HONG KONG — A Sichuan Airlines plane heading for Tibet made an emergency landing on Monday after its windshield shattered and a co-pilot was partially sucked out of the cockpit, the local news media reported.

Flight 8633 left the southwestern metropolis of Chongqing at 6:26 a.m. and was scheduled to land at 9:05 a.m. in the Tibetan capital, Lhasa, around 1,500 miles west, according to the flight tracking website FlightView.com.

But the windshield later “shattered with a loud sound,” the pilot, Liu Chuanjian, said in a video posted by the news outlet Chengdu Business News. “When I looked over to my side, half of my co-pilot’s body was hanging out of the window.”

“Fortunately, he was wearing a seatbelt,” Mr. Liu said.

The plane made an emergency landing at 7:42 a.m. in the southwestern Chinese city of Chengdu.
