Excuse me for butting in here, but I believe that there's some confusion on Hanno's airplane at the World Champs. If it was the World Champs in Pensacola, Hanno was flying a 'Supra" and he was using a Supertigre .61 side exhaust with a pipe and retracts. I remember watching him fly one flight. Few people who never saw him in person knew that he used braces to walk. However, I grew up watching some of the best pattern flyers in the South and could tell when I saw greatness. Hanno was in a class all to himself!
