A 109th Aircraft Maintenance Squadron crew chief from Stratton Air National Guard Base, N.Y., does a routine pre-flight inspection on an LC-130 Hercules, equipped with retractable ski-wheels, at Joint Base Pearl Harbor-Hickam, Hawaii, on Oct. 18, 2010. The LC-130 is preparing for a flight to Antarctica to support Operation Deep Freeze. The uniquely equipped aircraft is necessary for the movement of personnel and cargo vital to the U.S. Antarctic Program and the National Science Foundation’s research and exploration efforts in Antarctica. The U.S. Air Force, Navy, Army, and Coast Guard lend operational and logistical support to support these efforts as part of Operation Deep Freeze. (U.S. Air Force photo/Senior Airman Gustavo Gonzalez)
