An illustrated guide, in both book and CD-ROM, of landscapes seen from commercial airplane windows across the United States. This is a guide to what an airline passenger sees from his seat while flying over the United States. Through its ingenious construction and a map of preferred flight paths, it's easy to find those pages that correspond to whatever flight a passenger happens to be on, and then to identify features that can be seen from the air. The book marries geology, natural history, and human history for a glorious portrait of the continent, from the Atlantic City Boardwalk to Mount St. Helens. Each two-page spread features an aerial photo with captions identifying features passengers will see and an essay interpreting the features. Each chapter is a Flight Corridor, with pages sequenced to follow a trip from takeoff to landing. Because many flight paths overlap, the fifteen corridors cover the forty most heavily traveled flight segments in the continental United States, plus many others. In many regions of the country, readers will have a new page to read about every twenty minutes. The entire book is also on the included CD-ROM, which can easily be used on a laptop in the air.
