UK Queen's Windsor Castle to be no-fly zone amid safety concerns

Amid concerns over safety of UK's Queen Elizabeth II, her official residence, Windsor Castle, is set to become a no-fly zone. From January 27 onwards, aircrafts and drones will be prohibited from flying over castle at an altitude of 2,500ft. The decision was taken after a crossbow-wielding man broke into Windsor Castle on December 25 and threatened to kill Queen.
