The hero, Logan, is the ace interplanetary pilot of the RAF, in a time about 100 years in the future (for example, the story in the 1963 Tiger Annual is set in 2063). In all but the earliest stories, he is accompanied by his regular copilot, Plum-Duff (sometimes Plumduff) Charteris.
Many of the scenarios written in the 1950s still seem insightful half a century later. For example, in one adventure, Jet-ace is involved in fighting a group of aliens who endeavour to destroy humankind by contaminating the atmosphere of the planet.
The Finnish cartoonist Petri Hiltunen created a spoof of Jet-Ace, Rocket Reynolds, under a pseudonym "Valentin Kalpa".
