Capt. Brandon Packard, 37th Bomb Squadron weapons systems officer, climbs into a B-1 bomber at Ellsworth Air Force Base, S.D., June 30, 2015 prior to flying it to Tinker Air Force Base, Okla., to receive Integrated Battle Station systems upgrades. Ellsworth sent its first B-1 to Tinker for the upgrade to help modernize the aircraft by making it more user friendly for B-1 pilots and maintainers.
