This is a tongue-in-cheek letter from a kid wondering how Santa's reindeer fly.
I've got to do a project for my science class, and I'd like to ask you a question: How do the reindeer fly? My Dad says it's some kind of special jet engine, but I'm not sure. I want to make my project about the reindeer, so could you help me? Please write me back and let me know how they get off the ground, how they find where they're going, and how you can go fast enough to get to all the houses in the world in one night. The project is due <date your project due>, so if you could give me an answer soon that would be great.
