I've checked and Santa's sleigh is non-EASA, so no issues there!
I hope the 'runway' was icy otherwise I imagine there could be some damage from the sleigh's runners during the touch and goes?!
The issue as far as I was concerned as a child was how Santa managed to visit all the children of the World in one night?! - then my Father explained that due to the rotation of the Earth 'night' lasted a whole day! That explained that then!
