Endres' beautiful work includes just about every aircraft, from the smallest commuter to the largest airliner with excellent photos, overviews of development, specs, and detailed internal diagrams (2 full pages for most aircraft). It also includes very interesting sections on flight operations, aircraft and engine design, and the future of commercial flight. The book does suffer so many chronic typos and technical errors that you're left wondering if the manuscript was proofread at all. It also tends to slant towards British-produced aircraft, but that's sort of a nice change. The breadth of information and the excellent diagrams are this book's strengths.
