Ray Deacon was born in Farnborough, Kent, in 1942, grew up in South-East London and went on to study at William Penn Technical School before joining the Royal Air Force. On passing out in December 1959, he was posted to the Central Flying School (CFS), before arranging an exchange with a fellow radio mechanic on the DH Vampire T.11 line. Much to Ray's delight, the squadron was also responsible for handling Hawker Hunters the CFS Type Flight whenever they paid visits from their operating base at RAF Kemble. The opportunity to work on the 'queen of the skies' kindled a passion that has remained with him ever since. His career in the Royal Air Force involved service in Aden, where he lived for two years, working on a busy front-line operational squadron equipped with the more potent ground attack and fighter reconnaissance versions of Hawkers impeccable aircraft. He also worked at RAF Little Rissington on the Varsity squadron, a posting that was followed by time spent at the CFS Gnat Base Engineering Team, where he became familiar with the Gnats operating with the Red Arrows Aerobatic Team and 4 Squadron CFS. He left the RAF in May 1967.

A year with the RAE at Farnborough was followed by a 25-year career in computing with IBM. Early retirement enabled Ray to dedicate his free time to carrying out in-depth studies of his favorite subjects; RAF Little Rissington during the CFS years and Hawker Hunter operations in the Middle East.
