Tom Swift and his Airship

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 half-way 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. (Summary by Wikipedia)
