Pylon racing is where multiple planes fly around poles in the ground (pylons) to see who can go the fastest. Sometimes there are just two pylons, sometimes three (in a triangle). Generally ten laps are flown. a "cut" is when the plane turns too short and turns short of the pylon. There are judges that look at the pylons to make sure no one cuts the corner too short. The planes are generally low to the ground, but the pylon extends indefinitely upward for purposes of racing. So the planes do not literally have to go around the actual pylon (which is only about 15 feet in the air).
