No. 610 Squadron of the Royal Air Force was a Squadron of the Auxiliary Air Force. Comprising very high quality pilots, often ex-RAF officers and occasionally locally based company Test pilots from companies such as de Havilland and Airwork, its pilots were initially part timers who would spend their weekends and spare time flying and practising combat manoeuvres. The squadron was named the "County of Chester" and adopted the motto "Alifero tollitur axe ceres"; which translates as "Ceres rising in a winged chariot", Ceres being the Roman Goddess of Wheat, a reference to Chester's Agricultural sector. Its badge contained the image of a garb.

The Royal Auxiliary Air Force (RAuxAF), formerly the Auxiliary Air Force (AAF), together with the Air Force Reserve, is a component of His Majesty's Reserve Air Forces. It provides a primary reinforcement capability for the regular service, and consists of paid volunteers who give up some of their weekends, evenings and holidays to train at one of a number of squadrons around the United Kingdom. Its current mission is to provide trained personnel in support of the regular RAF.
