Several sets of red, white, blue/green lights under triangular object East Rolling Prairie left in sky West.I spotted a triangular object in my backyard approximately 2 feet above tree top I was coming home from work that night the sky was clear I noticed this object was not moving I guess it was hovering no sound to it I had walked underneath it. It had several red, white, green/blue lights not blinking I was just amazed how huge this object was and no one seen it or heard it arrive. I live on a highway and cars come and go, that night around that time, hardly any out. I wasn't scared just curious I backed up where I parked my car in driveway and a this triangular started to take off extremely loud, ear piercing sound I in fact had to cover my ears and squatted down it moved over my head went into the sky west blinking white lights then disappeared but I could still see it three larger lights looked like orbs went into different directions. No one in my area has came forward Did they see this too and not saying anything?((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information. PD))
