Plot summary
In Tom Swift and His Airship, Tom Swift has finished his latest invention- the Red Cloud, a fast and innovative airship. Tom is anxious for a cross-country trial, but just before he and his friends take off, the Shopton bank is robbed. No sooner is Tom in the air than he is blamed for the robbery. Suddenly, he's a wanted fugitive but doesn't know why until he's halfway across the country. With no safe harbor or friend on the land below, Tom must race back to Shopton to clear his name before he's shot out of the sky.

Inventions & innovation

 * Tom Swift, and his friend (John Sharp - aeronaut extraordinaire), designed and built the Red Cloud: an airship that was half blimp/dirigible and half airplane. In fact, it had two wings (like the World War I biplanes) extending out from a spacious gondola which sat beneath the rather voluminous gas-filled balloon. It was fast, achieving over 80 mph if pressed, and could stay in the air for two weeks at a time, if Tom wanted. Perhaps the most fantastic element of the craft was the gondola, which was luxuriously appointed with multiple rooms; e.g., a kitchen, an engine room, and a first-rate observation room from which Tom would steer the ship, while looking out the surrounding windows.
 * Barton Swift, Tom's father, is nearing completion of a submarine design that promises to be the most advanced in the world.
