Feature: Chinese families mourned pilots killed in U.S. training accidents in 1940s

A formal memorial service is held to commemorate fallen Chinese pilots at the Fort Bliss National Cemetery in El Paso, Texas, the United States, on May 13, 2019. More than seven decades ago, groups of young Chinese came to the United States for military flight trainings against Japanese invasion. Unfortunately, 52 of them were killed during pilot trainings. Now, for the first time in more than half a century, relatives of those killed Chinese cadets made an arduous journey to El Paso, U.S. state of Texas, for belated reunions with their deceased family members.
