2016 Defenders of Liberty Airshow
A C-17 Globemaster III is on display during the 2016 Defenders of Liberty Airshow at Barksdale Air Force Base, La., April 30. The inherent flexibility of the C-17 allows it to fulfill the worldwide air mobility requirements of the U.S. through rapid strategic delivery of troops and cargo.
