A Joint Precision Airdrop System bundle floats to the ground after being dropped from the back of a C-130 Hercules aircraft over Afghanistan. This drop, made on 31st August 2006, from 17,500 feet, was the first joint Air Force-Army operational drop of JPADS in the US Central Command area of responsibility to re-supply ground troops with ammunition and water.
