A Republic of Korea Air Force Black Eagle pilot gives a thumbs-up while taxiing a T-50 aircraft to the flightline at Kunsan Air Base, ROK, Sept. 9, 2021. Each Back Eagle pilot must go through a vigorous selection process to be chosen to fly. One qualification is to have 600-800 flying hours prior to joining the team.
