This website is sponsored by the North American Aerospace Defense Command (NORAD) which is the joint American and Canadian military organization responsible for the aerospace defense of the United States and Canada that was created in 1958. Every year NORAD tracks Santa's whereabouts so that children throughout the world can determine his location and how close he is to delivering goodies to their house on Christmas Eve. At the site (under the link for Secret Santa Files in the NORAD HQ section) you can get the scoop on the science behind tracking Santa including radar, satellites, and jet fighter aircraft!
