I just want to know if anyone knows what just lit up the night sky tonight ( 6/21/10 ) at 11:00 pm central time. I've experienced a similar event some years ago when Regan was president and the Starwars program was being tested. Although "Starwars" was denied as to ever exist, I am at a loss as to explain nighttime turning to day without some type of nuclear detonation in the upper atmosphere. This flash of extreme brightness wasn't caused by lightening....not a cloud in the sky and not caused by fireworks....this covered the sky and had no sound. Is someone experimenting with a nuclear device?????
