Geoff Crammond is a computer game designer and programmer who specialises in motor racing games. A former defence industry systems engineer, he claims to have had little interest in motor racing before programming his first racing game (Revs) back in 1984, but he holds a physics degree, which may explain the realism of some of his programming. As a consequence of that project he became a big fan of Formula One motor racing. At the end of the 80s, this interest, plus the ever improving capabilities of home computers, inspired him to specialise in programming Formula One racing simulations. Games One of his early releases was Aviator, a Spitfire simulator released by Acornsoft for the BBC Micro in March 1984. Having been motivated to make his own flight simulator from the hardware level upwards, Crammond identified the possibility of using one of the increasingly sophisticated home computers, if only "to cannibalise it". Recognising the potential of the BBC Micro, he ordered one in 1981 and, upon receiving it six months later, then set about familiarising himself with the system, taking a detour to produce a Space Invaders clone, Super Invaders, which was accepted for publication and sold by Acornsoft. Discussion with Acornsoft about his plans for making a flight simulator led to the Aviator concept, and the program itself was written in a period of nine months. Although displayed in only four colours and has few of the features of modern simulators for more powerful computers, Aviator was of unparalleled quality at the time of its release, with a realistic flight model that included g-forces that could tear the wings off in a dive. This would be accompanied by a continuous high pitched beep. The wings could be restored by removing the physical pressure on the airframe which was causing the flight envelope to be exceeded. Generally, this could be achieved by returning the joystick to a neutral centre position. The landscape was crudely rendered, and was basically a plane. Some scenic features were drawn as vector graphics, including low hills, fields, a lake, a suspension bridge over a river, and a small town which comprised a cluster of three buildings. Bonus points could be earned for flying under the bridge or along the main street of the town at a lower altitude than the buildings. Double points were earned for performing these stunts upside down. The game also had
