Tis the season to be scary, so what does your imagination bring up that will fly? Take a simple model, paint it with seasonal colors, add a few spooky stickers and you’re set. Pass through the Halloween decorations aisle at any store and you will see (with your rocketeer’s eyes) possible structural elements to add to an airframe. It’s a trick to get the weight distribution and surface area balanced for stable flight, but what a treat when it comes together.
