As court documents describe, the FAA issues a temporary restriction that prohibits all aircraft, including drones, from operating within a three-nautical-mile radius of any stadium with a seating capacity of 30,000 or more people during, among other events, regular or post-season NFL games. The "stadium airspace is defined as "National Defense Airspace" and remains in effect for a specified time period before, during, and after NFL games at Levi's Stadium - which will include the Feb. 8 Super Bowl.
