But since they went "Okie", it could also work as a series. Though how to
do that and yet keep it distinct in the style of the books is the issue.
Lots of shows do that "Wagon Train" sort of thing, keep the main
characters and move them so each week they can meet some new challenge.
Star Trek took it to the stars, but The Invaders did it on earth, the
aliens were just a method to keep him moving so he'd run into new people
and new problems in each town.
So they'd have to make sure that Cities in Flight as a tv series was
distinctive from "The Star Lost" which had the same basic form, albeit on
a lost 'generation ship".
