Santa Tracking

A joint U-S-Canada military operation is launching one of its most crucial annual missions today.

The North American Aerospace Defence Command, or NORAD, will be tracking Santa Claus as he travels around the world.

Beginning at 4 a-m local time, volunteers at the base in Colorado Springs will take calls from children around the world.

Kids — and adults — can also email, or keep an eye on NORAD’s website, Facebook page or Twitter feed to track Santa’s progress.
