BEIJING, Jan. 15 (Xinhuanet)-- Several dozen people in Stephenville, Texas, said they sighted what they believed is a UFO, U.S. media reported Tuesday.

    Residents in the small town insisted they saw a large object with bright lights flying low and fast but there were no photographs of them.

    "They were really, really bright," said Erath County Constable Lee Roy Gaitan.

    Dozens of others, including a pilot, a teacher and business owners in that area, reported seeing the same thing.

    The object may have been an illusion caused by two commercial airplanes, said Maj. Karl Lewis, a spokesman for the 301st Fighter Wing at the Joint Reserve Base Naval Air Station in Fort Worth.

    Lewis explained that lights from the aircraft would seem unusually bright and may appear orange from the setting sun.

    The U.S. Air Force said it had no planes in the area that night.

    "It wasn't an airplane," Gaitan said. "It wasn't a meteor, because it wouldn't have been bouncing around. It wasn't just one light."

    He said the lights were like nothing on Earth.

    The phenomenon has attracted the attention of UFO fans, who plan to descend on Stephenville on Saturday.
