This very thorough study of 707 development and its service history is interesting and informative, but includes so much peripheral material, such as a large section devoted to a complete rundown of all KC-135 variants, that it becomes a reference work. Some of the side tracks are worthwhile, but not all. How Boeing sold the USAF on the KC-135 was integral to the 707 story, but the myriad uses to which that airframe was put over the next 30 years were not. While the 707 was the airplane that triggered the era of global air travel, its impact is arguably less than Boeing's next huge gamble, the jumbo jet. Sales of the 707 were in decline when the 747 was introduced in 1970, but the introduction of its huge cousin signaled a seismic shift from government subsidized carriers to profitable airlines that needed cost effective aircraft like the 727, 737 and 747. For a jet that was born as a military tanker, it's fitting that the last one to roll out was an E-3C AWACS, yet another offspring of the 707 that became famous in it own right. The strength of this book is how well it conveys the fundamental strength of Boeing's design. Every part of the plane could be and was upgraded, improved or replaced essentially letting the 707 keep evolving into a new aircraft for 33 years. The main weakness of this book is that Mr. Simons conveys, perhaps unintentionally, a dislike of Boeing which gives his narrative an odd tone. That said, anyone interested in the plane that epitomized the dawning jet age will find that story told here and much more. Recommended to readers in that category.
