The invention by Whittle of the turbo-jet engine, and the determined effort to design, develop and demonstrate that such a novel new method of propulsion would replace piston engines in the air, was one of the most important technical achievements of the twentieth century. That one man accomplished this working with a small but dedicated team of engineers and craftsman in the middle of a war, and in the face of many doubters, was a truly monumental achievement. The jet engine envisaged by Frank Whittle, a young Royal Air Force cadet, changed aviation forever. It was an invention that has, in the years since, had the effect of shrinking the world we live in. We think nothing today of flying between continents in a few hours, when just a two or three generations ago this would have been a major expedition. In short, the jet engine, developed with great tenacity by Whittle, has made the world a village, and has introduced world-wide travel to ordinary people everywhere. This accomplishmen
