One of the things I like about the Fallout aesthetic is the designs for aircraft they use. They have their Fighter Jet, Vertibird, Jet Plane, Stingray, and Jet Airliner, among others. They have that atom-punk vibe that turns out might be truer to life than I previously thought, especially after stumbling over an article called “The 10 Coolest Canceled Aircraft.”
If that makes you want to look at more wings-that-never-were, I found another place that might be of interest: r/WeirdWings. It’s like having a pictorial version of those old shows on the Discovery Channel about secret military aircraft and the early days of flight. It’s also a good resource if you like designing and drawing planes of yore that didn’t quite (if you’ll pardon the expression) get off the ground. I think one could even make a line of “chibi” style planes without too much effort.
Given the history of a few of these things, you might want to bring a parachute.
