NOFLYZONE
No-fly zone
A no-fly zone is a territory or an area over which aircraft are not permitted to fly. Such zones are usually set up in a military context, somewhat like a demilitarized zone in the sky, and usually prohibit military aircraft of a belligerent nation from operating in the region. Aircraft that break the no-fly zone may be shot down, depending on the terms of the NFZ.The above text is a snippet from Wikipedia: No-fly zone
