Strange bright orange lights in South Pittsburgh sky.Driving along Route 8,8 we noticed 4 bright orange color lights just sitting in the sky in a square shape. As we continued to drive the lights began to slowly move closer to each other. That is when we realized they were individual lights rather than lights from one object. Then they began to move in fast circular motion and more came. Started receiving facebook messages and video from others witnessing the same sighting. Dogs were barking continuously and eventually would just whimper in friends' neighborhood. We started seeing helicopters flying and police rushing toward the area. We never stopped. Just kept driving to get home.
