Before Speed Carter: SpaceMan, Atlas' resident space hero was Jet Dixon...
...leader of the circa-2000 AD Space Squadron in the 1951-52 series of the same name!
I'm still waiting for my flying car, much less interplanetary travel...
This premiere story from Space Squadron #1 was illustrated by George Tuska who later became the final artist on the original Buck Rogers comic strip (1959-67) and then assumed the art duties for almost a decade on Marvel's Invincible Iron Man!
The writer is unknown, but the scripting is clearly far more simplistic and juvenile-oriented than Speed Carter a couple of years later!
