Assuming your question is "legit" (I'm not biting, necessarily):
Even if it were midnight, and there wasn't direct, or ambient, autumn sunlight (like there will be at even 6:45, or even 7:45 p.m. on 9/12/09), a flyover in pitch dark, even with the stadium lights all off, would be impressive.
The fighters, or Blackhawks should they choose and given the opponent, have navigation and strobe lights; and if it is fighters, the sound and light from the afterburners alone would be impressive.
In the likely event you've given another electronic yank on the chain:
Of course, it's a good thing this will happen for the Air Force game, and not the Wisky game, or you'd have to disclose the no-flyover to your Bucky fans buying "your (alleged) seats". Alas, less profit, but since the dollar is a big motivator for you . . .
I also applaud your subversion and understated pot-stirring techniques.
