It's sort of a private pilot's worst nightmare, seeing a US Air Force fighter jet fly alongside your aircraft.
Whoops, that's because you've flown into restricted airspace.
And just like the airspace above Levi's Stadium in Santa Clara, California, the location of Super Bowl 50 this Sunday, a US Air Force F-15 Eagle will intercept all unapproved aircraft.
A Civil Air Patrol (CAP) Cessna 182 will assist the F-15.
In order to make this clear, the Civil Air Patrol recently posted the following video, taken from a Cessna 182, showing a practice intercept by an F-15 in preparation for the event.
