he wouldn't show up on radar he is going too quickly.
There are approximately two billion children in the world. Apparently Santa doesn’t visit Jewish Muslim or Buddhist children so we can reduce the number to around 400 million. Let’s say on average there are three children to every household. So Santa has over 133 million homes to visit in one night!
fvvvffffffvvvf
Assuming that Santa travels from east to west and has to cross over various time zones, I reckon he has around 31 hours of Christmas Day in which to deliver all the presents. That makes 1,157.4 houses to call on every single second.
fvvvffffffvvvf
So Santa has approximately 0.006324 of a second to park his sleigh on the roof, scramble down the chimney, put the prezies in the stocking, drink the sherry and scoff the mince pie so thoughtfully left out for him, clamber back up the chimney, jump back into his sleigh and zoom off to his next customer.
fvvvffffffvvvf
Let’s say that these 133 million houses that Santa visits are evenly distributed with a distance of say 50 feet between each one plus a return trip down the chimney of an average 20 feet the total distance traveled will be in the region of 9,041,608,800 feet or 1,712,425 miles or 71 circumnavigation’s of the earth
If the Wright brothers plane, The Flyer were reliable enough to fly the same distance at its top speed of 30 mph the flight would have taken six and a half years.
fvvvffffffvvvf
Therefore the average speed Santa travels on Christmas night will be over 55 thousand miles an hour or 276 time faster that the fastest ever Ferrari. In other words the distance Santa travels in one second would take a Ferrari over four and a half-hours flat out.

Now whilst Mr. Claus is popping in on all these children he is also scoffing the mince pies and sherry. Maybe he’d be lucky to find these treats at half of the homes he calls on. We’re talking 66,500,000 mince pies and 66,500,000 glasses of sherry. Approximately eight glasses to a bottle would mean Father Christmas knocking back just under 8.5 million bottles of sherry. And if each mince pie weighed approximately 2 oz Santa’s total intake of mince pies would be about 3,700 tons.
fvvvffffffvvvf
If each prezzie weighed in at around 5lb there would be 892,857 tons of presents on the back of Santa’s sleigh. Add that to the 3,700 tons that Santa has scoffed in mince pies, plus around another 500 tons of sherry and another couple of tons for the sleigh itself you’d have a combined weight of nearly 900,000 tons or the Equivalent of 160,714 African Elephants.
However, considering that for each 30lbs of prezzies Santa drops off he is gaining 2oz in mince pie and just over a quarter of an ounce in sherry. So, by the end of the Christmas day he will have displaced around 896,000 tons or the equivalent of 13 QE2’s.
fvvvffffffvvvf
So, to sum things up, we have a fat jolly bloke dressed in red whizzing around the planet in a sleigh pulled by six reindeers at around Mach 82. He is delivering a pile of prezzies, which would fill Trafalgar Square at least a couple of dozen times for half the houses in the world, some, of which don’t even have chimneys.
