I understand if you haven’t been reading Comics Kingdom’s 1943-vintage reruns of Dashiell Hammett and Alex Raymond’s Secret Agent X-9, what with by this time Hammett and Raymond having nothing to do with it. I think it was Robert Storm and Mel Graff by then, and Robert Storm didn’t even exist. But let me catch you up: Secret Agent X-9 is chasing down a baddy named the Little Corporal, a name which I’m sure had no significance at all to readers of 1943.
The Little Corporal has been trying to escape and after his first attempt — disguise himself as a gorilla in a midway show — failed, he ran to the Ferris wheel. It turns out you can’t really escape pursuit in a Ferris wheel, so he jumped down a tree, waved to Fatty Raccoon, and ran to the Scenic Railway roller coaster. So now you’re caught up to seeing how someone can escape on a roller coaster:
By the way the attempt to escape on the Ferris wheel wasn’t even the first time I’ve seen an adventure/crime comic where the bad guy tried to escape on a flat ride. There was a 1930s Dick Tracy adventure where the crook tried to escape on a Caterpillar ride. A Caterpillar was kind of like a Musik Express or Himalaya ride, cars going around and around on the track, but it had a canopy covering the cars most of the ride and the crook snuck out of the ride while the canopy was over. So that was a dumb plan but it was a better grade of dumb than “get on the Ferris wheel and try and climb out when the cops get to the ride platform”.
