Then it's up to the club that is hosting the event to tell this pilot to land and not fly in that manner again or he/she will be grounded for the rest of the event, and that encludes the after flying when the event is offically over. If you want to hold events like this again, then the host club has to take charge and enforce the rules. AMA will not step in at this time because the event ended at, let's say 5 PM.....
