Audience versions of this page: FamilyOn December 24, 1955, engineers and navigators at the Continental Air Defense Command (CONAD) Center in Colorado Springs, Colorado, tracked the journey of Santa Claus for the first time. CONAD’s successor, the North American Aerospace Defense Command (NORAD), continues the tradition every December.The first tracking was the result of a mistake in a local newspaper advertisement. The advertiser, Sears, had created a phone number for kids to call “Santa Claus.” Instead of the Sears number, the number to the nearby CONAD headquarters was provided. Instead of redirecting the calls, the CONAD staff used their sophisticated satellite navigation equipment to estimate the route of Santa from the North Pole to spots around the world.Today, NORAD and volunteers work with multinational corporations and government agencies such as NASA to develop “Santa Cams,” which track Santa’s movement over international landmarks.The rest of the year, NORAD is a joint defense organization of the United States and Canada. NORAD is “charged with the missions of aerospace warning and aerospace control for North America. Aerospace warning includes the detection, validation, and warning of attack against North America whether by aircraft, missiles, or space vehicles, through mutual support arrangements with other commands.”
