The famous B-52 Stratofortress has been in service with the USAF for more than 65 years and its iconic shape is known and recognised all over the world. Yet the B-52 and its predecessor, the B-47 Stratojet, started out looking very different indeed. Each aircraft was the end product of a lengthy design process which saw numerous configurations studied – with plenty of diversions taken and missteps made along the way.In Boeing B-47 Stratojet and B-52 Stratofortress: Origins and Evolution, aerospace engineer Scott Lowther reviews and explains the many different projects put forward for these two iconic aircraft, including a wide variety of rare and forgotten designs.Providing full-page diagrams, a wealth of new artwork and accurate data, the book will be useful for model makers interested in new and unique projects, aerospace engineers curious about the process of design evolution and those interested in these fascinating aircraft.
