Senior Airman Steven Brinley, 95th Aircraft Maintenance Unit crew chief, Tyndall AFB, Fla., inspects an F-22 Raptor during Red Flag 16-1, Jan. 28, 2016 at Nellis AFB, Nev. Maintainers are the lifeblood of the flightline, and with almost 80 planes taking off twice daily during Red Flag, it is their duty to ensure mission-essential aircraft leave and return safely.
