Flights were re-routed or forced to circle an airport for over an hour after Chinese air traffic controllers saw what they believed to be a UFO hovering over the runway.
The incident, which took place at about 8 p.m. on Sept. 11 at an airport in Baotou, is the eighth reported UFO sighting in China since June, according to AOL News. Back-to-back sightings in June alarmed Chinese residents.
As ABC reports:
The alert was triggered by bright lights in the sky that moved erratically, but reports claim that air traffic controllers at the Hohhot Air Traffic Management Bureau spotted the object on their radar. After about an hour, the object and the lights suddenly vanished and passenger jets were allowed to land.
While the others were dismissed as part of routine military exercises, the Chinese government has refused to comment on this sighting, according to The Sun.
