The son of a Brazilian father and British mother, Gordon Fox Rule was born in Brazil but raised in England. He attended Eastbourne College from January 1914 to December 1916. He joined the Royal Flying Corps in 1917 and was posted to 49 Squadron in January 1918, becoming a flight commander and Captain on 15 May 1918. Before returning to the Home Establishment on 14 August 1918, he scored seven victories flying D.H.4 and D.H.9 aircraft. In 1921, he resigned his commission in the Royal Air Force due to ill health.
Despite a strong accent, Gordon Fox Rule was fluent in Portuguese and very proud of the fact that he was a true Brazilian. At the age of thirty, he returned to Brazil where he would receive the 17th Brazilian brevet. Before his death in 1987, he sent all his mementos, photos and documents from World War I and his flying career to the Imperial War Museum in London.

Lieut. (T./Capt.) Gordon Fox-Rule.
Whilst on a bombing raid this officer dived to 100 feet and obtained a direct hit on a bridge, completely destroying it. Seeing a body of the enemy on the bank of the river he attacked them, causing them to disperse in disorder. He was then attacked by five biplanes; these he drove off, though his observer had been hit twice, and he landed safely at a French aerodrome. In all, he has taken part in thirty bomb raids and ten photographic reconnaissances, invariably displaying a marked offensive spirit.
