C-17 Globemaster III instructor pilots assigned to the 58th Airlift Squadron experiment with a new virtual, high-resolution, night vision goggle (NVG) training system, Dec. 9, 2019, at Altus Air Force Base, Okla. The new virtual NVG training system provides Airmen with a high-resolution, projector-based screen that almost directly reflects what student can expect to see in the cockpit.
