An Air Force C-17 Globemaster III, such as the one pictured in this file photo, flew through Russian airspace Oct. 7, operating under an agreement reached between U.S. and Russian officials in July. The new transit agreement will permit 4,500 flights to pass through Russian air space per year and will save the U.S. government up to $133 million annually in fuel, maintenance and other transportation costs, according to a White House fact sheet.
