An airport in Baotou, Inner Mongolia, was forced to shut to prevent passenger jets crashing into a UFO, according to reports.
Three flights to Baotou from Shanghai and Beijing were reportedly forced to circle the airport until the UFO disappeared.
Two other flights were diverted away from Baotou and to the nearby cities of Ordos and Taiyuan. The airport was shut for around an hour "to guarantee safety" according to a spokesman.
Witnesses reported a bright light shining in the sky on September 11 around two-and-a-half miles away from Baotou airport, before suddenly vanishing.
