Who says the US military has no good purpose?
Every year they track Santa's progress round the world on Christmas Eve and it has become something of a tradition in our house to follow him on his travels.
My daughter is not a child who likes to be early in her bed at night - but as soon as the warning comes that children in Europe should go to bed, she's off there like a shot.
I thought it might be fun to do a bit of a live blog - although we've started late. He's done Australia and New Zealand and is currently in South Korea.
Update 14:53 Santa now in Pyongyang. Hope the brutal North Korean regime don't shoot him down. Maybe the US is trialling cloaking technology or something to make him invisible:-)
15:10 He seems to have survived the totalitarian regime in NK - now at the Great Wall of China. We usually get a video from there......
