Cities in Flight

no images Cities in Flight is an omnibus volume of four novels, originally published between 1955 and 1962, two of which are fix-ups of pieces that first appeared in various magazines in the early '50s. Despite having been conceived more than 50 years ago, and produced in episodic fashion, they stand head and shoulders above most SF available today. Cities in Flight explores a future built on two crucial discoveries: antigravity devices, which allow whole cities to be lifted from the Earth in order to become giant spaceships; and longevity drugs, which enable people to live for thousands of years.
