"The airport received a notice from the Hohhot Air Traffic Management Bureau about the appearance of an UFO. To guarantee security, the aircraft heading for the airport had to land at secondary airports. Otherwise, it may have led to collisions," said Ms. Luo, from the Baotou Airport.
Around 9:14 p.m., three flights from Beijing and Shanghai to Baotou were delayed, and the aircraft were forced to circle in the air while waiting to land.
Furthermore, the Air China Flight 1107 from Beijing to Baotou landed at the Erdos Airport and the Juneyao Airlines Flight 1137 from Shanghai to Baotou landed at the Taiyuan Airport.
The Baotou Airport did not receive a notice on resuming normal operations until 10 p.m.
