U.S. Marines with Marine Barracks Washington stand

U.S. Marines with Marine Barracks Washington stand in formation as the hearse carrying the casket of Sen. John H. Glenn, Jr., arrives at Ohio State University, Columbus, Ohio, on Dec. 17, 2016. Having flown 149 combat missions in World War II and the Korean War, Glenn became the first American to orbit the earth in 1962. After retiring from the space program, Glenn was elected to the U.S. Senate in 1974 to represent the state of Ohio. (U.S. Marine Corps photo by Lance Cpl. Paul A. Ochoa)
