KC-135 Stratotankers assigned to MacDill Air Force Base, Fla., prepare for launch as part of an "Elephant Walk” on Jan. 20, 2012. Personnel from MacDill AFB’s total force integration, 6th Air Mobility Wing and 927th Air Reserve Wing, executed the mission and launched eight aircraft as part of the event. "Elephant Walk" is a historic, uniquely Air Force term that describes the nose-to-tail, single-file taxi movements of the aircraft synonymous with the nose-to-tail trail of lumbering elephants.
