Officials said the incident happened Monday when the windshield shattered on Sichuan Airlines Flight 3U8633. A cabin attendant was slightly hurt during the descent, according to the Civil Aviation Administration of China (CAAC).
The co-pilot was cut on the face and suffered an injury to the lower back. "We just tried our best to reassure the passengers and make everyone believe us that we could touch down safely", Zhou Yanwen, the injured flight attendant, was quoted as saying by China News Service.
But "everything in the cockpit was floating in the air".
Mr Liu had to land the Airbus A319 immediately, a task made more hard because the instruments malfunctioned and it was too loud to use the radio. Along with the pilot, a cabin crew member of the airline also suffered injuries though the injuries are of minor nature.
The Sichuan Airlines flight departed from the central Chinese municipality of Chongqing at 6.30am on Monday morning, due to arrive in Lhasa, Tibet at 9.30am. One other cabin crew member was injured during the emergency landing, in Chengdu, Sichuan province, although no further details were given.
Liu Chuanjian braved the intense cold and blasting wind to coax the plane into a safe landing in southwest China.
'I couldn't hear the radio and the cockpit's temperature dropped to minus 40 degree Celsius, ' he said.
