Cities in Flight is an omnibus volume of four novels written by James Blish, originally published between 1955 and 1962, which became known over time collectively as the Okie novels. The novels feature entire cities that are able to fly through space using an anti-gravity device, the spindizzy. They cover a span of time of many hundred years, from a very near future to the end of the universe.

The Cities in Flight Novels Edit

They Shall Have StarsEdit

Also published under the title Year 2018!, this novel describes the political and social conditions in the near future when several major technologies are developed which change society radically. These are 'anti-agathic' drugs, which defer or prevent aging, and the development of gravity manipulation, which leads to 'faster-than-light' spaceship drives. During this period the Western democratic government model becomes ever more intolerant, eventually resembling the Soviet model very closely. A principal protagonist of this book, Alaska's US Senator Bliss Wagoner, is eventually executed by an oppressive regime, but not before he has made the technologies which allow mankind to escape their home planet available to all. The book is notable for the detailed way in which it handles technology, providing a mathematical explanation of the principles behind the anti-gravity drive, and illustrations of chemical bonding for reactions in the Ice IV material which is used to build a fixed point 'bridge' on the surface of Jupiter during the drive testing. Politically, the book clearly expresses a strong opposition to McCarthyism, at its peak during the time of writing.

Reviewing a later edition, the Hartford Courant described the novel as "a skillful mixture of human reality and technological fantasy."

A Life for the Stars Edit

Published in 1962, this novel describes the adventures of a young farm boy Chris, co-opted into an Earth city Scranton, Pennsylvania, which has begun travelling in space. The development of the anti-gravity (spindizzy) drives has now enabled very large objects to be enclosed and moved using gravity manipulation. Thus, for instance, mining factories together with associated towns can be moved to bodies of ore, not only on Earth but also amongst the planets in local space. Many of these 'Okie' cities are rejecting Earth jurisdiction, making interstellar journeys, and operating a trading economy out of reach of the Earth authorities. After many adventures Chris eventually becomes a resident of New York, now a major 'Okie' city under its charismatic mayor John Amalfi, being elevated to the newly-created position of city manager due to having a unique, problem-solving skill-set identified by the City Fathers, which are supercomputers who regulate the day-to-day life of the flying city.

===Earthman, Come Home===
Earthman, Come Home (1955, G. P. Putnam's Sons, New York) is the longest book in the series, describing the many adventures of New York under Amalfi, culminating in the installation of a spindizzy drive system on a planet and its use to defend the Earth against an attack from an alien culture living around the Vega star system. Eventually New York is installed on this planet, which is projected out of the Milky Way galaxy towards the Greater Magellanic Cloud, where it encounters a gang of renegade traders who have enslaved the local population.

===A Clash of Cymbals/The Triumph of Time===
A Clash of Cymbals (published in the US as The Triumph of Time) (1959) follows the passage of Amalfi and the 'New Earth' planet undertaking the first ever inter-galactic transit. In the less relativistically-distorted space between the two galaxies evidence of a collision between two universes is detected, a matter-anti-matter collision which reveals the cyclic nature of reality. An alien culture is also investigating this phenomenon, which will shortly accelerate to engulf all galactic space, in other words, the universe will end in a Big Bang. It will be possible to modify the future development of the universes which will emerge from this singularity, and Amalfi directs the 'New Earth' residents to compete with the alien culture (the Web of Hercules) in order to prevent their manipulation of the future of the universe.

As with the other books, a detailed description of the technologies used is provided, including cosmological calculus. While there are some continuity slips, the series presents a unified story of humanity's expansion across the galaxy, and the birth of a new universe.

The spindizzy was used in at least two novels by Jesse Franklin Bone, The Lani People and Confederation Matador and appears as the nickname for fictional Heim Theory devices in Ken Macleod's The Execution Channel.
