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. Volunteer Santa-trackers at NORAD are bracing for tens of thousands of calls and emails on Christmas Eve this year. (AP Photo/NORAD, via noradsanta.org)
