Hundreds of rocket enthusiasts watch a 50-foot tall sport rocket while it was being hoisted upright on a launch pad at Ft. Carson near Colorado Springs, Colo., Sunday, July 24, 2016. Student interns from United Launch Alliance (ULA), Ball Aerospace and students from Colorado combined forces in the production.
