Radio Flyer is a cancelled flying game that was in development by Ocean in 1992 for the Super Nintendo. It seems that the project was based on the film with the same name from Columbia Pictures, in which 2 young brothers escape their chaotic family life with dreams of flying. Inspired by a local legend, they attempt to build a working airplane from their ordinary red wagon.
Celine was able to find a couple fo screenshot from the game in Console Mania #13 (an italian magazine), PlayerOne #23 and EGM #25. Looking at those we can speculate that Radio Flyer could have been somehow similar to Pilot Wings SNES. The project was canned for unknown reasons but as Evan G from SNES Central has wrote, it could be because the movie was a flop / sucked.
Thanks to Celine for the contribution!
