The U.S. Air Force  C-17 Globemaster III  carried 51 people south to the main hub of the U.S. Antarctic Program (USAP) , which is managed by the National Science Foundation (NSF) . A second flight, using night vision goggle capability and carrying only cargo, was scheduled to reach McMurdo on Aug. 17.

The two flights represent the first phase of what’s known as winter fly-in, or winfly, when a vanguard of support personnel arrive at McMurdo to help prepare the station for the busy Antarctic research season, which begins in October and runs through the end of February.

Three more flights are planned for the first week of September, using the Australian Antarctic Division’s Airbus A319 . An estimated 99 people will arrive that week. The next flight won’t be until Oct. 3, when a Royal New Zealand Air Force B-757 will kick off the 2013-14 field season. New Zealand’s Scott Base is co-located with McMurdo on Ross Island.
