Lieutenant Frederick Ernest Luff was an American flying ace during World War I. He was credited with five aerial victories, and awarded the British Distinguished Flying Cross.
Although he survived the war, he was injured in an air accident in May 1919 at Lorain, Ohio. He subsequently lived an invalid's life before expiring at home in Cleveland, Ohio in late April 1931.
Frederick Ernest Luff was born in Cleveland, Ohio on 9 July 1896.[1]
Luff joined the United States Army Air Service during World War I and was trained as a pilot. He was then forwarded to the Royal Air Force for service. They posted him to pilot's duty with No. 74 Squadron RAF to fly a Royal Aircraft Factory SE.5a. He destroyed three German Fokker D.VII fighters and two observation balloons between 19 August and 15 September 1918, earning a Distinguished Flying Cross for his deeds. On 19 September, he rejoined the USAAS and was assigned to the 25th Aero Squadron. He and the 25th moved into combat on 9 November 1918, but the war ended two days later.[1] The present-day U.S. Air Force unit, the 25th Space Range Squadron, traces its lineage back to the 25th Aero Squadron and recognizes Luff as a founding member.
Luff returned to the United States after the war, and survived an airplane crash at Lorain, Ohio in May 1919. However, injuries suffered in the accident left him an invalid until he died in his parents' home[1] on 27[2] or 28 April 1931.[1]
