MegaSack DRAW - This year's winner is user - rgwb
We will be in touch
Just had a look at the NORAD one and its says partnered by Microsoft and Bing Maps. Does that mean it won't work on my iPad, certainly doesn't appear to be....
Am I going to have to use googles instead?
Have you tried GoISSWatch?
My youngest is sat just watching the countdown on the Google tracker!

That's useful Mikey.
The ISS goes over at 5:20ish tonight and will be bladder-releasingly exciting for small people.
That ISS story is brilliant; hope it's a clear night for everyone.
Not just for young people Crispin 
Poor old Santa, never gets to enjoy himself, only comes once a year.
So if Santa's Sleigh/the ISS is said to be at 28 degrees in the sky, how high should I be looking?

My 7 year old knows what the ISS looks like so won't be hoodwinked by such shenanigans

Brilliant clear sky here in he SE, I'm using the GoISSWatch app the kids may even put their iPads down for a few minutes.
That was pretty cool. Where I am there was a load of kids outside that simply went from exited mutterings to rainbow-shitting mental.."SANTA!!!!SANTA!!!"
