A C-17 Globemaster III flies a mission in support of exercise Purple Dragon on June 17, 2000. The C-17 is the newest, most flexible cargo aircraft to enter the airlift force. The C-17 is capable of rapid strategic delivery of troops and all types of cargo to main operating bases or directly to forward bases in the deployment area. The aircraft is also able to perform tactical airlift and airdrop missions when required. The inherent flexibility and performance characteristics of the C-17 force improve the ability of the total airlift system to fulfill the worldwide air mobility requirements of the United States.(U.S. Air Force photo by Technical Sgt.
