Pitts S1-11B Super Stinker, owned by Vince Felton, at SABC Annual Fly In, Serpentine Airfield – Sun 27 September 2015. This is the final iteration of the famous Pitts Special aerobatic biplane, the prototype of which first flew in 1944. Several aircraft that Curtis Pitts built had a picture of a skunk on them and were called “Stinkers”. The prototype Model 11 (later called S1-11B) was called the “Super Stinker”. Pitts biplanes dominated world aerobatic competitions in the 1960s and 1970s, and are still competitive today. Photo © David Eyre
