Here is a rare look at a Boeing C-32 being refueled from a KC-10. The Boeing C-32 is a military passenger transportation version of the Boeing 757 for the United States Air Force. The C-32 provides transportation for United States leaders to locations around the world. The primary customers are the Vice President of the United States, using the distinctive call sign “Air Force Two”, the First Lady, and occasionally members of the U.S. Cabinet and U.S. Congress. Presidents Barack Obama, George W. Bush and Bill Clinton have at times flown on a C-32 as Air Force One in place of the larger VC-25A.
