Night goggles
Tech. Sgt. Matthew Freeman does an operational check of panoramic night vision goggles Monday, March, 6, 2006. The new goggles give pilots a 90-degree view. The 355th Expeditionary Fighter Squadron was chosen for the first operational use of the $65,000 devices because of the low-altitude mission of the unit's A-10 Thunderbolt II aircraft. Adjustment of the panoramic goggles is simplified with the use of snap-on diopter lenses. These lenses allow easy front-focus adjustment before and during flight. Sergeant Freeman is from of Tucson, Ariz., and deployed from Eielson Air Force Base, Alaska. (U.S. Air Force photo/Master Sgt. Lance Cheung)
