I can understand the difference between an air show where people go to see low and dangerous maneuvers and a stadium fly over where a good part of the crowd does not even know there is to be a fly over. That being said, I believe these things should be done low and fast. We can't all live in a glass bubble forever. If I were at a stadium event where a fly over happened, I would be very disapointed if it were executed at multi-thousands of feet. I would want it low, loud, and fast.
