Book excerpt: A comprehensive history of the aircraft that transformed commercial aviation. Includes photos. A presence in our skies for over half a century, the iconic Boeing 747 has transported hundreds of thousands of passengers across the world. From its introduction with Pan American Airlines in 1970, it has persevered as one of the forerunners of commercial flight. Often labeled the “Queen of the Skies,” this is an aircraft revered by passengers and aircrew alike. The first wide-body airliner ever produced, it has set new standards in air travel and opened up the air routes of the world to vast numbers of people who might otherwise have been unable to afford international air travel. This book focuses not only on the 747, but also its many variants, including the YAL-1A, which Boeing developed for the US Air Force, and the Evergreen 747 Supertanker, a 747-200, modified as an aerial application for fire-fighting. Across its types, the 747 carries around half the world’s air freight. Accordingly, freight variants feature here too, including the 747-8.The sheer size of the workload carried out by this craft is astounding. From the glamorous 1970s, an era of rapid expansion that saw an unprecedented boom in the tourist trade, to the various environmental and economical imperatives that impact upon modern flight, this work shows how the Boeing 747 has been developed in accordance with the changing demands of the ages.
