Staff Sgt. Courtney Armstrong, 28th Aircraft Maintenance Squadron crew chief, gives a tour of a B-1B to Ed Butler, a medically-retired U.S. Army veteran, and Butler’s granddaughter, Makennah Woods, at Ellsworth Air Force Base, S.D., Jan. 17, 2012. After being diagnosed with terminal cancer, one of Butler’s last wishes was to see one of Ellsworth’s B-1 bombers upclose. (U.S. Air Force photo by Airman 1st Class Kate Thornton/Released)
