First flight during Thracian Viper 20
A U.S. Air Force pilot from the 555th Fighter Squadron, Aviano Air Base, Italy, performs a pre-flight check on a U.S. Air Force F-16 Fighting Falcon at Graf Ignatievo Air Base, Bulgaria, Sept. 21, 2020. This exercise required all levels of a squadron to deploy small teams of Airmen and aircraft for a short amount of time to hone their skills. Thracian Viper 20 also enhanced their ability to rapidly deploy to a remote location, establish command and control and deliver lethal airpower more effectively and efficiently anywhere in the world.
