Just re-posting from last year as it's great fun for your children.

NORAD’s (North American Aerospace Defense Command) annual tracking of Santa's path around the globe began in1955 after a Colorado Springs-based Sears Roebuck & Co ran a store advertisement for children to call Santa on a special "hotline" but inadvertently misprinted telephone number. Instead of Santa, the phone number put kids through NORAD. The Director or of Operations, Colonel Harry Shoup realized what had happened, and had his staff check radar data to see if there was any indication of Santa making his way south from the North Pole and this is how it has become a tradition that NORAD tracks Santa.

If you want to track Santa this year go to www.noradsanta.org

Want some insight into world changes then view this PowerPoint presentation entitled "shifthappens"  it's quite scary. Although its a 25mb download it's worth it. If you don't have PowerPoint you can download the viewer from here

On this Sunday's Top Gear, we've got a man who can drive an F1 car very fast, and a man who, well, can't.

The man who can is Lewis Hamilton. You might have heard of him. The McLaren star joins Jeremy in the TG studio to discuss his first season in Formula One and, more importantly, straps himself into our old Suzuki Liana to see how he measures up against Mansell, Hill and the rest of the F1 drivers who have taken to our test track.
