Every Christmas Eve, the good folks at the North American Aerospace Defense Command track Santa on their radar systems. At their Website, you can find out the technical details of how they accomplish this feat (it involves the infrared signal given off by Rudolph's nose). Is Santa near your house? You won't be able to find out until Christmas Eve when the tracking goes live, but until then you can watch video from last year Don't forget to come back Christmas Eve; you might catch Santa on a fighter jet's Santa Cam!
