NORAD Tracks Santa, the official name of the exercise, began in 1955 when a Colorado Springs newspaper ad invited kids to talk to Santa on a hotline. The phone number had a typo, and dozens of kids wound up dialing the Continental Aerospace Defense Command in Colorado Springs, the predecessor to NORAD. (AP Photo/NORAD, via noradsanta.org)
Volunteers are pulling on their Santa hats, phone lines are set, and tracking screens are ready -- NORAD Tracks Santa is primed for its 57th annual goodwill mission.
Santa trackers start taking calls early Monday, telling children -- and some adults -- when Santa is due at their house. The last shift won't end until nearly 24 hours later.
The number is 877-HI-NORAD or 877-446-6723.
