The North American Aerospace Defense Command's job is to monitor the United States' and Canada's airspace for possible threats.
But this time of year, NORAD tracks the least threatening (and most unusual) flying object of all -- Santa.
The Colorado-based government agency again offers its Official Santa Tracker that follows the jolly one across the globe.
Kids can countdown to Christmas as Santa flits from city to city and even track his progress on Google Earth.
However, NORAD does not have access to the naughty and nice lists.
