WINFLY
A U.S. Air Force C-17 Globemaster III from Joint Base Lewis-McChord, Washington, taxis to a parking spot at Christchurch International Airport, New Zealand, Aug. 21, 2015. The aircraft was used to fly missions to Antarctica in support of the U.S. Antarctic Program’s WINFLY. WINFLY missions are flown using night vision goggles, because the sun doesn’t rise during winter in Antarctica. (U.S. Air Force photo by Senior Airman Madelyn McCullough)
