Tech. Sgt. Joseph Parenteau, the 33rd Maintenance Squadron NCO in charge of low observables, teaches Christian Loafman, 9, how to place lettering on aircraft metals at Eglin Air Force Base, Fla., May 18, 2016. Christian, the base’s first F-35A Lightning II Pilot for a Day, toured the low observable and nondestructive inspection shops where he learned how Airmen check the aircraft to maintain its ability to fly safely.
