Saint Nicholas is getting ready for his yearly trip around the world in one night.
Scientists have wondered how he is able to do it all in one night but no one has ever come up with an adequate explanation.
Ideas about his secret travel abilities range all the way from alien technology to magic fairy dust.
The North American Aerospace Defence Command, a joint force of both US and Canadian forces, keep tabs on Santa every year as he flies over the US and Canada.
Santa's flight plan has been given top clearance and the full force of the US Air Force stands ready to keep the skies safe for Santa and his eight amazingly fast reindeer.
You can track Santa Clause as he makes his way across North America from the Norad website.
Merry Christmas to all and to all a good night!
