The state-owned CCTV telecast a video released by the PLA on its WeChat account on July 17 for the first time showing a Y-9 aircraft deployed by China's Western Theatre Command transferring a critically injured officer from a base in Tibet to a hospital in Xian. The South China Morning Post (July 19) quoted a Beijing-based military source as saying the plane is just one element of the PLA’s drive to improve medical support at high altitudes, especially on the disputed border with India. The anonymous source added, “The Y-9 flying hospital will play a key role for transferring the critically wounded, while many local hospitals near the border on the Himalayas have been equipped with hyperbaric oxygen chambers for first aid treatment.”
