Aerial refueling, also known as air-to-air refueling or in-flight refueling, is the process of transferring fuel from one aircraft to another while they are flying. It requires a highly specialized skill that only experienced pilots and aircrew can perform safely and effectively. Aerial refueling is essential for extending the range and endurance of military aircraft, allowing them to operate for longer periods of time without landing to refuel. It is also used in civilian aviation for certain missions, such as firefighting and long-haul flights.
