KC-135 Stratotanker elephant walk
Fourteen KC-135 Stratotankers line up during a simulated alert call, March 24, 2016, at McConnell Air Force Base, Kan. The elephant walk was part of an exercise, which displayed the rapid mobility capabilities and teamwork of the men and women at McConnell to take flight within minutes of being notified of a mission.
