NORAD creates Santa tracking app

For more than 50 years, NORAD — the North American Aerospace Defense Command — has used its high-tech missile-tracking systems to track Santa’s progress during his annual Christmas Eve flight around the world.

For a 24-hour period, about 1,200 military volunteers take shifts manning the command center at Peterson Air Force Base in Colorado; they monitor radar screens and field calls from excited 7-year-olds who ask for updates on Santa’s location. They also update Kris Kringle’s progress on the Google Earth map on the NORAD Tracks Santa website, as well as the Facebook page and the Twitter feed.
