Senior Airman Airin Harmon, 4th Operations Support Squadron aircrew flight equipment journeyman, inspects night vision goggles used by F-15E Strike Eagle pilots at Seymour Johnson Air Force Base, North Carolina, Sept. 8, 2020. Harmon inspected the goggles for cracks on the lens. Night vision goggles are light image devices that use both visible light and infrared light to provide pilots a clearer image of their surroundings.
