During the winter season at the South Pole, temperatures often
dip as low as minus 100 F and can paralyze an aircraft's hydraulic
systems, crystallize the fuel and solidify lubricants. However,
freezing temperatures did not deter Joint Task Force-Support Forces
Antarctica Operation Deep Freeze crews and support personnel from
validating the C-17 Globemaster III's polar airdrop capability by
successfully airdropping 22,372 pounds of supplies to the South
Pole Dec. 18.
