WASHINGTON (AP) — As children around the world eagerly await Santa’s arrival on Christmas, the military is ready to track him and see if he’s using any new technology.

Armed with radars, sensors and aircraft, the North American Aerospace Defense Command in Colorado keeps a close watch on Santa and his sleigh from the moment he leaves the North Pole. And it once again will share all those details so everyone can follow along as Santa travels the globe beginning Christmas Eve.

NORAD, the military command that is responsible for protecting North American airspace, has launched its noradsanta.org website, social media sites and mobile app, loaded with games, movies, books and music. And there’s a countdown clock showing when the official tracking of the sleigh will start.
