"For more than 50 years, NORAD and its predecessor, the Continental Air Defense Command (CONAD) have tracked Santa's flight.
The tradition began in 1955 after a Colorado Springs-based Sears Roebuck & Co. advertisement misprinted the telephone number for children to call Santa. Instead of reaching Santa, the phone number put kids through to the CONAD Commander-in-Chief's operations "hotline." The Director of Operations at the time, Colonel Harry Shoup, had his staff check the radar for indications of Santa making his way south from the North Pole. Children who called were given updates on his location, and a tradition was born.
In 1958, the governments of Canada and the United States created a bi-national air defense command for North America called the North American Aerospace Defense Command, also known as NORAD, which then took on the tradition of tracking Santa.
Since that time, NORAD men, women, family and friends have selflessly volunteered their time to personally respond to phone calls and emails from children all around the world. In addition, we now track Santa using the internet. Millions of people who want to know Santa's whereabouts now visit the NORAD Tracks Santa website." (from http://www.noradsanta.org/en/)
This year, in addition to tracking Santa on your computer, NORAD is offering a Santa Tracking App. With this app, you'll now know, as you're out and about on Christmas Eve, where Santa is en route.
Coming home from midnight service and worried that you might bump into Santa as you off-load sleepy children from car to bed? Not to worry, the app will let you know if you need to drive home a bit slower or take a last turn to look at lights and decorations to avoid a fateful meeting. Or for those young kids who camp near the tree in hopes of getting a glimpse of the jovial man, this app might make their plotting a bit easier.
Thank you to NORAD and all of its volunteers for it's continued dedication to keeping us alert of Santa's whereabouts.
