Santa Claus, An Engineering Retrospective

The question all parents have to hear, at one time or another, "Is Santa real?" Or for the more scholarly children out there, "Is it even a possibility that his task could be achievable?"  You've got to give them an answer, or to them, you'll look even stupider than normal, so here's a couple of references you can use to build your argument for, "yes, dear, he does - in fact, here's scientific proof of his existence."  
SmartTechnology - Technology For Change - Santa's Sleigh Propelled by Smart Technology

In my mind, though, it may just be easier to strip away the fantasy & tell'em he just doesn't exist. 

Is it theoretically possible?...

Or does he?  There are two more arguments on this subject that have been proposed by engineers, who apparently, wish to remain anonymous:


1 - Santa Claus: an Engineering Analysis - 
    
2 - Santa Claus: An Engineering Analysis - REBUTTAL - 

...or is it just another sad lie we tell our kids?

For the real non-believer, check out the website NORAD [North American Aerospace Defense Command] has dedicated to Santa-tracking, in case there's a chance he goes rogue... http://www.noradsanta.org/


And there is even a Santa Claus blog - http://clauschronicles.blogspot.com/ - and this article gives you his house-count.
  
The choice is up to you, do you want your kids living in a fantasy world of flying game, hyper-speed sleighs and all-knowing philanthropic old men?  Given the reality of the world today, maybe that is the way to go.
