 The C-17 Globemaster made its maiden flight in 1991 and has since proved itself as one of the Air Force's most versatile cargo aircraft. Capable of carrying over 170,000 pounds and claiming a top speed over 500 miles per hour, the C-17 is one of the best aircraft in its class. This record-breaking aircraft shows no signs of slowing down and will continue to be a pivotal member of the Air Force fleet.
