multiple color UFO's over St. Joseph, MOMe and my dad were looking at the stars laying on the ground. We then saw a circle UFO travelling at a high rate of speed. It was circle shaped and was blinking from red to green to white. It moved across the sky very fast and changed directions. We saw a total of four crafts all were similar in their blinking colors. We are not sure it’s a UFO but everything it did was the same as the from NASA website videos describing UFOs
