U.S. Air Force people build Tri-Wall Aerial Delivery System (TRIADS) that will hold the Humanitarian Daily Rations. C-17 Globemaster IIIs deliver the HDRs in Support of Operation Enduring Freedom. The C-17s airdrop the HDRs to Afghan refugees who have massed inside the borders of Afghanistan. C-17s can carry more than 35,000 HDR’s packaged in 84 TRIAD boxes, measuring 80 inches tall and 48 by 48 inches square, each filled with 420 HDRs. (U.S. Air Force photo by Staff Sgt. Jeremy T. Lock)
