Station hack

A Station hack, in Royal Air Force jargon, is a utility aeroplane assigned to an RAF air station or squadron (that normally flies another type of aircraft in its role), and utilised for run-of-the-mill activities, including delivering to, or collecting from, other airfields personnel, spare parts, equipment, or documents; activities that would not be considered worthy of the tactical, strategic, or larger transport aeroplanes that might be operated from the same air station.

The term is derived from the equestrian term for a horse used by competitive riders for everyday, run-of-the-mill riding, as opposed to those used for competitive riding.
