I love this story - what a nice guy taking the time out to talk to the kids who rang instead of getting all "official"

The Command carried out its first Santa tracking in 1958 after inheriting the tradition from CONAD. Since that time, Canadian and American men and women who work at NORAD have responded to phone calls from children personally. Additionally, media from all over the world call NORAD on Christmas Eve for updates on Santa's location. Last year this Web site was visited by millions of people who wanted to know Santa's whereabouts. This year, the information is provided in six languages.
NORAD relies on many volunteers to help make Santa tracking possible. Many people at Cheyenne Mountain and Peterson Air Force Base spend part of their Christmas Eve with their families and friends at NORAD's Santa Tracking Operations Center in order to answer phones and provide Santa updates to the many thousands of children who call in.
