James Bryant (L) and his son Ben Bryant pose in front of the memorial posters at the 4th Sino-American Second World War Friendship and Flying Tiger History Conference in Las Vegas, the United States, May 11, 2019. James Bryant will never forget the day when his 93-year-old father went back to his bedroom and came back with a flight brief case containing papers related to the training and assignments he took as a U.S. Flying Tiger pilot during the World War II. As a "remarkable" yet "humble" man and a loving father, James E. Bryant did not show any detailed evidence about his war experience until about three years ago, the son recalled. (Xinhua/Han Fang)
