Rejected by the United States Air Service for being too short, Harold Albert Kullberg joined the Royal Flying Corps in Canada on 7 August 1917. He was promoted to temporary 2nd Lieutenant (on probation) on 12 December 1917. In May 1918 he joined 1 Squadron in France to fly the S.E.5a. Scoring his final victory on 16 September 1918, Kullberg was hotly pursued by the companions of the Fokker D.VII he'd just shot down. Severely wounded three times in the leg, he spent the remainder of the war in hospital. Post-war he was president of the Akron Aeronautical Association and was killed, age 28, in a crash near Hudson, Ohio while teaching a student pilot to fly.
