Fox News reports:
olunteers are pulling on their Santa hats, phone lines are in place and wall-size tracking screens are ready. NORAD Tracks Santa is primed for its 57th annual goodwill mission.
The first shift of Santa trackers starts taking calls early Monday at 877-HI-NORAD (877-446-6723), telling children — and some adults — when Santa is due at their house. The last shift won't end until nearly 24 hours later.
They'll also post updates online, on Facebook and Twitter.
The volunteers will work from Peterson Air Force Base in Colorado Springs, Colo., home of the North American Aerospace Defense Command.
NORAD, a joint U.S.-Canada command responsible for protecting the skies over both nations, says its Santa-tracking rite was born of a humble typo in a newspaper ad in 1955.
