Drones banned from flying within 32 miles of Super Bowl
Drones have been banned from flying within 32 miles of American Football's Super Bowl, the Federal Aviation Administration (FAA) has said.
In a video to sports fans, the FAA warns the stadium is a "no-drone zone".
The restrictions cover anywhere within 32 miles of the Super Bowl stadium in Santa Clara, California, between 14:00 and 23:59 PST on 7 February.
FAA regulations also advise that "deadly force" may be used if a drone is perceived as a security threat.
The Super Bowl is the climax of the football season, and a crowd of 70,000 is expected for this year's game.
"Bring your lucky jersey, bring your facepaint, bring your team spirit," the video announces, "but leave your drone at home."
No-drone zones have become commonplace in the United States at sports and entertainment events at which large crowds gather.
Furthermore, permanent restrictions are in place over sensitive buildings - such as airports and the White House.
FAA regulations state: "The United States government may use deadly force against the airborne aircraft, if it is determined that the aircraft poses an imminent security threat."
