What is ground staff? How to use in English

The term "ground staff" originated from the aviation industry in the early 20th century. As air travel became more common, the need for a workforce to handle various responsibilities on the ground before takeoff and after landing grew. These personnel, who work in close proximity to the aircraft, became known as "ground staff." The precise origins of the phrase are unclear, but it is thought to have emerged as a way to differentiate the workers responsible for tasks on the ground (such as loading and unloading luggage, refueling, and maintaining the aircraft) from the flight crew responsible for flying the plane. The term "ground staff" is now a widely used phrase in aviation and has come to encompass a diverse range of roles, from air traffic controllers and baggage handlers to technicians who maintain and repair aircraft on the ground. In summary, the words "ground staff" describe the group of individuals who work behind the scenes at airports and airfields to ensure the safe and efficient operation of aircraft before and after flights.
