An F-35A Lightning II assigned to the 421st Fighter Squadron takes off from Nellis Air Force Base, Nev., during Red Flag 20-1. Red Flag exercises give Airmen an opportunity to experience advanced, relevant and realistic combat situations in a controlled environment, increasing their ability to complete missions and safely return home. It also prepares maintenance personnel, ground controllers, and space and cyber operators to support those missions within the same tactical environment. (U.S. Air Force photo by R. Nial Bradshaw)
