Narrative:

I was circling byu stadium with banner and an unannounced aircraft flew in front of me directly over the stadium. I announced to him what had happened. He didn't see me. I asked him to climb 500 ft and circle the same direction. He did. Other aircraft approaching the stadium, I asked them to fly at 500 ft intervals. The airspace over the stadium is popular on game days.
