Silicon Valley will be a no-drone-zone on Super Bowl Sunday.

The Federal Aviation Administration is banning all drones within 32 miles of San Francisco's Levi's Stadium from 2 p.m. to midnight on Sunday. Kickoff is at 6:30 p.m. 

F.A.A. regulations state that "The United States government may use deadly force against the airborne aircraft, if it is determined that the aircraft poses an imminent security threat," Computer World reports.

Despite the heightened security measures on Sunday, drones and sporting stadiums can, in fact, co-exist harmoniously. As reported, there's even a startup called the Drone Racing League, backed by RSE Ventures and Vayner Media CEO Gary Vaynerchuk, that held its first official race recently in the Miami Dolphins' Sun Life Stadium. The company is airing the event on its YouTube channel on February 22.

While recreational drones are increasingly becoming a mainstream consumer item, they're also causing serious problems that could make it harder for companies like Amazon to one day get the green light from regulators to use the unmanned flying machines for delivery purposes. Recreational drones have been secretly dropping contraband over prison walls at night in at least least five U.S. states, the AP reports.   

Florida senator Bill Nelson has written letters to the F.A.A., Homeland Security, NASA, and the Pentagon asking for their collaboration on establishing safety rules, citing the specific threat posed by drones flying near airports and prisons. 

U.S. lawmakers are expected to deliver a draft of the Federal Aviation Authority's reauthorization bill, will include rules for nonmilitary drones, this month.
