A well detailed late '70s survey of the world's commercial aircraft that includes the various types of business jets as well as helicopters. The artwork is fair and the cutaways are good as are the foldouts... history of the major manufacturers, technical specs., color photos and cutaway drawings of the major airliners and business jets of the day. There are also a few large 11 x 17 fold out pictures of planes such as the Concorde and the 747-200.
