Book excerpt: First published in 1938, Teach Yourself To Fly was not only one of the very first Teach Yourself books to be published but the first to actually change the world. It was used on the eve of the second world war to prepare pilot recruits and conscripts before they were called for service, and as such it was read religiously by thousands of young men, some as young as 17, and directly impacted on the British war effort. This beautiful new printing of the book captures all of the feelings of that extraordinary time - it's nostalgic, understated, inspiring and very British indeed, warning young pilots, amongst other things, not to feel 'too discouraged' in the event of a crash landing. Technology has changed hugely, but the principles of aviation as they were in the middle of the twentieth century are perfectly summarised in this lovely book. Get hold of the right vehicle, and it really can teach you to fly. What happens when you're up there, however, is your responsibility. Since 1938, millions of people have learned to do the things they love with Teach Yourself. Welcome to the how-to guides that changed the modern world.
