3 balls of different lights, slowly rotating in a triangular formation were seen tonight over tinley park, il.I was on my way home from the train station and noticed something odd in the sky. Three ballst of light, flashing different colors - looked like it was slowly rotating. The balls of light stayed in a triangular formation and moved slowly to the east.I tried to get closer to the formation to prove that it was just my imagination or something logical -- but I could never get close to it. It also seemed like there were an extra large amount of aircraft in the sky.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information. PD))
