The Boeing 737 is undoubtedly one of the best known of all passenger aircraft and has been built in greater numbers than any other commercial aircraft in the world. There are few airline passengers of the last decade who have not yet flown on one of these aircraft. More than 10,000 examples have been built in all its variants - an unbelievably high number for an airliner. This book describes the aircraft's early development - from the first concept drawings in the early 1960s to construction, testing, and first flights - to the present, with exciting photos, drawings, and information from the Boeing company archives. From the 737-100 through to today's 737MAX, all versions are covered in detail, including its use by many of the world's airlines, including Air France, British Airways, Delta, Easyjet, Lufthansa, SAS, Southwest, and many others.
