According to Aviation Herald the Airbus A319 performing flight 3U-8633 "from Chongqing to Lhasa (China), was en-route at 9800 meters (FL321) about 60nm west of Chengdu over mountainous terrain, when the right-hand windshield burst completely, the glass hitting and injuring the first officer".
He added, "When I looked at the other side, the co-pilot was partially blown out of the aircraft".
"I couldn't hear the radio", Liu said.
"The sudden loss of pressure and low temperature made me very uncomfortable and it was very hard to make a single move when the aircraft was flying at 900 kilometers (560 miles) an hour and at such a high altitude", Liu said, according to the Morning Post. It said it had switched the flight's passengers to another aircraft to carry on their journey to Lhasa.
None of the flight's 119 passengers were injured during the incident, but some were understandably a bit shaken up.
The ordeal occurred on a Sichuan Airlines flight that took place on Monday. It also has global routes to Canada, Japan and the Czech Republic. "I wanted to control the plane and land", he later told Sichuan Television.
Iran foreign minister scrambles to China and Russian Federation to save nuclear deal
EU foreign policy chief Federica Mogherini insisted European powers were serious about salvaging the deal. However, on Tuesday the USA hit Iran's central bank governor with sanctions.
Liu, who joined Sichuan Airlines after leaving the military in 2006, was able to right the plane quickly and made an emergency landing at Chengdu Shuangliu International Airport at 7:46, about 45 minutes after the windshield blew out. Passengers were being served their breakfast when the plane plunged suddenly to 24,000ft from above 30,000 feet.
Because he was wearing a seatbelt, the co-pilot was pulled back into the cockpit - sustaining only scratches to his face and a sprained wrist. In that case, the windscreen broke and caused the plane to lose cabin pressure and make an emergency landing.
Chinese who learned of the successful landing heaped praise on Liu, a former military pilot, for his life-saving maneuvers during a perilous situation.
Mobile phone footage emerged online shows flight attendants asking passengers to wear oxygen masks and putting on safety belts. Now, China's airlines have a "superb record" and the country is "considered an extremely safe place" for air travel, Thomas said. A flight attendant also received a minor injury during the accident. The airline did not immediately comment Tuesday about what led to the shattered windshield, but apologized and referred to the incident as "mechanical failures".
