As the world watched in awe as the first jet powered aircraft appeared in the skies over Europe towards the end of WWII, capable of attaining speeds over 100 mph faster than the latest piston engined fighters, it is interesting to note that development work on jet propulsion actually started in the 1930s, with engineers in both Britain and Germany searching for the next generation of engine power. Indeed, the first flight of a turbojet powered aircraft actually took place just days before the outbreak of the Second World War, however, conflict would necessitate the production of thousands of aircraft powered by existing piston technology, so jet powered advancement proved to be relatively slow. In Britain, brilliant engineer Frank Whittle produced a viable turbojet engine and when the powerplant was installed in the Gloster E28/39 Pioneer for its first flight on 15th May 1941, it became the first British jet powered aircraft to fly - the race was now on to produce the first jet fighter for the Royal Air Force.
