Introduction Curiosity will eventually lead to innovation. Fortunately we are an imaginative species who does a lot of wondering. Way back to when man first learned to walk upright and began communicating with each other, by pointing and shouting, we can find the earliest examples. Somebody once thought, ‘I know, we can move that heavy rock, or dead buffalo, by rolling it along on tree trunks because it is easier than dragging it over the ground.’ This, of course, led to the wheel. It must have been around that time that some other clever soul worked out that if he held some meat over that hot fiery thing then it tasted better. It seems basic but it was innovation. Somebody somewhere decided to take the risk of burning their food down into ashes, as they knew the burning logs did, just to see if it tasted any better. But I bet there was someone else laughing at him and saying ‘don’t do that, it’s a terrible idea,’ (or whatever is was they would have said back then.) And that’s innovation too. That’s discovery and invention. We have been doing it ever since in one form or another and we have come a long way as a species thanks to people who take risks and ignore the advice of wiser ones. And that, in a nutshell, is what this book is all about. This, then, is the story of Frank Whittle and how he overcame huge odds to make sure his vision would win a war and change the world forever, despite fierce opposition from Her Majesty’s Royal Air Force.
