If you've ever wanted to know how something as heavy as a Boeing 747 or an Airbus A380 can lift hundreds of people and their luggage thousands of feet into the air and fly them halfway around the world, but didn't want to get bogged down in lots of mathematical formulae, then this is the book for you. The theory of flight is explained in layman's terms with lots of easy to follow diagrams and drawings. Apart from Seaton's coefficient, the lift equation used by the Wright brothers and featured on the cover, and a brief explanation of Bernoulli's theorem, there are no mathematics in this book. Apart from the basic theory, the book also looks at supersonic flight and finishing with a look at one or two of the pioneers who contributed to our rich avation history.
