A Y-20B transport aircraft of the Chinese PLA Air Force on Monday afternoon took off and headed for South Korea to repatriate the remains of the 13th batch of Chinese People's Volunteers martyrs. After the Y-20B enters China's airspace on its return flight, four J-20 fighter jets of the PLA Air Force will provide escort. This marks the first time the Y-20B has been deployed for the repatriation mission, as well as the Y-20B’s first overseas mission.
