Me and my wife were driving down U.S.51 Highway at approximately 6 p.m. headed south bound toward Hazelhurst Mississipi when we saw a bright blue circular UFO. The UFO appeared on the west streaking across the sky, which was in our vision, and disappeared on the east side. It flew unreal speed much faster than a asteroid or meteorite. The equivalent of time i would say being 1.25 seconds.
