JOINT BASE ANDREWS, MD - JULY 2: Air Force One, with United States President Barack Obama aboard, taxis for take-off on July 2, 2015 at Joint Base Andrews, in Maryland. The designation "Air Force One" is extended to any airplane transporting the President of the U.S. For the President's trip to LaCrosse, Wisconsin, the smaller C-32, which is a specially configured Boeing 757-200, was used, instead of the familiar VC-25. In addition to its occasional use for Presidential travel, the C-32 regularly transports the Vice President, the first lady, members of the Cabinet and members of Congress.
