nor there. The pilot clearly knew how to perform a loop as evidence was heard thereof.
Come on, we've got ATPL's here who can't even find the right airfield and you are having a pop at a ppl for not being able to cope with a jammed rudder.
