Justin Mohler, a teenager who has struggled with chronic kidney failure and received a transplant in November 2018, looks through night vision goggles during a base tour for Make-A-Wish South Dakota at Ellsworth Air Force Base, S.D., Feb. 26, 2019. The teen and his family visited several squadrons on base as part of the tour that culminated with a formal announcement that Justin’s dream to visit the Sept. 11 memorial in New York would be granted.
