A construction worker secures a piece of rebar to the floor of Hangar 1125, April 30, 2015, at McConnell Air Force Base, Kan. The rebar reinforces the concrete floor once it is poured. Hangar 1125 will be used for general maintenance on the KC-46A Pegasus once it is delivered to McConnell, which is scheduled to happen in August 2016. (U.S. Air Force photo by Staff Sgt.
