This book, simply put, is the story of helicopters told from the American point of view. And it's high time somebody did devote a book to those bizarre, noisy ""whirli-birds"" which more and more are becoming an important facet of American transportation. The author believes they will be of much more importance in a few years, due to the nation's population growth, traffic jams, and so on. Telling the story of early helicopter ideas going back to and Roger Bacon, he recounts first attempts at perpendicular right in this century in different nations, giving much deserved attention to the work of the brilliant Skorsky. The peaceful and military uses of the helicopter are thoroughly, its present role is given much statistical background, and its fascinating future is forecast. Although the book is filled too much semi-technical data and economic facts to make it appealing to a very wide audience, it is a must for those in flying, transportation, military, or modern business fields.
