Bushwhacker would be the best choice, but I'm not so sure flying over a football game is. Lots of people around to hit and those kinds of things tend to be sensationalized. If you have your heart set on flying over a game MAKE ABSOLUTELY SURE IT IS OK WITH THE STAFF AND YOU ARE WELL AWAY FROM THE CROWD. Be safe. It certainly would be cool to see a banner pulling plane above a high school football game, we also have to keep other people's safety in mind.
