Jetpacks was yes!

I don't consider this under consideration for the competition, as it's wildly incomplete, but I wanted to include it here since this is what inspired it. I'm really new to Blender, less than a month, so I just didn't have time to skill ratio required to do what I wanted in time. This is, outside of tutorials, my first model/render.
As you can probably tell there's a lot of detail missing. There's a bunch of stuff I didn't get around to modeling. Nothing is textured or (appropriately) uv mapped. There's some weirdness going on in a couple of places that needs to be cleaned up. Lots of stuff yet to do, but for my first model I'm happy with the direction it's going.
