Restricted airspace is an area (volume) of airspace in which the local controlling authorities have determined that air traffic must be restricted (if not continually prohibited) for safety or security concerns. It is one of many types of special use airspace designations and is depicted on aeronautical charts with the letter "R" followed by a serial number.
According to the United States Federal Aviation Administration (FAA): "Restricted areas denote the existence of unusual, often invisible, hazards to aircraft such as artillery firing, aerial gunnery, or guided missiles. Penetration of restricted areas without authorization from the using or controlling agency may be extremely hazardous to the aircraft and its occupants."

“Love is like some fresh spring, first a stream and then a river, changing its aspect and its nature as it flows to plunge itself in some boundless ocean, where restricted natures only find monotony, but where great souls are engulfed in endless contemplation.”
—Honoré De Balzac (1799–1850)
