Lightning and Stardust.
The north side of The Stardust had a large rotating sign with three sides. It was changed regularly with movie theater style letters, and served the purpose of advertising meals and events.
In August 2004 something happened to the sign. Apparently it was struck by lightning. The damage looked like a small explosion and fire.
Nobody reported actually seeing it being struck, but for more than a few days after, the damage remained for everyone to see.
The sign was repaired after more than a week. It might have been two weeks, as I remember being surprised at how long it remained in damaged condition.
Once repaired, the sign served out its job until it was removed during the demolition phase, a month or two prior to the implosion of The Stardust.
