It’s Christmas Eve, and Santa is preparing to make the trip worldwide, delivering gifts to the estimated two billion children awaiting his arrival. In its 69th year, the North American Aerospace Defense Command Center is already tracking the big man on the journey using the NORAD Tracks Santa (NTS) system. Families can track Santa’s location in real time through the NTS website and mobile app. The program started back in 1955 when a young child accidentally called the unlisted number for the Continental Air Defense Command’s Operations Center when trying to reach Old St. Nick, creating this tradition for all ages. Track Santa by visiting the website included below, by phone 1(877)HI-NORAD (466-6723), or on the mobile app “NORAD Tracks Santa” in the App Store or Google Play.
