I could double-check the wing orientation, but I'm pretty sure it's right. I did have to build the plane and the trailer side-by-side because the overall length was too long.
I had a weird bug yesterday where the game recorded all of my new and modified blueprints, but did not save my new crate, jiggy, and jingo acquisitions. My newest blueprint had an exclamation point next to it and when I looked, several of the super cubes were that wobbly red when you have a part defined in the vehicle that you don't possess (such as when you buy a Humby blueprint yet don't have all the necessary parts). I thought that was odd. It turns out that I had only 50 of each super body part (instead of 100) and was missing all the other super objects I'd located: fuel, engine, seat, ammo, and wheels. I'd also lost a couple of jiggies, back down to 91 from 93.
At first I was trying to figure out why it didn't save, but then I realized that it had to. How else could I have built those vehicles, whose blueprints were still present, with the super parts in the first place if I didn't have them? Perplexing and I didn't want to have to worry about it so I just beat the game last night.
