Spinning metallic diamonds over Super Bowl

The objects that I am referring to where actually broadcast live during the 1980 (?)NFL Super Bowl between the Los Angeles Rams and the Pittsburgh Steelers.  During the game, a cameraman focus and zoomed-in on a couple of spinning diamond shaped objects that were over the Los Angeles Coliseum.  The network broadcasters noticed it and started talking about "how curious" the objects where.  The objects appeared to be metallic in structure and were hovering a few hundred feet above the staduim.  As they turned, you could make out the obvious flash of metal when the sunlight hit the sides of it.  It appeared to spin on its corner points (as if a compass - north and south) and in a left to right spin.  The cameras stayed on this for about 2 minutes and then the cameras cut back to the game.  It has been almost 22 years since I've seen this, but I clearly remember the things I saw.  They were not the Goodyear blimp, or any type of news helicopter covering the game.  My older brothers and some cousins and I were watching the game.  I was 13 at the time.  I remember that there was a news blurb about it later, but never remember seeing or hearing anything about it after that.  Unfortunatly I don't have a copy of the came, you may want to find a copy of the broadcast of this game to view.  I don't remember what quarter or time of the game this happened, but I do know I saw it all on live T.V.
