Santa's Air Freight Airline Co. has finished flying around Australia delivering gifts to all who have been good.
He was smart enough to avoid Radar and had a discrete Transponder code so that kids could not track him and spoil their surprise.
It was fortunate that his flying was done mostly in CTA but at night when there was much less Air Traffic.
No TCAS warnings so his flight was uneventful.
MERRY CHRISTMAS to all fellow flyers.
