A transport aircraft of the People's Liberation Army (PLA) Air Force is seen at Tianhe International Airport in Wuhan, central China's Hubei Province, Feb. 13, 2020. Ordered by the Central Military Commission, 11 transport aircraft of the People's Liberation Army Air Force Thursday sent medics and supplies provided by the armed forces to virus-hit Wuhan, capital of Hubei Province. This was the first time for China's domestically developed large transport aircraft Y-20 to take part in non-military action. It was also the first time for the Air Force to send large and medium transport aircraft on active service to carry out urgent air transport tasks on a large scale. (Xinhua/Li Yun)
