The Sunday strip ran in the New York Daily News from February 17, 1952, to March 13, 1955, initially as a full tabloid page and, near the end, as a half tab.

[1][2] Williamson said his plot formula was heavily inspired by the strip Dick Tracy, in that each episode involved a conflict with a new villain and a new group of colorful characters.

[2] The strip's storyline was loosely based on Seetee Ship: in the year 2191, freelance pilot and "spatial engineer" Mike Flint carried out odd jobs - usually on behalf of beautiful women - across the wild frontier of the asteroid belt.

Flint had a base on the small habitable asteroid of Brooklyn Rock, from where he and his alien partner/sidekick Tham Thmith (a Venusian with metal-based biology and a speech impediment) operated a classic Art-Deco rocketship powered by antimatter.
