Simpson joined Hawker in 1954 and became Hawker’s Chief Test Pilot in 1970. He flew the P.1127 as well as making the first flight in a Hawk. In 2011, the Guild of Air Pilots and Air Navigators awarded him the Guild Award of Honour in recognition of his outstanding lifetime contribution to aviation: “for his long record as a particularly accomplished pilot, his outstanding contribution to experimental test flying, his intimate involvement in bringing three iconic British Fighters – the Hunter, Harrier and Hawk – into service and his exemplary commitment to British aviation generally”.

The BAE Systems Hawk is a British single-engine, jet-powered advanced trainer aircraft. It was first flown at Dunsfold, Surrey, in 1974 as the Hawker Siddeley Hawk, and subsequently produced by its successor companies, British Aerospace and BAE Systems, respectively. It has been used in a training capacity and as a low-cost combat aircraft.
Operators of the Hawk include the Royal Air Force (notably the Red Arrows display team) and a considerable number of foreign military operators. The Hawk is still in production in the UK and under licence in India by Hindustan Aeronautics Limited (HAL) with over 900 Hawks sold to 18 operators around the world.
