If San Francisco Bay Area residents don't want to watch the Super Bowl on Sunday, they can forget about flying drones.
The Federal Aviation Administration has banned all drones from flying anywhere within a 32-mile (52-kilometre) radius of Levi's Stadium as part of a complex and strict set of rules for all air traffic. That's a large area that includes all of Silicon Valley, San Jose, Oakland and most of San Francisco.
Drones, model aircraft, model rockets, hang gliding, crop dusting and parachuting are among the aviation activities banned from 2 p.m. to 11:59 p.m. on Sunday, Feb. 7. The game begins at 5 p.m.
The rules, which allow emergency, military and commercial air travel, are part of the major security operation being mounted to keep the stadium safe. On Wednesday, law enforcement officials said there is "no credible threat" against the event.
"With so many drones being sold for recreational use, we want to do everything we can to get the word out that the game is a No Drone Zone," FAA Administrator Michael Huerta said in a statement.
What happens if the rules are ignored?
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."
