His RAF career began as a consultant in aviation medicine, followed by his appointment as commandant of the
RAF Institute of Aviation Medicine in 1975, a post he held until 1988. Other appointments included; Dean of Air Force Medicine from 1985 to 1987, The
Queen's Honorary Physician from 1982 to 1988 and that of Royal Air Force's Senior Consultant from 1987 to 1988. Howard gained some notoriety in 1962, as the first man to test the world's first rocket-powered ejector seat, developed by the
Martin-Baker company. The rocket-powered ejector seat had distinct advantages over the original explosive cartridge seats in that it subjected the ejecting airmen to much lower G forces, thus reducing the risk of injuries. Howard's last major project prior to his retirement was his involvement in the selection of Britain's first two
astronauts,
Helen Sharman and
Tim Mace. ==Awards==
