Walter Kloc made the 1,500 mile trek to take part in the graduation of his grandson, Joseph, from the the Air Force Academy in Colorado Springs.
The Air Force Academy said on Facebook that the crowd gave the World War II veteran a standing ovation during the ceremony, adding that "everyone in the room was gifted with a memory they'll never forget." Joseph Kloc called the event "(p)robably one of the best days of my life."
