Most readers will know the nickname "King of the Skies." To most, it refers to Airbus's double-decker superjumbo. It was initially coined for an American piston-powered aircraft: the Cessna 210. The official marketing name for this airplane was the Centurion, which first flew in 1957. The airframe was based around the Cessna 182B Skylane and differed mostly thanks to the retractable landing gear.
