At the end of the 19th century, brilliant inventor Professor Jonathan T. Buck, crafted a beautiful steam-powered airship for an expedition to South America's Amazon River Basin in search of a magnificent lost city, but the mission ended in disaster and they vanished. More than a century later, an expedition discovered this notebook: a riveting account that reveals not only just how Buck drew up the plans for his airship, but what fate befell the expedition. Part drawing guide, part historical saga, this book will transport readers to a world when steam power, gadgets, gases and gizmos took us into the skies.
