Flaming orange orb moving at high rates of speed, often becoming very bright.On July 4th, about ten of us were witnesses to a bright orange orb that flew West to East twice, than about an hour later it flew right over us going South over the town of Whitefish, MT. It was moving way too fast to be a Chinese lantern or flaming Hot air balloon. It looked round, or oval shaped and seemed to be flaming, often becoming very bright. There must have been many people in Whitefish that saw it, but it was being dismissed by some as being some kind of firework. However, I have never seen a firework that traveled that fast, and stayed lit, becoming very bright at times.
