The U.S. and Canadian military will entertain millions of kids again this Christmas Eve with second-by-second updates on Santa's global whereabouts.
NORAD is a U.S.-Canadian operation based at Peterson Air Force Base in Colorado Springs, Colorado. It's charged with defending the skies over both nations and monitoring sea approaches.
The Santa program began in 1955 when a typo in a newspaper advertisement had children calling the hotline of NORAD's predecessor, asking to talk to Santa.
It's now a Christmas tradition that thrills millions of kids, and parents.
The special hotline for talking with Santa is 877-HI-NORAD.
