The Tom Swift Omnibus #6 - A Positronic Book Tom Swift and His Giant Cannon, Tom Swift and His Photo Telephone, Tom Swift and His Aerial Warship

A cannon capable of firing farther than any weapon ever built, a telephone that transmits moving images, and an armored airship designed to rule the skies-Tom Swift's latest inventions may change the future, provided his enemies do not destroy them first. In these three complete adventures, the young inventor confronts sabotage, criminal conspiracies, international intrigue, and the dangerous consequences of technology falling into the wrong hands. In Tom Swift and His Giant Cannon, Tom is asked to create an enormous long-range weapon capable of defending a strategic canal from attack. Developing and testing the cannon demands new explosives, daring experiments, and a dangerous journey to a tropical stronghold threatened by revolutionaries. Tom Swift and His Photo Telephone follows his attempt to perfect a remarkable device that allows callers to see one another across great distances. When a valuable business figure disappears and a fortune hangs in the balance, Tom's invention becomes the key to exposing a carefully planned crime. In Tom Swift and His Aerial Warship, Tom constructs a heavily armed flying machine intended to protect the nation from attack. Foreign agents and unscrupulous rivals are determined to steal its secrets, forcing Tom and his companions into a struggle that carries them from the workshop into the skies. Combining speculative technology, espionage, mechanical ingenuity, and breathless adventure, The Tom Swift Omnibus #6 captures an era fascinated by the promise-and increasingly aware of the dangers-of modern invention. Tom Swift and His Photo Telephone is also notable for imagining picture-based telephone communication decades before video calling became commonplace.
