Mysterious lights in the night sky near Phoenix had some wondering if they were seeing UFOs. Police received a bunch of calls about the four strange lights hovering just above the horizon. The lights, captured on home video, could be seen for miles. Military officials said the lights were military flares dropped on the Barry Goldwater Gunnery Range outside Gila Bend, Ariz. They said the amber flares are used as targets. It was a training exercise out of the Marine Corps Air Station in Yuma, Ariz., officials said. The Federal Aviation Administration also reported that Luke Air Force Base had six F-16s that were also out on the range practicing ground attacks while using flares.
