Maj. Daniel Hilferty (left) and Capt. Joshua Linden (right) review the Joint Precision Airdrop System, or JPADS, data prior to an airdrop during a training mission Aug. 14, 2012, at Fort Hood, Texas. JPADS is a cargo parachute system that incorporates an onboard global positioning system able to guide the cargo with pinpoint accuracy to a designated drop zone. JPADS also allows cargo to be dropped from higher attitudes, allowing aircraft to safely avoid enemy ground fire. Hilferty is assigned to the 317th Operations Support Squadron. Linden is assigned to the 40th Airlift Squadron. (U.S. Air Force photo/Staff Sgt. Richard P. Ebensberger)
