3. C17A Globemaster III

I know, $328 million may sound a bit excessive for a military airplane. However, the C17A Globemaster III is worth its price. This aircraft is a key element to successful warfare, for it is a transport plane used to move troops safely into and out of war zones. Used since 1993 by the Air Force, this plane is also used to perform medical evaluations and airdrop missions.
