A "No-Fly Zone" is an area where aircraft are not allowed to fly, usually established for safety or security reasons. These zones can be created by governments or international organizations to protect civilians, prevent military actions, or safeguard sensitive locations. Enforcement of a no-fly zone often involves military aircraft and radar systems to monitor and intercept any unauthorized flights. Examples of no-fly zones include those established during conflicts, such as in Iraq or Libya, where they aimed to limit the air capabilities of certain military forces and protect local populations.
