Santa is on a worldwide sleigh ride and NORAD, or North American Aerospace Defense Command, is tracking it all. But why?
It started in 1955 when a Sears ad listed Santa's number but misprinted it and actually directed children to a confidential line belonging to Col. Shoup, the command center's head honcho.
Once the colonel caught the error, he'd already caught the Christmas spirit and took it one step further. His children explained it to NPR.
"Next thing you know, dad had called the radio station and had said, 'This is the commander at the Combat Alert Center, and we have an unidentified flying object. Why, it looks like a sleigh,'" his children shared.
So you better watch out, you better not cry because Santa Claus is coming to a radar near you.
