 what Santa's sleigh actually looks like in real life. First off, Santa needs room for a lot of presents by our calculations, at least 1.4 billion. So forget just one sleigh. Santa has a whole fleet of sleighs that he pilots remotely from the North Pole. Each has to be the size of the largest ever cargo plane. Also, since Santa only has about 36 hours to deliver all these presents, he needs these unmanned drone-like sleighs to get around as fast as any aircraft has ever gone, which is about nine and a half times the speed of sound, all powered by what else? Reindeer. And to get the presents to every house, each sleigh has an air-to-surface gift launch system similar to missile systems on military drones, which gets them down to each house with pinpoint accuracy. No need to go up on the house top. In total, Santa has over 42,000 of these sleighs to get gifts to all the kids on the nice list. So yeah, Santa is coming to town with the biggest air fleet the world has ever seen.
