WRIGHT-PATTERSON AIR FORCE BASE, Ohio - Two teams race against the clock to complete the 87th Aerial Port Squadron team building challenge that included push-ups, carrying a litter of planks followed by executing 25 jumping jacks, then exchanging the planks for an egg before crossing the finish line without dropping it. The challenge was part of the 445th Airlift Wing annual Wingman Day held during the April 21 unit training assembly. (U.S. Air Force photo/Staff Sgt. Amanda Duncan)
